Gambling taxes work like this: the IRS treats every dollar you win from casinos, lotteries, sportsbooks, poker rooms, raffles, or online platforms as ordinary income, and you report it on your federal return whether or not the payer sent you a form. You can offset winnings with losses, but only if you itemize, and starting with tax year 2026 the deduction is capped at 90% of what you lost. Large wins often come with 24% federal withholding taken on the spot, which acts as a prepayment against the tax you’ll ultimately owe.
What the IRS Considers a Gambling Win
Cash from a slot machine, a sports bet, a bingo hall, a horse race, a lottery ticket, or a friendly poker game all count.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses So do non-cash prizes at fair market value: win a $45,000 car in a sweepstakes and you owe tax on $45,000. Raffle prizes, charity auction winnings, and even proceeds from illegal gambling are taxable. The IRS cares that you received value, not how you got it.
Casino comps like free rooms, meals, and show tickets are technically taxable too, though they’re rarely reported on a W-2G.
When Casinos Report Your Winnings to the IRS
Payers don’t file paperwork on every win. They issue a Form W-2G only when your winnings cross game-specific thresholds. For 2026, the One Big Beautiful Bill Act raised the base reporting threshold to $2,000, with annual inflation adjustments going forward.2Internal Revenue Service. Instructions for Forms W-2G and 5754 The old $1,200 trigger for slots and bingo is gone.
- Bingo and slot machines: W-2G at $2,000 in winnings for 2026.
- Keno: W-2G when winnings minus the wager reach $2,000 for 2026.
- Poker tournaments: W-2G when winnings minus the buy-in reach the reporting threshold.
- Sweepstakes, lotteries, and wagering pools: W-2G when winnings minus the wager exceed $5,000.
- Sports betting and parimutuel wagers: W-2G when winnings minus the wager exceed $5,000 and the payout is at least 300 times the wager.
Blackjack, craps, roulette, and baccarat don’t trigger automatic W-2G reporting at the table. The instructions simply don’t list them, largely because tracking session-level results at a table game is impractical for the casino.2Internal Revenue Service. Instructions for Forms W-2G and 5754 The winnings are still taxable. You’re just responsible for tracking them yourself.
Withholding at the Cage
Reporting and withholding aren’t the same thing. A W-2G tells the IRS what you won. Withholding actually sends money to the Treasury on your behalf. Regular gambling withholding of 24% applies when your winnings minus the wager exceed $5,000 on sweepstakes, lotteries, wagering pools, parimutuel betting (if winnings are at least 300 times the wager), or sports wagering (same 300-times rule).2Internal Revenue Service. Instructions for Forms W-2G and 5754 It does not apply to bingo, keno, or slot machine winnings.
If you refuse to give a valid Social Security number when collecting a reportable win, the payer must apply backup withholding at 24% regardless of the game.3Internal Revenue Service. Backup Withholding
The 2026 Change to Loss Deductions
Losses can offset winnings, but the rules tightened this year. Under the revised 26 U.S.C. ยง 165(d), you can deduct only 90% of your wagering losses, and only up to the amount you won.4Office of the Law Revision Counsel. 26 USC 165 – Losses Before 2026, the deduction covered 100% of losses up to winnings.
The math: win $20,000, lose $20,000, and you still report $20,000 as income. Your deductible losses come to $18,000 (90% of $20,000). That leaves $2,000 in taxable gambling income on a year where you didn’t actually come out ahead. And if losses exceed winnings, you can’t apply the excess against wages or investment income.
You Have to Itemize
The loss deduction lives on Schedule A. If you take the standard deduction, you get nothing.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.5Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your total itemized deductions don’t clear that number, you pay tax on the full amount of your winnings with no offset. Casual gamblers get caught by this constantly.
Why a Break-Even Year Still Costs You
This is where gambling taxes get quietly expensive. Winnings go on the income side and lift your adjusted gross income. Losses go on Schedule A. The two never cancel on the AGI line, even when they’re identical. Win $30,000 and lose $30,000, and your AGI still rises by $30,000.
An inflated AGI can chip away at benefits you’d otherwise qualify for: premium tax credits for marketplace health insurance, the earned income tax credit, the child tax credit, the medical expense deduction, and education-related tax breaks all phase out or shrink as AGI climbs. A break-even year at the casino can quietly cost you thousands in lost credits.
Reporting on Your Return
All gambling winnings for the year, including anything not reported on a W-2G, go on Schedule 1 of Form 1040 as other income, then flow into your AGI on the main return.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses Report the full amount before any loss deduction. If you itemize, losses go on Schedule A as other itemized deductions, subject to the 90% cap and the winnings ceiling.4Office of the Law Revision Counsel. 26 USC 165 – Losses
Records the IRS Expects You to Keep
The IRS wants a contemporaneous gambling diary, meaning you write down each session close to when it happens rather than reconstructing the year at tax time. The diary should include:
- The date and type of each wager or gambling activity
- The name and address of the gambling establishment
- The names of anyone with you
- The amounts you won or lost during each session
Back the diary up with W-2G forms, wagering tickets, canceled checks, credit card records, bank statements showing ATM withdrawals at gambling venues, and lottery ticket receipts.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
A common mistake: assuming the casino’s annual win/loss statement is enough. It isn’t. The IRS requires you to keep your own records. Casino statements can support your diary, but they don’t replace it, they miss cash play that wasn’t tracked through a loyalty card, and they sometimes report net figures rather than session-by-session results. If audited with only a casino printout in hand, you’re in a weak position.
Estimated Tax After a Big Win
When a casino withholds 24% off a jackpot, that prepayment usually covers most of your federal liability. The problem shows up with wins that aren’t withheld: table game payouts, sports bets under the threshold, or a run of smaller wins that add up. If you expect to owe $1,000 or more in tax after withholding and credits, the IRS generally requires quarterly estimated tax payments.7Internal Revenue Service. 2026 Form 1040-ES Estimated Tax for Individuals
The 2026 quarterly deadlines are April 15, June 15, September 15, and January 15, 2027. You can avoid the underpayment penalty by paying at least 90% of the current year’s tax or 100% of last year’s tax through withholding and estimated payments combined. If your prior-year AGI was above $150,000, that safe harbor rises to 110%.8Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty Hit a six-figure jackpot in October and wait until April to deal with it, and you’ll almost certainly owe a penalty.
When a Group Splits a Jackpot
If coworkers pool for a lottery ticket or friends share a slot machine payout, the person who physically collects the money should file Form 5754 with the payer. That form identifies each winner, their Social Security numbers, and each person’s share.9Internal Revenue Service. Form 5754 – Statement by Person(s) Receiving Gambling Winnings The casino or lottery office then issues a separate W-2G to each winner for their portion.
Skip this and the entire jackpot lands on one person’s Social Security number, making them liable for the full tax bill. Sorting it out later means each recipient has to report their share and the collector has to explain the discrepancy, which invites IRS attention.
A Few Situations With Different Rules
If gambling is your primary occupation and you pursue it with regularity and profit intent, the IRS may treat you as a professional gambler. Professionals report on Schedule C and can deduct business expenses like travel and tournament entry fees on top of wagering losses, but they also owe self-employment tax of 15.3% on net earnings, which casual gamblers don’t pay.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses The IRS scrutinizes professional status closely.
Non-U.S. citizens and non-resident aliens face a flat 30% withholding rate on U.S. gambling winnings, reported on Form 1042-S instead of a W-2G. Winnings from blackjack, baccarat, craps, and roulette are exempt from that withholding, and residents of roughly 25 treaty countries can claim a full exemption.10Internal Revenue Service. Publication 515 – Withholding of Tax on Nonresident Aliens and Foreign Entities
Federal tax isn’t the end of it. Most states with an income tax also tax gambling winnings at ordinary income rates, and some states don’t let you deduct gambling losses on the state return even if you itemize federally. That combination can leave you owing state tax on the full amount of your winnings. Nevada, Florida, Texas, and other states without an income tax don’t impose a separate gambling tax. Check your own state’s rules before assuming your federal loss deduction carries over.
