Minor correction, depends on the eu countries, but in France, the authors tax charged on copy mediums is in addition to the product price without VAT, and then VAT is applied to the whole. So you pay VAT on the authors tax. To be clear you pay tax on tax, a french speciality.

In NL you pay VAT on the special taxes added to fuel and there are a couple of other cases like this. Tax on tax is unfortunately not just a French thing.
