Around half of it is what you get out, +/- around 5% depending on whose the more earning party.
In Germany if you marry you get the option to either both stay Steuerklasse 1/4 or you get to downgrade one which has to pay a little less taxes while the other one stays higher taxed.
Patriarchially that's why married women always earn less in their Steuerklasse 5 (even if they would be paid the same) because they pay the more taxes, so that the husbands in Steuerklasse 3 pay less taxes.
Not making this up, in case you want to smash that slur button.
Oh, and it also is only useful when one party (statistically the husband) makes 60% or more of the combined income because all untaxed Freibeträge are always accounted to the one with the better income in a Gemeinsamer Güterstand.
Not entirely true. In the end, you pay taxes from the yearly household income and the tax class does not change that. Tax class can only regulate how much of that you pay per month during the year. If you pay excess, you get it back with next year’s tax return. If you paid less than you had to, you’ll have to pay that difference. It makes zero sense to switch to 3/5 if you earn the same - literally zero benefit.
