§ 15-129. Report of change in taxable income.

If the amount of a taxpayer's federal or New York State taxable income
or self-employment income reported on his/her federal or New York State
Tax return for any taxable year is changed or corrected by the United
States Internal Revenue Service or the New York State Tax Commission or
other competent authority, or as the result of a renegotiation of a
contract or subcontract with the United States or New York State or if a
taxpayer, pursuant to Subsection (d) of Section 6213 of the Internal
Revenue Code, executing a notice of waiver of the restrictions provided
in Subsection (a) of said section, or if a taxpayer, pursuant to § 681,
Subdivision (f), of the New York State Tax Law executes a notice of
waiver of the restrictions provided in Subdivision (c) of said section,
or if any tax on self-employment income in addition to that shown on
his/her return is assessed, the taxpayer shall report such change or
correction in federal or New York State taxable income or such execution
of such notice of waiver or such assessment and the changes or
corrections of his/her federal or New York State taxable income or
self-employment income on which it is based, within ninety (90) days
after the final determination of such change, correction or
renegotiation or such execution of such notice of waiver or the making
of such assessment as otherwise required by the State Tax Commission and
shall concede the accuracy of such determination or state wherein it is
erroneous. Any taxpayer filing an amended federal or New York State
income or self-employment income tax return shall also file within
ninety (90) days thereafter an amended return under this article and
shall give such information as the State Tax Commission may require. The
State Tax Commission may, by regulation, prescribe such exceptions to
the requirements of this section as it deems appropriate.
