Are Gambling Losses Deductible? The 90% Cap and Three Limits

Are gambling losses deductible? Yes, but three limits apply, and together they can leave you owing tax even after a losing year. You can only deduct losses if you itemize deductions on Schedule A, you can only deduct up to the amount of gambling winnings you report, and for tax years beginning in 2026 you can only deduct 90 percent of your losses under the amended Internal Revenue Code Section 165(d).¹ These rules cover every form of gambling: casino play, sports betting, lotteries, horse racing, and everything in between.

The Three Limits on Gambling Loss Deductions

Start with itemizing. Recreational gamblers claim losses only as an itemized deduction on Schedule A of Form 1040. Take the standard deduction and your losses do nothing for you, while your winnings remain fully taxable.²

Next, the winnings cap. Even when you itemize, your deduction cannot exceed the gambling income you reported for the year. Losses can never create a net loss for tax purposes, and they cannot offset wages, interest, investment gains, or any other income.¹ Excess losses do not carry forward to a future year. They simply disappear.

Third, the new 90 percent cap. For tax years beginning in 2026, the One Big Beautiful Bill Act changed the longstanding dollar-for-dollar rule. You can now deduct only 90 percent of your gambling losses, and still only up to the amount of your winnings. The cap applies to both recreational and professional gamblers.

Why a Break-Even Year Can Still Trigger Tax

The 90 percent limit means the deduction can no longer fully wipe out your winnings, even when your losses match or exceed them. Won $10,000 and lost $10,000 in the same year? You can deduct $9,000, leaving $1,000 of taxable gambling income despite ending the year exactly where you started.

The gap grows with volume. A gambler who won $201,000 and lost $200,000 walks away with $1,000 in net winnings but can only deduct $180,000 of losses, producing $21,000 of taxable income. High-volume recreational players who churn through large amounts of action feel this most sharply, because the 10 percent slice of disallowed losses scales with total losses, not with net profit.

Do the Standard Deduction Math First

Itemizing only pays off when your total itemized deductions beat the standard deduction. For 2026, the IRS inflation-adjusted standard deduction amounts are $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.³

Add up your gambling losses, mortgage interest, charitable contributions, and state and local taxes (capped separately). If the total clears your standard deduction, itemizing wins. If it doesn’t, the standard deduction saves you more, and your gambling losses go unclaimed even though you were entitled to them in theory.

Winnings Raise Your AGI Even When You Deduct Losses

Gambling winnings land on Schedule 1 and feed into your gross income at the top of the return. Loss deductions live down on Schedule A. That order matters: your adjusted gross income reflects the winnings in full, regardless of losses claimed later.

A higher AGI can ripple through parts of your finances that have nothing to do with gambling. Premium tax credits for marketplace health insurance can shrink or vanish if winnings push your income past the subsidy threshold. Medicaid uses modified adjusted gross income, so a single large win can knock out coverage even when you ultimately broke even or lost money for the year.⁴ Federal student aid uses tax return data through the FAFSA, so a spike in AGI can cut aid eligibility for a dependent’s college year.

Taxpayers who assume that offsetting losses put them “back to square one” often discover the AGI problem months later, when a benefit or credit gets clawed back.

Records You Need to Claim the Deduction

The IRS expects a diary or similar log tracking every gambling session throughout the year. The log should record the date and type of activity, the name and location of the venue, and the amounts won or lost during each session.⁵

Back the log up with supporting documents:

Forms W-2G issued by venues for reportable winnings
Wagering tickets, including unredeemed and losing bet slips
Canceled checks, credit card statements, and bank withdrawal records
Any statements of winnings or payment slips provided by the gambling establishment

Records need to show specific amounts for each session rather than a single yearly estimate. Lump-sum claims without session-level backup are one of the most common reasons the IRS disallows gambling loss deductions on audit.²

One note on what “session” means: an IRS-proposed safe harbor for electronically tracked slot machine play defines a session as all play on the same type of game, at the same establishment, during a single calendar day, with wins and losses netted within the session but not across sessions.⁶ The method has not been finalized but signals how the IRS views session-level reporting.

Hold onto everything for at least three years from the date you file the return that claims the deduction, matching the standard audit statute of limitations.⁷

How to Report Winnings and Losses on Your Return

Report all gambling winnings on Schedule 1 (Form 1040), which flows into your total income. If you itemize, put your deductible losses on the “Other Itemized Deductions” line of Schedule A, remembering to apply the 90 percent cap for 2026.² Winnings must be reported in full even when the venue did not issue a Form W-2G. The absence of a W-2G does not make the income tax-free.

You do not attach receipts, logs, or W-2G forms to the return. Keep them on hand in case the IRS asks for verification.

If You Gamble Professionally

A gambler who plays with regularity and a genuine profit motive can be treated as running a trade or business, reporting income and expenses on Schedule C instead of itemizing. Courts weigh time devoted, expertise applied, and reliance on gambling for a livelihood when deciding whether that status fits.

Professionals can deduct ordinary business expenses tied to their gambling, such as travel, lodging, tournament entry fees, and handicapping subscriptions. For 2026, the TCJA-era rule that lumped these nonwagering expenses together with wagering losses under a single cap has expired, so ordinary business expenses come off separately.¹ The 90 percent limitation still applies to wagering losses themselves. Net profit is subject to self-employment tax at 15.3 percent, an extra layer recreational gamblers do not face. If the activity is a hobby rather than a business, the recreational rules apply and Schedule C is off the table.

Non-Resident Aliens and State Taxes

Non-resident aliens who are not residents of Canada generally cannot deduct gambling losses against U.S.-source winnings. Winnings are reported on Form 1040-NR using Schedule NEC and are typically subject to a flat 30 percent withholding, though tax treaties may reduce or eliminate it.²

State treatment varies. Most states with an income tax also tax gambling winnings, but not all allow a loss deduction. Some mirror the federal rules, others disallow the deduction outright, and others impose their own caps. Rates range from zero in states with no income tax to above 10 percent in the highest jurisdictions. Some states also tax winnings earned within their borders even if you are not a resident, so check the tax agency in both your home state and any state where you gambled.
