The OBBBA gambling loss deduction change is one of the sneakiest IRS moves yet. Buried in the One Big Beautiful Bill Act (OBBBA), it creates serious headaches for gamblers across the country.
Starting in 2026, both casual and professional gamblers will be limited to deducting only 90% of their gambling losses. That leftover 10%? Gone. Not deductible. Forever lost.
Let’s break this down in real terms:
Say you hit a few lucky weekends and win $18,000. You also lost $18,000—but thanks to the new rules, you can only deduct 90% of those losses. That’s $16,200.
Which means you now owe taxes on $1,800 of fictional income—despite breaking even in reality.
Yes. It’s real. And yes—it’s absurd.
Example: Brian the Casual Gambler
Brian won $18,000 playing roulette over a few weekends. He also lost $18,000. Under the old rules, he could deduct the full $18K and pay zero tax. But in 2026? He can only deduct 90% of his losses—so he ends up with $1,800 of taxable income.
You’re in the game full-time. You win $700K. Lose $560K. Rack up $70K in travel and other gambling-related business expenses.
Before? You could deduct all of it.
Now? You’re capped at 90% of your combined losses and expenses. That’s $630K x 90% = $567K.
You’re now paying taxes on $133K, even though you didn’t pocket that much at all.
Example: Jasmine the Poker Pro
Jasmine had a rollercoaster year—won $700,000, lost $560,000, and spent $70,000 on travel, lodging, and tournament fees. Before, she would’ve reported $0 in net income. But now, the IRS lets her deduct only $567,000 (90% of $630,000), leaving her with $133,000 in taxable income. That’s not just painful—that’s fiction.
Gamblers are furious—and rightfully so. Some are even threatening to renounce citizenship if this goes through.
And guess what? Congress might actually listen.
Lawmakers are already scrambling to undo the damage. Multiple bipartisan bills are on the table to kill the 10% haircut and roll back to the previous deduction rules. But until something passes, it’s game on.
Don’t bet on Congress moving fast.
Example: The Slot Machine Trap
You win $1,200 on a single spin. The casino issues a Form W-2G and sends it to the IRS. But by the time your session ends, you've lost that $1,200—and then some. Your actual gambling session was a loss, but the IRS sees a $1,200 gain unless you explain otherwise.
The OBBBA gambling loss deduction cap applies starting with the 2026 tax year (returns you file in 2027). Plan now so you’re not surprised by “phantom income.”
Both. Casual gamblers are limited to deducting only 90% of their losses (still only up to the amount of winnings). Professional gamblers are also limited: their wagering losses plus related gambling business expenses are grouped and capped at 90%, still limited to total gambling winnings.
No. The disallowed 10% is simply non-deductible. It doesn’t carry forward and can’t be used to increase deductions in a later year.
W-2G forms report specific jackpots or thresholds (e.g., many slots at $1,200). On your return, you should report your actual results—which for many games is tracked by gambling sessions—and keep detailed records. If your session records don’t match the sum of your W-2Gs, you can disclose and explain the difference in your workpapers and, if appropriate, with a Form 8275 disclosure to reduce penalty risk.
Maintain a contemporaneous gambling log: dates, locations, games, amounts won/lost, and supporting documents (receipts, tickets, player card statements, bank/ATM records, etc.). See the IRS guidance on gambling recordkeeping here: IRS Topic No. 419—Gambling Income & Losses.
No. Gambling losses are deductible only up to gambling winnings, and the OBBBA 90% cap further limits the deduction. You can’t use gambling losses to create or increase an NOL.
Under OBBBA, allowable gambling business expenses (like travel, lodging, tournament fees) are aggregated with wagering losses and then subject to the 90% cap, still limited to total gambling winnings. Precise tracking and categorization are critical.
It depends. Some states conform closely to federal changes; others don’t. Check your state’s conformity rules and plan for differences between federal and state returns.
Yes—if you gamble. Because 10% of losses becomes non-deductible, you can end up with taxable income even when you’re break-even on cash. Update your estimates/withholding so you’re not underpaid.
Generally, gambling income is taxable. Promo credits/free play can still produce taxable winnings when redeemed, and comps may have tax implications. Record these items carefully in your session logs and keep any casino statements to support your numbers.
This is more than a tax change. It’s a shift toward taxing phantom profits—and it sets a dangerous precedent.
Whether you gamble occasionally or it’s your profession, you need to protect yourself. Now.
