If the amount of a taxpayer’s federal taxable income, total taxable amount or ordinary income portion of a lump sum distribution or includible gain of a trust reported on their federal income tax return for any taxable year, or the amount of a taxpayer’s earned income credit or credit for employment-related expenses set forth on such return, or the amount of any federal foreign tax credit affecting the calculation of the credit for Canadian provincial taxes under section six hundred twenty or six hundred twenty-A of this article, or the amount of any claim of right adjustment, 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 the amount an employer is required to deduct and withhold from wages for federal income tax withholding purposes is changed or corrected by such service or authority or if a taxpayer’s claim for credit or refund of federal income tax is disallowed in whole or in part, the taxpayer or employer shall report such change or correction or disallowance within ninety days after the final determination of such change, correction, renegotiation or disallowance, or as otherwise required by the commissioner, and shall concede the accuracy of such determination or state wherein it is erroneous. Provided, however, if the taxpayer is a direct or indirect partner of a partnership required to report adjustments in accordance with § 659-A (Reporting of federal partnership adjustments)section six hundred fifty-nine-a of this part, such taxpayer shall also report such adjustments in accordance with § 659-A (Reporting of federal partnership adjustments)section six hundred fifty-nine-a of this part. The allowance of a tentative carryback adjustment based upon a net operating loss carryback pursuant to section sixty-four hundred eleven of the internal revenue code shall be treated as a final determination for purposes of this section. Any taxpayer filing an amended federal income tax return and any employer filing an amended federal return of income tax withheld shall also file within ninety days thereafter an amended return under this article, and shall give such information as the commissioner may require. The commissioner may by regulation prescribe such exceptions to the requirements of this section as they deem appropriate. For purposes of this section, (i) the term “taxpayer” shall include a partnership having a resident partner or having any income derived from New York sources, and a corporation with respect to which the taxable year of such change, correction, disallowance or amendment is a year with respect to which the election provided for in subsection (a) of § 660 (Election by shareholders of S corporations)section six hundred sixty of this article is in effect, and

(ii)

the term “federal income tax return” shall include the returns of income required under sections six thousand thirty-one and six thousand thirty-seven of the internal revenue code. In the case of such a corporation, such report shall also include any change or correction of the taxes described in paragraphs two and three of subsection (f) of section thirteen hundred sixty-six of the internal revenue code. Reports made under this section by a partnership or corporation shall indicate the portion of the change in each item of income, gain, loss or deduction (and, in the case of a corporation, of each change in, or disallowance of a claim for credit or refund of, a tax referred to in the preceding sentence) allocable to each partner or shareholder and shall set forth such identifying information with respect to such partner or shareholder as may be prescribed by the commissioner.
