A Type C reorganization is a tax-deferred acquisition in which one corporation buys substantially all of another corporation’s assets using its own voting stock, after which the target corporation liquidates and distributes that stock to its shareholders. It is defined in Section 368(a)(1)(C) of the Internal Revenue Code, and when the transaction qualifies, neither the target, the buyer, nor the target’s shareholders recognize federal income tax gain on the exchange. The rules are rigid, though, and small structuring choices on consideration or liabilities can collapse the whole treatment.
What It Takes to Qualify
Payment Must Be in Voting Stock
The buyer has to pay for the target’s assets with its own voting stock. The statute uses the word “solely,” and it is taken seriously. Cash, notes, nonvoting preferred shares, and other non-stock property are generally not permitted as consideration. The voting stock can come from the acquiring corporation itself or, in a triangular deal, from its parent.1Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations
One carve-out keeps the rule workable: when the buyer assumes the target’s existing liabilities, those assumed debts are not treated as non-stock consideration for purposes of the “solely for voting stock” test. Without this exception, almost no asset deal could qualify, because targets virtually always carry some debt.1Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations
Substantially All of the Assets
The buyer must acquire substantially all of the target’s assets. The Code does not fix a percentage, but the IRS applies advance-ruling guidelines of at least 90% of the fair market value of the net assets and at least 70% of the fair market value of the gross assets. Courts have sometimes used a looser facts-and-circumstances approach that asks whether the buyer picked up the operating business, but most planners design around the IRS thresholds to avoid an audit fight.
Pre-closing moves by the target can break this test. Spinning off a division, distributing property to shareholders, or holding back large amounts of cash shrinks the asset pool being transferred and can push the ratios below the line. Managing what the target keeps versus what it transfers is usually the first conversation in structuring a C.
The 80% Rule and the Liability Trap
A narrow exception lets some non-stock consideration into the deal. If the buyer acquires at least 80% of the fair market value of the target’s assets solely for voting stock, the remaining 20% can be paid with cash or other property.1Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations
Here the liability-assumption exception circles back. For purposes of the 80% test only, every dollar of assumed liabilities counts as cash paid for the assets. This is the single most dangerous interaction in the C reorganization rules and routinely forces structural changes.1Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations
A simple example shows the squeeze. Say the target has $100 million in assets and $15 million in debt. The 20% boot cushion is $20 million. The assumed $15 million eats most of it, leaving only $5 million of room for actual cash. If the debt were $22 million instead, the liabilities alone would blow through the 20% cap, and the buyer could not pay any cash without disqualifying the deal. Highly leveraged targets effectively eliminate the boot relaxation rule, which means the buyer must pay 100% in voting stock and rely on the general liability-assumption carve-out.
The Target Must Liquidate
After the asset transfer, the target corporation must distribute everything it received from the buyer, plus any remaining property, to its own shareholders under the plan of reorganization. The statute is explicit: without this distribution, the deal fails to qualify.2Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations – Section: Special Rules Relating to Paragraph (1)
Payments to creditors during that liquidation count as distributions made under the plan, and a limited exception lets the target retain a small amount of cash for wind-down expenses. What the target cannot do is keep operating as a standalone company after the deal. That is what makes a C function like a merger from the shareholders’ point of view: they walk in holding target stock and walk out holding acquiring-corporation stock, with no entity surviving in between.
The Three Doctrinal Requirements
Meeting the statutory tests is necessary but not enough. Treasury Regulation 1.368-1 imposes three additional requirements, and failing any one of them disqualifies the entire transaction.
Business Purpose
The reorganization must serve a genuine corporate business purpose beyond tax savings. A deal built purely to generate a tax benefit, with no operational or strategic rationale, is not a reorganization. The doctrine traces back to Gregory v. Helvering and is codified in regulations that place a transaction with “no business or corporate purpose” outside the reorganization rules entirely.3eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Continuity of Business Enterprise
The acquiring corporation must either continue the target’s historic business or use a significant portion of the target’s historic business assets in some business. A buyer that acquires a manufacturer and immediately shutters the plant to sell off the equipment would have trouble meeting this test.3eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Continuity of Interest
A substantial portion of the target shareholders’ equity interest must be preserved through ownership in the acquiring corporation. In a C, the “solely for voting stock” requirement largely handles this on its own, because the shareholders end up holding acquiring-corporation stock after the liquidation. It matters more when boot enters the picture. For advance ruling purposes, the IRS has historically looked for at least 40% of the total consideration to be equity.
Tax Consequences for the Target
In a qualifying C reorganization, the target recognizes no gain or loss on transferring its assets to the buyer for voting stock. This nonrecognition comes from Section 361. The target also recognizes no gain or loss when it distributes the buyer’s stock to its own shareholders during the mandatory liquidation, as long as what it distributes is “qualified property,” which is primarily the stock received in the exchange.
If the target distributes appreciated property other than the buyer’s stock during the liquidation, gain recognition can apply on that distribution. This rarely comes up in a well-planned C, because the target typically transfers all operating assets to the buyer and distributes only the buyer’s stock. It is a trap in deals where the target has held something back.
Tax Consequences for the Buyer
The buyer recognizes no gain or loss when it issues its own voting stock in exchange for the target’s assets. Section 1032 provides that a corporation never recognizes gain or loss on transactions in its own stock.
What the buyer does inherit is the target’s historical tax basis in each asset. Under Section 362(b), the buyer takes carryover basis rather than a step-up to fair market value, increased by any gain the target recognized on the transfer (usually zero in a qualifying C).4Office of the Law Revision Counsel. 26 USC 362 – Basis to Corporations
Carryover basis has real consequences. If the target bought equipment for $2 million and depreciated it to $500,000, the buyer’s basis is $500,000. A later sale at fair market value triggers all the deferred gain. The tax savings here are a deferral, not an exclusion.
Carryover of Tax Attributes
Beyond basis, the buyer inherits the target’s broader tax attributes under Section 381. These include net operating loss carryovers, earnings and profits, accounting methods, and various credit carryforwards. The buyer takes these as of the close of the day of the asset transfer.5Office of the Law Revision Counsel. 26 USC 381 – Carryovers in Certain Corporate Acquisitions
NOL use is restricted in the year of the transfer. The buyer can only apply the target’s NOL carryovers against a proportional slice of its taxable income based on the days remaining in its tax year after the transfer date. If the deal closes on October 1 and the buyer’s year ends December 31, only about a quarter of the buyer’s annual taxable income is available to absorb those losses that first year.5Office of the Law Revision Counsel. 26 USC 381 – Carryovers in Certain Corporate Acquisitions
Section 382 Limitation
The more significant restriction on inherited NOLs comes from Section 382, which applies when there is a significant ownership change. A C reorganization typically produces one, because the target’s former shareholders now hold acquiring-corporation stock.
When it applies, Section 382 caps the annual amount of pre-change losses that can offset the combined company’s taxable income. The cap equals the fair market value of the old loss corporation immediately before the ownership change, multiplied by the IRS-published long-term tax-exempt rate for the month of the change.6Office of the Law Revision Counsel. 26 USC 382 – Limitation on Net Operating Loss Carryforwards and Certain Built-In Losses Following Ownership Change
If the target was worth $50 million before the deal and the applicable rate is 4%, the annual cap on using the target’s pre-change NOLs is $2 million. A target with $30 million in accumulated losses would need 15 years to absorb them, assuming the buyer earns enough each year to use them. Capital contributions made within two years before the ownership change are excluded from the valuation, which keeps companies from inflating the cap by stuffing equity into the target shortly before closing.
Tax Consequences for Shareholders
Target shareholders who receive only the buyer’s voting stock in the liquidating distribution recognize no gain or loss. Their basis in the new stock equals their old basis in the target stock, adjusted for any boot received or gain recognized.7Office of the Law Revision Counsel. 26 USC 358 – Basis to Distributees
When shareholders receive boot alongside the stock, they recognize gain up to the value of the boot. They recognize gain only, never loss. A shareholder with a $10,000 basis in target stock who receives $80,000 in acquiring-corporation stock plus $5,000 in cash recognizes $5,000 of gain, even though the total value received exceeds basis by far more. A shareholder with a built-in loss gets no current deduction from receiving boot.8Office of the Law Revision Counsel. 26 USC 356 – Receipt of Additional Consideration
The character of that gain is normally capital. If the cash has the “effect of a distribution of earnings and profits,” though, the gain can be recharacterized as a dividend to the extent of the shareholder’s ratable share of the target’s accumulated earnings and profits. The analysis asks what would have happened if the shareholder had received only stock and then redeemed part of it for cash; if that hypothetical redemption would have been treated as a dividend, so is the boot.8Office of the Law Revision Counsel. 26 USC 356 – Receipt of Additional Consideration
Reporting Obligations
Tax-free treatment does not mean paperwork-free. Every corporate party to the reorganization and every “significant holder” must attach a statement to the tax return for the year of the deal, describing the reorganization and the basis of the transferred property. A significant holder is generally any shareholder owning at least 5% of a publicly traded corporation or 1% of a privately held corporation, by vote or value.9Internal Revenue Service. Notice 2009-4 – Determination of Basis in Property Acquired in Transferred Basis Transaction
The acquiring corporation also has to file Form 8937, which reports organizational actions affecting securities basis. It is due within 45 days after the reorganization or by January 15 of the following year, whichever is earlier. The corporation can satisfy the requirement by posting a completed, signed Form 8937 on its primary public website in lieu of filing, as long as the form stays accessible for 10 years. The issuer must also provide a statement to all holders or their nominees by January 15 of the year after the reorganization.10Internal Revenue Service. Instructions for Form 8937 – Report of Organizational Actions Affecting Basis of Securities
Missing these filings does not automatically disqualify the reorganization, but it exposes the parties to penalties and complicates any later IRS examination. Shareholders who are not significant holders still need to report the exchange and track their substituted basis in the new stock.
When a Type C Makes Sense Instead of a Statutory Merger
A Type A reorganization, which is a statutory merger under state law, offers more flexibility on consideration. The buyer can mix cash, debt, and other property as long as equity makes up enough of the total deal. So why pick the more restrictive C structure?
The main reason is control over liabilities. In a statutory merger, the buyer inherits all of the target’s obligations by operation of state law. In a C, the buyer acquires specific assets and chooses which liabilities to assume. If the target has unknown environmental exposure, pending litigation, or other contingent liabilities, a C lets the buyer leave those behind. The target’s creditors keep their claims against the target or its liquidating estate; those claims do not automatically follow the assets.
A C can also help when state merger statutes create procedural hurdles or require approvals the parties would rather avoid. Because the deal is structured as an asset purchase rather than a statutory merger, certain state-law requirements may not apply. The tradeoff is the rigid consideration rules, the liability-assumption trap inside the 80% test, and the mandatory liquidation at the end.
