At home I want to play in the tournaments at Seneca Casino in Niagara Falls NY but they hold back 30% from all winnings. They have a bounty tournament that pay's $25 for a bounty and they even take 30% off that. Needless to say I don't partake in these tournaments especially when I can sit at the cash game and no matter what I cash out for there is no withholding tax. They tell me its a federal law but when I was in Vegas over Christmas I played tournaments at the Mirage and they never withheld anything. I am just curious what your home base poker room's policy is?
