Quote from traderstatus:
The Tesser Book is the original and only trader's tax book found in book stores. But unfortunately that book is not a "how to" for LLC tax compliance.
Many traders make more in one morning of trading than even the most expensive CPA or Tax Attorney might charge for a once-a-year tax engagement. With that in mind, time may be better spent seeking a good trader's tax advisor than reading up and doing it yourself!
