South Korea Net Salary Calculator 2026

How is net salary calculated in South Korea?

In South Korea, net salary is calculated by subtracting social security contributions (NPS pension + health + employment insurance) and income tax (Income tax + local income tax (10%)) from the annual gross salary.

Income tax + local income tax (10%) uses a progressive scale. Rates range from 6,6 % for the lowest incomes to 46,2 % for the highest. Only the portion of income that falls within each bracket is taxed at that rate, never the full salary.

NPS pension + health + employment insurance contributions amount to approximately 9,05 % of gross salary, funding the pension, healthcare and other social benefits available to employees in South Korea.

This calculator uses official data from National Tax Service Korea (nts.go.kr) for 2026. Results are indicative; for exact calculations or specific situations (personal deductions, special regimes) consult a tax adviser or the country's tax authority.

Contributions: NPS pension 4.5%, health insurance 3.545%, long-term care (~0.16%) and employment 0.9% (total ~9.2%). Tax rate includes local income tax (10% surcharge on national tax). Allowance is approximate; actual deductions vary.
