KRW 150,000 salary in South Korea

How South Korea income tax works

The calculator applies the published tax bands to income after the supported deductions. Each band applies only to the portion inside it. These bands use the taxable income base.

Additional schedules: Local income tax. These are calculated separately and included in the tax total. Component-specific credits are applied only to their own tax schedule.

The displayed tax total covers Employment income tax. See the country assumptions for details.

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.
