How much you pay in taxes on casino winnings depends on your total income for the year: the IRS treats a jackpot the same as wages, so it gets added to everything else you earned and taxed at your federal bracket rate, which runs from 10% to 37% for 2026. On larger wins the casino will usually withhold 24% before handing you the money, and most states with an income tax take a cut as well. The actual bill often lands higher than the withholding, because a big win can push part of your income into a bracket you don’t normally touch.
Your Federal Rate on a Casino Win
Federal law defines gross income as income “from whatever source derived,” and gambling winnings sit squarely inside that definition.1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Slots, table games, poker tournaments, sports bets, and the fair market value of non-cash prizes all count.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses You’re supposed to report every dollar, including winnings too small to trigger a form from the casino.
Because those winnings are ordinary income, they run through the same graduated brackets as wages. For 2026, a single filer pays 10% up to $12,400, 12% up to $50,400, 22% up to $105,700, 24% up to $256,225, 32% and 35% in the upper tiers, and 37% on income above $640,600. Married couples filing jointly hit those brackets at roughly double the thresholds, with the top rate starting at $768,700.3Internal Revenue Service.

The stacking effect is what catches people. Say you earn $45,000 in wages and win $20,000 at a casino. Your gross income becomes $65,000, and part of that win crosses from the 12% bracket into the 22% bracket. The tax on the win itself works out higher than your usual rate, even though your salary alone would have kept you comfortably below the line. Very large wins can walk you through several brackets in a single year.
What the Casino Takes at the Window
Two things can happen when you cash out a big win, and they’re often confused. The casino may issue you a Form W-2G reporting the win to the IRS, and separately it may withhold 24% for federal tax. These are different obligations with different triggers.
When a W-2G Gets Issued
The casino must file a W-2G when your winnings hit game-specific thresholds. Starting January 1, 2026, the One Big Beautiful Bill Act raised the slot and bingo threshold from $1,200 to $2,000. The rest of the thresholds are: $1,500 or more on keno (reduced by the wager), and $600 or more on other wagers if the payout is at least 300 times the amount bet, or $5,000 or more from sweepstakes, wagering pools, and certain parimutuel pools. You get a copy of every W-2G, and so does the IRS, which will match them against your return.
When 24% Gets Withheld
Mandatory 24% federal withholding kicks in on gambling proceeds over $5,000 that are at least 300 times the wager.4Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source State lottery and sweepstakes winnings over $5,000 are withheld without the 300-times test. Slots, keno, and bingo are specifically exempt from this automatic withholding.5eCFR. 26 CFR 31.3402(q)-1 – Extension of Withholding to Certain Gambling Winnings You still owe tax on those wins; the casino just won’t take it from you at the cage.
If you can’t or won’t give the casino a valid Taxpayer Identification Number on a W-2G payout, backup withholding of 24% applies, including on slot and bingo wins that would otherwise be exempt. Whatever gets withheld is a prepayment against your annual tax, not a separate tax. If your bracket is below 24%, some of it comes back at filing time. If your bracket is higher, you owe the difference.
Offsetting Winnings With Losses
You can deduct gambling losses against your gambling winnings, but three limits shape how much that actually helps.6Office of the Law Revision Counsel. 26 USC 165 – Losses
Losses can never exceed winnings. Win $5,000 and lose $8,000 over the year, and you can deduct $5,000. The extra $3,000 doesn’t carry to next year and doesn’t reduce your wages.
Starting in 2026, the One Big Beautiful Bill Act caps the deduction at 90% of your winnings instead of the previous 100%. On $5,000 in winnings, the most you can deduct is $4,500, so even a break-even year leaves $500 of taxable gambling income. This 10% haircut applies whether you gamble casually or for a living.
You also have to itemize on Schedule A to claim any of it. The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One Big Beautiful Bill If your total itemized deductions including gambling losses don’t clear that number, itemizing costs you money and the loss deduction is effectively unavailable.
Backing up the deduction requires records. The IRS expects a contemporaneous log with the date, type of gambling, casino name and location, people you were with, and the amounts won and lost per session. Player’s club statements, ATM receipts, and W-2G forms support the log; a rough year-end estimate does not.
Non-Cash Prizes
Winning a car or a vacation package doesn’t avoid the tax. The IRS values non-cash prizes at fair market value and adds that amount to your gross income.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses A $35,000 car is $35,000 of income. The awkward part is paying tax on something that isn’t cash, and casinos often require you to cover the withholding upfront before releasing the prize. Some winners sell the prize to cover the bill.
State Taxes on Top
Most states with an income tax also tax gambling winnings, at rates that vary from zero in no-tax states to roughly 9% or more in high-tax states. Some apply a flat rate; others fold winnings into their bracket system.
If you win in a state other than your home state, both may claim tax. Reciprocity or credit provisions usually prevent true double taxation: your home state credits you for tax paid where the win happened. If your home state has no income tax, you still owe tax to the state where the casino operates. Keep records of where each win occurred.
If Gambling Is Your Job
The Supreme Court held in Commissioner v. Groetzinger that a person is a professional gambler when they gamble “full-time, in good faith, and with regularity, to the production of income for a livelihood.”7Justia Law. Commissioner v. Groetzinger, 480 US 23 (1987) There’s no hour or dollar threshold; the IRS looks at whether gambling functions as your occupation.
Professional status lets you file on Schedule C and deduct business expenses like travel, lodging, and training on top of losses. It also subjects your net gambling income to self-employment tax at 15.3%, covering Social Security (12.4% on net earnings up to $184,500 for 2026) and Medicare (2.9% on all net earnings).8Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security An additional 0.9% Medicare surtax hits earnings above $200,000 for single filers or $250,000 for joint filers. The 90% loss and expense cap applies to professionals too.
Visitors From Outside the U.S.
If you’re not a U.S. citizen or resident, winnings at a U.S. casino face a flat 30% withholding, taken before you receive the money.9Office of the Law Revision Counsel. 26 USC 1441 – Withholding of Tax on Nonresident Aliens Non-resident aliens generally cannot deduct losses unless the income is effectively connected with a U.S. trade or business. Some countries have tax treaties that reduce or eliminate the 30%; claiming a treaty rate means filing Form 1040-NR with Schedule NEC. IRS Publication 901 lists treaty countries.
If You Don’t Report
Every W-2G goes to the IRS, so leaving one off your return usually generates a notice. Winnings below the W-2G threshold are still reportable by law. The failure-to-pay penalty is 0.5% of the unpaid balance per month, capped at 25%, with interest compounding daily. If you deduct losses you can’t substantiate, the IRS can disallow the deduction and add an accuracy-related penalty of 20% on the resulting underpayment. A contemporaneous log and your W-2G copies are the defense.
