A limitation on benefits clause is an article in a U.S. tax treaty that restricts who can actually claim the treaty’s reduced withholding rates. It exists to stop “treaty shopping,” where a company or individual from a country with no favorable U.S. treaty sets up a shell entity in a treaty country to route U.S.-source income through it. Under an LOB clause, anyone claiming treaty benefits must first pass at least one objective test showing a genuine connection to the treaty country. Fail every test, and the treaty does not apply to you.
What Failing the Tests Costs You
The statutory withholding rate on U.S.-source payments to foreign persons, including dividends, interest, and royalties, is 30%. A tax treaty may reduce that rate to 15%, 10%, 5%, or zero. If you cannot satisfy any LOB test in a given tax year, the treaty drops away and the 30% rate applies. Withholding happens at the source, before the money reaches you, so the cost of failing a test is immediate and hard to recover.
Who Qualifies Automatically as a Qualified Person
The most direct route to treaty benefits is fitting into one of the “qualified person” categories under Article 22 of the U.S. Model Income Tax Convention. These are the taxpayers whose ties to the treaty country are obvious enough that no further inquiry is needed.
- Individuals who reside in a treaty country qualify automatically.
- A treaty country’s national government, its states or provinces, local municipalities, and their agencies all qualify.
- Pension funds, charities, and similar tax-exempt organizations qualify if more than half of their beneficiaries are residents of either treaty country.1U.S. Department of the Treasury. U.S. Model Income Tax Convention
Corporations and other business entities need to clear one of the additional tests below.
The Publicly Traded Company Test
A corporation is a qualified person if its principal class of shares is regularly traded on a recognized stock exchange and either those shares are primarily traded on an exchange in its home country or the company’s primary place of management and control is there.1U.S. Department of the Treasury. U.S. Model Income Tax Convention The logic: shares in active public trading are too dispersed for treaty shopping to work.
“Regularly traded” has a numeric threshold. Under IRS guidance, at least 6% of the average outstanding shares in the principal class must have changed hands on a recognized exchange during the prior tax year.2Internal Revenue Service. Qualification for Treaty Benefits Under the Publicly Traded Test Nominal listings without real trading do not clear this bar.
Not every exchange counts. A recognized exchange includes any U.S. national securities exchange registered under the Securities Exchange Act of 1934, any U.S. over-the-counter market, and foreign exchanges that are government-supervised and exceed $1 billion in annual share trading volume in each of the three preceding calendar years.3eCFR. 26 CFR 1.883-2 – Treatment of Publicly-Traded Corporations The IRS Commissioner can disqualify an exchange with weak listing, disclosure, or trading standards even if it hits the dollar threshold. If a foreign exchange has multiple trading tiers, each tier is treated as a separate exchange and must meet the standards on its own.
The Ownership and Base Erosion Test
Privately held companies face a two-part test, and both parts must be satisfied in the same tax year.
The ownership prong: at least 50% of the company’s total voting power and share value must be held by qualified persons for at least half the days in a twelve-month period that includes the date the benefit is claimed.4Internal Revenue Service. Tax Treaty Table 4 – Limitation on Benefits Slipping below that 50% mark at the wrong point in the year costs you the benefits.
The base erosion prong: less than 50% of the company’s gross income can be paid or accrued as deductible amounts (such as interest, royalties, and service fees) to persons who are neither residents of either treaty country nor themselves entitled to treaty benefits.1U.S. Department of the Treasury. U.S. Model Income Tax Convention Arm’s-length payments made in the ordinary course of business for services or tangible property are excluded from that calculation. Without this prong, a company could satisfy the ownership test on paper while stripping most of its taxable income out to low-tax jurisdictions through deductible payments.
The Active Trade or Business Test
An entity that flunks the qualified person tests can still claim treaty benefits if it runs a real business in its home country and the U.S.-source income connects to that business.
The business has to involve more than holding investments. Manufacturing, selling goods, providing professional services, or operating physical locations all qualify. Collecting dividends, interest, and capital gains from a passive portfolio does not.1U.S. Department of the Treasury. U.S. Model Income Tax Convention
The income also has to connect to that business. It must flow from or be incidental to the active operation in the home country. When the income comes from a related party (for example, a subsidiary paying dividends to its parent) a substantiality requirement kicks in: the home-country business must be substantial relative to the activity generating the income in the source country.1U.S. Department of the Treasury. U.S. Model Income Tax Convention A small consulting office cannot anchor hundreds of millions in treaty-benefited payments from an affiliate on the other side.
The Derivative Benefits Test
The derivative benefits test looks through the entity to its owners. If the owners would have received the same or better treaty rates on their own, the entity is not penalized for sitting between them and the income.
To pass, at least 95% of the entity’s shares (by voting power and value) must be held by seven or fewer “equivalent beneficiaries.”1U.S. Department of the Treasury. U.S. Model Income Tax Convention An equivalent beneficiary is a resident of a third country whose own U.S. treaty entitles it to the same or lower withholding rate on the type of income in question. The rate available to the entity cannot exceed what each equivalent beneficiary would have received on a direct payment, so you cannot upgrade your tax treatment by inserting a corporate layer in a better treaty jurisdiction.
Asking the IRS for a Discretionary Determination
When an entity fails every objective test, one option remains: asking the IRS competent authority to grant treaty benefits on a case-by-case basis under Revenue Procedure 2015-40. As of January 2026, the user fee is $66,800.5Internal Revenue Service. Internal Revenue Bulletin 2026-01 Within 30 days of receiving a complete submission, the IRS notifies the applicant whether it will accept the request for review.6Internal Revenue Service. Revenue Procedure 2015-40 – Procedures for Requesting Competent Authority Assistance Under Tax Treaties
To win, the applicant must demonstrate three things: that it genuinely does not qualify under any objective LOB test, that it has a “substantial nontax nexus” to the treaty country, and that neither the applicant nor its owners will use the treaty inconsistently with its purposes.6Internal Revenue Service. Revenue Procedure 2015-40 – Procedures for Requesting Competent Authority Assistance Under Tax Treaties The substantial nontax nexus draws most of the scrutiny. The IRS examines the company’s history of business activity, customers, employees, capital assets, and sources of supply in the treaty country. Pointing to favorable local tax laws or the country’s broader treaty network is not enough.
Two features catch applicants off guard. A denial is final and not subject to administrative appeal. And a favorable determination is not permanent: the applicant must file a triennial statement every three years confirming the underlying facts have not materially changed, and any material change in facts or law must be reported to the IRS within 90 days.6Internal Revenue Service. Revenue Procedure 2015-40 – Procedures for Requesting Competent Authority Assistance Under Tax Treaties
How You Actually Claim the Benefit: Form 8833
Claiming treaty benefits under an LOB clause is not automatic. Any taxpayer taking a position on a U.S. return that a treaty overrides or modifies the Internal Revenue Code must disclose it on Form 8833, with a separate form for each treaty-based position in a given year.7Office of the Law Revision Counsel. 26 USC 6114 – Treaty-Based Return Positions
The form asks you to identify which LOB test you rely on, explain why you meet it, and estimate the income affected.8Internal Revenue Service. Form 8833 – Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b) Attach it to your income tax return (Form 1040-NR for nonresident individuals, Form 1120-F for foreign corporations). If you would not otherwise need to file a return, you have to file one anyway just to make the disclosure.
Some positions are exempt from the Form 8833 requirement, including certain individual employment income, pensions, social security, and income earned by students, teachers, and diplomats. Treaty-reduced withholding on dividends, interest, and royalties is also exempt if the income was properly reported on Form 1042-S and the recipient meets specific conditions, such as being a direct account holder at a U.S. financial institution or receiving less than $500,000 in aggregate from a single payor. Treaty positions already disclosed by a partnership or trust on behalf of its partners or beneficiaries need not be reported again by the individual.8Internal Revenue Service. Form 8833 – Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b)
Penalties for Skipping the Disclosure
Missing the Form 8833 disclosure triggers a separate penalty on top of any tax owed. Individuals face $1,000 per failure and C corporations face $10,000 per failure.9Office of the Law Revision Counsel. 26 USC 6712 – Failure to Disclose Treaty-Based Return Positions Because each position requires its own form, a taxpayer with several undisclosed treaty positions can face stacked penalties in a single year.
The IRS can waive the penalty if the taxpayer shows reasonable cause and good faith.9Office of the Law Revision Counsel. 26 USC 6712 – Failure to Disclose Treaty-Based Return Positions Ignorance of the filing requirement, standing alone, generally does not clear that bar. The nondisclosure penalty is imposed in addition to any other penalty and can stack on top of accuracy-related penalties or underpayment interest if the underlying treaty claim also proves wrong.
One Thing to Know About Other Countries’ Anti-Abuse Rules
The LOB clause is not the only anti-abuse tool in modern tax treaties. Since the OECD’s Base Erosion and Profit Shifting project in 2015, many countries have adopted a Principal Purpose Test that denies treaty benefits when obtaining them was one of the main reasons for an arrangement. The United States has generally stuck with LOB because it relies on objective tests rather than subjective judgments about intent. Most U.S. treaties contain a detailed LOB article without a standalone PPT, but other jurisdictions (particularly in Europe) apply a PPT. If your income crosses multiple treaty networks, passing the U.S. LOB does not guarantee you pass a PPT elsewhere, and the reverse is also true.
