Do I incorporate? Where? U.S.? As what? Sole proprietor? Any foreign tax issues? I'm running mid-six figures of my own money, shorting futures options, equity and index options, some futures. (Looking mainly to put profits in a tax-deferred retirement account or fully deduct losses; I assume trader status is no problem, as I won't be working elsewhere, except for some freelancing and consulting, and will be trading almost daily, maybe 10-15 trades; I also assume I don't get the overseas income tax break because this is not "earned" income.) Thoughts? Caveats? Advice? Go directly to a professional for help?
