What happens to a state net operating loss when the loss company merges out of existence?

The federal baseline the states start from

Section 381(a) provides that in a distribution to which section 332 applies (the liquidation of a subsidiary into its parent) and in a transfer to which section 361 applies "in connection with a reorganization described in subparagraph (A), (C), (D), (F), or (G) of section 368(a)(1)," the acquiring corporation succeeds to the transferor's tax items "as of the close of the day of distribution or transfer." Net operating loss carryovers are on the list (IRC section 381(c)(1)). The inherited losses are first used in "the first taxable year ending after the date of distribution or transfer," and in that year the deduction for them is limited to the share of the acquirer's taxable income that the post-transaction days bear to the full year (section 381(c)(1)(A), (B)). A loss the acquirer incurs after the transaction cannot be carried back to a pre-transaction year of the transferor (section 381(b)(3)).

Section 382 then limits the pace. After an "ownership change," meaning that the percentage of stock held by one or more 5-percent shareholders "has increased by more than 50 percentage points" within a three-year testing period (IRC section 382(g)(1), (i)(1)), the taxable income of the "new loss corporation" that can be offset by pre-change losses in any year is capped at the section 382 limitation, which is "the value of the old loss corporation, multiplied by" the long-term tax-exempt rate (section 382(a), (b)(1)). If the new loss corporation "does not continue the business enterprise of the old loss corporation at all times during the 2-year period" after the change, the limitation is generally zero (section 382(c)(1)).

Section 381 decides which corporation owns the loss after the transaction; section 382 decides how much of it can be used each year. A state can adopt one and reject the other. And because the federal rules assume one consolidated group with one loss pool, a state that taxes each corporation separately, or combines a different set of corporations, has to decide whose loss it is before any limitation question arises. That threshold question is where the states diverge.

Three state approaches

The states fall into three broad patterns, and the label a state gives its loss deduction is a poor predictor of which one it follows.

The loss follows the assets. A state whose loss deduction is tied to the federal computation, or whose statute or guidance imports sections 381 through 384, generally lets the surviving corporation step into the merged corporation's state loss, subject to the federal limits. New York's loss deduction instructions apply those limits, as discussed below.

The loss stays with the entity that generated it. A state that treats each corporation as a separate taxpayer and does not adopt section 381 lets the loss die with the corporation that incurred it. Tennessee is the clearest current example, and New Jersey generally applied the rule before its combined reporting regime began.

A hybrid. New Jersey now overrides section 381 by statute but carves out mergers within a New Jersey combined group, and it separately imports the federal merger limitations for the losses that do survive. The result depends on the parties' New Jersey filing posture around the merger date.

A second variable runs across all three patterns: whether the state measures its loss before or after apportionment. In a state that deducts the loss from income before apportionment, the inherited loss is effectively re-apportioned at the survivor's percentage in each year it is used, so the same dollar of loss can be worth more or less in the state depending on the survivor's footprint. In a state that measures the loss after apportionment, the loss is a fixed in-state amount at the moment it arises, and what passes in a merger (if anything passes) is that apportioned figure. New Jersey and New York both moved to the second model in their corporate reform years.

New Jersey: survival through the combined group

New Jersey's rule is statutory and turns on three subsections of N.J.S.A. 54:10A-4.5, as amended by P.L. 2020, c. 118, which was signed into law on November 4, 2020 (New Jersey Division of Taxation, TB-102(R), Net Operating Losses (NOLs) and Post Allocation Net Operating Losses (PNOLs) with Certain Mergers & Acquisitions (rev. April 20, 2023)).

The general rule overrides section 381. Subsection (a) begins "[n]otwithstanding any provision of subsection (k) of section 4 . . . or of the federal Internal Revenue Code, including but not limited to 26 U.S.C. s.381 or any successor or equivalent provision, that permits a corporation to use the net operating losses of another for federal income tax purposes following certain transactions," including reorganizations under section 368(a)(1)(A), (C), (D), (F) or (G). A New Jersey loss "may be carried over and allowed as a deduction only by the corporation that sustained the loss," and, in a merger under the law of any jurisdiction, "the net operating loss may be carried over only by the corporation that sustained the loss and that is also the surviving corporation following the merger." The subsection adds that the loss "may not be carried over by a taxpayer that changes its state of incorporation" (N.J.S.A. 54:10A-4.5(a)). Under that rule, the direction of the merger controls: a loss corporation that absorbs another corporation keeps its loss, and a loss corporation that merges into another corporation loses it.

The combined group exceptions. Subsection (b) provides that subsection (a) "shall not apply" in three cases: "(1) between members of a combined group reported on a combined return in New Jersey, or (2) between members of an affiliated group reported on the elective combined return in New Jersey, or (3) if corporations that were parties to the merger would be members of the combined group reported on a combined return in New Jersey within one group privilege period subsequent to the date of the merger," unless an unforeseen delay in required federal or other state regulatory approvals "delays the finality of the merger or acquisition" (N.J.S.A. 54:10A-4.5(b)). Paragraph (3) "shall only apply to mergers and acquisitions occurring on or after the effective date of P.L.2020, c.118" and "shall not apply to a binding agreement in effect prior to" that date (id.). The Division's illustration of paragraph (3) is a merger in Year 1: the parties "must file a New Jersey combined return together no later than for the Year 2 privilege period" (TB-102(R)).

The regulatory delay procedure. Where federal or other state regulatory approval delays the merger, "the corporations may petition the director, in a form and manner prescribed by the director," documenting their plan to be a combined group filing a New Jersey combined return once the approval is granted. Within 180 days after the approval, "the corporations shall notify the Division of Taxation of the approval and the director shall issue a stamped certificate of attestation attesting that the net operating loss carryovers are not extinguished" (N.J.S.A. 54:10A-4.5(b)). The Division states that only certificates bearing the Director's raised seal are valid (TB-102(R)).

Federal limitations apply to what survives. Subsection (c) provides that "[f]or privilege periods beginning on and after January 1, 2020," the federal rules "governing federal net operating losses, federal net operating loss carryovers with regard but not limited to: mergers, acquisitions, reorganizations, spin-offs, split-offs, dissolution, bankruptcy, or any form of cessation of a business, or any other provision that limits or reduces federal net operating losses" apply to New Jersey carryovers. The federal consolidated return rules apply to a combined group's carryovers "as though the combined group filed a federal consolidated return, regardless of how the members of the combined group filed for federal purposes," to the extent consistent with the Corporation Business Tax Act (N.J.S.A. 54:10A-4.5(c)). Read together, subsection (a) decides which corporation may carry the loss, subsection (b) lifts that bar inside a combined group, and subsection (c) imports section 382 and the consolidated return limits for the loss that remains.

New Jersey also has its own ownership change rule. Where "there is a change in 50% or more of the ownership of a corporation because of redemption or sale of stock and the corporation changes the trade or business giving rise to the loss, no net operating loss sustained before the changes may be carried over to be deducted from income earned after such changes," but the paragraph "shall not apply between members of a combined group reported on a New Jersey combined return" (N.J.S.A. 54:10A-4(v)(5); TB-94(R), General Information on the Net Operating Loss Regime for Tax Years Ending on and After July 31, 2019 (rev. October 11, 2023)).

What the loss is. For privilege periods ending on or after July 31, 2019, a New Jersey loss is measured after allocation, and it "shall be a net operating loss carryover to each of the twenty privilege periods following the period of the loss" (N.J.S.A. 54:10A-4(v)(1)). Losses from earlier periods were converted into a "prior net operating loss conversion carryover," a pre-allocation loss restated as a post-allocation amount using the taxpayer's base year allocation factor (N.J.S.A. 54:10A-4(u); TB-94(R)). A merger therefore carries, or extinguishes, two kinds of attribute, and both are subject to subsection (a).

Before the combined regime. According to the Division, before the 2018 and 2020 amendments the loss carryovers of a non-surviving entity generally did not survive a merger or acquisition. The 2018 legislation added the exception for combined group members; the Division notes that the statute then remained unclear for separate filers and separate combined groups, which paragraph (3) now addresses. For mergers entered into before November 4, 2020 by parties that had not filed together, the losses "may survive post-merger/acquisition depending on the facts and circumstances" (TB-102(R)).

A New Jersey example in three versions

A corporation that operates a regional distribution business (the loss company) has a New Jersey net operating loss carryover from three years of separate New Jersey returns. In March of Year 1, an unrelated corporation buys all of its stock.

In the first version, the buyer is the parent of a group that files a New Jersey combined return, the loss company's business is integrated with the group's and is unitary with it, and in September of Year 1 the loss company merges into a group member. Paragraph (3) of subsection (b) applies if the parties to the merger are members of the combined group reported on a New Jersey combined return within one group privilege period after the merger, which on the Division's reading means no later than the Year 2 return. If the group reports the loss company's pre-merger months on its Year 1 combined return, or the parties file together by Year 2, the loss is not extinguished. The surviving loss then carries forward subject to the federal consolidated return and section 382 limits under subsection (c).

In the second version, the buyer is in an unrelated line of business, its operations are not unitary with the loss company's, and the merger occurs in September of Year 1. The parties would not be members of one combined group, so no exception in subsection (b) applies. Subsection (a) lets only the corporation that sustained the loss carry it, and only if that corporation survives. The loss company did not survive, and the loss is extinguished for New Jersey purposes even though section 381 carries the federal loss to the buyer.

In the third version, the facts are those of the second, but the transaction is structured as a reverse merger: the buyer's acquisition subsidiary merges into the loss company, and the loss company survives. Subsection (a) is satisfied, because the corporation that sustained the loss is the surviving corporation. The loss is not free of limits, however. The stock purchase is an ownership change, so subsection (c) brings in the section 382 limitation, and if the loss company changes the trade or business that gave rise to the loss, the New Jersey ownership change rule of section 4(v)(5) bars the carryover outright for a corporation outside a combined group.

Tennessee: the loss belongs to the taxpayer that generated it

Tennessee's franchise and excise taxes generally treat each taxpayer as a separate entity, and the loss rule does not follow section 381. The statute, as the Department quotes it, provides that "a loss carryforward may be taken only by the taxpayer that generated it" (Tenn. Code Ann. section 67-4-2006(c)(2), quoted in Tennessee Department of Revenue Letter Ruling 20-06 (September 17, 2020)). The Department's manual applies it directly: "When there is a merger, consolidation, or like transaction the successor entity cannot use loss carryovers generated by a predecessor entity. When two or more businesses merge, only losses of the survivor corporation will be allowed" (Tennessee Department of Revenue, Franchise and Excise Tax Manual (June 2026), Survivability of NOLs). Loss carryovers run 15 years under the manual.

The exception is narrow. If a business merges into a shell entity, "where the successor is essentially the same taxpayer as the predecessor, then the successor entity may take a deduction for the predecessor's loss carryover," and a shell entity "is one that has no income, expenses, assets, liabilities, equity or net worth, or operations at the time of the restructuring" (id.; Tenn. Code Ann. section 67-4-2006(c)). Letter Ruling 20-06 shows how little room the exception leaves. Where several corporations merged into one newly formed corporation, only the first to merge could qualify, because once it merged the successor was no longer empty and the later corporations' losses "will be lost." Where corporations merged into an existing company that had its own loss, the exception failed, because a company that generated a loss had expenses and was not a shell (Letter Ruling 20-06).

Tennessee applies the same rule to transactions that are not mergers in form. The Department treats the conversion of a corporation into a single member LLC disregarded into a corporate owner as "tantamount to a merger" of the corporation into its owner (Tenn. Dep't of Revenue Rev. Rul. 07-14). If the owner is an operating company, it cannot use the converted corporation's losses. A reincorporation in another state through an F reorganization into a newly formed shell can preserve the loss (Franchise and Excise Tax Manual (June 2026)). A liquidating distribution followed by dissolution ends the loss: "its net operating losses do not survive the dissolution" (id.). Credits follow the same pattern, with the same shell exception (id.).

New York: an apportioned loss and a statute without a merger rule

New York's corporate franchise tax measures the loss after apportionment. "A net operating loss is the amount of a business loss incurred in a particular tax year, multiplied by the apportionment factor for that year," and the loss may be carried back three years (but not to a year beginning before January 1, 2015) and forward "for as many as twenty taxable years following the loss year" (N.Y. Tax Law section 210(1)(a)(ix), (ix)(4)). Losses from before 2015 were converted into a separate prior net operating loss conversion subtraction under section 210(1)(a)(viii), which runs for no more than 20 tax periods after 2015 and not into any tax year beginning on or after January 1, 2036 (Instructions for Form CT-3.3, Prior Net Operating Loss Conversion (PNOLC) Subtraction).

The statute contains no rule addressing a merged corporation's loss by name. Two of its provisions bear on the question. The deduction "shall not include any net operating loss incurred . . . during any taxable year in which the taxpayer was not subject to the tax imposed by this article" (Tax Law section 210(1)(a)(ix)(2)), and a corporation that is part of a federal consolidated return but files separately in New York "must compute its deduction and loss as if it were filing on a separate basis for federal income tax purposes" (section 210(1)(a)(ix)(3)). The Department's instructions supply the rest: a combined group computes its loss and deduction "as if the corporation had filed a consolidated return," carryovers from a combined year are "based on the combined NOL of the group," new and former members are scheduled separately, and losses limited by IRC sections 381 through 384 or the SRLY rules are shown as unavailable (Instructions for Form CT-3.4 (2025)). Under the PNOLC instructions, an entity that leaves or joins a combined group takes or brings its share of any unused subtraction with it.

That framework answers the common case: a loss corporation that merges into another member of the same New York combined group carries no separate attribute across the merger, because the loss already sits in the group's pool, subject to the federal limits. For a loss corporation that merges into a New York taxpayer from outside the group, the regulations determine the deduction "using the same limitations that would apply for Federal income tax purposes under the IRC and the related regulations regarding the NOLs of the acquired or merged loss companies," and limit the carryforward after a merger under the principles of IRC sections 381 through 384 (20 NYCRR 3-9.2(b), 3-9.6). How the "not subject to the tax" exclusion applies to a loss corporation that was never a New York taxpayer is less clear.

Practice notes

The state loss inventory belongs in diligence, not in the first post-closing return. For each state where the loss company has carryovers, the threshold question is whether the state lets a survivor inherit a merged corporation's loss at all; the second is whether the loss is measured before or after apportionment; and the third is which federal limits the state imports. In New Jersey, the decisive facts are the direction of the merger and whether the parties will appear together on a New Jersey combined return no later than the group privilege period after the merger year, and a merger that depends on regulatory approval is a candidate for the petition and certificate of attestation under N.J.S.A. 54:10A-4.5(b). In Tennessee, a merger into an operating company ends the loss, and the shell exception requires a successor that was empty at the time of the restructuring; a conversion into a disregarded LLC owned by an operating company is treated the same way. A reverse merger, in which the loss company survives, preserves the entity-level loss in both states but does not avoid section 382, which New Jersey imports for privilege periods beginning on and after January 1, 2020, or New Jersey's own ownership change and business change rule outside a combined group. Because Tennessee and New Jersey can both revisit a carryover that arose in a closed year when it is used in an open one (New Jersey within a statutory time limit), the merger history behind a loss schedule is reviewed along with the arithmetic.
