[In cases involving an economic development project for which the Mississippi Business Finance Corporation has not issued bonds for the purpose of financing the approved costs of such project prior to July 1, 1997, or in cases involving an economic development project which has not been induced by a resolution of the Board of Directors of the Mississippi Business Finance Corporation that has been filed with the State Tax Commission prior to July 1, 1997, this section shall read as follows:]

For any approved company as defined in Section 57-10-401, there shall be allowed against the taxes imposed by this chapter on the income of the approved company generated by or arising out of the economic development project (as defined in Section 57-10-401), a credit in an amount not to exceed the total debt service paid under a financing agreement entered into under Section 57-10-409; provided, however, that the tax credit allowed in this subsection shall not exceed eighty percent (80%) of the amount of taxes due the State of Mississippi prior to the application of the credit. To the extent that financing agreement annual payments exceed the amount of the credit authorized pursuant to this section in any taxable year, such excess payment may be recouped from excess credits in succeeding years not to exceed three (3) years following the date upon which the credit was earned. The amount of income of the approved company generated by or arising out of the economic development project shall be determined by a formula adopted by the Mississippi Business Finance Corporation.
