I am heading to Las Vegas later on this week for the first time and I am hoping to play in one or two Poker Tournaments. I read somewhere that as a foreigner (I'm from New Zealand) if I'm good enough/lucky enough to win some prize money, there will be withholding tax taken out of that. Can someone tell me what % is taken in tax and how easy it is to claim that back. In New Zealand all gambling is taxed at the source so all wins are tax free. Thanks.
