Currently I'm living in a country inside the Schengen area (Hungary, to be more specific), but I'm planning to move to Norway (also in Schengen, info may be related to work permit). However I'd prefer to find a remote job as a software developer that can be done from anywhere. I plan to operate as an entrepreneur registered in Norway so I would pay all my taxes there, but I would actually work from any possible area of the world. What do I need to report at Norwegian authorities and how will I be able to fulfill my taxing obligations?
