Did you know that you can win $50,000 playing blackjack and it is not usually a taxable transaction for the player. The casino probably has to pay taxes on their blackjack winnings but that's not your problem. However if you hit a slot machine jackpot of $1,200 or more than you have to pay taxes on that. Some other table games with long shot payoffs of 1,000 to 1 have taxable consquences if you win big but not if you win big in blackjack.
