A taxpayer who has been awarded a credit by the Department of Commerce and Economic Opportunity under Section 605-1115 of the Department of Commerce and Economic Opportunity Law of the Civil Administrative Code of Illinois is entitled to a credit against the taxes imposed under subsections (a) and (b) of Section 201 of this Act. The amount of the credit shall be 20% of the wages paid by the taxpayer during the taxable year to a full-time or part-time employee of a construction contractor employed in the construction of an eligible facility located on a quantum computing campus designated under Section 605-1115 of the Department of Commerce and Economic Opportunity Law of the Civil Administrative Code of Illinois.

In no event shall a credit under this Section reduce the taxpayer's liability to less than zero. 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.
