In Germany the official application to submit your taxes as a private person to the state has been a windows application for years. Using the app was a 1:1 copy of the official paper forms. Disregarding the complexity of the german tax law, you had a reference to the papers. So it was kind of easy to use the digital counterpart one was accustomed to.

It was disimproved by hauling it into a web app, which breaks with all the usual connections you built with the paper equivalent and is the most UX unfriendly monstrosity one could create. From this year on you HAVE TO USE IT. I deeply disrespect this regression, which forces many people into paying a tax office for their private tax submission.

I wish for a swedish/norwegian system, where the state courts you for YOUR money. I don't know a single person in Germany which states: "I love doing my tax submissions!"
