Finland: "Oh hey so your employer already handed us an estimated portion of your income for taxation using a percentage based on your income from last year. Now that the year is over and we could calculate your final tax rate for this year, here's your tax return back, with interest.
Just let us know if we missed anything, like a deductible or something."
i don’t really know too many people that have to claim deductions unless they’re running a business, and business tax is of course different because you have to pay all your employees tax etc (which is what makes it so simple for employees)
it really is just next next next done and you receive a deposit into your nominated bank account
