Progressive income tax
Korean income tax is tax base × rate − progressive deduction. The base is your total income minus deductions.
The 2026 brackets run 6% to 45% across eight steps (6% up to 14M KRW, then 15%, 24%, 35%, 38%, 40%, 42%, and 45% above 1B). Actual tax also subtracts credits and adds penalties; a 10% local income tax applies on top. See the VAT calculator or salary calculator.
