State taxes on gambling winnings apply in 41 states and the District of Columbia, where your winnings get added to your other taxable income and taxed at your state’s ordinary income rates. Nine states impose no personal income tax at all, so residents there owe nothing at the state level on a casino jackpot, sports bet, or lottery prize. Everywhere else, the questions worth answering are what rate applies, what happens when you win outside your home state, and whether you can offset winnings with losses.
Which States Don’t Tax Gambling Winnings
Residents of Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming pay no state personal income tax on any income, gambling included.1Tax Foundation. State Individual Income Tax Rates and Brackets, 2025 Winnings at a casino, sportsbook, or lottery counter in those states are subject to federal tax only. New Hampshire fully repealed its tax on interest and dividends starting in 2025, which is what makes the no-income-tax list a clean nine states.
A few states with income taxes carve out narrower exemptions, most often for their own state lottery. Winnings from that state’s lottery may be exempt while casino payouts and sports betting income are taxed at full rates. A multi-state game like Powerball or Mega Millions isn’t always treated the same way as the in-state lottery, so it’s worth checking your state’s specific rule before assuming a prize is exempt.
How the Rest of the States Tax Your Winnings
The other 41 states and D.C. fold gambling winnings into your total taxable income. There is no separate gambling tax rate; your winnings are added to wages and other income, and you pay your state’s normal rates on the combined total.
Those rates vary widely. Top marginal rates range from 2.5% in a handful of states to over 13% in the highest-tax state.1Tax Foundation. State Individual Income Tax Rates and Brackets, 2025 About a dozen states use flat rates. The rest use graduated brackets, and a single large payout can push you into a higher bracket for the year even when your regular salary wouldn’t reach it.
Some states withhold a percentage of large payouts at the source, typically somewhere between 3% and 7% depending on the state and whether you’re a resident. Withholding is an advance payment against your actual liability, not the final bill. You reconcile the difference when you file your state return — if too much was withheld, you get a refund; if too little, you owe.
When You Win in Another State
If you win at a casino, racetrack, or sportsbook in a state where you don’t live, that state generally gets the first right to tax the income. You’ll likely need to file a non-resident return there, even for a modest amount. The source state treats you the same as anyone else earning income within its borders.
To keep you from being taxed twice, most home states offer a credit for income tax already paid to another state. You calculate what your home state would charge on the winnings and subtract what the other state collected. If the source state’s rate was lower, you owe your home state the difference. If the source state has no income tax, your home state collects the full amount.
The credit isn’t automatic. You have to file the specific credit form your state uses and document what you paid elsewhere. Skip that step and you’ll effectively pay twice. Instructions for your state return will list the credit for taxes paid to other jurisdictions; almost every state with an income tax has one.
Online Betting Across State Lines
Mobile sports betting adds a wrinkle. When you place a bet on your phone while physically in another state, the state where you’re standing when the bet is placed generally has taxing authority, not the state where the sportsbook is licensed or where you live. A weekend trip can create a non-resident filing obligation.
Online sportsbooks are generally required to report your winnings to the state where the bet was placed and withhold state tax when applicable. If you only bet from home, this doesn’t affect you. If you travel and bet in multiple states, you could face returns in each of them, and keeping track of which winnings belong to which state is your job. The same credit mechanism for taxes paid to other states still applies.
Deducting Losses on Your State Return
Federally, you can deduct gambling losses up to the amount of your winnings, but only if you itemize on Schedule A.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses Many states follow the same approach. About a dozen states do not — including Connecticut, Illinois, Indiana, Kansas, North Carolina, and Ohio — meaning no gambling loss deduction is available at the state level regardless of your losses.
In those states, if you won $15,000 and lost $20,000 over the year, you still owe state tax on the full $15,000. That’s a real tax bill on money you never actually kept. The federal return can zero out a break-even or losing year; the state return in these jurisdictions cannot. This is where casual gamblers most often get an unpleasant surprise.
Even in states that do allow the deduction, the rules come with limits. You generally have to itemize instead of taking the standard deduction. Deductible losses can never exceed reported winnings, and gambling losses can’t offset your salary, investment income, or any other earnings.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses
What the Casino Reports to Your State
Gaming establishments issue a Form W-2G when winnings hit certain thresholds. For 2026, the reporting threshold for slot machines, bingo, and keno is $2,000, up from the previous $1,200 for slots and bingo and $1,500 for keno.3Internal Revenue Service. Instructions for Forms W-2G and 5754 For other types of gambling, including table games, sports bets, and poker tournaments, a W-2G is required when the payout exceeds $5,000 and is at least 300 times the wager.4GovInfo. 26 USC 3402 – Income Tax Collected at Source
A copy of the W-2G goes to your state tax authority.3Internal Revenue Service. Instructions for Forms W-2G and 5754 Box 1 shows gross winnings, Box 13 identifies the state, and Box 15 shows any state tax already withheld. State revenue departments routinely cross-reference these forms against filed returns to catch omissions.
One point trips people up: winnings below the W-2G threshold are still taxable. An $800 slot win in 2026 generates no W-2G, but you owe state income tax on it anyway. The W-2G is a reporting trigger for the casino, not the point at which the income becomes taxable. All gambling income is taxable whether or not a form is issued.2Internal Revenue Service. Topic No. 419, Gambling Income and Losses
If you fail to report gambling income, states generally impose a late-filing or underreporting penalty as a percentage of the unpaid tax per month, plus interest until the balance is paid. Penalty structures vary; some states charge as little as 1% per month, others match or exceed the federal 5%-per-month failure-to-file rate, which caps at 25%.5Internal Revenue Service. Topic No. 653, IRS Notices and Bills, Penalties and Interest Charges Deliberate fraud carries substantially higher fines and possible criminal exposure.
Records to Keep in Case Your State Asks
State tax authorities apply the same recordkeeping standard the IRS uses during audits. You’re expected to maintain a contemporaneous gambling diary showing the date and type of each wager, the name and location of the establishment, anyone with you, and the amounts you won or lost.6Internal Revenue Service. Diary or Similar Record
Without a diary, you have no way to substantiate loss deductions, and an auditor can disallow them entirely. Keep W-2Gs, losing tickets, player’s club statements, and any other documentation alongside the log. For online play, your sportsbook or casino app usually offers a downloadable transaction history — save it at year’s end before it disappears from the platform.
The format doesn’t matter. A spreadsheet, a phone note, or a pocket notebook all work. What matters is that the record was kept at or near the time of the activity and includes the required details. A log reconstructed during an audit carries far less weight than one maintained in real time.
