My tax adviser told me I should go for a Einzelunternehmen (especially use the Kleingewerbe during the first year) because of the reduced costs (registration costs 25EUR and thats it) and not having the overhead. I’ve heard that registering a UG costs about ~500EUR + yearly costs of around 1500 EUR.
Given that this is during a beginning to try things out - without having too much money laying around to play with it.
Would definitely like to know about risks before getting myself into it.
