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

Key Takeaways

• IRC Section 368(a)(1)(B) defines Type B reorganization as acquisition of target stock by acquirer in exchange solely for voting stock of acquirer or acquirer’s parent.
• The Solely Voting Stock requirement is strict. Any non-voting consideration, even nominal cash for fractional shares, disqualifies the transaction. Treasury Regulations include narrow exceptions for cash paid for fractional shares.
• 80 percent control test: acquirer must own at least 80 percent of voting power and 80 percent of each class of non-voting stock immediately after the transaction.
• Creeping acquisitions qualify under Type B if multiple acquisitions during a 12 month period collectively achieve 80 percent control, provided each acquisition uses solely voting stock.
• Target remains a separate legal entity after Type B reorganization, becoming a wholly-owned subsidiary of the acquirer. This preserves target contracts, licenses, and operating permits without consent requirements.
• No COI test applies to Type B reorganizations because the solely voting stock requirement automatically satisfies the continuity of interest doctrine.
• Section 368(c) defines control as ownership of at least 80 percent of voting power plus 80 percent of each class of non-voting stock. The test is more restrictive than the 50 percent voting control standard used elsewhere in tax law.

Conclusion

Type B reorganization remains the cleanest tax-free acquisition structure for all-stock transactions where the buyer can use solely voting stock as consideration and acquire 80 percent control of target. The transactions that qualify cleanly share three characteristics. The parties structure consideration as solely voting stock with only narrow Treasury Regulation-permitted fractional share cash. The acquirer achieves 80 percent of target voting power and 80 percent of each class of non-voting stock immediately after the transaction. The documentation includes explicit tax representations, IRC section references, and a qualified tax opinion when the transaction is sophisticated enough to warrant opinion fees. The Type B structure pays for itself in middle-market deals through complete tax deferral at the shareholder level, preservation of target as a separate legal subsidiary with continued contract and license relationships, and efficient stock-for-stock combination that aligns target shareholders with combined entity success.

Frequently Asked Questions

What is a Type B reorganization?

A Type B reorganization is a tax-free stock-for-stock acquisition under Internal Revenue Code Section 368(a)(1)(B). The acquirer exchanges its voting stock (or voting stock of its parent corporation) for stock of the target corporation. After the transaction, the acquirer must own at least 80 percent of target voting power plus 80 percent of each class of target non-voting stock. The structure requires solely voting stock as consideration with narrow exceptions for fractional share cash.

What is the Solely Voting Stock requirement?

Consideration must be solely voting stock. No cash, debt, property, or non-voting stock is permitted. The strict requirement ensures target shareholders maintain continuing proprietary interest in the combined entity. Treasury Regulations include narrow exceptions for cash paid to fractional shareholders (rounding cash for fractional shares does not disqualify the transaction). Any other cash or non-voting consideration disqualifies Type B treatment entirely, even small amounts. Practitioners structure Type B reorganizations carefully because the all-or-nothing requirement creates execution risk.

What is the 80 percent control test?

IRC Section 368(c) defines control as ownership of at least 80 percent of total combined voting power plus at least 80 percent of total shares of all classes of non-voting stock. Acquirer must satisfy both prongs immediately after the Type B reorganization. If target has only voting common stock, acquirer must own 80 percent of voting common after the transaction. If target has voting common and non-voting preferred, acquirer must own 80 percent of voting common AND 80 percent of non-voting preferred.

Are creeping acquisitions allowed under Type B?

Yes, with restrictions. Creeping acquisitions qualify under Type B if the acquirer makes multiple acquisitions during a 12 month period and the cumulative acquisitions reach 80 percent control. Each individual acquisition must use solely voting stock. The 12 month rule prevents stretching multiple smaller transactions over years to avoid the 80 percent threshold. Treasury Regulations require integrated transaction analysis to determine which acquisitions count toward the 80 percent test.

When should I use Type B versus Type A reorganization?

Use Type B when consideration is solely voting stock, when target shareholders want continued equity participation, and when target has contracts or licenses that would terminate or trigger consent requirements upon merger. Use Type A when the deal requires cash or debt consideration (up to 60 percent boot allowed), when shareholder vote requirements favor the merger structure, or when dissenting shareholders need to be bound through statutory merger mechanics rather than individual participation.

What tax consequences apply to target shareholders?

Target shareholders recognize no gain. Shareholders defer 100 percent of any capital gain by taking carryover basis in acquirer stock received. Basis equals original basis in target stock surrendered. The deferred gain remains embedded in acquirer stock until the shareholder later disposes of the stock through sale, gift, or other taxable event. Holding period in acquirer stock includes the holding period in target stock for capital gains purposes, allowing immediate long-term capital gain treatment if the underlying target stock met the holding period requirement.

Does Type B require a continuity of interest test?

No. The solely voting stock requirement automatically satisfies the continuity of interest doctrine because target shareholders maintain 100 percent of their proprietary interest through the acquirer stock received. The COI test that applies to Type A reorganizations (requiring at least 40 percent equity consideration) is not relevant for Type B because consideration is by definition 100 percent voting stock.

What happens to target after a Type B reorganization?

Target continues to exist as a separate legal entity, becoming a wholly-owned (or majority-owned) subsidiary of the acquirer. The structure preserves target contracts, licenses, operating permits, and any third-party relationships without triggering consent requirements. This makes Type B particularly useful for businesses with regulated licenses (alcohol, broadcasting, healthcare), government contracts, or any operations where preserving the target legal entity matters.

Can I use Type B with cash for fractional shares?

Yes, with narrow Treasury Regulation exceptions. Cash paid to round up or down for fractional shares does not disqualify the transaction. The exception applies only to legitimate fractional share cash where the exchange ratio produces fractional results that need to be settled in cash. Any other cash payment (sweetener consideration, dissenter buyouts, transaction expense reimbursement) disqualifies Type B treatment. Practitioners draft the exchange ratio carefully to minimize fractional share situations.

What is IRC Section 382 and how does it affect Type B?

IRC Section 382 limits the acquirer’s ability to use target’s net operating loss carryforwards and built-in losses following a Type B reorganization (any ownership change of 50 percent or more triggers the limitation). The Section 382 limitation equals the long-term tax-exempt rate (currently around 4 percent) multiplied by the fair market value of target stock immediately before the ownership change. The limitation typically reduces NOL utilization to a small fraction of target’s pre-transaction losses each year. IRC Section 383 imposes similar limitations on tax credit carryforwards.
