Im Denmark that pretty much how it works. If you have complex scenarios you might need to adjust the numbers a bit, for example if you have stocks abroad or income from gigs. Many trading platforms in Denmark do automated reporting, and some gig-economy apps do automated reporting too. But if you setup a lemonade stand, well, reporting is in you :) The tax authorities also have pretty good phone support. It's a bit overloaded around filing season (but getting through is possible), but if come home from an internship abroad and call them, they are happy to tell you where and how to report income and taxes paid in Canada for example. I bet it's expensive to offer phone support. But if you want people to pay taxes the best way to do it is to make it easy to do the right thing. This advice goes pretty much everywhere, if you make it easy to do something, people will do it :)
