Does anyone have experience with the tax reporting issues for professional gamblers? Not for me, but a friend who is playing live and online, and has been fortunate enough to have amassed a fair amount of net winnings. As I understand it, there are issues with defining "gaming sessions", and the netting of wins and losses. Any advice, direction or referral would be much appreciated. His current accountant has no experience in the area, but is aware of the some of the issues. Please email directly if not too inconvenient. Thanks for any help. dcall@sikich.com
