Millions of Americans gamble every day and in all sorts of ways. Examples include playing games of chance at casinos, placing wagers on horse races, betting on sports, and buying lottery and raffle tickets. Sometimes you win, and sometimes you lose. But both have tax consequences.
All Gambling Winnings Are Taxable Income
All gambling winnings are taxable income—that is, income subject to both federal and state income taxes (except for the states that have no income taxes). It makes no difference how you earn your winnings, whether at a casino, gambling website, church raffle, or your friendly neighborhood poker game.
It also makes no difference where you win: whether at a casino or other gambling establishment in the United States, including those on Native American reservations, in a foreign country such as Mexico or Aruba, on a cruise ship, Mississippi riverboat, or at an online casino hosted outside the U.S.
Gambling winnings include not only the money you win but the fair market value of any prizes or “comps” you receive as well.
All Winnings Must Be Reported
If, like the vast majority of people, you’re a casual recreational gambler, you’re supposed to report all your gambling winnings on your tax return every year. You must report all gambling winnings on Form 1040 or Form 1040-SR (use Schedule 1 (Form 1040)).
You Can Deduct Gambling Losses (If You Itemize)
Although you must list all your winnings on your tax return, you don't necessarily have to pay tax on the full amount. You are allowed to list your annual gambling losses as a miscellaneous itemized deduction on Schedule A of your tax return. If you lost as much as, or more than, you won during the year, your losses will offset your winnings. For example, if you lost $10,000 and won $8,000 during various trips to casinos, you can deduct $8,000 of your losses, which is the amount up to your gain. What about the remaining $2,000 of unclaimed losses? It simply disappears. You can't use it to offset your gambling gains in other years.
However, starting January 1, 2026, the One Big Beautiful Bill Act limits gambling loss deductions to 90% of losses. Under current law, taxpayers can deduct 100% of gambling losses, but only up to the amount of their gambling winnings. So, for example, if you win $100,000 in 2026 and have $100,000 in losses, you can deduct $90,000. The remaining $10,000 is taxable income, even though you actually broke even.
However, you get no deduction for your losses at all if you don’t itemize your deductions. You should only itemize if all your personal deductions, including gambling losses, exceed your standard deduction for the year.
Fewer People Now Itemize
The Tax Cuts and Jobs Act (TCJA), the massive tax reform law that went into effect in 2018, made it much harder for most taxpayers to itemize. As a result, only about 11% of all taxpayers are able to itemize, down from one-third in prior years. That's because the TCJA roughly doubled the standard deduction, and the One Big Beautiful Bill Act made the larger standard deduction permanent. These laws also eliminated many personal deductions, such as the deduction for unreimbursed job expenses and many others.
The only major personal deductions remaining are those for home mortgage interest, state and local taxes (capped at $40,000 per year (2025)), charitable contributions, and unreimbursed medical expenses (over an AGI threshold). If these expenses, in addition to your gambling losses, don't exceed your standard deduction, you won't be able to itemize. So, you'll get no deduction for your gambling losses. As a result, you'll have to pay income tax on all your gambling winnings, with no deduction at all for your losses. A true tax disaster. This makes it very important to keep track of all your gambling losses.
Casinos Report Certain Winnings to the IRS
Casinos, race tracks, state lotteries, bingo halls, and other gambling establishments located in the United States are required to tell the IRS if you win more than a specified dollar amount by filing a tax form called Form W-2G with the IRS. You’re given a copy of the form as well.
When a W-2G must be filed depends on the type of game you play and how much you win. For example, according to the IRS instructions for Form W-2G, the casino must file a W2-G if you win $1,200 or more playing slots or bingo; but only if you win $1,500 or more at keno. If this income isn't listed on your tax return, you’ll likely hear from the IRS.
Keep Records of Your Wins and Losses
If you’re audited, your losses will be allowed by the IRS only if you can prove the amount of both your winnings and losses. You’re supposed to do this by keeping detailed records of all your gambling wins and losses during the year. This is where most gamblers slip up—they fail to keep adequate records (or any records at all). As a result, you can end up owing taxes on your winnings even though your losses exceed your winnings for the year.
The IRS says that whenever you gamble, you should keep a diary or logbook recording the:
- date
- name and address (or location) of the gambling establishment
- type of wagers you made
- amounts you won or lost during each gambling session, and
- names of any other people with you during the session. (Rev. Proc. 77-29).
Your log can be handwritten in a notebook, appointment book, calendar, or any other piece of paper in which you write down how much you won or lost for each gambling session. You can also purchase a gambling logbook.
It is wise to have documentation to back up your gambling log. This should include:
- evidence that shows that you really were at the casino or other gambling establishment at which you claim you gambled—for example, dated parking receipts, hotel reservations and billing statements, and dinner and snack shop receipts
- copies of all IRS Form W-2G casinos or other gaming establishments gave you when you won more than a threshold amount
- Copies of IRS Form 5754, Statement by Person(s) Receiving Gambling Winnings, that is used when you win more than a threshold amount on a group wager
- wagering tickets
- canceled checks you wrote to pay for wagers
- credit records showing advances of credit to you from casinos or other gaming establishments
- bank withdrawal records (including ATM receipts), and
- statements of actual winnings or payment slips provided to you by gambling establishments.
Are You a Pro?
If you gamble full-time to earn a living, you might qualify as a professional gambler for tax purposes. Professional gamblers get many tax deductions and other tax breaks that casual recreational gamblers don’t.
Unlike casual gamblers, professionals only report on their tax returns (IRS Schedule C) their net income from gambling. That is, they get to subtract their losses (and other expenses) from their winnings. Professional gamblers whose expenses are equal to or greater than their winnings will have zero gambling income to list on their tax return and pay tax on.
Also, professional gamblers get to deduct their business expenses from their winnings. These include not only their gambling losses, but expenses such as travel, hotels, dealer tips, and internet and cell phone costs. Casual gamblers get no such deductions. But unlike all other businesses, professional gamblers aren't allowed to deduct their losses or expenses such as travel against non-gambling income.
Gambling professionals who earn a profit might qualify for the pass-through tax deduction. This deduction permits business owners to deduct up to 20% of their net business income from their income taxes.
