Re: A solution?
I cant find the exact proportion here in Sweden, but it might very well be about 90%. Including various home owners. The process this year for me (owns a condo apartment, so not totally simple).
1. Tax office send me a copy of their pre-filled simple form to my secure digital mailbox
2. I look at it: can't think of anything to add or adjust: amending the form is dead simple in most cases. If I was a financially complex person (owning a business, etc) I might need to do the full form instead.
3. A week or so later I can digitally file my taxes, accepting all their calculations: salaries, interest, etc are all reported to them, so they know better than I what the numbers are. This takes about 1-2 minutes, and I naturally get a digital receipt.
4. A few week later I get the money they owe me* directly into my bank account
* I have my employer deduct a bit more then the tables suggest, such that something exceptional would have to happen for me to need to pay extra tax. Keeps my life simple, and I can afford to push a little bit of salary in front of me.
