Form W-2G: Reporting Gambling Winnings
Form W-2G reports certain gambling winnings to you and to the IRS. A casino, sportsbook, lottery, or other payer issues it when a payout hits a game-specific threshold, and it shows both the amount won and any federal tax withheld. For 2026, the slot and bingo reporting threshold rose to $2,000, and gambling losses face a new 90% deduction cap under the One Big Beautiful Bill Act (OBBBA).
You report all gambling winnings as income whether or not you receive a Form W-2G. The form is a payer’s information return, not a measure of what is taxable. Below are the 2026 thresholds by game, the 24% withholding rules, and how the loss deduction works after OBBBA.
What is Form W-2G?
Form W-2G, “Certain Gambling Winnings,” is the information return a payer files with the IRS and gives to a winner when a payout meets a reporting threshold. It lists gross winnings in Box 1, the date, the type of wager, and federal income tax withheld in Box 4. You use it to report winnings on Schedule 1 of your Form 1040.
The payer, not the gambler, files the form. You may receive several W-2Gs in one year from different casinos, sportsbooks, or the state lottery. Copies go to the IRS, so unreported W-2G income is a common trigger for an automated underreporter notice (CP2000). Winnings not large enough for a W-2G are still fully taxable and belong on your return.
Form W-2G reporting thresholds by game (2026)
Reporting thresholds differ by game type. For 2026, the OBBBA raised the flat slot machine and bingo threshold to $2,000 (up from $1,200) and keno to $2,000 net of the wager (up from $1,500). Lotteries, sweepstakes, wagering pools, and pari-mutuel bets (horse racing, dog racing, jai alai) and sports wagering report at $600 and 300 times the wager. Poker tournaments report at $5,000 net.
The $2,000 flat threshold is new. It first appeared for the 1977 slot rule at $1,200 and stayed there for nearly 50 years. Under the OBBBA amendment to IRC sections 6041(a) and 6041A(a)(2), the minimum threshold is $2,000 for payments in 2026 and will be indexed for inflation each year after.
| Game type | 2026 W-2G reporting threshold | Prior threshold |
|---|---|---|
| Bingo | $2,000 or more (gross) | $1,200 |
| Slot machines | $2,000 or more (gross) | $1,200 |
| Keno | $2,000 or more (net of wager) | $1,500 |
| Poker tournaments | $5,000 or more (net of buy-in) | $5,000 (no change) |
| Lotteries, sweepstakes, wagering pools | $600 or more AND at least 300x the wager | $600 / 300x |
| Horse/dog racing, jai alai, sports wagering | $600 or more AND at least 300x the wager | $600 / 300x |
The 300-times rule applies to pari-mutuel and pooled bets: a payout can top $600 and still not require a W-2G if it is under 300 times the bet. A $600 payout on a $10 bet (60x) generates no W-2G, but a $600 payout on a $1 bet (600x) does. These per-game rules can vary in how a specific payer applies them, so keep your own records regardless.
The 24% withholding on gambling winnings
Two separate 24% withholding rules can apply. Regular gambling withholding takes 24% of proceeds when winnings minus the wager exceed $5,000 and are at least 300 times the wager. Backup withholding takes 24% when you fail to give the payer a correct taxpayer identification number (TIN) and the winnings hit the reporting threshold. Both are federal income tax prepaid on your behalf.
Regular gambling withholding applies to sweepstakes, wagering pools, lotteries, and other wagers meeting the $5,000-and-300x test. The payer withholds 24% of the proceeds (winnings minus the wager) and reports it in Box 4. For noncash prizes such as a car or a trip, if the payer pays the tax rather than deducting it, the rate is grossed up to 31.58% of the fair market value net of the wager.
Backup withholding is the fallback when no regular withholding applies and you did not furnish a valid TIN (or the IRS flagged your account). It also runs at 24% and shows in Box 4. Withheld amounts are a credit against your final tax, so you may owe more or get some back depending on your bracket, which often exceeds or falls below 24%.
Deducting gambling losses in 2026: the OBBBA 90% limit
Gambling losses are deductible only if you itemize on Schedule A, and only up to your gambling winnings for the year. Starting in 2026, the OBBBA caps the deduction at 90% of losses. So a taxpayer with $10,000 of winnings and $10,000 of losses may deduct $9,000, not the full $10,000, and pays tax on the $1,000 gap.
The 90% limit is the change to watch. Before 2026, losses could offset winnings dollar for dollar up to the amount won. Now the deductible figure is the lesser of 90% of losses or 90% of winnings, which means even a break-even year can produce taxable “phantom” income. Losses can never exceed winnings, and unused losses do not carry forward to future years.
Two other points matter. First, this is an itemized deduction: if you take the standard deduction (in many cases the better choice), you get no loss deduction at all, yet you still report every dollar of winnings. Second, deductible “wagering losses” can include integral costs of placing a bet, such as a mandatory tournament entry fee, but not general travel or lodging for a casual gambler.
Bills to repeal the 90% cap and restore full offset have been introduced in both the House and Senate with bipartisan support, but as of mid-2026 none has passed. Treat the 90% limit as current law and plan around it. For how the itemizing decision works overall, see the guidance below.
Worked example: a break-even year under the 90% cap
A recreational gambler wins $40,000 and loses $40,000 in 2026. Because the deduction is capped at 90% of losses, she may itemize only $36,000. She reports $40,000 of winnings on Schedule 1 and $36,000 of losses on Schedule A, leaving $4,000 of net taxable gambling income despite breaking even economically.
If she takes the standard deduction instead, she still reports the full $40,000 as income and deducts none of the losses. She should compare itemizing (with the capped loss plus her other itemized deductions) against the standard deduction and pick the larger total. The standard vs itemized deduction tradeoff decides which path costs less.
How to report Form W-2G on your tax return
Report all gambling winnings, W-2G or not, as “Other income” on Schedule 1 (Form 1040), line 8b. Enter federal tax withheld from Box 4 of each W-2G on Form 1040 as federal income tax withheld. If you itemize, claim allowable losses (capped at 90% starting in 2026) on Schedule A. Keep a contemporaneous log of sessions, dates, amounts, and venues.
Professional gamblers follow different rules. A person in the trade or business of gambling reports on Schedule C and may deduct ordinary business expenses, though the 90% cap on wagering losses under OBBBA reaches professionals too. Whether gambling rises to a trade or business depends on regularity, continuity, and profit motive, and it can vary by facts and circumstances.
Keep records even when no W-2G arrives. The IRS matches W-2Gs to returns, and a solid log supports both your income figure and any loss deduction if questioned. Session records, wagering statements from the casino’s player card, and bank records are the usual proof. See Schedule 1 (Form 1040) for where additional income lands on the return.
Frequently asked questions
Do I have to report gambling winnings if I did not get a W-2G?
Yes. All gambling winnings are taxable income regardless of whether a payer issues Form W-2G. The form is a reporting trigger tied to game-specific thresholds, not a definition of what is taxable. A $50 lottery scratcher win or a $300 sports bet payout is still income and belongs on Schedule 1 (Form 1040), line 8b, even with no form in hand.
What is the W-2G threshold for slot machines in 2026?
For 2026, a slot machine or bingo payout of $2,000 or more triggers a Form W-2G. This is up from the long-standing $1,200 figure under the One Big Beautiful Bill Act, which set a flat $2,000 threshold indexed for inflation in later years. Keno rose to $2,000 net of the wager. Payouts below $2,000 are still taxable but generate no form.
How much tax is withheld from gambling winnings?
Federal withholding is generally 24%. Regular gambling withholding of 24% applies when proceeds (winnings minus the wager) exceed $5,000 and are at least 300 times the wager. Backup withholding of 24% applies if you do not give the payer a correct TIN. Noncash prizes where the payer covers the tax are grossed up to 31.58% of fair market value net of the wager.
Can I deduct gambling losses in 2026?
You can deduct gambling losses only if you itemize on Schedule A, only up to your winnings, and starting in 2026 only up to 90% of losses under the OBBBA. A $10,000 loss against $10,000 of winnings yields a $9,000 deduction, leaving $1,000 taxable. If you take the standard deduction, you deduct nothing, yet you still report all winnings as income.
What happens if I do not report a W-2G?
The IRS receives its own copy of every W-2G and matches it against your return. Omitting W-2G income often produces an automated CP2000 underreporter notice proposing additional tax, plus interest and possible penalties. Reporting the winnings and, if you itemize, claiming allowable losses avoids the mismatch. Keep a session log so your reported figure is defensible.
Are gambling losses deductible above the amount I won?
No. Deductible gambling losses can never exceed your gambling winnings for the year, and starting in 2026 the deduction is further capped at 90% of losses under the OBBBA. Excess losses are not deductible and do not carry forward to future years. This is why a break-even gambler can still owe tax on a slice of winnings that the capped loss deduction does not offset.
