Tax on Gambling Winnings: Withholding, W-2G, and Losses

The tax on gambling winnings at the federal level is simply your ordinary income tax rate, which runs from 10% to 37% in 2026 depending on your total taxable income for the year. Every dollar you win from a casino, lottery ticket, sports bet, raffle, or office pool counts as taxable income, and so does the fair market value of any non-cash prize like a car or a vacation. You owe the tax whether or not the payer hands you any paperwork.¹ The 24% figure you may have seen quoted is just the automatic withholding rate on larger payouts, not your final bill.

Your Actual Rate on a Win

Gambling winnings stack on top of your other income and get taxed at whatever marginal bracket the combined total lands in. For 2026, single filers face these federal brackets:

10% up to $12,400
12% from $12,401 to $50,400
22% from $50,401 to $105,700
24% from $105,701 to $256,225
32% from $256,226 to $201,775
35% from $403,551 to $640,600
37% over $640,600

Married couples filing jointly get wider brackets; the 22% rate, for instance, runs from $100,801 to $211,400.²

So a $10,000 jackpot does not automatically cost $2,400. If your other income already sits in the 12% bracket and the winnings do not push you past $50,400, you owe $1,200. A high earner in the 37% bracket owes $3,700 on the same $10,000.

When the Payer Withholds 24% Upfront

Casinos, lotteries, and other gambling venues must withhold 24% of your winnings when the payout minus your wager exceeds $5,000. That applies to sweepstakes, wagering pools, lotteries, and sports bets. For horse racing, dog racing, jai alai, and sports bets, the $5,000 threshold applies only when the payout is also at least 300 times the original wager.³

The 24% is a prepayment, not the final tax. If your effective rate for the year comes in lower, the difference comes back as a refund. If your rate is higher, you owe the balance when you file. Refusing to give the payer your Social Security number or taxpayer ID triggers backup withholding, also at 24%.⁴ Withholding your information does not stop the money from going to the IRS; it just makes claiming credit for it harder.

When You Get a Form W-2G

For 2026, the IRS raised the reporting threshold for Form W-2G to $2,000, with annual inflation adjustments after that. That is a significant jump from prior thresholds of $1,200 for slot machines and bingo and $1,500 for keno. The specific triggers by game type:

Slot machines and bingo: $2,000 in winnings.
Keno: $2,000 in winnings minus the wager.
Poker tournaments: $2,000 in winnings minus the buy-in.
Sweepstakes, lotteries, and wagering pools: $2,000 when winnings are at least 300 times the wager.
Sports betting and horse racing: $2,000 when winnings are at least 300 times the wager.

Fewer W-2G forms will circulate in 2026, but the tax obligation is unchanged. You still owe tax on every win, including the $50 scratch-off nobody reports. Payers must give you the W-2G at the time of the payout or by January 31 of the following year.³

Reporting Winnings on Your Return

All gambling winnings go on line 8b of Schedule 1 (Form 1040), which flows into total income on the main return.⁵ Report the full amount of winnings before subtracting any losses. Losses, if you deduct them, go on Schedule A separately.

Federal tax already withheld shows up in Box 4 of your W-2G. Add that to the withholding total on Form 1040 so you receive credit for what has already been sent in.¹ Even without a W-2G, winnings below the reporting threshold still belong on the return. The IRS cross-references payer records against what you file, and unreported gambling income is a common audit trigger.

Estimated Payments After a Big Win

A large payout that came in without withholding, or with 24% that will not cover your actual bracket, may require an estimated tax payment to avoid a penalty. The IRS runs a pay-as-you-go system, and falling behind during the year can produce an underpayment penalty at filing time.

You generally avoid the penalty if any of the following applies:

You owe less than $1,000 after withholding and refundable credits.
You have paid at least 90% of your current year’s tax through withholding and estimated payments.
You have paid at least 100% of last year’s tax through withholding and estimated payments.

⁶

After a mid-year jackpot, a single estimated payment shortly afterward is often the simplest way to stay in compliance.

Deducting Gambling Losses

You can deduct gambling losses, but only if you itemize on Schedule A instead of taking the standard deduction. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.² Unless your combined itemized deductions (mortgage interest, state taxes, charitable gifts, and gambling losses) exceed that amount, itemizing just to claim losses will raise your tax bill instead of lowering it.

Even when itemizing works, losses have a hard cap: you can never deduct more than you report in winnings. Win $5,000 and lose $7,000, and the deduction tops out at $5,000. The extra $2,000 disappears. It cannot carry forward and cannot offset wages or investment income.¹ Winnings raise your income; losses can only bring it back to where it started, never below.

Session Netting for Slot Play

A safe harbor method lets electronically tracked slot machine players net wins and losses within a single session, defined as one calendar day at one gaming establishment on one type of game. Feed $500 into machines over a day and cash out $350, and you report a $150 loss for that session rather than tracking every spin.⁷

Sessions at different casinos on the same day count separately, and you cannot net a gain in one session against a loss in another. Each session stands on its own.⁷

How a Big Win Ripples Through the Rest of Your Return

Because winnings raise your adjusted gross income, they can trigger consequences beyond the tax on the winnings themselves. The ripple hits retirees and moderate-income households hardest.

Higher AGI can make more of your Social Security benefits taxable, with up to 85% becoming taxable once combined income crosses certain thresholds. A single big win can push a retiree past those lines even when their other income is modest. For Medicare enrollees, gambling income counts toward the modified adjusted gross income used to calculate Part B and Part D premium surcharges. One strong year at the casino can mean higher monthly premiums two years later, since Medicare uses the return from two years prior.

AGI also affects income-based tax credits and the deductibility of medical expenses, which only count above 7.5% of AGI. A $20,000 jackpot raises that floor by $1,500, potentially wiping out a medical deduction you would have qualified for.

State Taxes

Most states with an income tax treat gambling winnings as taxable, but rates, thresholds, and rules for deducting losses vary. Some states do not allow any loss deduction. Win money in a state where you do not live and you may need to file a nonresident return there, then claim a credit on your home state return to avoid double taxation. A few states have no income tax at all, but residents of income-tax states still owe their home state’s tax on winnings earned in tax-free states. Check with your state’s revenue department for the specifics that apply to you.

If You Are Not a U.S. Resident

Foreign nationals who win money gambling in the United States are generally subject to a flat 30% withholding rate, reported on Form 1042-S rather than Form W-2G. Tax treaties with certain countries can reduce or eliminate that rate. Blackjack, baccarat, craps, roulette, and big-6 wheel are exempt from both withholding and reporting for nonresident aliens.³

If Gambling Is Your Job

The IRS treats someone who gambles full time, in good faith, with regularity, and for a livelihood as being in a trade or business.¹ Professionals report on Schedule C rather than splitting winnings and losses between Schedule 1 and Schedule A. That lets them net wins and losses directly and deduct ordinary business expenses like travel, lodging, tournament entry fees, and handicapping subscriptions. The offset is self-employment tax, roughly 15.3% on net earnings, for Social Security and Medicare. Few gamblers qualify, and the IRS scrutinizes these returns closely.

Records That Hold Up in an Audit

The IRS wants a contemporaneous diary of your gambling activity. Your log should record:

The date and type of each wager
The name and location of the gambling establishment
The names of anyone with you during the session
The amounts won or lost

⁸

Back the diary up with losing tickets, betting slips, casino player-card statements, canceled checks, and bank records showing payments to gambling venues. W-2G forms document your reported wins, but the burden of proving losses falls entirely on you. Without a paper trail, the IRS will let your reported winnings stand while disallowing every dollar of loss you claimed, turning a break-even year into a real tax bill.
