This is a niche question to fellow HNers in Austria:<p>I'm in the process of starting an online side-business and am unsure which legal entity to choose. Currently, I am doing my consulting as EPU but for an online company I'd rather split my private person and the company as much as possible (clearer separation of finances, less legal attack surface). But a GmbH in Austria for a ramen-profitable side-project is expensive!<p>How did you get started? Do you have experience with German UGs or GmbHs? I dread the cross-border tax issues. Thanks!<p>UPDATE: Since I last discussed this with my tax advisor, things seem to have become simpler: this site [1] claims total founding costs of a German UG for an Austrian to be ~800 EUR, with yearly costs of ~250 EUR for tax advisory. Still, I'd be very interested if anyone has first-hand experience with such a setup or similar.<p>[1] http://www.ugstattltd.at/unsere_leistungen.htm
