Do You Have to Pay Taxes on Online Gambling?

Yes, you owe taxes on online gambling winnings. Every dollar you win through a sportsbook app, online casino, poker site, or daily fantasy platform is taxable federal income, reported on your Form 1040 and taxed at your ordinary rate. For 2026, two changes matter: platforms only issue a Form W-2G once your winnings hit $2,000, and if you deduct losses, the One Big Beautiful Bill Act caps that deduction at 90% of your winnings.

What Counts as a Winning You Have to Report

The Internal Revenue Code defines gross income as all income from whatever source derived.¹ The IRS applies that definition plainly to gambling: winnings from lotteries, raffles, sports betting, horse races, and casinos all belong on your return.²

Two points trip people up. First, you report winnings even when no tax form arrives. Platforms only issue a W-2G at specific thresholds, but the reporting duty exists for every winning bet regardless. The small, frequent wins add up. Second, non-cash prizes count. Win a car or a vacation package in a promotion and you owe tax on its fair market value.² Check the value the platform assigns against the actual retail price before you accept it.

The 90% Loss Deduction Cap for 2026

You can deduct gambling losses, but only against gambling winnings, and only if you itemize. Losses from wagering are allowed only to the extent of gains from those same transactions.³ Starting in 2026, the One Big Beautiful Bill Act caps that deduction at 90% of your winnings, down from 100%.

Here is what that looks like. Say you win $10,000 across sports bets and online poker in 2026 and lose $12,000 over the same year. You report $10,000 as income and can deduct $9,000 in losses. You owe tax on $1,000 even though you finished the year down $2,000. Under the pre-2026 rule, that scenario produced zero taxable gambling income.

The itemizing requirement adds another filter. Loss deductions belong on Schedule A, not netted against your winnings on Schedule 1.² For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.⁴ If your total itemized deductions, including gambling losses, don’t clear that number, itemizing costs you money. Most casual online bettors are better off taking the standard deduction and paying tax on their full winnings.

One more mechanical point on losses: you can’t net wins and losses across days or across games. The IRS treats each session at a single location on a single day as one unit for slot play.⁵ Win $500 Monday and lose $400 Tuesday and you report $500 in winnings plus $400 in losses, not a $100 net.

Form W-2G and the New $2,000 Threshold

For 2026, the minimum triggering a Form W-2G has been adjusted for inflation to $2,000.⁶ That’s a meaningful shift from prior years, when a $1,200 slot jackpot or a $600 sports bet at 300 times the wager generated the form. Fewer automatic forms will land in your inbox, but nothing about your reporting duty changes.

The specific rules by game type all reference the same $2,000 floor:

Slot machines, bingo, and keno: a W-2G is issued when winnings meet or exceed $2,000.
Sports betting and horse racing: a W-2G is required when winnings meet or exceed $2,000 and are at least 300 times the amount wagered.
Poker tournaments: a W-2G is issued when net winnings meet or exceed $2,000.
Sweepstakes and lotteries: a W-2G is required when winnings meet or exceed $2,000.

The platform files the W-2G with the IRS and sends you a copy.⁷ If you bet on several apps, expect several forms, and check each one for accuracy before filing. When the IRS sees a mismatch between the W-2Gs on file and what you reported, it sends a notice.

Withholding and Quarterly Estimated Payments

Big wins often come with tax already taken out. Federal law requires the payer to withhold 24% when net winnings exceed $5,000 from sweepstakes, lotteries, sports wagering, and parimutuel pools; for sports bets and racing, the winnings must also be at least 300 times the wager.⁶ The 24% is computed on the full winnings minus the wager, not just the amount above $5,000.⁸

Bingo, keno, and slot winnings are exempt from this regular withholding even above $5,000.⁸ Backup withholding of 24% kicks in on any reportable winnings if you didn’t give the platform a valid taxpayer identification number.⁶ The amount withheld is a prepayment against your total tax bill. If your rate is higher, you owe the difference. If it’s lower, you get a refund.

Withholding doesn’t always cover the tax you’ll owe, and many wins never trigger withholding at all. You may need quarterly estimated payments to avoid an underpayment penalty. The IRS expects estimated payments when you expect to owe at least $1,000 after subtracting withholding and refundable credits, and your withholding covers less than 90% of the current year’s tax or 100% of the prior year’s, whichever is smaller.⁹ A big January sportsbook win creates a liability the IRS doesn’t want to wait 15 months to collect. If your gambling income is lumpy, you can use the annualized installment method.¹⁰ Miss the quarterly deadlines and the penalty accrues interest.

Records You Need to Keep

The IRS expects a contemporaneous log of gambling activity, and this is what separates a smooth filing from an audit headache. A usable log includes:

The date and the specific type of wager or game.
The name and address of the gambling establishment or platform.
How much you won or lost on each session.
The names of anyone gambling with you at the time.

These requirements come from IRS guidance on gambling recordkeeping.¹¹ For online play, screenshots of your account transaction history, deposit and withdrawal records, and platform-generated win/loss statements do the work that paper tickets used to do.

Keep the records at least three years after you file the return they support. The standard IRS audit window is three years from the filing date, but it stretches to six years if you understate income by more than 25%. Longer retention is the safer call. Don’t destroy the tax returns themselves.

Where the Numbers Go on Your Return

Winnings go on the “Other Income” line of Schedule 1, which flows into your Form 1040. Report the full amount. Don’t subtract losses first. If you’re itemizing to claim losses, those go on Schedule A under “Other Itemized Deductions.”² The IRS wants both numbers shown separately.

E-filed returns typically produce a refund in about three weeks; paper returns take six weeks or more.¹²

State Taxes and Offshore Accounts

Federal tax isn’t the whole picture. Most states also tax gambling winnings as income at whatever bracket applies to you. Roughly ten states have no income tax or specifically exempt gambling winnings; if you live anywhere else, expect a state bill too. Some states require withholding on payouts, others don’t. Check your state tax authority for the specific rate and filing rules.

If you play on an offshore site and hold funds in a foreign account, a separate reporting rule may apply. Any U.S. person with a financial interest in foreign accounts whose combined value exceeds $10,000 at any point during the year has to file a Report of Foreign Bank and Financial Accounts (FBAR) using FinCEN Form 114. It’s filed electronically through FinCEN’s BSA E-Filing System, not with your tax return, and it’s due April 15 with an automatic extension to October 15.¹³ Whether the account produced taxable income is irrelevant. Penalties for missing the FBAR are steep, and account records tied to reported FBARs must be kept five years from the due date. Most players on domestic licensed apps won’t hit this, but check if you use an overseas site.

What Underreporting Costs

The IRS receives every W-2G every platform files, which makes unreported winnings easy to spot. The least painful outcome of a mismatch is a notice and a corrected bill. Beyond that, the accuracy-related penalty adds 20% to any underpayment caused by negligence or a substantial understatement of income.¹⁴ If the IRS finds the underreporting was intentional, the fraud penalty jumps to 75% of the underpayment attributable to fraud.¹⁵ Criminal prosecution of individual bettors is rare but possible for large, deliberate omissions. Reporting everything and keeping clean records is the whole defense you need.
