The rule comes from the One Big Beautiful Bill Act, which amended Section 165(d) of the tax code. It took effect on January 1, 2026, and it was made permanent, with no sunset date. For decades, a bettor who itemised could deduct losses up to the amount of winnings, dollar for dollar. Now the deduction is capped at 90% of losses. ## How the math works The cap bites when your losses are close to, or below, your winnings. Two examples show it. - **Break even.** You wager and win 1,000,000 dollars over the year and lose 1,000,000 dollars. Net profit: zero. Your deductible losses are now 900,000 dollars, so 100,000 dollars becomes taxable. At a 37% rate that is roughly 37,000 dollars owed on no real gain, per an [analysis from the Tax Foundation](https://taxfoundation.org/blog/gambling-losses-tax-big-beautiful-bill/?ref=igamingnews.biz). - **Matched year.** You win 4,000 dollars and lose 4,000 dollars. You can deduct 3,600 dollars, leaving 400 dollars taxable, again on zero net profit. Winners lose ground too. If you win more than you lose, you now pay tax on an extra 10% of your losing wagers, because only 90% of them offset your wins. One group is untouched: bettors who lose far more than they win. If your losses run well above your winnings, your deduction was already capped at your winnings, so the 90% rule changes nothing for you. The tax falls on the winners and the break-even grinders, not the heavy losers. ## Who actually gets hit The change matters most to a specific set of bettors. - **High-volume players.** Advantage players, sharp sports bettors, daily fantasy grinders and professional gamblers churn huge sums to net small margins. On a million dollars of turnover, a 10% disallowance is a large phantom number. - **Itemisers.** The loss deduction only exists for bettors who itemise. Casual bettors who take the standard deduction get no loss deduction at all, which was true before and stays true now. - **Anyone with a big win.** A jackpot or a good year that triggers a W-2G puts winnings on the record. Losses have always needed proof; now 10% of them will not count anyway. The Joint Committee on Taxation estimated the provision raises more than 1.1 billion dollars over eight years. That number is the measure of what comes out of bettors' pockets. ## What bettors should do The change rewards record-keeping and punishes sloppiness. **Track by session, not by year.** Log wins and losses with dates, venues and amounts. The IRS expects contemporaneous records, and the new cap makes the loss figure worth defending precisely. **Know your state adds to this.** State tax treatment of gambling varies, and some states allow no loss deduction at all. The federal cap sits on top of whatever your state already does. **Factor it into your edge.** If you bet for profit, the after-tax return on high-turnover play just dropped. The break-even point moved against you. There is a political footnote. Lawmakers have introduced bills to restore the full 100% deduction, and industry and player groups are pushing hard, but nothing has passed. For the 2026 tax year, plan around the 90% rule as written. ## The tax lands on volume, not profit This is part of a wider squeeze on gambling economics. Operators are already absorbing [higher betting taxes](https://www.igamingnews.biz/us-sports-betting-tax-operator-economics/) and [pulling back promotional spending](https://www.igamingnews.biz/sportsbook-promotional-spending-tax/) as states raise rates. Now the bettor carries a direct federal cost too, tied not to how much they win but to how much they wager. The uncomfortable part is the principle. A tax that can turn a break-even year into a taxable one is a tax on activity, not on income. Until Congress changes it, the safest move for any serious bettor is to keep clean records, understand the after-tax math before betting, and use the deposit limits and self-exclusion tools that keep turnover in check.
