A New Era of Tax Reform for Gamblers
The Tax Cuts and Jobs Act (TCJA) of 2017 was the first major rewrite of how the IRS treats gambling income and losses. Now, nearly a decade later, the One Big Beautiful Bill Act (OBBB) of 2026 takes it a step further. While the bill runs hundreds of pages, one small section — Section 70114 — quietly changes the game for gamblers across America. It redefines what counts as a deductible ‘loss,’ limits those deductions to 90 percent of winnings, and makes permanent the TCJA rule that business expenses count as part of the same limitation.
A New “Hidden Tax” Comes to Light
The One Big Beautiful Bill Act (OBBB) may sound charming by name, but for gamblers—professional or casual—it’s anything but beautiful. Starting January 1, 2026, the new rule under the amended Internal Revenue Code §165(d) introduces what’s being called the “90 % rule.” That means you will only be able to deduct 90 percent of your total gambling losses and expenses—and still only up to the amount of your winnings. The remaining 10 percent becomes taxable income, even if you lost money overall. This is the textbook definition of phantom income—income that exists only for tax purposes, not in reality.
How Phantom Income Works
Let’s look at a simple example.
A gambler walks into a casino with $2,000 in cash. After a long session of slot play:
– The gambler hits multiple jackpots totaling $35,000, each reported on Form W-2G.
– They keep playing, and eventually lose everything—including the original $2,000.
On paper, the gambler has $35,000 of gross winnings. Under the 2026 rule, they may only deduct 90 % of those losses and expenses. That means 10 % of $35,000 = $3,500 will count as taxable income—even though the player walked out broke. This $3,500 doesn’t exist in the gambler’s pocket—it exists only in the IRS’s eyes. That’s phantom income.
Why It Matters
Until now, gamblers could fully offset their winnings with losses (up to 100 %), leaving little or no taxable income if they broke even. The OBBB Act changes that balance:
– Even if you lose all your winnings, you’ll owe tax on 10 percent of the total jackpots reported.
– This affects both casual players and professional gamblers alike.
– It will especially hit high rollers and regular slot players who accumulate hundreds of thousands of dollars reported in W-2Gs jackpots through progressive winnings.
If a professional player ends the year with $1 million in W-2Gs, even if they lost the same amount, $100,000 will now be added to their Adjusted Gross Income (AGI) starting in 2026. That’s a massive change for anyone playing regularly—and a major revenue boost for the IRS.
Impact on Tribal Casinos
Oklahoma and other tribal gaming states could see a wave of discontent once players realize that their “wins” are taxable even when they walk away losing. “High rollers” may scale back their play or take replace the gambling with something else, while small and occasional players continue unaffected. The result? A potential dip in casino revenue, particularly in markets that rely heavily on repeat progressive slot players.
What Gamblers Should Do Now
1. Track every wager — Keep a detailed gambling log.
2. Expect higher tax bills — Plan for at least 10 percent of total W-2G winnings to become taxable.
3. Set aside funds — High-stakes players should save extra for 2026 tax liability.
4. Talk to a tax professional — Your preparer will help you plan for this change, especially if you play frequently or hold multiple W-2Gs.
5. Reconsider gambling patterns — If the fun no longer outweighs the tax cost, it may be time to re-evaluate.
Final Thoughts
For years, there’s been an invisible tax on gambling: the hidden cost of gambling through increased taxes due to modified adjusted gross income. In other words, because of higher AGI, some people paid more taxes even when they were deducting the losses in full. In 2026, that hidden tax becomes visible. The OBBB Act may be “beautiful” for federal revenue—but for gamblers, it’s a new kind of jackpot: one that the IRS always wins. 🙂
So, play for fun or play for business —but know the new rules before you press that spin button.
