And they have VAT too. Everybody has to have VAT in EU. Or else EU gets really angry.

It's not like they have VAT because they are in the EU. They had VAT since 1962, and they have had it at the current rate of 25% (higher than most EU countries) since 1992, which is way before the EU VAT directive was even a thing.

Edit: Correction, the EU VAT directive actually has its origins before 1992, but still after Denmark already had its own VAT.

My point was that you can safely assume that any EU country has at least 15% VAT.

For non-essential goods. There are two VAT brackets, the low tariff is 5% minimum.

In fact there are several levels - municipal, state and church tax, bottom, middle and top tax. VAT, as well as other industry taxes, among other a tax on the air in softice and an special nut-tax.

Most of those do not interfere with the lives of the average Danish citizen. Church tax is interesting though, and highly debated. Everyone's leaving the churches, especially in Copenhagen. Many teenagers deregisters from the Church of Denmark[0] to save money; the usual counterargument is mostly based on history; i.e. we should support the churches for the buildings'(not the institution) historic value.

The church tax is not the only income for the church. It receives a large amount of money from the general tax, exactly to perform restorations of old buildings and cultural heritage. Even if you deregister from the church and therefore do not pay direct church tax, some of your tax kroner will go to the church anyway.
