You came home from a U.S. casino with a Form 1042-S, and your payout was smaller than the win because the casino withheld 30% under U.S. rules. The obvious next move seems to be your Canadian tax return. Many Canadians expect the CRA either to tax the win or to credit back what the U.S. kept. That is usually not how it works. This article explains what the CRA says about U.S. gambling winnings, why a Canadian return cannot give back U.S. tax withheld, and why any recovery of that 30% happens on a U.S. return.
Two meanings of ‘claiming’ your U.S. casino winnings
When a Canadian asks how to “claim” U.S. casino winnings, the question usually means one of two things. The first is reporting: does the win belong on the Canadian income tax return filed with the Canada Revenue Agency? The second is recovery: can any of the tax a U.S. casino held back from the payout be returned? People often treat these as one question. They are two separate questions, each with its own answer.
The two sit in different tax systems. Reporting is a Canadian matter, since the CRA decides what counts as income on a Canadian return. Recovery is a U.S. matter. The withholding was applied under U.S. law, the casino sent it to the IRS, and only the IRS can decide whether any of it comes back. A form filed with the CRA has no effect on money the IRS holds.
Keeping the two apart prevents a common mix-up. Someone learns that U.S. gambling winnings do not go on the Canadian return and assumes the matter is closed. The tax withheld at the casino is still a separate matter. The U.S. side has its own paperwork, starting with the slip the casino issued, usually a Form 1042-S.
What the CRA says about U.S. gambling winnings
The Canada Revenue Agency addresses this directly on its page Canadian residents going down south, which carries a date of 2026-01-20. Under a heading about gambling winnings, the page tells Canadian residents with U.S. lottery or gambling winnings not to report them on the Canadian income tax return, “as this income is not taxable in Canada.” That applies to winnings from a U.S. casino in the same way it applies to a U.S. lottery prize.
The CRA does not treat the winnings as income taxed somewhere else that must be reconciled. It treats them as income Canada does not tax at all. So there is no line on the T1 return for a U.S. jackpot, and no amount to convert into Canadian dollars and add to total income. A Form 1042-S from a U.S. casino is not something the Canadian return asks for.
For a Canadian resident who gambles as a pastime, reporting U.S. winnings to the CRA is not part of the process, according to the CRA page. A separate CRA rule covers people whose gambling amounts to a business, explained further down. The CRA page also says something about the tax the casino withheld, which matters for anyone hoping the Canadian return can help with the 30%.
Why the Canadian return cannot give back the U.S. tax withheld
The same CRA page goes one step further. After saying U.S. gambling winnings stay off the Canadian return, it says no credit can be claimed for the taxes withheld on them. The amount the casino held back, shown on your Form 1042-S, has no place on your T1 return. No line, schedule or credit on the Canadian side picks it up.
The reason sits in how Canada’s foreign tax credit works. The credit exists to prevent double taxation, and it is always measured against Canadian tax owed on the same income. U.S. gambling winnings carry no Canadian tax, because the CRA treats them as not taxable. With no Canadian tax to reduce, there is nothing for a credit to apply against.
There is also a simpler point. The withheld amount was paid to the IRS, not to the CRA, and the CRA cannot refund money it never received. Filing a T1, adjusting a past return or calling the CRA does not change where that money is held. Only the U.S. system can return any part of it, through a U.S. return that the IRS reviews and decides on its own terms. For background, see how U.S. casino winnings are taxed and how refunds work.
The narrow exception: gambling as a business
The CRA’s position has one narrow carve-out, explained in Income Tax Folio S3-F9-C1. Paragraph 1.12 says gambling can produce taxable income only if the activity amounts to carrying on the business of gambling. In that case the gains are business income. The question is whether the activity is a business. Playing often, or winning a large amount, does not answer that by itself.
Paragraph 1.13 sets the bar high. It says that even gambling that is regular, frequent and systematic is not generally treated as a commercial activity, and it limits business treatment to very exceptional circumstances. So a Canadian who visits U.S. casinos several times a year, keeps detailed records and plays to a personal system is, on the CRA’s stated approach, still usually a recreational gambler. Frequency and discipline describe a habit. They do not turn it into a business.
For most readers, the exception does not change anything. The winnings stay off the Canadian return and no credit is claimed there for the U.S. tax withheld. Someone whose facts might fit the exception is dealing with a question that turns on their own circumstances.
Where the 30% came from and the slip that shows it
The amount the casino held back comes from U.S. law, not Canadian law. IRS Publication 515, the IRS guide to withholding on nonresident aliens and foreign entities, describes the rule. Gambling winnings that a nonresident alien wins in the United States are subject to withholding at 30% under chapter 3 of the Internal Revenue Code. The rate applies to the gross proceeds of the win. The casino takes 30% of the full payout and does not subtract any earlier losses first.
Publication 515 names situations where that withholding does not apply, including income effectively connected with a U.S. trade or business and income exempted by a tax treaty. The cashier paying out a jackpot cannot weigh these questions. When neither exception has been established at the time of payment, the casino withholds 30% of the full amount, and any correction has to happen afterward on a U.S. return.
The casino then reports the payment on Form 1042-S, the slip used for U.S.-source income paid to foreign persons. It shows the gross income paid, an income code that marks the payment as gambling winnings, and the federal tax withheld. Some winners receive a W-2G instead, so it helps to confirm which slip you received.
The IRS already has a copy of the 1042-S, because the casino files it as well as sending it to you. Any later return claims back tax that this slip says was withheld, so the figures on the return have to match the slip. For a closer look, see what Form 1042-S shows in our 1042-S guide.
Why any recovery happens on a U.S. return
The U.S. nonresident return is the part of the U.S. tax system that handles U.S.-source income not connected with a U.S. trade or business. Casino winnings for a visitor who does not gamble for a living land there. The tax calculated on that return is compared against the amount the casino already sent to the IRS, as shown on Form 1042-S. Nothing on the Canadian side performs that comparison, which is why a U.S. return is the only place the withholding can be revisited.
For a Canadian resident who is not in the business of gambling, gambling winnings are reported there, but winnings from blackjack, baccarat, craps, roulette and the big-6 wheel are left off, because they are not taxed for nonresident aliens. The reasons table games are treated differently from slots are covered in why blackjack and table games aren’t withheld like slots.
This is also where the tax treaty between Canada and the U.S. shows up. A resident of Canada not in the business of gambling may deduct gambling losses incurred in the United States, but only up to the amount of U.S.-source gambling winnings. Losses from casinos in Canada or elsewhere do not count. The losses need support, which is usually a casino win-loss statement. The treaty language is explained in how the treaty treats your gambling losses.
The cap has a direct consequence. If your U.S. losses for the year exceed your U.S. winnings, no net gambling loss is allowed. The deduction stops at zero and nothing carries over to reduce other income. When the withholding is larger than the tax calculated, the return shows an overpayment. The IRS reviews the return and decides what, if anything, is refunded.
Canadian return vs. U.S. return, side by side
The table below lines up the two returns against the same four questions. It rests only on the CRA page Canadian residents going down south, CRA Income Tax Folio S3-F9-C1, IRS Publication 515 and the IRS instructions for nonresident returns. The pattern is simple. The Canadian return leaves U.S. casino winnings out entirely. The U.S. nonresident return is the only one of the two that has a place for the winnings, the tax withheld and the losses.
| Question | Canadian return (CRA) | U.S. return (nonresident) |
|---|---|---|
| Are U.S. casino winnings reported? | No. The CRA says U.S. lottery or gambling winnings are not reported because the income is not taxable in Canada. | Yes. Gambling winnings are reported. Blackjack, baccarat, craps, roulette and big-6 wheel winnings are excluded. |
| Which document shows the winnings and tax withheld? | None is used. The winnings do not appear on the Canadian return. | Form 1042-S, which reports the gross winnings and the 30% chapter 3 withholding described in Publication 515. |
| Can the U.S. tax withheld be credited or refunded? | No. The CRA says no credit can be claimed for taxes withheld on these winnings. | The withholding counts as a payment. Any amount above the tax figured is an overpayment, and the IRS decides each return. |
| Where do gambling losses come in? | Nowhere, unless gambling amounts to carrying on a business (Folio S3-F9-C1, paragraphs 1.12 and 1.13). | U.S.-source losses can be deducted up to U.S.-source winnings. A net gambling loss cannot be deducted. |
What a U.S. claim involves
A U.S. claim is built from a short stack of documents:
- Form 1042-S, the slip from the casino showing gross winnings and the U.S. tax withheld
- the casino win-loss statement, which records U.S.-source wins and losses for the year
- an ITIN, either an existing number or a new application
Each document has a specific job. The 1042-S supplies the winnings and the amount withheld. The win-loss statement supports the losses, up to the amount of U.S.-source winnings. The ITIN is needed because the IRS requires a taxpayer identification number to process a return. The ITIN page explains who needs one. U.S. Tax Recovery prepares and files the return for you.
U.S. Tax Recovery is an IRS Certifying Acceptance Agent, listed on the IRS’s Acceptance Agents directory for Canada. That credential lets it certify identity documents for an ITIN application. It is not affiliated with the IRS. The IRS decides each return and sets the pace, which varies from case to case. Time limits for a refund claim depend on the tax year and are checked case by case. A fuller list sits in what documents a claim needs.
Frequently Asked Questions
Do I have to report my U.S. casino winnings on my Canadian tax return?
For most people, no. The CRA generally treats casual gambling winnings as windfalls rather than income, so a recreational player does not include them on a Canadian return. The exception is gambling organized like a business. There, the CRA looks at facts such as skill, frequency and whether the activity is a livelihood, and winnings can become business income.
Can I get the 30% back by claiming a foreign tax credit in Canada?
Usually not. A foreign tax credit only offsets Canadian tax owed on the same income, and casual gambling winnings normally carry no Canadian tax. With nothing to offset, the U.S. tax has no place on the Canadian return. The 30% was withheld under U.S. rules and sent to the IRS, so any refund request is made on a U.S. return.
What document shows how much tax the casino kept?
Form 1042-S, which U.S. casinos issue to non-resident winners. It reports gross winnings, an income code identifying the payment as gambling winnings, and the federal tax withheld. A W-2G goes to U.S. persons instead. A U.S. claim relies on the 1042-S along with records of gambling losses from the same year.
How does the tax treaty between Canada and the U.S. help with getting the tax back?
The treaty lets a Canadian resident deduct U.S. gambling losses against U.S. gambling winnings from the same tax year, which most non-residents cannot do. Losses can reduce winnings to zero but cannot create an overall loss. If that lowers the tax owed below the amount withheld, the IRS decides whether to refund the difference.
I don’t have a Social Security number. Can I still file a U.S. return?
Yes, through an ITIN. A U.S. return requires a taxpayer identification number, and a Canadian without U.S. work history usually has neither an SSN nor an ITIN. U.S. Tax Recovery is an IRS Certifying Acceptance Agent, listed on the IRS’s Acceptance Agents directory for Canada, and handles the ITIN application for you.
