A reverse hybrid entity is a business entity that the country where it was formed treats as a fiscally transparent pass-through, while an investor’s home country treats the same entity as a separate, opaque corporation. That single classification mismatch can let interest or royalty income slip past both tax systems, because each country assumes the other is picking it up. The U.S. response runs on two tracks: Internal Revenue Code Section 267A denies the payor’s deduction on certain payments made to or through these structures, and Section 894(c) shuts off treaty-based withholding relief when income flows through them.
Where the Mismatch Comes From
The mismatch usually starts with the “check-the-box” regulations under Treasury Regulation ยง301.7701-3. An eligible entity with two or more owners can elect to be treated as either a corporation or a partnership for U.S. federal tax purposes, and a single-owner entity can elect between corporation status and being disregarded.1eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities
A foreign country has no obligation to respect the U.S. election. So the same entity can be a pass-through in one system and a corporation in the other. The IRS has acknowledged that this is a direct consequence of the elective regime: a foreign entity can be transparent for one country’s tax purposes and opaque for the other’s.2Internal Revenue Service. Overview of Entity Classification Regulations (Check-the-Box)
Reverse Hybrid vs. Regular Hybrid
Direction matters. A regular hybrid is treated as transparent in the United States but as a corporation by the foreign country where it resides. A reverse hybrid flips that arrangement: the entity is transparent under the law of the country where it was formed, but the investor’s country sees a corporation.2Internal Revenue Service. Overview of Entity Classification Regulations (Check-the-Box)
Section 267A itself defines “hybrid entity” broadly enough to reach both directions. Under the statute, a hybrid entity is one that is either treated as fiscally transparent for U.S. tax purposes but not under the foreign country’s tax law, or treated as transparent under the foreign country’s law but not for U.S. purposes.3U.S. Code. 26 USC 267A – Certain Related Party Amounts Paid or Accrued in Hybrid Transactions or With Hybrid Entities The Treasury regulations then narrow in, defining a “reverse hybrid” as an entity that is fiscally transparent where it was organized but not fiscally transparent from the perspective of an investor.4Federal Register.

A Worked Example
Picture a parent in Country Y that owns an entity organized in Country X. Country X treats that entity as a pass-through and does not tax it, expecting the Country Y owner to report the income. Country Y treats the entity as a separate corporation and does not flow the income through to the parent until it sees a distribution. A U.S. subsidiary then pays deductible interest to the Country X entity. The U.S. subsidiary takes its deduction. Country X taxes nothing because the entity is transparent there. Country Y taxes nothing because it is waiting for a distribution from what it views as a foreign corporation. The income vanishes from every base.
The Underlying Harm: Deduction Without Inclusion
International tax practitioners call the target outcome “deduction/no inclusion,” or D/NI. The payor takes a current deduction and reduces its taxable income. No jurisdiction picks up the matching income on the receiving side. A related outcome is double non-taxation, where the mismatch interacts with treaty rules or other domestic provisions so that income escapes tax in both the payor’s country and the recipient’s country. Section 267A exists to break that pattern by removing the deduction at the U.S. end.
Section 267A: Denying the Deduction
Section 267A came in with the Tax Cuts and Jobs Act of 2017. The core rule: no deduction is allowed for any “disqualified related party amount” paid or accrued through a hybrid transaction or by or to a hybrid entity.5Office of the Law Revision Counsel. 26 USC 267A – Certain Related Party Amounts Paid or Accrued in Hybrid Transactions or With Hybrid Entities
A “disqualified related party amount” is interest or royalty paid to a related party where either the amount is not included in the recipient’s income under the tax law of the country where the recipient resides, or the recipient gets a deduction for the same amount under that country’s law.5Office of the Law Revision Counsel. 26 USC 267A – Certain Related Party Amounts Paid or Accrued in Hybrid Transactions or With Hybrid Entities Both prongs go after the same underlying result: a payment that shrinks one country’s tax base without growing another’s.
Payments and Parties Covered
The statute reaches interest and royalty payments, read broadly to include amounts paid for the use of money and for the use of intangible property, as well as any other amounts treated as interest or royalties under applicable tax law. The rules apply to payments made by U.S. persons, including controlled foreign corporations, to related foreign persons.
“Related party” for Section 267A purposes borrows the definition in Section 954(d)(3): more-than-50% direct or indirect ownership of stock, capital, or profits.5Office of the Law Revision Counsel. 26 USC 267A – Certain Related Party Amounts Paid or Accrued in Hybrid Transactions or With Hybrid Entities Other parts of the tax code use higher thresholds (80% or more) for “related” or “controlled group” tests, so the 50% line here catches more relationships than many taxpayers expect.
Structured Transactions Between Unrelated Parties
The related-party requirement has a backstop. Congress instructed Treasury to write rules bringing certain “structured transactions” within Section 267A even where the parties are not related by ownership, on the theory that taxpayers could otherwise route payments through unrelated intermediaries to engineer the same D/NI outcome.5Office of the Law Revision Counsel. 26 USC 267A – Certain Related Party Amounts Paid or Accrued in Hybrid Transactions or With Hybrid Entities
How the Deduction Denial Applies to Reverse Hybrids
The 2020 final regulations set out a specific test for reverse hybrid structures. A payment to a reverse hybrid is treated as a “disqualified hybrid amount” to the extent an investor whose country treats the reverse hybrid as opaque does not include the payment in income, and that non-inclusion is attributable to the payment being made to the reverse hybrid rather than to some independent reason. The regulations ask a counterfactual question: would the investor’s non-inclusion still occur if the investor’s country treated the reverse hybrid as transparent? If not, the mismatch traces to the reverse hybrid structure, and the deduction goes away.4Federal Register. Rules Regarding Certain Hybrid Arrangements
The regulations also reach indirect payments. Where a payment is made to an entity owned by a reverse hybrid, and the intermediate entities are all transparent under the relevant investor’s tax law, the payment is treated as made to the reverse hybrid for purposes of the deduction denial. One narrow exception: if a taxable branch located in the country where the reverse hybrid was organized picks up the payment in its own income, the deduction denial does not apply, because the income is being taxed somewhere.4Federal Register. Rules Regarding Certain Hybrid Arrangements
The Imported Mismatch Backstop
Section 267A also disallows deductions for “disqualified imported mismatch amounts.” This closes off a workaround in which a taxpayer routes a payment through a third-country hybrid arrangement to fund what looks, on its face, like a plain deductible payment between two non-hybrid entities. If the end result is a D/NI outcome, the deduction is denied no matter how many intermediate steps sit between the payor and the ultimate benefit.
Section 894(c): Losing Treaty Benefits
Deduction denial is only half of the U.S. answer. Section 894(c) separately governs whether payments made through a fiscally transparent entity qualify for reduced withholding rates under a U.S. income tax treaty. That matters because interest and dividends paid to foreign persons are otherwise subject to withholding tax that treaties often cut sharply or eliminate.
Under Section 894(c), a foreign person loses treaty-based withholding relief on income derived through a fiscally transparent entity if three conditions are met: the foreign person’s home country does not treat the income as belonging to that person; the applicable treaty has no provision addressing income derived through partnerships; and the foreign country does not tax distributions of that income from the entity to the person.6Office of the Law Revision Counsel. 26 USC 894 – Income Affected by Treaty
The statute also directs Treasury to write regulations reaching a broader category: taxpayers receiving payments through any entity (including disregarded entities and grantor trusts) that is treated as transparent for U.S. purposes but as opaque under the tax law of the taxpayer’s home country.6Office of the Law Revision Counsel. 26 USC 894 – Income Affected by Treaty This second prong is aimed straight at the reverse hybrid pattern.
Interactions and Proof
Section 267A does not sit off by itself. When a controlled foreign corporation’s payment is denied a deduction, the CFC’s earnings and profits have to be recalculated, and that recalculation can affect Subpart F income and GILTI inclusions for U.S. shareholders.
The payor carries the burden of proving that the foreign recipient in fact included the payment in income. If the recipient reported it under its local tax law, the payment generally is not a disqualified related party amount and the deduction survives. Getting to that conclusion, though, requires documentation of the recipient’s foreign tax treatment, and that is where much of the day-to-day compliance work sits.
