I could use some pointers from anyone who receives a K-1 each year (i.e. traders with the LLCs like Bright, VTrader, Assent, etc). 1. Say I begin trading with an LLC tomorrow. I realize I personally missed the April 15 Mark to Market election date, but does that matter for me? I seem to be under the impression that the LLC as a whole has elected the MTM for all of their subaccounts so it's not an issue for me. Please correct me if I'm wrong here. 2. As far as business expenses (computers, internet, financial publications/software, etc) go, can I personally deduct them at the end of the year? Or is this something that can only be done if I'm a sole proprietor and not a part of a larger LLC. 3. How do these LLC's handle your tax reporting, if at all? Do they just send you difficult, tedious trade statements at the end of the year that you are responsible for taking to your personal accountant to figure out? What kind of record-keeping should I keep personally or do the various LLC's do a good job of aggregating everything and just rely on me to bring the tax info to an accountant? Thanks in advance for the help!
