I started an LLC last year with my father, elected MTM for securities only, and traded 90% futures. I'm getting ready to file an LLC return -- from what I understand it's a partnership return (for a multi-member LLC) which passes through gains/losses. My question is -- are there any "gotchas" for filing the return? The LLC made about 40 stock trades (mostly in December when I started trading a new system for equities) and around 1000 futures trades, most not held overnight (the longest holding period for a future was about 6 days). I'd like to avoid paying $1500 to a CPA when it's mostly single line item futures trades, but on the other hand I want to make sure the LLC gets trader status.
