Is Austria one of those countries that collect some kind of a tax from those who are “registered” as belonging to a particular religion?
When I was 20 years old I had a summer job in Austria and I was asked my religion--because I was under 21 I didn't have to pay the tax. There were a couple of guys from England working at the same place and they rejected being classified as "Evangelisch" because they were Church of England, not Lutheran.
