germany also has the ‘church tax’ issue. one checks off a box when filing one’s taxes in Germany and they subtract more for your church. It can be as little as a couple hundred or as much as a couple thousand.
many young people do not want the extra subraction, so they get kicked out of their church.
I’ve read about that; an interesting concept. Sounds like you pay a tithe if you’re registered to a specific denomination. Not sure what the penalty is for not paying; refusal of sacraments?
