Tax Question-about money in account not cashed out

Greetings,

I'm sure many of you are now becoming vigilant regarding tax questions as the new year approaches. I certainly have been feeling some (healthy) anxiety. I have a tax question for anybody with experience/expertise. This problem is faced by many I'm sure. Assume player 'X' has $1,000 in a PP account (or whatever amount of winnings). At what point is this money taxable? Is it taxable as the New Year rolls over simply because it's sitting there? Is it taxable at the point it's cashed out? Is it taxable the minute the check is cashed and hits your bank account? Is it taxable the minute it's won and hence if it's cashed out in 2006 it doesn't get taxed again? I guess the issue of double taxation is a concern. Any feedback would be greatly appreciated.
