DO NOT use H&R Block, you run the risk of being audited! Hire a dedicated CPA that exclusively handles trader's accounting, or has done active trader's returns before. No need to use one of these mills that "specializes" in forming uneccessary entities either! el surdo
I've been audited plenty of times. No big deal. Besides, my tax guy at H&R is their senior tax advisor and is retired from Smith Barney. If he does me wrong, I'll be back here to admit I was wrong... Anyway, GreenTraderTax.com is a ripoff IMHO. I'd have pay several thousand for them to do my taxes. Not going to happen. http://www.greencompany.com/Traders/TraderTaxPrepCosts.shtml#retainer
