If I were to win say, $100,000 playing online poker, I know the government wants to tax me on that. What happens if I don’t withdraw the money from my account? Do I pay taxes on it? What if I withraw just a little bit at a time over several years, do I have to report it?
I am in the U.S (Virginia), by the way.

If you win $50,000+ from an online poker/gambling site based outside the US, is there any way to cash out the money without having to pay taxes? If not, can someone explain how taxes would work?
