As I understand it, there are parts of France that spent time as parts of Germany and are still somewhat culturally German that do church tax in a similar way - much of what was Alsace-Lorraine (Elsaß-Lothringen).

To be clear: (almost) no one is forced to pay church tax in Germany - only members of the churches that have an agreement with the government to collect it on top of income tax have to pay it, and you can choose to leave those churches. For Protestants ("evangelisch"), that's usually not as big of a deal as it is for Catholics who still believe; there are plenty of non-church-tax-collecting Protestant churches around the country, including the one I'm a member of.

"Almost": there were many couples with very unequal incomes in which the non/lower-earner would stay in the church so that the family would still get the various services (baptisms, weddings, preferential admission to church-affiliated schools, etc) while the higher earner would "leave" (on paper), leaving the family paying far less in church tax. That loophole was closed - if the higher earner isn't a member of another church collecting church tax, they can be required to pay church tax to their spouse's church. I'm not sure this is still in effect, but it was for a while.
