Switzerland does seem to be the place to be right now for bitcoin and blockchain related happenings, you can even purchase bitcoin at their train stations https://www.sbb.ch/en/station-services/services/further-services/bitcoin.html
Paying your tax in bitcoin would certainly bring in some revenue to the taxman that probably would be avoided, I look forward to seeing how the rest of the world looks at bitcoin and tax.
Unless you are dealing with a large amount then I don't think you really have too much too worry about at the moment anyway.
