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.
Is the exception still valid? I thought the new central regulation in effect removed those (if the region has exceptions then you pay federal "solidarity" tax). They introduced it to fight Madrid's and Andalusia's exemptions.
I investigated it some time ago though when I was considering moving to Andalusia so maybe something changed.
