What a Casino Win-Loss Statement Does on a U.S. Tax Return
A casino win-loss statement is the document that supports the gambling loss deduction on your U.S. tax return as a Canadian non-resident. Without it, the IRS has no basis to accept a loss offset against your winnings — and without that offset, you may owe more than you should, or receive a smaller refund than you are entitled to.
At U.S. Tax Recovery, we use win-loss statements as a core part of every 1040-NR refund claim we file for our Canadian clients. Getting this document right — and using it correctly — directly affects how much of the withheld 30% you can recover.
KEY TAKEAWAYS
- A casino win-loss statement documents your tracked gambling activity for a full tax year at a specific property.
- Canadians need it to claim the Article XXII(3) loss offset under the Canada–U.S. Tax Treaty on Form 1040-NR.
- Only losses from U.S. gambling activity in the same tax year as your winnings can be applied against those winnings.
- Untracked play — sessions without a player’s card — will not appear on the statement and cannot be claimed.
What Is a Casino Win-Loss Statement?
A win-loss statement is a summary report that a U.S. casino produces from its player rewards system. It shows your total tracked wins and total tracked losses at that property over a specified period — typically a full calendar year. The casino generates it from your player’s card activity, which records every session you play on tracked machines or tables.
The statement is not a tax form. The casino does not file it with the IRS. It is a supporting document that you attach to your Form 1040-NR to substantiate the gambling losses you are claiming under the Canada–U.S. Tax Treaty.
Why Canadians Need It to Claim the Treaty Benefit
Article XXII(3) of the Canada–U.S. Tax Treaty allows Canadian residents to deduct documented gambling losses against their U.S. gambling winnings from the same tax year. This provision is the reason a meaningful refund is possible for most of our clients — it can reduce the taxable amount significantly, and in some cases bring it to zero.
The operative word is documented. The IRS does not accept a self-reported loss figure. You need a record that an independent source — the casino — has produced. A win-loss statement is the most commonly accepted form of that documentation. Without it, the treaty benefit cannot be applied, and the full 30% withheld by the casino remains the basis for calculating what you owe.
You can read more about how this treaty provision works in our guide to Canada–U.S. Tax Treaty gambling benefits for Canadians.
How to Request a Win-Loss Statement From a U.S. Casino
Most large U.S. casinos can provide a win-loss statement on request. The process varies by property, but these steps apply at most major casinos:
- Contact the casino’s player rewards desk, tax department, or guest services by phone or in writing.
- Provide your player’s card number and the tax year you need the statement for.
- Request a statement that covers the full calendar year, not just the date of your jackpot win.
- Ask for the statement to be issued on casino letterhead, as the IRS expects a formal document.
Some casinos allow you to download a win-loss statement through their online rewards portal. Others require a written request or an in-person visit. Allow enough time — particularly if you are approaching the three-year refund claim window — because some properties take several weeks to process requests.
What If You Played at Multiple Casinos?
If you visited more than one U.S. casino in the same tax year, you need a separate win-loss statement from each property. All of your U.S. gambling activity for the year is reported on a single Form 1040-NR, and the combined losses from all properties are applied against your combined winnings. A statement from only one casino will not capture the full picture of your losses for the year.
What If You Did Not Use a Player’s Card?
If you played without a rewards card, the casino has no record of your session activity. A win-loss statement will not reflect untracked play, which means those losses are effectively invisible for tax purposes. This is one of the most practical reasons to use a player’s card consistently when visiting U.S. casinos — not for the rewards, but for the documentation it creates.
Untracked losses are difficult or impossible to substantiate to the IRS’s standard. In that situation, the treaty offset may be limited or unavailable, and the refund you can recover will be smaller than it might otherwise be.
How the Win-Loss Statement Fits Into the 1040-NR Filing
The win-loss statement does not stand alone. It works alongside your Form 1042-S, which the casino issues to document the specific jackpot that triggered withholding. Together, these two documents form the core of your refund claim.
| Document | What It Shows | Role in the Claim |
|---|---|---|
| Form 1042-S | Gross winnings and amount withheld by the casino | Establishes the withholding to be refunded |
| Win-loss statement | Total tracked wins and losses for the full year | Supports the Article XXII(3) loss deduction |
| Travel records | Dates of U.S. visits in the tax year | Confirms losses occurred in the same year as winnings |
| Form 1040-NR | The U.S. non-resident return itself | The filing that claims the refund |
The figures on your 1040-NR must reconcile precisely with your Form 1042-S. The loss amount you claim must be supported by the win-loss statement. A mismatch between any of these documents can result in the IRS holding your return for review or requesting additional information — which adds months to the timeline.
One Reason to File With a Specialist Rather Than Alone
Applying a win-loss statement correctly on a Form 1040-NR requires more than attaching it to the return. The loss amount must be calculated within the limits Article XXII(3) permits — losses can offset winnings, but they cannot create a net negative gambling income figure. The treaty article must be cited precisely. The figures must reconcile with the 1042-S. And a valid ITIN must be on the return before the IRS will process it.
Our team handles these filings regularly and knows exactly what the IRS expects at each step. As an IRS Certified Acceptance Agent, we also verify your passport in our office — so you never have to mail your original passport to the IRS and wait weeks without it. You can review our complete refund process from start to finish to see how each piece fits together.
The Three-Year Window and Why Acting Early Matters
The refund claim window is generally three years from the original filing deadline for the tax year in which your winnings were withheld. If you have a Form 1042-S from a prior year and have not yet filed, the first step is to request your win-loss statement from the casino — because that process takes time, and so does IRS processing once the return is filed.
IRS processing of non-resident gambling refund returns typically takes many months from the date the IRS receives a complete, correctly prepared return. Filing close to the three-year deadline leaves no margin for errors or IRS correspondence.

Frequently Asked Questions
Can I use a win-loss statement from a Canadian casino on my U.S. return?
No. Article XXII(3) of the Canada–U.S. Tax Treaty only allows losses from U.S. gambling activity to be offset against U.S. gambling winnings. Losses incurred at Canadian casinos, even in the same tax year, do not qualify. Only activity at U.S. properties — documented by a U.S. casino win-loss statement — can be applied to reduce your taxable U.S. gambling income.
What if my win-loss statement shows a net win for the year?
If your total tracked wins exceed your total tracked losses for the year, the statement will show a net win rather than a net loss. In that case, the loss offset under Article XXII(3) is limited to the amount of your losses — you cannot use it to reduce your taxable winnings below zero. The refund you may be entitled to will be smaller, but filing is still worthwhile to recover whatever portion of the withheld tax exceeds the actual tax owed.
How far back can I request a win-loss statement from a casino?
Most large U.S. casinos retain player activity records for several years, so requesting a statement for a prior tax year is generally possible. Contact the casino’s tax or rewards department directly. If the casino cannot locate your records, you may still be able to support a partial claim with other documentation, though the process becomes more complex. Act as early as possible to give yourself time to resolve any gaps before the refund window closes.
