What Article XXII(3) of the Canada at U.S. Tax Treaty Actually Says About Gambling Losses
Canada at U.S. tax treaty gambling losses are governed by one specific paragraph: Article XXII(3). It allows Canadian residents to deduct documented U.S. gambling losses against their U.S. gambling winnings in the same tax year at reducing, and sometimes eliminating, the tax they actually owe. This is not a full exemption from U.S. gambling tax. It is a loss-offset right, and it only applies when you claim it correctly on a filed return.
At U.S. Tax Recovery, we apply this treaty provision on behalf of our Canadian clients when we prepare and file their IRS Form 1040-NR refund claims. Getting the article cited precisely, and the losses documented properly, is what determines how much of the withheld 30% you can recover.
KEY TAKEAWAYS
- Article XXII(3) of the Canada at U.S. Tax Treaty lets Canadians offset documented U.S. gambling losses against U.S. gambling winnings from the same tax year.
- Canadians are not exempt from U.S. gambling tax at the treaty reduces what you owe, it does not eliminate the obligation to file.
- Losses must come from U.S. gambling activity in the same calendar year as the winnings at Canadian casino losses do not qualify.
- The treaty benefit is never applied automatically at it must be cited correctly on Form 1040-NR with supporting documentation.
Why Canada’s Treaty Provision Is Different From Every Other Country’s
Most countries that have a tax treaty with the United States do not have any specific language addressing gambling income. Their residents recover withheld casino tax at if at all at through general nonresident filing procedures, with no treaty shortcut for losses.
Canada’s treaty is different. Article XXII(3) explicitly grants Canadian residents the same loss-deduction treatment that U.S. residents receive when it comes to gambling. That means a Canadian who lost money at U.S. casinos in the same year they had a jackpot withheld can apply those losses to reduce their taxable winnings at just as a U.S. resident would on a domestic return. No other country’s treaty with the United States includes this specific gambling carve-out in the same way.
This is the legal foundation behind most Canadian casino tax refund claims. Without it, Canadians would owe tax on the full gross winnings, with no way to account for losses from the same trip or year.
What Losses Qualify Under Article XXII(3)?
Only losses from U.S. gambling activity in the same tax year as your winnings can be applied. The rules are specific, and understanding them before you file prevents mistakes that reduce your refund.
What counts
- Losses at U.S. casinos during the same calendar year as the jackpot that was withheld
- Losses from any type of U.S. gambling at slots, table games, poker, keno, bingo at as long as they are documented
- Losses from multiple U.S. properties in the same year, each supported by a win-loss statement from that property
What does not count
- Losses at Canadian casinos at the treaty only covers U.S.-source gambling activity
- Losses from a different tax year at you cannot carry losses forward or backward to match a different year’s winnings
- Untracked losses at sessions played without a player’s rewards card produce no casino record and generally cannot be substantiated
- Self-reported figures without independent documentation at the IRS does not accept your own estimate
One important limit: losses can reduce your taxable gambling income to zero, but they cannot create a net negative figure. Article XXII(3) allows an offset, not a deduction that generates a refund beyond what was withheld.
How the Loss Offset Changes Your Refund Amount
The 30% the casino withheld is based on your gross winnings at not your net result for the year. Article XXII(3) lets you recalculate what you actually owe based on net winnings after losses, and the difference between what was withheld and what you actually owe is what comes back as a refund.
| Scenario | Without Treaty Offset | With Article XXII(3) |
|---|---|---|
| Gross slot winnings | Taxed at 30% | Losses subtracted first |
| Documented U.S. losses same year | Not considered | Applied against winnings |
| Taxable amount | Full gross winnings | Net winnings (or zero) |
| Refund potential | Little or none | Some or all of the 30% withheld |
The size of the refund depends entirely on how well your losses are documented. A thorough win-loss statement from every U.S. casino you visited that year is the most accepted form of evidence. Our guide on using a casino win-loss statement on your U.S. return explains how to request one and what the IRS expects to see.
Why the Treaty Benefit Is Never Applied Automatically
The casino does not apply Article XXII(3) at the cage. It withholds 30% of your gross winnings and issues you a Form 1042-S at that is all it is required to do. The treaty offset only comes into play when you file IRS Form 1040-NR, cite the article precisely, and attach the supporting documentation.
If you never file, the IRS keeps the withheld amount. There is no automatic review, no refund issued without a claim, and no mechanism that applies the treaty on your behalf. The refund claim window is generally three years from the original filing deadline for the tax year in question. After that, the withheld amount stays with the IRS permanently.
One practical reason to work with our team rather than file alone: the treaty article must be cited correctly, the figures on your return must match your Form 1042-S exactly, and the loss documentation must be applied within the limits Article XXII(3) permits. A missing citation or a mismatched figure can result in months of additional IRS processing or a return held for review.

What You Need Before You Can Claim the Treaty Offset
Filing a 1040-NR that correctly applies Article XXII(3) requires several documents to be in order before the return is prepared.
- Form 1042-S at issued by the casino documenting your gross winnings and the 30% withheld. Every 1042-S from every U.S. property in the same tax year must be included.
- Win-loss statement at from each U.S. casino you visited in the same year, covering the full calendar year, issued on casino letterhead. This is the primary evidence for your loss deduction.
- A valid ITIN at the IRS requires an Individual Taxpayer Identification Number on every return it processes. Canadians are not eligible for a U.S. Social Security Number, so an ITIN obtained through Form W-7 is required. If you have an existing ITIN, confirm it has not been deactivated due to three consecutive years without use.
- Proof of Canadian residency at to establish your eligibility under the Canada at U.S. treaty.

Frequently Asked Questions
Can I use losses from a Canadian casino to offset my U.S. winnings under Article XXII(3)?
No. Article XXII(3) of the Canada at U.S. Tax Treaty only permits the deduction of U.S. gambling losses against U.S. gambling winnings. Losses incurred at Canadian casinos, even in the same tax year, do not qualify. The loss must originate from U.S.-source gambling activity and must be documented by a U.S. casino win-loss statement.
What if my documented losses are larger than my winnings?
Article XXII(3) allows losses to reduce your taxable gambling income to zero, but not below. If your documented U.S. losses for the year exceed your U.S. winnings, your taxable amount is zero and a full refund of the withheld tax may be possible at but the excess losses do not generate an additional refund or carry over to another year.
Does Article XXII(3) apply to all types of U.S. gambling winnings?
Yes. The treaty provision covers U.S. gambling income broadly at slots, table games, poker tournaments, keno, and bingo. The type of game does not change your eligibility to apply the loss offset. What matters is that both the winnings and the losses occurred at U.S. venues in the same tax year and are properly documented.
