Every year, about 40% of American adults visit at least one of the casinos that are located in Las Vegas, Nevada, in Atlantic City, New Jersey, or in one of the dozens of places in between, not to mention on the web. A lucky few take home a lot of money.

Alas, If you win big while gambling, you do not get to keep every penny. Gambling winnings are fully taxable, and the Internal Revenue Service (IRS) has ways of ensuring that it gets its share. And it's not just casino gambling. Winnings from lotteries, horse races, off-track betting, sweepstakes, and game shows are taxable as well.

If it's any consolation, gambling losses are deductible if you itemize your deductions. But they're deductible only up to the amount that is offset by your winnings, and you must be able to prove it through records of your winnings and losses.

Before heading for the Las Vegas strip, make sure you understand the tax law as it relates to gambling to avoid a mess with the IRS down the road.

Key Takeaways

  • If you win above a certain amount, the payer will deduct 24% from your winnings on the spot.
  • When you file your annual tax return, you'll record your winnings and your tax payments. You may then have to pay more, or get some of your money back, depending on your tax rate.
  • You can deduct gambling losses but only up to the amount of winnings that you report. Keep good records!

How Gambling Winnings Are Taxed

If you win a substantial amount of money in any legally operated game of chance, the payer of your winnings will deduct 24% of the total for taxes and will give you a copy of IRS Form W-G2 to record the transaction.

What is "a substantial amount of money" in gambling? It depends on the game. It's $1,200 or more in winnings at slot machines or bingo games, but $1,500 for keno. It's $5,000 for sweepstakes, wagering pools, and lotteries.

In any case, 24% of the amount won will be deducted from your payout and sent directly to the IRS, with Form W-G2 as the documentation. That 24% is an estimated tax. You might get some of it back, or owe more.

Taxes on winnings at games of skill like blackjack are not immediately withheld but you still are required to report the income and pay taxes on it.

Exceptions to the Rules

Casinos are not required to withhold taxes or issue a W2-G to players who win large sums at certain table games, such as blackjack, craps, and roulette, all of which are categorized as games of skill rather than games of chance.

It is not clear why the IRS has differentiated the requirements this way. Slot machines are games of chance, while table games are seen as requiring a level of skill.

In any case, when you cash in your chips from a table game, the casino cannot determine with certainty how much money you started with.

This does not absolve you of the obligation to report what you won to the IRS. You simply do it yourself when you file your taxes for the year rather than at the casino when you claim your winnings.

And make sure you kept good records of your gambling activities, losses as well as gains. If you spent $2,000 to win $2,000, you might be able to avoid paying taxes.

Reporting Gambling Winnings

When you prepare your taxes for the year in which you won a gambling payout, you'll report the income and the taxes already paid on it under "Other Income" on Form 1040.

Remember, the 24% you already paid was an estimated tax. The real amount you owe (or will be reimbursed) depends on your total income for the year.

There are currently seven tax brackets. As of the 2021 tax year, you would have to have an individual income above $164,925 (including your winnings) to owe more taxes on your winnings. If your total income was under $86,376, you may even get some money back.

Do Casinos Report Gambling Earnings to the IRS?

Yes, but there are certain thresholds that must be eclipsed to trigger a casino to report winnings. The threshold at which gambling winnings must be reported to the IRS varies based on the type of game.

At a horse racing track, winnings that exceed either $600 or 300 times your initial wager must be reported. For slot machines and bingo, all winnings in excess of $1,200 must be reported. In a poker tournament, the level is $5,000.

Taxes for Professional Gamblers

If gambling is a person's actual profession, gambling proceeds are usually considered regular earned income and are taxed at a taxpayer's normal effective income tax rate.

As a self-employed individual, the income and expenses must be recorded on Schedule C.

A professional gambler can deduct gambling losses as job expenses using Schedule C (not Schedule A).

Gambling Income Tax Requirements for Nonresidents

The IRS requires nonresidents of the U.S. to report gambling winnings on Form 1040NR. Such income is generally taxed at a flat rate of 30%.

Nonresident aliens generally cannot deduct gambling losses. There is a tax treaty between the United States and Canada. It allows Canadian citizens to deduct their gambling losses, up to the amount of their gambling winnings.

Are Gambling Losses Deductible?

You are allowed to deduct any money you lose gambling from your winnings for tax purposes.

However, gambling losses in excess of what you win may not be claimed as a tax write-off. When you lose your shirt in Vegas, there is no silver lining in the form of reduced tax liability.

Do the States Tax Gambling Winnings?

Some states require gambling winners to claim the gambling winnings in the state where they were won.

Most states tax all income earned in their state, regardless of your residency.

In addition, your resident state will require you to report the winnings but will offer a credit or deduction for taxes already paid to a non-resident state.
