Let's say Bob has tax residency in France and wants to move it to a different EU country.
The main idea is to get rid legally of tax residency in France in a quick and cheap way, so the new country should provide all needed paperwork/certifcates to report France tax authorities with no pain...
Do you know any EU country to operate as freelance or sole proprietorship with a low tax burden?
Ideally with a flat tax no higher than 15%.
