I only trade ES, in and out, lots, so I already get Sec. 1256, MTM, right? I also have a side business as a writer where I take deductions for publications, computer equipment, etc. I do not take the home office space allowance because when I sell the house I don't want the extra bookkeeping/accounting hassles (wife's decision). I'm not planning on raising capital from outside investors, friends and family or otherwise. So is there any benefit to getting a CTA, incorporating as a family partnership or claiming trader status on my taxes?
