How the treaty treats your gambling losses

Certain Canadian residents may deduct eligible U.S. gambling losses under treaty rules, subject to applicable limitations.

What the treaty says.

Qualifying Canadian residents may deduct documented U.S. gambling losses when calculating tax on eligible winnings.

Your potential refund depends on your winnings, eligible documented losses, and the rules for your tax year.

What counts as proof

Keep dated records that identify your gambling activity, including winnings and losses. The IRS may request supporting evidence.

  • A win/loss statement

    Request a yearly win/loss statement from the casino and retain any supporting transaction records.

  • Your other slips

    Keep all relevant Forms 1042-S and W-2G, along with supporting gambling records.

  • Your own record

    Maintain a dated record of gambling sessions, locations, amounts wagered, winnings and losses, with any available supporting documents.

The IRS decides how much of the withheld 30% comes back, based on your win and the losses you can document.

We handle this for you.

We review your supporting records and include allowable losses where permitted. Just send us your casino slip and any records of your losses, and we’ll take care of the rest.
