Just want to chime in amd say that this is absolutely true. Tons of other nations don't require anything like this. I can do my taxes by simply logging in on a government website, read the report they've got, and if I see nothing wrong, be done with everything by clicking "send". Takes a whole 2 minutes for most salaries people.

97% of the time, all my deductibles are already there and correct to the last cent.
