Gambling Winnings Taxation and Loss Deduction Rules
Question askedHow does gambling winnings get taxed and how do i deduct losses? What do I need to provide to prove losses and what kind of losses qualify?
Quick answer: All gambling winnings are fully taxable and must be reported as income, but losses are only deductible if you itemize, and even then only up to the amount of your winnings — you can't net them together. This assumes the 2025 tax year.
How winnings are taxed
Gambling winnings are reported as ordinary income. As IRS Publication 17 explains, you may have received a Form W-2G, Certain Gambling Winnings, showing the amount of your gambling winnings and any tax taken out of them, and you include the amount from box 1 on Schedule 1 (Form 1040), line 8b, and include the amount shown in box 4 on Form 1040 or 1040-SR, line 25c, as federal income tax withheld.
This includes non-cash prizes: you must include in your income the fair market value of bonds, cars, houses, and other noncash prizes. It also covers fantasy sports — Publication 525 notes you must include your gambling winnings in your income on Schedule 1 (Form 1040), line 8b, and winnings from fantasy sports leagues are gambling winnings.
If you win a lottery paid in installments, generally, if you win a state lottery prize payable in installments, you must include in your gross income the annual payments and any amounts you receive designated as interest on the unpaid installments. If you sell the future payments for a lump sum, you must report the amount you receive from the sale as ordinary income (on Schedule 1 (Form 1040), line 8b) in the year you receive it.
Withholding: Income tax is withheld at a flat 24% rate from certain kinds of gambling winnings — winnings of more than $5,000 from any sweepstakes, wagering pool (including poker tournament payouts), or lottery, or any other wager if the proceeds are at least 300 times the bet. Note: gambling winnings from bingo, keno, and slot machines generally aren't subject to income tax withholding, though you may need to provide the payer with a social security number to avoid backup withholding.
Deducting losses
The key rule: you must report the full amount of your gambling winnings for the year on Schedule 1 (Form 1040), line 8b, and you deduct your gambling losses for the year on Schedule A (Form 1040), line 16 — you can't deduct gambling losses that are more than your winnings. Critically, you can't reduce your gambling winnings by your gambling losses and report the difference — you must report the full amount of your winnings as income and claim your losses (up to the amount of winnings) as an itemized deduction, so your records should show your winnings separately from your losses.
This means losses are only usable if you itemize deductions on Schedule A instead of taking the standard deduction.
What losses qualify: Gambling losses include the actual cost of wagers plus expenses incurred in connection with the conduct of the gambling activity, such as travel to and from a casino.
What you need to prove losses
You need contemporaneous records: you must keep an accurate diary or similar record of your losses and winnings, containing at least the date and type of your specific wager, the name and address or location of the gambling establishment, the names of other persons present with you, and the amount(s) you won or lost.
Beyond the diary, in addition to your diary, you should also have other documentation — you can generally prove your winnings and losses through Form W-2G, Form 5754, wagering tickets, canceled checks, substitute checks, credit records, bank withdrawals, and statements of actual winnings provided by the gambling establishment. Different games have specific suggested records — for example, for slot machines, a record of the machine number and all winnings by date and time the machine was played.
Important limits: if you're in the trade or business of gambling, use Schedule C (Form 1040), and for tax years 2018 through 2025, professional gambling losses and expenses are limited to the amount of your winnings. Also, generally, nonresident aliens can't deduct gambling losses on your Schedule A (Form 1040-NR).
Given how fact-specific loss documentation and professional-gambler status determinations can be, it's worth having a CPA review your records and filing approach.
