Tax-Free Corporate Reorganizations (§ 368)

26 U.S.C. § 368 defines seven categories of corporate reorganizations that qualify for tax-free — or more precisely, tax-deferred — treatment, allowing corporations to merge, acquire, or restructure without triggering immediate gain recognition for the corporation or for shareholders who receive stock in the surviving entity. The logic is continuity: when a shareholder exchanges Target Corp. stock for Acquirer Corp. stock in a qualifying reorganization, their investment has not fundamentally changed — they still hold equity in essentially the same enterprise. The statute defers, rather than forgives, the pre-reorganization gain; the shareholder's basis in the new stock reflects their original investment, and the gain survives until the new shares are eventually sold. The quid pro quo for tax-free treatment is that shareholders must receive primarily stock — not cash — and the historical business and investment must continue forward in the surviving entity. When these conditions hold, § 368 is the foundational statute for M&A, enabling mergers of equals, bolt-on acquisitions, and corporate restructurings without a tax penalty on either party.

Current Law (2026)

§ 368 defines the qualifying reorganization types. Tax-free treatment requires meeting the statutory type requirements plus three judicial doctrines.

Judicial doctrines (required in all types):

• Continuity of Interest (COI): Shareholders must receive meaningful equity consideration (≥40% of total consideration)
• Continuity of Business Enterprise (COBE): Acquirer must continue the target's historic business or use a significant portion of its assets
• Business Purpose: Transaction must serve a genuine non-tax corporate purpose

Legal Authority

• 26 U.S.C. § 368 — Definitions relating to corporate reorganizations (the seven reorganization types)
• 26 U.S.C. § 354 — Exchanges of stock and securities in certain reorganizations (shareholder non-recognition)
• 26 U.S.C. § 361 — Nonrecognition of gain or loss to corporations (corporate-level non-recognition)
• 26 U.S.C. § 356 — Receipt of additional consideration (boot rules — gain recognized to extent of boot received)
• 26 U.S.C. § 358 — Basis to distributees (shareholder's basis in new stock after reorganization)
• 26 U.S.C. § 362 — Basis to corporations (acquiring corporation's basis in acquired assets or stock)
• 26 U.S.C. § 368 (DB) — Definitions relating to corporate reorganizations: investment companies are generally excluded from reorganization treatment unless they are regulated investment companies, REITs, or meet special diversification tests (no more than 25% of assets in one issuer and no more than 50% in five or fewer issuers); if a deal fits both the stock-for-assets and the asset-transfer tests, it is treated as the asset-transfer type; moving acquired assets or stock into a controlled subsidiary does not automatically defeat qualification; "control" means owning at least 80% of voting power and at least 80% of other shares
• 26 U.S.C. § 354 (DB) — Exchanges of stock and securities in certain reorganizations: the nonrecognition rule does not apply if the principal amount of securities received exceeds securities surrendered, or if securities are received and none surrendered; for reorganizations that transfer assets, the rule applies only if the new company takes substantially all the transferor's assets and the transferor distributes what it receives under the plan; a confirmed railroad reorganization qualifies even if it would not otherwise meet the requirements
• 26 U.S.C. § 361 (DB) — Nonrecognition of gain or loss to corporations: if the reorganizing corporation receives other property or money, it must pass those proceeds to shareholders or creditors under the plan to avoid recognizing gain; a corporation cannot claim a loss on the exchange of other property; transfers of qualified property to creditors are treated as distributions to shareholders

Key Mechanics

Section 368 reorganizations achieve tax-free treatment for qualifying corporate combinations through a deemed-continuity approach: shareholders receiving stock in the acquirer are treated as exchanging one equity interest for another, not as selling their investment, so no gain or loss is recognized at the time of the transaction. Three judicial doctrines govern eligibility regardless of the statutory type: (1) continuity of interest — at least 40% of total consideration must be acquirer stock (not cash or debt); (2) continuity of business enterprise — the acquiring corporation must continue the target's historic business or use a significant portion of the target's business assets for at least 2 years; and (3) business purpose — the reorganization must have a genuine business reason beyond mere tax avoidance. The reorganization types (A through G) differ primarily in what form of legal transaction qualifies, what consideration is permitted, and which corporate parties can participate.

How It Works

Type A — Statutory Merger is the most flexible reorganization. One corporation merges into another under state law, and the target ceases to exist. Because Type A requires only that the transaction qualify as a "merger or consolidation" under applicable state or foreign law, it permits the broadest range of consideration: cash, notes, stock, and other property can all be used, as long as the continuity-of-interest doctrine is satisfied (generally requiring at least 40% of total consideration to be acquirer stock). Triangle mergers — where a subsidiary of the acquirer merges with the target rather than the acquirer itself — are permitted under § 368(a)(2)(D) (forward triangle merger) and § 368(a)(2)(E) (reverse triangle merger), allowing the acquirer's parent to maintain separation from the target's liabilities while still achieving tax-free treatment.

Type B — Stock-for-Stock is the strictest. The acquirer must obtain control (80% of vote and value) of the target solely in exchange for its voting stock. Zero cash, notes, or other consideration is permitted — even a single dollar of cash paid to any target shareholder taints the entire transaction and disqualifies it from Type B treatment. The "solely for voting stock" requirement is absolute. This rigidity makes Type B transactions relatively uncommon for large acquisitions but useful for acquisitions of 80%-controlled subsidiaries.

Type C — Stock-for-Assets allows the acquirer to purchase substantially all of the target's assets using primarily voting stock. "Substantially all" has been interpreted by the IRS as at least 70% of fair market value of gross assets and 90% of net assets. Up to 20% of the total consideration can be non-stock (cash, notes, assumption of liabilities), but liabilities assumed count against the 20% boot limit. After the asset transfer, the target must distribute all assets (including the acquirer stock it received) to its shareholders in liquidation — the target disappears. Type C is more complex operationally than a Type A merger but allows the acquirer to cherry-pick assets rather than acquiring the target as a legal entity with all its liabilities.

Boot and gain recognition: In any § 368 reorganization, shareholders who receive boot — cash or other non-stock consideration — recognize gain to the extent of the boot received, limited to their total realized gain. If the boot has the character of a dividend (the "dividend-within-gain" rule of § 356(a)(2)), it is taxed as ordinary income rather than capital gain. The acquiring corporation and the target corporation generally do not recognize gain in a qualifying reorganization, even on appreciated assets transferred.

The § 338(h)(10) alternative: When a § 368 reorganization is unavailable or the parties prefer asset-purchase economics, the § 338(h)(10) election allows a stock purchase to be treated as an asset purchase for tax purposes — see the § 338 Election page.

How It Affects You

If you're a shareholder of a company being acquired in a stock-for-stock merger: If the merger qualifies under § 368 (look for the company's press release or proxy statement — it will say "intended to qualify as a tax-free reorganization"), you do not recognize gain when you exchange your target shares for acquirer shares. Your basis in the new acquirer shares equals your basis in the old target shares, and your holding period tacks — the time you held the target stock counts toward your holding period in the acquirer stock. You will owe capital gains tax only when you eventually sell the acquirer shares. If the deal includes any cash component ("mixed consideration"), only the cash portion is taxable to you — up to your total realized gain. Watch for elections: some mergers allow shareholders to elect an all-stock or all-cash allocation; the tax consequences of those elections differ significantly.

If you're a business owner selling your company and considering stock vs. cash consideration: A sale for acquirer stock in a § 368 reorganization defers your capital gains tax — potentially indefinitely if you hold the acquirer stock until death and your heirs receive a stepped-up basis. A sale for cash triggers immediate capital gains at rates up to 23.8% (federal) plus state taxes. The trade-off is concentration risk: you're now holding a large position in the acquirer rather than diversified assets. Sellers often negotiate "collar" structures (price adjustments based on the acquirer's stock price) and registration rights (allowing them to sell the acquirer shares on the public market). If you have a low basis in your company stock — typical for founders — the tax deferral value of a stock deal can be enormous relative to the risk of acquirer stock concentration.

If you work in corporate finance or M&A and are structuring a transaction: The choice of reorganization type drives the entire deal structure. Type A (merger) is the default for flexibility — it accommodates mixed consideration and can be done as a triangle merger to insulate the acquirer parent from target liabilities. Type B (stock-for-stock) is available only if you can fund the entire acquisition with acquirer voting stock, but it preserves the target as a subsidiary (useful for regulated entities where asset transfers trigger license revocations). Type C (stock-for-assets) lets you acquire selected assets without taking on unwanted liabilities, but requires a full target liquidation afterward. Tax counsel must be engaged early — the continuity-of-interest and continuity-of-business-enterprise doctrines apply from the signing date, meaning pre-closing trading activity by target shareholders can retroactively disqualify COI.

State Variations

Most states follow federal reorganization treatment for state corporate income tax purposes — if the reorganization qualifies under § 368 federally, no state corporate income tax is triggered on the exchange. However, state-level transfer taxes are a distinct issue: real estate transfer taxes in states like New York, Pennsylvania, and Maryland are triggered by asset transfers — a Type A or Type C reorganization that includes real property can create significant state transfer tax liabilities even if the federal transaction is tax-free. Delaware, as the most common state of incorporation, imposes no state corporate income tax on out-of-state income and has no real estate transfer tax triggered by most merger structures. California conforms to federal reorganization rules for corporation tax purposes but applies its own rules for California-sourced income allocation post-merger.

Implementing Regulations

• 26 CFR § 1.368-1 — Purpose and scope of exception of reorganization exchanges (the overarching continuity doctrines — COI, COBE, business purpose; the step-transaction doctrine)
• 26 CFR § 1.368-2 — Definition of terms (definitions of each reorganization type; triangular merger rules; "substantially all" for Type C; voting stock requirement for Type B)
• 26 CFR § 1.354-1 — Exchanges of stock and securities in certain reorganizations (shareholder non-recognition mechanics; boot allocation rules)
• 26 CFR § 1.356-1 — Receipt of additional consideration in certain reorganizations (the dividend-within-gain rule; how boot is characterized)
• 26 CFR § 1.368-3 — Records to be kept and information to be filed (reporting requirements for corporate parties)

Pending Legislation

• Continuity of interest regulatory changes: The IRS has periodically updated the COI regulations to address pre-signing stock trading and signing-date valuation. The current regulations (measuring COI at signing rather than closing) are relatively favorable to deal certainty, but further updates are possible.
• Type A triangle merger abuse: Congressional and Treasury concerns about the use of disregarded entities and hybrid structures in § 368(a)(2) triangle mergers to achieve reorganization treatment while avoiding acquired liabilities — ongoing regulatory activity to close gaps.

Recent Developments

• COI measured at signing, not closing: IRS regulations finalized in the 2000s (and updated since) provide that the continuity-of-interest test is measured on the signing date using the signing-date stock price, not the closing-date price. This means deal certainty is achievable even if the acquirer's stock price drops significantly between signing and closing — a critical protection for both parties in volatile markets.
• Cross-border reorganizations — TCJA impact: The Tax Cuts and Jobs Act of 2017 significantly changed the tax landscape for inbound and outbound corporate reorganizations involving foreign corporations. § 367 remains the primary statute governing cross-border reorganizations, imposing gain recognition on U.S. shareholders in many outbound § 368 reorganizations absent specific exceptions. International M&A teams must layer § 367 analysis on top of § 368 in any deal with a non-U.S. party.
• SPACs and § 368: The SPAC (Special Purpose Acquisition Company) boom raised novel questions about whether de-SPAC transactions could qualify as § 368 reorganizations. Most de-SPAC structures involve significant cash redemptions by SPAC shareholders, making COI satisfaction difficult. The IRS and Treasury issued guidance confirming that most de-SPAC structures do not qualify as § 368 reorganizations and are treated as taxable asset acquisitions.
