When these numbers change
South Korea's tax year runs with the calendar year and begins on January 1. Rates, thresholds and contribution ceilings are usually revised at that point, so the same gross salary can produce a different take-home figure from one tax year to the next — which is why this page states the tax year it is calculating for rather than leaving it implied.
The annual filing deadline is May 31. Most employees settle tax through their employer's year-end settlement in February and never file in May. This date applies only if you are required to file your own return.
