N.Y. Tax Law § 187-C
A taxpayer shall be allowed a credit to be computed as provided in section twenty-eight of this chapter, as added by part X of chapter sixty-two of the laws of two thousand six, against the tax imposed by this article. Provided, however, that the amount of such credit allowed against the tax imposed by section one hundred eighty-four of this article shall be the excess of the amount of such credit over the amount of any credit allowed by this section against the tax imposed by section one hundred eighty-three of this article. In no event shall the credit under this section be allowed in an amount which will reduce the tax payable to less than the applicable minimum tax fixed by section one hundred eighty-three of this article. If, however, the amount of the credit allowed under this section for any taxable year reduces the tax to such amount, the excess shall be treated as an overpayment of tax to be credited or refunded in accordance with the provisions of section six hundred eighty-six of this chapter. Provided, however, the provisions of subsection (c) of section one thousand eighty-eight of this chapter notwithstanding, no interest shall be paid thereon. The tax credit allowed pursuant to this section shall apply to taxable years beginning before January first, two thousand twenty.
