Gambling Winnings Tax Calculator 2026

How Gambling Winnings Are Taxed in 2026

There is no special gambling tax rate. Gross winnings are ordinary income, reported on Schedule 1 as other income and taxed at the same 10% to 37% brackets that apply to your wages. Because winnings stack on top of everything else you earn, a good year at the sportsbook can push part of your income into the next bracket even if your salary never changed.

Payers withhold 24% under IRC Section 3402(q) on proceeds of more than $5,000 from lotteries, sweepstakes, wagering pools and sports wagering, with an additional 300-times-the-wager test for parimutuel and certain other wagering categories. That 24% is a prepayment, not the tax itself. If your marginal rate is 12%, you overpaid and get money back. If it is 35%, the withholding covered barely two thirds of the bill.

Reporting changed too. The general information-reporting floor rose from $600 to $2,000 for payments made in calendar year 2026, and the IRS applied that threshold to Form W-2G in its January 2026 draft instructions. A higher reporting floor changes what paperwork arrives in your mailbox, not what you owe. Winnings below any threshold are still taxable.

The OBBBA 90% Loss Cap and Phantom Income

Section 70114 of the One Big Beautiful Bill Act (P.L. 119-21) amended IRC Section 165(d) for tax years beginning after December 31, 2025. Two limits now apply, and the order matters:

1. Take 90% of your total wagering losses for the year.
2. Cap that result at your total winnings.

Run the break-even case. You win $100,000 and lose $100,000. Ninety percent of your losses is $90,000, which is below your winnings, so $90,000 is your deduction. You are taxed on $10,000 of income you never actually kept. That is phantom income, and at a 24% marginal rate it costs you $2,400 on a year where you finished exactly flat.

The pain has a ceiling. Once your losses reach your winnings divided by 0.9, roughly 111% of winnings, the winnings cap binds instead of the 90% factor and phantom income disappears. Below that line, every dollar of the gap is taxed. Above it, the extra losses vanish: there is no carryforward for casual gamblers, so a losing year buys you nothing next year.

Compare that with 2025 and earlier, where losses offset winnings in full up to the amount you won. A break-even year produced zero taxable gambling income. This calculator models 2026 only.

Why Most Bettors Cannot Deduct Losses at All

The 90% cap gets the headlines, but a bigger trap sits underneath it. Gambling losses for a casual gambler are an itemized deduction, claimed on Schedule A line 16. They are not an above-the-line adjustment, and they are worth exactly nothing to a filer who takes the standard deduction.

For 2026 the standard deduction is $16,100 for single and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household. Your gambling losses only help once your other itemized deductions plus your deductible losses clear that number. A bettor with no mortgage and modest state taxes frequently does not clear it, which means the full gross winnings are taxed and the loss column does nothing.

That is why this calculator asks for your other itemized deductions instead of making you flip a switch. It compares itemizing against the standard deduction for you and reports the deduction your losses actually bought, which is $0 for most standard-deduction filers no matter how large the loss column looks. Run the same comparison across your whole Schedule A with the Itemized vs Standard Deduction Calculator.

Record-Keeping, State Rules, and Professional Gamblers

Under the 90% cap, loss records matter more than they used to, because every documented dollar of loss is now worth only 90 cents of deduction and undocumented losses are worth nothing. Keep a session log with dates, locations or platforms, amounts wagered and amounts won or lost, and hold on to every Form W-2G (box 1 is the gross payout, box 4 is the federal tax withheld). Account statements and app histories from a sportsbook support the log; they do not replace it.

Rates are the smaller problem at the state level. The rules themselves differ. Several states, including Illinois, North Carolina and Connecticut, disallow the gambling-loss deduction outright, so you can owe state tax on gross winnings with no offset at all even when your federal return shows a deduction. This calculator stays federal for that reason: a generic state rate applied to federal taxable income would be confidently wrong for exactly the bettors who need the answer most.

Professional gamblers, meaning those who gamble as a trade or business under the Groetzinger standard, file Schedule C and owe self-employment tax. The amended Section 165(d) did not leave them alone: it expanded losses from wagering transactions to include any otherwise allowable deduction incurred in carrying on a wagering transaction, which pulls travel, data subscriptions and entry fees inside the same 90%-of-losses, capped-at-winnings limit. This calculator models a casual or recreational gambler.
