Form W-2G, Certain Gambling Winnings: Withholding and the Loss Cap

Form W-2G, Certain Gambling Winnings, is the tax form a casino, racetrack, sportsbook, lottery, or poker room sends you when a payout meets an IRS reporting threshold. For 2026, that threshold is generally $2,000. The payer sends one copy to you and another to the IRS, so the agency already knows about the win before you file. Your job is to report the winnings on your Form 1040 and claim any tax the payer already withheld as a credit.

When a W-2G Gets Issued in 2026

Starting with payments in calendar year 2026, the minimum reporting threshold for Form W-2G rose to $2,000 across gambling categories and will be adjusted for inflation going forward.1Internal Revenue Service. Instructions for Forms W-2G and 5754 The specific trigger depends on the game:

Table games like blackjack, craps, roulette, and baccarat fall under “other wagering transactions.” Because the 300-times-the-wager rule applies, a W-2G for these games is rare. A $10 blackjack bet would need to pay out at least $3,000 to meet both the ratio test and the $2,000 threshold. The winnings are still taxable even when no form is issued.

What Each Box on the Form Means

Form W-2G is a single page. A few boxes carry most of what you need at tax time.4Internal Revenue Service. Form W-2G – Certain Gambling Winnings

Box 1 shows the reportable winnings. For keno and poker tournaments, this figure is already net of the wager or buy-in; for slots and bingo, it is the full payout with no deduction.3Internal Revenue Service. Instructions for Forms W-2G and 5754 Box 2 is the date of the winning event, not necessarily the day you were paid. Box 3 describes the type of wager. Box 4 shows any federal income tax the payer already withheld and sent to the IRS on your behalf. Box 7 covers winnings from identical wagers in some pari-mutuel and sports betting situations. Boxes 14 through 17 hold state and local withholding information when applicable.

The payer’s name, address, and employer identification number sit in the upper-left area. Keep your Copy C with your tax records for at least three years after filing.

Withholding on the Form

Two kinds of withholding can appear in Box 4, and they never apply together.

Regular gambling withholding is a flat 24% and applies when your winnings minus your wager exceed $5,000 on sweepstakes, wagering pools, lotteries, pari-mutuel wagers on horse or dog races or jai alai (if at least 300 times the bet), or sports wagering (if at least 300 times the bet). It does not apply to bingo, keno, or slot machine winnings at any amount.3Internal Revenue Service. Instructions for Forms W-2G and 5754

Backup withholding, also 24%, applies when you fail to give the payer your taxpayer identification number.5Internal Revenue Service. Backup Withholding For poker tournaments, the payer enters zero in Box 4 unless the winner has not provided a TIN, in which case backup withholding applies instead.

Non-cash prizes such as cars or vacation packages have a higher rate: 31.58%. The payer cannot pull cash from a physical prize, so the rate is grossed up so the IRS receives the equivalent amount, and the winner typically has to pay that withholding to the payer in cash when the prize is awarded.3Internal Revenue Service. Instructions for Forms W-2G and 5754

Whatever amount appears in Box 4 is a prepayment. Your actual tax depends on your total income, filing status, and deductions, so the 24% or 31.58% figure may be more or less than what you actually owe.

Reporting the Winnings on Your Return

Gambling winnings are fully taxable. Report them on Schedule 1 (Form 1040) under “Other Income,” and the total flows to your Form 1040 as part of adjusted gross income.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses Federal tax withheld in Box 4 goes on the payments section of your 1040, functioning as a credit just like withholding from a W-2.

One point trips up many people: you owe tax on every dollar of gambling winnings for the year, not only on payouts that generated a W-2G. A $500 sportsbook payout below the reporting threshold is still taxable income, and the IRS says so directly.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses

Deducting Gambling Losses

You can offset winnings by deducting losses, but the rules are stricter than most people expect, and 2026 brought a significant change.

The 90-Percent Cap Starting in 2026

Under the One Big Beautiful Bill Act, the deduction for gambling losses is now limited to 90% of your losses for the year, and in all cases cannot exceed your total reported winnings. Before 2026, losses were deductible dollar-for-dollar up to winnings. Now, even if losses exactly match winnings, only 90% of those losses is deductible. The law also expands “losses from wagering transactions” to include any deduction incurred in carrying on a wagering activity, which sweeps in expenses like travel and lodging for people who gamble as a business.

You Have to Itemize

Gambling losses are claimed as “Other Itemized Deductions” on Schedule A.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses Take the standard deduction and you get no benefit from your losses at all. For taxpayers whose mortgage interest, state taxes, and charitable contributions don’t exceed the standard deduction, gambling losses provide zero relief.

The AGI Effect

Even when losses fully offset winnings on Schedule A, the winnings still sit in your adjusted gross income because they land on Schedule 1 before itemized deductions are calculated. A higher AGI can reduce income-based credits, trigger premium tax credit repayments, and phase out other deductions. Winning and losing $20,000 at the casino in a year is not a wash: the AGI increase can affect the rest of your return.

Keep a Diary

The IRS expects an accurate diary or similar record if you plan to deduct losses. Your log should include the date and type of each wager, the name and location of the establishment, and the amounts won and lost.7Internal Revenue Service. Diary or Similar Record Tickets, receipts, statements, and player-card records back the diary up. Without documentation, the deduction can be disallowed entirely on audit.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses

Shared Winnings and Non-Cash Prizes

When a group splits a winning ticket or jackpot, the person collecting the money fills out Form 5754 to identify each member of the group and their share.8Internal Revenue Service. About Form 5754, Statement by Person(s) Receiving Gambling Winnings The payer then issues a separate W-2G to each person for their portion. Without Form 5754, the entire jackpot is reported under one Social Security number, and that person owes the full tax unless they can prove the split later, which is far harder after the fact.

Non-cash prizes like cars, trips, and merchandise are reported at fair market value in Box 1, with withholding at the 31.58% rate described above.3Internal Revenue Service. Instructions for Forms W-2G and 5754

If Your W-2G Hasn’t Arrived

Payers must furnish Copy B of Form W-2G to winners by January 31 following the calendar year of the win. Their deadline for filing with the IRS is February 28 on paper or March 31 electronically. If January 31 falls on a weekend, the deadline shifts to the next business day. If nothing has arrived by mid-February, contact the payer directly. You are required to report the income on your return whether or not the form ever shows up.

Nonresident Aliens

If you are not a U.S. citizen or resident alien, gambling winnings are generally subject to a flat 30% withholding under sections 1441(a) and 1442(a), and the payer reports them on Form 1042-S rather than Form W-2G. A tax treaty between your country and the United States may reduce or eliminate that rate, but a valid ITIN is needed for any treaty benefit to apply. Winnings from blackjack, baccarat, craps, roulette, the big-6 wheel, and certain pari-mutuel wagers initiated outside the United States are exempt from both withholding and reporting for nonresident aliens.1Internal Revenue Service. Instructions for Forms W-2G and 5754 Nonresident aliens who are not residents of Canada generally cannot deduct gambling losses. Filing is done on Form 1040-NR with Schedule NEC.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses
