Gambling Winnings Tax Calculator 2026: How Much Tax Do You Owe?

That includes money won from casinos, online gambling, slot machines, lotteries, raffles, sports betting, horse racing, poker, fantasy sports and sweepstakes. It can also include non-cash prizes: win a car, a holiday or another prize rather than cash, and its fair market value can still count as taxable income.

And here is the part people often miss: you do not need to receive a W-2G for the winnings to be taxable. The form is a reporting document. It is not the thing that makes the income taxable.

1. The W-2G reporting threshold increased

For payments made in 2026, the minimum reporting threshold used for Form W-2G is $2,000. That replaces the lower thresholds gamblers may remember: slot-machine and bingo winnings previously had a $1,200 reporting threshold, keno $1,500.

That does not mean every $2,000 win automatically produces a W-2G: different forms of gambling still have their own reporting conditions. And it definitely does not mean winnings below $2,000 are tax-free.

2. You can no longer deduct 100% of gambling losses

This is the bigger change. From 2026, the federal deduction for gambling losses equals 90% of the losses, and is allowed only to the extent of the winnings. Casual gamblers claim it as an itemized deduction.

That creates a strange result for someone who genuinely broke even: $10,000 won and $10,000 lost leaves $1,000 of winnings exposed to federal income tax, because only $9,000 of the losses can be deducted. It is probably the single most important gambling-tax change to understand in 2026.

The 24% figure is a federal withholding rate that applies to certain gambling payments. It is not a universal gambling tax rate.

For lotteries, sweepstakes, wagering pools, sports wagers and other qualifying bets, regular federal withholding applies when the winnings minus the wager exceed $5,000 and the IRS conditions are met. Winnings from bingo, keno and slot machines are not subject to regular gambling withholding, although backup withholding can apply in certain circumstances, including when the required taxpayer information is not provided.

The tax withheld is money paid toward your eventual federal tax bill. It is not necessarily the final amount you owe.

24% withheld is not a 24% final tax rate

Gambling winnings are added to your taxable income rather than put into a special flat-rate bucket. Federal individual income-tax rates for 2026 run from 10% to 37%, so a $5,000 win can affect two people differently: someone on a lower income may sit in a lower marginal bracket, while someone already earning a high income could have part of the extra income taxed at a much higher marginal rate.

If too much was withheld, you may get some back when you file. If too little was withheld, you may still owe tax. That is why a useful calculator needs more than one box asking how much you won.

Imagine a very active year: $25,000 of winning sessions and $22,000 of losing sessions. You may think you made $3,000 and should report $3,000. That is not generally how a casual gambler reports it federally. You report the gambling winnings as income. If eligible, you claim the permitted gambling losses separately as an itemized deduction, and from 2026 even that deduction is limited to 90% of the losses, up to the winnings.

Do you pay tax on slot-machine winnings?

Yes. Slot winnings can be taxable even if the casino withholds nothing when you cash out. The W-2G threshold for slot payments is $2,000 in 2026, but a $1,000 slot win with no form is still taxable income.

What about sports-betting winnings?

Sports-betting winnings are gambling income too. The 2026 W-2G instructions carry a specific section on sports wagering: reporting and withholding can depend on both the size of the winnings and how large they are compared with the original wager. Keep records of what you won and lost; a year-end net-result screen in a betting app is not a federal return.

What records should gamblers keep?

“I know roughly what I lost” is not a recordkeeping strategy. Keep W-2G forms, casino win/loss statements, sportsbook transaction histories, betting slips and tickets, deposit and withdrawal records, account statements, receipts, tournament records and a gambling diary showing the date, the venue or site, the type of gambling and the amounts wagered, won and lost. The IRS expects taxpayers claiming gambling losses to be able to substantiate the amounts.

What if tax was already withheld?

Check box 4 of your W-2G. Federal income tax withheld is reported with your other withholding when you file: a payment already made toward the bill, not proof that the gambling tax is settled. Depending on the complete return, the result can be additional tax due, roughly even, or a refund.

Do states tax gambling winnings too?

Potentially. Federal tax is only half the picture. Some states have no individual income tax, others tax gambling winnings, and the rules for deducting losses can differ from the federal rules. This calculator is a federal estimate and does not mix state assumptions into the result.
