Tax-Free Spin-Off: Section 355 Tests, Traps, and Consequences

A corporate spin-off qualifies for tax-free treatment under Internal Revenue Code Section 355 only if it clears a specific set of requirements, and the tax-free spin-off requirements are strict: both the parent and the subsidiary must be running an active five-year trade or business, the separation must have a real corporate business purpose unrelated to tax savings, the parent must distribute at least 80% control of the subsidiary, the historic shareholders must keep a continuing equity stake, the transaction cannot function as a device for bailing out earnings at capital gains rates, and it must steer clear of the 50%-acquisition traps in Sections 355(d) and 355(e). Miss any one of them and the whole distribution becomes fully taxable at both the corporate and shareholder level.¹

Active Trade or Business

Both the distributing (parent) corporation and the controlled (subsidiary) corporation must be actively conducting a trade or business immediately after the distribution. “Active conduct” means more than collecting checks. The corporation’s own officers and employees have to perform substantial managerial and operational functions. Owning rental property and hiring a third-party manager to run everything is unlikely to qualify; the business must involve meaningful day-to-day work by the corporation itself.¹

The statute also imposes a five-year lookback. The trade or business must have been actively conducted throughout the entire five-year period ending on the distribution date. A business acquired during that five-year window in a taxable transaction does not count. Congress did not want companies buying a qualifying business shortly before the spin-off just to pass this test. A business acquired through a prior tax-free reorganization can qualify; a straight purchase inside the five-year window disqualifies it.¹

The point of the rule is to prevent companies from using a spin-off to separate operating assets from passive investment holdings and then cash out the investment side at favorable rates.

Business Purpose

The spin-off must be motivated by a real, substantial corporate business purpose that has nothing to do with reducing federal income taxes. Treasury Regulations require that the purpose be “germane to the business” of the distributing corporation, the controlled corporation, or their affiliated group. A purpose that primarily benefits shareholders individually, rather than the corporate enterprise, will not satisfy this test unless the shareholder benefit and the corporate benefit are essentially the same thing.²

Acceptable business purposes include separating businesses to comply with regulatory requirements, raising capital through a public offering of the spun-off entity, resolving management disagreements that are harming operations, or eliminating meaningful operational inefficiencies. In every case the spin-off has to be the most practical way to achieve the goal. If the company could accomplish the same objective through a simpler method that did not involve a corporate separation, the IRS can reject the stated purpose as a pretext.

Purposes aimed at reducing federal income taxes are disqualifying. A vague claim that the separation will “unlock shareholder value,” standing alone, is generally not enough. The corporation needs to articulate a concrete operational or regulatory reason that independently justifies splitting into two companies.

Distribution of Control

The parent must distribute enough stock in the controlled corporation to constitute “control.” For Section 355 purposes, control is defined by Section 368(c): ownership of at least 80% of the total combined voting power of all voting stock, and at least 80% of the total shares of every other class of stock.³

The cleanest approach is distributing all the controlled corporation’s stock. The parent can retain some stock if it distributes at least the 80% threshold and demonstrates to the IRS that the retention is not part of a plan with tax avoidance as a principal purpose. In practice, the IRS scrutinizes retained stock closely, and most companies distribute 100% to avoid the fight.¹

Distributing only securities like bonds or notes, without any stock, does not satisfy the control requirement. The parent must distribute actual equity.

Continuity of Interest

Historic shareholders of the distributing corporation have to maintain a continuing equity stake in both the distributing and controlled corporations after the separation. The continuity of interest doctrine exists so that a spin-off reads as a genuine rearrangement of existing ownership rather than a disguised sale. If shareholders simply unload their new shares right away as part of a prearranged plan, the transaction starts to look like a sale of corporate assets.

Treasury regulations require that “a substantial part of the value of the proprietary interest” in the corporate enterprise be preserved through the transaction.⁴ In the reorganization context, the IRS has historically treated roughly 50% as the floor for ruling purposes, though that is an administrative practice rather than a bright-line statutory rule. A planned merger or acquisition of the spun-off entity shortly after the distribution can retroactively destroy continuity of interest, which is one reason the anti-abuse rules below matter so much.

The Device Test

Even when every other requirement is satisfied, the spin-off fails if it is used principally as a “device” to distribute corporate earnings at capital gains rates instead of as ordinary dividends. The device test is where the IRS looks hardest at what actually happened after the spin-off, not just what the plan documents say.¹

Treasury Regulations identify several factors that cut toward a device finding:

A sale of the distributing or controlled corporation’s stock shortly after the distribution. The larger the percentage sold and the shorter the gap, the stronger the evidence.
A pro rata distribution to all shareholders, which presents the greatest potential for disguising a dividend and is treated as stronger evidence than a non-pro-rata distribution.
Substantial assets in either corporation not used in a qualifying active business, particularly cash and liquid investments, suggesting the spin-off was designed to extract those assets at favorable rates.²

On the other side, a strong corporate business purpose weighs against a device finding. So does the fact that the distributing corporation is publicly traded and widely held, with no shareholder owning more than 5% of any class of stock. A post-distribution sale, by itself, does not establish a device if it was not negotiated or agreed upon before the distribution.¹

The 50% Acquisition Traps: Sections 355(d) and 355(e)

Clearing the five core requirements does not guarantee tax-free treatment. Congress added two anti-abuse provisions that can trigger corporate-level gain even when the distribution otherwise qualifies. Companies most often stumble here, and ignoring these rules can produce an enormous unexpected tax bill.

Section 355(d): Disqualified Distributions

Section 355(d) targets spin-offs where a shareholder bought a 50% or greater interest in the distributing or controlled corporation within the five years before the distribution. If, immediately after the distribution, any person holds “disqualified stock” representing 50% or more of the vote or value of either corporation, the distribution loses its tax-free status at the corporate level. Stock is “disqualified” if it was acquired by purchase during that five-year lookback.¹

In practice, a company cannot bring in a large new shareholder through a taxable stock purchase shortly before spinning off a subsidiary and still treat the spin-off as tax-free at the corporate level. The controlled corporation’s stock stops being “qualified property” for the corporate non-recognition rule, and the distributing corporation recognizes gain as if it sold the stock at fair market value.

Section 355(e): The Anti-Morris Trust Rule

Section 355(e) is broader. It applies whenever one or more persons acquire, directly or indirectly, a 50% or greater interest (by vote or value) in either the distributing or controlled corporation as part of a plan or series of related transactions that includes the distribution. When triggered, the distributing corporation recognizes gain on the distributed stock as if it had been sold at fair market value.¹

The statute creates a rebuttable presumption: any acquisition of a 50% or greater interest occurring within the four-year window starting two years before the distribution and ending two years after is presumed to be part of such a plan. The company can rebut that presumption by proving the distribution and the acquisition were not related, but the burden is steep.¹

This is the rule that prevents a company from spinning off a subsidiary and then immediately merging one of the resulting entities with an acquirer to achieve what is effectively a tax-free sale of a division. Shareholders still receive non-recognition under 355(e), but the corporate-level tax can be massive.

What Qualification Actually Gets You

When a spin-off satisfies every requirement, the distributing corporation does not recognize gain or loss on the distribution of the controlled corporation’s stock. Section 355(c) provides that non-recognition rule directly: distributing “qualified property” (stock or securities in the controlled corporation) is not a taxable event at the corporate level.¹

If the spin-off is structured as a “D” reorganization, where the parent first transfers assets to a new subsidiary and then distributes the subsidiary’s stock, Section 361 provides parallel non-recognition on the asset transfer. The parent recognizes no gain or loss on exchanging assets for stock in the new subsidiary, provided it distributes that stock to shareholders as part of the reorganization plan.⁵

Shareholders who receive stock in the controlled corporation also recognize no gain, loss, or dividend income. They end up owning shares in two companies instead of one, and the tax reckoning is deferred until they sell. Their original basis in the distributing stock gets split between the retained and new shares based on relative fair market values immediately after the distribution, and the holding period of the new shares tacks onto the holding period of the original stock under Section 1223.⁶

Two carve-outs still produce tax inside an otherwise qualifying deal. If the parent distributes non-qualifying property alongside the controlled stock, such as cash or debt instruments that do not count as securities, the parent recognizes gain on that boot equal to the excess of its fair market value over adjusted basis. And if the controlled corporation assumes liabilities from the parent whose total exceeds the aggregate adjusted basis of the assets transferred, the excess is treated as gain from a sale under Section 357.⁷

What Failure Costs

If the distribution misses any requirement, the parent is treated as having sold the controlled corporation’s stock at fair market value and recognizes gain accordingly. Shareholders are treated as having received a distribution of property, generally taxed as a dividend to the extent of the distributing corporation’s earnings and profits, with any excess treated as a return of capital or capital gain. The combined corporate and shareholder tax on an appreciated subsidiary can easily exceed what the companies would have paid in a straightforward asset sale, which is why most companies seeking tax-free treatment work from a reasoned “should” or “will” opinion from experienced tax counsel confirming each requirement is met before closing.
