Illinois Statutes Chapter 35. Revenue § 620/2a.1. Imposition of tax on invested capital and on distribution of electricity

(a) In addition to the tax imposed by the Illinois Income Tax Act,  1 there is hereby imposed upon every taxpayer (other than an electric cooperative, a school district or unit of local government as defined in Section 1 of Article VII of the Illinois Constitution of 1970), an additional tax as follows:

(b) There is imposed on electric cooperatives that are required to file reports with the Rural Utilities Service a tax equal to 0.8% of such cooperative's invested capital for the taxable period. The invested capital tax imposed by this subsection shall not be imposed on electric cooperatives not required to file reports with the Rural Utilities Service.

(c) If, for any taxable period, the total amount received by the Department from the tax imposed by subsection (a) exceeds $145,279,553 plus, for taxable periods subsequent to 1998, an amount equal to the lesser of (i) 5% or (ii) the percentage increase in the Consumer Price Index during the immediately preceding taxable period, of the total amount received by the Department from the tax imposed by subsection (a) for the immediately preceding taxable period, determined after allowance of the credit provided for in this subsection, the Department shall issue credit memoranda in the aggregate amount of the excess to each of the taxpayers who paid any amount of tax under subsection (a) for that taxable period in the proportion which the amount paid by the taxpayer bears to the total amount paid by all such taxpayers. This calculation shall be made as of December 1 of the year following the immediately preceding taxable period and shall consist of only those returns with payment then on file with the Department. All future amendments to returns and monies covering this period received after December 1 of the year following the taxable period will not be included in the calculation of the affected taxable period or any other taxable period. The provisions of this subsection are not subject to the Uniform Penalty and Interest Act.  2 Any credit memorandum issued to a taxpayer under this subsection may be used as a credit by the taxpayer against its liability in future taxable periods for tax under subsection (a). Any amount credited to a taxpayer shall not be refunded to the taxpayer unless the taxpayer demonstrates to the reasonable satisfaction of the Department that it will not incur future liability for tax under subsection (a). The Department shall adopt reasonable regulations for the implementation of the provisions of this subsection.
