It's important for you to know the thresholds that require income reporting by the payer. Winnings in the following amounts must be reported to the IRS by the payer: $600 or more at a horse track (if that is 300 times your bet) $1,200 or more at a slot machine or bingo game.

In the United States, the threshold for a "taxable event" on a slot machine is $1,200 in a single win. If you hit a jackpot of $1,200 or more (not including your original wager), the machine will lock up, and a casino attendant will bring you a W-2G form. The casino is required by the IRS to report this win, and while they don't always withhold taxes on the spot for U.S. citizens, you are legally obligated to report the income on your annual tax return. In 2026, the IRS continues to enforce this strictly, although there have been ongoing legislative pushes by the gaming industry to raise this limit to $5,000 to account for inflation, as the $1,200 limit has not changed since 1977. For "table games" like Blackjack or Roulette, the rules are different; you generally only trigger a tax form if you win $600 or more AND the payout is at least 300 times the amount of the wager. It is a "pro-tip" to keep a log of your losses, as the IRS allows you to deduct gambling losses up to the amount of your winnings, provided you have the documentation to prove it.
