That is only if you haven't accumulated wealth yet. The combination of quite high capital gain tax with sky high wealth tax, pretty high income tax isn't very attractive if your plan is to accumulate some wealth. If you just want to make enough every year to live there I guess it's reasonable though.

I future-proofed myself by moving to a region with a €3M exception. So that I have a long way to go before paying wealth tax.

CGT is progressive and around 20%, compared to other European countries that is fairly average. Some Eastern European countries are at 15%, Belgian is going to 10%, Switzerland differs per canton.

Also, no CGT for fresh immigrants if you are able to use the Beckham law.
