    AN ACT concerning revenue.
 
    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 304, 502, and 709.5 as follows:
 
    (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.
    (3) Sales factor.
        (A) The sales factor is a fraction, the numerator of
    which is the total sales of the person in this State during
    the taxable year, and the denominator of which is the total
    sales of the person everywhere during the taxable year.
        (B) Sales of tangible personal property are in this
    State if:
            (i) The property is delivered or shipped to a
        purchaser, other than the United States government,
        within this State regardless of the f. o. b. point or
        other conditions of the sale; or
            (ii) The property is shipped from an office, store,
        warehouse, factory or other place of storage in this
        State and either the purchaser is the United States
        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
        business activity outside of the United States and the
        property is purchased for resale.
        (B-1) Patents, copyrights, trademarks, and similar
    items of intangible personal property.
            (i) Gross receipts from the licensing, sale, or
        other disposition of a patent, copyright, trademark,
        or similar item of intangible personal property, other

        utilized in this State during the year the gross
        receipts are included in gross income.
            (ii) Place of utilization.
                (I) A patent is utilized in a state to the
            extent that it is employed in production,
            fabrication, manufacturing, or other processing in
            the state or to the extent that a patented product
            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
            domicile of the licensee or purchaser is located.
            (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
        receipts attributable to that item shall be excluded
        from both the numerator and the denominator of the
        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.
        (B-5) For taxable years ending on or after December 31,

        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
        year to year for this purpose and fairly represents the
        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
        airwaves, by cable, by direct or indirect satellite
        transmission, or by any other means of communication,
        either through a station, a network, or a cable system.
            "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,
        commercial, educational, or artistic works, either
        live or through the use of video tape, disc, or any
        other type of format or medium. Each episode of a
        series of films produced for television shall
        constitute separate "film" notwithstanding that the
        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
        live or through the use of an audio tape, disc, or any
        other format or medium. Each episode in a series of
        radio programming produced for radio broadcast shall
        constitute a separate "radio programming"
        notwithstanding that the series relates to the same
        principal subject and is produced during one or more
        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,
            or a cable system for a fee or other remuneration
            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
            programming is provided by a taxpayer that is a
            network or station to a customer for broadcast in
            exchange for a fee or other remuneration from that
            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.
        (C) For taxable years ending before December 31, 2008,
    sales, other than sales governed by paragraphs (B), (B-1),
    and (B-2), are in this State if:
            (i) The income-producing activity is performed in
        this State; or
            (ii) The income-producing activity is performed
        both within and without this State and a greater
        proportion of the income-producing activity is
        performed within this State than without this State,
        based on performance costs.
        (C-5) For taxable years ending on or after December 31,
    2008, sales, other than sales governed by paragraphs (B),
    (B-1), (B-2), (B-5), and (B-7), are in this State if any of
    the following criteria are met:
            (i) Sales from the sale or lease of real property
        are in this State if the property is located in this
        State.
            (ii) Sales from the lease or rental of tangible
        personal property are in this State if the property is
        located in this State during the rental period. Sales
        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 in this
        State to the extent that the property is used in this
        State.
            (iii) In the case of interest, net gains (but not
        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 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.

        (5) (Blank).
    (c-1) Federally regulated exchanges. For taxable years
ending on or after December 31, 2012, business income of a
federally regulated exchange shall, at the option of the
federally regulated exchange, 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 purposes of this subsection, the business income within
this State of a federally regulated exchange is the sum of the
following:
        (1) Receipts attributable to transactions executed on
    a physical trading floor if that physical trading floor is
    located in this State.
        (2) Receipts attributable to all other matching,
    execution, or clearing transactions, including without
    limitation receipts from the provision of matching,
    execution, or clearing services to another entity,
    multiplied by (i) for taxable years ending on or after
    December 31, 2012 but before December 31, 2013, 63.77%; and
    (ii) for taxable years ending on or after December 31,
    2013, 27.54%.
        (3) All other receipts not governed by subparagraphs
    (1) or (2) of this subsection (c-1), to the extent the
    receipts would be characterized as "sales in this State"
    under item (3) of subsection (a) of this Section.
    "Federally regulated exchange" means (i) a "registered
entity" within the meaning of 7 U.S.C. Section 1a(40)(A), (B),
or (C), (ii) an "exchange" or "clearing agency" within the
meaning of 15 U.S.C. Section 78c (a)(1) or (23), (iii) any such
entities regulated under any successor regulatory structure to
the foregoing, and (iv) all taxpayers who are members of the
same unitary business group as a federally regulated exchange,
determined without regard to the prohibition in Section
1501(a)(27) of this Act against including in a unitary business
group taxpayers who are ordinarily required to apportion
business income under different subsections of this Section;
provided that this subparagraph (iv) shall apply only if 50% or
more of the business receipts of the unitary business group
determined by application of this subparagraph (iv) for the
taxable year are attributable to the matching, execution, or
clearing of transactions conducted by an entity described in
subparagraph (i), (ii), or (iii) of this paragraph.
    In no event shall the Illinois apportionment percentage
computed in accordance with this subsection (c-1) for any
taxpayer for any tax year be less than the Illinois
apportionment percentage computed under this subsection (c-1)
for that taxpayer for the first full tax year ending on or
after December 31, 2013 for which this subsection (c-1) applied
to the taxpayer.
    (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, for taxable years ending before December
31, 2008, fairly represent the extent of a person's business
activity in this State, or, for taxable years ending on or
after December 31, 2008, fairly represent the market for the
person's goods, services, or other sources of business income,
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 or market 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
percentage weight given to each factor whose denominator is
equal to zero.

    (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, 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) For taxable years ending prior to December 31, 2014,
the 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. For taxable years ending prior
to December 31, 2014, the 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 and ending prior to
December 31, 2014.
    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 5/709.5)
    Sec. 709.5. Withholding by partnerships, Subchapter S
corporations, and trusts.
    (a) In general. For each taxable year ending on or after
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,
shareholder, or beneficiary (other than a partner,
shareholder, or beneficiary who is exempt from tax under
Section 501(a) of the Internal Revenue Code or under Section
205 of this Act, who is included on a composite return filed by
the partnership or Subchapter S corporation for the taxable
year under subsection (f) of Section 502 of this Act), or who
is a retired partner, to the extent that partner's
distributions are exempt from tax under Section 203(a)(2)(F) of
this Act) an amount equal to the sum distributable share of (i)
the share of business income of the partnership, Subchapter S
corporation, or trust apportionable to Illinois plus (ii) for
taxable years ending on or after December 31, 2014, the share
of nonbusiness income of the partnership, Subchapter S
corporation, or trust allocated to Illinois under Section 303
of this Act (other than an amount allocated to the commercial
domicile of the taxpayer under Section 303 of this Act) that is
distributable to of that partner, shareholder, or beneficiary
under Sections 702 and 704 and Subchapter S of the Internal
Revenue Code, whether or not distributed, (iii) multiplied by
the applicable rates of tax for that partner, or shareholder,
or beneficiary under subsections (a) through (d) of Section 201
of this Act, and (iv) net of the share of any credit under
Article 2 of this Act that is distributable by the partnership,
Subchapter S corporation, or trust and allowable against the
tax liability of that partner, shareholder, or beneficiary for
a taxable year ending on or after December 31, 2014.
    (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
