Here in Sweden I receive my tax form pre-filled in a digital mailbox (basically a PDF of the tax form I'd get through snail mail on a website), I can see on the first page the total amount of tax paid, how much I owe or will receive as tax return and then another section with more details about interest I've paid, how much of that was deducted from my taxes, etc.

In about 5 minutes I have an overview of all the taxes paid from my income, how much went to the national, kommun/local government and I'm done.

I don't follow what is the argument about how making this process simple is considered anti-democratic.
