    Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
 
    Section 5. The Illinois Income Tax Act is amended by
changing Sections 203, 204, 205, 207, 214, 220, 304, 502, 506,
601, 701, 702, 703, 704A, 709.5, 804, 909, 911, 1002, 1101,
1402, 1405.4, and 1501 as follows:
 
    (35 ILCS 5/203)  (from Ch. 120, par. 2-203)
    Sec. 203. Base income defined.
    (a) Individuals.
        (1) In general. In the case of an individual, base
    income means an amount equal to the taxpayer's adjusted
    gross income for the taxable year as modified by paragraph
    (2).
        (2) Modifications. The adjusted gross income referred
    to in paragraph (1) shall be modified by adding thereto the
    sum of the following amounts:
            (A) An amount equal to all amounts paid or accrued
        to the taxpayer as interest or dividends during the
        taxable year to the extent excluded from gross income
        in the computation of adjusted gross income, except
        stock dividends of qualified public utilities
        described in Section 305(e) of the Internal Revenue
        Code;
            (B) An amount equal to the amount of tax imposed by
        this Act to the extent deducted from gross income in
        the computation of adjusted gross income for the
        taxable year;
            (C) An amount equal to the amount received during
        the taxable year as a recovery or refund of real
        property taxes paid with respect to the taxpayer's
        principal residence under the Revenue Act of 1939 and
        for which a deduction was previously taken under
        subparagraph (L) of this paragraph (2) prior to July 1,
        1991, the retrospective application date of Article 4
        of Public Act 87-17. In the case of multi-unit or
        multi-use structures and farm dwellings, the taxes on
        the taxpayer's principal residence shall be that
        portion of the total taxes for the entire property
        which is attributable to such principal residence;
            (D) An amount equal to the amount of the capital
        gain deduction allowable under the Internal Revenue
        Code, to the extent deducted from gross income in the
        computation of adjusted gross income;
            (D-5) An amount, to the extent not included in
        adjusted gross income, equal to the amount of money
        withdrawn by the taxpayer in the taxable year from a
        medical care savings account and the interest earned on
        the account in the taxable year of a withdrawal
        pursuant to subsection (b) of Section 20 of the Medical
        Care Savings Account Act or subsection (b) of Section
        20 of the Medical Care Savings Account Act of 2000;
            (D-10) For taxable years ending after December 31,
        1997, an amount equal to any eligible remediation costs
        that the individual deducted in computing adjusted
        gross income and for which the individual claims a
        credit under subsection (l) of Section 201;
            (D-15) For taxable years 2001 and thereafter, an
        amount equal to the bonus depreciation deduction taken
        on the taxpayer's federal income tax return for the
        taxable year under subsection (k) of Section 168 of the
        Internal Revenue Code;
            (D-16) If the taxpayer sells, transfers, abandons,
        or otherwise disposes of property for which the
        taxpayer was required in any taxable year to make an
        addition modification under subparagraph (D-15), then
        an amount equal to the aggregate amount of the
        deductions taken in all taxable years under
        subparagraph (Z) with respect to that property.
            If the taxpayer continues to own property through
        the last day of the last tax year for which the
        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was allowed in any taxable year to make a subtraction
        modification under subparagraph (Z), then an amount
        equal to that subtraction modification.
            The taxpayer is required to make the addition
        modification under this subparagraph only once with
        respect to any one piece of property;
            (D-17) An amount equal to the amount otherwise
        allowed as a deduction in computing base income for
        interest paid, accrued, or incurred, directly or
        indirectly, (i) for taxable years ending on or after
        December 31, 2004, to a foreign person who would be a
        member of the same unitary business group but for the
        fact that foreign person's business activity outside
        the United States is 80% or more of the foreign
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304. The addition modification
        required by this subparagraph shall be reduced to the
        extent that dividends were included in base income of
        the unitary group for the same taxable year and
        received by the taxpayer or by a member of the
        taxpayer's unitary business group (including amounts
        included in gross income under Sections 951 through 964
        of the Internal Revenue Code and amounts included in
        gross income under Section 78 of the Internal Revenue
        Code) with respect to the stock of the same person to
        whom the interest was paid, accrued, or incurred.
            This paragraph shall not apply to the following:
                (i) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person who
            is subject in a foreign country or state, other
            than a state which requires mandatory unitary
            reporting, to a tax on or measured by net income
            with respect to such interest; or
                (ii) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer can establish, based on a
            preponderance of the evidence, both of the
            following:
                    (a) the person, during the same taxable
                year, paid, accrued, or incurred, the interest
                to a person that is not a related member, and
                    (b) the transaction giving rise to the
                interest expense between the taxpayer and the
                person did not have as a principal purpose the
                avoidance of Illinois income tax, and is paid
                pursuant to a contract or agreement that
                reflects an arm's-length interest rate and
                terms; or
                (iii) the taxpayer can establish, based on
            clear and convincing evidence, that the interest
            paid, accrued, or incurred relates to a contract or
            agreement entered into at arm's-length rates and
            terms and the principal purpose for the payment is
            not federal or Illinois tax avoidance; or
                (iv) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer establishes by clear and convincing
            evidence that the adjustments are unreasonable; or
            if the taxpayer and the Director agree in writing
            to the application or use of an alternative method
            of apportionment under Section 304(f).
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (D-18) An amount equal to the amount of intangible
        expenses and costs otherwise allowed as a deduction in
        computing base income, and that were paid, accrued, or
        incurred, directly or indirectly, (i) for taxable
        years ending on or after December 31, 2004, to a
        foreign person who would be a member of the same
        unitary business group but for the fact that the
        foreign person's business activity outside the United
        States is 80% or more of that person's total business
        activity and (ii) for taxable years ending on or after
        December 31, 2008, to a person who would be a member of
        the same unitary business group but for the fact that
        the person is prohibited under Section 1501(a)(27)
        from being included in the unitary business group
        because he or she is ordinarily required to apportion
        business income under different subsections of Section
        304. The addition modification required by this
        subparagraph shall be reduced to the extent that
        dividends were included in base income of the unitary
        group for the same taxable year and received by the
        taxpayer or by a member of the taxpayer's unitary
        business group (including amounts included in gross
        income under Sections 951 through 964 of the Internal
        Revenue Code and amounts included in gross income under
        Section 78 of the Internal Revenue Code) with respect
        to the stock of the same person to whom the intangible
        expenses and costs were directly or indirectly paid,
        incurred, or accrued. The preceding sentence does not
        apply to the extent that the same dividends caused a
        reduction to the addition modification required under
        Section 203(a)(2)(D-17) of this Act. As used in this
        subparagraph, the term "intangible expenses and costs"
        includes (1) expenses, losses, and costs for, or
        related to, the direct or indirect acquisition, use,
        maintenance or management, ownership, sale, exchange,
        or any other disposition of intangible property; (2)
        losses incurred, directly or indirectly, from
        factoring transactions or discounting transactions;
        (3) royalty, patent, technical, and copyright fees;
        (4) licensing fees; and (5) other similar expenses and
        costs. For purposes of this subparagraph, "intangible
        property" includes patents, patent applications, trade
        names, trademarks, service marks, copyrights, mask
        works, trade secrets, and similar types of intangible
        assets.
            This paragraph shall not apply to the following:
                (i) any item of intangible expenses or costs
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person who is
            subject in a foreign country or state, other than a
            state which requires mandatory unitary reporting,
            to a tax on or measured by net income with respect
            to such item; or
                (ii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, if the taxpayer can establish, based
            on a preponderance of the evidence, both of the
            following:
                    (a) the person during the same taxable
                year paid, accrued, or incurred, the
                intangible expense or cost to a person that is
                not a related member, and
                    (b) the transaction giving rise to the
                intangible expense or cost between the
                taxpayer and the person did not have as a
                principal purpose the avoidance of Illinois
                income tax, and is paid pursuant to a contract
                or agreement that reflects arm's-length terms;
                or
                (iii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person if the
            taxpayer establishes by clear and convincing
            evidence, that the adjustments are unreasonable;
            or if the taxpayer and the Director agree in
            writing to the application or use of an alternative
            method of apportionment under Section 304(f);
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (D-19) For taxable years ending on or after
        December 31, 2008, an amount equal to the amount of
        insurance premium expenses and costs otherwise allowed
        as a deduction in computing base income, and that were
        paid, accrued, or incurred, directly or indirectly, to
        a person who would be a member of the same unitary
        business group but for the fact that the person is
        prohibited under Section 1501(a)(27) from being
        included in the unitary business group because he or
        she is ordinarily required to apportion business
        income under different subsections of Section 304. The
        addition modification required by this subparagraph
        shall be reduced to the extent that dividends were
        included in base income of the unitary group for the
        same taxable year and received by the taxpayer or by a
        member of the taxpayer's unitary business group
        (including amounts included in gross income under
        Sections 951 through 964 of the Internal Revenue Code
        and amounts included in gross income under Section 78
        of the Internal Revenue Code) with respect to the stock
        of the same person to whom the premiums and costs were
        directly or indirectly paid, incurred, or accrued. The
        preceding sentence does not apply to the extent that
        the same dividends caused a reduction to the addition
        modification required under Section 203(a)(2)(D-17) or
        Section 203(a)(2)(D-18) of this Act.
            (D-20) For taxable years beginning on or after
        January 1, 2002 and ending on or before December 31,
        2006, in the case of a distribution from a qualified
        tuition program under Section 529 of the Internal
        Revenue Code, other than (i) a distribution from a
        College Savings Pool created under Section 16.5 of the
        State Treasurer Act or (ii) a distribution from the
        Illinois Prepaid Tuition Trust Fund, an amount equal to
        the amount excluded from gross income under Section
        529(c)(3)(B). For taxable years beginning on or after
        January 1, 2007, in the case of a distribution from a
        qualified tuition program under Section 529 of the
        Internal Revenue Code, other than (i) a distribution
        from a College Savings Pool created under Section 16.5
        of the State Treasurer Act, (ii) a distribution from
        the Illinois Prepaid Tuition Trust Fund, or (iii) a
        distribution from a qualified tuition program under
        Section 529 of the Internal Revenue Code that (I)
        adopts and determines that its offering materials
        comply with the College Savings Plans Network's
        disclosure principles and (II) has made reasonable
        efforts to inform in-state residents of the existence
        of in-state qualified tuition programs by informing
        Illinois residents directly and, where applicable, to
        inform financial intermediaries distributing the
        program to inform in-state residents of the existence
        of in-state qualified tuition programs at least
        annually, an amount equal to the amount excluded from
        gross income under Section 529(c)(3)(B).
            For the purposes of this subparagraph (D-20), a
        qualified tuition program has made reasonable efforts
        if it makes disclosures (which may use the term
        "in-state program" or "in-state plan" and need not
        specifically refer to Illinois or its qualified
        programs by name) (i) directly to prospective
        participants in its offering materials or makes a
        public disclosure, such as a website posting; and (ii)
        where applicable, to intermediaries selling the
        out-of-state program in the same manner that the
        out-of-state program distributes its offering
        materials;
            (D-21) For taxable years beginning on or after
        January 1, 2007, in the case of transfer of moneys from

        amount of moneys previously deducted from base income
        under subsection (a)(2)(Y) of this Section;
            (D-22) For taxable years beginning on or after
        January 1, 2009, in the case of a nonqualified
        withdrawal or refund of moneys from a qualified tuition
        program under Section 529 of the Internal Revenue Code

        qualified expenses at an eligible education
        institution, an amount equal to the contribution
        component of the nonqualified withdrawal or refund
        that was previously deducted from base income under
        subsection (a)(2)(y) of this Section, provided that
        the withdrawal or refund did not result from the
        beneficiary's death or disability;

        religious reasons by Nazi Germany or any other Axis
        regime or as an heir of the victim and (ii) items of
        income, to the extent includible in gross income for
        federal income tax purposes, attributable to, derived

        as insurance under policies issued to a victim of
        persecution for racial or religious reasons by Nazi
        Germany or any other Axis regime by European insurance
        companies immediately prior to and during World War II;
        provided, however, this subtraction from federal
        adjusted gross income does not apply to assets acquired
        with such assets or with the proceeds from the sale of
        such assets; provided, further, this paragraph shall
        only apply to a taxpayer who was the first recipient of
        such assets after their recovery and who is a victim of
        persecution for racial or religious reasons by Nazi
        Germany or any other Axis regime or as an heir of the
        victim. The amount of and the eligibility for any
        public assistance, benefit, or similar entitlement is

        thereafter, an amount equal to "x", where:
                (1) "y" equals the amount of the depreciation
            deduction taken for the taxable year on the

                0.429); and
                    (ii) for property on which a bonus
                depreciation deduction of 50% of the adjusted
                basis was taken, "x" equals "y" multiplied by

        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was required in any taxable year to make an addition
        modification under subparagraph (D-15), then an amount
        equal to that addition modification.
            The taxpayer is allowed to take the deduction under
        this subparagraph only once with respect to any one
        piece of property.

        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited

        taxable year under Section 203(a)(2)(D-18) for
        intangible expenses and costs paid, accrued, or
        incurred, directly or indirectly, to the same foreign
        person. This subparagraph (EE) is exempt from the
        provisions of Section 250; and
            (FF) An amount equal to any amount awarded to the
        taxpayer during the taxable year by the Court of Claims
        under subsection (c) of Section 8 of the Court of
        Claims Act for time unjustly served in a State prison.
        This subparagraph (FF) is exempt from the provisions of
        Section 250; and .

        deduction for federal income tax purposes if the
        expense or loss had been uninsured. If a taxpayer makes
        the election provided for by this subparagraph (GG),
        the insurer to which the premiums were paid must add
        back to income the amount subtracted by the taxpayer
        pursuant to this subparagraph (GG). This subparagraph
        (GG) is exempt from the provisions of Section 250.

    of the following amounts:
            (A) An amount equal to all amounts paid or accrued

        taken in arriving at taxable income, other than a net
        operating loss carried forward from a taxable year
        ending prior to December 31, 1986;

                (i) the addition modification relating to the
            net operating loss carried back or forward to the
            taxable year from any taxable year ending prior to
            December 31, 1986 shall be reduced by the amount of
            addition modification under this subparagraph (E)
            which related to that net operating loss and which
            was taken into account in calculating the base
            income of an earlier taxable year, and
                (ii) the addition modification relating to the
            net operating loss carried back or forward to the
            taxable year from any taxable year ending prior to
            December 31, 1986 shall not exceed the amount of
            such carryback or carryforward;
            For taxable years in which there is a net operating
        loss carryback or carryforward from more than one other
        taxable year ending prior to December 31, 1986, the
        addition modification provided in this subparagraph
        (E) shall be the sum of the amounts computed
        independently under the preceding provisions of this
        subparagraph (E) for each such taxable year;
            (E-5) For taxable years ending after December 31,
        1997, an amount equal to any eligible remediation costs

        Internal Revenue Code;
            (E-11) If the taxpayer sells, transfers, abandons,
        or otherwise disposes of property for which the
        taxpayer was required in any taxable year to make an

        an amount equal to the aggregate amount of the
        deductions taken in all taxable years under
        subparagraph (T) with respect to that property.
            If the taxpayer continues to own property through
        the last day of the last tax year for which the
        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was allowed in any taxable year to make a subtraction
        modification under subparagraph (T), then an amount

        member of the same unitary business group but for the
        fact the foreign person's business activity outside
        the United States is 80% or more of the foreign
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304. The addition modification
        required by this subparagraph shall be reduced to the
        extent that dividends were included in base income of
        the unitary group for the same taxable year and
        received by the taxpayer or by a member of the
        taxpayer's unitary business group (including amounts
        included in gross income pursuant to Sections 951
        through 964 of the Internal Revenue Code and amounts
        included in gross income under Section 78 of the
        Internal Revenue Code) with respect to the stock of the
        same person to whom the interest was paid, accrued, or
        incurred.
            This paragraph shall not apply to the following:
                (i) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person who
            is subject in a foreign country or state, other
            than a state which requires mandatory unitary
            reporting, to a tax on or measured by net income
            with respect to such interest; or
                (ii) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer can establish, based on a
            preponderance of the evidence, both of the
            following:
                    (a) the person, during the same taxable
                year, paid, accrued, or incurred, the interest
                to a person that is not a related member, and
                    (b) the transaction giving rise to the
                interest expense between the taxpayer and the
                person did not have as a principal purpose the
                avoidance of Illinois income tax, and is paid
                pursuant to a contract or agreement that
                reflects an arm's-length interest rate and
                terms; or
                (iii) the taxpayer can establish, based on
            clear and convincing evidence, that the interest
            paid, accrued, or incurred relates to a contract or
            agreement entered into at arm's-length rates and
            terms and the principal purpose for the payment is
            not federal or Illinois tax avoidance; or
                (iv) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer establishes by clear and convincing
            evidence that the adjustments are unreasonable; or
            if the taxpayer and the Director agree in writing
            to the application or use of an alternative method
            of apportionment under Section 304(f).
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (E-13) An amount equal to the amount of intangible
        expenses and costs otherwise allowed as a deduction in
        computing base income, and that were paid, accrued, or
        incurred, directly or indirectly, (i) for taxable
        years ending on or after December 31, 2004, to a
        foreign person who would be a member of the same
        unitary business group but for the fact that the
        foreign person's business activity outside the United
        States is 80% or more of that person's total business
        activity and (ii) for taxable years ending on or after
        December 31, 2008, to a person who would be a member of
        the same unitary business group but for the fact that
        the person is prohibited under Section 1501(a)(27)
        from being included in the unitary business group
        because he or she is ordinarily required to apportion
        business income under different subsections of Section
        304. The addition modification required by this
        subparagraph shall be reduced to the extent that
        dividends were included in base income of the unitary
        group for the same taxable year and received by the
        taxpayer or by a member of the taxpayer's unitary
        business group (including amounts included in gross
        income pursuant to Sections 951 through 964 of the
        Internal Revenue Code and amounts included in gross
        income under Section 78 of the Internal Revenue Code)
        with respect to the stock of the same person to whom
        the intangible expenses and costs were directly or
        indirectly paid, incurred, or accrued. The preceding
        sentence shall not apply to the extent that the same
        dividends caused a reduction to the addition
        modification required under Section 203(b)(2)(E-12) of
        this Act. As used in this subparagraph, the term
        "intangible expenses and costs" includes (1) expenses,
        losses, and costs for, or related to, the direct or
        indirect acquisition, use, maintenance or management,
        ownership, sale, exchange, or any other disposition of
        intangible property; (2) losses incurred, directly or
        indirectly, from factoring transactions or discounting
        transactions; (3) royalty, patent, technical, and
        copyright fees; (4) licensing fees; and (5) other
        similar expenses and costs. For purposes of this
        subparagraph, "intangible property" includes patents,
        patent applications, trade names, trademarks, service
        marks, copyrights, mask works, trade secrets, and
        similar types of intangible assets.
            This paragraph shall not apply to the following:
                (i) any item of intangible expenses or costs
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person who is
            subject in a foreign country or state, other than a
            state which requires mandatory unitary reporting,
            to a tax on or measured by net income with respect
            to such item; or
                (ii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, if the taxpayer can establish, based
            on a preponderance of the evidence, both of the
            following:
                    (a) the person during the same taxable
                year paid, accrued, or incurred, the
                intangible expense or cost to a person that is
                not a related member, and
                    (b) the transaction giving rise to the
                intangible expense or cost between the
                taxpayer and the person did not have as a
                principal purpose the avoidance of Illinois
                income tax, and is paid pursuant to a contract
                or agreement that reflects arm's-length terms;
                or
                (iii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person if the
            taxpayer establishes by clear and convincing
            evidence, that the adjustments are unreasonable;
            or if the taxpayer and the Director agree in
            writing to the application or use of an alternative
            method of apportionment under Section 304(f);
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (E-14) For taxable years ending on or after
        December 31, 2008, an amount equal to the amount of
        insurance premium expenses and costs otherwise allowed
        as a deduction in computing base income, and that were
        paid, accrued, or incurred, directly or indirectly, to
        a person who would be a member of the same unitary
        business group but for the fact that the person is
        prohibited under Section 1501(a)(27) from being
        included in the unitary business group because he or
        she is ordinarily required to apportion business
        income under different subsections of Section 304. The
        addition modification required by this subparagraph
        shall be reduced to the extent that dividends were
        included in base income of the unitary group for the
        same taxable year and received by the taxpayer or by a
        member of the taxpayer's unitary business group
        (including amounts included in gross income under
        Sections 951 through 964 of the Internal Revenue Code
        and amounts included in gross income under Section 78
        of the Internal Revenue Code) with respect to the stock
        of the same person to whom the premiums and costs were
        directly or indirectly paid, incurred, or accrued. The
        preceding sentence does not apply to the extent that
        the same dividends caused a reduction to the addition
        modification required under Section 203(b)(2)(E-12) or
        Section 203(b)(2)(E-13) of this Act;
            (E-15) For taxable years beginning after December
        31, 2008, any deduction for dividends paid by a captive
        real estate investment trust that is allowed to a real
        estate investment trust under Section 857(b)(2)(B) of
        the Internal Revenue Code for dividends paid;
            (E-16) An amount equal to the credit allowable to
        the taxpayer under Section 218(a) of this Act,
        determined without regard to Section 218(c) of this
        Act;
    and by deducting from the total so obtained the sum of the
    following amounts:
            (F) An amount equal to the amount of any tax
        imposed by this Act which was refunded to the taxpayer
        and included in such total for the taxable year;
            (G) An amount equal to any amount included in such
        total under Section 78 of the Internal Revenue Code;
            (H) In the case of a regulated investment company,
        an amount equal to the amount of exempt interest
        dividends as defined in subsection (b) (5) of Section
        852 of the Internal Revenue Code, paid to shareholders
        for the taxable year;
            (I) With the exception of any amounts subtracted
        under subparagraph (J), an amount equal to the sum of
        all amounts disallowed as deductions by (i) Sections
        171(a) (2), and 265(a)(2) and amounts disallowed as
        interest expense by Section 291(a)(3) of the Internal
        Revenue Code, as now or hereafter amended, and all
        amounts of expenses allocable to interest and
        disallowed as deductions by Section 265(a)(1) of the
        Internal Revenue Code, as now or hereafter amended; and
        (ii) for taxable years ending on or after August 13,
        1999, Sections 171(a)(2), 265, 280C, 291(a)(3), and
        832(b)(5)(B)(i) of the Internal Revenue Code, plus,
        for tax years ending on or after December 31, 2011,
        amounts disallowed as deductions by Section 45G(e)(3)
        of the Internal Revenue Code and, for taxable years
        ending on or after December 31, 2008, any amount
        included in gross income under Section 87 of the
        Internal Revenue Code and the policyholders' share of
        tax-exempt interest of a life insurance company under
        Section 807(a)(2)(B) of the Internal Revenue Code (in

        fact that the foreign person's business activity
        outside the United States is 80% or more of the foreign
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited

            with respect to such interest; or
                (ii) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer can establish, based on a
            preponderance of the evidence, both of the
            following:
                    (a) the person, during the same taxable
                year, paid, accrued, or incurred, the interest
                to a person that is not a related member, and
                    (b) the transaction giving rise to the
                interest expense between the taxpayer and the
                person did not have as a principal purpose the
                avoidance of Illinois income tax, and is paid
                pursuant to a contract or agreement that
                reflects an arm's-length interest rate and
                terms; or
                (iii) the taxpayer can establish, based on
            clear and convincing evidence, that the interest
            paid, accrued, or incurred relates to a contract or
            agreement entered into at arm's-length rates and
            terms and the principal purpose for the payment is
            not federal or Illinois tax avoidance; or
                (iv) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer establishes by clear and convincing
            evidence that the adjustments are unreasonable; or
            if the taxpayer and the Director agree in writing
            to the application or use of an alternative method
            of apportionment under Section 304(f).
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (G-13) An amount equal to the amount of intangible
        expenses and costs otherwise allowed as a deduction in
        computing base income, and that were paid, accrued, or
        incurred, directly or indirectly, (i) for taxable
        years ending on or after December 31, 2004, to a
        foreign person who would be a member of the same
        unitary business group but for the fact that the
        foreign person's business activity outside the United
        States is 80% or more of that person's total business
        activity and (ii) for taxable years ending on or after
        December 31, 2008, to a person who would be a member of
        the same unitary business group but for the fact that
        the person is prohibited under Section 1501(a)(27)
        from being included in the unitary business group
        because he or she is ordinarily required to apportion
        business income under different subsections of Section
        304. The addition modification required by this
        subparagraph shall be reduced to the extent that
        dividends were included in base income of the unitary
        group for the same taxable year and received by the
        taxpayer or by a member of the taxpayer's unitary
        business group (including amounts included in gross
        income pursuant to Sections 951 through 964 of the
        Internal Revenue Code and amounts included in gross
        income under Section 78 of the Internal Revenue Code)
        with respect to the stock of the same person to whom
        the intangible expenses and costs were directly or
        indirectly paid, incurred, or accrued. The preceding
        sentence shall not apply to the extent that the same
        dividends caused a reduction to the addition
        modification required under Section 203(c)(2)(G-12) of
        this Act. As used in this subparagraph, the term
        "intangible expenses and costs" includes: (1)
        expenses, losses, and costs for or related to the
        direct or indirect acquisition, use, maintenance or
        management, ownership, sale, exchange, or any other
        disposition of intangible property; (2) losses
        incurred, directly or indirectly, from factoring
        transactions or discounting transactions; (3) royalty,
        patent, technical, and copyright fees; (4) licensing
        fees; and (5) other similar expenses and costs. For
        purposes of this subparagraph, "intangible property"
        includes patents, patent applications, trade names,
        trademarks, service marks, copyrights, mask works,
        trade secrets, and similar types of intangible assets.
            This paragraph shall not apply to the following:
                (i) any item of intangible expenses or costs
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person who is
            subject in a foreign country or state, other than a
            state which requires mandatory unitary reporting,
            to a tax on or measured by net income with respect
            to such item; or
                (ii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, if the taxpayer can establish, based
            on a preponderance of the evidence, both of the
            following:
                    (a) the person during the same taxable
                year paid, accrued, or incurred, the
                intangible expense or cost to a person that is
                not a related member, and
                    (b) the transaction giving rise to the
                intangible expense or cost between the
                taxpayer and the person did not have as a
                principal purpose the avoidance of Illinois
                income tax, and is paid pursuant to a contract
                or agreement that reflects arm's-length terms;
                or
                (iii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person if the
            taxpayer establishes by clear and convincing
            evidence, that the adjustments are unreasonable;
            or if the taxpayer and the Director agree in
            writing to the application or use of an alternative
            method of apportionment under Section 304(f);
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (G-14) For taxable years ending on or after
        December 31, 2008, an amount equal to the amount of
        insurance premium expenses and costs otherwise allowed
        as a deduction in computing base income, and that were
        paid, accrued, or incurred, directly or indirectly, to
        a person who would be a member of the same unitary
        business group but for the fact that the person is
        prohibited under Section 1501(a)(27) from being
        included in the unitary business group because he or
        she is ordinarily required to apportion business
        income under different subsections of Section 304. The
        addition modification required by this subparagraph
        shall be reduced to the extent that dividends were
        included in base income of the unitary group for the
        same taxable year and received by the taxpayer or by a
        member of the taxpayer's unitary business group
        (including amounts included in gross income under
        Sections 951 through 964 of the Internal Revenue Code
        and amounts included in gross income under Section 78
        of the Internal Revenue Code) with respect to the stock
        of the same person to whom the premiums and costs were
        directly or indirectly paid, incurred, or accrued. The
        preceding sentence does not apply to the extent that
        the same dividends caused a reduction to the addition
        modification required under Section 203(c)(2)(G-12) or
        Section 203(c)(2)(G-13) of this Act;
            (G-15) An amount equal to the credit allowable to
        the taxpayer under Section 218(a) of this Act,
        determined without regard to Section 218(c) of this
        Act;
    and by deducting from the total so obtained the sum of the
    following amounts:
            (H) An amount equal to all amounts included in such
        total pursuant to the provisions of Sections 402(a),
        402(c), 403(a), 403(b), 406(a), 407(a) and 408 of the
        Internal Revenue Code or included in such total as
        distributions under the provisions of any retirement
        or disability plan for employees of any governmental
        agency or unit, or retirement payments to retired
        partners, which payments are excluded in computing net
        earnings from self employment by Section 1402 of the
        Internal Revenue Code and regulations adopted pursuant
        thereto;
            (I) The valuation limitation amount;
            (J) An amount equal to the amount of any tax
        imposed by this Act which was refunded to the taxpayer
        and included in such total for the taxable year;
            (K) An amount equal to all amounts included in
        taxable income as modified by subparagraphs (A), (B),
        (C), (D), (E), (F) and (G) which are exempt from
        taxation by this State either by reason of its statutes
        or Constitution or by reason of the Constitution,
        treaties or statutes of the United States; provided
        that, in the case of any statute of this State that
        exempts income derived from bonds or other obligations
        from the tax imposed under this Act, the amount
        exempted shall be the interest net of bond premium
        amortization;
            (L) With the exception of any amounts subtracted
        under subparagraph (K), an amount equal to the sum of
        all amounts disallowed as deductions by (i) Sections
        171(a) (2) and 265(a)(2) of the Internal Revenue Code,
        as now or hereafter amended, and all amounts of
        expenses allocable to interest and disallowed as
        deductions by Section 265(1) of the Internal Revenue
        Code of 1954, as now or hereafter amended; and (ii) for
        taxable years ending on or after August 13, 1999,
        Sections 171(a)(2), 265, 280C, and 832(b)(5)(B)(i) of
        the Internal Revenue Code, plus, (iii) for taxable
        years ending on or after December 31, 2011, Section
        45G(e)(3) of the Internal Revenue Code and, for taxable
        years ending on or after December 31, 2008, any amount
        included in gross income under Section 87 of the
        Internal Revenue Code; the provisions of this
        subparagraph are exempt from the provisions of Section
        250;
            (M) An amount equal to those dividends included in
        such total which were paid by a corporation which
        conducts business operations in an Enterprise Zone or
        zones created under the Illinois Enterprise Zone Act or
        a River Edge Redevelopment Zone or zones created under
        the River Edge Redevelopment Zone Act and conducts
        substantially all of its operations in an Enterprise
        Zone or Zones or a River Edge Redevelopment Zone or
        zones. This subparagraph (M) is exempt from the
        provisions of Section 250;
            (N) An amount equal to any contribution made to a
        job training project established pursuant to the Tax
        Increment Allocation Redevelopment Act;
            (O) An amount equal to those dividends included in
        such total that were paid by a corporation that
        conducts business operations in a federally designated
        Foreign Trade Zone or Sub-Zone and that is designated a
        High Impact Business located in Illinois; provided
        that dividends eligible for the deduction provided in
        subparagraph (M) of paragraph (2) of this subsection
        shall not be eligible for the deduction provided under
        this subparagraph (O);
            (P) An amount equal to the amount of the deduction
        used to compute the federal income tax credit for
        restoration of substantial amounts held under claim of
        right for the taxable year pursuant to Section 1341 of
        the Internal Revenue Code of 1986;
            (Q) For taxable year 1999 and thereafter, an amount
        equal to the amount of any (i) distributions, to the
        extent includible in gross income for federal income
        tax purposes, made to the taxpayer because of his or
        her status as a victim of persecution for racial or
        religious reasons by Nazi Germany or any other Axis
        regime or as an heir of the victim and (ii) items of
        income, to the extent includible in gross income for
        federal income tax purposes, attributable to, derived
        from or in any way related to assets stolen from,
        hidden from, or otherwise lost to a victim of
        persecution for racial or religious reasons by Nazi
        Germany or any other Axis regime immediately prior to,
        during, and immediately after World War II, including,
        but not limited to, interest on the proceeds receivable
        as insurance under policies issued to a victim of
        persecution for racial or religious reasons by Nazi
        Germany or any other Axis regime by European insurance
        companies immediately prior to and during World War II;
        provided, however, this subtraction from federal
        adjusted gross income does not apply to assets acquired
        with such assets or with the proceeds from the sale of
        such assets; provided, further, this paragraph shall
        only apply to a taxpayer who was the first recipient of
        such assets after their recovery and who is a victim of
        persecution for racial or religious reasons by Nazi
        Germany or any other Axis regime or as an heir of the
        victim. The amount of and the eligibility for any
        public assistance, benefit, or similar entitlement is
        not affected by the inclusion of items (i) and (ii) of
        this paragraph in gross income for federal income tax
        purposes. This paragraph is exempt from the provisions
        of Section 250;
            (R) For taxable years 2001 and thereafter, for the
        taxable year in which the bonus depreciation deduction
        is taken on the taxpayer's federal income tax return
        under subsection (k) of Section 168 of the Internal
        Revenue Code and for each applicable taxable year
        thereafter, an amount equal to "x", where:
                (1) "y" equals the amount of the depreciation
            deduction taken for the taxable year on the
            taxpayer's federal income tax return on property
            for which the bonus depreciation deduction was
            taken in any year under subsection (k) of Section
            168 of the Internal Revenue Code, but not including
            the bonus depreciation deduction;
                (2) for taxable years ending on or before
            December 31, 2005, "x" equals "y" multiplied by 30
            and then divided by 70 (or "y" multiplied by
            0.429); and
                (3) for taxable years ending after December
            31, 2005:
                    (i) for property on which a bonus
                depreciation deduction of 30% of the adjusted

                0.429); and
                    (ii) for property on which a bonus
                depreciation deduction of 50% of the adjusted
                basis was taken, "x" equals "y" multiplied by
                1.0.
            The aggregate amount deducted under this
        subparagraph in all taxable years for any one piece of
        property may not exceed the amount of the bonus
        depreciation deduction taken on that property on the
        taxpayer's federal income tax return under subsection
        (k) of Section 168 of the Internal Revenue Code. This
        subparagraph (R) is exempt from the provisions of
        Section 250;
            (S) If the taxpayer sells, transfers, abandons, or
        otherwise disposes of property for which the taxpayer
        was required in any taxable year to make an addition
        modification under subparagraph (G-10), then an amount
        equal to that addition modification.
            If the taxpayer continues to own property through
        the last day of the last tax year for which the
        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was required in any taxable year to make an addition
        modification under subparagraph (G-10), then an amount
        equal to that addition modification.
            The taxpayer is allowed to take the deduction under
        this subparagraph only once with respect to any one
        piece of property.
            This subparagraph (S) is exempt from the
        provisions of Section 250;
            (T) The amount of (i) any interest income (net of
        the deductions allocable thereto) taken into account
        for the taxable year with respect to a transaction with
        a taxpayer that is required to make an addition
        modification with respect to such transaction under
        Section 203(a)(2)(D-17), 203(b)(2)(E-12),
        203(c)(2)(G-12), or 203(d)(2)(D-7), but not to exceed
        the amount of such addition modification and (ii) any
        income from intangible property (net of the deductions
        allocable thereto) taken into account for the taxable
        year with respect to a transaction with a taxpayer that

        into account for the taxable year (net of the
        deductions allocable thereto) with respect to

        member of the taxpayer's unitary business group but for
        the fact the foreign person's business activity
        outside the United States is 80% or more of that
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304, but not to exceed the
        addition modification required to be made for the same
        taxable year under Section 203(c)(2)(G-12) for
        interest paid, accrued, or incurred, directly or
        indirectly, to the same person. This subparagraph (U)
        is exempt from the provisions of Section 250; and
            (V) An amount equal to the income from intangible
        property taken into account for the taxable year (net
        of the deductions allocable thereto) with respect to
        transactions with (i) a foreign person who would be a
        member of the taxpayer's unitary business group but for
        the fact that the foreign person's business activity
        outside the United States is 80% or more of that
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304, but not to exceed the
        addition modification required to be made for the same
        taxable year under Section 203(c)(2)(G-13) for
        intangible expenses and costs paid, accrued, or
        incurred, directly or indirectly, to the same foreign
        person. This subparagraph (V) is exempt from the
        provisions of Section 250; .
            (W) in the case of an estate, an amount equal to
        all amounts included in such total pursuant to the
        provisions of Section 111 of the Internal Revenue Code
        as a recovery of items previously deducted by the
        decedent from adjusted gross income in the computation
        of taxable income. This subparagraph (W) is exempt from
        Section 250;
            (X) an amount equal to the refund included in such
        total of any tax deducted for federal income tax
        purposes, to the extent that deduction was added back
        under subparagraph (F). This subparagraph (X) is
        exempt from the provisions of Section 250; and
            (Y) For taxable years ending on or after December
        31, 2011, in the case of a taxpayer who was required to
        add back any insurance premiums under Section

        that part of a reimbursement received from the
        insurance company equal to the amount of the expense or
        loss (including expenses incurred by the insurance
        company) that would have been taken into account as a
        deduction for federal income tax purposes if the
        expense or loss had been uninsured. If a taxpayer makes
        the election provided for by this subparagraph (Y), the
        insurer to which the premiums were paid must add back
        to income the amount subtracted by the taxpayer
        pursuant to this subparagraph (Y). This subparagraph
        (Y) is exempt from the provisions of Section 250.
        (3) Limitation. The amount of any modification
    otherwise required under this subsection shall, under
    regulations prescribed by the Department, be adjusted by
    any amounts included therein which were properly paid,
    credited, or required to be distributed, or permanently set
    aside for charitable purposes pursuant to Internal Revenue
    Code Section 642(c) during the taxable year.
 
    (d) Partnerships.
        (1) In general. In the case of a partnership, base
    income means an amount equal to the taxpayer's taxable
    income for the taxable year as modified by paragraph (2).
        (2) Modifications. The taxable income referred to in
    paragraph (1) shall be modified by adding thereto the sum
    of the following amounts:
            (A) An amount equal to all amounts paid or accrued
        to the taxpayer as interest or dividends during the
        taxable year to the extent excluded from gross income
        in the computation of taxable income;
            (B) An amount equal to the amount of tax imposed by
        this Act to the extent deducted from gross income for
        the taxable year;
            (C) The amount of deductions allowed to the
        partnership pursuant to Section 707 (c) of the Internal
        Revenue Code in calculating its taxable income;
            (D) An amount equal to the amount of the capital

        Code, to the extent deducted from gross income in the
        computation of taxable income;
            (D-5) For taxable years 2001 and thereafter, an
        amount equal to the bonus depreciation deduction taken
        on the taxpayer's federal income tax return for the
        taxable year under subsection (k) of Section 168 of the
        Internal Revenue Code;
            (D-6) If the taxpayer sells, transfers, abandons,
        or otherwise disposes of property for which the
        taxpayer was required in any taxable year to make an
        addition modification under subparagraph (D-5), then
        an amount equal to the aggregate amount of the
        deductions taken in all taxable years under
        subparagraph (O) with respect to that property.
            If the taxpayer continues to own property through
        the last day of the last tax year for which the
        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was allowed in any taxable year to make a subtraction
        modification under subparagraph (O), then an amount
        equal to that subtraction modification.
            The taxpayer is required to make the addition
        modification under this subparagraph only once with
        respect to any one piece of property;
            (D-7) An amount equal to the amount otherwise
        allowed as a deduction in computing base income for
        interest paid, accrued, or incurred, directly or
        indirectly, (i) for taxable years ending on or after
        December 31, 2004, to a foreign person who would be a
        member of the same unitary business group but for the
        fact the foreign person's business activity outside
        the United States is 80% or more of the foreign
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304. The addition modification
        required by this subparagraph shall be reduced to the
        extent that dividends were included in base income of
        the unitary group for the same taxable year and
        received by the taxpayer or by a member of the
        taxpayer's unitary business group (including amounts
        included in gross income pursuant to Sections 951
        through 964 of the Internal Revenue Code and amounts
        included in gross income under Section 78 of the
        Internal Revenue Code) with respect to the stock of the
        same person to whom the interest was paid, accrued, or
        incurred.
            This paragraph shall not apply to the following:
                (i) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person who
            is subject in a foreign country or state, other
            than a state which requires mandatory unitary
            reporting, to a tax on or measured by net income
            with respect to such interest; or
                (ii) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer can establish, based on a
            preponderance of the evidence, both of the
            following:
                    (a) the person, during the same taxable
                year, paid, accrued, or incurred, the interest
                to a person that is not a related member, and
                    (b) the transaction giving rise to the
                interest expense between the taxpayer and the
                person did not have as a principal purpose the
                avoidance of Illinois income tax, and is paid
                pursuant to a contract or agreement that
                reflects an arm's-length interest rate and
                terms; or
                (iii) the taxpayer can establish, based on
            clear and convincing evidence, that the interest
            paid, accrued, or incurred relates to a contract or
            agreement entered into at arm's-length rates and
            terms and the principal purpose for the payment is
            not federal or Illinois tax avoidance; or
                (iv) an item of interest paid, accrued, or
            incurred, directly or indirectly, to a person if
            the taxpayer establishes by clear and convincing
            evidence that the adjustments are unreasonable; or
            if the taxpayer and the Director agree in writing
            to the application or use of an alternative method
            of apportionment under Section 304(f).
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act; and
            (D-8) An amount equal to the amount of intangible
        expenses and costs otherwise allowed as a deduction in
        computing base income, and that were paid, accrued, or
        incurred, directly or indirectly, (i) for taxable
        years ending on or after December 31, 2004, to a
        foreign person who would be a member of the same
        unitary business group but for the fact that the
        foreign person's business activity outside the United
        States is 80% or more of that person's total business
        activity and (ii) for taxable years ending on or after
        December 31, 2008, to a person who would be a member of
        the same unitary business group but for the fact that
        the person is prohibited under Section 1501(a)(27)
        from being included in the unitary business group
        because he or she is ordinarily required to apportion
        business income under different subsections of Section
        304. The addition modification required by this
        subparagraph shall be reduced to the extent that
        dividends were included in base income of the unitary
        group for the same taxable year and received by the
        taxpayer or by a member of the taxpayer's unitary
        business group (including amounts included in gross
        income pursuant to Sections 951 through 964 of the
        Internal Revenue Code and amounts included in gross
        income under Section 78 of the Internal Revenue Code)
        with respect to the stock of the same person to whom
        the intangible expenses and costs were directly or
        indirectly paid, incurred or accrued. The preceding
        sentence shall not apply to the extent that the same
        dividends caused a reduction to the addition
        modification required under Section 203(d)(2)(D-7) of
        this Act. As used in this subparagraph, the term
        "intangible expenses and costs" includes (1) expenses,
        losses, and costs for, or related to, the direct or
        indirect acquisition, use, maintenance or management,
        ownership, sale, exchange, or any other disposition of
        intangible property; (2) losses incurred, directly or
        indirectly, from factoring transactions or discounting
        transactions; (3) royalty, patent, technical, and
        copyright fees; (4) licensing fees; and (5) other
        similar expenses and costs. For purposes of this
        subparagraph, "intangible property" includes patents,
        patent applications, trade names, trademarks, service
        marks, copyrights, mask works, trade secrets, and
        similar types of intangible assets;
            This paragraph shall not apply to the following:
                (i) any item of intangible expenses or costs
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person who is
            subject in a foreign country or state, other than a
            state which requires mandatory unitary reporting,
            to a tax on or measured by net income with respect
            to such item; or
                (ii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, if the taxpayer can establish, based
            on a preponderance of the evidence, both of the
            following:
                    (a) the person during the same taxable
                year paid, accrued, or incurred, the
                intangible expense or cost to a person that is
                not a related member, and
                    (b) the transaction giving rise to the
                intangible expense or cost between the
                taxpayer and the person did not have as a
                principal purpose the avoidance of Illinois
                income tax, and is paid pursuant to a contract
                or agreement that reflects arm's-length terms;
                or
                (iii) any item of intangible expense or cost
            paid, accrued, or incurred, directly or
            indirectly, from a transaction with a person if the
            taxpayer establishes by clear and convincing
            evidence, that the adjustments are unreasonable;
            or if the taxpayer and the Director agree in
            writing to the application or use of an alternative
            method of apportionment under Section 304(f);
                Nothing in this subsection shall preclude the
            Director from making any other adjustment
            otherwise allowed under Section 404 of this Act for
            any tax year beginning after the effective date of
            this amendment provided such adjustment is made
            pursuant to regulation adopted by the Department
            and such regulations provide methods and standards
            by which the Department will utilize its authority
            under Section 404 of this Act;
            (D-9) For taxable years ending on or after December
        31, 2008, an amount equal to the amount of insurance
        premium expenses and costs otherwise allowed as a
        deduction in computing base income, and that were paid,
        accrued, or incurred, directly or indirectly, to a
        person who would be a member of the same unitary
        business group but for the fact that the person is
        prohibited under Section 1501(a)(27) from being
        included in the unitary business group because he or
        she is ordinarily required to apportion business
        income under different subsections of Section 304. The
        addition modification required by this subparagraph
        shall be reduced to the extent that dividends were
        included in base income of the unitary group for the
        same taxable year and received by the taxpayer or by a
        member of the taxpayer's unitary business group
        (including amounts included in gross income under
        Sections 951 through 964 of the Internal Revenue Code
        and amounts included in gross income under Section 78
        of the Internal Revenue Code) with respect to the stock
        of the same person to whom the premiums and costs were
        directly or indirectly paid, incurred, or accrued. The
        preceding sentence does not apply to the extent that
        the same dividends caused a reduction to the addition
        modification required under Section 203(d)(2)(D-7) or
        Section 203(d)(2)(D-8) of this Act;
            (D-10) An amount equal to the credit allowable to
        the taxpayer under Section 218(a) of this Act,
        determined without regard to Section 218(c) of this
        Act;
    and by deducting from the total so obtained the following
    amounts:
            (E) The valuation limitation amount;
            (F) An amount equal to the amount of any tax
        imposed by this Act which was refunded to the taxpayer
        and included in such total for the taxable year;
            (G) An amount equal to all amounts included in
        taxable income as modified by subparagraphs (A), (B),
        (C) and (D) which are exempt from taxation by this
        State either by reason of its statutes or Constitution
        or by reason of the Constitution, treaties or statutes
        of the United States; provided that, in the case of any
        statute of this State that exempts income derived from
        bonds or other obligations from the tax imposed under
        this Act, the amount exempted shall be the interest net
        of bond premium amortization;
            (H) Any income of the partnership which
        constitutes personal service income as defined in
        Section 1348 (b) (1) of the Internal Revenue Code (as
        in effect December 31, 1981) or a reasonable allowance
        for compensation paid or accrued for services rendered
        by partners to the partnership, whichever is greater;
        this subparagraph (H) is exempt from the provisions of
        Section 250;
            (I) An amount equal to all amounts of income
        distributable to an entity subject to the Personal
        Property Tax Replacement Income Tax imposed by
        subsections (c) and (d) of Section 201 of this Act
        including amounts distributable to organizations
        exempt from federal income tax by reason of Section
        501(a) of the Internal Revenue Code; this subparagraph
        (I) is exempt from the provisions of Section 250;
            (J) With the exception of any amounts subtracted
        under subparagraph (G), an amount equal to the sum of
        all amounts disallowed as deductions by (i) Sections
        171(a) (2), and 265(2) of the Internal Revenue Code of
        1954, as now or hereafter amended, and all amounts of
        expenses allocable to interest and disallowed as
        deductions by Section 265(1) of the Internal Revenue
        Code, as now or hereafter amended; and (ii) for taxable
        years ending on or after August 13, 1999, Sections
        171(a)(2), 265, 280C, and 832(b)(5)(B)(i) of the
        Internal Revenue Code, plus, (iii) for taxable years
        ending on or after December 31, 2011, Section 45G(e)(3)
        of the Internal Revenue Code and, for taxable years
        ending on or after December 31, 2008, any amount
        included in gross income under Section 87 of the
        Internal Revenue Code; the provisions of this
        subparagraph are exempt from the provisions of Section
        250;
            (K) An amount equal to those dividends included in
        such total which were paid by a corporation which
        conducts business operations in an Enterprise Zone or
        zones created under the Illinois Enterprise Zone Act,
        enacted by the 82nd General Assembly, or a River Edge
        Redevelopment Zone or zones created under the River
        Edge Redevelopment Zone Act and conducts substantially
        all of its operations in an Enterprise Zone or Zones or
        from a River Edge Redevelopment Zone or zones. This
        subparagraph (K) is exempt from the provisions of
        Section 250;
            (L) An amount equal to any contribution made to a
        job training project established pursuant to the Real
        Property Tax Increment Allocation Redevelopment Act;
            (M) An amount equal to those dividends included in
        such total that were paid by a corporation that
        conducts business operations in a federally designated
        Foreign Trade Zone or Sub-Zone and that is designated a
        High Impact Business located in Illinois; provided
        that dividends eligible for the deduction provided in
        subparagraph (K) of paragraph (2) of this subsection
        shall not be eligible for the deduction provided under
        this subparagraph (M);
            (N) An amount equal to the amount of the deduction
        used to compute the federal income tax credit for
        restoration of substantial amounts held under claim of
        right for the taxable year pursuant to Section 1341 of
        the Internal Revenue Code of 1986;
            (O) For taxable years 2001 and thereafter, for the
        taxable year in which the bonus depreciation deduction
        is taken on the taxpayer's federal income tax return
        under subsection (k) of Section 168 of the Internal
        Revenue Code and for each applicable taxable year
        thereafter, an amount equal to "x", where:
                (1) "y" equals the amount of the depreciation
            deduction taken for the taxable year on the
            taxpayer's federal income tax return on property
            for which the bonus depreciation deduction was
            taken in any year under subsection (k) of Section
            168 of the Internal Revenue Code, but not including
            the bonus depreciation deduction;
                (2) for taxable years ending on or before
            December 31, 2005, "x" equals "y" multiplied by 30
            and then divided by 70 (or "y" multiplied by
            0.429); and
                (3) for taxable years ending after December
            31, 2005:
                    (i) for property on which a bonus
                depreciation deduction of 30% of the adjusted
                basis was taken, "x" equals "y" multiplied by
                30 and then divided by 70 (or "y" multiplied by
                0.429); and
                    (ii) for property on which a bonus
                depreciation deduction of 50% of the adjusted
                basis was taken, "x" equals "y" multiplied by
                1.0.
            The aggregate amount deducted under this
        subparagraph in all taxable years for any one piece of
        property may not exceed the amount of the bonus
        depreciation deduction taken on that property on the
        taxpayer's federal income tax return under subsection
        (k) of Section 168 of the Internal Revenue Code. This
        subparagraph (O) is exempt from the provisions of
        Section 250;
            (P) If the taxpayer sells, transfers, abandons, or
        otherwise disposes of property for which the taxpayer
        was required in any taxable year to make an addition
        modification under subparagraph (D-5), then an amount
        equal to that addition modification.
            If the taxpayer continues to own property through
        the last day of the last tax year for which the
        taxpayer may claim a depreciation deduction for
        federal income tax purposes and for which the taxpayer
        was required in any taxable year to make an addition
        modification under subparagraph (D-5), then an amount
        equal to that addition modification.
            The taxpayer is allowed to take the deduction under
        this subparagraph only once with respect to any one
        piece of property.
            This subparagraph (P) is exempt from the
        provisions of Section 250;
            (Q) The amount of (i) any interest income (net of
        the deductions allocable thereto) taken into account
        for the taxable year with respect to a transaction with
        a taxpayer that is required to make an addition
        modification with respect to such transaction under
        Section 203(a)(2)(D-17), 203(b)(2)(E-12),
        203(c)(2)(G-12), or 203(d)(2)(D-7), but not to exceed
        the amount of such addition modification and (ii) any
        income from intangible property (net of the deductions
        allocable thereto) taken into account for the taxable
        year with respect to a transaction with a taxpayer that
        is required to make an addition modification with
        respect to such transaction under Section
        203(a)(2)(D-18), 203(b)(2)(E-13), 203(c)(2)(G-13), or
        203(d)(2)(D-8), but not to exceed the amount of such
        addition modification. This subparagraph (Q) is exempt
        from Section 250;
            (R) An amount equal to the interest income taken
        into account for the taxable year (net of the
        deductions allocable thereto) with respect to
        transactions with (i) a foreign person who would be a
        member of the taxpayer's unitary business group but for
        the fact that the foreign person's business activity
        outside the United States is 80% or more of that
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304, but not to exceed the
        addition modification required to be made for the same
        taxable year under Section 203(d)(2)(D-7) for interest
        paid, accrued, or incurred, directly or indirectly, to
        the same person. This subparagraph (R) is exempt from
        Section 250; and
            (S) An amount equal to the income from intangible

        outside the United States is 80% or more of that
        person's total business activity and (ii) for taxable
        years ending on or after December 31, 2008, to a person
        who would be a member of the same unitary business
        group but for the fact that the person is prohibited
        under Section 1501(a)(27) from being included in the
        unitary business group because he or she is ordinarily
        required to apportion business income under different
        subsections of Section 304, but not to exceed the
        addition modification required to be made for the same
        taxable year under Section 203(d)(2)(D-8) for
        intangible expenses and costs paid, accrued, or
        incurred, directly or indirectly, to the same person.
        This subparagraph (S) is exempt from Section 250; and .
            (T) For taxable years ending on or after December
        31, 2011, in the case of a taxpayer who was required to

        that part of a reimbursement received from the
        insurance company equal to the amount of the expense or
        loss (including expenses incurred by the insurance
        company) that would have been taken into account as a
        deduction for federal income tax purposes if the
        expense or loss had been uninsured. If a taxpayer makes
        the election provided for by this subparagraph (T), the
        insurer to which the premiums were paid must add back
        to income the amount subtracted by the taxpayer
        pursuant to this subparagraph (T). This subparagraph
        (T) is exempt from the provisions of Section 250.
 
    (e) Gross income; adjusted gross income; taxable income.
        (1) In general. Subject to the provisions of paragraph
    (2) and subsection (b) (3), for purposes of this Section
    and Section 803(e), a taxpayer's gross income, adjusted
    gross income, or taxable income for the taxable year shall
    mean the amount of gross income, adjusted gross income or
    taxable income properly reportable for federal income tax
    purposes for the taxable year under the provisions of the
    Internal Revenue Code. Taxable income may be less than
    zero. However, for taxable years ending on or after
    December 31, 1986, net operating loss carryforwards from
    taxable years ending prior to December 31, 1986, may not
    exceed the sum of federal taxable income for the taxable
    year before net operating loss deduction, plus the excess
    of addition modifications over subtraction modifications
    for the taxable year. For taxable years ending prior to
    December 31, 1986, taxable income may never be an amount in
    excess of the net operating loss for the taxable year as
    defined in subsections (c) and (d) of Section 172 of the
    Internal Revenue Code, provided that when taxable income of
    a corporation (other than a Subchapter S corporation),
    trust, or estate is less than zero and addition
    modifications, other than those provided by subparagraph
    (E) of paragraph (2) of subsection (b) for corporations or
    subparagraph (E) of paragraph (2) of subsection (c) for
    trusts and estates, exceed subtraction modifications, an
    addition modification must be made under those
    subparagraphs for any other taxable year to which the
    taxable income less than zero (net operating loss) is
    applied under Section 172 of the Internal Revenue Code or
    under subparagraph (E) of paragraph (2) of this subsection
    (e) applied in conjunction with Section 172 of the Internal
    Revenue Code.
        (2) Special rule. For purposes of paragraph (1) of this
    subsection, the taxable income properly reportable for
    federal income tax purposes shall mean:
            (A) Certain life insurance companies. In the case
        of a life insurance company subject to the tax imposed
        by Section 801 of the Internal Revenue Code, life
        insurance company taxable income, plus the amount of
        distribution from pre-1984 policyholder surplus
        accounts as calculated under Section 815a of the
        Internal Revenue Code;
            (B) Certain other insurance companies. In the case
        of mutual insurance companies subject to the tax
        imposed by Section 831 of the Internal Revenue Code,
        insurance company taxable income;
            (C) Regulated investment companies. In the case of
        a regulated investment company subject to the tax
        imposed by Section 852 of the Internal Revenue Code,
        investment company taxable income;
            (D) Real estate investment trusts. In the case of a
        real estate investment trust subject to the tax imposed
        by Section 857 of the Internal Revenue Code, real
        estate investment trust taxable income;
            (E) Consolidated corporations. In the case of a
        corporation which is a member of an affiliated group of
        corporations filing a consolidated income tax return
        for the taxable year for federal income tax purposes,
        taxable income determined as if such corporation had
        filed a separate return for federal income tax purposes
        for the taxable year and each preceding taxable year
        for which it was a member of an affiliated group. For
        purposes of this subparagraph, the taxpayer's separate
        taxable income shall be determined as if the election
        provided by Section 243(b) (2) of the Internal Revenue
        Code had been in effect for all such years;
            (F) Cooperatives. In the case of a cooperative
        corporation or association, the taxable income of such
        organization determined in accordance with the
        provisions of Section 1381 through 1388 of the Internal
        Revenue Code, but without regard to the prohibition
        against offsetting losses from patronage activities
        against income from nonpatronage activities; except
        that a cooperative corporation or association may make
        an election to follow its federal income tax treatment
        of patronage losses and nonpatronage losses. In the
        event such election is made, such losses shall be
        computed and carried over in a manner consistent with
        subsection (a) of Section 207 of this Act and
        apportioned by the apportionment factor reported by
        the cooperative on its Illinois income tax return filed
        for the taxable year in which the losses are incurred.
        The election shall be effective for all taxable years
        with original returns due on or after the date of the
        election. In addition, the cooperative may file an
        amended return or returns, as allowed under this Act,
        to provide that the election shall be effective for
        losses incurred or carried forward for taxable years
        occurring prior to the date of the election. Once made,
        the election may only be revoked upon approval of the
        Director. The Department shall adopt rules setting
        forth requirements for documenting the elections and
        any resulting Illinois net loss and the standards to be
        used by the Director in evaluating requests to revoke
        elections. Public Act 96-932 This amendatory Act of the
        96th General Assembly is declaratory of existing law;
            (G) Subchapter S corporations. In the case of: (i)
        a Subchapter S corporation for which there is in effect
        an election for the taxable year under Section 1362 of
        the Internal Revenue Code, the taxable income of such
        corporation determined in accordance with Section
        1363(b) of the Internal Revenue Code, except that
        taxable income shall take into account those items
        which are required by Section 1363(b)(1) of the
        Internal Revenue Code to be separately stated; and (ii)
        a Subchapter S corporation for which there is in effect
        a federal election to opt out of the provisions of the
        Subchapter S Revision Act of 1982 and have applied
        instead the prior federal Subchapter S rules as in
        effect on July 1, 1982, the taxable income of such
        corporation determined in accordance with the federal
        Subchapter S rules as in effect on July 1, 1982; and
            (H) Partnerships. In the case of a partnership,
        taxable income determined in accordance with Section
        703 of the Internal Revenue Code, except that taxable
        income shall take into account those items which are
        required by Section 703(a)(1) to be separately stated
        but which would be taken into account by an individual
        in calculating his taxable income.
        (3) Recapture of business expenses on disposition of
    asset or business. Notwithstanding any other law to the
    contrary, if in prior years income from an asset or
    business has been classified as business income and in a
    later year is demonstrated to be non-business income, then
    all expenses, without limitation, deducted in such later
    year and in the 2 immediately preceding taxable years
    related to that asset or business that generated the
    non-business income shall be added back and recaptured as
    business income in the year of the disposition of the asset
    or business. Such amount shall be apportioned to Illinois
    using the greater of the apportionment fraction computed
    for the business under Section 304 of this Act for the
    taxable year or the average of the apportionment fractions
    computed for the business under Section 304 of this Act for
    the taxable year and for the 2 immediately preceding
    taxable years.
 
    (f) Valuation limitation amount.
        (1) In general. The valuation limitation amount
    referred to in subsections (a) (2) (G), (c) (2) (I) and
    (d)(2) (E) is an amount equal to:
            (A) The sum of the pre-August 1, 1969 appreciation
        amounts (to the extent consisting of gain reportable
        under the provisions of Section 1245 or 1250 of the
        Internal Revenue Code) for all property in respect of
        which such gain was reported for the taxable year; plus
            (B) The lesser of (i) the sum of the pre-August 1,
        1969 appreciation amounts (to the extent consisting of
        capital gain) for all property in respect of which such
        gain was reported for federal income tax purposes for
        the taxable year, or (ii) the net capital gain for the
        taxable year, reduced in either case by any amount of
        such gain included in the amount determined under
        subsection (a) (2) (F) or (c) (2) (H).
        (2) Pre-August 1, 1969 appreciation amount.
            (A) If the fair market value of property referred
        to in paragraph (1) was readily ascertainable on August
        1, 1969, the pre-August 1, 1969 appreciation amount for
        such property is the lesser of (i) the excess of such
        fair market value over the taxpayer's basis (for
        determining gain) for such property on that date
        (determined under the Internal Revenue Code as in
        effect on that date), or (ii) the total gain realized
        and reportable for federal income tax purposes in
        respect of the sale, exchange or other disposition of
        such property.
            (B) If the fair market value of property referred
        to in paragraph (1) was not readily ascertainable on
        August 1, 1969, the pre-August 1, 1969 appreciation
        amount for such property is that amount which bears the
        same ratio to the total gain reported in respect of the
        property for federal income tax purposes for the
        taxable year, as the number of full calendar months in
        that part of the taxpayer's holding period for the
        property ending July 31, 1969 bears to the number of
        full calendar months in the taxpayer's entire holding
        period for the property.
            (C) The Department shall prescribe such
        regulations as may be necessary to carry out the
        purposes of this paragraph.
 
    (g) Double deductions. Unless specifically provided
otherwise, nothing in this Section shall permit the same item
to be deducted more than once.
 
    (h) Legislative intention. Except as expressly provided by
this Section there shall be no modifications or limitations on
the amounts of income, gain, loss or deduction taken into
account in determining gross income, adjusted gross income or
taxable income for federal income tax purposes for the taxable
year, or in the amount of such items entering into the
computation of base income and net income under this Act for
such taxable year, whether in respect of property values as of
August 1, 1969 or otherwise.

    Sec. 204. Standard Exemption.
    (a) Allowance of exemption. In computing net income under
this Act, there shall be allowed as an exemption the sum of the
amounts determined under subsections (b), (c) and (d),
multiplied by a fraction the numerator of which is the amount
of the taxpayer's base income allocable to this State for the
taxable year and the denominator of which is the taxpayer's
total base income for the taxable year.
    (b) Basic amount. For the purpose of subsection (a) of this
Section, except as provided by subsection (a) of Section 205
and in this subsection, each taxpayer shall be allowed a basic
amount of $1000, except that for corporations the basic amount
shall be zero for tax years ending on or after December 31,
2003, and for individuals the basic amount shall be:
        (1) for taxable years ending on or after December 31,
    1998 and prior to December 31, 1999, $1,300;

    1999 and prior to December 31, 2000, $1,650;
        (3) for taxable years ending on or after December 31,

For taxable years ending on or after December 31, 1992, a
taxpayer whose Illinois base income exceeds the basic amount
and who is claimed as a dependent on another person's tax
return under the Internal Revenue Code of 1986 shall not be
allowed any basic amount under this subsection.
    (c) Additional amount for individuals. In the case of an

        additional exemption of $1,000 for the spouse of the
        taxpayer if a joint return is not made by the taxpayer
        and his spouse, and if the spouse has attained the age
        of 65 before the end of such taxable year, and, for the
        calendar year in which the taxable year of the taxpayer
        begins, has no gross income and is not the dependent of
        another taxpayer.

        and if the spouse is blind and, for the calendar year
        in which the taxable year of the taxpayer begins, has
        no gross income and is not the dependent of another
        taxpayer. For purposes of this paragraph, the
        determination of whether the spouse is blind shall be
        made as of the end of the taxable year of the taxpayer;
        except that if the spouse dies during such taxable year
        such determination shall be made as of the time of such
        death.

        subsection, an individual is blind only if his or her
        central visual acuity does not exceed 20/200 in the
        better eye with correcting lenses, or if his or her
        visual acuity is greater than 20/200 but is accompanied
        by a limitation in the fields of vision such that the

    (35 ILCS 5/207)  (from Ch. 120, par. 2-207)
    Sec. 207. Net Losses.
    (a) If after applying all of the (i) modifications provided
for in paragraph (2) of Section 203(b), paragraph (2) of
Section 203(c) and paragraph (2) of Section 203(d) and (ii) the
allocation and apportionment provisions of Article 3 of this
Act and subsection (c) of this Section, the taxpayer's net
income results in a loss;
        (1) for any taxable year ending prior to December 31,
    1999, such loss shall be allowed as a carryover or
    carryback deduction in the manner allowed under Section 172
    of the Internal Revenue Code;
        (2) for any taxable year ending on or after December
    31, 1999 and prior to December 31, 2003, such loss shall be
    allowed as a carryback to each of the 2 taxable years
    preceding the taxable year of such loss and shall be a net
    operating loss carryover to each of the 20 taxable years
    following the taxable year of such loss; and
        (3) for any taxable year ending on or after December
    31, 2003, such loss shall be allowed as a net operating
    loss carryover to each of the 12 taxable years following
    the taxable year of such loss, except as provided in
    subsection (d).
    (a-5) Election to relinquish carryback and order of
application of losses.
            (A) For losses incurred in tax years ending prior
        to December 31, 2003, the taxpayer may elect to
        relinquish the entire carryback period with respect to
        such loss. Such election shall be made in the form and
        manner prescribed by the Department and shall be made
        by the due date (including extensions of time) for
        filing the taxpayer's return for the taxable year in
        which such loss is incurred, and such election, once
        made, shall be irrevocable.
            (B) The entire amount of such loss shall be carried
        to the earliest taxable year to which such loss may be
        carried. The amount of such loss which shall be carried
        to each of the other taxable years shall be the excess,
        if any, of the amount of such loss over the sum of the
        deductions for carryback or carryover of such loss
        allowable for each of the prior taxable years to which
        such loss may be carried.
    (b) Any loss determined under subsection (a) of this
Section must be carried back or carried forward in the same
manner for purposes of subsections (a) and (b) of Section 201
of this Act as for purposes of subsections (c) and (d) of
Section 201 of this Act.
    (c) Notwithstanding any other provision of this Act, for
each taxable year ending on or after December 31, 2008, for
purposes of computing the loss for the taxable year under
subsection (a) of this Section and the deduction taken into
account for the taxable year for a net operating loss carryover
under paragraphs (1), (2), and (3) of subsection (a) of this
Section, the loss and net operating loss carryover shall be
reduced in an amount equal to the reduction to the net
operating loss and net operating loss carryover to the taxable
year, respectively, required under Section 108(b)(2)(A) of the
Internal Revenue Code, multiplied by a fraction, the numerator
of which is the amount of discharge of indebtedness income that
is excluded from gross income for the taxable year (but only if
the taxable year ends on or after December 31, 2008) under
Section 108(a) of the Internal Revenue Code and that would have
been allocated and apportioned to this State under Article 3 of
this Act but for that exclusion, and the denominator of which
is the total amount of discharge of indebtedness income
excluded from gross income under Section 108(a) of the Internal
Revenue Code for the taxable year. The reduction required under
this subsection (c) shall be made after the determination of
Illinois net income for the taxable year in which the
indebtedness is discharged.
    (d) In the case of a corporation (other than a Subchapter S
corporation), no carryover deduction shall be allowed under
this Section for any taxable year ending after December 31,
2010 and prior to December 31, 2014; provided that, for
purposes of determining the taxable years to which a net loss
may be carried under subsection (a) of this Section, no taxable
year for which a deduction is disallowed under this subsection
shall be counted.
    (e) In the case of a residual interest holder in a real
estate mortgage investment conduit subject to Section 860E of
the Internal Revenue Code, the net loss in subsection (a) shall
be equal to:
        (1) the amount computed under subsection (a), without
    regard to this subsection (e), or if that amount is
    positive, zero;
        (2) minus an amount equal to the amount computed under
    subsection (a), without regard to this subsection (e),
    minus the amount that would be computed under subsection
    (a) if the taxpayer's federal taxable income were computed
    without regard to Section 860E of the Internal Revenue Code
    and without regard to this subsection (e).
    The modification in this subsection (e) is exempt from the
provisions of Section 250.

against the tax imposed by subsections (a) and (b) of Section
201 in an amount equal to 50% of the value of the donation.
Partners, shareholders of subchapter S corporations, and
owners of limited liability companies (if the limited liability
company is treated as a partnership for purposes of federal and
State income taxation) are entitled to a credit under this
Section to be determined in accordance with the determination
of income and distributive share of income under Sections 702
and 703 and subchapter S of the Internal Revenue Code. Persons

and (b) of Section 201 and who make a donation under Section
7.28 of the Illinois Housing Development Act are entitled to a
credit as described in this subsection and may transfer that
credit as described in subsection (c).
    (b) If the amount of the credit exceeds the tax liability
for the year, the excess may be carried forward and applied to
the tax liability of the 5 taxable years following the excess
credit year. The tax credit shall be applied to the earliest
year for which there is a tax liability. If there are credits
for more than one year that are available to offset a
liability, the earlier credit shall be applied first.
    (c) The transfer of the tax credit allowed under this
Section may be made (i) to the purchaser of land that has been
designated solely for affordable housing projects in
accordance with the Illinois Housing Development Act or (ii) to
another donor who has also made a donation in accordance with
Section 7.28 of the Illinois Housing Development Act.
    (d) A taxpayer claiming the credit provided by this Section
must maintain and record any information that the Department
may require by regulation regarding the project for which the
credit is claimed. When claiming the credit provided by this
Section, the taxpayer must provide information regarding the
taxpayer's donation to the project under the Illinois Housing
Development Act.

    (35 ILCS 5/304)  (from Ch. 120, par. 3-304)
    Sec. 304. Business income of persons other than residents.
    (a) In general. The business income of a person other than
a resident shall be allocated to this State if such person's
business income is derived solely from this State. If a person
other than a resident derives business income from this State
and one or more other states, then, for tax years ending on or
before December 30, 1998, and except as otherwise provided by
this Section, such person's business income shall be
apportioned to this State by multiplying the income by a
fraction, the numerator of which is the sum of the property
factor (if any), the payroll factor (if any) and 200% of the
sales factor (if any), and the denominator of which is 4
reduced by the number of factors other than the sales factor
which have a denominator of zero and by an additional 2 if the
sales factor has a denominator of zero. For tax years ending on
or after December 31, 1998, and except as otherwise provided by
this Section, persons other than residents who derive business
income from this State and one or more other states shall
compute their apportionment factor by weighting their
property, payroll, and sales factors as provided in subsection
(h) of this Section.
    (1) Property factor.
        (A) The property factor is a fraction, the numerator of
    which is the average value of the person's real and
    tangible personal property owned or rented and used in the
    trade or business in this State during the taxable year and
    the denominator of which is the average value of all the
    person's real and tangible personal property owned or
    rented and used in the trade or business during the taxable
    year.
        (B) Property owned by the person is valued at its
    original cost. Property rented by the person is valued at 8
    times the net annual rental rate. Net annual rental rate is
    the annual rental rate paid by the person less any annual
    rental rate received by the person from sub-rentals.
        (C) The average value of property shall be determined
    by averaging the values at the beginning and ending of the
    taxable year but the Director may require the averaging of
    monthly values during the taxable year if reasonably
    required to reflect properly the average value of the
    person's property.
    (2) Payroll factor.
        (A) The payroll factor is a fraction, the numerator of
    which is the total amount paid in this State during the
    taxable year by the person for compensation, and the
    denominator of which is the total compensation paid
    everywhere during the taxable year.
        (B) Compensation is paid in this State if:
            (i) The individual's service is performed entirely
        within this State;
            (ii) The individual's service is performed both
        within and without this State, but the service
        performed without this State is incidental to the
        individual's service performed within this State; or
            (iii) Some of the service is performed within this
        State and either the base of operations, or if there is
        no base of operations, the place from which the service
        is directed or controlled is within this State, or the
        base of operations or the place from which the service
        is directed or controlled is not in any state in which
        some part of the service is performed, but the
        individual's residence is in this State.
            (iv) Compensation paid to nonresident professional
        athletes.
            (a) General. The Illinois source income of a
        nonresident individual who is a member of a
        professional athletic team includes the portion of the
        individual's total compensation for services performed
        as a member of a professional athletic team during the
        taxable year which the number of duty days spent within
        this State performing services for the team in any
        manner during the taxable year bears to the total
        number of duty days spent both within and without this
        State during the taxable year.
            (b) Travel days. Travel days that do not involve
        either a game, practice, team meeting, or other similar
        team event are not considered duty days spent in this
        State. However, such travel days are considered in the
        total duty days spent both within and without this
        State.
            (c) Definitions. For purposes of this subpart
        (iv):
                (1) The term "professional athletic team"
            includes, but is not limited to, any professional
            baseball, basketball, football, soccer, or hockey
            team.
                (2) The term "member of a professional
            athletic team" includes those employees who are
            active players, players on the disabled list, and
            any other persons required to travel and who travel
            with and perform services on behalf of a
            professional athletic team on a regular basis.
            This includes, but is not limited to, coaches,
            managers, and trainers.
                (3) Except as provided in items (C) and (D) of
            this subpart (3), the term "duty days" means all
            days during the taxable year from the beginning of
            the professional athletic team's official
            pre-season training period through the last game
            in which the team competes or is scheduled to
            compete. Duty days shall be counted for the year in
            which they occur, including where a team's
            official pre-season training period through the
            last game in which the team competes or is
            scheduled to compete, occurs during more than one
            tax year.
                    (A) Duty days shall also include days on
                which a member of a professional athletic team
                performs service for a team on a date that does
                not fall within the foregoing period (e.g.,
                participation in instructional leagues, the
                "All Star Game", or promotional "caravans").
                Performing a service for a professional
                athletic team includes conducting training and
                rehabilitation activities, when such
                activities are conducted at team facilities.
                    (B) Also included in duty days are game
                days, practice days, days spent at team
                meetings, promotional caravans, preseason
                training camps, and days served with the team
                through all post-season games in which the team
                competes or is scheduled to compete.
                    (C) Duty days for any person who joins a
                team during the period from the beginning of
                the professional athletic team's official
                pre-season training period through the last
                game in which the team competes, or is
                scheduled to compete, shall begin on the day
                that person joins the team. Conversely, duty
                days for any person who leaves a team during
                this period shall end on the day that person
                leaves the team. Where a person switches teams
                during a taxable year, a separate duty-day
                calculation shall be made for the period the
                person was with each team.
                    (D) Days for which a member of a
                professional athletic team is not compensated
                and is not performing services for the team in
                any manner, including days when such member of
                a professional athletic team has been
                suspended without pay and prohibited from
                performing any services for the team, shall not
                be treated as duty days.
                    (E) Days for which a member of a
                professional athletic team is on the disabled
                list and does not conduct rehabilitation
                activities at facilities of the team, and is
                not otherwise performing services for the team
                in Illinois, shall not be considered duty days
                spent in this State. All days on the disabled
                list, however, are considered to be included in
                total duty days spent both within and without
                this State.
                (4) The term "total compensation for services
            performed as a member of a professional athletic
            team" means the total compensation received during
            the taxable year for services performed:
                    (A) from the beginning of the official
                pre-season training period through the last
                game in which the team competes or is scheduled
                to compete during that taxable year; and
                    (B) during the taxable year on a date which
                does not fall within the foregoing period
                (e.g., participation in instructional leagues,
                the "All Star Game", or promotional caravans).
                This compensation shall include, but is not
            limited to, salaries, wages, bonuses as described
            in this subpart, and any other type of compensation
            paid during the taxable year to a member of a
            professional athletic team for services performed
            in that year. This compensation does not include
            strike benefits, severance pay, termination pay,
            contract or option year buy-out payments,
            expansion or relocation payments, or any other
            payments not related to services performed for the
            team.
                For purposes of this subparagraph, "bonuses"
            included in "total compensation for services
            performed as a member of a professional athletic
            team" subject to the allocation described in
            Section 302(c)(1) are: bonuses earned as a result
            of play (i.e., performance bonuses) during the
            season, including bonuses paid for championship,
            playoff or "bowl" games played by a team, or for
            selection to all-star league or other honorary
            positions; and bonuses paid for signing a
            contract, unless the payment of the signing bonus
            is not conditional upon the signee playing any
            games for the team or performing any subsequent
            services for the team or even making the team, the
            signing bonus is payable separately from the
            salary and any other compensation, and the signing
            bonus is nonrefundable.

        government or the person is not taxable in the state of
        the purchaser; provided, however, that premises owned
        or leased by a person who has independently contracted
        with the seller for the printing of newspapers,
        periodicals or books shall not be deemed to be an
        office, store, warehouse, factory or other place of
        storage for purposes of this Section. Sales of tangible
        personal property are not in this State if the seller
        and purchaser would be members of the same unitary
        business group but for the fact that either the seller
        or purchaser is a person with 80% or more of total

            extent that it is employed in production,
            fabrication, manufacturing, or other processing in

            is produced in the state. If a patent is utilized
            in more than one state, the extent to which it is
            utilized in any one state shall be a fraction equal
            to the gross receipts of the licensee or purchaser
            from sales or leases of items produced,
            fabricated, manufactured, or processed within that
            state using the patent and of patented items
            produced within that state, divided by the total of
            such gross receipts for all states in which the
            patent is utilized.
                (II) A copyright is utilized in a state to the
            extent that printing or other publication
            originates in the state. If a copyright is utilized
            in more than one state, the extent to which it is
            utilized in any one state shall be a fraction equal
            to the gross receipts from sales or licenses of
            materials printed or published in that state
            divided by the total of such gross receipts for all
            states in which the copyright is utilized.
                (III) Trademarks and other items of intangible
            personal property governed by this paragraph (B-1)
            are utilized in the state in which the commercial

            (iii) If the state of utilization of an item of
        property governed by this paragraph (B-1) cannot be
        determined from the taxpayer's books and records or
        from the books and records of any person related to the
        taxpayer within the meaning of Section 267(b) of the
        Internal Revenue Code, 26 U.S.C. 267, the gross

        sales factor.
        (B-2) Gross receipts from the license, sale, or other
    disposition of patents, copyrights, trademarks, and
    similar items of intangible personal property, other than
    gross receipts governed by paragraph (B-7) of this item
    (3), may be included in the numerator or denominator of the
    sales factor only if gross receipts from licenses, sales,
    or other disposition of such items comprise more than 50%
    of the taxpayer's total gross receipts included in gross
    income during the tax year and during each of the 2
    immediately preceding tax years; provided that, when a
    taxpayer is a member of a unitary business group, such
    determination shall be made on the basis of the gross
    receipts of the entire unitary business group.

        audience or subscribers located in this State of a
        station, a network, or a cable system bears to the

        or radio programming shall be determined by reference
        to the books and records of the taxpayer or by
        reference to published rating statistics provided the
        method used by the taxpayer is consistently used from

        taxpayer's activity in this State.
            "Broadcast" or "broadcasting" or "broadcasting
        services" means the transmission or provision of film
        or radio programming, whether through the public

            "Film" or "film programming" means the broadcast
        on television of any and all performances, events, or
        productions, including but not limited to news,
        sporting events, plays, stories, or other literary,

        series relates to the same principal subject and is
        produced during one or more tax periods.
            "Radio" or "radio programming" means the broadcast
        on radio of any and all performances, events, or
        productions, including but not limited to news,
        sporting events, plays, stories, or other literary,
        commercial, educational, or artistic works, either

        radio programming produced for radio broadcast shall
        constitute a separate "radio programming"

        tax periods.
                (i) In the case of advertising revenue from
            broadcasting, the customer is the advertiser and
            the service is received in this State if the
            commercial domicile of the advertiser is in this
            State.
                (ii) In the case where film or radio
            programming is broadcast by a station, a network,
            or a cable system for a fee or other remuneration
            received from the recipient of the broadcast, the
            portion of the service that is received in this
            State is measured by the portion of the recipients
            of the broadcast located in this State.
            Accordingly, the fee or other remuneration for
            such service that is included in the Illinois
            numerator of the sales factor is the total of those
            fees or other remuneration received from
            recipients in Illinois. For purposes of this
            paragraph, a taxpayer may determine the location
            of the recipients of its broadcast using the
            address of the recipient shown in its contracts
            with the recipient or using the billing address of
            the recipient in the taxpayer's records.
                (iii) In the case where film or radio
            programming is broadcast by a station, a network,

            from the person providing the programming, the
            portion of the broadcast service that is received
            by such station, network, or cable system in this
            State is measured by the portion of recipients of
            the broadcast located in this State. Accordingly,
            the amount of revenue related to such an
            arrangement that is included in the Illinois
            numerator of the sales factor is the total fee or
            other total remuneration from the person providing
            the programming related to that broadcast
            multiplied by the Illinois audience factor for
            that broadcast.
                (iv) In the case where film or radio

            customer the broadcasting service is received at
            the location of the office of the customer from
            which the services were ordered in the regular
            course of the customer's trade or business.
            Accordingly, in such a case the revenue derived by
            the taxpayer that is included in the taxpayer's
            Illinois numerator of the sales factor is the
            revenue from such customers who receive the
            broadcasting service in Illinois.
                (v) In the case where film or radio programming
            is provided by a taxpayer that is not a network or
            station to another person for broadcasting in
            exchange for a fee or other remuneration from that
            person, the broadcasting service is received at
            the location of the office of the customer from
            which the services were ordered in the regular
            course of the customer's trade or business.
            Accordingly, in such a case the revenue derived by
            the taxpayer that is included in the taxpayer's
            Illinois numerator of the sales factor is the
            revenue from such customers who receive the
            broadcasting service in Illinois.

    2008, sales, other than sales governed by paragraphs (B),

        are in this State if the property is located in this
        State.

        less than zero) and other items of income from
        intangible personal property, the sale is in this State
        if:
                (a) in the case of a taxpayer who is a dealer
            in the item of intangible personal property within
            the meaning of Section 475 of the Internal Revenue
            Code, the income or gain is received from a
            customer in this State. For purposes of this
            subparagraph, a customer is in this State if the
            customer is an individual, trust or estate who is a
            resident of this State and, for all other
            customers, if the customer's commercial domicile
            is in this State. Unless the dealer has actual
            knowledge of the residence or commercial domicile
            of a customer during a taxable year, the customer
            shall be deemed to be a customer in this State if
            the billing address of the customer, as shown in
            the records of the dealer, is in this State; or
                (b) in all other cases, if the
            income-producing activity of the taxpayer is
            performed in this State or, if the
            income-producing activity of the taxpayer is
            performed both within and without this State, if a
            greater proportion of the income-producing
            activity of the taxpayer is performed within this
            State than in any other state, based on performance
            costs.
            (iv) Sales of services are in this State if the
        services are received in this State. For the purposes
        of this section, gross receipts from the performance of
        services provided to a corporation, partnership, or
        trust may only be attributed to a state where that
        corporation, partnership, or trust has a fixed place of
        business. If the state where the services are received
        is not readily determinable or is a state where the
        corporation, partnership, or trust receiving the
        service does not have a fixed place of business, the
        services shall be deemed to be received at the location
        of the office of the customer from which the services
        were ordered in the regular course of the customer's
        trade or business. If the ordering office cannot be
        determined, the services shall be deemed to be received
        at the office of the customer to which the services are
        billed. If the taxpayer is not taxable in the state in
        which the services are received, the sale must be
        excluded from both the numerator and the denominator of
        the sales factor. The Department shall adopt rules
        prescribing where specific types of service are
        received, including, but not limited to, publishing,
        and utility service.
        (D) For taxable years ending on or after December 31,
    1995, the following items of income shall not be included
    in the numerator or denominator of the sales factor:
    dividends; amounts included under Section 78 of the
    Internal Revenue Code; and Subpart F income as defined in
    Section 952 of the Internal Revenue Code. No inference
    shall be drawn from the enactment of this paragraph (D) in
    construing this Section for taxable years ending before
    December 31, 1995.
        (E) Paragraphs (B-1) and (B-2) shall apply to tax years
    ending on or after December 31, 1999, provided that a
    taxpayer may elect to apply the provisions of these
    paragraphs to prior tax years. Such election shall be made
    in the form and manner prescribed by the Department, shall
    be irrevocable, and shall apply to all tax years; provided
    that, if a taxpayer's Illinois income tax liability for any
    tax year, as assessed under Section 903 prior to January 1,
    1999, was computed in a manner contrary to the provisions
    of paragraphs (B-1) or (B-2), no refund shall be payable to
    the taxpayer for that tax year to the extent such refund is
    the result of applying the provisions of paragraph (B-1) or
    (B-2) retroactively. In the case of a unitary business
    group, such election shall apply to all members of such
    group for every tax year such group is in existence, but
    shall not apply to any taxpayer for any period during which
    that taxpayer is not a member of such group.
    (b) Insurance companies.
        (1) In general. Except as otherwise provided by
    paragraph (2), business income of an insurance company for
    a taxable year shall be apportioned to this State by
    multiplying such income by a fraction, the numerator of
    which is the direct premiums written for insurance upon
    property or risk in this State, and the denominator of
    which is the direct premiums written for insurance upon
    property or risk everywhere. For purposes of this
    subsection, the term "direct premiums written" means the
    total amount of direct premiums written, assessments and
    annuity considerations as reported for the taxable year on
    the annual statement filed by the company with the Illinois
    Director of Insurance in the form approved by the National
    Convention of Insurance Commissioners or such other form as
    may be prescribed in lieu thereof.
        (2) Reinsurance. If the principal source of premiums
    written by an insurance company consists of premiums for
    reinsurance accepted by it, the business income of such
    company shall be apportioned to this State by multiplying
    such income by a fraction, the numerator of which is the
    sum of (i) direct premiums written for insurance upon
    property or risk in this State, plus (ii) premiums written
    for reinsurance accepted in respect of property or risk in
    this State, and the denominator of which is the sum of
    (iii) direct premiums written for insurance upon property
    or risk everywhere, plus (iv) premiums written for
    reinsurance accepted in respect of property or risk
    everywhere. For taxable years ending before December 31,
    2008, for purposes of this paragraph, premiums written for
    reinsurance accepted in respect of property or risk in this
    State, whether or not otherwise determinable, may, at the
    election of the company, be determined on the basis of the
    proportion which premiums written for reinsurance accepted
    from companies commercially domiciled in Illinois bears to
    premiums written for reinsurance accepted from all
    sources, or, alternatively, in the proportion which the sum
    of the direct premiums written for insurance upon property
    or risk in this State by each ceding company from which
    reinsurance is accepted bears to the sum of the total
    direct premiums written by each such ceding company for the
    taxable year. The election made by a company under this
    paragraph for its first taxable year ending on or after
    December 31, 2011, shall be binding for that company for
    that taxable year and for all subsequent taxable years, and
    may be altered only with the written permission of the
    Department, which shall not be unreasonably withheld.
    (c) Financial organizations.
        (1) In general. For taxable years ending before
    December 31, 2008, business income of a financial
    organization shall be apportioned to this State by
    multiplying such income by a fraction, the numerator of
    which is its business income from sources within this
    State, and the denominator of which is its business income
    from all sources. For the purposes of this subsection, the
    business income of a financial organization from sources
    within this State is the sum of the amounts referred to in
    subparagraphs (A) through (E) following, but excluding the
    adjusted income of an international banking facility as
    determined in paragraph (2):
            (A) Fees, commissions or other compensation for
        financial services rendered within this State;
            (B) Gross profits from trading in stocks, bonds or
        other securities managed within this State;
            (C) Dividends, and interest from Illinois
        customers, which are received within this State;
            (D) Interest charged to customers at places of
        business maintained within this State for carrying
        debit balances of margin accounts, without deduction
        of any costs incurred in carrying such accounts; and
            (E) Any other gross income resulting from the
        operation as a financial organization within this
        State. In computing the amounts referred to in
        paragraphs (A) through (E) of this subsection, any
        amount received by a member of an affiliated group
        (determined under Section 1504(a) of the Internal
        Revenue Code but without reference to whether any such
        corporation is an "includible corporation" under
        Section 1504(b) of the Internal Revenue Code) from
        another member of such group shall be included only to
        the extent such amount exceeds expenses of the
        recipient directly related thereto.
        (2) International Banking Facility. For taxable years
    ending before December 31, 2008:
            (A) Adjusted Income. The adjusted income of an
        international banking facility is its income reduced
        by the amount of the floor amount.
            (B) Floor Amount. The floor amount shall be the
        amount, if any, determined by multiplying the income of
        the international banking facility by a fraction, not
        greater than one, which is determined as follows:
                (i) The numerator shall be:
                The average aggregate, determined on a
            quarterly basis, of the financial organization's
            loans to banks in foreign countries, to foreign
            domiciled borrowers (except where secured
            primarily by real estate) and to foreign
            governments and other foreign official
            institutions, as reported for its branches,
            agencies and offices within the state on its
            "Consolidated Report of Condition", Schedule A,
            Lines 2.c., 5.b., and 7.a., which was filed with
            the Federal Deposit Insurance Corporation and
            other regulatory authorities, for the year 1980,
            minus
                The average aggregate, determined on a
            quarterly basis, of such loans (other than loans of
            an international banking facility), as reported by
            the financial institution for its branches,
            agencies and offices within the state, on the
            corresponding Schedule and lines of the
            Consolidated Report of Condition for the current
            taxable year, provided, however, that in no case
            shall the amount determined in this clause (the
            subtrahend) exceed the amount determined in the
            preceding clause (the minuend); and
                (ii) the denominator shall be the average
            aggregate, determined on a quarterly basis, of the
            international banking facility's loans to banks in
            foreign countries, to foreign domiciled borrowers
            (except where secured primarily by real estate)
            and to foreign governments and other foreign
            official institutions, which were recorded in its
            financial accounts for the current taxable year.
            (C) Change to Consolidated Report of Condition and
        in Qualification. In the event the Consolidated Report
        of Condition which is filed with the Federal Deposit
        Insurance Corporation and other regulatory authorities
        is altered so that the information required for
        determining the floor amount is not found on Schedule
        A, lines 2.c., 5.b. and 7.a., the financial institution
        shall notify the Department and the Department may, by
        regulations or otherwise, prescribe or authorize the
        use of an alternative source for such information. The
        financial institution shall also notify the Department
        should its international banking facility fail to
        qualify as such, in whole or in part, or should there
        be any amendment or change to the Consolidated Report
        of Condition, as originally filed, to the extent such
        amendment or change alters the information used in
        determining the floor amount.
        (3) For taxable years ending on or after December 31,
    2008, the business income of a financial organization shall
    be apportioned to this State by multiplying such income by
    a fraction, the numerator of which is its gross receipts
    from sources in this State or otherwise attributable to
    this State's marketplace and the denominator of which is
    its gross receipts everywhere during the taxable year.
    "Gross receipts" for purposes of this subparagraph (3)
    means gross income, including net taxable gain on
    disposition of assets, including securities and money
    market instruments, when derived from transactions and
    activities in the regular course of the financial
    organization's trade or business. The following examples
    are illustrative:
            (i) Receipts from the lease or rental of real or
        tangible personal property are in this State if the
        property is located in this State during the rental
        period. Receipts from the lease or rental of tangible
        personal property that is characteristically moving
        property, including, but not limited to, motor
        vehicles, rolling stock, aircraft, vessels, or mobile
        equipment are from sources in this State to the extent
        that the property is used in this State.
            (ii) Interest income, commissions, fees, gains on
        disposition, and other receipts from assets in the
        nature of loans that are secured primarily by real
        estate or tangible personal property are from sources
        in this State if the security is located in this State.
            (iii) Interest income, commissions, fees, gains on
        disposition, and other receipts from consumer loans
        that are not secured by real or tangible personal
        property are from sources in this State if the debtor
        is a resident of this State.
            (iv) Interest income, commissions, fees, gains on
        disposition, and other receipts from commercial loans
        and installment obligations that are not secured by
        real or tangible personal property are from sources in
        this State if the proceeds of the loan are to be
        applied in this State. If it cannot be determined where
        the funds are to be applied, the income and receipts
        are from sources in this State if the office of the
        borrower from which the loan was negotiated in the
        regular course of business is located in this State. If
        the location of this office cannot be determined, the
        income and receipts shall be excluded from the
        numerator and denominator of the sales factor.
            (v) Interest income, fees, gains on disposition,
        service charges, merchant discount income, and other
        receipts from credit card receivables are from sources
        in this State if the card charges are regularly billed
        to a customer in this State.
            (vi) Receipts from the performance of services,
        including, but not limited to, fiduciary, advisory,
        and brokerage services, are in this State if the
        services are received in this State within the meaning
        of subparagraph (a)(3)(C-5)(iv) of this Section.
            (vii) Receipts from the issuance of travelers
        checks and money orders are from sources in this State
        if the checks and money orders are issued from a
        location within this State.
            (viii) Receipts from investment assets and
        activities and trading assets and activities are
        included in the receipts factor as follows:
                (1) Interest, dividends, net gains (but not
            less than zero) and other income from investment
            assets and activities from trading assets and
            activities shall be included in the receipts
            factor. Investment assets and activities and
            trading assets and activities include but are not
            limited to: investment securities; trading account
            assets; federal funds; securities purchased and
            sold under agreements to resell or repurchase;
            options; futures contracts; forward contracts;
            notional principal contracts such as swaps;
            equities; and foreign currency transactions. With
            respect to the investment and trading assets and
            activities described in subparagraphs (A) and (B)
            of this paragraph, the receipts factor shall
            include the amounts described in such
            subparagraphs.
                    (A) The receipts factor shall include the
                amount by which interest from federal funds
                sold and securities purchased under resale
                agreements exceeds interest expense on federal
                funds purchased and securities sold under
                repurchase agreements.
                    (B) The receipts factor shall include the
                amount by which interest, dividends, gains and
                other income from trading assets and
                activities, including but not limited to
                assets and activities in the matched book, in
                the arbitrage book, and foreign currency
                transactions, exceed amounts paid in lieu of
                interest, amounts paid in lieu of dividends,
                and losses from such assets and activities.
                (2) The numerator of the receipts factor
            includes interest, dividends, net gains (but not
            less than zero), and other income from investment
            assets and activities and from trading assets and
            activities described in paragraph (1) of this
            subsection that are attributable to this State.
                    (A) The amount of interest, dividends, net
                gains (but not less than zero), and other
                income from investment assets and activities
                in the investment account to be attributed to
                this State and included in the numerator is
                determined by multiplying all such income from
                such assets and activities by a fraction, the
                numerator of which is the gross income from
                such assets and activities which are properly
                assigned to a fixed place of business of the
                taxpayer within this State and the denominator
                of which is the gross income from all such
                assets and activities.
                    (B) The amount of interest from federal
                funds sold and purchased and from securities
                purchased under resale agreements and
                securities sold under repurchase agreements
                attributable to this State and included in the
                numerator is determined by multiplying the
                amount described in subparagraph (A) of
                paragraph (1) of this subsection from such
                funds and such securities by a fraction, the
                numerator of which is the gross income from
                such funds and such securities which are
                properly assigned to a fixed place of business
                of the taxpayer within this State and the
                denominator of which is the gross income from
                all such funds and such securities.
                    (C) The amount of interest, dividends,
                gains, and other income from trading assets and
                activities, including but not limited to
                assets and activities in the matched book, in
                the arbitrage book and foreign currency
                transactions (but excluding amounts described
                in subparagraphs (A) or (B) of this paragraph),
                attributable to this State and included in the
                numerator is determined by multiplying the
                amount described in subparagraph (B) of
                paragraph (1) of this subsection by a fraction,
                the numerator of which is the gross income from
                such trading assets and activities which are
                properly assigned to a fixed place of business
                of the taxpayer within this State and the
                denominator of which is the gross income from
                all such assets and activities.
                    (D) Properly assigned, for purposes of
                this paragraph (2) of this subsection, means
                the investment or trading asset or activity is
                assigned to the fixed place of business with
                which it has a preponderance of substantive
                contacts. An investment or trading asset or
                activity assigned by the taxpayer to a fixed
                place of business without the State shall be
                presumed to have been properly assigned if:
                        (i) the taxpayer has assigned, in the
                    regular course of its business, such asset
                    or activity on its records to a fixed place
                    of business consistent with federal or
                    state regulatory requirements;
                        (ii) such assignment on its records is
                    based upon substantive contacts of the
                    asset or activity to such fixed place of
                    business; and
                        (iii) the taxpayer uses such records
                    reflecting assignment of such assets or
                    activities for the filing of all state and
                    local tax returns for which an assignment
                    of such assets or activities to a fixed
                    place of business is required.
                    (E) The presumption of proper assignment
                of an investment or trading asset or activity
                provided in subparagraph (D) of paragraph (2)
                of this subsection may be rebutted upon a
                showing by the Department, supported by a
                preponderance of the evidence, that the
                preponderance of substantive contacts
                regarding such asset or activity did not occur
                at the fixed place of business to which it was
                assigned on the taxpayer's records. If the
                fixed place of business that has a
                preponderance of substantive contacts cannot
                be determined for an investment or trading
                asset or activity to which the presumption in
                subparagraph (D) of paragraph (2) of this
                subsection does not apply or with respect to
                which that presumption has been rebutted, that
                asset or activity is properly assigned to the
                state in which the taxpayer's commercial
                domicile is located. For purposes of this
                subparagraph (E), it shall be presumed,
                subject to rebuttal, that taxpayer's
                commercial domicile is in the state of the
                United States or the District of Columbia to
                which the greatest number of employees are
                regularly connected with the management of the
                investment or trading income or out of which
                they are working, irrespective of where the
                services of such employees are performed, as of
                the last day of the taxable year.
        (4) (Blank).
        (5) (Blank).
    (d) Transportation services. For taxable years ending
before December 31, 2008, business income derived from
furnishing transportation services shall be apportioned to
this State in accordance with paragraphs (1) and (2):
        (1) Such business income (other than that derived from
    transportation by pipeline) shall be apportioned to this
    State by multiplying such income by a fraction, the
    numerator of which is the revenue miles of the person in
    this State, and the denominator of which is the revenue
    miles of the person everywhere. For purposes of this
    paragraph, a revenue mile is the transportation of 1
    passenger or 1 net ton of freight the distance of 1 mile
    for a consideration. Where a person is engaged in the
    transportation of both passengers and freight, the
    fraction above referred to shall be determined by means of
    an average of the passenger revenue mile fraction and the
    freight revenue mile fraction, weighted to reflect the
    person's
            (A) relative railway operating income from total
        passenger and total freight service, as reported to the
        Interstate Commerce Commission, in the case of
        transportation by railroad, and
            (B) relative gross receipts from passenger and
        freight transportation, in case of transportation
        other than by railroad.
        (2) Such business income derived from transportation
    by pipeline shall be apportioned to this State by
    multiplying such income by a fraction, the numerator of
    which is the revenue miles of the person in this State, and
    the denominator of which is the revenue miles of the person
    everywhere. For the purposes of this paragraph, a revenue
    mile is the transportation by pipeline of 1 barrel of oil,
    1,000 cubic feet of gas, or of any specified quantity of
    any other substance, the distance of 1 mile for a
    consideration.
        (3) For taxable years ending on or after December 31,
    2008, business income derived from providing
    transportation services other than airline services shall
    be apportioned to this State by using a fraction, (a) the
    numerator of which shall be (i) all receipts from any
    movement or shipment of people, goods, mail, oil, gas, or
    any other substance (other than by airline) that both
    originates and terminates in this State, plus (ii) that
    portion of the person's gross receipts from movements or
    shipments of people, goods, mail, oil, gas, or any other
    substance (other than by airline) that originates in one
    state or jurisdiction and terminates in another state or
    jurisdiction, that is determined by the ratio that the
    miles traveled in this State bears to total miles
    everywhere and (b) the denominator of which shall be all
    revenue derived from the movement or shipment of people,
    goods, mail, oil, gas, or any other substance (other than
    by airline). Where a taxpayer is engaged in the
    transportation of both passengers and freight, the
    fraction above referred to shall first be determined
    separately for passenger miles and freight miles. Then an
    average of the passenger miles fraction and the freight
    miles fraction shall be weighted to reflect the taxpayer's:
            (A) relative railway operating income from total
        passenger and total freight service, as reported to the
        Surface Transportation Board, in the case of
        transportation by railroad; and
            (B) relative gross receipts from passenger and
        freight transportation, in case of transportation
        other than by railroad.
        (4) For taxable years ending on or after December 31,
    2008, business income derived from furnishing airline
    transportation services shall be apportioned to this State
    by multiplying such income by a fraction, the numerator of
    which is the revenue miles of the person in this State, and
    the denominator of which is the revenue miles of the person
    everywhere. For purposes of this paragraph, a revenue mile
    is the transportation of one passenger or one net ton of
    freight the distance of one mile for a consideration. If a
    person is engaged in the transportation of both passengers
    and freight, the fraction above referred to shall be
    determined by means of an average of the passenger revenue
    mile fraction and the freight revenue mile fraction,
    weighted to reflect the person's relative gross receipts
    from passenger and freight airline transportation.
    (e) Combined apportionment. Where 2 or more persons are
engaged in a unitary business as described in subsection
(a)(27) of Section 1501, a part of which is conducted in this
State by one or more members of the group, the business income
attributable to this State by any such member or members shall
be apportioned by means of the combined apportionment method.
    (f) Alternative allocation. If the allocation and
apportionment provisions of subsections (a) through (e) and of
subsection (h) do not fairly represent the extent of a person's
business activity in this State, the person may petition for,
or the Director may, without a petition, permit or require, in
respect of all or any part of the person's business activity,
if reasonable:
        (1) Separate accounting;
        (2) The exclusion of any one or more factors;
        (3) The inclusion of one or more additional factors
    which will fairly represent the person's business
    activities in this State; or
        (4) The employment of any other method to effectuate an
    equitable allocation and apportionment of the person's
    business income.
    (g) Cross reference. For allocation of business income by
residents, see Section 301(a).
    (h) For tax years ending on or after December 31, 1998, the
apportionment factor of persons who apportion their business
income to this State under subsection (a) shall be equal to:
        (1) for tax years ending on or after December 31, 1998
    and before December 31, 1999, 16 2/3% of the property
    factor plus 16 2/3% of the payroll factor plus 66 2/3% of
    the sales factor;
        (2) for tax years ending on or after December 31, 1999
    and before December 31, 2000, 8 1/3% of the property factor
    plus 8 1/3% of the payroll factor plus 83 1/3% of the sales
    factor;
        (3) for tax years ending on or after December 31, 2000,
    the sales factor.
If, in any tax year ending on or after December 31, 1998 and
before December 31, 2000, the denominator of the payroll,
property, or sales factor is zero, the apportionment factor
computed in paragraph (1) or (2) of this subsection for that
year shall be divided by an amount equal to 100% minus the

    (35 ILCS 5/502)  (from Ch. 120, par. 5-502)
    Sec. 502. Returns and notices.
    (a) In general. A return with respect to the taxes imposed
by this Act shall be made by every person for any taxable year:
        (1) for which such person is liable for a tax imposed
    by this Act, or
        (2) in the case of a resident or in the case of a
    corporation which is qualified to do business in this
    State, for which such person is required to make a federal
    income tax return, regardless of whether such person is
    liable for a tax imposed by this Act. However, this
    paragraph shall not require a resident to make a return if
    such person has an Illinois base income of the basic amount
    in Section 204(b) or less and is either claimed as a
    dependent on another person's tax return under the Internal
    Revenue Code of 1986, or is claimed as a dependent on
    another person's tax return under this Act.
    Notwithstanding the provisions of paragraph (1), a
nonresident (other than, for taxable years ending on or after
December 31, 2011, a nonresident required to withhold tax under
Section 709.5) whose Illinois income tax liability under
subsections (a), (b), (c), and (d) of Section 201 of this Act
is paid in full after taking into account the credits allowed
under subsection (f) of this Section or allowed under Section
709.5 of this Act shall not be required to file a return under
this subsection (a).
    (b) Fiduciaries and receivers.
        (1) Decedents. If an individual is deceased, any return
    or notice required of such individual under this Act shall
    be made by his executor, administrator, or other person
    charged with the property of such decedent.
        (2) Individuals under a disability. If an individual is
    unable to make a return or notice required under this Act,
    the return or notice required of such individual shall be
    made by his duly authorized agent, guardian, fiduciary or
    other person charged with the care of the person or
    property of such individual.
        (3) Estates and trusts. Returns or notices required of
    an estate or a trust shall be made by the fiduciary
    thereof.
        (4) Receivers, trustees and assignees for
    corporations. In a case where a receiver, trustee in
    bankruptcy, or assignee, by order of a court of competent
    jurisdiction, by operation of law, or otherwise, has
    possession of or holds title to all or substantially all
    the property or business of a corporation, whether or not
    such property or business is being operated, such receiver,
    trustee, or assignee shall make the returns and notices
    required of such corporation in the same manner and form as
    corporations are required to make such returns and notices.
    (c) Joint returns by husband and wife.
        (1) Except as provided in paragraph (3):
            (A) if a husband and wife file a joint federal
        income tax return for a taxable year ending before
        December 31, 2009, they shall file a joint return under
        this Act for such taxable year and their liabilities
        shall be joint and several;
            (B) if a husband and wife file a joint federal
        income tax return for a taxable year ending on or after
        December 31, 2009, they may elect to file separate
        returns under this Act for such taxable year. The
        election under this paragraph must be made on or before
        the due date (including extensions) of the return and,
        once made, shall be irrevocable. If no election is
        timely made under this paragraph for a taxable year:
                (i) the couple must file a joint return under
            this Act for such taxable year,
                (ii) their liabilities shall be joint and
            several, and
                (iii) any overpayment for that taxable year
            may be withheld under Section 909 of this Act or
            under Section 2505-275 of the Civil Administrative
            Code of Illinois and applied against a debt of
            either spouse without regard to the amount of the
            overpayment attributable to the other spouse; and
            (C) if the federal income tax liability of either
        spouse is determined on a separate federal income tax
        return, they shall file separate returns under this
        Act.
        (2) If neither spouse is required to file a federal
    income tax return and either or both are required to file a
    return under this Act, they may elect to file separate or
    joint returns and pursuant to such election their
    liabilities shall be separate or joint and several.
        (3) If either husband or wife is a resident and the
    other is a nonresident, they shall file separate returns in
    this State on such forms as may be required by the
    Department in which event their tax liabilities shall be
    separate; but if they file a joint federal income tax
    return for a taxable year, they may elect to determine
    their joint net income and file a joint return for that
    taxable year under the provisions of paragraph (1) of this
    subsection as if both were residents and in such case,
    their liabilities shall be joint and several.
        (4) Innocent spouses.
            (A) However, for tax liabilities arising and paid
        prior to August 13, 1999, an innocent spouse shall be
        relieved of liability for tax (including interest and
        penalties) for any taxable year for which a joint
        return has been made, upon submission of proof that the
        Internal Revenue Service has made a determination
        under Section 6013(e) of the Internal Revenue Code, for
        the same taxable year, which determination relieved
        the spouse from liability for federal income taxes. If
        there is no federal income tax liability at issue for
        the same taxable year, the Department shall rely on the
        provisions of Section 6013(e) to determine whether the
        person requesting innocent spouse abatement of tax,
        penalty, and interest is entitled to that relief.
            (B) For tax liabilities arising on and after August
        13, 1999 or which arose prior to that date, but remain
        unpaid as of that date, if an individual who filed a
        joint return for any taxable year has made an election
        under this paragraph, the individual's liability for
        any tax shown on the joint return shall not exceed the
        individual's separate return amount and the
        individual's liability for any deficiency assessed for
        that taxable year shall not exceed the portion of the
        deficiency properly allocable to the individual. For
        purposes of this paragraph:
                (i) An election properly made pursuant to
            Section 6015 of the Internal Revenue Code shall
            constitute an election under this paragraph,
            provided that the election shall not be effective
            until the individual has notified the Department
            of the election in the form and manner prescribed
            by the Department.
                (ii) If no election has been made under Section
            6015, the individual may make an election under
            this paragraph in the form and manner prescribed by
            the Department, provided that no election may be
            made if the Department finds that assets were
            transferred between individuals filing a joint
            return as part of a scheme by such individuals to
            avoid payment of Illinois income tax and the
            election shall not eliminate the individual's
            liability for any portion of a deficiency
            attributable to an error on the return of which the
            individual had actual knowledge as of the date of
            filing.
                (iii) In determining the separate return
            amount or portion of any deficiency attributable
            to an individual, the Department shall follow the
            provisions in subsections (c) and (d) of Section
            6015 of the Internal Revenue Code.
                (iv) In determining the validity of an
            individual's election under subparagraph (ii) and
            in determining an electing individual's separate
            return amount or portion of any deficiency under
            subparagraph (iii), any determination made by the
            Secretary of the Treasury, by the United States Tax
            Court on petition for review of a determination by
            the Secretary of the Treasury, or on appeal from
            the United States Tax Court under Section 6015 of
            the Internal Revenue Code regarding criteria for
            eligibility or under subsection (d) of Section
            6015 of the Internal Revenue Code regarding the
            allocation of any item of income, deduction,
            payment, or credit between an individual making
            the federal election and that individual's spouse
            shall be conclusively presumed to be correct. With
            respect to any item that is not the subject of a
            determination by the Secretary of the Treasury or
            the federal courts, in any proceeding involving
            this subsection, the individual making the
            election shall have the burden of proof with
            respect to any item except that the Department
            shall have the burden of proof with respect to
            items in subdivision (ii).
                (v) Any election made by an individual under
            this subsection shall apply to all years for which
            that individual and the spouse named in the
            election have filed a joint return.
                (vi) After receiving a notice that the federal
            election has been made or after receiving an
            election under subdivision (ii), the Department
            shall take no collection action against the
            electing individual for any liability arising from
            a joint return covered by the election until the
            Department has notified the electing individual in
            writing that the election is invalid or of the
            portion of the liability the Department has
            allocated to the electing individual. Within 60
            days (150 days if the individual is outside the
            United States) after the issuance of such
            notification, the individual may file a written
            protest of the denial of the election or of the
            Department's determination of the liability
            allocated to him or her and shall be granted a
            hearing within the Department under the provisions
            of Section 908. If a protest is filed, the
            Department shall take no collection action against
            the electing individual until the decision
            regarding the protest has become final under
            subsection (d) of Section 908 or, if
            administrative review of the Department's decision
            is requested under Section 1201, until the
            decision of the court becomes final.
    (d) Partnerships. Every partnership having any base income
allocable to this State in accordance with section 305(c) shall
retain information concerning all items of income, gain, loss
and deduction; the names and addresses of all of the partners,
or names and addresses of members of a limited liability
company, or other persons who would be entitled to share in the
base income of the partnership if distributed; the amount of
the distributive share of each; and such other pertinent
information as the Department may by forms or regulations
prescribe. The partnership shall make that information
available to the Department when requested by the Department.
    (e) For taxable years ending on or after December 31, 1985,
and before December 31, 1993, taxpayers that are corporations
(other than Subchapter S corporations) having the same taxable
year and that are members of the same unitary business group
may elect to be treated as one taxpayer for purposes of any
original return, amended return which includes the same
taxpayers of the unitary group which joined in the election to
file the original return, extension, claim for refund,
assessment, collection and payment and determination of the
group's tax liability under this Act. This subsection (e) does
not permit the election to be made for some, but not all, of
the purposes enumerated above. For taxable years ending on or
after December 31, 1987, corporate members (other than
Subchapter S corporations) of the same unitary business group
making this subsection (e) election are not required to have
the same taxable year.
    For taxable years ending on or after December 31, 1993,
taxpayers that are corporations (other than Subchapter S
corporations) and that are members of the same unitary business
group shall be treated as one taxpayer for purposes of any
original return, amended return which includes the same
taxpayers of the unitary group which joined in filing the
original return, extension, claim for refund, assessment,
collection and payment and determination of the group's tax
liability under this Act.
    (f) The Department may promulgate regulations to permit
nonresident individual partners of the same partnership,
nonresident Subchapter S corporation shareholders of the same
Subchapter S corporation, and nonresident individuals
transacting an insurance business in Illinois under a Lloyds
plan of operation, and nonresident individual members of the
same limited liability company that is treated as a partnership
under Section 1501 (a)(16) of this Act, to file composite
individual income tax returns reflecting the composite income
of such individuals allocable to Illinois and to make composite
individual income tax payments. The Department may by
regulation also permit such composite returns to include the
income tax owed by Illinois residents attributable to their
income from partnerships, Subchapter S corporations, insurance
businesses organized under a Lloyds plan of operation, or
limited liability companies that are treated as partnership
under Section 1501(a)(16) of this Act, in which case such
Illinois residents will be permitted to claim credits on their
individual returns for their shares of the composite tax
payments. This paragraph of subsection (f) applies to taxable
years ending on or after December 31, 1987.
    For taxable years ending on or after December 31, 1999, the
Department may, by regulation, also permit any persons
transacting an insurance business organized under a Lloyds plan
of operation to file composite returns reflecting the income of
such persons allocable to Illinois and the tax rates applicable
to such persons under Section 201 and to make composite tax
payments and shall, by regulation, also provide that the income
and apportionment factors attributable to the transaction of an
insurance business organized under a Lloyds plan of operation
by any person joining in the filing of a composite return
shall, for purposes of allocating and apportioning income under
Article 3 of this Act and computing net income under Section
202 of this Act, be excluded from any other income and
apportionment factors of that person or of any unitary business
group, as defined in subdivision (a)(27) of Section 1501, to
which that person may belong.
    For taxable years ending on or after December 31, 2008,
every nonresident shall be allowed a credit against his or her
liability under subsections (a) and (b) of Section 201 for any
amount of tax reported on a composite return and paid on his or
her behalf under this subsection (f). Residents (other than
persons transacting an insurance business organized under a
Lloyds plan of operation) may claim a credit for taxes reported
on a composite return and paid on their behalf under this
subsection (f) only as permitted by the Department by rule.
    (f-5) For taxable years ending on or after December 31,
2008, the Department may adopt rules to provide that, when a
partnership or Subchapter S corporation has made an error in
determining the amount of any item of income, deduction,
addition, subtraction, or credit required to be reported on its
return that affects the liability imposed under this Act on a
partner or shareholder, the partnership or Subchapter S
corporation may report the changes in liabilities of its
partners or shareholders and claim a refund of the resulting
overpayments, or pay the resulting underpayments, on behalf of
its partners and shareholders.
    (g) The Department may adopt rules to authorize the
electronic filing of any return required to be filed under this
Section.

    (35 ILCS 5/506)  (from Ch. 120, par. 5-506)
    Sec. 506. Federal Returns.
    (a) In general. Any person required to make a return for a
taxable year under this Act may, at any time that a deficiency
could be assessed or a refund claimed under this Act in respect
of any item reported or properly reportable on such return or
any amendment thereof, be required to furnish to the Department
a true and correct copy of any return which may pertain to such
item and which was filed by such person under the provisions of
the Internal Revenue Code.
    (b) Changes affecting federal income tax. A person shall
notify the Department if:
        (1) the taxable income, any item of income or
    deduction, the income tax liability, or any tax credit
    reported in an original or amended a federal income tax
    return of that person for any year or as determined by the
    Internal Revenue Service or the courts is altered by
    amendment of such return or as a result of any other
    recomputation or redetermination of federal taxable income
    or loss, and such alteration reflects a change or
    settlement with respect to any item or items, affecting the
    computation of such person's net income, net loss, or of
    any credit provided by Article 2 of this Act for any year
    under this Act, or in the number of personal exemptions
    allowable to such person under Section 151 of the Internal
    Revenue Code, or
        (2) the amount of tax required to be withheld by that
    person from compensation paid to employees and required to
    be reported by that person on a federal return is altered
    by amendment of the return or by any other recomputation or
    redetermination that is agreed to or finally determined on
    or after January 1, 2003, and the alteration affects the
    amount of compensation subject to withholding by that
    person under Section 701 of this Act.
Such notification shall be in the form of an amended return or
such other form as the Department may by regulations prescribe,
shall contain the person's name and address and such other
information as the Department may by regulations prescribe,
shall be signed by such person or his duly authorized
representative, and shall be filed not later than 120 days
after such alteration has been agreed to or finally determined
for federal income tax purposes or any federal income tax
deficiency or refund, tentative carryback adjustment,
abatement or credit resulting therefrom has been assessed or
paid, whichever shall first occur.

    (35 ILCS 5/601)  (from Ch. 120, par. 6-601)
    Sec. 601. Payment on Due Date of Return.
    (a) In general. Every taxpayer required to file a return
under this Act shall, without assessment, notice or demand, pay
any tax due thereon to the Department, at the place fixed for
filing, on or before the date fixed for filing such return
(determined without regard to any extension of time for filing
the return) pursuant to regulations prescribed by the
Department. If, however, the due date for payment of a
taxpayer's federal income tax liability for a tax year (as
provided in the Internal Revenue Code or by Treasury
regulation, or as extended by the Internal Revenue Service) is
later than the date fixed for filing the taxpayer's Illinois
income tax return for that tax year, the Department may, by
rule, prescribe a due date for payment that is not later than
the due date for payment of the taxpayer's federal income tax
liability. For purposes of the Illinois Administrative
Procedure Act, the adoption of rules to prescribe a later due
date for payment shall be deemed an emergency and necessary for
the public interest, safety, and welfare.
    (b) Amount payable. In making payment as provided in this
section there shall remain payable only the balance of such tax
remaining due after giving effect to the following:
        (1) Withheld tax. Any amount withheld during any
    calendar year pursuant to Article 7 from compensation paid
    to a taxpayer shall be deemed to have been paid on account
    of any tax imposed by subsections 201(a) and (b) of this
    Act on such taxpayer for his taxable year beginning in such
    calendar year. If more than one taxable year begins in a
    calendar year, such amount shall be deemed to have been
    paid on account of such tax for the last taxable year so
    beginning.
        (2) Estimated and tentative tax payments. Any amount of
    estimated tax paid by a taxpayer pursuant to Article 8 for
    a taxable year shall be deemed to have been paid on account
    of the tax imposed by this Act for such taxable year.
        (3) Foreign tax. The aggregate amount of tax which is
    imposed upon or measured by income and which is paid by a
    resident for a taxable year to another state or states on
    income which is also subject to the tax imposed by
    subsections 201(a) and (b) of this Act shall be credited
    against the tax imposed by subsections 201(a) and (b)
    otherwise due under this Act for such taxable year. For
    taxable years ending prior to December 31, 2009, the
    aggregate credit provided under this paragraph shall not
    exceed that amount which bears the same ratio to the tax
    imposed by subsections 201(a) and (b) otherwise due under
    this Act as the amount of the taxpayer's base income
    subject to tax both by such other state or states and by
    this State bears to his total base income subject to tax by
    this State for the taxable year. For taxable years ending
    on or after December 31, 2009, the credit provided under
    this paragraph for tax paid to other states shall not
    exceed that amount which bears the same ratio to the tax
    imposed by subsections 201(a) and (b) otherwise due under
    this Act as the amount of the taxpayer's base income that
    would be allocated or apportioned to other states if all
    other states had adopted the provisions in Article 3 of
    this Act bears to the taxpayer's total base income subject
    to tax by this State for the taxable year. The credit
    provided by this paragraph shall not be allowed if any
    creditable tax was deducted in determining base income for
    the taxable year. Any person claiming such credit shall
    attach a statement in support thereof and shall notify the
    Director of any refund or reductions in the amount of tax
    claimed as a credit hereunder all in such manner and at
    such time as the Department shall by regulations prescribe.
        (4) Accumulation and capital gain distributions. If
    the net income of a taxpayer includes amounts included in
    his base income by reason of Section 667 668 or 669 of the
    Internal Revenue Code (relating to accumulation and
    capital gain distributions by a trust, respectively), the
    tax imposed on such taxpayer by this Act shall be credited
    with his pro rata portion of the taxes imposed by this Act
    on such trust for preceding taxable years which would not
    have been payable for such preceding years if the trust had
    in fact made distributions to its beneficiaries at the
    times and in the amounts specified in Sections 666 and 669
    of the Internal Revenue Code. The credit provided by this
    paragraph shall not reduce the tax otherwise due from the
    taxpayer to an amount less than that which would be due if
    the amounts included by reason of Section 667 Sections 668
    and 669 of the Internal Revenue Code were excluded from his
    or her base income.
    (c) Cross reference. For application against tax due of
overpayments of tax for a prior year, see Section 909.

    (35 ILCS 5/701)  (from Ch. 120, par. 7-701)
    Sec. 701. Requirement and Amount of Withholding.
    (a) In General. Every employer maintaining an office or
transacting business within this State and required under the
provisions of the Internal Revenue Code to withhold a tax on:
        (1) compensation paid in this State (as determined
    under Section 304(a)(2)(B) to an individual; or
        (2) payments described in subsection (b) shall deduct
    and withhold from such compensation for each payroll period
    (as defined in Section 3401 of the Internal Revenue Code)
    an amount equal to the amount by which such individual's
    compensation exceeds the proportionate part of this
    withholding exemption (computed as provided in Section
    702) attributable to the payroll period for which such
    compensation is payable multiplied by a percentage equal to
    the percentage tax rate for individuals provided in
    subsection (b) of Section 201.
    (b) Payment to Residents. Any payment (including
compensation) to a resident by a payor maintaining an office or
transacting business within this State (including any agency,
officer, or employee of this State or of any political
subdivision of this State) and on which withholding of tax is
required under the provisions of the Internal Revenue Code
shall be deemed to be compensation paid in this State by an
employer to an employee for the purposes of Article 7 and
Section 601(b)(1) to the extent such payment is included in the
recipient's base income and not subjected to withholding by
another state. Notwithstanding any other provision to the
contrary, no amount shall be withheld from unemployment
insurance benefit payments made to an individual pursuant to
the Unemployment Insurance Act unless the individual has
voluntarily elected the withholding pursuant to rules
promulgated by the Director of Employment Security.
    (c) Special Definitions. Withholding shall be considered
required under the provisions of the Internal Revenue Code to
the extent the Internal Revenue Code either requires
withholding or allows for voluntary withholding the payor and
recipient have entered into such a voluntary withholding
agreement. For the purposes of Article 7 and Section 1002(c)
the term "employer" includes any payor who is required to
withhold tax pursuant to this Section.
    (d) Reciprocal Exemption. The Director may enter into an
agreement with the taxing authorities of any state which
imposes a tax on or measured by income to provide that
compensation paid in such state to residents of this State
shall be exempt from withholding of such tax; in such case, any
compensation paid in this State to residents of such state
shall be exempt from withholding. All reciprocal agreements
shall be subject to the requirements of Section 2505-575 of the
Department of Revenue Law (20 ILCS 2505/2505-575).
    (e) Notwithstanding subsection (a)(2) of this Section, no
withholding is required on payments for which withholding is
required under Section 3405 or 3406 of the Internal Revenue
Code of 1954.

    (35 ILCS 5/702)  (from Ch. 120, par. 7-702)
    Sec. 702. Amount Exempt from Withholding. For purposes of
this Section an employee shall be entitled to a withholding
exemption in an amount equal to the basic amount in Section
204(b) for each personal or dependent exemption which he is
entitled to claim on his federal return pursuant to Section 151
of the Internal Revenue Code of 1986; plus an allowance equal
to $1,000 for each $1,000 he is entitled to deduct from gross
income in arriving at adjusted gross income pursuant to Section
62 of the Internal Revenue Code of 1986; plus an additional
allowance equal to $1,000 for each $1,000 eligible for
subtraction on his Illinois income tax return as Illinois real
estate taxes paid during the taxable year; or in any lesser
amount claimed by him. Every employee shall furnish to his
employer such information as is required for the employer to
make an accurate withholding under this Act. The employer may
rely on this information for withholding purposes. If any
employee fails or refuses to furnish such information, the
employer shall withhold the full rate of tax from the
employee's total compensation.

to deduct and withhold tax under this Act from compensation of
an employee, or who would have been required so to deduct and
withhold tax if the employee's withholding exemption were not
in excess of the basic amount in Section 204(b), shall furnish
in duplicate to each such employee in respect of the
compensation paid by such employer to such employee during the
calendar year on or before January 31 of the succeeding year,
or, if his employment is terminated before the close of such
calendar year, on the date on which the last payment of
compensation is made, a written statement in such form as the
Department may by regulation prescribe showing the amount of
compensation paid by the employer to the employee, the amount
deducted and withheld as tax, the tax-exempt amount contributed
to a medical savings account, and such other information as the
Department shall prescribe. A copy of such statement shall be
filed by the employee with his return for his taxable year to
which it relates (as determined under Section 601(b)(1)).

comply with the requirements of this Section with respect to
such employees by filing an annual return and paying the taxes
required to be deducted and withheld on or before the 15th day
of the fourth month following the close of the employer's

    (g) For amounts deducted or withheld after December 31,
2009, a taxpayer who makes an election under subsection (f) of
Section 5-15 of the Economic Development for a Growing Economy
Tax Credit Act for a taxable year shall be allowed a credit
against payments due under this Section for amounts withheld
during the first calendar year beginning after the end of that
taxable year equal to the amount of the credit for the
incremental income tax attributable to full-time employees of
the taxpayer awarded to the taxpayer by the Department of
Commerce and Economic Opportunity under the Economic
Development for a Growing Economy Tax Credit Act for the
taxable year and credits not previously claimed and allowed to
be carried forward under Section 211(4) of this Act as provided
in subsection (f) of Section 5-15 of the Economic Development
for a Growing Economy Tax Credit Act. The credit or credits may
not reduce the taxpayer's obligation for any payment due under
this Section to less than zero. If the amount of the credit or
credits exceeds the total payments due under this Section with
respect to amounts withheld during the calendar year, the
excess may be carried forward and applied against the
taxpayer's liability under this Section in the succeeding
calendar years as allowed to be carried forward under paragraph
(4) of Section 211 of this Act. The credit or credits shall be
applied to the earliest year for which there is a tax
liability. If there are credits from more than one taxable year
that are available to offset a liability, the earlier credit
shall be applied first. Each employer who deducts and withholds
or is required to deduct and withhold tax under this Act and
who retains income tax withholdings under subsection (f) of
Section 5-15 of the Economic Development for a Growing Economy
Tax Credit Act must make a return with respect to such taxes
and retained amounts in the form and manner that the
Department, by rule, requires and pay to the Department or to a
depositary designated by the Department those withheld taxes
not retained by the taxpayer. For purposes of this subsection
(g), the term taxpayer shall include taxpayer and members of
the taxpayer's unitary business group as defined under
paragraph (27) of subsection (a) of Section 1501 of this Act.
This Section is exempt from the provisions of Section 250 of
this Act.
    (h) An employer may claim a credit against payments due
under this Section for amounts withheld during the first
calendar year ending after the date on which a tax credit
certificate was issued under Section 35 of the Small Business
Job Creation Tax Credit Act. The credit shall be equal to the
amount shown on the certificate, but may not reduce the
taxpayer's obligation for any payment due under this Section to
less than zero. If the amount of the credit exceeds the total
payments due under this Section with respect to amounts
withheld during the calendar year, the excess may be carried
forward and applied against the taxpayer's liability under this
Section in the 5 succeeding calendar years. The credit shall be
applied to the earliest year for which there is a tax
liability. If there are credits from more than one calendar
year that are available to offset a liability, the earlier
credit shall be applied first. This Section is exempt from the
provisions of Section 250 of this Act.

December 31, 2008, every partnership (other than a publicly
traded partnership under Section 7704 of the Internal Revenue
Code or investment partnership), Subchapter S corporation, and
trust must withhold from each nonresident partner,

Section 201 of this Act.
    (b) Credit for taxes withheld. Any amount withheld under
subsection (a) of this Section and paid to the Department shall
be treated as a payment of the estimated tax liability or of
the liability for withholding under this Section of the
partner, shareholder, or beneficiary to whom the income is
distributable for the taxable year in which that person
incurred a liability under this Act with respect to that
income. The Department shall adopt rules pursuant to which a
partner, shareholder, or beneficiary may claim a credit against
its obligation for withholding under this Section for amounts
withheld under this Section with respect to income
distributable to it by a partnership, Subchapter S corporation,
or trust and allowing its partners, shareholders, or
beneficiaries to claim a credit under this subsection (b) for
those withheld amounts.
    (c) Exemption from withholding.
        (1) A partnership, Subchapter S corporation, or trust
    shall not be required to withhold tax under subsection (a)
    of this Section with respect to any nonresident partner,
    shareholder, or beneficiary (other than an individual)
    from whom the partnership, S corporation, or trust has
    received a certificate, completed in the form and manner
    prescribed by the Department, stating that such
    nonresident partner, shareholder, or beneficiary shall:
            (A) file all returns that the partner,
        shareholder, or beneficiary is required to file under
        Section 502 of this Act and make timely payment of all
        taxes imposed under Section 201 of this Act or under
        this Section on the partner, shareholder, or
        beneficiary with respect to income of the partnership,
        S corporation, or trust; and
            (B) be subject to personal jurisdiction in this
        State for purposes of the collection of income taxes,
        together with related interest and penalties, imposed
        on the partner, shareholder, or beneficiary with
        respect to the income of the partnership, S
        corporation, or trust.
        (2) The Department may revoke the exemption provided by
    this subsection (c) at any time that it determines that the
    nonresident partner, shareholder, or beneficiary is not
    abiding by the terms of the certificate. The Department
    shall notify the partnership, S corporation, or trust that
    it has revoked a certificate by notice left at the usual
    place of business of the partnership, S corporation, or
    trust or by mail to the last known address of the
    partnership, S corporation, or trust.
        (3) A partnership, S corporation, or trust that
    receives a certificate under this subsection (c) properly
    completed by a nonresident partner, shareholder, or
    beneficiary shall not be required to withhold any amount
    from that partner, shareholder, or beneficiary, the
    payment of which would be due under Section 711(a-5) of

    corporation, or trust under this subsection (c) must be
    retained by the partnership, S corporation, or trust and a
    record of such certificates must be provided to the

    for review by the Department, upon request by the
    Department. The Department may, by rule, require the record
    of certificates to be maintained and provided to the
    Department electronically.

    Sec. 804. Failure to Pay Estimated Tax.
    (a) In general. In case of any underpayment of estimated
tax by a taxpayer, except as provided in subsection (d) or (e),
the taxpayer shall be liable to a penalty in an amount
determined at the rate prescribed by Section 3-3 of the Uniform
Penalty and Interest Act upon the amount of the underpayment
(determined under subsection (b)) for each required
installment.
    (b) Amount of underpayment. For purposes of subsection (a),
the amount of the underpayment shall be the excess of:
        (1) the amount of the installment which would be
    required to be paid under subsection (c), over
        (2) the amount, if any, of the installment paid on or
    before the last date prescribed for payment.
    (c) Amount of Required Installments.
        (1) Amount.
            (A) In General. Except as provided in paragraph
        (2), the amount of any required installment shall be
        25% of the required annual payment.
            (B) Required Annual Payment. For purposes of
        subparagraph (A), the term "required annual payment"
        means the lesser of
                (i) 90% of the tax shown on the return for the
            taxable year, or if no return is filed, 90% of the
            tax for such year,
                (ii) for installments due prior to February 1,
            2011, and after January 31, 2012, 100% of the tax
            shown on the return of the taxpayer for the

            preceding taxable year and such preceding year was
            a taxable year of 12 months; or
                (iii) for installments due after January 31,
            2011, and prior to February 1, 2012, 150% of the
            tax shown on the return of the taxpayer for the
            preceding taxable year if a return showing a
            liability for tax was filed by the taxpayer for the
            preceding taxable year and such preceding year was
            a taxable year of 12 months.
        (2) Lower Required Installment where Annualized Income
    Installment is Less Than Amount Determined Under Paragraph
    (1).
            (A) In General. In the case of any required
        installment if a taxpayer establishes that the
        annualized income installment is less than the amount
        determined under paragraph (1),
                (i) the amount of such required installment
            shall be the annualized income installment, and
                (ii) any reduction in a required installment
            resulting from the application of this
            subparagraph shall be recaptured by increasing the
            amount of the next required installment determined
            under paragraph (1) by the amount of such
            reduction, and by increasing subsequent required
            installments to the extent that the reduction has
            not previously been recaptured under this clause.
            (B) Determination of Annualized Income
        Installment. In the case of any required installment,
        the annualized income installment is the excess, if
        any, of
                (i) an amount equal to the applicable
            percentage of the tax for the taxable year computed
            by placing on an annualized basis the net income
            for months in the taxable year ending before the
            due date for the installment, over
                (ii) the aggregate amount of any prior
            required installments for the taxable year.
            (C) Applicable Percentage.
        In the case of the followingThe applicable
        required installments:percentage is:

        3rd ...............................67.5%
        4th ...............................90%
            (D) Annualized Net Income; Individuals. For
        individuals, net income shall be placed on an
        annualized basis by:
                (i) multiplying by 12, or in the case of a
            taxable year of less than 12 months, by the number
            of months in the taxable year, the net income
            computed without regard to the standard exemption
            for the months in the taxable year ending before
            the month in which the installment is required to
            be paid;
                (ii) dividing the resulting amount by the
            number of months in the taxable year ending before
            the month in which such installment date falls; and
                (iii) deducting from such amount the standard
            exemption allowable for the taxable year, such
            standard exemption being determined as of the last
            date prescribed for payment of the installment.
            (E) Annualized Net Income; Corporations. For
        corporations, net income shall be placed on an
        annualized basis by multiplying by 12 the taxable
        income
                (i) for the first 3 months of the taxable year,
            in the case of the installment required to be paid
            in the 4th month,
                (ii) for the first 3 months or for the first 5
            months of the taxable year, in the case of the
            installment required to be paid in the 6th month,

preceding subsections, the penalty imposed by subsection (a)
shall not be imposed if the taxpayer was not required to file
an Illinois income tax return for the preceding taxable year,
or, for individuals, if the taxpayer had no tax liability for
the preceding taxable year and such year was a taxable year of
12 months. The penalty imposed by subsection (a) shall also not
be imposed on any underpayments of estimated tax due before the
effective date of this amendatory Act of 1998 which
underpayments are solely attributable to the change in
apportionment from subsection (a) to subsection (h) of Section
304. The provisions of this amendatory Act of 1998 apply to tax
years ending on or after December 31, 1998.
    (e) The penalty imposed for underpayment of estimated tax
by subsection (a) of this Section shall not be imposed to the
extent that the Director or his or her designate determines,
pursuant to Section 3-8 of the Uniform Penalty and Interest Act

(c), the term "tax" means the excess of the tax imposed under
Article 2 of this Act, over the amounts credited against such
tax under Sections 601(b) (3) and (4).
    (g) Application of Section in case of tax withheld under
Article 7. For purposes of applying this Section:
        (1) in the case of an individual, tax withheld from
    compensation for the taxable year shall be deemed a payment
    of estimated tax, and an equal part of such amount shall be
    deemed paid on each installment date for such taxable year,
    unless the taxpayer establishes the dates on which all
    amounts were actually withheld, in which case the amounts
    so withheld shall be deemed payments of estimated tax on
    the dates on which such amounts were actually withheld;
        (2) amounts timely paid by a partnership, Subchapter S
    corporation, or trust on behalf of a partner, shareholder,
    or beneficiary pursuant to subsection (f) of Section 502 or
    Section 709.5 and claimed as a payment of estimated tax
    shall be deemed a payment of estimated tax made on the last
    day of the taxable year of the partnership, Subchapter S
    corporation, or trust for which the income from the
    withholding is made was computed; and
        (3) all other amounts pursuant to Article 7 shall be
    deemed a payment of estimated tax on the date the payment
    is made to the taxpayer of the amount from which the tax is
    withheld.
    (g-5) Amounts withheld under the State Salary and Annuity
Withholding Act. An individual who has amounts withheld under
paragraph (10) of Section 4 of the State Salary and Annuity
Withholding Act may elect to have those amounts treated as
payments of estimated tax made on the dates on which those
amounts are actually withheld.

taxable years of less than 12 months shall be in accordance
with regulations prescribed by the Department.

    (35 ILCS 5/909)  (from Ch. 120, par. 9-909)
    Sec. 909. Credits and Refunds.
    (a) In general. In the case of any overpayment, the
Department, within the applicable period of limitations for a
claim for refund, may credit the amount of such overpayment,
including any interest allowed thereon, against any liability
in respect of the tax imposed by this Act, regardless of
whether other collection remedies are closed to the Department
on the part of the person who made the overpayment and shall
refund any balance to such person.
    (b) Credits against estimated tax. The Department may
prescribe regulations providing for the crediting against the
estimated tax for any taxable year of the amount determined by
the taxpayer or the Department to be an overpayment of the tax
imposed by this Act for a preceding taxable year.
    (c) Interest on overpayment. Interest shall be allowed and
paid at the rate and in the manner prescribed in Section 3-2 of
the Uniform Penalty and Interest Act upon any overpayment in
respect of the tax imposed by this Act. For purposes of this
subsection, no amount of tax, for any taxable year, shall be
treated as having been paid before the date on which the tax
return for such year was due under Section 505, without regard
to any extension of the time for filing such return.
    (d) Refund claim. Every claim for refund shall be filed
with the Department in writing in such form as the Department
may by regulations prescribe, and shall state the specific
grounds upon which it is founded.
    (e) Notice of denial. As soon as practicable after a claim
for refund is filed, the Department shall examine it and either
issue a notice of refund, abatement or credit to the claimant
or issue a notice of denial. If the Department has failed to
approve or deny the claim before the expiration of 6 months
from the date the claim was filed, the claimant may
nevertheless thereafter file with the Department a written
protest in such form as the Department may by regulation
prescribe. If a protest is filed, the Department shall consider
the claim and, if the taxpayer has so requested, shall grant
the taxpayer or the taxpayer's authorized representative a
hearing within 6 months after the date such request is filed.
    (f) Effect of denial. A denial of a claim for refund
becomes final 60 days after the date of issuance of the notice
of such denial except for such amounts denied as to which the
claimant has filed a protest with the Department, as provided
by Section 910.
    (g) An overpayment of tax shown on the face of an unsigned
return shall be considered forfeited to the State if after
notice and demand for signature by the Department the taxpayer
fails to provide a signature and 3 years have passed from the
date the return was filed. An overpayment of tax refunded to a
taxpayer whose return was filed electronically shall be
considered an erroneous refund under Section 912 of this Act
if, after proper notice and demand by the Department, the
taxpayer fails to provide a required signature document. A
notice and demand for signature in the case of a return
reflecting an overpayment may be made by first class mail. This
subsection (g) shall apply to all returns filed pursuant to
this Act since 1969.
    (h) This amendatory Act of 1983 applies to returns and
claims for refunds filed with the Department on and after July
1, 1983.

    Sec. 911. Limitations on Claims for Refund.
    (a) In general. Except as otherwise provided in this Act:
        (1) A claim for refund shall be filed not later than 3
    years after the date the return was filed (in the case of
    returns required under Article 7 of this Act respecting any
    amounts withheld as tax, not later than 3 years after the
    15th day of the 4th month following the close of the
    calendar year in which such withholding was made), or one
    year after the date the tax was paid, whichever is the
    later; and
        (2) No credit or refund shall be allowed or made with
    respect to the year for which the claim was filed unless
    such claim is filed within such period.
    (b) Federal changes.
        (1) In general. In any case where notification of an
    alteration is required by Section 506(b), a claim for
    refund may be filed within 2 years after the date on which
    such notification was due (regardless of whether such
    notice was given), but the amount recoverable pursuant to a
    claim filed under this Section shall be limited to the
    amount of any overpayment resulting under this Act from
    recomputation of the taxpayer's net income, net loss, or
    Article 2 credits for the taxable year after giving effect
    to the item or items reflected in the alteration required
    to be reported.
        (2) Tentative carryback adjustments paid before
    January 1, 1974. If, as the result of the payment before
    January 1, 1974 of a federal tentative carryback
    adjustment, a notification of an alteration is required
    under Section 506(b), a claim for refund may be filed at
    any time before January 1, 1976, but the amount recoverable
    pursuant to a claim filed under this Section shall be
    limited to the amount of any overpayment resulting under
    this Act from recomputation of the taxpayer's base income
    for the taxable year after giving effect to the federal
    alteration resulting from the tentative carryback
    adjustment irrespective of any limitation imposed in
    paragraph (l) of this subsection.
    (c) Extension by agreement. Where, before the expiration of
the time prescribed in this section for the filing of a claim
for refund, both the Department and the claimant shall have
consented in writing to its filing after such time, such claim
may be filed at any time prior to the expiration of the period
agreed upon. The period so agreed upon may be extended by
subsequent agreements in writing made before the expiration of
the period previously agreed upon. In the case of a taxpayer
who is a partnership, Subchapter S corporation, or trust and
who enters into an agreement with the Department pursuant to
this subsection on or after January 1, 2003, a claim for refund
may be filed by issued to the partners, shareholders, or
beneficiaries of the taxpayer at any time prior to the
expiration of the period agreed upon. Any refund allowed
pursuant to the claim, however, shall be limited to the amount
of any overpayment of tax due under this Act that results from
recomputation of items of income, deduction, credits, or other
amounts of the taxpayer that are taken into account by the
partner, shareholder, or beneficiary in computing its
liability under this Act.
    (d) Limit on amount of credit or refund.
        (1) Limit where claim filed within 3-year period. If
    the claim was filed by the claimant during the 3-year
    period prescribed in subsection (a), the amount of the
    credit or refund shall not exceed the portion of the tax
    paid within the period, immediately preceding the filing of
    the claim, equal to 3 years plus the period of any
    extension of time for filing the return.
        (2) Limit where claim not filed within 3-year period.
    If the claim was not filed within such 3-year period, the
    amount of the credit or refund shall not exceed the portion
    of the tax paid during the one year immediately preceding
    the filing of the claim.
    (e) Time return deemed filed. For purposes of this section
a tax return filed before the last day prescribed by law for
the filing of such return (including any extensions thereof)
shall be deemed to have been filed on such last day.
    (f) No claim for refund or credit based on the taxpayer's
taking a credit for estimated tax payments as provided by
Section 601(b)(2) or for any amount paid by a taxpayer pursuant
to Section 602(a) or for any amount of credit for tax withheld
pursuant to Article 7 may be filed unless a return was filed
for the tax year not more than 3 years after the due date, as
provided by Section 505, of the return which was required to be
filed relative to the taxable year for which the payments were
made or for which the tax was withheld. The changes in this
subsection (f) made by this amendatory Act of 1987 shall apply
to all taxable years ending on or after December 31, 1969.
    (g) Special Period of Limitation with Respect to Net Loss
Carrybacks. If the claim for refund relates to an overpayment
attributable to a net loss carryback as provided by Section
207, in lieu of the 3 year period of limitation prescribed in
subsection (a), the period shall be that period which ends 3
years after the time prescribed by law for filing the return
(including extensions thereof) for the taxable year of the net
loss which results in such carryback (or, on and after August
13, 1999, with respect to a change in the carryover of an
Article 2 credit to a taxable year resulting from the carryback
of a Section 207 loss incurred in a taxable year beginning on
or after January 1, 2000, the period shall be that period that
ends 3 years after the time prescribed by law for filing the
return (including extensions of that time) for that subsequent
taxable year), or the period prescribed in subsection (c) in
respect of such taxable year, whichever expires later. In the
case of such a claim, the amount of the refund may exceed the
portion of the tax paid within the period provided in
subsection (d) to the extent of the amount of the overpayment
attributable to such carryback. On and after August 13, 1999,
if the claim for refund relates to an overpayment attributable
to the carryover of an Article 2 credit, or of a Section 207
loss, earned, incurred (in a taxable year beginning on or after
January 1, 2000), or used in a year for which a notification of
a change affecting federal taxable income must be filed under
subsection (b) of Section 506, the claim may be filed within
the period prescribed in paragraph (1) of subsection (b) in
respect of the year for which the notification is required. In
the case of such a claim, the amount of the refund may exceed
the portion of the tax paid within the period provided in
subsection (d) to the extent of the amount of the overpayment
attributable to the recomputation of the taxpayer's Article 2
credits, or Section 207 loss, earned, incurred, or used in the
taxable year for which the notification is given.
    (h) Claim for refund based on net loss. On and after August
23, 2002, no claim for refund shall be allowed to the extent
the refund is the result of an amount of net loss incurred in
any taxable year ending prior to December 31, 2002 under
Section 207 of this Act that was not reported to the Department
within 3 years of the due date (including extensions) of the
return for the loss year on either the original return filed by
the taxpayer or on amended return or to the extent that the
refund is the result of an amount of net loss incurred in any
taxable year under Section 207 for which no return was filed
within 3 years of the due date (including extensions) of the
return for the loss year.

such taxes and shall pay the same together with the interest
and the penalty provided by Sections 3-2 and 3-3, respectively,
of the Uniform Penalty and Interest Act and such interest and
penalty shall not be charged to or collected from the employee
by the employer.
    (d) Willful failure to collect and pay over tax. Any person
required to collect, truthfully account for, and pay over the
tax imposed by this Act who willfully fails to collect such tax

    Act or the Uniform Penalty and Interest Act, the penalties
    provided by this Act or by the Uniform Penalty and Interest
    Act shall be paid upon notice and demand and shall be

    (b). The penalty imposed under Section 1005(a) 1005(b)

    on notice and demand in the same manner as the tax.
    (f) Determination of deficiency. For purposes of
subsections (a) and (b), the amount shown as the tax by the

filing of such return, including any extensions of the time for
such filing.

    Sec. 1101. Lien for Tax.
    (a) If any person liable to pay any tax neglects or refuses
to pay the same after demand, the amount (including any
interest, additional amount, addition to tax, or assessable
penalty, together with any costs that may accrue in addition
thereto) shall be a lien in favor of the State of Illinois upon
all property and rights to property, whether real or personal,
belonging to such person.
    (b) Unless another date is specifically fixed by law, the
lien imposed by subsection (a) of this Section shall arise at

unenforceable by reason of lapse of time.
    (c) Deficiency procedure. If the lien arises from an
assessment pursuant to a notice of deficiency, such lien shall
not attach and the notice referred to in this section shall not

unless a notice of lien is filed within 3 years from the date
such return was filed with the Department. For the purposes of
this subsection (d) (c), a tax return filed before the last day
prescribed by law, including any extension thereof, shall be
deemed to have been filed on such last day. The time limitation

            receivables, the business of making loans for the

            finance company may purchase a customer receivable
            from, or make a loan secured by a customer
            receivable to, the seller in the original
            transaction or to a person who purchased the
            customer receivable directly or indirectly from

                of the Internal Revenue Code;
                    (b) more than 50% of the gross income of
                the corporation for the taxable year must be
                interest income derived from qualifying loans.
                A "qualifying loan" is a loan made to a member
                of the corporation's affiliated group that
                originates customer receivables (within the
                meaning of item (i)) or to whom customer
                receivables originated by a member of the
                affiliated group have been transferred, to the
                extent the average outstanding balance of
                loans from that corporation to members of its
                affiliated group during the taxable year do not
                exceed the limitation amount for that
                corporation. The "limitation amount" for a
                corporation is the average outstanding
                balances during the taxable year of customer
                receivables (within the meaning of item (i))
                originated by all members of the affiliated
                group. If the average outstanding balances of
                the loans made by a corporation to members of
                its affiliated group exceed the limitation
                amount, the interest income of that
                corporation from qualifying loans shall be
                equal to its interest income from loans to
                members of its affiliated groups times a
                fraction equal to the limitation amount
                divided by the average outstanding balances of
                the loans made by that corporation to members
                of its affiliated group;
                    (c) the total of all shareholder's equity
                (including, without limitation, paid-in
                capital on common and preferred stock and
                retained earnings) of the corporation plus the
                total of all of its loans, advances, and other
                obligations payable or owed to members of its
                affiliated group may not exceed 20% of the
                total assets of the corporation at any time
                during the tax year; and
                    (d) more than 50% of all interest-bearing
                obligations of the affiliated group payable to
                persons outside the group determined in
                accordance with generally accepted accounting
                principles must be obligations of the
                corporation.
            This amendatory Act of the 91st General Assembly is
        declaratory of existing law.
            (D) Subparagraphs (B) and (C) of this paragraph are
        declaratory of existing law and apply retroactively,
        for all tax years beginning on or before December 31,
        1996, to all original returns, to all amended returns
        filed no later than 30 days after the effective date of
        this amendatory Act of 1996, and to all notices issued
        on or before the effective date of this amendatory Act
        of 1996 under subsection (a) of Section 903, subsection
        (a) of Section 904, subsection (e) of Section 909, or
        Section 912. A taxpayer that is a "financial
        organization" that engages in any transaction with an
        affiliate shall be a "financial organization" for all
        purposes of this Act.
            (E) For all tax years beginning on or before
        December 31, 1996, a taxpayer that falls within the
        definition of a "financial organization" under
        subparagraphs (B) or (C) of this paragraph, but who
        does not fall within the definition of a "financial
        organization" under the Proposed Regulations issued by
        the Department of Revenue on July 19, 1996, may
        irrevocably elect to apply the Proposed Regulations
        for all of those years as though the Proposed
        Regulations had been lawfully promulgated, adopted,
        and in effect for all of those years. For purposes of
        applying subparagraphs (B) or (C) of this paragraph to
        all of those years, the election allowed by this
        subparagraph applies only to the taxpayer making the
        election and to those members of the taxpayer's unitary
        business group who are ordinarily required to
        apportion business income under the same subsection of
        Section 304 of this Act as the taxpayer making the
        election. No election allowed by this subparagraph
        shall be made under a claim filed under subsection (d)
        of Section 909 more than 30 days after the effective
        date of this amendatory Act of 1996.
            (F) Finance Leases. For purposes of this
        subsection, a finance lease shall be treated as a loan
        or other extension of credit, rather than as a lease,
        regardless of how the transaction is characterized for
        any other purpose, including the purposes of any
        regulatory agency to which the lessor is subject. A
        finance lease is any transaction in the form of a lease
        in which the lessee is treated as the owner of the
        leased asset entitled to any deduction for
        depreciation allowed under Section 167 of the Internal
        Revenue Code.
        (9) Fiscal year. The term "fiscal year" means an
    accounting period of 12 months ending on the last day of
    any month other than December.
        (9.5) Fixed place of business. The term "fixed place of
    business" has the same meaning as that term is given in
    Section 864 of the Internal Revenue Code and the related
    Treasury regulations.
        (10) Includes and including. The terms "includes" and
    "including" when used in a definition contained in this Act
    shall not be deemed to exclude other things otherwise
    within the meaning of the term defined.
        (11) Internal Revenue Code. The term "Internal Revenue
    Code" means the United States Internal Revenue Code of 1954
    or any successor law or laws relating to federal income
    taxes in effect for the taxable year.
        (11.5) Investment partnership.
            (A) The term "investment partnership" means any
        entity that is treated as a partnership for federal
        income tax purposes that meets the following
        requirements:
                (i) no less than 90% of the partnership's cost
            of its total assets consists of qualifying
            investment securities, deposits at banks or other
            financial institutions, and office space and
            equipment reasonably necessary to carry on its
            activities as an investment partnership;
                (ii) no less than 90% of its gross income
            consists of interest, dividends, and gains from
            the sale or exchange of qualifying investment
            securities; and

            qualifying investment securities.
            (B) For purposes of this paragraph (11.5), the term
        "qualifying investment securities" includes all of the
        following:

            preferred stock;

            forward and futures contracts on foreign
            currencies;
                (vii) stock and bond index securities and
            futures contracts and other similar financial

    includes the following types of errors, omissions, or
    defects in a return filed by a taxpayer which prevents
    acceptance of the return as filed for processing:
            (A) arithmetic errors or incorrect computations on
        the return or supporting schedules;

            (C) omission of required supporting forms or
        schedules or the omission of the information in whole

            (D) an attempt to claim, exclude, deduct, or
        improperly report, in a manner directly contrary to the
        provisions of the Act and regulations thereunder any

        (24) Taxpayer. The term "taxpayer" means any person
    subject to the tax imposed by this Act.
        (25) International banking facility. The term

            directly or indirectly affects the tax liability
            of the taxpayer whose claims he or she is
            preparing.
        (27) Unitary business group.
            (A) The term "unitary business group" means a group
        of persons related through common ownership whose
        business activities are integrated with, dependent
        upon and contribute to each other. The group will not
        include those members whose business activity outside
        the United States is 80% or more of any such member's
        total business activity; for purposes of this
        paragraph and clause (a)(3)(B)(ii) of Section 304,
        business activity within the United States shall be
        measured by means of the factors ordinarily applicable
        under subsections (a), (b), (c), (d), or (h) of Section
        304 except that, in the case of members ordinarily
        required to apportion business income by means of the 3
        factor formula of property, payroll and sales
        specified in subsection (a) of Section 304, including
        the formula as weighted in subsection (h) of Section
        304, such members shall not use the sales factor in the
        computation and the results of the property and payroll
        factor computations of subsection (a) of Section 304
        shall be divided by 2 (by one if either the property or
        payroll factor has a denominator of zero). The
        computation required by the preceding sentence shall,
        in each case, involve the division of the member's
        property, payroll, or revenue miles in the United
        States, insurance premiums on property or risk in the
        United States, or financial organization business
        income from sources within the United States, as the
        case may be, by the respective worldwide figures for
        such items. Common ownership in the case of
        corporations is the direct or indirect control or
        ownership of more than 50% of the outstanding voting
        stock of the persons carrying on unitary business
        activity. Unitary business activity can ordinarily be
        illustrated where the activities of the members are:
        (1) in the same general line (such as manufacturing,
        wholesaling, retailing of tangible personal property,
        insurance, transportation or finance); or (2) are
        steps in a vertically structured enterprise or process
        (such as the steps involved in the production of
        natural resources, which might include exploration,
        mining, refining, and marketing); and, in either
        instance, the members are functionally integrated
        through the exercise of strong centralized management
        (where, for example, authority over such matters as
        purchasing, financing, tax compliance, product line,
        personnel, marketing and capital investment is not
        left to each member).
            (B) In no event, shall however, will any unitary
        business group include members which are ordinarily
        required to apportion business income under different
        subsections of Section 304 except that for tax years
        ending on or after December 31, 1987 this prohibition
        shall not apply to a holding company that would
        otherwise be a member of a unitary business group with
        taxpayers that apportion business income under any of
        subsections (b), (c), or (d) of Section 304 unitary
        business group composed of one or more taxpayers all of
        which apportion business income pursuant to subsection
        (b) of Section 304, or all of which apportion business
        income pursuant to subsection (d) of Section 304, and a
        holding company of such single-factor taxpayers (see
        definition of "financial organization" for rule
        regarding holding companies of financial
        organizations). If a unitary business group would, but
        for the preceding sentence, include members that are
        ordinarily required to apportion business income under
        different subsections of Section 304, then for each
        subsection of Section 304 for which there are two or
        more members, there shall be a separate unitary
        business group composed of such members. For purposes
        of the preceding two sentences, a member is "ordinarily
        required to apportion business income" under a
        particular subsection of Section 304 if it would be
        required to use the apportionment method prescribed by
        such subsection except for the fact that it derives
        business income solely from Illinois. As used in this
        paragraph, the phrase "United States" means only the 50
        states and the District of Columbia, but does not
        include any territory or possession of the United
        States or any area over which the United States has
        asserted jurisdiction or claimed exclusive rights with
        respect to the exploration for or exploitation of
        natural resources.
            (C) Holding companies.
                (i) For purposes of this subparagraph, a
            "holding company" is a corporation (other than a
            corporation that is a financial organization under
            paragraph (8) of this subsection (a) of Section
            1501 because it is a bank holding company under the
            provisions of the Bank Holding Company Act of 1956
            (12 U.S.C. 1841, et seq.) or because it is owned by
            a bank or a bank holding company) that owns a
            controlling interest in one or more other
            taxpayers ("controlled taxpayers"); that, during
            the period that includes the taxable year and the 2
            immediately preceding taxable years or, if the
            corporation was formed during the current or
            immediately preceding taxable year, the taxable
            years in which the corporation has been in
            existence, derived substantially all its gross
            income from dividends, interest, rents, royalties,
            fees or other charges received from controlled
            taxpayers for the provision of services, and gains
            on the sale or other disposition of interests in
            controlled taxpayers or in property leased or
            licensed to controlled taxpayers or used by the
            taxpayer in providing services to controlled
            taxpayers; and that incurs no substantial expenses
            other than expenses (including interest and other
            costs of borrowing) incurred in connection with
            the acquisition and holding of interests in
            controlled taxpayers and in the provision of
            services to controlled taxpayers or in the leasing
            or licensing of property to controlled taxpayers.
                (ii) The income of a holding company which is a
            member of more than one unitary business group
            shall be included in each unitary business group of
            which it is a member on a pro rata basis, by
            including in each unitary business group that
            portion of the base income of the holding company
            that bears the same proportion to the total base
            income of the holding company as the gross receipts
            of the unitary business group bears to the combined
            gross receipts of all unitary business groups (in
            both cases without regard to the holding company)
            or on any other reasonable basis, consistently
            applied.
                (iii) A holding company shall apportion its
            business income under the subsection of Section
            304 used by the other members of its unitary
            business group. The apportionment factors of a
            holding company which would be a member of more
            than one unitary business group shall be included
            with the apportionment factors of each unitary
            business group of which it is a member on a pro
            rata basis using the same method used in clause
            (ii).
                (iv) The provisions of this subparagraph (C)
            are intended to clarify existing law.
            (D) If including the base income and factors of a
        holding company in more than one unitary business group
        under subparagraph (C) does not fairly reflect the
        degree of integration between the holding company and
        one or more of the unitary business groups, the
        dependence of the holding company and one or more of
        the unitary business groups upon each other, or the
        contributions between the holding company and one or
        more of the unitary business groups, the holding
        company may petition the Director, under the
        procedures provided under Section 304(f), for
        permission to include all base income and factors of
        the holding company only with members of a unitary
        business group apportioning their business income
        under one subsection of subsections (a), (b), (c), or
        (d) of Section 304. If the petition is granted, the
        holding company shall be included in a unitary business
        group only with persons apportioning their business
        income under the selected subsection of Section 304
        until the Director grants a petition of the holding
        company either to be included in more than one unitary
        business group under subparagraph (C) or to include its
        base income and factors only with members of a unitary
        business group apportioning their business income
        under a different subsection of Section 304.
            (E) If the unitary business group members'
        accounting periods differ, the common parent's
        accounting period or, if there is no common parent, the
        accounting period of the member that is expected to
        have, on a recurring basis, the greatest Illinois
        income tax liability must be used to determine whether
        to use the apportionment method provided in subsection
        (a) or subsection (h) of Section 304. The prohibition
        against membership in a unitary business group for
        taxpayers ordinarily required to apportion income
        under different subsections of Section 304 does not
        apply to taxpayers required to apportion income under
        subsection (a) and subsection (h) of Section 304. The
        provisions of this amendatory Act of 1998 apply to tax
        years ending on or after December 31, 1998.
        (28) Subchapter S corporation. The term "Subchapter S
    corporation" means a corporation for which there is in
    effect an election under Section 1362 of the Internal
    Revenue Code, or for which there is a federal election to
    opt out of the provisions of the Subchapter S Revision Act
    of 1982 and have applied instead the prior federal
    Subchapter S rules as in effect on July 1, 1982.
        (30) Foreign person. The term "foreign person" means
    any person who is a nonresident alien individual and any
    nonindividual entity, regardless of where created or
    organized, whose business activity outside the United
    States is 80% or more of the entity's total business
    activity.
 
    (b) Other definitions.
        (1) Words denoting number, gender, and so forth, when
    used in this Act, where not otherwise distinctly expressed
    or manifestly incompatible with the intent thereof:
            (A) Words importing the singular include and apply
        to several persons, parties or things;
            (B) Words importing the plural include the
        singular; and
            (C) Words importing the masculine gender include
        the feminine as well.
        (2) "Company" or "association" as including successors
    and assigns. The word "company" or "association", when used
    in reference to a corporation, shall be deemed to embrace
    the words "successors and assigns of such company or
    association", and in like manner as if these last-named
    words, or words of similar import, were expressed.
        (3) Other terms. Any term used in any Section of this
    Act with respect to the application of, or in connection
    with, the provisions of any other Section of this Act shall
    have the same meaning as in such other Section.
