Tax Questions Every Online Casino Player Needs Answered

All gambling winnings are fully taxable ordinary income under US federal law — every dollar, whether from a $1 deposit session or a high-stakes table, must be reported to the IRS. No de minimis threshold exists for self-reporting. That surprises a lot of players who assume small wins don't count.

Do I have to report small casino winnings?

Yes. The IRS requires players to report all gambling winnings regardless of amount. Winning $40 on a slot at a licensed New Jersey casino is taxable income, same as winning $40,000. The casino may not issue any paperwork for small wins, but that does not change the player's reporting obligation.

For a deeper look at the rules, see How US Tax Law Applies to Online Casino Winnings in 2026. It covers withholding thresholds, Form W-2G, and what to do when winnings cross reporting triggers.

When does the casino withhold taxes automatically?

Casinos issue a Form W-2G and apply 24% federal withholding when certain thresholds are hit — for example, net winnings over $5,000 from wagering pools or lotteries, or payouts at odds greater than 300:1. Below those thresholds, no automatic withholding occurs, but the winnings are still taxable.

Federal tax rates on gambling income can reach 37% for the largest jackpots. State income taxes in regulated states — Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, West Virginia, and Rhode Island — layer on top at varying rates.

Can I deduct my casino losses?

Only if you itemize deductions on your federal return, and only up to the amount of your winnings. If a player wins $10,000 and loses $5,000 during the same tax year, the maximum deductible loss is $5,000. Losses cannot exceed winnings, and no deduction is available to players who take the standard deduction.

What is the 1099-K threshold for 2025 and 2026?

The 1099-K reporting threshold dropped to $5,000 for 2024 and is set to fall further to $600 beginning in 2025. A proposed $2,000 W-2G threshold for casino winnings is also noted for 2026. These shifts mean more players will receive tax documents than in prior years — another reason to keep accurate records of every session.

Does it matter if I'm playing at a sweepstakes casino vs. a real-money site?

It matters for legality, less so for taxes. Prize redemptions from sweepstakes platforms are still taxable income. For a full breakdown of how these platforms differ, see Is Online Casino Legal in My State? Common Questions Answered, and compare the two models at Sweepstakes Casino vs Real-Money Casino: The Actual Difference.

What records should I keep?

• Date and type of each gambling session
• Name and location (or URL) of the casino
• Amounts won and lost per session
• Any W-2G forms received from operators
• Deposit and withdrawal transaction history, available from the casino's account portal

Operators at regulated US online casinos — the seven legal states listed above — are required to maintain transaction histories. Download them. They are the fastest way to reconstruct session records if the IRS ever asks.
