Form 8833, Treaty-Based Return Position Disclosure, is the IRS form you attach to your return when you rely on a tax treaty to override or modify the Internal Revenue Code and that reduces your US tax. You file a separate form for each treaty position. If you don't disclose a position you were required to, the penalty is $1,000, or $10,000 for a C corporation.
Plenty of treaty claims don't need a Form 8833 at all, and some that look routine do. The difference comes down to a list of required and waived positions in the regulations, summarized on the form itself, which is current as of October 2026 in its December 2022 revision.
Who must file Form 8833
You take a treaty-based return position when you maintain that a US treaty overrules or modifies a provision of the Code and so reduces, or could reduce, your tax. A treaty here includes income tax treaties, estate and gift tax treaties, and friendship, commerce and navigation treaties.
Reporting is specifically required for positions such as these:
- A nondiscrimination clause stops a Code provision from applying.
- A treaty reduces or modifies tax on gain from selling a US real property interest.
- Business income isn't attributable to a permanent establishment or fixed base in the US.
- A treaty changes the profits attributed to a US permanent establishment.
- A treaty grants a credit for a foreign tax the Code doesn't allow.
- Your residency as an individual is decided by the treaty rather than the Code.
Positions you usually don't have to report
The regulations waive reporting for several common situations. The ones individuals meet most often:
| Usually waived | Example |
|---|---|
| Treaty relief on wages, pensions, annuities and social security | A treaty limits US tax on a foreign pension |
| Treaty relief for artists, athletes, students, trainees and teachers | A visiting student claims a treaty exemption on a stipend |
| A Social Security Totalization Agreement | Avoiding double social security tax under a totalization agreement |
| Reduced withholding on FDAP income where the beneficial owner is an individual | A lower treaty rate on US dividends |
Waivers are narrow, and the IRS warns some don't apply to positions its own instructions require. If you're unsure, the cost of disclosing is a form; the cost of not disclosing a required position is the penalty.
The dual-resident trap
This is the part people underestimate. If you're a resident of both the US and another country under each country's law, and the treaty tie-breaker makes you a resident of the other country, you can claim treaty benefits as a nonresident. To do it, you file Form 1040-NR with Form 8833 attached.
But if you're a long-term resident, meaning a lawful permanent resident in at least 8 of the last 15 tax years, electing to be treated as a resident of the other country deems you to have expatriated. That can bring the exit tax under section 877A into play and means filing Form 8854. A green card holder who files Form 8833 to save tax in one year can trigger a much bigger bill.
Even after choosing treaty residence, you're still a US resident for purposes other than working out your income tax, so filings such as the FBAR can still apply.
How to fill it in
- Enter your name, US taxpayer identifying number and addresses in your country of residence and in the US.
- Check whether you're disclosing under section 6114, as a dual resident, or both.
- Line 1: the treaty country and the article you rely on.
- Line 2: the Code provision the treaty overrules or modifies.
- Line 3: the payer of the income, if it's fixed or determinable annual or periodical income such as interest, dividends, rents or wages.
- Line 4: the limitation on benefits test you meet, if the treaty has one.
- Lines 5 and 6: whether reporting is specifically required, then a brief explanation with the nature and amount of each item.
Details that trip people up
- Identifying number: an individual uses a social security number or an individual taxpayer identification number; everyone else uses an employer identification number.
- Reference ID: a foreign corporation enters any reference ID number a US person assigned to it for information reporting, for example on Form 5471 or Form 5472.
- Country address: give city, province or state, then country, and don't abbreviate the country name.
- Limitation on benefits: on line 4 you name the specific test in the treaty's LOB article that you meet. If you've asked the US competent authority for a discretionary determination and it's still pending, you generally can't claim the benefits yet.
- Related payers: a foreign person related to the payer who receives more than $500,000 in total from that payer, under a treaty with an LOB article, falls into a specifically reportable category.
The form also has a box to check if the taxpayer is a US citizen or resident or is incorporated in the US, because treaty positions aren't only for foreigners. A US company relying on a treaty, for example to claim a foreign tax credit the Code doesn't allow, discloses it on the same form.

When and where to file
Attach it to your return, for example Form 1040-NR or Form 1120-F. If you wouldn't otherwise need to file, you still file a return at the service center where you'd normally file, just to make the disclosure. You can group payments of the same type from the same payer as a single item.
The verdict
Don't assume a treaty claim speaks for itself. Check whether your position is on the required list or clearly waived, and file one Form 8833 per position when in doubt. If you hold a green card and you're thinking of using the residency tie-breaker, stop and look at the expatriation rules before you sign anything.
