How we estimate your refund
-
The casino kept 30%
A 30% federal withholding rate may apply to certain gambling winnings paid to non-U.S. residents. It’s shown on your slip, usually a Form 1042-S.
-
Your losses can lower the tax
Eligible Canadian residents may deduct qualifying U.S. gambling losses, subject to tax-year restrictions.
-
You may get the difference back
If the casino kept more than you owe, we claim the difference back for you.
An example (2025 or earlier)
| Won at a U.S. casino | $10,000 |
|---|---|
| Held back at 30% | $3,000 |
| Documented losses, same year | −$6,000 |
| Taxable amount | $4,000 |
| Tax at 30% | $1,200 |
| Could come back | $1,800 |
For a 2026 or later tax year, only 90% of the losses count: $5,400. That leaves $4,600 to tax, $1,380 at 30%, and $1,620 that could come back.
Questions about the figure
It’s a rough estimate, and nothing is guaranteed. The IRS decides the final amount, based on your slips and the losses you can document.
Losses from gambling in the U.S. in the same year as your win, that you can show. A casino win/loss statement can be useful supporting documentation, together with dated records and other available evidence.
U.S. tax generally isn’t withheld on a nonresident’s winnings from blackjack, baccarat, craps, roulette and the big-6 wheel. If no U.S. tax was withheld, there generally is no withholding tax refund to claim for that payment. The calculator is for wins the casino took 30% from, such as a slot jackpot.
