Well Amazon actually has low profits so they barly pay taxes, because they use all their money in expanding their business. This is actually something which you can do as a german in germany anyways.

And since ~2016 or earlier? amazon pays taxes in every country they operate. In germany they even changed the invoice address to be german ~2016-2017. a long time they used luxemburg as their invoice address which was really clever, until it broke out a scandal. http://europa.eu/rapid/press-release_IP-17-3701_en.htm It contains a good picture, which explained it. And now all sales are recorded in the operating countries. and amazon now needs to provide certain tax related information on a per country basis.
