What this value means
Applies to residents' annual comprehensive income (employment, business, pension, other; financial income above the KRW 20m threshold is aggregated). Rates shown are national income tax only — personal local income tax (개인지방소득세) of 10% of the PIT liability applies on top, giving effective marginal rates of 6.6%-49.5%. NTS progressive quick-deduction amounts: 1.26m/5.76m/15.44m/19.94m/25.94m/35.94m/65.94m KRW for brackets 2-8. The two lowest thresholds were last raised (12m→14m, 46m→50m) by Act No. 19196 effective 2023; the December 2025 tax reform changed dividend-income separate taxation but left the Article 55(1) schedule intact for 2026 (EY Global Tax Alert 'Korea enacts 2026 tax reform bill', 2026-01-26, cross-check; NTS table loaded 2026-07-20 shows the 2023-onwards schedule as current). law.go.kr article deep links (e.g. /법령/소득세법/제55조) return JS title-shells to plain fetchers — schedule verified via the NTS page and statute mirrors.
