IRS Rules on Tax-Free Spin-Off Under Sections 355 and 368 for S Corporation

IRS Greenlights Tax-Free Spin-Off for S Corporation Shareholders

The IRS issued a non-precedential Private Letter Ruling (PLR-102725-26) granting tax-free treatment under Section 355 and Section 368 for an S corporation’s spin-off of a subsidiary. The ruling confirms the transaction qualifies as a tax-free stock distribution under Section 355(a)(1), contingent on statutory requirements like control, active trade or business, and continuity of interest. The IRS did not address the business purpose requirement. While the ruling offers guidance for S corporation shareholders, its non-precedential status restricts broader applicability.

The Proposed Transaction: Splitting an S Corporation's Business

Distributing, a State A corporation electing S status under Section 1362(a), operated Business A with three shareholders: Shareholder A owned a%, while Shareholders B and C each owned b%. To separate competing business lines, Distributing proposed a multi-step transaction finalized on July 15, 2026.

First, Distributing formed Controlled as a State A corporation and elected to treat it as a qualified Subchapter S subsidiary (QSub) under Section 1361(b)(3). A QSub is a 100%-owned subsidiary disregarded for federal tax purposes, meaning its income and losses flow directly to Distributing. This election took effect immediately upon Controlled’s incorporation.

Next, Distributing transferred the Controlled Assets—specifically the operational components of Business A—to Controlled in exchange for all of Controlled’s stock and for Controlled’s assumption of all liabilities tied to those assets. This transfer qualified as a Section 351 transaction, which defers gain recognition when property is exchanged solely for stock in a controlled corporation. The liabilities assumed by Controlled did not trigger immediate tax under Section 357(a), as they did not exceed Distributing’s adjusted basis in the transferred assets.

Following the transfer, Distributing distributed all of Controlled’s stock to Shareholders B and C in exchange for their Distributing shares. This distribution was structured as a Section 355 spin-off, designed to separate Distributing’s remaining business (now solely Business A) from the newly formed Controlled entity. Controlled then elected its own S status under Section 1362(a), effective immediately after the distribution.

Post-transaction, Shareholder A retained sole ownership of Distributing, while Shareholders B and C became the sole owners of Controlled. Critically, no continuing arrangements—such as management overlap, shared employees, or intercompany agreements—existed between Distributing and Controlled after the distribution. The separation was complete, with each entity operating independently under distinct ownership and management structures.

Key Representations That Secured IRS Approval

The IRS approved the spin-off based on Distributing’s representations addressing core concerns under Section 355, including the device test and anti-Morris Trust rule under Section 355(e). These aligned with frameworks in Rev. Proc. 2017-52 and Rev. Proc. 2025-30, ensuring the transaction avoided disguised sales, liquidations, or tax-motivated structures while maintaining operational independence.

Key safeguards included:

1. Post-Distribution Restrictions: Shareholders and corporations agreed not to sell, repurchase stock, or liquidate entities post-spin-off, except in the ordinary course of business. This prevented prearranged sales or self-dealing, as prohibited under Section 355(e) and Section 355(a)(1)(B).

2. Asset Threshold: Both entities maintained business assets exceeding 80% of total assets post-distribution, excluding investment assets or excess cash. This satisfied the active trade or business (ATB) requirement under Section 355(b).

3. No Pre-Existing Acquisition Plans: No agreements or negotiations for acquisitions existed within two years prior to the distribution, addressing the anti-Morris Trust rule under Section 355(e).

IRS Ruling: Tax-Free Treatment Under Sections 355 and 368

The IRS issued 13 rulings confirming tax-free treatment for the spin-off, treating the transaction as a Type D reorganization under Section 368(a)(1)(D). The IRS ruled that:

• No gain or loss was recognized on the asset transfer (Contribution) under Section 361(a) or on Controlled’s issuance of stock under Section 1032(a).
• Basis and holding periods followed statutory mandates: Controlled’s basis in assets matched Distributing’s pre-contribution basis (Section 362(b)), and its holding period included Distributing’s (Section 1223(2)). Shareholders’ basis in Controlled stock was determined under Section 358(a), with holding periods tacking under Section 1223(1).
• Earnings and profits (E&P) were allocated between Distributing and Controlled under Section 312(h) and Treas. Reg. § 1.312-10(a).
• Controlled’s QSub election terminated post-spin-off, but its prior treatment under Section 1361(b)(3) remained valid. Distributing’s momentary ownership of Controlled stock did not disqualify Controlled’s S election under Section 1361.

The IRS’s analysis confirmed compliance with continuity of interest, control requirements, and the absence of boot or pre-existing acquisition plans under Section 355(e).

Why the IRS Did Not Rule on Business Purpose

The IRS declined to address the business purpose requirement under Treas. Reg. § 1.355-2(b), deferring judgment to the audit process. Taxpayers face risk here, as the requirement is critical for tax-free treatment under Section 355(a)(1)(D). For instance, the Tax Court denied tax-free treatment in Kimbell v. Commissioner (T.C. Memo. 2020-158) where tax avoidance was the sole purpose. Taxpayers should document a non-tax corporate business purpose via contemporaneous records (e.g., board resolutions, strategic plans) to strengthen their position.

Implications for S Corporations and Shareholders

The IRS’s non-precedential ruling in PLR-102725-26 provides guidance for structuring tax-free spin-offs under Section 355, but taxpayers must address the business purpose requirement through contemporaneous documentation (e.g., board resolutions, strategic plans) to avoid audit risks. The ruling’s silence on this requirement highlights the need for careful documentation.

Key compliance risks include:

• Active trade or business (ATB) requirement: Both entities must operate real businesses for at least five years (Treas. Reg. § 1.355-3(b)).
• Control requirement: The distributing corporation must own ≥80% of the controlled corporation’s stock (Section 355(a)(1)(A)).
• Anti-Morris Trust rule: Acquisitions post-spin-off must not be part of a pre-existing plan (Section 355(e)).

For shareholders, basis and holding period adjustments under Section 358 and Section 1223 are critical. Boot (e.g., cash) in the distribution may trigger tax under Section 356. The ruling’s non-precedential status means taxpayers should seek additional IRS guidance (e.g., technical advice memoranda) to mitigate risks.
