If you walked into a casino last year, broke even, and walked out – congratulations, you owed nothing in gambling taxes. That was the deal for decades: you could deduct 100% of your gambling losses against your winnings, and a break-even night meant zero taxable gambling income.
That deal changed on July 4, 2025.
The One Big Beautiful Bill Act (OBBBA), signed into law as part of a sweeping fiscal package, quietly introduced a provision that most casual gamblers have not yet heard about: a 90% cap on gambling loss deductions. The change sounds minor – 90% versus 100% – until you do the math. And the math creates a concept that tax professionals are calling “phantom income.”
What Actually Changed
Before 2026, gambling taxation worked on a simple principle. You reported all gambling winnings as income on your federal return. If you itemized deductions, you could deduct gambling losses up to the amount of your winnings. Win $10,000 and lose $10,000? Net taxable gambling income: zero.
Under the new law, you can only deduct 90% of your gambling losses. Same scenario – win $10,000, lose $10,000 – now looks different. You report $10,000 in winnings. You deduct 90% of your $10,000 in losses, which is $9,000. Net taxable gambling income: $1,000.
That $1,000 is phantom income. You never actually earned it. You broke even. But the IRS treats it as taxable income, and depending on your tax bracket, you could owe $120 to $370 in federal taxes on money you never made.
The Impact Scales with Volume
The 90% cap hits hardest on high-volume recreational gamblers. A poker player who grinds low-stakes tournaments and finishes the year with $50,000 in cashes and $50,000 in buy-ins has $5,000 in phantom income. At the 22% bracket, that is $1,100 in taxes on what was effectively a break-even year.
Sports bettors face similar math. A bettor who wagers $200,000 over the course of a year – not unusual for someone placing regular bets through legal sportsbooks – and breaks even after the vig will owe taxes on 10% of their total losses. The more you play, the more the cap costs you, even if you never come out ahead.
Who Is Affected – and Who Is Not
The 90% cap applies specifically to casual gamblers – the IRS classification for anyone who gambles but does not qualify as a professional gambler under Section 162.
Casual Gamblers
If you gamble recreationally, you are a casual gambler in the eyes of the IRS. This includes:
- Weekend casino visitors
- Fantasy sports and sports betting enthusiasts
- Recreational poker players
- Lottery and scratch-off buyers
For casual gamblers, the new cap means that itemizing gambling losses – already a requirement for any deduction – now leaves 10% of those losses permanently non-deductible. If you take the standard deduction ($15,000 for single filers in 2026), you cannot deduct any gambling losses at all, making the 90% cap irrelevant but your tax situation potentially worse.
Professional Gamblers
Professional gamblers – those who can demonstrate that gambling is their primary trade or business, with regular hours, detailed records, and a genuine profit motive – report their income and expenses on Schedule C. The OBBBA’s 90% cap does not apply to Schedule C filers. Professionals can still deduct 100% of their gambling losses as business expenses.
The irony is stark. The provision was marketed as closing a loophole for wealthy gamblers, but it primarily affects middle-income recreational players who happen to itemize their deductions. Professional gamblers, who typically have the highest volume and the most to deduct, are exempt.
W-2G Reporting and the Compliance Trap
The 90% cap intersects awkwardly with W-2G reporting thresholds. Casinos and sportsbooks are required to issue a W-2G form – and report the winnings to the IRS – when payouts exceed certain thresholds:
- Slot machines and bingo: $1,200 or more
- Keno: $1,500 or more
- Poker tournaments: $5,000 or more (net of buy-in)
- Sports betting: $600 or more at 300:1 odds or greater
When a W-2G is issued, the IRS knows about the winning. What the IRS does not automatically know about is the corresponding losses. This has always created an asymmetry – the government sees your wins but not your losses – and the 90% cap makes that asymmetry more expensive.
A slot player who hits a $5,000 jackpot and has lost $5,000 over the course of the year previously owed nothing (assuming they itemized). Now they owe tax on $500 of phantom income. And if they do not itemize – if they take the standard deduction – they owe tax on the full $5,000, as has always been the case.
Understanding these thresholds and how the IRS gambling losses 90% rule interacts with your specific situation is critical for anyone who gambles regularly in 2026.
The Full House Act: A Counter-Proposal
Not everyone in Congress agrees with the 90% cap. Representatives Dina Titus (D-NV) and Guy Reschenthaler (R-PA) introduced the Full House Act, a bipartisan bill that would repeal the 90% cap and restore the full deduction.
The bill’s sponsors argue that the cap creates an unfair tax on recreation. Their position is straightforward: if a gambler breaks even, they should not owe taxes. The American Gaming Association has endorsed the bill, noting that the cap disproportionately burdens the 51 million Americans who visit casinos annually.
As of early 2026, the Full House Act is in committee. Its passage is uncertain, but the bipartisan support is notable. Nevada’s congressional delegation, unsurprisingly, is unanimously behind it.
Practical Tips for 2026
The new tax landscape requires casual gamblers to be more deliberate about record-keeping and tax planning.
Keep Meticulous Records
The IRS requires a contemporaneous log of gambling activity to claim any loss deduction. This includes the date, location, type of game, amounts wagered, and amounts won or lost. Save W-2Gs, losing tickets, and sportsbook transaction histories. If you are audited, the burden of proof is on you.
Run the Numbers Before Filing
Before filing your 2026 return, calculate whether itemizing – with the 90% cap – saves you more than the standard deduction. For many recreational gamblers, the standard deduction will still be the better choice, meaning the 90% cap is a secondary concern behind the larger question of whether to itemize at all.
Consider a Gambling Tax Calculator
Tools like the gambling tax calculators available on ToolsGambling can help you estimate your effective tax rate under the new rules. Input your total winnings, total losses, filing status, and state of residence to see what you will actually owe. This is especially useful for gamblers in states with their own loss-deduction rules.
Track Wins and Losses by Game Type
Since W-2G thresholds vary by game, tracking results separately for slots, poker, sports betting, and table games can help you and your tax preparer apply the deductions correctly. A single annual total is less useful than a breakdown by category.
The Bottom Line
The 90% gambling loss deduction cap is not a catastrophic change for most recreational gamblers – but it is a meaningful one for anyone who gambles frequently and itemizes deductions. The creation of phantom income on break-even gambling is a genuine policy oddity, and the Full House Act may eventually repeal it.
In the meantime, the practical response is straightforward: keep records, understand your state’s rules, use a tax calculator to estimate your liability, and make filing decisions based on the math rather than assumptions. The tax code has always treated gambling income asymmetrically. The 2026 changes simply made that asymmetry slightly more expensive.
