I declared MTM in 2007 and will be filing my 2007 taxes tomorrow(deadline for extension). I have a large net operating loss. I'm trying to make sure I do everything right so that the IRS doesn't try to deny my NOL. I went through my broker's P&L statement and the combined the 1099 statement they sent. The numbers match up. I am wondering if there is any reason for me to buy Tradelog or Gainskeeper? Right now I am planning on just using any old basic tax software for the rest of my return, printing it out, and then attaching a huge stack of papers (all of my trades, forms 3115,4797, footnotes) and mailing it certified mail. Anyone know if there is tax software that can completely efile thousands of trades, plus the other forms and footnotes? Would the IRS be more pleased if I used tradelog or gainskeeper, or doesn't it make a difference since all my trades match up? BoughtRobert Green's book from a bookstore quite awhile ago and read it, so I'm not new to this stuff but I want to make sure I do everything perfectly. Will be staying up all night tonight checking my work.
