How your tax is calculated

After a ₩1.5m basic deduction, income tax rises from 6% on the first ₩14m of taxable income through 15%, 24%, 35%, 38% and 40% to 45% at the very top. The four major insurances (pension, health, employment, industrial accident) take about 9%. Local income tax of about 10% of the tax bill is added and is not included. Your marginal rate is 15% — every additional ₩1 you earn keeps roughly ₩0.85 after tax and 4 insurances.

What if…

₩25,000,000 instead? Your take-home rises by roughly ₩61/month — see ₩25,000,000 after tax.
With a 5% pension contribution, your monthly take-home would be ₩1,296,292 but you'd save around ₩150,000 in income tax over the year.
10 hours of overtime a month at time-and-a-half would add about ₩127,500 to your monthly take-home.
