Gambling Winnings and Form W-2G: What to Report
Published November 4, 2026
Gambling winnings are taxable income. That includes winnings from lotteries, raffles, sports betting, horse races, and casinos. It includes cash and the fair market value of prizes such as cars and trips. The rules here apply to casual gamblers, meaning people who are not in the trade or business of gambling. IRS: Topic no. 419, Gambling income and losses
Report all winnings
You must report all gambling winnings on your return, including winnings that do not appear on a Form W-2G. You report them on Form 1040 or Form 1040-SR, using Schedule 1 (Form 1040). IRS: Topic no. 419
What Form W-2G is
A payer issues Form W-2G, Certain Gambling Winnings, when you receive certain winnings, or when your winnings have federal income tax withheld. The form shows the winnings and any tax withheld. Whether a form is required depends on the type of gambling, the amount, and generally how the winnings compare with the amount you bet. IRS: About Form W-2G
If tax was withheld, the amount is shown in box 4 of Form W-2G. Keep that form with your records. IRS: Instructions for Forms W-2G and 5754
For a noncash prize, such as a car in a sweepstakes or a lottery, the payer must use the fair market value of the prize when it decides whether reporting or withholding applies. IRS: Instructions for Forms W-2G and 5754
Backup withholding and your TIN
If you do not give the payer a correct taxpayer identification number (TIN), the payer may use backup withholding. The rate is a flat 24%. The payer applies it to certain reportable payments. Our post on backup withholding and Form W-9 explains how TIN rules work. IRS: Topic no. 307, Backup withholding
Common mistakes
- No form, no income. You must report all gambling winnings, even when no Form W-2G is issued.
- Prizes count too. A car or a trip counts at its fair market value, not only the cash.
- Losses without itemizing. You can deduct gambling losses only when you itemize, so a standard deduction filer cannot deduct them.
Form W-2G also has boxes for state and local winnings and tax withheld (boxes 13 through 18). Check those boxes against your state return, if your state taxes gambling winnings. IRS: Instructions for Forms W-2G and 5754
Losses
You can deduct gambling losses only if you itemize deductions on Schedule A (Form 1040). Your deduction cannot be more than the gambling income you reported. You claim losses up to the amount of your winnings as "Other Itemized Deductions." IRS: Topic no. 419
Keep records
To deduct losses, keep an accurate diary or similar record of your winnings and losses. Keep receipts, tickets, statements, or other records that show the amount of both. If you use an online gambling account, save its statements too. IRS Publication 529 has more detail. IRS: Publication 529
Estimated tax
Gambling winnings can add to your income. You may need to pay estimated tax on that added income. IRS Publication 505 explains the rules. IRS: Publication 505
If you win a large amount and little or no tax is withheld, plan for the tax before you file. Withholding and estimated payments are the two ways tax is paid during the year.
Steps to take
- Gather your tickets, statements, and any Form W-2G you received.
- Add all winnings for the year, including winnings with no Form W-2G.
- Check the tax withheld in box 4 of each Form W-2G.
- Keep a log of your bets, winnings, and losses.
- If you itemize, claim losses on Schedule A, up to the amount of your winnings.
