Somewhat random suggestions to follow but I've been researching this a lot myself. I'm personally looking for an EU country with a low corporate tax rate and zero capital gains tax (for early retirement). I've narrowed that down to Cyprus, Switzerland, Georgia, Portugal and Poland.

Switzerland is probably the winner but it is much higher COL (though you can get San Francisco salary there for a much better quality of life).

I actually currently live in Berlin now and I have to admit that the more I research, the more I find that Germany isn't so bad of an option at all. If you want children/family in the future, Germany has much better benefits than Switzerland.
