Form W-2G Requirements: Thresholds, Withholding, and Reporting

Form W-2G requirements determine when a casino, racetrack, sportsbook, lottery, or other gambling payer must report your winnings to the IRS and hand you a copy. For payments made in 2026, the general reporting floor rose to $2,000 as the IRS began adjusting the threshold for inflation, with a higher $5,000 net threshold for poker tournaments and a separate 300-times-the-wager test for horse racing, dog racing, jai alai, and sports betting.¹

Winnings Thresholds by Game Type

The dollar amount that triggers a W-2G depends on what you were playing:

Bingo and slot machines: a payout of $2,000 or more, regardless of the wager size or the odds.
Keno: net winnings (payout minus your wager) of $2,000 or more.
Horse racing, dog racing, jai alai, and sports betting: winnings of $2,000 or more, but only if the payout is also at least 300 times the wager. A $10 bet paying $3,000 qualifies. A $100 bet paying $2,500 does not, because the payout is 25 times the wager.²
Poker tournaments: net winnings (payout minus buy-in) of more than $5,000.¹

Not getting a W-2G does not make your winnings tax-free. Every dollar of gambling income is taxable whether or not the payer files a form.³

Table Games Are Not on the List

Blackjack, baccarat, craps, roulette, and big-6 wheel are not covered by the W-2G reporting categories, no matter how large the win.¹ The tax bill is the same. A $10,000 blackjack session is as taxable as a $10,000 slot jackpot; the difference is that nobody files a form for you, so your own records have to carry the weight.

How Multiple Wins Combine

Whether smaller hits stack together into a reportable total depends on the game.

For bingo, keno, and slot machines, an establishment may use optional aggregate reporting: reportable winnings paid to the same person within a single “gaming day” can be combined on one W-2G. A gaming day is a 24-hour period chosen by the payer, typically ending between 3:00 a.m. and 6:00 a.m. On December 31, all reporting periods must close at 11:59 p.m.²

For horse racing, sports betting, and similar wagers, the rule is different. Winnings from “identical wagers” are added together. Two bets are identical if they are placed with the same payer and depend on the same event or events; for horse and dog racing, they must also be in the same parimutuel pool. Poker tournaments are evaluated one at a time, so separate tournaments during the year are not combined to see whether a single one crosses the threshold.²

When Federal Tax Is Withheld

A W-2G does not automatically mean money was withheld from your payout. Two separate withholding rules can apply, both at 24%.

Regular Gambling Withholding

Regular withholding applies at a flat 24% of the net winnings when the net exceeds $5,000 and the wager is in a covered category: sweepstakes, wagering pools, lotteries (including state lotteries), parimutuel wagers on horse or dog races and jai alai (at the 300-times threshold), and sports wagers (also at the 300-times threshold).⁴ Bingo, keno, and slot machines are explicitly exempt from regular gambling withholding, even on very large payouts.¹

Backup Withholding

Backup withholding is triggered not by the size of the win but by a missing or incorrect taxpayer identification number, or by an IRS notice telling the payer the number on file is wrong. The rate is 24%, and it can apply to any reportable win, including bingo, keno, and slot payouts that would otherwise escape withholding.¹ Having valid ID ready at the cage is the simplest way to avoid it.

What the Form Captures

When a payout crosses a threshold, the payer collects your legal name, address, and taxpayer identification number, usually your Social Security number. The IRS instructions call for two forms of identification, one with a photograph. A driver’s license, passport, military ID, or tribal member card satisfies the photo requirement. A completed Form W-9 or a Social Security card can serve as the second.²

Key boxes on the form:

Box 1: gambling winnings. For keno and poker this is net of the wager or buy-in; for slot machines and bingo it is the full payout.²
Box 2: federal income tax withheld.
Box 4: date of the winning transaction.
Box 7: type of wager, such as “Slot Machine” or “Horse Race.”
Boxes 13–15: state tax information, including any state withholding in Box 15.¹

When a Group Shares the Winnings

If two or more people share a winning ticket or wager, the person who collects the money should not end up with a W-2G for the whole amount. Form 5754 splits it correctly. The person receiving the payment completes Part I with their information and the total; Part II lists each member of the group and their share. The payer then issues a separate W-2G to each winner for their portion only.⁵

If federal tax was withheld, the person who collected the payout must sign and date the form. If no withholding occurred, no signature is required. Skipping Form 5754 puts the full payout on one Social Security number and is much harder to unwind after the fact.

Non-Resident Aliens Follow Different Rules

Gambling winnings paid to non-resident aliens are not reported on Form W-2G. The default withholding rate is 30% of gross winnings, reported on Forms 1042 and 1042-S. A tax treaty between the U.S. and the winner’s home country can reduce or eliminate that rate, but only if the winner provides Form W-8BEN with a valid taxpayer identification number. Winnings from blackjack, baccarat, craps, roulette, and big-6 wheel are completely exempt for non-resident aliens, and no Form W-8BEN is required for that exemption.⁶

When You Should Get the Form

The payer must furnish Copy B to you by January 31 of the year following the year of the payment. In many cases the form is handed to you at the cage when you collect the payout.¹ If January 31 comes and goes without a form you were expecting, contact the payer before filing your return.

Putting a W-2G on Your Return

The amount in Box 1 goes on Schedule 1 of Form 1040 as other income. Any federal tax in Box 2 is credited against your total tax on Form 1040, either shrinking what you owe or adding to your refund. You still have to report all of your gambling winnings for the year, including the ones that never generated a form. That $800 blackjack session, the $50 office pool payout, and the $200 scratch-off all belong on the return.³

Deducting Losses

Recreational gamblers can deduct losses on Schedule A as an itemized deduction, but only up to the amount of gambling winnings reported. Winnings of $4,000 and losses of $6,000 produce a $4,000 loss deduction, not $6,000, and gambling losses cannot create a net loss that offsets other income.

For 2026, professional gamblers report gambling income and expenses on Schedule C, but a new limitation caps deductible wagering losses, including related business expenses like travel, at 90% of those losses. The total deduction still cannot exceed total gambling gains for the year.

State Taxes

Most states with an income tax also tax gambling winnings, and rules vary. States without an income tax impose nothing. Some states mirror the federal rules, and some run their own withholding on payouts above set amounts, which will show up in Box 15 of your W-2G. Whether your state lets you deduct gambling losses on the state return is a separate question with inconsistent answers by jurisdiction.

Records That Protect the Deduction

The IRS expects an accurate diary or similar log of all gambling activity, not just the sessions that produced a W-2G. The diary should show the date and type of each wager, the name and location of the establishment, the names of anyone with you, and the amounts won or lost. Keep supporting documentation alongside it: wagering tickets, canceled checks, credit records, bank withdrawal slips, and any W-2Gs you receive.⁷

This matters most when you claim losses. Without contemporaneous records, the IRS can disallow every dollar of the loss deduction while still taxing every dollar of the winnings. Most people who lose at audit remember their losses clearly but cannot prove them.
