Key Points:
- *Any* casino wins, regardless of size, are taxable (whether you receive a W2G or not).
- A W2G will be generated and reported to the IRS for any slot win of $1,200 or more.
- Legislation has been proposed to increase that $1,200 threshold, but it hasn’t gained traction.
If you have an upcoming trip to a casino, you’ve had dreams of hitting that big jackpot.
What most fail to consider, however, are the tax implications caused by a big win.
I want to give you a high-level understanding of taxes as they relate to slot and casino jackpots in Vegas or anywhere in the US.
Keep in mind, I’m a Vegas aficionado, not an accountant. Talk to a CPA if you need real-world advice.
When do you need to pay taxes on gambling wins?
This answer is simple: anytime you win. That goes for any gambling income you earn, whether on the slots, table games, lottery tickets, horse racing, or a friendly bet with your neighbor Craig.
If you profited, even $5, the IRS wants its cut.
Gambling wins are added to your income, and taxes are paid at your marginal rate. There’s no special gambling income tax rate; It’s simply treated as income, just like that earned at your day job.
Tax professionals recommend keeping a log of gambling activity to include dates, games played, and profit/loss over the session so that you have a record of your activity over the year.
Although the IRS wants a cut of ANY gambling win (whether big enough to generate a tax form or not), most recreational gamblers don’t keep a detailed record of their wins/losses for tax purposes (tisk, tisk, tisk). Most are more concerned about wins large enough to trigger a mandatory W2-G.
A W2-G is a federal tax form that details income from gambling activity that the casino generates at certain win thresholds (discussed below) and is reported to the IRS.
Since the generated W-2-G is sent to the IRS, players risk an audit if the income isn’t declared on that year’s tax return.
Keep in mind, gambling wins can be offset on your federal taxes by losses incurred over the year, but only if you itemize.
Since the standard deduction was recently increased, fewer people itemize, making it a challenge for some to avoid paying taxes on their winnings.
While taxpayers used to be able to write of 100% of their losses to offset wins, the “Big Beautiful Bill”, passed in 2025, limits that deduction to 90% of losses.
Disappointingly, that means gamblers could end up paying income tax on income that doesn’t exist, starting in 2026.
While NV Rep. Dina Titus has introduced legislation to restore the 100% deduction, it has failed to move forward as of December 2025.
How much do you have to win to trigger a W2-G Tax Form at the casino?
Depends on the game. The IRS has set the following guidelines for common games:
- $1,200 bingo or slot win (not reduced by the wager).
- $1,500 or more from a keno game (reduced by the wager).
- $5,000 or more from a poker tournament (reduced by the buy-in).
- $600 or more at the horse track if your win is 300x greater than your original bet.
Will the casino withhold money from your slot jackpot?
The casino is not required to withhold taxes from your jackpot win, provided you furnish a correct taxpayer identification number.
Instead, you’ll pay taxes on that income at the end of the year. Many casinos, however, will withhold a percentage of your win if requested to help you avoid a big tax surprise at the end of the year.
If you’re unable to provide a tax identification number (social security number), your jackpot will be withheld at a rate of 24% (reduced from 28% as of 2018).
Foreign gamblers who hit jackpots are always withheld at a rate of 30%, although nationals of select countries can recoup all or a portion of that withholding.
Will a W2-G generate as a result of a large table game win?
Nope. While income earned on games like Blackjack, Roulette, Craps, etc. is taxable, no win threshold would trigger a W2-G, nor will your win be proactively reported to the IRS.
The exception to this would be if you hit a side bet or progressive jackpot that is 300x the bet made.
Could the threshold for generating a W2-G be increased?
Legislative Efforts
The current $1,200 threshold was established in 1977 and has not been adjusted for inflation since. Obviously, the value of $1,200 in 1977 is very different than today.
A bipartisan group of legislators in the U.S. House of Representatives that includes Dina Titus (D-NV) has introduced bipartisan legislation that would increase the win amount needed to trigger a W2-G to $5,000 from the current $1,200 benchmark, but efforts have been unsuccessful to this point.
Titus points out that “The current threshold for reporting slot winnings was set at $1,200 in 1977 and has not been updated in the 45 years since. If indexed for inflation, the threshold would be around $5,000. Due to inflation, the number of jackpots hitting that threshold, locking up the slot machine, and necessitating tax paperwork, has increased dramatically.
Regulatory Developments
The IRS advisory council recently suggested increasing the threshold from $1,200 to $5,800. Encouragingly, the panel even suggested the IRS itself could make the policy changes without supporting legislation…. But this has yet to materialize.
At the end of the day, if you’re worried about taxes, something good has happened. Congrats! Let’s hope that in the coming years, the threshold for triggering a W2-G on slot wins can be increased to lessen the burden on both players and casinos alike.
If you are curious about gambling taxes or have specific questions about your situation, I recommend connecting with a tax professional to discuss the matter further.
