How the Canada at U.S. Tax Treaty Gambling Losses Benefit Works
The Canada at U.S. tax treaty gambling losses benefit comes from Article XXII(3) of the Canada at U.S. Tax Treaty. It allows Canadian residents to deduct documented gambling losses against their U.S. gambling winnings from the same year at something most non-residents from other countries cannot do. Without this provision, the full 30% withheld by the casino would be the baseline tax owed. With it, your actual taxable amount can be significantly lower, and your refund correspondingly larger.
At U.S. Tax Recovery, we apply this treaty benefit on behalf of our Canadian clients when we prepare and file their U.S. non-resident returns. Claiming it correctly requires citing the right article, matching figures to your Form 1042-S, and filing a complete Form 1040-NR at none of which happens automatically.
KEY TAKEAWAYS
- Article XXII(3) of the Canada at U.S. Tax Treaty lets Canadian residents offset U.S. gambling losses against U.S. gambling winnings in the same year.
- This benefit is never applied automatically at you must file a Form 1040-NR and cite the treaty article correctly.
- Canadians are not exempt from U.S. gambling tax; the treaty reduces what is owed, it does not eliminate the obligation to file.
- Documented losses from the same U.S. trip are required at undocumented losses cannot be claimed.
What Does Article XXII(3) Actually Say?
Article XXII(3) of the Canada at U.S. Tax Treaty is the specific provision that governs gambling income. It grants Canadian residents the same treatment as U.S. residents when it comes to offsetting gambling losses at meaning losses can be deducted against winnings, but only up to the amount of those winnings. You cannot use gambling losses to create a net negative income figure; the floor is zero.
This matters because U.S. tax law treats gambling winnings paid to non-resident aliens differently from those paid to U.S. residents. Without a treaty provision, a non-resident’s winnings are taxed at the flat 30% withholding rate with no deduction for losses at all. Article XXII(3) carves out an exception specifically for Canadians, and it is the reason a meaningful refund is possible for most of our clients.
Which Winnings Does the 30% Withholding Apply To?
Not every win at a U.S. casino triggers withholding. The IRS applies the 30% rate when payouts cross specific thresholds by game type. Understanding these thresholds helps you know which wins will appear on a Form 1042-S and therefore which ones require a refund claim.
| Game Type | Withholding Threshold |
|---|---|
| Slot machines | $1,200 or more from a single jackpot |
| Keno | $1,500 or more |
| Poker tournaments | More than $5,000 |
| Blackjack, baccarat, craps, roulette | Generally no automatic withholding |
When a win crosses the applicable threshold, the casino issues a Form 1042-S documenting the gross amount and the tax withheld. That form is the starting point for your refund claim. You can read more about what Form 1042-S shows and how to use it in our dedicated guide.
What Counts as a Deductible Gambling Loss?
Under Article XXII(3), the losses you can claim are those incurred from U.S. gambling activity in the same tax year as your winnings. Losses from Canadian casinos do not qualify. Losses from a different tax year do not carry forward or back.
How to Document Your Losses
The IRS does not accept a self-reported number. You need documentation. The most common and accepted sources are:
- A win-loss statement from the casino, covering the full tax year
- Player rewards card records showing your tracked activity
- Records of travel dates to the United States, to confirm the activity occurred in the same year
Large U.S. casinos can typically provide a win-loss statement on request. The statement shows your net activity across all tracked play at that property for the year. If you played at multiple casinos, you will need a statement from each one.
What If You Did Not Use a Player’s Card?
Untracked play is harder to document. Without a player’s card, the casino has no record of your session activity, and a win-loss statement will not reflect it. In that situation, the documented losses available to you may be lower at or absent entirely at which limits the treaty benefit you can claim. This is one of the practical reasons regular U.S. casino visitors benefit from using a player’s rewards card consistently.
Why the Treaty Benefit Does Not Apply Automatically
The casino withholds 30% at the time of your win and remits it to the IRS. That transaction is complete before you leave the building. The IRS does not review your losses or apply any treaty adjustment at that stage. The 30% is simply held.
To recover some or all of that withheld amount, you must file Form 1040-NR at the U.S. Non-Resident Alien Income Tax Return. On that return, you cite Article XXII(3) of the Canada at U.S. Tax Treaty, report your gross winnings, and apply your documented losses to calculate the actual tax owed. The difference between what was withheld and what you owe is your refund.
An error in the treaty citation, a mismatch between the figures on your return and your Form 1042-S, or a missing certification can cause the IRS to reject the return or issue a notice requesting additional information. That is why filing this return correctly the first time matters. You can learn more about how Form 1040-NR works for Canadian casino winners in our filing guide.
One Reason to File With a Specialist
The treaty article must be cited correctly on the return. The loss amount must be supported by documentation the IRS will accept. The figures must reconcile precisely with the Form 1042-S the casino filed. A valid ITIN must be on the return before the IRS will process it.

Frequently Asked Questions
Are Canadians exempt from U.S. gambling tax under the treaty?
No. The treaty does not exempt Canadians from U.S. gambling tax. What Article XXII(3) does is allow Canadian residents to deduct documented gambling losses against their winnings in the same year, which can reduce the taxable amount and generate a refund of some or all of the withheld tax. Exemption and a loss offset are not the same thing.
Can I claim losses from a different year against this year’s winnings?
No. The treaty benefit applies only to losses incurred in the same tax year as the winnings. Losses from a prior or subsequent year cannot be carried back or forward to offset a different year’s winnings. Each tax year is filed separately, and the loss offset is calculated within that year only.
What if my losses exceed my winnings?
Under Article XXII(3), losses can only offset winnings at they cannot create a net negative gambling income figure. If your documented losses exceed your winnings for the year, the taxable amount is reduced to zero and you would be entitled to a full refund of the withheld tax. The excess losses do not carry over or generate any additional benefit.
Had U.S. Tax Withheld? The Treaty Benefit May Help.
