I have been paper trading eminis for some time now and want to jump into doing it for real. I live in New Zealand and want to know how I should setup to best take advantage of being outside of the US. People jokingly said that I should set myself up as a Cayman Island registered company, but is this really an option? I don't mind being registered as a LLC company somewhere else but need to know what's actually involved as far as annual accounts/tax obligations, paying of taxes etc. Does anyone know how the brokerages (I might go with IB) feel about companies setup outside the US?
