Gambling Losses 90% Deduction Limit 2026: The OBBBA Rule

This article is for educational purposes only and is not tax, legal, or financial advice. Tax rules change, and gambling deductions are frequently challenged by the IRS, so always check current IRS guidance or consult a qualified tax professional before filing.

For the first time, you can lose money gambling and still owe tax on it. Starting in 2026, you can only deduct 90% of your gambling losses, not the full 100%. That small-sounding change quietly creates a tax bill for people who broke even, and a bigger one for high-volume players.

This guide walks through exactly how the new cap works, with the math competitors only describe in words. We cover break-even, net-loss, and high-stakes examples, the itemize requirement that trips up casual bettors, what records you need, and whether Congress is likely to undo it.

What Changed: The 90% Gambling Loss Cap for 2026

The One Big Beautiful Bill Act (P.L. 119-21), signed into law on July 4, 2025, amended IRC Section 165(d). The gambling provision sits in Section 70114 of the Act.

Before 2026, you could deduct gambling losses dollar-for-dollar, up to the amount of your winnings. Win $5,000, lose $5,000, and you could deduct the full $5,000 and owe nothing.

Now the deduction is capped at 90% of your losses. The rule takes effect for tax years beginning after December 31, 2025, so it first hits the 2026 return you file in early 2027.

Three older limits still apply on top of the new haircut:

Your loss deduction can never exceed your total gambling winnings.
You can only claim losses if you itemize (more on that below).
Losses can only offset gambling winnings, never wages or other income, and there is no carryforward.

The Joint Committee on Taxation estimated the change raises roughly $1.1 billion in federal revenue. That revenue comes directly out of the pockets of gamblers who previously owed nothing on break-even years.

How the 90% Limit Works (With Real Examples)

The cleanest way to understand the cap is to run actual numbers. Each example assumes the taxpayer itemizes, since that is required to claim any loss at all.

Break-Even Example: Win $10,000, Lose $10,000

You report $10,000 in gambling winnings. You also have $10,000 in documented losses.

Deductible losses: 90% of $10,000 = $9,000
Taxable gambling income: $10,000 winnings - $9,000 deduction = $1,000

You broke even on the felt, but you now owe tax on $1,000. In the 22% bracket, that is roughly $220 of tax on money you never actually kept.

Net-Loss Example: Win $10,000, Lose $12,000

You had a losing year. You won $10,000 but lost $12,000.

The deduction is capped at your winnings, so first it cannot exceed $10,000.
90% of your $12,000 in losses is $10,800, but the winnings cap holds it to $10,000.
Both limits stack: your deduction is the lesser of 90% of losses or 100% of winnings. Here that is $10,000.

So you deduct $10,000 against $10,000 in winnings and owe no gambling tax this year. The extra $2,000 you genuinely lost is gone, though. It does not carry forward, and it cannot reduce your wages.

Partial Example: Win $7,500, Lose $10,000

You won $7,500 but lost $10,000 chasing it.

90% of your $10,000 in losses is $9,000.
But the deduction cannot exceed your $7,500 in winnings.
Deductible amount: $7,500 (the winnings cap binds first).

Your gambling income nets to zero, while $2,500 of real losses vanishes with no future benefit.

High-Stakes Example: Win $250,000, Lose $250,000

This is where the cap bites hardest. A serious player reports $250,000 in winnings and $250,000 in losses.

Deductible losses: 90% of $250,000 = $225,000
Taxable gambling income: $250,000 - $225,000 = $25,000

A perfectly break-even year now produces $25,000 of taxable income. At a 35% marginal rate, that is roughly $8,750 owed on a year where the player made no profit.

”Phantom Income”: Why Break-Even Gamblers Now Owe Tax

Phantom income is income you owe tax on without having any real economic gain. The 90% cap manufactures it.

Here is the mechanism. You report 100% of your winnings as income, but you can only deduct 90% of your losses. In a break-even year, that gap, the missing 10% of your losses, becomes taxable.

The bigger your gross activity, the bigger the phantom income. A player who cycles $1 million through wins and $1 million through losses ends up with $100,000 of taxable phantom income, despite a net result of zero.

Three details make it worse:

No carryforward. Unused losses do not roll to next year the way capital losses do.
No cross-offset. Gambling losses only touch gambling winnings. They cannot reduce your salary, business income, or investment gains.
Gross, not net. Because winnings and losses are reported separately, high-volume play inflates both sides and magnifies the 10% gap.

Who Is Affected: Casual vs. Professional Gamblers

The cap reaches both casual and professional gamblers, but the mechanics differ.

Casual gamblers must itemize

This is the point most people miss. A casual gambler can only deduct losses as an itemized deduction on Schedule A. If you take the standard deduction (and roughly 9 in 10 filers do), you get no offset for losses at all.

So a recreational bettor taking the standard deduction reports 100% of winnings as income and deducts zero losses. The 90% cap is almost a side issue for them, because the itemize gate already blocks the deduction entirely.

If you do itemize, your gambling losses join your other Schedule A items, and the 90% cap applies to the loss figure you claim.

Professional gamblers report on Schedule C

A professional gambler (someone gambling as a trade or business) reports on Schedule C and does not need to itemize to deduct losses. The OBBBA change reaches them too.

Under the amended Section 165(d), a professional’s wagering losses plus related business expenses (travel, data services, tournament fees) are grouped together and limited to 90% of winnings. So the 10% haircut now applies to legitimate business expenses, not just losing bets, a nuance many summaries skip.

What You Must Do to Claim the Deduction in 2026

If you want to claim every dollar the law allows, documentation is everything. The IRS challenges gambling deductions often, and the burden of proof is on you.

Itemize on Schedule A

Casual gamblers must itemize. Before assuming you can deduct anything, confirm your total itemized deductions exceed your standard deduction. Our 2026 federal tax brackets guide walks through the standard deduction amounts and when itemizing makes sense.

Keep a contemporaneous gambling log

IRS Topic 419 expects a running record kept at the time you play, not reconstructed at tax time. A defensible log includes:

Dates and locations of each session
Type of wager or game
Amounts won and amounts lost
Names of any other people present (for table games)

Back it up with W-2Gs, betting slips, casino player-card statements, and bank or app records.

Use the session method

You do not have to record every single hand or spin. The session method lets you net your wins and losses within one continuous session at the same establishment. You record the net result of each session rather than each bet, which is both simpler and what the IRS expects.

Watch the 2026 W-2G threshold

The 2026 W-2G instructions reference a $2,000 reporting threshold for certain payouts. More activity will generate paperwork, and the IRS receives copies, so the winnings side of your return is increasingly hard to under-report.

You can model how these winnings and the 90% loss cap flow onto a return in Tax47, which applies the 2026 OBBBA changes automatically when you assemble a return from real W-2G and winnings data. Seeing the phantom income land as taxable income before you file beats discovering it in April.

Will It Be Repealed? FAIR BET and FULL HOUSE Act Status

The 90% cap drew immediate pushback, and two bills aim to restore the full 100% deduction.

The FAIR BET Act would reverse the change and return to dollar-for-dollar loss deductions.
The FULL HOUSE Act is a parallel effort with the same goal.

As of early 2026, both have stalled. The House Rules Committee declined to advance the FAIR BET Act as an amendment to the 2026 National Defense Authorization Act, and neither bill has cleared a path to passage.

Here is the honest planning advice. Assume the cap applies. Legislative repeal is possible but far from certain, and you cannot file a 2026 return on the hope of a future law change. If a repeal passes later, you adjust then.

State Conformity and Planning Takeaways

The federal cap is only part of the picture. State treatment can make the hit worse.

Many states do not allow a gambling-loss deduction at all. In those states, you may owe state tax on 100% of your winnings with zero loss offset, regardless of what you can claim federally. A break-even year can produce a federal tax bill and a separate, larger state bill.

A few practical takeaways:

Check whether itemizing even helps you. If the standard deduction wins, your losses are not deductible federally no matter how careful your records are.
Track gross activity, not just net. High-volume low-edge play (sports parlays, daily fantasy, slots) inflates both winnings and losses and maximizes the 10% phantom-income gap.
Look up your state’s rule before assuming a break-even year is tax-free.
Run the numbers before you file. You can compare a break-even scenario against a net-loss scenario in Tax47 and see the actual tax impact, then explore other tax tools to round out your return.

The 90% cap is a quiet rule with a loud effect. It taxes activity, not profit. Knowing how it lands on your return is the difference between an unwelcome surprise and a planned-for number.

Frequently Asked Questions

How much of my gambling losses can I deduct in 2026?

Up to 90% of your documented losses, and only up to the amount of gambling winnings you report. The 10% you can no longer deduct disappears, and your losses can never exceed your winnings.

What is phantom income from gambling?

Phantom income is taxable income created when you break even but can only deduct 90% of your losses. The disallowed 10% leaves a slice of your reported winnings taxed even though you made no real profit.

Do I have to itemize to deduct gambling losses?

Yes. Casual gamblers can only claim losses as an itemized deduction on Schedule A. If you take the standard deduction, you get no offset for your gambling losses at all.

Does the 90% cap apply to professional gamblers too?

Yes. Professional gamblers report on Schedule C, but their wagering losses plus related gambling business expenses are grouped under Section 165(d) and still limited to 90% of winnings.

Can I carry forward gambling losses I cannot deduct?

No. Excess losses, including the disallowed 10%, do not carry forward to future years and cannot offset wages or any other type of income.

When does the 90% gambling loss limit take effect?

It applies to tax years beginning after December 31, 2025, which means the 2026 tax year (returns filed in early 2027). Tax year 2025 returns still use the old 100% rule.

Will the 90% gambling loss cap be repealed?

Bills like the FAIR BET Act and the FULL HOUSE Act aim to restore the 100% deduction, but as of early 2026 they have stalled, since the House Rules Committee declined to advance FAIR BET. Plan as if the cap applies.

What records do I need to claim gambling losses?

Keep a contemporaneous log of dates, locations, and amounts won and lost, plus supporting documents like W-2Gs, tickets, and statements. The session method lets you net wins and losses within a single continuous session.
