§ 1304-B. Additional tax. (a) (1) In addition to any other taxes authorized by this article, any city imposing such taxes is hereby authorized and empowered to adopt and amend local laws imposing in any such city for each taxable year beginning after nineteen hundred ninety but before two thousand twenty-four, an additional tax on the city taxable income of every city resident individual, estate and trust, to be calculated for each taxable year as follows: (i) for each taxable year beginning after nineteen hundred ninety but before nineteen hundred ninety-nine, at the rate of fourteen percent of the sum of the taxes for each such taxable year determined pursuant to section thirteen hundred four and section thirteen hundred four-A of this article; and (ii) for each taxable year beginning after nineteen hundred ninety-eight, at the rate of fourteen percent of the tax for such taxable year determined pursuant to such section thirteen hundred four.

(2) Notwithstanding paragraph one of this subsection, for each taxable year beginning after nineteen hundred ninety-nine but before two thousand twenty-four, any city imposing such additional tax may by local law impose such tax at a rate that is less than fourteen percent and may impose such tax at more than one rate depending upon the filing status and city taxable income of such city resident individual, estate or trust.

(3) A local law enacted pursuant to paragraph two of this subsection shall be applicable with respect to any taxable year only if it has been enacted on or before July thirty-first of such year. A certified copy of such local law shall be mailed by registered mail to the department at its office in Albany within fifteen days of its enactment. However, the department may allow additional time for such certified copy to be mailed if it deems such action to be consistent with its duties under this article.

(b) The additional tax imposed pursuant to the authority of this section shall be administered, collected and distributed by the commissioner of taxation and finance in the same manner as the other taxes imposed pursuant to the authority of this article, and all of the provisions of this article, including section thirteen hundred ten of this article, shall apply to the additional tax authorized by this section.
