One interesting aspect of Estonia is the Digital residency: if are you are allowed to live in Estonia (EU citizen or equivalent) you can be asked to be considered a “digital resident”. That means that you can choose to pay tax there. The main advertised advantage is that all your paperwork, including your company’s, can be done entirely on-line, using a super-secure ID card.

That comes with the (welcome) assumption that you are not going to speak Estonian, and would prefer strong encryption and associated protocols.

I haven’t tried it myself, but my experience of paper-based administrations vs. Finnish and Swedish (far more IT-friendly) is night and day.
