Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (35 ILCS 10/5-45)
    Sec. 5-45. Amount and duration of the credit.
    (a) The Department shall determine the amount and duration of the credit awarded under this Act. The duration of the credit may not exceed 10 taxable years for projects qualified under paragraph (1), (1.5), or (1.6) of subsection (b) of Section 5-20 or 15 taxable years for projects qualified under paragraph (1.7) of subsection (b) of Section 5-20. The credit may be stated as a percentage of the Incremental Income Tax attributable to the applicant's project and may include a fixed dollar limitation.
    (b) Notwithstanding subsection (a), and except as the credit may be applied in a carryover year pursuant to Section 211(4) of the Illinois Income Tax Act, the credit may be applied against the State income tax liability in more than 10 taxable years but not in more than 15 taxable years for an eligible business that (i) qualifies under this Act and the Corporate Headquarters Relocation Act and has in fact undertaken a qualifying project within the time frame specified by the Department of Commerce and Economic Opportunity under that Act, and (ii) applies against its State income tax liability, during the entire 15-year period, no more than 60% of the maximum credit per year that would otherwise be available under this Act.
    (c) Nothing in this Section shall prevent the Department, in consultation with the Department of Revenue, from adopting rules to extend the sunset of any earned, existing, and unused tax credit or credits a taxpayer may be in possession of, as provided for in Section 605-1070 of the Department of Commerce and Economic Opportunity Law of the Civil Administrative Code of Illinois, notwithstanding the carry-forward provisions pursuant to paragraph (4) of Section 211 of the Illinois Income Tax Act.
