Congress just made gambling more expensive. Buried in the One Big Beautiful Bill Act is a provision that cuts your gambling loss deduction from 100% to 90%, creating what tax professionals are calling "phantom income."

Starting January 1, 2026, you'll pay taxes on money you never actually kept.

The Quick Hit

• The change: Gambling loss deduction drops from 100% to 90%
• Effective date: January 1, 2026
• The problem: Creates taxable "phantom income" on the 10% you can't deduct
• Who's hurt: High-volume bettors who churn significant amounts
• The fix attempt: FAIR BET Act proposed to restore full deduction

How It Works (And Why It Hurts)

Under current IRS rules, you can deduct gambling losses up to the amount of your winnings. If you win $100,000 and lose $100,000, you're even — no taxable gambling income.

Under the new law, you can only deduct 90% of your losses. Same scenario: win $100,000, lose $100,000, but now you can only deduct $90,000 in losses. The IRS treats you as having $10,000 in taxable gambling income.

That's $10,000 you never had. You broke even. But the government says you owe taxes on phantom winnings.

Who Gets Destroyed

Casual bettors who put $50 on a few NFL games won't notice. The math doesn't move much at small stakes.

But high-volume bettors — the people churning serious money through sportsbooks — are looking at significant new tax liability on income that doesn't exist.

Professional gamblers, sharp bettors with high turnover, and anyone who plays a lot of hands of poker or spins on slots could find themselves owing thousands in taxes despite breaking even or losing money for the year.

The Reaction

House Ways and Means Committee Chairman Jason Smith called the provision a "mistake." That's notable — it's rare for a committee chairman to publicly criticize a bill his own party passed.

Representative Dina Titus of Nevada introduced the FAIR BET Act to restore the full 100% deduction. Nevada's entire congressional delegation is expected to support it. Whether it passes is another question.

The casino industry is pushing hard for repeal. Derek Stevens, Bill Hornbuckle, Tom Reeg, and Craig Billings — the CEOs of Circa, MGM, Caesars, and Wynn respectively — met with Smith last week to lobby for restoration of the full deduction.

The Bigger Tax Picture

This isn't the only gambling tax change happening. The IRS also confirmed that the slot jackpot reporting threshold will increase from $1,200 to $2,000 starting in 2026. That's actually good news for slot players — fewer mandatory tax forms.

But the loss deduction change more than offsets any benefit for serious gamblers.

What You Can Do

Not much, honestly. The law is the law starting January 1, 2026.

If you're a high-volume bettor, you might want to:

• Track your wins and losses meticulously
• Consider the tax implications before placing large wagers
• Talk to a tax professional about your specific situation
• Hope the FAIR BET Act passes (don't hold your breath)

The Bottom Line

Congress managed to create a tax on money you didn't make. Win $500K, lose $500K, owe taxes on $50K of phantom income. That's the new reality for anyone betting serious money in 2026. Merry Christmas from Washington.
