Okay, So i am getting conflicting advice here. I am a non-resident alien, executing my trades from Europe, trading the US markets. Last year, I was a member of a trading LLC. This account is a "retail-subaccount", and I am being paid out on a K-1. I have to pay US taxes on that K-1, correct? or do i simply pay taxes to my goverment and ignore the US side? Any advice would be deeply appreciated.
