Somebody had posted here a while back I think it was Mickey about a book called Tax Help for Gamblers by Jean Scott. I read it some months back and an excellent book. She just came out with a new edition which includes information about the how the recent tax law changes affect gamblers. Just bought it on Kindle and started reading it and even though most of the information is the same as the last edition the refresher is great and the information about how the recent changes relate to gamblers is very valuable. Would say it’s a must read for anyone with significant gambling income.
