In the U.S., slot winnings are considered taxable income and must be reported on your federal tax return. Winnings are subject to federal income tax, and the casino may withhold a portion of your winnings if they exceed a certain threshold. Additionally, state tax implications vary by state, with some states imposing their own taxes on gambling winnings. Players are also allowed to deduct losses, but only up to the amount of their winnings. It’s essential for players to keep thorough records of their gambling activities, including wins and losses, to ensure accurate tax reporting.
