Sports betting taxes in 2026, from the single bet to the season
A sportsbook account can show a loss for the year and still leave tax to pay in 2026. Here is how the federal rules read a season of bets.
- W-2G only if
- $2,000 and 300x the stake
- Withholding
- 24 % of proceeds over $5,000
- Losses deductible
- 90 %, itemizers only
Tax on the 2026 gambling result
$2,486
Net result -$2,000. Under the 2025 rule the federal tax would have been $902; the 90 % limit adds $264.
| Losses deductible in 2026 (90 %, up to winnings) | $28,800 |
| Losses that no longer count | $1,200 |
| Itemizing beats the standard deduction | yes |
| Federal tax on the gambling | $1,166 |
| Colorado tax on the gambling | $1,320 |
| Federal tax under the 2025 rule | $902 |
Colorado taxes the winnings without the losses in this case. Losses count only for those who itemize; without itemizing, every dollar won is taxed.

Winnings from sports bets are taxable income in 2026 at the ordinary federal brackets, on Schedule 1 of Form 1040, whatever the size of the bet and whether or not a form arrives. Most winning bets never produce a Form W-2G, because the payout must reach $2,000 and be at least 300 times the stake: a $2,400 return on a $1,000 bet brings no form, while a $7,500 parlay on a $20 stake does and has $1,795 withheld, 24 % of the proceeds. Losses offset winnings only for bettors who itemize and, from 2026, only at 90 % of their amount. A Colorado bettor with $30,000 of winnings and $32,000 of losses, single with an $85,000 salary, ends the year behind yet owes $1,166 of federal tax on the betting, where the 2025 rule gave $902. The state adds $1,320.

Two totals for the year
The federal return does not look at bets one by one. It asks for the year's gambling winnings, added to income on Schedule 1, and, for those who itemize, the year's wagering losses as an "other itemized deduction" on Schedule A (IRS Topic no. 419). A sportsbook's annual win and loss statement and the account history are the natural records for both totals. Bettors who use several apps keep each history, because the totals cover every account and every in-person bet.
The gap between those two totals is where 2026 differs. Before, a bettor who itemized could subtract the full losses up to the winnings. Since section 70114 of Public Law 119-21, only 90 % of the losses are deductible, still capped at the winnings. A season with heavy volume and a thin result is now taxed on more than its result.
Three bettors, three outcomes
| Bettor | Net result | Losses deducted | Federal tax on betting | Colorado tax on betting |
|---|---|---|---|---|
| Casual: won $4,000, lost $3,500 | $500 | none (standard deduction) | $880 | $176 |
| Volume, behind: won $30,000, lost $32,000 | -$2,000 | $28,800 | $1,166 | $1,320 |
| Volume, ahead: won $30,000, lost $18,000 | $12,000 | $16,200 | $3,938 | $1,320 |
The casual bettor is the most common case and the least intuitive. Up $500 on the year, they pay tax on all $4,000 of winnings, because $3,150 of deductible losses would not lift their itemized deductions above the standard deduction of $16,100. The bettor who finished $2,000 behind is taxed on $1,200 of losses that the new limit no longer lets in; the one who finished ahead is taxed on the gain and on a tenth of the losses. The 90 percent rule sets out the arithmetic for any year.
When the sportsbook files a W-2G
For sports wagering, the instructions say to file Form W-2G "if the winnings are at least 300 times the amount of the wager" and meet the reporting threshold, $2,000 for payments made in 2026 (Instructions for Forms W-2G and 5754). Straight bets at ordinary odds never reach that multiple, so the $2,400 return on a $1,000 bet is not reported. Long-odds parlays, futures and some promotions can: the $7,500 parlay on a $20 stake is 375 times the stake.
The same test opens the door to withholding. When the proceeds, the winnings minus the wager, exceed $5,000 and the multiple is met, the book withholds 24 % of the proceeds and shows it in box 4. Form W-2G in 2026 details the other boxes. Everything else, the steady flow of small and medium wins, is reported by the bettor alone.
The state side of a bet
A resident is taxed by the home state on gambling winnings from anywhere, with each state deciding how losses count. The Colorado column taxes the full winnings: Colorado starts from federal taxable income, but the official Colorado sources read for this site do not confirm how gambling losses enter the state return, so no state deduction is assumed. Some states also tax a nonresident on wagers placed within their borders. Massachusetts, for one, lists "any other wagering transaction within MA" among the winnings of nonresidents it taxes (Mass. DOR, gambling and the lottery). A credit at home usually follows; the credit for taxes paid to another state explains its limit.
Which year a bet belongs to
A win counts in the year it is paid or credited without restriction. The W-2G instructions describe a payment as made when it is "credited to or set apart for that person without any substantial limitation" on its withdrawal. A futures bet placed in the fall of 2026 and settled after the final in 2027 is 2027 income, and its stake, if it loses, is a 2027 loss. Married bettors who file jointly add both spouses' winnings and both spouses' losses; the IRS proposed rules of IRB 2026-19 adjust that combination to the 90 % limit.
Estimated tax and records
Because so little is withheld on sports bets, a profitable season can leave a large balance in April. The IRS points bettors to estimated tax payments and Publication 505 for that. These figures are estimates under the 2026 rules, not tax advice for any return. Betting is a paid pastime, not a source of income; anyone who feels it slipping from that can reach the National Problem Gambling Helpline, free and confidential, at 1-800-MY-RESET (NCPG).
