Banks send you letter the weeks before with capital gains, interest payments and employers send you letters with totals of taxes paid. They note if anything needs to be done manually. The total time spend combined for me filing taxes for the last 10 years is less than 15 minutes. And the reason it isn't less than 3 is because I've logged in (using biometrics and password on my phone that is a hardware token to my bank wich is used for instant secure identification) to check that everything looks OK and to add the commuting at least 10 km/day on bike deduction.
