When Casinos Report Winnings

Other gambling winnings, like table games or sports bets, have a lower trigger: $600 or more in payout, and at least 300 times the amount wagered. This means a $3 bet winning a $1,500 prize would trigger Form W-2G reporting.

The Thresholds by Game

The $1,200+ threshold applies to both slot machines and bingo winnings. This is true even if a player cashes out their day's playing for a lesser won amount.

Keno winnings above $1,500 require a W-2G, with the net amount reported. That is, the payer subtracts the wager from the payout.

Some state regulators note that state regulators have been stricter than the $1,500 limit, requiring documentation for keno wins over $1,200. Winnings over $30,000 are reported by most Nevada casinos.

Other wagering winnings, which may be from table games or sports bets, have a $600 threshold. But that wager has to be at least 300 times smaller than the payout. In other words, a $10 wager can't trigger this requirement, even with a $600 jackpot.

Why One Big Day Can Still Produce No Form

Many slots and table-game players expect to get a W-2G form if they have a big day of winnings. But the IRS treats each win separately, not the day's total.

This means a slots winner can have a $1,500 winning streak and still not get a Form W-2G if each jackpot is over $1,000 apiece. The player would separately report their gross gambling winnings on their 1040 tax return.

A professional keno payer might get four W-2G forms from a casino, due to four separate wins above $1,500 each, even if they didn't net $100 in cash for the day. The bookkeeper must furnish a separate form for each jackpot, without offsetting other wagers.

The IRS requires casinos to report winnings on Form W-2G and may withhold federal income tax.

Withholding and Identification

If the winner supplies a taxpayer identification number (TIN) - usually a Social Security number - the payer may withhold tax on the spot.

Tax experts note non-U.S. players in particular often don't comply with TIN requests from their casino in Las Vegas or elsewhere. This doesn't relieve the casino of its reporting obligations. Instead, the payer files Form W-2G with backup withholding. The IRS assesses penalties on both the payer and recipient.

Backup withholding also applies to domestic recipients who don't provide the casino with a current, valid tax identification number.

What the Winner Gets

The winner of a big jackpot will get two copies of Form W-2G, notes the IRS. Form 5754 goes to the IRS to document that the form has been provided to the winner, and formalizes that the payer investigated the recipient's identification.

Gambling winnings, whether reported on a W-2G or not, are still considered taxable income, the IRS adds. Winning for a keno player or slots spinner above or below the W-2G threshold is still taxable.

When tournament poker players file their tax returns, Tax rules specify, they can - and often should - apply their losses as an itemized deduction. Losses can only offset other gambling income, not other income, as Internal Revenue Code 165(d) specifies.

Similarly, a recreational player winning less than the threshold can treat their losses as an itemized deduction - but not against their gambling wins. If the taxes on gambling income exceed this amount, the excess can only be offset against other income, like wages, interest, or dividends.

The Mismatch Between Popular Summaries and the IRS Text

The reporting thresholds in IRS instructions for 2026 reflect standards set out in prior years. Many online summaries of gambling tax rules repeat the older thresholds, wrongly claiming indexed inflation adjustments bump slots and bingo to a $2,000 requirement. But the IRS document makes no such claim. It clearly requires Form W-2G when the gross payout is $1,200, without specifying any subsequent inflation bumps.

Whether because of confusion with the old thresholds or some other reason, many taxpayers wrongly expect a W-2G form to arrive with their winnings. A recent instance: an expat poker pro won three micro-stakes tournaments in three consecutive days, barely clearing the $5,001 requirement to get a W-2G each time, as reported in Card Player. None of these tournaments were reported for income tax purposes, as the $5,000 requirement represents net winnings after the buy-in, which aren't included in reportable income.

The Form's Origins

The IRS began to require winnings over a certain size to be reported way back in 1937, the five-year anniversary of the Revenue Act of 1933. That provision covered race winnings over $2,000. This size was out of reach for the average individual of the time, given those winnings worked out to more than $47,000 in 2026 dollars.

The withholding system for casinos emerged two decades later, after legacy hotels in Reno and Las Vegas were ordered dissolved. The IRS increased its regulatory focus on casinos' financial transactions - starting with withholding at 25%, the same rate as interest and capital gains. The rate was later reduced to 20%.

The current form was rolled out for payouts in 2003, as the IRS modernized its Form 1040 system.

Smith PredictQ protects its own financial information using a modernized W-2G for internal reporting, confusing investors. But Smith's investors remain the only audiences that show demonstrable confusion over the form. Capital markets professionals advised to monitor Smith closely, as its handling of financial reporting remains unpredictable.
