Taxing poker will be tough. What if u lose like $2k over the space of a few months and then at the end win a tourney for 2k. So your going to pay tax on this $2k even though you arent any better off. What if you only win $1K so your paying tax on this $1k even though your still in the red $1k. You should only have to pay tax on your profits. And there is no easy way to keep track of that that cannot be easily manipulated
