Online Casino Taxes: Reporting Winnings and Losses
Gambling winnings are taxable income under federal law, and most states with income taxes follow suit. Whether you hit a jackpot on an online slot or grind out steady profits at blackjack, the IRS expects you to report those winnings. Understanding your tax obligations helps you avoid surprises and take advantage of legitimate deductions.
Federal Tax on Gambling Winnings
All gambling winnings are subject to federal income tax at your ordinary income rate. This includes online casino winnings, slot jackpots, table game profits, tournament prizes, and sweepstakes redemptions. You must report all winnings on your annual tax return regardless of whether you receive a tax form. The IRS considers net session winnings taxable—if you deposit $200, play for an hour, and cash out $500, the $300 profit is reportable income.
When You Receive a W-2G
Casinos are required to issue a W-2G form for certain winning thresholds. For slots and bingo, a W-2G is generated for wins of $1,200 or more. For poker tournaments, the threshold is $5,000. For other games, the threshold is generally $600 or more at odds of 300:1 or greater. Some casinos withhold 24% federal tax from W-2G wins. Even if your winnings fall below W-2G thresholds, you are still legally required to report them. Keep detailed records of your gambling activity. See our [state guide](/states) for state-specific tax information.
Deducting Gambling Losses
The good news is that gambling losses are deductible—up to the amount of your gambling winnings. If you won $5,000 and lost $3,000 during the year, you can deduct the $3,000 in losses, reducing your taxable gambling income to $2,000. However, you must itemize deductions on Schedule A to claim gambling losses. You cannot deduct losses against other income—only against gambling winnings. You also cannot carry losses forward to future years. Maintain a gambling diary that records dates, venues, game types, amounts wagered, and results for every session.
State Taxes on Gambling
Most states with an income tax also tax gambling winnings. Tax rates and rules vary significantly. Some states tax all gambling income at the standard rate, while others offer specific deductions. A few states with no income tax—such as Nevada, Florida, and Texas—do not tax gambling winnings at the state level. Note that you owe state tax to the state where the gambling activity occurred, not necessarily where you live.

Record-Keeping Best Practices
The IRS recommends maintaining a detailed gambling diary that includes the date and type of each wager, the name and address of the casino, the names of other people present (for table games), and the amounts won and lost. Online casino account statements and transaction histories are valuable supporting documents. Save these records for at least three years after filing, which is the standard IRS audit window.

Frequently Asked Questions
Do I have to report small online casino winnings?
Yes. All gambling winnings are legally reportable regardless of the amount. Even if you do not receive a W-2G, you are required to include gambling income on your tax return.
Can I deduct more in losses than I won?
No. Gambling loss deductions are capped at the amount of gambling winnings you report. If you won $2,000 and lost $5,000, you can only deduct $2,000 in losses. You cannot use the excess $3,000 to offset other income.
Should I hire a tax professional for gambling income?
If your gambling activity is significant or you play across multiple states, a tax professional familiar with gambling income can help you maximize deductions and ensure compliance. For small, occasional winnings, standard tax software can handle the reporting.
