I just did some calculations on income taxes and social security that would be due in PT as a freelancer / self employed, maybe someone is here and can confirm this (if you are already being taxed in PT you might know):
24000€ yearly salary
Simplified regime:
75% of 24K tax relevant: → 18000€ as tax base:
3845€ income tax due (tax brackets up to 28.5%)
+
Social security:
only 70% of 24000€ relevant for SS → 16800€ as base
21.4% SS rate for self employed = 3595€
BUT: self employed workers can decrase SS by 25%: 2696€ Social Security due
