The device test under Internal Revenue Code Section 355 asks whether a corporate spin-off or split-off was “used principally as a device for the distribution of the earnings and profits” of the parent, the subsidiary, or both. If the answer is yes, the distribution loses its tax-free status. The IRS decides the question by weighing evidence of device against evidence of non-device in a facts-and-circumstances analysis, and no single factor is automatically fatal.1Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation
Why the Test Still Bites
Many people assume the device rule exists to stop shareholders from converting ordinary dividend income into lower-taxed capital gains. That rationale has weakened. Qualified dividends and long-term capital gains are both capped at 20 percent for most shareholders, so the rate spread that once drove the rule has largely closed.2Internal Revenue Service. Topic No. 409, Capital Gains and Losses
The prohibition survives because two other advantages remain. A shareholder who sells stock received in a spin-off recovers allocated basis before recognizing gain; a straight dividend offers no basis offset and is fully taxable up to earnings and profits. And capital gains from a post-distribution sale can be absorbed by existing capital losses, while a dividend cannot. Treasury regulations explicitly recognize that “a device can include a transaction that effects a recovery of basis” even when dividend and capital gain rates are identical.3Federal Register. Guidance Under Section 355 Concerning Device and Active Trade or Business
The “Not Principally” Balancing Standard
The statute does not require zero device characteristics. It requires that the distribution was “not used principally as a device.”1Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation That one word turns the analysis into a balancing test. A spin-off can carry real device indicators and still pass, provided the non-device evidence is stronger. Most disputes with the IRS play out inside that margin.
Factors Pointing Toward a Device
Treasury regulations identify several characteristics that serve as evidence of a disguised dividend.4eCFR. 26 CFR 1.355-2 – Limitations on the Nonrecognition of Gain or Loss on Distributions of Stock and Securities of Controlled Corporations
Pro Rata Distributions
A distribution in which every shareholder receives subsidiary stock in proportion to existing ownership is the strongest structural indicator of device. The regulations state that a pro rata distribution “presents the greatest potential for the avoidance of the dividend provisions of the Code.”5eCFR. 26 CFR 1.355-2 – Limitations Nobody’s relative stake changes, so the separation resembles handing out cash.
Non-pro-rata distributions carry less risk because they actually change shareholder positions. This is one reason split-offs, where a group of shareholders swaps parent stock for subsidiary stock, tend to fare better on the device factor than pro rata spin-offs.
Post-Distribution Sales
Selling the distributed stock shortly after the spin-off is the most damaging behavioral indicator. The tighter the gap between distribution and sale, the more the sequence looks like a two-step dividend: receive stock tax-free, then cash out at capital gains rates with a basis offset.
Sales negotiated or agreed on before the distribution are treated as near-conclusive evidence of a device. The statute protects only unplanned sales: “the mere fact that subsequent to the distribution stock . . . are sold or exchanged by all or some of the distributees (other than pursuant to an arrangement negotiated or agreed upon prior to such distribution) shall not be construed to mean that the transaction was used principally as such a device.”1Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation Ruling requests typically include representations from the distributing corporation and major shareholders confirming no plan or intent to dispose of the controlled stock.
Nonbusiness Assets
The ratio of assets used in an active trade or business to assets that serve no operational purpose — cash, portfolio securities, excess real estate — is a direct device indicator. Liquid assets that have nothing to do with running the business look like value that could have gone out as cash but was instead packaged inside a tax-free stock distribution.5eCFR. 26 CFR 1.355-2 – Limitations
Imbalance between the two entities is especially suspicious. When the parent keeps the operating business and the subsidiary ends up holding mostly cash and investments, the structure looks like a vehicle for parking distributable value where shareholders can sell it. The regulations note that a difference in nonbusiness asset ratios is less concerning when the distribution is non-pro-rata and the gap is needed to equalize the value exchanged.5eCFR. 26 CFR 1.355-2 – Limitations
Proposed Numerical Thresholds
In 2016 the IRS proposed specific thresholds for evaluating nonbusiness assets. These have not been finalized, but they map the framework the IRS applies.
Nonbusiness assets are generally not treated as device evidence if both the distributing and controlled corporations hold nonbusiness assets equal to less than 20 percent of total assets. A difference in nonbusiness asset percentages between the two entities is not device evidence if the gap is less than 10 percentage points.6Internal Revenue Service. Internal Revenue Bulletin 2016-31
At the other end, the proposed rules create a per se device category that treats the distribution as a device regardless of the other factors:
- One corporation holds 66⅔ percent or more but less than 80 percent nonbusiness assets, and the other holds less than 30 percent.
- One corporation holds 80 percent or more but less than 90 percent, and the other holds less than 40 percent.
- One corporation holds 90 percent or more, and the other holds less than 50 percent.
The proposed rules also require that assets used in a five-year active trade or business represent at least 5 percent of total assets for both entities.6Internal Revenue Service. Internal Revenue Bulletin 2016-31 Falling below that floor could disqualify the distribution entirely.
Factors Weighing Against a Device
Regulations identify several characteristics that counterbalance device evidence, and when they are strong enough they overcome significant device indicators.
Corporate Business Purpose
A real, substantial business reason for the separation is the most powerful non-device factor. Recognized purposes include letting each business focus on its own operations, resolving disputes between shareholder groups, complying with regulatory requirements, and improving access to capital markets.4eCFR. 26 CFR 1.355-2 – Limitations on the Nonrecognition of Gain or Loss on Distributions of Stock and Securities of Controlled Corporations The “fit and focus” rationale is the most commonly invoked purpose in large spin-offs, and the IRS has recognized it as valid even where the separation also benefits shareholders personally, provided the corporate-level purpose is real.7Internal Revenue Service. Revenue Ruling 2003-52
Shareholder dispute resolution works particularly well in split-offs, where one group takes the subsidiary and the other keeps the parent. The non-pro-rata structure weakens the pro rata device factor and reinforces the business purpose at the same time.
Publicly Traded Stock and Dispersed Ownership
Distributions by publicly traded corporations with no single shareholder or small group holding more than 5 percent of the stock are significantly less likely to be treated as a device. When ownership is scattered across institutions, index funds, and thousands of individuals, a coordinated plan to extract corporate earnings is not a plausible driver of the transaction.5eCFR. 26 CFR 1.355-2 – Limitations
Corporate Shareholders With a Dividends-Received Deduction
When distributees are themselves corporations entitled to a dividends-received deduction, the device concern largely evaporates. A corporate shareholder that could receive an actual dividend and deduct most of it under the DRD has little reason to engineer a spin-off as a substitute. The regulations treat this as a non-device factor because it removes the economic motivation the test is designed to catch.
Distributions Presumed Not to Be a Device
Three categories receive a regulatory presumption that they are not a device, regardless of the other factors. The presumptions can be overcome in certain multi-controlled-corporation distributions designed to facilitate a subsequent sale, but in most cases they provide strong protection.5eCFR. 26 CFR 1.355-2 – Limitations
- No earnings and profits. If neither the distributing nor the controlled corporation has accumulated or current E&P at the time of distribution, the transaction cannot serve as a device for distributing E&P that does not exist. Any direct cash distribution would have been a nontaxable return of capital.
- Section 302(a) exchange treatment. If the distribution would qualify as a redemption treated as a sale or exchange under Section 302(a), typically a non-pro-rata split-off in which a shareholder completely terminates their interest in the parent, the presumption applies. The shareholder is genuinely trading one investment for another.8Office of the Law Revision Counsel. 26 USC 302 – Distributions in Redemption of Stock
- Section 303(a) estate redemptions. When a distribution would qualify as a redemption to pay estate taxes and funeral expenses under Section 303(a), the presumption applies. The distribution responds to a specific financial pressure on the estate rather than a tax planning objective.5eCFR. 26 CFR 1.355-2 – Limitations
What Happens When a Distribution Fails
Failing the device test knocks the distribution out of Section 355, and the consequences hit both the corporation and its shareholders.
The distributing corporation loses the Section 355(c) exemption from gain recognition. Section 311(b) then requires it to recognize gain as if it had sold the distributed property at fair market value.9Office of the Law Revision Counsel. 26 USC 311 – Taxability of Corporation on Distribution Subsidiary stock in a major spin-off almost always carries significant built-in appreciation, so the corporate-level bill can be very large.
For shareholders, the distribution is reclassified under Section 301. The fair market value of the stock received is treated as a dividend to the extent of the distributing corporation’s earnings and profits. Any excess reduces stock basis, and anything beyond that is capital gain.10Office of the Law Revision Counsel. 26 USC 301 – Distributions of Property In a mature corporation with decades of accumulated E&P, most or all of the distribution ends up taxed as a dividend.
On top of the reclassified income, the IRS can impose a 20 percent accuracy-related penalty under Section 6662 on any resulting underpayment. The penalty applies to underpayments stemming from negligence, disregard of rules, or a substantial understatement of income tax, which for most corporations means an understatement exceeding the lesser of 10 percent of the correct tax or $10 million.11Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments A private letter ruling or a well-reasoned tax opinion obtained before the transaction provides important protection against those penalties.
Getting Comfort in Advance
Because the stakes are steep, many corporations request a private letter ruling before completing a Section 355 transaction. The IRS treats Section 355 as an area where it will issue letter rulings even on issues that might otherwise be considered settled by existing authority.12Internal Revenue Service. Internal Revenue Bulletin 2026-01
Since 2016, the IRS has been willing to rule on both business purpose and device issues in Section 355 transactions, reversing a long-standing no-rule policy on those topics. It addresses “significant issues” under the business purpose and device rules, provided the issues are not purely factual determinations that can only be resolved by examining post-transaction events. A thorough ruling request affirmatively addresses every device factor present and explains why the non-device factors outweigh them. When a ruling is not sought, a detailed tax opinion covering the same analysis strengthens the taxpayer’s position against accuracy-related penalties.
A Separate Trap: Section 355(e)
Passing the device test is not the end of the analysis. Section 355(e), sometimes called the anti-Morris Trust rule, imposes corporate-level gain when 50 percent or more of the voting power or economic value of either the distributing or the controlled corporation is acquired as part of a plan that includes the spin-off, even though the distribution itself remains tax-free to shareholders.1Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation A rebuttable presumption treats any acquisition of that size within two years before or after the distribution as part of a plan, subject to safe harbors. Device planning and 355(e) planning tend to overlap in practice, because post-distribution sales that raise one concern usually raise the other.
