(f) Earned income tax credit. (1) Notwithstanding any other provision of law to the contrary, any city having a population of one million or more, acting through its local legislative body, is hereby authorized and empowered to adopt and amend local laws granting in any such city, for taxable years beginning after two thousand three, a credit against the city personal income tax equal to five percent of the earned income credit allowed under section thirty-two of the internal revenue code for the same taxable year, and, for taxable years beginning after two thousand twenty-one, a credit against the city personal income tax equal to a percentage, determined pursuant to subparagraphs (A) through (I) of this paragraph, of the earned income credit allowed under section thirty-two of the internal revenue code for the same taxable year. For purposes of this paragraph, "adjusted gross income" means New York adjusted gross income as determined pursuant to article twenty-two of this chapter. The percentage shall be:
- (A) thirty percent, where the taxpayer's adjusted gross income for such taxable year is less than $5,000;
- (B) thirty percent reduced by the product of two-tenths of a percentage point (0.002) and the amount of the taxpayer's adjusted gross income for such taxable year in excess of $4,999, where such taxpayer's adjusted gross income for such taxable year is equal to or greater than $5,000 and less than $7,500;
- (C) twenty-five percent, where the taxpayer's adjusted gross income for such taxable year is equal to or greater than $7,500 and less than $15,000;
- (D) twenty-five percent reduced by the product of two-tenths of a percentage point (0.002) and the amount of the taxpayer's adjusted gross income for such taxable year in excess of $14,999, where such taxpayer's adjusted gross income for such taxable year is equal to or greater than $15,000 and less than $17,500;
- (E) twenty percent, where the taxpayer's adjusted gross income for such taxable year is equal to or greater than $17,500 and less than $20,000;
- (F) twenty percent reduced by the product of two-tenths of a percentage point (0.002) and the amount of the taxpayer's adjusted gross income for such taxable year in excess of $19,999, where such taxpayer's adjusted gross income for such taxable year is equal to or greater than $20,000 and less than $22,500;
- (G) fifteen percent, where the taxpayer's adjusted gross income for such taxable year is equal to or greater than $22,500 and less than $40,000;
- (H) fifteen percent reduced by the product of two-tenths of a percentage point (0.002) and the amount of the taxpayer's adjusted gross income for such taxable year in excess of $39,999, where such taxpayer's adjusted gross income for such taxable year is equal to or greater than $40,000 and less than $42,500; and
- (I) ten percent where the taxpayer's adjusted gross income for such taxable year is equal to or greater than $42,500.
- (2) In the case of a resident taxpayer, the credit provided by local law adopted pursuant to this subsection shall be allowed against the taxes authorized by this article for the taxable year reduced by the credits permitted by this article. If the credit exceeds the tax as so reduced, the taxpayer may receive, and the comptroller, subject to a certificate of the commissioner, shall pay as an overpayment, without interest, the amount of such excess.
- (3) If a taxpayer changes his or her status during the taxable year from city resident to city nonresident, or from city nonresident to city resident, the credit determined under this subsection shall be limited to the amount determined by multiplying the amount of such credit by a fraction, the numerator of which is such taxpayer's city adjusted gross income, as defined in chapter seventeen of title eleven of the administrative code of the city of New York, for the period of residence, and the denominator of which is such taxpayer's city adjusted gross income determined as if he or she were a city resident for the entire taxable year. City adjusted gross income shall be adjusted as provided in section 11-1754 of the administrative code of the city of New York. The credit as so limited shall be applied as provided in paragraph two of this subsection.
- (4) Subject to the provisions of paragraph three of this subsection, in the case of a husband and wife who file a joint return, but who are required to determine their city personal income taxes separately, the credit authorized pursuant to this subsection may be applied against the tax of either or divided between them as they may elect. In the case of a husband and wife who are not required to file a federal return, the credit under this subsection shall be allowed only if such taxpayers file a joint city personal income tax return.
- (5) A local law enacted pursuant to this subsection shall be applicable with respect to any taxable year only if it has been enacted on or before the date that is forty-five days after the effective date of this subsection and for taxable years subsequent to taxable year two thousand four, on or before July thirty-first of such taxable year. A certified copy of such local law shall be mailed by registered mail to the state department of taxation and finance at its office in Albany within fifteen days of its enactment. However, the state department of taxation and finance 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.
- (6) If the department determines that the taxpayer is eligible to receive the credit provided under this subsection but has not claimed such credit on his or her return, the department shall compute and issue any refund for the allowable credit amount provided under this subsection. Any refund paid pursuant to this paragraph shall be deemed to be a refund of an overpayment of tax as provided in section six hundred eighty-six of this chapter, provided, however, that no interest shall be paid thereon.
