If the department of economic development determines the investment has been so approved, the department shall grant the tax credit in order of date received. A taxpayer may carry forward any unused tax credit for up to ten years and may carry it back for the previous three years until such credit has been fully claimed. Certificates of tax credit issued in accordance with this section may be transferred, sold or assigned by notarized endorsement which names the transferee. The tax credits allowed pursuant to this section shall be for an amount of no more than ten million dollars for each year. This credit shall apply to returns filed for all taxable years beginning on or after January 1, 1999.

For purposes of this section, a "taxpayer" shall include any charitable organization that is exempt from federal income tax and whose Missouri unrelated business taxable income, if any, would be subject to the state income tax imposed under chapter 143.
