Every dollar you win from gambling is taxable, and reporting gambling winnings to the IRS is your responsibility whether or not the casino, sportsbook, or lottery hands you a tax form. Starting in 2026, payers must file a Form W-2G with the IRS once your winnings from a single event reach $2,000, an amount that will now adjust each year for inflation.1Internal Revenue Service. Instructions for Forms W-2G and 5754 Winnings below that line still count as income and still belong on your return.
What Counts as Reportable Gambling Income
The IRS treats winnings from casinos, sportsbook apps, state lotteries, raffles, sweepstakes, office pools, horse racing, poker tournaments, and informal bets as taxable income. You must report all of it, from every source, regardless of whether you received paperwork.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Non-cash prizes count too. If you win a car, a vacation, or merchandise, you owe tax on the fair market value of the prize, meaning what the item would sell for on the open market. The organization running the event should send you a W-2G or a Form 1099-MISC showing the value, but the reporting obligation is yours even if nothing arrives in the mail.
When the Payer Files a W-2G in 2026
The $2,000 threshold that takes effect in 2026 replaces the older $1,200 trigger for slots and bingo and the $1,500 trigger for keno. The specifics still vary by game:
- Slot machines and bingo: $2,000 or more in winnings.
- Keno: $2,000 or more after subtracting the wager on the winning game.
- Poker tournaments: $2,000 or more after subtracting the buy-in.
- Horse racing, sports betting, and other wagering: $2,000 or more, but only if the payout is also at least 300 times your wager.
- Sweepstakes, lotteries, and wagering pools: $2,000 or more in winnings.
That 300-times rule matters most for sports bettors. A $100 bet that pays $5,000 is 50 times the wager, so no W-2G goes out even though the winnings are well above $2,000. The tax on that $5,000 is still yours to report and pay.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses
When a W-2G is filed, one copy goes to you and one goes to the IRS, so the agency already knows about that payout before you file your return. The payer will ask for your Social Security number and a photo ID to complete the form.3Internal Revenue Service. About Form W-2G, Certain Gambling Winnings
Withholding at the Payout
Two different withholding rules can pull tax from your winnings at the moment of payout. Both use a 24% rate, but they trigger in different situations.
Regular gambling withholding applies when the net payout (winnings minus wager) exceeds $5,000 and the money came from a sweepstakes, lottery, or wagering pool, or from horse racing, sports betting, or other wagering where the payout is at least 300 times the wager.4Office of the Law Revision Counsel. 26 U.S. Code 3402 – Income Tax Collected at Source Bingo, keno, slot machines, and poker tournaments are exempt from regular gambling withholding.1Internal Revenue Service. Instructions for Forms W-2G and 5754
Backup withholding, also at 24%, applies when a winner doesn’t give the payer a correct taxpayer identification number and regular withholding isn’t already in play. It can hit any type of gambling, including bingo, keno, and slots, once the winnings reach the reporting threshold.5Internal Revenue Service. Backup Withholding Providing your Social Security number when asked is the simplest way to avoid it.
Withholding is an advance payment, not a settlement. You still owe whatever your actual tax works out to at filing time, and if 24% wasn’t enough, you’ll owe the balance.
How to Report It on Your Return
All gambling income goes on Schedule 1 (Form 1040), on the line for gambling winnings. That total then flows to your Form 1040 and gets taxed at your ordinary rates.6IRS. 2025 Schedule 1 (Form 1040) – Additional Income and Adjustments to Income W-2G or no W-2G, every source belongs on that line.
If you had a big win and the payer didn’t withhold enough to cover the tax, you may need to make estimated payments during the year rather than wait until April. Form 1040-ES sets up those quarterly payments and helps you avoid an underpayment penalty on top of the balance due.7Internal Revenue Service. About Form 1040-ES, Estimated Tax for Individuals The standard filing deadline is April 15 of the year after you had the winnings.
Deducting Gambling Losses
Losses are deductible, but under two strict conditions. You must itemize on Schedule A instead of taking the standard deduction, and you can never deduct more in losses than the gambling winnings you reported for the year.8GovInfo. 26 U.S. Code 165 – Losses
Say you won $8,000 and lost $12,000 over the course of the year. You can deduct $8,000. The other $4,000 gives you no tax benefit and doesn’t carry forward. Losses are claimed as “Other Itemized Deductions” on Schedule A, so a casual gambler whose itemized deductions wouldn’t otherwise beat the standard deduction won’t see any benefit from writing off losses.
A separate rule applies if gambling is your full-time trade or business rather than a recreational activity: professional gamblers report on Schedule C, and starting in 2026 their combined deduction for losses and related business expenses is capped at 90% of gambling winnings.
Records the IRS Expects You to Keep
The IRS expects a diary or similar log covering your gambling activity for the year. At a minimum, your records should show:
- The date and type of each wager or gambling activity
- The name and location of the gambling establishment
- The names of anyone with you at the time
- The amount you won or lost on each occasion
Keep supporting documents as well: W-2G forms, wagering tickets, canceled checks, credit card records, and payout slips.9Internal Revenue Service (IRS). Diary or Similar Record These records matter most if you claim loss deductions; without them the IRS can disallow the deductions entirely.
Split Winnings With a Group
When more than one person shares a winning ticket or wager, the person who collects the payout isn’t the only one who has to report it. The collector completes Form 5754, listing each member of the group and each person’s share. The payer then issues a separate W-2G to each winner for their portion.10Internal Revenue Service. About Form 5754, Statement by Person(s) Receiving Gambling Winnings Skip that step and the whole payout lands under one Social Security number, leaving that person to explain the numbers to the IRS.
State Return Considerations
Most states with an income tax also tax gambling winnings, and the same amounts you report to the IRS generally have to appear on your state return. If you won in a state other than where you live, you may need to file a nonresident return in the state where the payout happened and then claim a credit on your home-state return so the same dollars aren’t taxed twice. State withholding rates on gambling payouts vary, and a call to your state revenue department is worth the time if you have out-of-state winnings.
Penalties for Skipping It
Because the IRS already has a copy of every W-2G the payer files, unreported winnings are easy to spot. Leaving them off your return can bring several penalties at once:
- Accuracy-related penalty of 20% of the underpayment, if the IRS finds you underpaid because you left gambling income off the return.11Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments
- Failure-to-file penalty of 5% of the unpaid tax for each month or part of a month the return is late, up to 25%.12Internal Revenue Service. Failure to File Penalty
- Interest on the unpaid tax, running from the original due date until you pay it off, compounded daily.
When the IRS finds the omission was intentional, a civil fraud penalty of 75% of the underpayment can take the place of the accuracy-related penalty. Criminal prosecution for gambling income alone is rare but possible in cases of large, deliberate concealment.
