Casino taxes work on a simple principle with a lot of fine print: every dollar you win gambling is taxable federal income, the casino withholds tax and files paperwork once your payout crosses certain thresholds, and you can only cancel out those winnings by deducting your losses if you itemize. Starting with tax year 2026, that loss deduction is capped at 90% of what you lost, which means even a break-even year can leave you owing tax.
When the Casino Reports and Withholds
Casinos file Form W-2G with the IRS when your payout crosses game-specific thresholds. The One Big Beautiful Bill Act, signed July 4, 2025, raised the reporting floor for slots, bingo, and keno to a uniform $2,000 beginning in 2026, and that figure will adjust for inflation in later years.1Federal Register. Increase in Threshold for Requiring Information Reporting With Respect to Certain Payees
For 2026, the W-2G triggers are:
- Slots and bingo: $2,000 or more from a single session.
- Keno: $2,000 or more after subtracting your wager.
- Poker tournaments: more than $5,000 after the buy-in.
- Sports betting and similar wagers: $2,000 or more, and at least 300 times the amount wagered.2Internal Revenue Service. Instructions for Forms W-2G and 5754 (Rev. January 2026) Draft
Table games are the notable exception. Blackjack, craps, roulette, and similar games generally don’t produce a W-2G no matter how much you win, because they fall outside the reporting categories.3Internal Revenue Service. Instructions for Forms W-2G and 5754 That does not make table winnings tax-free. It only means no paperwork is being filed on your behalf, and the reporting obligation shifts entirely to you.
When winnings are large enough, the casino also withholds federal tax before you leave. The regular rate is a flat 24%, triggered when net winnings (payout minus wager) exceed $5,000 from lotteries, sweepstakes, wagering pools, and certain other wagers meeting a 300-to-1 payout ratio.4eCFR. 26 CFR 31.3402(q)-1 – Extension of Withholding to Certain Gambling Winnings Withholding is a prepayment, not a final tax. If your actual bracket is higher, you’ll owe more in April; if it’s lower, some comes back as a refund.
Reporting Winnings on Your Tax Return
Report gambling income on Schedule 1 of Form 1040, on the line labeled “Gambling.”5Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income Enter the full amount won, before any withholding was taken out. Any 24% withheld and shown on your W-2G goes in the federal income tax withheld section of the main 1040, the same place wage withholding from a W-2 lands.
The W-2G thresholds control when the casino reports to the IRS. Your own reporting obligation has no dollar floor. A $500 blackjack afternoon, a $50 winning parlay, a $20 scratcher — all taxable, all reportable. The IRS states plainly that you must report all gambling winnings, including those not reported on a W-2G.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses The agency has no automatic feed for small table wins, but it does match every W-2G filed against your return, and a missing one draws a letter.
Timing matters when you hit something big. If withholding doesn’t cover your actual tax rate, waiting until April can trigger an underpayment penalty. The IRS charges the penalty when you owe more than $1,000 at filing and didn’t pay enough through withholding or quarterly estimates during the year, so a large jackpot may call for an estimated payment in the quarter you win it.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Deducting Losses Under the New 90% Cap
You can offset winnings with gambling losses, but 2026 changed how much of your loss actually counts. Under the amended 26 U.S.C. § 165(d), your deduction is limited to 90% of the losses you incurred during the year, and that reduced number still cannot exceed your total winnings. The rule applies to all taxable years beginning after December 31, 2025.7Office of the Law Revision Counsel. 26 USC 165 – Losses
An example makes the math obvious. Win $10,000 and lose $10,000 in the same year, and you used to walk away with zero taxable gambling income. Now, 90% of $10,000 is $9,000, so you can deduct $9,000 against the $10,000 in winnings and owe tax on the remaining $1,000, even though you actually broke even at the tables. The larger your losses, the wider that gap gets.
Two older rules still apply and often matter more than the 90% cap:
- You have to itemize. Gambling losses go on Schedule A. If you take the standard deduction (in 2026, $16,100 for single filers and $32,200 for married filing jointly), your losses give you nothing. Most casual gamblers land here.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- Losses do not carry forward. Anything you can’t use against gambling winnings in the same tax year is gone. You cannot apply gambling losses to wages, interest, or any other type of income.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Why Winnings Inflate Your AGI Even When You Break Even
Winnings sit on the income side of your return, on Schedule 1. Losses sit on the deduction side, on Schedule A. That structural split means your adjusted gross income rises with your winnings and stays there, because losses are not subtracted above the line.
AGI drives eligibility for a long list of things beyond your tax bracket. A big jackpot can push you into a higher Income-Related Monthly Adjustment Amount for Medicare Part B and Part D premiums, phase out marketplace premium tax credits, shrink education credits, and trigger the net investment income tax. Retirees are especially exposed, because a single large win can cascade into higher costs the following year that outrun the actual income tax on the winnings.
Non-Cash Prizes
Win a car, a trip, or a television, and the IRS treats it the same as cash. You report the item’s fair market value as gambling income.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses Fair market value is roughly what you’d pay at retail.
The awkward part is paying cash tax on a non-cash prize. A $40,000 car can produce an $8,000-plus federal tax bill depending on your bracket, before state tax. Selling the prize is a common answer, but the sale doesn’t reduce your reported amount. You still report the fair market value on the date you won.
Splitting a Jackpot With a Group
When two or more people share a payout, the person who physically collects fills out IRS Form 5754 at the cage, listing each recipient’s name, taxpayer identification number, and share. The casino then issues a separate W-2G to each person for their portion.3Internal Revenue Service. Instructions for Forms W-2G and 5754
Skip Form 5754 and the entire jackpot gets reported under one Social Security number. That person owes tax on all of it, and unwinding the situation later means amended returns and correspondence with the IRS. Filling out the form at the window is the easy path.
Professional vs. Recreational Gamblers
Most players are casual gamblers to the IRS. A smaller group qualifies as professionals: people who gamble regularly with the intent to earn a profit and treat the activity like a business. The IRS weighs factors like separate accounts, detailed session records, study of strategy, and a realistic potential for long-term profit — volume alone is not enough.
Professional status shifts the reporting to Schedule C, which allows deductions for ordinary business expenses like travel and analytical tools. The tradeoff is self-employment tax of 15.3% on net profits, plus quarterly estimated payments. And the 90% cap follows professionals into their business: the amended statute defines “losses from wagering transactions” to include deductions incurred in carrying on a wagering business, so professional expenses are pulled into the same limit.7Office of the Law Revision Counsel. 26 USC 165 – Losses That’s a meaningful change from prior years, when professionals could deduct losses and expenses up to the full amount of winnings.
State Tax on Gambling Winnings
Most states with an income tax also tax gambling winnings, and many require the casino to withhold state tax at certain payout levels. State withholding generally runs somewhere between 3% and 9%, with the exact rate and trigger set by each state. A handful of states have no personal income tax, so residents there deal only with the federal side.
Winning at an out-of-state casino often means filing a nonresident return in the state where you played, even if your home state has no income tax. Some states have reciprocity or credits, others don’t. Checking the specific state’s rules is the only way to avoid a surprise bill months later.
Foreign Nationals
Nonresident aliens operate under a separate set of rules. Winnings are generally subject to a flat 30% withholding rate, reported on Forms 1042 and 1042-S rather than a W-2G. Winnings from blackjack, baccarat, craps, roulette, and big-6 wheel are exempt from both withholding and reporting.9Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026) Tax treaties may reduce or eliminate the 30% rate for residents of certain countries.
Records That Hold Up in an Audit
The IRS will not take your word for what you won or lost. If you claim a loss deduction and get audited without documentation, you lose the deduction. The agency requires an accurate diary or similar record of your gambling activity, backed by receipts, tickets, statements, or other records showing both sides of the ledger.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses
A workable diary captures the date and type of each session, the casino’s name and location, what you started with, what you finished with, and the net. Players club statements, ATM receipts from the venue, and credit card records all reinforce the log. The people who lose in audits are almost always the ones reconstructing records after the fact. Keep the log as you go, even if it lives in a notes app, and the numbers will hold up.
