> Your employer pays the tax on your behalf directly from your salary and updates the tax office as to how much you make. In turn, the tax office tells your employer how much tax to pay from your salary, without any input required from yourself.
Same thing happens in the US. When most people file their taxes here, they get money back because they already overpaid.
For example I spent a few thousand trying to launch a business this year, and that is all tax deductible. So I'll file that with my tax form that my employer sends me (with the salary info prefilled), and I'll end up getting some money back because my taxable income is lower than what the gov't expected.
