Treaty-Based Return Position Disclosure
Form 8833: When You Must Disclose a Tax Treaty Position
When a tax treaty changes what the Internal Revenue Code would otherwise tax, the IRS usually wants to be told. Form 8833 is how. It applies to foreign owners of US businesses, people resident in two countries and US taxpayers relying on a treaty, and leaving it out has its own penalty.
Quick answer
When do you need to file Form 8833?
When you take a treaty-based return position: you maintain that a US treaty overrides or modifies the Internal Revenue Code and reduces your tax. A separate Form 8833 is attached to the return for each position, unless the regulations waive reporting. Failing to disclose can cost US$1,000, or US$10,000 for a C corporation (IRS).

Who must file
Generally anyone who takes a treaty-based return position, meaning they maintain that a US treaty overrules or modifies a provision of the Internal Revenue Code and so reduces tax on their return. A treaty here includes income tax treaties, estate and gift tax treaties and friendship, commerce and navigation treaties (IRS). The list of US income tax treaties is on the IRS treaty page.
Positions the IRS specifically lists
This is not the full list, and some of these are waived in certain cases.
No US permanent establishment
Business profits that are effectively connected with a US trade or business but not attributable to a US permanent establishment. Common for foreign owners of US companies; see US LLC tax by country.
US real property
A treaty reducing or modifying US tax on gain or loss from selling a US real property interest.
Branch profits tax
A treaty reducing or modifying the branch profits tax or the tax on excess interest.
Nondiscrimination
A treaty nondiscrimination article preventing a Code provision from applying.
Business profits amounts
A treaty changing the amount of business profits attributable to a US permanent establishment.
Foreign tax credits and source
A treaty allowing a foreign tax credit the Code does not, or changing the source of income or deductions for a non-individual.
Dual residents
If you are a resident of both the US and another country under each country's law, and the treaty's tie-breaker rule makes you a resident of the other country, you can claim treaty benefits as a nonresident of the US by filing Form 8833 (IRS). Two cautions:
- A long-term green card holder who claims treaty residence abroad this way may be treated as having expatriated under section 877A, with exit tax rules to consider. See Form 8854 and exit tax.
- US citizens generally cannot use a treaty to cut their own US tax because of the saving clause (IRS Pub 519).
The penalty, and when reporting is waived
Failing to disclose a treaty-based return position may result in a penalty of US$1,000 for each failure, or US$10,000 for a C corporation, under section 6712 (IRS).
Some positions are waived from reporting under Regulations section 301.6114-1(c), for example certain reduced withholding rates that are already properly reported. The waivers are narrow and do not cover the positions the instructions specifically require, so we check the regulation for each case.

Common questions
What is a treaty-based return position?
Maintaining on a return that a US treaty overrules or modifies a provision of the Internal Revenue Code and causes, or may cause, a reduction of tax.
What is the penalty for not filing Form 8833?
US$1,000 for each failure to disclose, or US$10,000 for a C corporation, under section 6712.
Do I file one Form 8833 for all my treaty positions?
No. A separate Form 8833 is required for each treaty-based return position, although payments of the same type from the same payer can be treated as one item.
Can a US citizen use Form 8833 to reduce US tax?
Rarely. Treaties have a saving clause that lets the US tax its citizens as if there were no treaty, apart from listed exceptions.
