Type C Reorganization Explained: Assets-for-Stock in 2026 (Tax-Free)

Key Takeaways

• Type C under IRC 368(a)(1)(C) is an assets-for-stock acquisition where the target liquidates and distributes acquirer stock to shareholders
• Substantially-all assets test requires at least 70 percent of fair market value of net assets and 90 percent of fair market value of gross operating assets
• Solely-for-voting-stock requirement is strict, but the boot relaxation rule allows up to 20 percent in cash or other property if other conditions met
• Type C requires shareholder approval and target liquidation; not a simple acquisition
• Best used when Type B fails (target has too many liabilities), Type A is impractical (no statutory merger statute), or assets need selective treatment
• Reg 1.368-1(d) and 1.368-2(d) provide the implementing regulations; Form 8937 reporting required post-close

What is a Type C reorganization?

A Type C reorganization, defined in Internal Revenue Code section 368(a)(1)(C), is one of three primary statutory tax-free reorganization formats. The basic structure: the target corporation transfers substantially all of its assets to the acquiring corporation in exchange for the acquiring corporation’s voting stock, then the target liquidates and distributes that stock to its shareholders.

The transaction has three moving parts that happen in sequence:

Step 1: Asset transfer. The target corporation transfers substantially all of its operating assets to the acquirer. Liabilities may or may not be assumed; the assumption of liabilities is treated as money received for purposes of the boot calculation.

Step 2: Stock issuance. The acquirer issues its voting stock to the target corporation as the consideration for the transferred assets.

Step 3: Target liquidation. The target corporation liquidates and distributes the acquirer’s voting stock (along with any remaining assets) to its shareholders.

If the transaction meets all statutory and judicial requirements, neither the target corporation nor its shareholders recognize gain on the transaction. The target shareholders take a substituted basis in the acquirer stock equal to their basis in the target stock.

Type C sits between Type A (statutory merger) and Type B (stock-for-stock acquisition) in the spectrum of tax-free reorganizations. It is used in roughly 8 to 12 percent of qualifying tax-free reorganizations according to law firm transaction data from Wachtell, Lipton, Rosen & Katz and Cravath, Swaine & Moore.

For the broader landscape of reorganization structures, see type a reorganization explained for statutory mergers and type b reorganization explained for stock-for-stock acquisitions.

Why Type C is structurally different from Type A and Type B

Type A is a statutory merger under state law; the target ceases to exist by operation of law. Type B is a stock acquisition; the target continues as a subsidiary. Type C is an asset acquisition followed by target liquidation; the target is wound up by corporate action rather than disappearing into a merger. Each structure produces the same net result (target shareholders own acquirer stock) but through different mechanics with different requirements and tax consequences.

Common Type C transaction examples

Type C reorganizations are common in industries where: (1) statutory merger statutes are limited or impractical (some specialty corporate forms), (2) the target has significant contingent liabilities the acquirer wants to leave behind, or (3) the parties want to selectively transfer assets while liquidating the target’s corporate shell. Many spin-off and split-up transactions also use Type C structures as part of larger Section 355 transactions.

The substantially-all assets test

The defining requirement of a Type C reorganization is the substantially-all assets test. This is the threshold test that distinguishes a tax-free Type C from a taxable asset sale.

The statute itself does not define ‘substantially all.’ The implementing regulations and IRS rulings provide the operational standard:

Revenue Procedure 77-37 (IRS ruling guidelines): for advance ruling purposes, substantially-all is met when:

• At least 70 percent of the fair market value of net assets, AND
• At least 90 percent of the fair market value of gross operating assets

are transferred. Both tests must be met; failing either test fails the substantially-all requirement.

Net assets means total assets minus liabilities. Gross operating assets means assets used in the active conduct of the business, excluding investment assets and assets distributed to shareholders prior to the transaction.

The distinction matters: a target that distributes excess cash to shareholders before the transaction reduces its net assets, which can fail the 70 percent net assets test. The transaction planning must time pre-closing distributions carefully.

In private letter rulings, the IRS has approved transactions where slightly less than the published thresholds were met when other factors (continuity of business, continuity of interest) were strong. PLRs are not precedent for other taxpayers, but they provide directional guidance.

In ruling-free transactions (most commercial deals), the parties rely on the published thresholds and case law including Atlas Tool Co. v. Commissioner (1956) and Smothers v. United States (1981). Tax counsel typically structures with significant margin above the thresholds to avoid challenge.

Pre-transaction distributions and the substantially-all test

Pre-transaction distributions of cash, investment securities, or non-operating assets can disqualify the transaction if they cause the substantially-all test to fail. The conservative approach: any pre-transaction distribution should be planned well in advance with tax counsel review. Anti-abuse doctrines (step transaction, substance over form) can cause the IRS to recharacterize a planned series of transactions.

What happens when the test fails

If the substantially-all test fails, the transaction is recharacterized as a taxable asset sale. The target recognizes gain on the difference between fair market value and tax basis on each asset. The shareholders recognize gain on the distribution of acquirer stock as if they received cash equal to the fair market value of the stock. This is a complete tax catastrophe that motivates the careful structuring of every Type C transaction.

The solely-for-voting-stock requirement and boot relaxation

Type C reorganizations must satisfy the solely-for-voting-stock requirement of IRC 368(a)(1)(C): the assets must be acquired solely in exchange for voting stock of the acquirer. The strict reading would prohibit any cash or other property in the transaction.

In practice, IRC 368(a)(2)(B), the boot relaxation rule, modifies the strict reading. Under the boot relaxation rule:

The acquirer may pay up to 20 percent of the fair market value of all consideration in cash or other property (boot), provided that:

1. At least 80 percent of the fair market value of all the target’s property is acquired solely for voting stock, AND 2. The amount paid for the property other than in voting stock is treated as boot received by the shareholders.

For purposes of the boot calculation, assumption of liabilities is generally treated as money paid for the assets. This is a critical structuring point: if liabilities equal 25 percent of fair market value of assets, the boot relaxation rule is already breached before any cash changes hands. The transaction fails Type C qualification.

The interaction between liability assumption and the boot rule is the most common technical pitfall in Type C planning. Practitioners often structure the transaction to leave liabilities behind (assumed by a remaining shell) or to satisfy them with cash before closing.

When boot is paid (within the 20 percent limit), the target shareholders recognize gain to the extent of the boot received, but only up to the amount of their realized gain. The shareholders’ basis in the acquirer stock is adjusted to reflect the boot received.

The liability assumption trap

A target with 500,000 of liabilities and 1.5 million of asset fair market value: the liabilities are 33 percent of asset value, exceeding the 20 percent boot relaxation limit. Even with no cash paid, the transaction fails Type C qualification. The fix is to leave the liabilities behind in the target shell with the seller assuming them, structure as Type A or D, or have the target pay down liabilities before closing using shareholder capital contributions.

Boot timing and characterization

Boot can be paid either at closing or under contingent payment arrangements. Contingent boot (escrows, earnouts) is treated under the installment method if it qualifies. Most Type C transactions avoid earnouts because they complicate the boot rule analysis. A simpler structure uses fixed consideration with minimal boot.

Continuity doctrines and the business purpose test

Beyond the statutory tests, Type C reorganizations must satisfy three judicial doctrines that apply to all tax-free reorganizations.

Continuity of Interest (COI) doctrine. The target shareholders must continue a proprietary interest in the acquirer through their ownership of acquirer stock. Treas. Reg. 1.368-1(e) implements the doctrine. The minimum interest is roughly 40 percent of consideration in qualifying stock (per Rev. Proc. 77-37; the 2005 regulations confirm this approximate threshold). Below 40 percent, the IRS will challenge COI; above 40 percent, COI is generally satisfied.

Continuity of Business Enterprise (COBE) doctrine. The acquirer must continue the target’s historic business or use a significant portion of the target’s historic business assets. Treas. Reg. 1.368-1(d) implements the doctrine. The acquirer cannot simply liquidate or significantly redirect the acquired assets immediately after the transaction.

Business Purpose doctrine. The transaction must serve a legitimate business purpose beyond tax avoidance. While the bar is low (any plausible business reason satisfies the doctrine), tax-motivated transactions without operational substance can be recharacterized under economic substance doctrines, including IRC section 7701(o).

For Type C transactions, COI and COBE are typically not problematic because the target shareholders receive acquirer voting stock and the acquirer continues operating the acquired assets. The business purpose doctrine is generally satisfied by the commercial rationale for the acquisition.

The step transaction doctrine sometimes applies to Type C transactions, particularly when a series of related transactions occur. If two transactions are interdependent steps in a larger plan, the IRS may combine them and apply the tax rules as if they were a single transaction. Tax counsel structures the transaction sequence carefully to avoid step transaction characterization.

For a broader treatment of reorganization doctrines, see tax-free reorganizations a roadmap for smooth business sales.

Historic business or historic asset test

COBE requires the acquirer to continue either the target’s historic business OR use a significant portion of the historic business assets. The ‘or’ is important: an acquirer that fundamentally redirects the target’s business but uses the same assets can satisfy COBE; an acquirer that continues the same business in a new asset base can also satisfy COBE. The regulation provides examples and safe harbors.

Documentation of business purpose

Document the business purpose of the transaction in board minutes, transaction memos, and the disclosure schedules. The documentation should articulate the operational rationale (strategic fit, cost synergies, market positioning) beyond the tax treatment. Form 8937 reporting after close requires identifying the business purpose.

Mechanics: how to actually execute a Type C reorganization

The mechanical execution of a Type C reorganization has more steps than a Type A merger or Type B stock acquisition. The execution must be carefully sequenced to satisfy all requirements.

Pre-closing steps:

Obtain target board and shareholder approval. Most states require shareholder approval for the transfer of substantially all assets. The vote threshold varies by state (typically majority or two-thirds).

Negotiate and execute the definitive asset purchase agreement, which includes representations and warranties, indemnification, and conditions to closing.

Obtain regulatory approvals (HSR Act, FCC if applicable, state regulatory bodies if applicable).

Obtain third-party consents (key customer contracts, lease agreements, license agreements that have assignment restrictions).

At closing:

The target conveys all transferred assets to the acquirer via bills of sale, deeds, assignments, and similar transfer documents.

The acquirer assumes specified liabilities by an assumption agreement.

The acquirer issues its voting stock to the target as consideration. The stock certificates are issued or book-entry registered in the target’s name.

The acquirer pays any boot (cash or other property) consideration within the 20 percent limit, if applicable.

Post-closing within 30 days:

The target board adopts a plan of liquidation. Most states require board and shareholder approval of the plan of liquidation.

The target distributes the acquirer’s voting stock to its shareholders in liquidation. Shareholders surrender their target stock certificates and receive acquirer stock certificates.

The target files IRS Form 8937 to report the substituted basis adjustments to shareholders.

The target files IRS Form 966 (corporate dissolution or liquidation) within 30 days of adopting the plan of liquidation.

The target files final corporate tax returns and dissolves under state law.

The entire sequence from closing to final target dissolution typically takes 60 to 180 days depending on state procedures and remaining wind-up matters.

Why the target liquidates

The liquidation requirement is critical for Type C qualification. Without the liquidation, the target would hold the acquirer’s stock as an investment, which is not the Type C pattern. The liquidation passes the acquirer stock through to the target shareholders, completing the substituted basis pattern intended by the statute.

What if the target cannot liquidate quickly

Some targets have contingent liabilities (pending litigation, environmental claims) that prevent quick liquidation. The target can remain in existence as a wind-up entity holding cash reserves for the contingent liabilities while transferring substantially all operating assets. Tax counsel structures the wind-up entity to avoid challenging the substantially-all test.

When to choose Type C over Type A or Type B

The choice between Type A, Type B, and Type C depends on transaction-specific factors. Each structure has comparative advantages.

Choose Type C when:

Liability concerns. The acquirer wants to leave certain liabilities behind. Type C allows selective liability assumption (subject to the boot rule), while Type A (statutory merger) typically transfers all liabilities by operation of law.

State merger statute limitations. Some specialty entities (certain professional corporations, regulated entities) cannot effect a statutory merger. Type C provides a path when Type A is unavailable.

Multi-step transactions. Type C is often used as one step in a larger restructuring, particularly Section 355 spin-offs and split-ups, where assets need to be transferred to a new subsidiary in a controlled sequence.

Target has minority shareholders with appraisal rights. Some states give dissenting shareholders broader appraisal rights in mergers than in asset transactions. Type C can sometimes proceed when Type A would face appraisal demands.

Choose Type A when:

Simplicity. Statutory mergers are mechanically simpler. State merger statute handles the asset transfer, liability assumption, and target dissolution in one step.

Liability assumption is acceptable. If the acquirer is comfortable assuming all target liabilities, Type A’s automatic liability transfer is operationally simpler than the asset-by-asset transfer required in Type C.

Choose Type B when:

Target continues as subsidiary. The acquirer wants to keep the target as a subsidiary (preserving licenses, contracts, customer relationships tied to the target entity).

No asset transfer required. Type B has no asset transfer; it is purely a stock acquisition. Operationally simpler than Type C asset transfers and target liquidation.

The choice is rarely about tax efficiency alone; all three structures produce the same tax-free result when properly executed. The choice is about transaction mechanics, liability management, and post-close corporate structure.

Triangular variants

IRC 368(a)(2)(C) allows a forward triangular Type C, where the acquirer’s subsidiary acquires the target assets using the acquirer’s stock. The subsidiary becomes the operating entity. This is rarely used because Type A reverse triangular mergers handle the same fact pattern with simpler mechanics. When deployed, the triangular Type C must satisfy additional requirements including a control test (parent must own 80 percent of subsidiary).

Common transaction errors that disqualify Type C

Three errors regularly disqualify Type C transactions: (1) liabilities assumed plus cash paid exceeds 20 percent of total consideration, breaking the boot rule; (2) pre-closing dividends or distributions reduce net assets below the substantially-all threshold; (3) target fails to liquidate or liquidates so slowly that the IRS considers the transaction step incomplete. Each is preventable with careful planning.

Tax consequences for the target, acquirer, and shareholders

A properly executed Type C reorganization produces specific tax results at three levels.

Target corporation tax treatment:

The target recognizes no gain or loss on the transfer of assets to the acquirer in exchange for voting stock (IRC 361(a)). If boot is received in addition to stock, gain is recognized to the extent of boot, but not loss (IRC 361(b)).

Upon distribution of the acquirer stock to target shareholders in liquidation, the target recognizes no gain or loss (IRC 361(c)).

The target’s tax attributes (net operating losses, credits, accounting methods) generally carry over to the acquirer under IRC 381, subject to the limitations of IRC 382 if there is a substantial ownership change.

Acquirer corporation tax treatment:

The acquirer takes a carryover basis in the acquired assets (IRC 362(b)). The acquirer’s basis in each asset equals the target’s basis in that asset, plus any gain recognized by the target on that asset.

If boot is paid, the acquirer’s basis in the assets is adjusted to reflect the boot.

The acquirer assumes the target’s tax attributes under IRC 381, subject to IRC 382 limitations.

Shareholder tax treatment:

Target shareholders recognize no gain on the exchange of target stock for acquirer stock (IRC 354(a)). If boot is received, gain is recognized to the extent of boot, but only up to realized gain (IRC 356(a)).

Shareholders take a substituted basis in the acquirer stock equal to their basis in the target stock, decreased by any boot received and increased by any gain recognized (IRC 358(a)).

The shareholders’ holding period in the acquirer stock includes the holding period in the target stock (IRC 1223).

Reporting requirements:

Form 8937 (Report of Organizational Actions Affecting Basis of Securities) must be filed by the target within 45 days of the transaction, or posted to the target’s public website, providing shareholders with the information needed to compute substituted basis.

Form 966 (Corporate Dissolution or Liquidation) must be filed within 30 days of adopting the plan of liquidation.

The acquirer attaches a statement to its tax return identifying the reorganization, the parties, and the IRC section under which the reorganization qualifies (Treas. Reg. 1.368-3).

Section 382 ownership change limitations

If the Type C transaction causes a more than 50 percentage point ownership change in the target stock under IRC 382, the acquirer’s use of carried-over net operating losses is limited to a defined annual amount (the section 382 limitation, calculated as long-term tax-exempt rate times target equity value). Most acquisitions trigger 382 limitations; tax counsel models the limitation as part of acquisition pricing.

Foreign target considerations

If the target is a foreign corporation, additional rules apply under IRC 367. The transfer of assets to a US acquirer can trigger gain recognition under section 367(a) unless an exception applies. The structure must consider both domestic reorganization rules and the section 367 outbound transfer rules.

When Type C does not work and how to fix it

Several common scenarios prevent Type C qualification or make it impractical. Each has a fix.

Scenario 1: Liabilities exceed 20 percent of fair market value of assets.

Problem: The boot relaxation rule breaks before any cash is paid.

Fix options:

• Leave the liabilities behind in a wind-up shell (target retains the liabilities, transfers only the assets net of associated liabilities). Tax counsel structures the wind-up entity carefully.
• Pay down liabilities before closing using shareholder capital contributions.
• Restructure as Type A (statutory merger), which has no boot rule.
• Restructure as Type D (acquisitive Type D under IRC 368(a)(1)(D)), which has different mechanics.

Scenario 2: Substantially-all test fails because of investment assets or excess cash.

Problem: The target holds significant non-operating assets (excess cash, investment securities, real estate not used in operations) that reduce the operating asset percentage.

Fix options:

• Distribute non-operating assets to shareholders before the reorganization (carefully sequenced to avoid step transaction issues).
• Structure as Type A with the non-operating assets handled in the merger.
• Structure as a Section 355 spin-off of non-operating assets followed by a Type C of the operating business.

Scenario 3: Shareholders object to substituted basis.

Problem: Some shareholders want a step-up in basis (cash sale treatment) rather than carryover basis.

Fix options:

• Allow boot to those shareholders within the 20 percent limit (they recognize gain to the extent of boot, partial basis step-up).
• Restructure as a hybrid: tax-free portion for shareholders who want continuity, cash-out for shareholders who want immediate liquidity. This requires careful structuring to avoid disqualifying the transaction.
• Structure as a taxable acquisition with full step-up; accept the entity-level and shareholder-level tax cost.

Scenario 4: State approval requirements differ between asset transfer and merger.

Problem: Asset transfers in some states require unanimous shareholder consent or trigger broader regulatory review than mergers.

Fix options:

• Restructure as Type A (statutory merger) if state merger requirements are easier.
• Negotiate with dissenting shareholders before the transaction.
• Use a triangular Type C variant to manage state-level requirements.

Each fix involves trade-offs in tax treatment, transaction complexity, and timing. Tax counsel evaluates the comparative cost of each option against the operational and commercial requirements of the transaction.

Type D as a Type C alternative

IRC 368(a)(1)(D) acquisitive D reorganizations are similar to Type C but with different qualification requirements. Type D requires substantially-all transfer plus a control requirement (the target shareholders must control the acquirer after the transaction, defined as 80 percent ownership). When Type C fails because of the boot rule but the parties want to maintain the asset-for-stock pattern, Type D can sometimes substitute.

Drop-down to subsidiary planning

Some Type C transactions are followed by a drop-down of the acquired assets to a wholly-owned subsidiary of the acquirer. The drop-down is permissible under IRC 368(a)(2)(C) and does not disqualify the Type C. This is often done for liability segregation or corporate organizational purposes after the tax-free reorganization is complete.

Frequently Asked Questions

What is a Type C reorganization?

A Type C reorganization under IRC 368(a)(1)(C) is a tax-free reorganization where the target corporation transfers substantially all of its assets to the acquiring corporation in exchange for the acquirer’s voting stock, then the target liquidates and distributes that stock to its shareholders. If properly executed, neither the target nor its shareholders recognize gain.

What is the substantially-all assets test in Type C?

Per Rev. Proc. 77-37, the substantially-all test for advance ruling purposes requires the transfer of at least 70 percent of the fair market value of net assets and at least 90 percent of the fair market value of gross operating assets. Both prongs must be satisfied.

Can the acquirer pay any cash in a Type C reorganization?

Yes, under the boot relaxation rule of IRC 368(a)(2)(B), the acquirer may pay up to 20 percent of total consideration in cash or other property, provided at least 80 percent of the fair market value of target property is acquired solely for voting stock. Assumed liabilities count as boot for this calculation.

How is a Type C reorganization different from a Type A merger?

Type A is a statutory merger; the target ceases to exist by operation of state law and all liabilities transfer automatically to the acquirer. Type C is an asset acquisition where the target liquidates separately; liabilities can be selectively assumed subject to the boot rule.

How is a Type C different from a Type B stock-for-stock?

Type B acquires the target stock and the target continues as a subsidiary. Type C acquires the target assets and the target liquidates. Type C is more complex mechanically but allows the acquirer to leave certain liabilities behind. Type B has no boot allowance; Type C has a 20 percent boot allowance.

Does the target need shareholder approval for a Type C?

Yes. Most state corporate codes require shareholder approval for the sale of substantially all assets. The required vote varies by state (typically majority or two-thirds). Shareholder approval is also required for the post-closing liquidation.

What is the boot rule trap in Type C reorganizations?

Assumed liabilities are treated as money paid for the assets in the boot calculation. A target with liabilities exceeding 20 percent of asset fair market value automatically fails the boot relaxation rule even if no cash is paid. The fix is to leave liabilities behind in a wind-up entity, pay them down before closing, or restructure as Type A.

How do target shareholders compute basis in the acquirer stock?

Under IRC 358, shareholders take a substituted basis equal to their basis in the target stock, decreased by any boot received and increased by any gain recognized. The holding period in the acquirer stock includes the holding period in the target stock under IRC 1223.

Are net operating losses transferred in a Type C?

Yes, under IRC 381 the target’s tax attributes including NOLs, credits, and accounting methods carry over to the acquirer. However, IRC 382 limitation applies if there is a more than 50 percentage point ownership change in the target, limiting the acquirer’s use of carried-over NOLs to an annual amount.

What forms must be filed for a Type C reorganization?

Form 8937 (Report of Organizational Actions Affecting Basis of Securities) must be filed by the target within 45 days. Form 966 (Corporate Dissolution or Liquidation) must be filed within 30 days of adopting the plan of liquidation. The acquirer attaches a Treas. Reg. 1.368-3 statement to its tax return identifying the reorganization.
