Be careful about generalization though. In Switzerland the "ecclesiastic tax" is not a federal matter but a cantonal one and in some cantons even a communal one. In some cantons it is mandatory, in others it isn't and a mere request addressed to the proper authority can be enough for you not to pay it. For example in Valais while most people pay it, you are not obligated to do so.
