In Greece, heirs are divided into 3 categories; main category includes spouse, children, grandchildren and parents.
Inheritance tax has 3 scales and is calculated on property tax value (not market value).
Property with tax value under €150 000 is tax free. Exceeding €150 000 is taxed by 1% and €300 000 by 5% respectively. 10% on the share above €600 000.
Example: inherited property with tax value of €800 000 is taxed 1500 +15 000+ 20 000 = €36 500. Given example concerns main category only.
