Pretty much yeah. I guess there are some deductions which need to be filed manually as the government would have no way of knowing about them. Like if you have a really long commute to work you get to deduct a certain amount per KM from your taxes.

But mostly these days, unless you run a company, you don't really have to change much about your pre-filled tax statement. Only once have I experienced that my housing association made addendums to the yearly tax report that needed to be changed in my tax statement.

I also lost some money on micro loans last year that apparently I had to file deductions for myself, but it amounted to so little money that I just let the state keep that money.
