I'm trying to calculate how much taxes my husband and I would pay if we relocated to Germany, and there is this website that claims to help: https://www.brutto-netto-rechner.info/

Except that the amount of taxes is so huge that I am not sure if this website works!

Are there any Germans on the Fediverse who could tell me if this website really shows a realistic amount of taxes to pay? (I've selected category IV)
