1. Notwithstanding any other provision of Missouri law, some portion of the tax credits earned by a newly established new business facility within an enterprise zone through the provisions of sections 135.200 to 135.256, except one designated pursuant to subsection 5 of section 135.230, which exceeds its total income tax liability shall be considered an overpayment of the income tax and shall be refunded to the taxpayer as provided by this section, except that such refund shall only apply to taxpayers subject to the tax imposed pursuant to chapter 143. The refund allowed by this section shall be limited to taxpayers who establish new facilities in enterprise zones. The refund shall not be allowed to a taxpayer who establishes a new business facility because it qualifies as a separate facility pursuant to subsection 6 of section 135.110 or subdivision (7) of subsection 1 of section 135.225 or because it satisfies the requirements of paragraph (c) of subdivision (5)^* of section 135.100 or subdivision (11)^* of section 135.100. The provisions of this section shall have effect on all initial applications filed on or after August 28, 1992. The provisions of this section shall only be available to a taxpayer for the first two consecutive years during which the taxpayer is eligible for the credits provided by sections 135.200 to 135.256, and the portion of tax credit which is considered an overpayment of the income tax shall be limited to fifty percent or fifty thousand dollars, whichever is less, in the first year and twenty-five percent or twenty-five thousand dollars, whichever is less, in the second year in which the taxpayer is eligible. The overpayment of the income tax for the first year shall not be refunded to the taxpayer until the third taxable year of operation by the new business facility and the overpayment of the income tax for the second year shall not be refunded to the taxpayer until the fourth taxable year of operation by the new business facility.

2. The portion of tax credit which is considered an overpayment of the income tax by any taxpayer who establishes a new business facility in an enterprise zone designated pursuant to subsection 5 of section 135.230 shall be limited to twenty-five percent or twenty-five thousand dollars, whichever is less, in the first year of the ensuing seven-year period. Such overpayment of tax shall not be refunded to the taxpayer until the third taxable year of operation by the new business facility.

3. Such refunds to the taxpayer shall be made as otherwise provided by law. In the case of a small corporation described in section 143.471 or a partnership, all refunds allowed by this section shall be apportioned in proportion to the share of ownership of the business on the last day of the taxpayer’s tax period for which such tax credits are being claimed, to the following:

(1) The shareholders of the corporation described in section 143.471; or

(2) The partners in a partnership.
