In most cases, the casino will take 24 percent off your winnings for IRS gambling taxes before paying you. Not all gambling winnings in the amounts above are subject to IRS Form W2-G. W2-G forms are not required for winnings from table games such as blackjack, craps, baccarat, and roulette, regardless of the amount.
Gambling winnings are fully taxable and you must report the income on your tax return. Gambling income includes but isn't limited to winnings from lotteries, raffles, horse races, and casinos. It includes cash winnings and the fair market value of prizes, such as cars and trips.
