I think it's 1% of your income or something like that which is collected by the state for the church. (That itself is often discussed in Germany, as state and church should obviously not be mixed...)
But you can "leave" the church, it costs something like 40 Euro for the administrative action and that's it. No discussion whatsoever and you can keep your money. :-D
Well, right now it is. The original registry OP is referring to was probably not started to identify and exterminate people who were Jewish, but started for some more innocent reason and then abused when the wrong party assumed power.
I'm not totally into this right now but I think there were no such registrations in the beginning.
But as the Nazis had more and more influence laws ("Nürnberger Gesetze") were passed which required Jewish people to mark their shops and register themselves as Jewish etc. pp.
Also denunciations and more from neighbors happened, after Jews were declared "enemies" of the state, so everything came together.
edit: But potential misuse of any kind of registers by whomever is obviously the strongest point against those registers after all. Right-wing parties are always eager to have such things for obvious reasons.
