N.Y. General City Law art. 2-D, § 39: Report of change in federal taxable income

§ 39. Report of change in federal taxable income.--If the amount of a

taxpayer's federal taxable income reported on his federal income tax

return for any taxable year is changed or corrected by the United States

internal revenue service or other competent authority, or as the result

of a renegotiation of a contract or subcontract with the United States

or if a taxpayer, pursuant to subsection (d) of section six thousand two

hundred thirteen of the internal revenue code, executes a notice of

waiver of the restrictions provided in subsection (a) of said section,

the taxpayer shall report such change or correction in federal taxable

income or such execution of such notice of waiver and the changes or

corrections of his federal taxable income on which it is based, within

ninety days after the final determination of such change, correction, or

renegotiation, or such execution of such notice of waiver or as

otherwise required by the administrator, and shall concede the accuracy

of such determination or state wherein it is erroneous. Any taxpayer

filing an amended federal income tax return shall also file within

ninety days thereafter an amended return under this local law, and shall

give such information as the administrator may require. The

administrator may by regulation prescribe such exceptions to the

requirements of this section as he deems appropriate.
