Every dollar you win from sports betting is taxable income under federal law, whether it came from a mobile app, a retail sportsbook, or a daily fantasy contest.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses Sports betting taxes work on your gross winnings, not your net profit for the year, and starting with the 2026 tax year two changes reshape what you owe: the Form W-2G reporting threshold rose from $600 to $2,000, and a new federal rule caps your deductible gambling losses at 90% of what you actually lost.2Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026)
How Winnings Are Taxed
Report your gambling winnings on Schedule 1 (Form 1040), Line 8b, under “Gambling.”3Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income This holds even if no sportsbook sends you a tax form. Winnings get added to your other income and taxed at your ordinary income tax rate. There is no special lower rate for betting profits.
Losses are handled separately on a different form, which trips up a lot of first-time filers who assume they can just report the net difference. Win $8,000 and lose $10,000, and you report $8,000 as income. Whether any of those losses reduces your bill depends on whether you itemize, which most bettors don’t.
Hiding gambling income is tax evasion, a felony carrying fines up to $100,000 and up to five years in prison.4Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax Short of criminal charges, the IRS can add a 20% accuracy-related penalty to any underpayment tied to negligence or a substantial understatement of income.5Internal Revenue Service.

The 2026 Ninety Percent Loss Deduction Cap
This is the biggest change for bettors in years. Before 2026, you could deduct gambling losses dollar-for-dollar against your winnings, up to the amount you won. Starting with the 2026 tax year, federal law limits your deductible losses to 90% of your actual losses.6Office of the Law Revision Counsel. 26 USC 165 – Losses That deduction still cannot exceed your total winnings for the year.
Here is what that means in practice. Say you won $10,000 and lost $10,000. Under the old rules, the full $10,000 in losses wiped out your $10,000 in winnings and left zero taxable gambling income. Under the new rule, you can deduct only $9,000 of those losses, leaving $1,000 in taxable gambling income. Real money owed on a break-even year.
For married couples filing jointly, the cap applies to combined wins and losses.7Internal Revenue Service. Internal Revenue Bulletin 2026-19
When Sportsbooks Issue Form W-2G
For the 2026 tax year, sportsbooks must issue a Form W-2G when your winnings reach $2,000 or more and are at least 300 times your wager.2Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026) The threshold was $600 through 2025 and now adjusts annually for inflation. A $10 bet that pays out $3,000 triggers a W-2G because winnings exceed $2,000 and the payout is 300 times the wager. A $100 bet that pays $2,500 does not, because $2,500 is only 25 times the wager.
The form reports the amount won, the date of the wager, and any tax withheld. Sportsbooks typically deliver these by early February, either by mail or through your account. Keep every W-2G, because the IRS gets a copy and will match it against your return.
No W-2G does not mean no tax. You must report all gambling winnings regardless of whether a form was issued.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses Plenty of bettors accumulate thousands across small individual bets that never hit the W-2G threshold. The IRS still expects that income on your return.
How Withholding Works on Payouts
Withholding is money the sportsbook takes out of your payout and sends directly to the IRS before you see it. Two types apply to sports betting.
Regular gambling withholding kicks in when your net winnings (payout minus wager) exceed $5,000 and the payout is at least 300 times the wager. The sportsbook withholds 24% of the net winnings.2Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026)
Backup withholding also runs at 24% but applies when you fail to provide a valid taxpayer identification number to the sportsbook, or when the IRS has notified the operator that your TIN is incorrect.8Internal Revenue Service. Topic No. 307, Backup Withholding It can hit payouts below the $5,000 regular withholding line.
Either way, 24% withheld is a prepayment toward your tax bill, not necessarily what you owe. If your total tax rate is higher, you’ll owe more at filing. Lower, and you get a refund. The withheld amount shows up on your W-2G and gets credited on your return.
Deducting Your Betting Losses
You can deduct gambling losses only if you itemize deductions on Schedule A. Take the standard deduction and your losses do nothing for your tax bill.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses This is where many casual bettors get caught. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Unless your combined itemized deductions (mortgage interest, state taxes, charitable giving, and gambling losses) exceed those thresholds, itemizing costs you more than it saves.
Even when itemizing makes sense, two limits apply to gambling losses in 2026:
- You can deduct only 90% of your actual losses.6Office of the Law Revision Counsel. 26 USC 165 – Losses
- Your deductible losses (after the 90% reduction) still cannot exceed the gambling income you reported.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Two examples show how these interact. Win $5,000 and lose $6,000: 90% of $6,000 is $5,400, but that exceeds your $5,000 in winnings, so the winnings ceiling controls and your deduction is $5,000. Win $20,000 and lose $15,000: your deduction is $13,500 (90% of $15,000), leaving $6,500 in taxable gambling income where the old rules would have left $5,000.
Record-Keeping
The IRS requires a diary or similar record of your gambling activity, supported by receipts, tickets, statements, and other documentation.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses Your log should include date, location or platform, type of bet, amount wagered, and amount won or lost per session. Bank and card statements showing transfers to sportsbook accounts help corroborate the log.
Most online sportsbooks generate annual win/loss statements you can download. Useful, but not a substitute for your own records. If you bet across multiple platforms, you need records from each. The IRS does not accept a single year-end total with no supporting detail.
Quarterly Estimated Tax Payments
If your winnings push your expected tax bill (after withholding and credits) to $1,000 or more, you may need to make quarterly estimated payments to avoid an underpayment penalty.10Internal Revenue Service. Estimated Taxes This catches bettors who cash in early and assume they can settle up next April.
The 2026 deadlines:
- First quarter: April 15, 2026
- Second quarter: June 15, 2026
- Third quarter: September 15, 2026
- Fourth quarter: January 15, 2027
You can skip the January 15 payment if you file your 2026 return and pay the full balance by February 1, 2027.11Internal Revenue Service. 2026 Form 1040-ES If a sportsbook already withheld 24% from a large payout, that counts toward your obligation and may keep you under the $1,000 threshold.
Group Bets and Shared Prizes
When friends pool money on a bet and win, one person usually collects, but the IRS does not assume that person earned all of it. The collector should file Form 5754, which identifies each member of the group and their share.12Internal Revenue Service. About Form 5754, Statement by Person(s) Receiving Gambling Winnings The sportsbook then issues separate W-2G forms to each winner.
Without Form 5754, the person who collected gets a single W-2G for the whole amount and is on the hook to report the full payout as their own income. Sorting this out later, without documentation, creates a mess that filing the form at the time of the win avoids.
State Tax Obligations
Your state may also tax gambling winnings as ordinary income. Eight states have no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming. Bettors there deal only with the federal return. Elsewhere, state income tax applies at whatever rate the state charges on ordinary income.
Win a bet while visiting another state and that state may require a nonresident return on the income sourced there. You could owe two states on the same winnings, though most states offer a credit for tax paid to the other jurisdiction to prevent full double taxation. Check your home state’s rules before assuming a road trip win only involves one return.
State tax agencies routinely receive copies of federal forms like the W-2G and cross-reference them against state returns, so the idea that smaller winnings slip past at the state level is largely wishful thinking.
Professional Versus Recreational Bettor Status
Most sports bettors are recreational gamblers in the eyes of the IRS. If gambling is your primary source of income and you pursue it full time, with regularity, and with the intent to earn a living, you may qualify as a professional. The distinction changes how you file and what you can deduct.
Professionals report winnings, losses, and business expenses on Schedule C instead of splitting income onto Schedule 1 and losses onto Schedule A. That opens up deductions recreational bettors cannot claim, including travel, lodging, and subscriptions to data services. The tradeoff: net earnings face self-employment tax at 15.3%, covering Social Security and Medicare.13Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
Starting in 2026, the 90% loss cap applies to professionals too, and it covers business expenses in addition to wagering losses. The statute defines “losses from wagering transactions” to include any deduction incurred in carrying on a wagering transaction.6Office of the Law Revision Counsel. 26 USC 165 – Losses Combined losses and expenses can offset only up to 90% of winnings. Professional status still has advantages, but the gap narrowed considerably.
Pulling It Together at Filing Time
Three forms carry the load:
- Schedule 1 (Form 1040), Line 8b: total gambling winnings for the year, W-2G or not.3Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income
- Schedule A (Form 1040): if itemizing, allowable gambling losses (90% of actual, not exceeding winnings) under “Other Itemized Deductions.”1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
- Form W-2G: any tax withheld gets reported as federal income tax already paid, reducing your balance due or increasing your refund.
A common mistake is entering only the winnings shown on W-2G forms and ignoring smaller wins. The IRS expects total winnings from all sources, including the $200 parlay that never generated paperwork. Another is claiming losses without itemizing. If your total itemized deductions do not exceed the standard deduction, take the standard deduction and accept that the losses won’t offset your winnings.
