Under federal law, there is no minimum amount of gambling winnings you have to report — every dollar is taxable income and belongs on your tax return, whether you won it at a slot machine, a poker table, a sportsbook, or a church raffle. The dollar figures you may have heard about ($600, $1,200, $5,000) are thresholds for when the casino sends the IRS a form about you. They are not thresholds for when the income becomes taxable. It already is.
No Minimum, No Exceptions
Federal tax law defines gross income as “all income from whatever source derived,” and gambling winnings fall squarely within that definition.1Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined A $50 scratch-off winner and a $50,000 slot jackpot follow the same rule. Both go on the return.
That includes cash payouts from casinos, sportsbooks, poker games, lotteries, raffles, and fantasy sports contests. It also includes non-cash prizes: if you win a car or a vacation package, the fair market value counts as income.2Office of the Law Revision Counsel. 26 USC 74 – Prizes and Awards Casino comps like complimentary hotel rooms and meals are technically taxable at their fair market value too, though the IRS rarely pursues enforcement on smaller ones.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Winnings are taxed as ordinary income, at the same rates as your wages.
The Dollar Amounts That Trigger a W-2G
Casinos and other payers must file Form W-2G with the IRS, and give you a copy, once your winnings from a particular game hit a set threshold. This is what people usually mean when they ask how much has to be reported, so it’s worth being precise about the numbers:
- Bingo: $1,200 or more, not reduced by the amount wagered.
- Slot machines: $1,200 or more, not reduced by the amount wagered.
- Keno: $1,500 or more, after subtracting the cost of the wager.
Those three games have their own dedicated regulation setting out exactly when a payer must issue the form.4eCFR. 26 CFR 1.6041-10 – Return of Information as to Payments of Winnings From Bingo, Keno, and Slot Machine Play
For most other gambling — horse racing, sports betting, and non-casino wagers — a W-2G is issued when winnings reach $600 or more and the payout is at least 300 times the original wager. Both conditions have to be met. Poker tournaments and sweepstakes use a higher trigger: reporting kicks in when net proceeds (winnings minus buy-in) exceed $5,000.5Office of the Law Revision Counsel. 26 U.S. Code 3402 – Income Tax Collected at Source – Section: (q) Extension of Withholding to Certain Gambling Winnings
The point many gamblers miss: not receiving a W-2G does not mean the income is tax-free. You owe the same tax on a $900 blackjack session as on a $1,200 slot hit. The form only determines whether the IRS already has an independent record of the win. The IRS is explicit that you must report winnings “including winnings that aren’t reported on a Form W-2G.”3Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Table Games and the No-Form Trap
Blackjack, craps, roulette, and baccarat almost never produce a W-2G. The IRS’s gaming threshold chart lists no specific W-2G trigger for these games, because the house can’t cleanly track net results hand by hand.6Internal Revenue Service. Gaming Withholding and Reporting Threshold
This trips people up. No form arrives, so table players sometimes assume there is nothing to report. The reporting obligation is on you regardless. The IRS can surface unreported table game winnings through bank deposit analysis, lifestyle audits, or the currency transaction reports casinos file for cash transactions of $10,000 or more. When bank deposits don’t match reported income, the gap itself can draw scrutiny.
When Tax Gets Withheld Before You Even Leave
Some winnings are large enough that the payer holds back federal income tax before paying you out. For 2026, the withholding rate is 24%, applied to winnings over $5,000 (after subtracting the wager) from sweepstakes, wagering pools, lotteries, and sports betting.7Internal Revenue Service. Instructions for Forms W-2G and 5754 Bingo, keno, and slot machine winnings are exempt from that mandatory withholding even when they cross $5,000.5Office of the Law Revision Counsel. 26 U.S. Code 3402 – Income Tax Collected at Source – Section: (q) Extension of Withholding to Certain Gambling Winnings
A separate backup withholding rule kicks in at 24% if you don’t give the payer a correct taxpayer identification number, whenever the winnings meet the applicable reporting threshold.8Internal Revenue Service. Backup Withholding Bring valid ID and your Social Security number to the cage or you’ll surrender nearly a quarter of a reportable win on the spot.
Withholding is not a separate tax. It’s a prepayment against your annual bill, the same way payroll withholding works. If your actual rate on that income is under 24%, the difference comes back as a refund. If it’s higher, you’ll owe the rest at filing.
Where the Numbers Go on Your Return
All gambling winnings go on Schedule 1 (Form 1040) as other income. That total then flows into Form 1040 and lands in your adjusted gross income.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses Enter every W-2G you received individually. Tax software handles this automatically once you input each form.
If a payer withheld federal tax, the amount is in Box 4 of your W-2G. Enter it with your other withholding so you get credit for it against your total tax. Paper filers attach copies of every W-2G to the return. Electronic filers don’t mail anything but should keep the forms for at least three years.
Deducting Losses Against Winnings
You can offset gambling winnings with gambling losses, but only if you itemize deductions on Schedule A. Take the standard deduction and your losses do nothing for you.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses The deduction is also capped at your reported winnings: win $8,000 and lose $12,000, and you deduct $8,000.
Starting with the 2026 tax year, the One Big Beautiful Bill Act adds a second limit. You can deduct only 90% of your gambling losses, even when losses equal or exceed winnings. It applies to casual and professional gamblers alike, and it covers expenses tied to gambling activity.
The practical effect: win $10,000 and lose $10,000 in 2026, and you can deduct only $9,000. You owe tax on $1,000 of “phantom” income even though you walked away flat. Frequent gamblers who typically break even are the ones who feel this most.
Records the IRS Will Actually Accept
The IRS expects an accurate diary or similar record, maintained as you gamble and backed up by documentation.9Internal Revenue Service. Know the Five Important Tips on Gambling Income and Losses For each session, note:
- The date.
- The type of activity — slots, poker, sports bets, keno, and so on.
- The location, including the name and address of the casino, track, or online platform.
- How much you won and lost.
- The names of anyone with you.
Keep the supporting paper too: W-2G forms, losing tickets, betting slips, bank statements showing casino withdrawals, and credit card records. Online sportsbooks and casino apps usually offer downloadable annual win/loss statements. Save those, but don’t lean on them as your only proof. The IRS treats the contemporaneous diary as the primary record and the other documents as corroboration.
What Happens If You Don’t Report
Every W-2G the casino files is copied to the IRS. Automated matching compares those forms to your return, and a mismatch generates a notice proposing additional tax. It’s one of the easiest discrepancies for the agency to catch, because the computer does the work.
The consequences add up:
- Back taxes plus interest, calculated daily from the original due date at the federal short-term rate plus three points.
- A 20% accuracy-related penalty on the underpaid tax. Failing to report income shown on a W-2G is specifically cited as the kind of negligence that triggers it.10Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments
- A civil fraud penalty of 75% of the underpayment if the IRS determines the omission was intentional. Rare on small amounts, realistic on repeated deliberate non-reporting.
Winnings with no W-2G attached can still surface in an audit. Large or frequent cash deposits, spending that doesn’t match reported income, and casino currency transaction reports all give the IRS threads to pull.
