Professional verification
The South Korea calculator has not yet been reviewed by an independent tax professional. Until it is, results rely on the official sources, worked examples and automated checks below. How our verification works.
Worked examples, recalculated live
Each example was worked by hand from the official rules before publication. The live calculator must reproduce it exactly, to the cent, or the rule set cannot be published.

Rule version
Version KR-2026-v1, approved on 2026-10-20, last validated on 2026-10-20. Rules are effective from 2026-01-01 to 2026-12-31. Published rule versions cannot be edited; corrections are released as a new version.
Calculation assumptions
- An eligible foreign employee elects separate taxation at 19%, so exemptions, deductions and tax credits do not apply.
- Local income tax is 10% of national income tax, represented as 1.9% of gross employment income.
- The standard 2026 workplace-insurance employee rates apply; pension uses the KRW 6.37 million monthly ceiling to June and KRW 6.59 million from July 2026.
