In Germany it's not really true. AFAIK you pay those taxes only if you are registered follower of 3 main religions. You literally can opt out, they are a counter example.

Poland is the one I experience it. Church is funded in multiple ways. At least 3 billion PLN a year from concordat deal from 90's. Priests have pensions and annuities. Churches pay no taxes on (heating) fuels. Schools pay for Religious Education classes, very often run by priests or nuns. Uniformed services almost always pay for cleric's services or clerics fully in their services.

Of course church still gathers funds on their own, sometimes using dark patterns.

I think tax breaks are different from direct funding, the same for payment for specific services at a reasonable price. For example the UK exempts virtually all religious bodies from tax, and its on the same basis as a huge range of things (e.g. amateur sports, equality and diversity, community facilities...). I would not consider that state mandated payment for services.

I do not know enough about the concordat or how Polish pensions work to comment on those. I would be interested but there does not seem to be a lot of information online (e.g. the wikipedia article is a stub)
