In the Netherlands the tagline of the tax authorities used to be "we can't make it funnier, but we can make it easier". Most tax forms are online and pre-filled with data they already have. For most people it's probably a matter of minutes.
I also enjoy filing taxes. It’s one of those things that allow you to reflect on your work, how you did, optimize the deductions, and get a reward at the end. It’s fun.

For most people, it's a case of quickly doublechecking all your income/property numbers and then spending some time on items you might be able to deduct.
All you want would still be possible under a system where the govt pre-fills forms. It’s just the 99.9% of Americans who DON’T find it to be fun would get a leg up.
