You cannot get a refund on gambling winnings themselves, but you may owe less tax overall if you had losses

The IRS treats gambling winnings as income you must report. Once you report them, you cannot get that money back as a refund just because you won it. However, if you had gambling losses in the same year, you can subtract those losses from your winnings on your tax return — and that subtraction might lower the tax you owe, or increase a refund you were already getting from other income.

The key difference: you cannot deduct losses to get a refund on the winnings themselves. You can only use losses to reduce the taxable amount of your total winnings. If your losses were larger than your winnings, you still cannot claim the extra loss as a deduction — the IRS only lets you use losses to offset wins, not to create a loss you can carry forward or claim separately.

Key Takeaways

  • Gambling winnings are taxable income and must be reported to the IRS; you cannot get a refund on the winnings amount itself.
  • You can subtract gambling losses from gambling winnings on your tax return, which may lower your overall tax bill or increase a refund from other income sources.
  • The IRS only allows you to deduct losses up to the amount of your winnings in the same year — losses larger than winnings cannot be claimed.
  • You must itemize deductions on Schedule A to claim gambling losses; the standard deduction does not include them.
  • Casinos, sportsbooks, and lottery operators report large wins to the IRS, so unreported winnings can trigger an audit.

What counts as a gambling loss you can deduct

A gambling loss is money you spent on gambling activities and did not get back. This includes losses at casinos, sportsbooks, horse racing tracks, poker rooms, lottery tickets, slot machines, and online gambling sites. The loss is the amount you wagered minus any winnings from that same session or day.

You can only deduct losses if you itemize deductions on Schedule A of your tax return. Most people use the standard deduction instead, which means they cannot claim gambling losses at all. If your total itemized deductions (including gambling losses, mortgage interest, charitable donations, and state taxes) exceed the standard deduction for your filing status, then itemizing makes sense and you can include gambling losses in that total.

For 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your gambling losses plus other deductible expenses add up to more than that, you should itemize. If not, claiming the losses does not help you.

How to document losses the IRS will accept

The IRS requires proof of your losses. Casinos and sportsbooks issue receipts, statements, or year-end summaries showing your activity. Keep every receipt, ticket stub, and account statement from any gambling you did during the year. If you gambled online, read and save your account history showing deposits, wagers, and withdrawals.

For lottery tickets, keep the tickets themselves and any receipts. For casual gambling with friends, keep a written log with the date, location, people present, and amount lost — the IRS knows these are harder to document, but a contemporaneous log (written at the time, not months later) is better than nothing.

If the IRS audits you and you cannot produce records, they will not let you claim the losses. Casinos are required to report winnings over $1,200 on Form W-2G, and sportsbooks report large payouts the same way. If you report winnings but have no documentation of losses, the auditor will question why.

The difference between what casinos report and what you owe

When you win more than $1,200 at a casino or $600 at a sportsbook (the threshold varies by state and type of bet), the operator files Form W-2G with the IRS and sends you a copy. That form shows the gross winnings — the full amount you won, before any losses that day.

Your actual taxable gambling income is your total winnings minus your total losses for the entire year. So if a casino reports a $2,000 win on Form W-2G, but you lost $3,000 at that same casino on other visits, your net taxable gambling income from that casino is negative. You still report the $2,000 win, but you also claim the $3,000 in losses, and the IRS reduces your taxable income by the difference.

The casino does not know about your losses elsewhere, so the Form W-2G will always show only the win. It is your job to report the losses on Schedule A when you file your return. If you do not, the IRS computer will see the reported win and expect you to pay tax on it — which is why documentation matters.

When losses exceed winnings in the same year

If you lost $5,000 and won $2,000 in the same year, your net is a $3,000 loss. You can use the $2,000 in losses to offset the $2,000 in winnings, bringing your taxable gambling income to zero. The remaining $3,000 in losses cannot be claimed. You cannot deduct it, carry it forward to next year, or use it to reduce other income like wages or investment gains.

This is one of the strictest rules in tax law. Gambling losses are only useful to the extent they offset gambling winnings in the same tax year. If you break even or lose money overall, gambling losses do not help you on your tax return.

How a loss deduction changes your refund or tax bill

Suppose you won $10,000 gambling and had $6,000 in losses. Your taxable gambling income is $4,000. If that is your only income, you owe tax on $4,000 instead of $10,000. At a 22 percent federal tax rate, that saves you $1,320 in tax.

If you also earned $50,000 in wages and had $2,000 withheld from your paycheck, your total taxable income is $54,000 (wages plus net gambling income). The $2,000 withheld might be less than the tax you owe on $54,000, so you would owe more at filing. Or it might be more, in which case you get a refund. The gambling loss deduction reduces your total taxable income, which could lower what you owe or increase your refund — but it does not create a refund on the gambling winnings themselves.

State taxes on gambling winnings

Most states that have income tax also tax gambling winnings. Some states tax only casino and sportsbook winnings, while others include lottery winnings. A few states, like Nevada and Wyoming, have no income tax at all, so there is no state tax on gambling winnings there.

State tax rules on loss deductions vary. Some states follow federal rules and let you deduct losses only to the extent of winnings. Others are stricter and do not allow loss deductions at all, even if you itemize on your federal return. Check your state's tax authority website or speak with a tax preparer who knows your state's rules, because a loss deduction that works federally might not work at the state level.

Frequently Asked Questions

If I won $5,000 at a casino and lost $8,000 total that year, can I claim the $3,000 extra loss?

No. You can use $5,000 of your losses to offset the $5,000 win, bringing your taxable gambling income to zero. The remaining $3,000 in losses cannot be claimed on your return, carried forward to next year, or used to reduce other income. Gambling losses only offset gambling winnings in the same year.

Do I have to report gambling winnings if they were not reported to the IRS on a W-2G?

Yes. You must report all gambling winnings, whether or not the casino or sportsbook filed a Form W-2G. The IRS expects you to report income from all sources. If you do not report winnings and the IRS finds out through an audit or other means, you will owe back taxes, interest, and penalties.

Can I deduct gambling losses if I take the standard deduction?

No. Gambling losses are only deductible if you itemize deductions on Schedule A. If you claim the standard deduction, you cannot claim gambling losses, even if you have documentation. You have to choose: either itemize and include gambling losses along with other deductible expenses, or take the standard deduction and claim no gambling losses.

What if I gambled in multiple states — do I report losses separately by state?

On your federal return, you combine all gambling winnings and losses from all locations into one net amount. You do not report them by state. However, some states require you to report winnings and losses separately for that state's tax purposes, so check your state's rules. You may need to file a separate state return or schedule for gambling income.

If a sportsbook or casino did not send me a W-2G, do I still have to report the win?

Yes. You must report all winnings regardless of whether you received a Form W-2G. The threshold for filing W-2G varies — some sportsbooks report wins over $600, others over $1,200 — but the IRS requires you to report all gambling income. Keep your own records so you can prove the amount if audited.
