Do I Pay Taxes on Sports Betting Winnings?

Yes, you owe federal tax on every dollar you win from sports betting, whether the sportsbook sends you a tax form or not. The IRS treats winnings as “other income,” and starting with the 2026 tax year, a new law caps your deductible losses at 90% of your winnings. That single change means some bettors who broke even at the window will still owe tax on paper. Here is what to know about taxes on sports betting winnings before you file.

All Winnings Count, Not Just the Big Ones

Federal law defines gross income as “all income from whatever source derived,” and gambling winnings sit squarely inside that definition.¹ A $20 parlay, a $5,000 futures hit, and a seven-figure Super Bowl payout are treated the same way: reportable income in the year you receive it. The obligation to report doesn’t depend on getting a form from the sportsbook. If you won it, you owe tax on it, and the IRS expects you to track it.²

This applies no matter how you placed the bet. Mobile apps, retail sportsbooks, fantasy contests, and casual wagers with friends all generate taxable income when you win. Non-cash prizes such as trips or merchandise count too, at their fair market value.

The 90% Loss Deduction Cap Starts in 2026

Before 2026, you could deduct gambling losses dollar-for-dollar against your winnings, up to the total you won. The One Big Beautiful Bill Act changed that. Starting with the 2026 tax year, you can only deduct 90% of your gambling losses against your winnings.³ The other 10% becomes taxable income you cannot offset.

Here is what that looks like. If you win $10,000 and lose $10,000 in the same year, you would previously have owed nothing on gambling income. Under the new rule, only $9,000 of those losses is deductible, leaving $1,000 in taxable gambling income. For someone in the 22% bracket, that is $220 in federal tax on a year you broke even at the sportsbook.

The catch is that your sportsbook’s win/loss statement will show zero net profit while the IRS sees taxable income. That mismatch is where a lot of bettors get surprised.

When the Sportsbook Sends You a W-2G

Sportsbooks file Form W-2G with the IRS when your winnings from a single wager meet two conditions: the payout is at least $2,000, and it is at least 300 times your bet.⁴ The $2,000 figure is new for 2026, up from the long-standing $600 threshold. You and the IRS both get a copy.

The 300-to-1 ratio matters. A $10 bet that pays $3,000 triggers a W-2G because the payout exceeds $2,000 and the ratio is 300:1. A $100 bet that pays $3,000 does not, because 30:1 misses the ratio. The winnings are still taxable in either case. You just won’t get the paperwork.

When a W-2G is required, the sportsbook will ask for your Social Security number and address before releasing the funds. If you don’t provide a correct taxpayer identification number, the operator must apply backup withholding at 24%.⁵

Withholding Kicks In at a Higher Number

Reporting and withholding are separate rules with separate thresholds. The sportsbook must withhold 24% of your net winnings (payout minus wager) when those net winnings exceed $5,000 and the payout is at least 300 times the bet.⁶ The 24% comes out of the proceeds, not the original stake.

That withholding is an estimate, not a final tax bill. If you are in a higher bracket, you will owe more when you file. If you are in a lower bracket, you may see some of it back as a refund.

How to Report It on Your Return

Report the full amount of your winnings on Schedule 1 (Form 1040) as other income. That figure flows into your adjusted gross income (AGI) on the main return.² Report the gross amount won, not the net after losses. If you received a W-2G with withholding, still include the full winnings as income and claim credit for the withholding separately.

To deduct losses, you have to itemize on Schedule A instead of taking the standard deduction. Losses go under “Other Itemized Deductions.” You can only deduct up to the amount of winnings you reported, and for 2026, only 90% of those losses count.³ You cannot use gambling losses to reduce income from your job, investments, or any other source.²

The Standard Deduction Trap

For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.⁷ Because gambling losses require itemizing, you only benefit from the deduction if your total itemized deductions (gambling losses plus mortgage interest, state taxes, charitable gifts, and other qualifying items) exceed the standard deduction.

For most casual bettors, the math doesn’t work. Say you’re single, you won $4,000 and lost $4,000, and you have $8,000 in other itemizable expenses. Your total itemized deductions come to $11,600, which is $8,000 plus 90% of $4,000 in losses. That’s less than the $16,100 standard deduction, so you would take the standard deduction and get no benefit from those losses. Meanwhile, the $4,000 in winnings still sits in your AGI. This is where casual bettors get stung.

A Full 2026 Example

A bettor wins $8,000 and loses $8,000 during 2026. They report $8,000 in winnings on Schedule 1. On Schedule A, the deductible loss is $7,200, or 90% of $8,000. Even assuming they itemize, they have $800 in taxable gambling income. At the 22% bracket, that’s $176 in federal tax on a year they broke even.

Do You Need to Make Estimated Payments?

If the sportsbook didn’t withhold, or the 24% withheld doesn’t cover your actual rate, you may need to make quarterly estimated tax payments to avoid an underpayment penalty. Bettors used to employer withholding often miss this.

The IRS charges an underpayment penalty unless you meet one of these safe harbors: you owe less than $1,000 when you file, you have paid at least 90% of your current-year tax through withholding and estimated payments, or you have paid at least 100% of your prior-year tax (110% if your AGI was above $150,000).⁸

For the 2026 tax year, quarterly estimated payments are due April 15, June 15, and September 15 of 2026, and January 15, 2027.⁹ If a big win lands in August, make the estimated payment by the September deadline rather than waiting until the spring.

Winnings Inflate Your AGI, and That Ripples

Winnings hit your AGI at the full gross amount. Losses only reduce your taxable income through itemized deductions. The gap between those two numbers matters, because AGI is what the government uses for a long list of benefits and thresholds.

Higher AGI from gambling can raise your Medicare Part B and Part D premiums through the Income-Related Monthly Adjustment Amount. Medicare uses AGI from two years prior, so a big 2026 year could raise your 2028 premiums. Gambling winnings also flow into the AGI used on the FAFSA for college financial aid, and FAFSA doesn’t account for itemized deductions, so your losses won’t offset the inflated income figure. Parents with college-age kids should pay attention here.

Other AGI-sensitive thresholds include marketplace health insurance premium tax credits, Roth IRA contribution eligibility, and the phaseout of various tax credits. A $15,000 win offset by $15,000 in losses still raises your AGI by $15,000, even if your taxable income barely moves.

Free Bets and Promotional Credits

Sign-up bonuses, free bets, and deposit matches confuse almost everyone. The general principle: a promotional credit you cannot withdraw as cash isn’t income when you receive it. It’s closer to a discount on a future bet. But if you place a free bet and it hits, those winnings are taxable like any other payout.

If a sportsbook gives you a $500 free bet and it loses, there is nothing to report. If it wins $1,200, you report $1,200 as gambling income. You don’t get to deduct the $500 as a loss because you never risked your own money. Some sportsbooks include free bet winnings on a W-2G when the thresholds are met; others don’t. Either way, the income is taxable and reporting it is on you.

State Taxes Are a Separate Question

Most states with an income tax also tax gambling winnings, usually at their regular rates. A handful don’t allow any deduction for gambling losses, which means you could owe state tax on your gross winnings even in a losing year. The new federal 90% cap compounds that in states that follow federal rules. Some states require the sportsbook to withhold at payout; others leave it to you at filing. State revenue departments increasingly share data with the IRS, so unreported gambling income tends to surface.

If You Bet Full-Time as a Business

A brief boundary for the small number who need it: if you pursue gambling “full time, in good faith, and with regularity, to the production of income for a livelihood,” the IRS may classify you as a professional gambler, per the Supreme Court’s standard in Commissioner v. Groetzinger. Professionals report income and expenses on Schedule C and pay self-employment tax, and the 90% loss cap applies to them too, covering both wagering losses and related business expenses.³ Most bettors don’t come close to meeting the standard, and claiming it without a real basis invites an audit.²

Records to Keep Now

The IRS expects records that substantiate both your winnings and your losses.² Most sportsbooks generate an annual win/loss statement you can download from your account. That’s a starting point, not the whole story. Keep the following:

Win/loss statements from every sportsbook you used during the year, downloaded before they archive them.
Every Form W-2G you receive. If you should have received one and didn’t, contact the sportsbook.
A bet-by-bet log with dates, types of bets, amounts wagered, and amounts won or lost. A spreadsheet is fine. The IRS values records kept during the year over summaries built at tax time.
Deposit confirmations, withdrawal records, and payout receipts from retail locations.

Thorough records are your primary defense in an audit. The IRS uses automated matching to flag returns where reported gambling income doesn’t line up with the W-2Gs sportsbooks filed, and resolving a mismatch without documentation is an uphill fight.
