When it comes to gambling winnings, the tax reporting requirements differ depending on whether the winner is a U.S. resident or a non-U.S. person (international winner). Using the correct IRS form ensures proper withholding and compliance with U.S. tax law.
Form 1042-S for International Winners
-
Form 1042-S is issued to report U.S.-sourced income paid to non-U.S. persons, including international winners of gambling prizes.
-
It shows both the amount of the winnings and any U.S. tax withheld.
-
Casinos, poker tournaments, and other gambling organizations must provide Form 1042-S whenever a foreign national wins a prize subject to U.S. tax withholding.

Form W-2G for U.S. Citizens and Residents
-
Form W-2G applies to U.S. citizens and residents who win gambling prizes that meet IRS reporting thresholds.
-
It covers winnings from slot machines, lotteries, poker tournaments, and similar events.
-
Payers must issue a W-2G form when the winnings meet the IRS threshold, and winners are required to report the income on their U.S. tax return.
👉 Our W-2G filing software can help prepare, print, and e-file these forms with the IRS.
Key Takeaway
-
International winners → receive Form 1042-S.
-
U.S. winners (citizens/residents) → receive Form W-2G.
