Where, before the expiration of the time prescribed in this section for the assessment of tax, both the director and the taxpayer have consented in writing to its assessment after such time, the tax may be assessed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon.(3) Report of changed or corrected Federal income. If the taxpayer shall, pursuant to subsection a. of N.J.S. 54A:8-7, report a change or correction or file an amended return increasing the taxpayer's Federal taxable income or report a change or correction which is treated in the same manner as if it were a deficiency for Federal income tax purposes, the assessment (if not deemed to have been made upon the filing of the report or amended return) may be made at any time within 2 years after such report or amended return was filed. The amount of such assessment of tax shall not exceed the amount of the increase in New Jersey tax attributable to such Federal change or correction. The provisions of this paragraph shall not affect the time within which or the amount for which an assessment may otherwise be made.(4) Recovery of erroneous refund. An erroneous refund shall be considered an underpayment of tax on the date made, and an assessment of a deficiency arising out of an erroneous refund may be made at any time within 3 years from the making of the refund, except that the assessment may be made within 5 years from the making of the refund if it appears that any part of the refund was induced by fraud or misrepresentation of a material fact.(5) Request for prompt assessment. If a return is required for a decedent or for the decedent's estate during the period of administration, the tax shall be assessed within 18 months after written request therefor (made after the return is filed) by the executor, administrator or other person representing the estate of such decedent, but not more than 3 years after the return was filed, except as otherwise provided in this subsection and subsection (d).(6) Final federal adjustments resulting from a Federal Partnership Audit. Tax may be assessed against the partnership, direct or indirect partners, or both, within two years of the time that a partnership files a Federal Adjustments Report as required by N.J.S. 54A:8-7 that includes Final Federal Adjustments from a federal partnership audit or administrative adjustments request that would result in additional New Jersey income tax for one or more direct or indirect partners.(d) Omission of income on return.

For purposes of this subsection there shall not be taken into account any amount which is omitted in the return if such amount is disclosed in the return, or in a statement attached to the return, in a manner adequate to apprise the director of the nature and amount of such item.
(e) Suspension of running of period of limitation. The running of the period of limitations on assessment or collection of tax or other amount (or of a transferee's liability) shall, after the mailing of a notice of deficiency, be suspended for the period during which the director is prohibited under subsection (c) of section N.J.S. 54A:9-2 from making the assessment or from collecting by levy.Amended by L. 2022, c. 133, s. 4, eff. 12/22/2022.L.1976, c.47, s.54A:9-4, eff. 7/8/1976, operative 8/30/1976.
