How Gambling Winnings Are Taxed

Enter your total winning bets, total losing bets, and other income. The calculator applies the 2026 federal brackets and the new 90% loss limitation, and shows the number that surprises high-volume bettors: taxable income on money never kept. Every output is an estimate.

The tax code treats gambling winnings as ordinary gross income, full stop. Casino games, sports bets, poker, raffles, daily fantasy, sweepstakes, and lotteries all land in the same bucket: reportable income at your regular marginal rate, whether or not a form was issued and whether the money arrived as chips, an app balance, or a check.

The part that surprises people: casual gamblers cannot simply net their wins and losses and report the difference. Each winning wager is income; losing wagers are a separate itemized deduction with their own limits (Section 3). A bettor who won $30,000 of individual bets and lost $28,000 does not report $2,000 of income; they report $30,000 of income and then deduct losses only if they itemize.

Because withholding rarely applies, a good gambling year usually creates a quarterly estimated tax obligation. The mechanics and safe harbor rules are covered in our estimated tax penalty guide.

Payers must report wins to the IRS on Form W-2G once they cross set thresholds. The thresholds vary by game, and the copy the IRS receives carries your Social Security number, which is what powers the automated matching notices later.

Withholding is narrower than reporting. The payer generally withholds a flat 24% only when the win exceeds $5,000 and comes from a lottery, sweepstakes, wagering pool, or a bet paying at least 300 times the wager. Refuse to provide a taxpayer identification number and 24% backup withholding applies regardless of the amount. Everything else, including most slot jackpots and sports bets, pays out with zero withholding, and the full tax is due with your return.

Three conditions gate every loss deduction. You must itemize (standard-deduction filers get nothing). Losses cannot exceed winnings (no carryover of the excess). And the deduction covers wagering losses, not the related costs a casual gambler racks up along the way.

Starting with the 2026 tax year, the One Big Beautiful Bill Act added a fourth: only 90% of wagering losses are deductible. Win $100,000 and lose $100,000 in the same year, and you deduct $90,000 while reporting the full $100,000, paying tax on $10,000 of phantom income. High-volume bettors who churn large amounts at close to break-even feel this rule the hardest. Repeal bills have been introduced, but as of this writing the 90% limit is the law for 2026.

Legal sports betting moved gambling from cash on a casino floor to a fully documented account ledger. Every wager, win, and withdrawal sits in the sportsbook's records, and the annual statements plus W-2Gs give the IRS a clean matching target. The practical effect: app bettors get caught by automated underreporter notices far more often than cash gamblers ever did.

The reporting math is the same as the casino floor: each winning bet is income, and losing bets are itemized deductions under the limits above. The volume is what changes. A recreational app bettor can easily generate six figures of gross winning bets in a year while netting close to zero, which after the 90% rule produces genuine tax on money never kept. Download the annual statement every January and hand it to your preparer whole.

One adjacent trap: promotional winnings, free-bet conversions, and referral bonuses are also income. If a windfall arrived some other way this year, a prize, a crowdfunding campaign, a settlement, the same reserve-and-estimate playbook applies; see our GoFundMe taxes guide for the crowdfunding rules.

A professional gambler, someone who wagers full time, with regularity, as an actual livelihood, reports on Schedule C like any business owner: winnings as gross receipts, wagering losses and business expenses as deductions. The bar for professional status is high and fact-driven; a profitable hobby with a spreadsheet does not qualify.

Professional status does not escape the loss limits. Since 2018, a professional's wagering losses and gambling-related expenses combined cannot exceed winnings (no net loss to carry against other income), and the 2026 90% limitation is layered on top. What Schedule C status does offer is above-the-line treatment (no itemizing required) and deductible ordinary business expenses inside the cap, at the price of self-employment tax on net profit.

States with no income tax take nothing. Most other states tax gambling winnings as ordinary income at their regular rates, and several are less generous than the federal rules on the loss side, limiting or disallowing the loss deduction entirely, which can make a break-even year taxable at the state level even before the federal 90% rule.

Winning out of state can create a nonresident filing obligation where the bet was placed, with a credit in your home state. Lottery prizes have their own state quirks, including California's exemption for its own lottery, covered in our lottery winner tax guide and the state dropdown on the lottery tax calculator.

1. Reporting only the W-2G amounts.

The W-2Gs are what the IRS already knows about, not the whole obligation. App statements showing winnings far above the W-2G total are the classic underreporter trigger.

2. Netting wins and losses on the income line.

Casual gamblers who report only their net result have understated gross income, even when the bottom-line tax would have been similar. The income line and the itemized loss deduction are separate, and the 90% rule now makes the difference real money.

3. Spending the win before the tax.

With no withholding on most wins, the tax bill arrives at filing season. Reserve the marginal rate off the top the week the money lands, and check whether a quarterly estimate is due before the next deadline.

4. No log until the audit letter.

The loss deduction survives on contemporaneous records. Start the log with the first bet of the year, not the first letter from the IRS.
