Finally, pick up JK Lassers Tax Guide or Ernst and Young's tax guide and read through the pertinent points. They are only 15$ or so and will keep you out of trouble. The IRS has many publications on topics that are downloadable in Adobe format. I try and stay away from some of the "speciality" publications as SOME are a little expensive and take some aggressive positions that don't always jive with the internal revenue code.
I MOVED THE ABOVE UP SINCE THE REST OF THE MESSAGE IS LONG.
I worked for a big 5 accounting firm in their tax dept for a while before switching to consulting. Needless to say I was not impressed with the way taxes (business or personal) were handled. It seems to me that unless you have a lot of money you are basically paying for keystrokes and not tax planning.
To give you to instances that came up for me recently, my buddy that I mentioned in another post asked me about the MSA rules for health insurance, he then took the idea to his CPA who said "that's a good idea". For the money he is paying this guy that is the sort of thing I would want a CPA bringing to me. My girlfriend's mother could not deduct expenses on a rental property because she did not advertise it for rent while fixing it up. These are the types of things if I was meeting with a CPA I would want presented to me as they relate to trading.
You could call around to CPA firms and meet with people face to face if you can not get a referral from a trader friend who is satisfied. And I would weigh what he/she says with what your objectives are and how much they cost. Probably more specializing in a bigger city, but finding a true specialist may still be tough.
For instance based on what you said you need to start making at least minimal estimated payments, with your next payment due June 15. This goes on 1040-ES, TN has no State tax but GA does.
Next would be something like Mark to Market election. Based on your situation, I would wait on this until you are 100% sure this is what you want to do. This goes on 3115, but a CPA might suggest that you get a letter ruling from the IRS before filing. This would be written commentary from the IRS that based on your trading information on wether MTM is appropriate.
Business expenses and section 179 should be discussed, how much "trading" income you have, and how to they propose handling it?
If they start talking about Nevada Corporations or Offshore Accounts I would run the other way.
So if your income justifies it, I would pay a little to lay out your situation and find someone who wants to work for you. If they just want your "Shoebox" of receipts on April 1, you are as well served going to Jackson Hewitt or HR Block in my opinion. I use the over the counter software, and other than a few bugs (like my roth conversion amount did not flow correctly) it is just as good. In fact, at the aforementioned big 5 who had their own software I had those type of issues, so a manual check is always necessary.
