New Jersey Statutes Title 54A. New Jersey Gross Income Tax Act 54A § 8-7

a. Report of change in federal taxable income or credit. If the amount of a taxpayer's federal taxable income or earned income tax credit reported on the taxpayer's 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, the taxpayer shall report such change or correction in federal taxable income or earned income tax credit within 90 days after the final determination of such change, correction, or renegotiation, or as otherwise required by the director, and shall concede the accuracy of such determination or state wherein it is erroneous. Any taxpayer filing an amended federal income tax return, including a return or other information filed pursuant to section 6225(c) of the Internal Revenue Code (26 U.S.C. s. 6225(c)), shall also file within 90 days thereafter an amended return under this act, and shall give such information as the director may require. The director may by regulation prescribe such exceptions to the requirements of this section as the director deems appropriate.

b. A partnership shall report the Final Federal Adjustments from a federal partnership audit or administrative adjustment request pursuant to section 6225(a)(1) of the Internal Revenue Code (26 U.S.C. s.6225(a)(1)) by filing the Federal Adjustments Report as prescribed by the director within 90 days after the Final Determination Date of the federal adjustments arising from a partnership-level audit.

c. The director may assess the federally audited partnership, partners, or both, for taxes they owe, using the best information available, even if the partnership or tiered partner fails to timely make any report required by this section for any reason.

d. The director shall adopt rules and regulations the director may deem necessary to effectuate the provisions of this section.
