A significant gambling tax change takes effect for the 2026 tax year, limiting how much bettors can deduct in losses. Under the new rule, gamblers who itemize can deduct losses only up to 90 percent of their winnings, a shift that could leave many players owing tax on money they never actually pocketed. Here is what you need to know.
In short: starting with the 2026 tax year, itemizing gamblers can deduct losses only up to 90 percent of winnings, down from 100 percent. This creates "phantom income," meaning even break-even bettors can owe tax. The change does not affect 2025 returns. This is general information, not personalized tax advice.
What the New Rule Changes
For decades, gamblers who itemized could deduct losses up to the full amount of their winnings, meaning a player who broke even owed no federal tax on gambling activity. Starting with the 2026 tax year, that deduction is capped at 90 percent of winnings. The change does not affect tax returns filed for income earned in 2025, so it applies going forward. This is general information rather than tax advice, and bettors with significant activity should consult a qualified tax professional.
Understanding Phantom Income
The most important consequence of the new rule is what some call phantom income. Because only 90 percent of losses can offset winnings, a bettor who wins and loses the same amount over a year still shows taxable income. For example, a player who wins $100,000 and loses $100,000 has broken even in reality, but can deduct only $90,000 in losses, leaving $10,000 in taxable income despite no actual profit. High-volume bettors feel this effect most acutely.
Who Is Affected Most?
The rule hits high-volume players hardest, including professional gamblers, advantage players, and recreational bettors who place large numbers of wagers. Because winnings and losses are tracked on a gross basis, even break-even players who churn significant action can accumulate large reported winnings. Casual bettors who wager modest amounts and rarely itemize may see little change, but anyone with substantial annual volume should pay close attention.
How Prediction Markets Complicate the Picture
The tax landscape grew more complex in 2026 as prediction markets surged. Platforms offering event contracts are regulated federally as derivatives rather than as sports betting, which can lead to different tax treatment than traditional sportsbook wagers. This patchwork creates confusion for bettors who use multiple platforms, and it is one reason the broader regulatory debate over prediction markets has intensified.

State-Level Tax Considerations
Federal rules are only part of the picture. State tax treatment of gambling winnings varies widely, and some states do not allow any deduction for gambling losses at all, meaning residents there already face a version of phantom-income taxation. A handful of states impose no income tax, while others tax winnings at high rates with little or no offset for losses. Bettors who play across state lines, whether at physical casinos or through mobile apps, may face filing obligations in multiple states. The interaction between the new federal 90 percent cap and existing state rules can compound a bettor's liability in unexpected ways. Anyone with meaningful gambling activity should understand both their federal and state obligations, and should strongly consider working with a tax professional who specializes in gaming income to navigate the layers correctly.
Steps Bettors Can Take Now
Preparation is the best defense against an unexpected tax bill. Bettors should keep meticulous records of every wager, including dates, amounts, platforms, and outcomes. Many sportsbooks and casinos provide annual win-loss statements that help, but personal records add an important layer of accuracy. Setting aside a portion of winnings for potential taxes throughout the year can prevent a painful surprise at filing time.
Why This Matters for the Industry
Industry groups have warned that the change could push high-volume players toward unregulated or offshore platforms that operate outside the tax system, potentially undermining the legal market that states have worked to build. The debate touches on the same themes driving regulatory fights over prediction markets and tax revenue, underscoring how tax policy shapes where and how people bet.

The Bigger Regulatory Context
The 90 percent rule arrives amid a broader reckoning over how gambling is taxed in the United States. As legal betting has expanded across dozens of states, lawmakers have looked for new revenue, while the rise of federally regulated prediction markets has created gaps that states say cost them more than $1 billion annually. Tax policy is now a central front in the fight over the future of American gambling. Advocacy groups representing professional and recreational players have pushed back against the loss-deduction change, arguing that it taxes income that does not really exist and unfairly penalizes the highest-volume, most skilled players. Whether lawmakers revisit the provision in future sessions remains to be seen, but for now bettors must plan around the rule as written. The takeaway for anyone with meaningful gambling activity is to treat tax planning as an integral part of their overall strategy rather than an afterthought handled only at filing time. Proactive record-keeping and professional guidance are the best protection against an unwelcome surprise.
