Yes, you must report gambling winnings as income to the IRS

The IRS treats gambling winnings as taxable income, regardless of whether you gamble occasionally or regularly. This includes winnings from casinos, racetracks, lotteries, online poker, sports betting, and scratch-off tickets. You owe federal income tax on the full amount you win, not just your net profit after losses.

The tax rate depends on your total income for the year and your filing status. Winnings are added to your other income — wages, interest, self-employment earnings — and taxed at your marginal rate, which can range from 10% to 37% at the federal level. Many states also tax gambling winnings, with rates varying from 0% to over 8% depending on where you live.

Casinos and other gambling venues report large wins to the IRS on Form W-2G. If you win $600 or more at a casino, $1,200 or more at a horse or dog track, or $5,000 or more from a lottery or keno game, the venue is required to file this form with the IRS and send you a copy. Smaller wins still count as taxable income even if no form is filed.

Key Takeaways

  • All gambling winnings are taxable income to the IRS, and you must report them on your tax return even if you receive no Form W-2G.
  • Casinos file Form W-2G for wins of $600 or more; lotteries and tracks have different thresholds, but all large wins are reported.
  • You can deduct gambling losses, but only up to the amount of your winnings, and only if you itemize deductions on your tax return.
  • State tax rates on gambling winnings range from 0% to over 8%, and some states tax winnings differently depending on the type of gambling.
  • Failing to report gambling income can result in penalties, interest, and IRS audit, even if the amount seems small.

How the IRS tracks your winnings

Large wins are tracked automatically through Form W-2G, which casinos and gambling venues must file when you hit certain thresholds. The form shows the gross amount you won, the amount withheld for taxes, and the type of gambling. The IRS receives a copy, and so do you — usually by January 31 of the following year.

Smaller wins are not reported to the IRS by the venue, but that does not mean they are not taxable. You are still required to report them on your tax return. The IRS cross-references W-2G forms with tax returns, so if you report a large win on Form W-2G but do not include it on your return, the IRS will notice the discrepancy.

Online gambling and sports betting create a more complex record. Some platforms issue Form 1099-MISC or 1099-NEC if you win above a certain threshold, while others may not report at all. Regardless, you are responsible for tracking your own winnings and losses and reporting them accurately.

Deducting gambling losses

The IRS allows you to deduct gambling losses, but with strict limits. You can only deduct losses up to the amount of your winnings — you cannot use gambling losses to offset other income like wages or investment gains. If you won $5,000 and lost $7,000, you can deduct only $5,000 in losses, leaving you with zero net gambling income to report.

To claim losses, you must itemize deductions on Schedule A of your tax return rather than taking the standard deduction. This means your total itemized deductions must exceed the standard deduction for your filing status to make it worthwhile. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly.

You need documentation to back up your deduction. Keep receipts, tickets, credit card statements, and a log of dates, locations, and amounts won and lost. The IRS can ask for this evidence if you are audited, and without it, the deduction will be disallowed.

State taxes on gambling winnings

Most states tax gambling winnings in addition to federal tax. Some states, like Nevada and Montana, do not have a state income tax, so you owe only federal tax on your winnings. Other states tax all gambling winnings at their standard income tax rate, which ranges from roughly 1% to 13% depending on the state and your income level.

A few states tax certain types of gambling differently. For example, some states tax lottery winnings at a flat rate while taxing casino winnings at the regular income tax rate. New York taxes lottery winnings at 8.82% plus federal tax, making a large lottery win significantly more expensive than a casino win of the same amount.

When you win at a casino or track in a state other than your home state, you may owe tax to both states. Your home state typically taxes all your income, including out-of-state gambling winnings. The state where you gambled may also withhold tax at the time of the win. You can usually claim a credit on your home state return for taxes paid to another state, but the rules vary.

Withholding and estimated tax payments

Casinos and other venues are required to withhold federal income tax from large wins before paying you. The withholding rate is typically 24% for most gambling winnings, though it can be higher depending on the type of gambling and the amount won. This withholding is not optional — the venue must deduct it and send it to the IRS.

Withholding is not the same as paying your full tax bill. If your total tax liability is higher than the amount withheld, you will owe the difference when you file your return. If the withholding exceeds your actual tax, you may receive a refund. Either way, you must report the full amount of your winnings on your return, not just the amount you received after withholding.

If you have significant gambling winnings and expect to owe more than $1,000 in federal tax for the year, you may need to make estimated tax payments to avoid penalties. Estimated taxes are due quarterly, and the IRS can charge interest and penalties if you underpay. A tax professional can help you determine whether estimated payments are necessary in your situation.

Reporting gambling income on your tax return

Gambling winnings are reported on Form 1040, Schedule 1, under "Other Income." If you received a Form W-2G, you report the amount shown on that form. If you did not receive a W-2G but had taxable winnings, you still report them on Schedule 1 — the absence of a form does not mean the income is not taxable.

If you are itemizing deductions to claim gambling losses, those losses go on Schedule A. You list your total gambling losses and subtract them from your total gambling winnings. The net amount is what you report as taxable gambling income on Schedule 1.

If you won money from multiple sources — a casino, a lottery, online betting — you can combine them into a single line item on Schedule 1. You do not need to list each win separately unless the IRS requests it during an audit.

What happens if you do not report gambling winnings

Failing to report gambling income is tax evasion, and the IRS takes it seriously. If the IRS discovers unreported winnings through a Form W-2G or during an audit, you will owe back taxes plus interest and penalties. The penalty for underpayment is typically 20% of the unpaid tax, though it can be higher if the IRS determines the understatement was substantial or intentional.

The IRS can go back several years to assess unpaid taxes. Generally, the statute of limitations is three years, but if you underreported income by more than 25%, the IRS can go back six years. If the IRS suspects fraud, there is no time limit.

Even small wins add up over time. If you gamble regularly and do not report your winnings, the cumulative amount can trigger an audit. The IRS uses computer matching to cross-reference W-2G forms with tax returns, so discrepancies are often caught automatically.

Professional gamblers and self-employment tax

If you gamble professionally — meaning gambling is your primary source of income and you do it with the intent to make a profit — the IRS may classify you as self-employed. Professional gamblers must report their winnings as self-employment income and pay self-employment tax (Social Security and Medicare tax) in addition to income tax.

The distinction between a hobbyist and a professional gambler is not always clear. The IRS looks at factors like whether you gamble regularly, keep detailed records, have a separate business account, and show a profit in most years. If you are unsure whether you may have access to as a professional gambler, consult a tax professional before filing.

Professional gamblers can deduct gambling losses more flexibly than hobbyists. They can deduct losses against other income, not just against winnings. They can also deduct business expenses like travel, meals, and equipment. These deductions can significantly reduce your tax bill if you may have access to as a professional.

Frequently Asked Questions

Do I have to report small gambling wins?

Yes. All gambling winnings are taxable income, regardless of size. If you won $50 at a slot machine or $100 on a scratch-off ticket, you must report it on your tax return. The IRS does not have a minimum threshold for taxable gambling income, though venues only file Form W-2G for wins above certain amounts.

Can I deduct losses from gambling I did not report as winnings?

No. You can only deduct gambling losses if you also report your gambling winnings. If you had losses but no winnings, you cannot deduct the losses. You must report both winnings and losses on your return to claim the deduction.

What if I won money from an online gambling site that did not send me a Form W-2G?

You still must report the winnings on your tax return. The absence of a Form W-2G does not make the income non-taxable. The IRS expects you to track and report all gambling income, whether or not a form is issued. Keep your own records of wins and losses from online platforms.

Do I owe taxes on gambling winnings if I am not a U.S. citizen?

Yes, if you are a resident alien or have a Social Security number, you must report gambling winnings to the IRS. Non-residents may be subject to different withholding rates and tax rules. If you are unsure of your tax status, consult a tax professional who handles international tax issues.

Can I use gambling losses to reduce my taxable income from my job?

No. Gambling losses can only offset gambling winnings, not other types of income like wages or salary. If your gambling losses exceed your winnings, you cannot use the excess loss to reduce your income from employment or investments.
