A Type B reorganization is a stock-for-stock acquisition, defined in IRC Section 368(a)(1)(B), that lets one corporation acquire control of another without immediate federal income tax for the companies or the selling shareholders. To qualify, the acquirer must pay solely with its own voting stock (or the voting stock of its parent) and must hold at least 80 percent of the target immediately after the exchange.1Office of the Law Revision Counsel. 26 U.S. Code 368 – Definitions Relating to Corporate Reorganizations Miss either test and the entire deal is taxable.
The Two Statutory Tests
Everything in a Type B turns on two rules working together.
Solely for Voting Stock
The acquiring corporation may offer target shareholders nothing except its own voting stock, or the voting stock of a parent that controls it. Voting stock is any share that carries a genuine right to vote for directors, and it can be common, preferred, or even contingent stock so long as the holder actually votes.
“Solely” is read literally. A small cash sweetener alongside the stock does not just create taxable boot for the shareholder who receives it; it disqualifies the whole reorganization, making every share exchanged in the deal a taxable event. That rigidity is the defining feature of a Type B and the point that most often separates a qualifying deal from a failed one.
80 Percent Control Immediately After
Control is defined in IRC Section 368(c), and it takes two simultaneous tests to satisfy:2Office of the Law Revision Counsel. 26 U.S. Code 368 – Definitions Relating to Corporate Reorganizations – Section: Control Defined
- Stock carrying at least 80 percent of the total combined voting power of all classes entitled to vote.
- At least 80 percent of the total number of shares of every other class of stock outstanding.
The acquirer doesn’t have to cross that line through the current exchange alone. Stock it already owns counts, and the statute expressly applies “whether or not such acquiring corporation had control immediately before the acquisition.”1Office of the Law Revision Counsel. 26 U.S. Code 368 – Definitions Relating to Corporate Reorganizations A corporation that already holds 50 percent can add another 31 percent in a voting-stock exchange and satisfy the test.
One consequence worth flagging: because the threshold is 80 percent, a Type B can leave minority holders in place. The target survives as a subsidiary, and shareholders who refuse the exchange keep their shares. That is different from a merger, and it is sometimes useful and sometimes a headache.
Where Type B Deals Go Wrong
The Fractional-Share Carve-Out
The IRS permits cash paid to round off fractional shares that fall out of the exchange ratio. The theory is that rounding cash is mechanical convenience, not bargained-for consideration. Push it past true rounding and the exception is gone.
Creeping Acquisitions and the Step Transaction Doctrine
Nothing prevents an acquirer from having bought some target stock for cash in an earlier, unrelated transaction and then launching a voting-stock exchange to cross the control line. The prior cash purchase is fine on its own facts. It becomes fatal if the IRS or a court treats it and the later exchange as steps in a single integrated plan, because then cash paid in the “first step” is really cash paid for target stock in the reorganization.
There is no bright-line waiting period. Distance in time and the absence of a prearranged plan help; recent cash purchases warrant careful documentation before an acquirer moves to a Type B.
Incidental Payments
Because any non-stock consideration destroys the entire deal, tax counsel scrutinizes everything moving between the parties, including items like the acquirer picking up target expenses. What looks incidental can be recharacterized as consideration for the stock.
Judicial Doctrines Layered on Top
Clearing the statute is necessary but not sufficient. Tax-free reorganizations exist because the transaction is treated as a change in form rather than a sale, and two judicial doctrines police that policy.
Continuity of Proprietary Interest
Treasury Regulation Section 1.368-1(e) requires that a substantial part of the target shareholders’ ownership stake be preserved through stock in the issuing corporation; interests exchanged for cash or other property don’t count toward continuity.3eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganizations In a Type B, the solely-for-voting-stock rule effectively guarantees continuity, since 100 percent of the consideration is stock. Related-party purchases or later recharacterizations can still create problems.
Continuity of Business Enterprise
Under Treasury Regulation Section 1.368-1(d), 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.3eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganizations If the target has more than one business line, continuing one significant line is enough. The rule blocks acquirers from liquidating the target immediately and calling the exchange a restructuring.
Tax Treatment When the Deal Qualifies
A qualifying Type B produces non-recognition of gain or loss for all three parties: the target, the acquirer, and the exchanging shareholders. That is the whole reason to structure the deal this way.
The Target
The target recognizes no gain or loss. Because the exchange runs between the acquirer and the target’s shareholders, the target company itself is untouched. Its assets, liabilities, and tax attributes carry forward, and it becomes a subsidiary of the acquirer.
The Acquirer
Under IRC Section 1032, a corporation never recognizes gain or loss on receiving property in exchange for its own stock, so the acquirer books no gain when it issues shares for target stock.4Office of the Law Revision Counsel. 26 U.S. Code 1032 – Exchange of Stock for Property Its basis in the target shares it receives is a carryover basis under IRC Section 362(b): the acquirer steps into the shoes of the former target shareholders and takes the same aggregate basis they had.5Office of the Law Revision Counsel. 26 U.S. Code 362 – Basis to Corporations
The Target Shareholders
Shareholders who exchange target stock solely for voting stock of the acquirer recognize no gain or loss under IRC Section 354.6Office of the Law Revision Counsel. 26 U.S. Code 354 – Exchanges of Stock and Securities in Certain Reorganizations Their basis in the new stock equals the basis they had in the target stock they surrendered, under IRC Section 358.7Office of the Law Revision Counsel. 26 U.S. Code 358 – Basis to Distributees Holding periods tack: time already held in the target counts toward long-term status in the new shares.
What Happens If the Deal Fails
A failed Type B is not partially tax-free. It is treated as a straightforward taxable stock purchase. Target shareholders recognize capital gain or loss measured against the fair market value of the acquirer stock they received. The acquirer takes a cost basis (the fair market value of the stock it issued), and the shareholders take fair market value basis in the new shares.
The all-or-nothing character matters. In a Type A or Type C reorganization, non-stock consideration creates boot that is taxable to the recipient without necessarily destroying the reorganization for everyone else. In a Type B, one bad payment taxes every shareholder who participated. That is why the consideration package gets combed through in advance.
How Type B Compares to Other Structures
The Type B is the only standard reorganization form in which the target survives as a separate subsidiary rather than being merged out of existence (Type A) or transferring its assets to the acquirer (Type C). Keeping the target entity intact preserves its contracts, licenses, and legal identity, which is valuable in industries where those items don’t transfer cleanly.
The cost is the solely-for-voting-stock rule. A reverse triangular merger under IRC Section 368(a)(2)(E) reaches a similar structural result, with the target surviving as a subsidiary, while allowing some non-stock consideration and eliminating minority holders. Many acquirers that first look at a Type B end up using a reverse triangular merger for that flexibility. A Type B still fits when the acquirer wants a pure stock swap, is comfortable with minority holders remaining, and values keeping the target entity untouched.
Filings and Reporting
Both the acquirer and the target must attach a statement to their federal income tax returns for the year of the reorganization, identifying the parties, the date, and the value and basis of the stock transferred, as required by Treasury Regulation Section 1.368-3(a).8eCFR. 26 CFR 1.368-3 – Records to Be Kept and Information to Be Filed With Returns If the target is later liquidated into the acquirer as part of the plan, it must file IRS Form 966 within 30 days after adopting the plan of liquidation.9eCFR. 26 CFR 1.6043-1 – Return Regarding Corporate Dissolution or Liquidation
Significant Holder Reporting
Certain shareholders have their own filing obligation. Thresholds depend on whether the target’s stock was publicly traded:10GovInfo. 26 CFR 1.368-3 – Records to Be Kept and Information to Be Filed With Returns
- Publicly traded target stock: a shareholder who owned at least 5 percent by vote or value immediately before the exchange.
- Non-publicly traded target stock: a shareholder who owned at least 1 percent by vote or value immediately before the exchange.
- Securities holders: a holder of target securities with a basis of $1,000,000 or more immediately before the exchange.
A significant holder attaches a statement to the return for the year of the exchange giving the facts of the transaction, including basis surrendered and fair market value received. Missing the filing doesn’t change the tax treatment of the exchange itself, but it can trigger penalties and extend the statute of limitations on IRS examination of the return.
