Form 8833: Disclosing a Treaty-Based Return Position
When a treaty position must be disclosed, the common Canadian positions, the exceptions, and the penalties
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Form 8833 is the disclosure attached to a U.S. return when a taxpayer takes a position that a tax treaty overrides U.S. law. For Canadians, the common positions are the residency tie-breaker, business profits with no U.S. permanent establishment, and the post-move basis election. An undisclosed position costs US$1,000 for individuals and US$10,000 for corporations.

Common Canada–U.S. positions
| Position | Treaty article | Typical filer |
|---|---|---|
| Treaty tie-breaker — resident of Canada despite meeting the U.S. residency tests | Article IV | Snowbird over 183 days; green card holder living in Canada |
| Business profits not taxable — no U.S. permanent establishment | Articles V and VII | Canadian corporation with U.S. activity filing a protective Form 1120-F |
| Basis step-up election on property after a move to the U.S. | Article XIII(7) | New U.S. resident who paid Canadian departure tax |
| Reduced rate or exemption on certain income not covered by withholding forms | Various | Individuals and corporations claiming treaty rates on their returns |
| Self-employed services income exempt — no U.S. permanent establishment | Articles V and VII | Canadian consultant working on U.S. projects |
When it isn't required
Disclosure isn't required for reduced withholding rates claimed with the payer on a W-8BEN or W-8BEN-E (on dividends, interest, royalties) where the income is properly reported, for the Article XVIII(7) deferral of RRSP and RRIF income (automatic for eligible individuals under Rev. Proc. 2014-55, with no election statement), for positions on wages, pensions, annuities, and Social Security, and for an individual whose treaty-affected payments total no more than US$10,000 for the year (Treas. Reg. 301.6114-1(c)) — though the tie-breaker claim still needs Form 8833.
The green card holder's warning
A green card holder who uses the treaty tie-breaker to be treated as a Canadian resident (and notifies the IRS, which Form 8833 does) stops being a lawful permanent resident for tax purposes; one who has held the card in at least 8 of the last 15 tax years is treated as having expatriated on that date (sections 7701(b)(6) and 877A(g)(2)) — which can trigger the expatriation tax (the expatriation tax guide). The tie-breaker is not a neutral form for a green card holder.
Penalties
US$1,000 per failure for individuals, US$10,000 for C corporations (section 6712), waivable for reasonable cause and good faith. Failing to disclose doesn't itself forfeit the treaty benefit — the penalty is the consequence.
Frequently asked questions
When do I need Form 8833?
When your return takes a position that a treaty overrides U.S. tax law — such as claiming Canadian residency under the tie-breaker or excluding business profits because you have no U.S. permanent establishment.
Do I need Form 8833 for my RRSP?
Generally not — the RRSP's U.S. tax deferral applies automatically for eligible individuals (Rev. Proc. 2014-55), and pension positions are exempt from disclosure.
What is the penalty for not filing Form 8833?
US$1,000 per undisclosed position for individuals, US$10,000 for corporations.
Can a green card holder use the tie-breaker?
Yes, but for a long-term resident (card held in 8 of the last 15 years) it counts as expatriating — with possible exit tax consequences.

The IRS explains: “Taxpayers use this form to make the treaty-based return position disclosure required by Internal Revenue Code section 6114. Dual-resident taxpayers use this form to make the treaty-based return position disclosure required by Regulations section 301.7701(b)-7.” — Internal Revenue Service, About Form 8833, Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b), https://www.irs.gov/forms-pubs/about-form-8833
IRS Publication 597 states: “If you are a U.S. citizen or green card holder living in Canada, you still have to file a Form 1040 and report your worldwide income because of the 'saving clause' in Article XXIX(2), which allows the United States to tax its citizens and residents as if the treaty had not entered into effect.” — Internal Revenue Service, Publication 597 (10/2015), Information on the United States–Canada Income Tax Treaty, https://www.irs.gov/publications/p597
