Treaty positions documented — not hoped for
The US–Canada tax treaty assigns taxing rights between the two countries — but a treaty position that isn’t disclosed on Form 8833 is a position you’re hoping nobody asks about. We put the position, the treaty article, and the facts on the record, properly, the year you take it.

The disclosure that makes a treaty claim real
Form 8833 — the Treaty-Based Return Position Disclosure under IRC §6114 — is how you tell the IRS, on the return itself, that a treaty provision changes the tax the Code would otherwise impose: which article, which income, and why the facts qualify.
Not every treaty claim requires it — the regulations waive disclosure for a list of routine items — but for the positions that do (residency tie-breakers chief among them), failure to disclose carries a penalty of $1,000 per failure ($10,000 for corporations), and leaves the position undocumented exactly where documentation matters most: on the record, before anyone asks.
The US–Canada treaty claims we document most
Residency tie-breaker — Article IV
Resident of both countries under domestic rules? The treaty assigns you to one. Claiming it on a US return is a required 8833 disclosure — and the facts behind it need to hold up.
RRSP and pension benefits
The treaty preserves the RRSP/RRIF deferral for US residents and coordinates cross-border pension income. The positions are routine; the paperwork behind them isn’t optional.
Reduced withholding — dividends, interest, royalties
Treaty rates cut the default 30% US withholding, often dramatically. Claimed at the payer with the right forms, reconciled on the return — and disclosed where the rules require it.
Employment income exemptions — Article XV
Short, modest work stints in the other country can stay taxable only at home — under conditions on days, dollars, and who bears the cost. A position worth documenting the day it’s taken.
Capital gains sourcing — Article XIII
The treaty decides which country may tax which gains — and pointedly leaves real estate taxable where it sits. Getting the sourcing right decides where the tax and the credit land.
Snowbirds — closer connection and Form 8840
The 8840 keeps qualifying snowbirds out of US residency without the treaty; past 183 actual days, the treaty tie-breaker takes over. The snowbird package manages both doors.
The deep-dive behind “treaty positions documented”
Our cross-border practice promises treaty positions documented, not assumed — this page is what that means in practice. A treaty benefit claimed silently is fragile: the facts fade, the preparer changes, and years later someone reconstructs why a return was filed the way it was. A position disclosed on Form 8833 — article cited, facts stated — is the opposite: it starts the statute running, survives an examination on its own paper, and travels intact between the US and Canadian sides of your file. The same discipline pays again when residency changes: a treaty-based exit from one system interacts directly with Canada’s departure tax, and the positions have to line up on both returns.

Treaty questions, answered straight
When is Form 8833 required?
Whenever you take a return position that a US–Canada treaty provision overrides or modifies the tax the Internal Revenue Code would otherwise impose — unless the regulations specifically waive disclosure for that item. Residency tie-breakers and certain pension positions are classic must-file situations; some routine withholding-rate claims are waived. Which side of that line your position sits on is exactly what we determine before filing.
What’s the penalty for not filing it?
For a required disclosure that isn’t made: $1,000 per failure for individuals, $10,000 for corporations — per position, per year. And the money is the smaller problem: an undisclosed position is far weaker if the IRS examines the return, because you’re explaining after the fact instead of on the record.
Doesn’t the treaty stop double taxation automatically?
No. The treaty is a rulebook, not a mechanism — it assigns taxing rights and provides relief, but only through positions actually claimed on returns: an election here, a disclosure there, foreign tax credits computed to match. Two returns filed without coordinated treaty positions can absolutely double-tax the same income.
Can I be a tax resident of both countries?
Under each country’s domestic rules, yes — easily. The treaty’s Article IV tie-breaker then assigns you to one country through a cascade of tests (permanent home, centre of vital interests, habitual abode, citizenship). Claiming the tie-breaker on the US side is a textbook Form 8833 disclosure, and on the Canadian side it can trigger departure-tax consequences worth pricing first — see our departure tax planning service.
Do snowbirds need Form 8833?
Usually not — a snowbird who meets the closer connection exception files Form 8840 instead, which keeps them out of US residency without invoking the treaty. Form 8833 enters the picture when the 8840 route closes (183+ actual days in the year) and the treaty tie-breaker becomes the fallback. Our snowbird package on the cross-border page watches exactly that line.
