Gambling losses are deductible only if you itemize deductions, and only up to the amount of gambling winnings you reported that same year

The IRS allows you to deduct gambling losses, but with a strict limit: you can only deduct losses up to the total gambling winnings you reported as income. If you won $500 at a casino and lost $800 at a poker table in the same year, you can deduct only $500 in losses. You cannot deduct the remaining $300 loss, and you cannot carry it forward to next year.

This deduction is available only if you itemize deductions on your tax return using Schedule A. Most people take the standard deduction instead, which means they cannot claim gambling losses at all. You must also have records proving both your wins and losses — receipts, tickets, or statements from the gambling venue.

Key Takeaways

  • Gambling losses reduce your taxable gambling income dollar-for-dollar, but cannot exceed your total gambling winnings for the year.
  • You can only claim this deduction if you itemize deductions on Schedule A; the standard deduction blocks it.
  • The IRS requires documentation of losses: receipts, losing tickets, casino statements, or records from the gambling venue.
  • Losses from casual gambling, sports betting, and lottery tickets follow the same rules as casino losses.
  • If you gamble professionally or as a business, different rules may explore and you should consult a tax professional.

How the IRS treats gambling winnings and losses

All gambling winnings — from casinos, online poker, sports betting, lottery tickets, or horse racing — count as taxable income. The gambling venue or platform usually reports winnings of $600 or more to the IRS on Form W-2G. You must report this income on your tax return whether or not you received a form.

Gambling losses offset only that gambling income. If you won $1,200 and lost $900, your net gambling income is $300, and that is what you owe tax on. If you lost $900 and won nothing, you cannot deduct the $900 loss at all — you have no gambling income to offset.

This is different from business losses or investment losses, which can sometimes reduce your overall income. Gambling losses are locked to gambling winnings and cannot spill over into other income categories.

Itemizing versus the standard deduction

To claim gambling losses, you must file Schedule A and itemize your deductions. The standard deduction for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly. If your itemized deductions (including gambling losses, mortgage interest, charitable donations, and state taxes) add up to more than the standard deduction, itemizing saves you money. Otherwise, take the standard deduction and skip the gambling loss deduction.

For most people, the standard deduction is larger. You would need substantial other deductions — a mortgage, significant charitable giving, or high state and local taxes — to make itemizing worthwhile. A tax professional can calculate which approach saves you more.

What records you need to keep

The IRS requires documentation of gambling losses. Keep receipts, losing tickets, casino statements, or records from the gambling venue showing the date, location, type of gambling, and amount lost. A diary or log noting each session also helps, especially for casual gambling where venues may not issue statements.

If you gambled at a casino, request a statement from the casino showing your play history. Many casinos provide this to players who ask. For online gambling, read your account history or statements. For lottery tickets, keep the tickets themselves or a record of purchases. Without documentation, the IRS can disallow the deduction entirely if you are audited.

Store these records for at least three years after you file your return. The IRS typically has three years to audit a return, though it can go back longer if it suspects underreporting of income.

Gambling losses and professional gamblers

If you gamble as a business or profession — meaning you gamble regularly, keep detailed records, and treat it as your primary income source — different tax rules may explore. Professional gamblers may be able to deduct losses differently and claim other business expenses like travel or equipment.

The IRS distinguishes between casual gambling (a hobby) and professional gambling (a business). This distinction affects how you report income and what deductions are available. If you earn significant income from gambling, consult a tax professional or CPA who can review your specific situation and advise whether you may have access to as a professional gambler.

State taxes and gambling losses

Some states allow gambling loss deductions on state tax returns, while others do not. A few states — including New Jersey and Nevada — have specific rules for gambling losses. Check your state's tax authority website or speak with a tax professional to understand your state's rules.

Even if your state does not allow a deduction, you still owe federal tax on gambling winnings. Federal and state rules are separate, and you may owe tax in one jurisdiction but not the other.

Common mistakes to avoid

The biggest mistake is claiming gambling losses without itemizing. If you take the standard deduction, the gambling loss deduction is not available to you — you cannot claim it on top of the standard deduction. Calculate both scenarios before you file.

Another mistake is deducting losses that exceed winnings. The IRS will disallow any loss amount above your total gambling income for the year. If you won $400 and lost $1,000, you can deduct only $400.

A third mistake is failing to report gambling winnings. Even if you lost money overall, you must report all winnings as income. The IRS receives reports from casinos and betting platforms, and unreported income triggers audits.

Frequently Asked Questions

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

No. Gambling losses are a deduction you claim on Schedule A when you itemize. If you take the standard deduction, you cannot claim gambling losses. You must choose one or the other.

What if I lost more than I won?

You can deduct losses only up to your winnings. If you won $300 and lost $800, you deduct $300 and report $0 gambling income. The extra $500 in losses cannot be deducted or carried to next year.

Do I have to report gambling winnings if I lost money overall?

Yes. All gambling winnings are taxable income and must be reported, even if your total losses for the year exceed your winnings. The IRS requires you to report the wins separately from the losses.

What counts as gambling for tax purposes?

Gambling includes casinos, poker, sports betting, horse racing, lottery tickets, online gambling, and raffles. Any wagering where you risk money for a chance to win counts as gambling for tax purposes.

How long do I need to keep gambling records?

Keep records for at least three years after you file your return. The IRS can audit a return within three years in most cases. If you claim large losses, keep records longer in case of a deeper audit.
