Setting up a sole trader business and becoming a resident in Poland - Procedure? [32]
I wouldn't be surprised if you would be in more trouble than just a fine. Since this whole scheme is purposely set up to mislead the tax authorities, it could also lead to criminal charges. Guus Hiddink (the football coach) was (in The Netherlands) convincted to a six-month suspended jail sentence for wrongly claiming to be a tax resident of Belgium in stead of the Netherlands. And Hiddink had actually some ground to claim he lived in Belgium (he had a house in Belgium where he lived now and then etc.), so the punishment could be even higher for those who try James' suggestion and get caught...
I've found this information on a German website (daad.pl/de/19221/index.html). Unfortunately, my German is far from perfect, but I think it means that there are 4 steps you should take, in this order:
1. Register your place of residence at the City Council;
2. Register yourself at the Province Department;
3. Request a PESEL-number at the City Council;
4. Complete your registration at the Province Department.
If this is correct, then I can see how it works. You could register your business in between step 3 and 4, assuming you don't have to provide (and document) your reason of stay at step 2. Then you have the documentation of your self-employment needed to finish your registration at the Province Department at step 4.
Not sure whether this is correct, but if someone knows, I'll happily hear so.
