Understanding Korean Salary Deductions (2026 Guide)
When you work in South Korea, your monthly take-home pay (실수령액) is determined by subtracting four major social insurances and income taxes from your gross salary. For 2026, the Korean government has updated several contribution rates to reflect the aging population and social welfare needs.
The 4 Main Social Insurances (4대 보험)
National Pension (국민연금)
Rate: 9% of monthly gross (4.5% employee, 4.5% employer). For 2026, the maximum monthly contribution is capped at a gross salary of ₩6,170,000.
Health Insurance (건강보험)
Rate: ~7.09% total. The employee portion is 3.545%. This provides near-universal coverage for medical visits and prescriptions in Korea.
Employment Insurance (고용보험)
Rate: 0.9% for the employee. This fund supports unemployment benefits (Sill-eop-geu-yeo) and job training programs for laid-off workers.
Long-term Care (장기요양보험)
Rate: 12.81% of your *Health Insurance* amount. This pays for elderly care services and nursing homes.
Income Tax & Local Resident Tax
In addition to insurance, you pay Earned Income Tax (소득세) which follows a progressive scale (6% to 45%). On top of the national tax, a Local Resident Tax (지방소득세) equal to 10% of your national tax is also deducted automatically.
💡 Insider Tip: The 19% Flat Rate
Foreigners working in Korea can opt for a 19% flat tax rate on their gross income if their annual salary is high (typically over ₩120M). Use our Income Tax Optimizer to see if you qualify for this savings.
Frequently Asked Questions (FAQ)
Can I get my National Pension back when I leave?
# Yes, eligible expats receive a lump-sum refund upon departure.
Citizens of many countries (including the US, Canada, Australia) are eligible for a Lump-sum Refund when they permanently leave Korea. You must apply at the National Pension Office before your departure.
Are bonuses (상여금) taxed differently?
# No, bonuses are treated as standard earned income for tax purposes.
Bonuses are treated as earned income and are added to your annual gross for tax purposes. However, they are usually not subject to the same monthly insurance withholding logic as your base salary.
What is the "Year-End Settlement" (연말정산)?
# It is the annual tax recalculation and refund process every February.
Every February, Korean employees submit receipts for medical, education, and credit card spending. The government then recalculates your total annual tax and often issues a "13th month" refund check if you overpaid during the year.
Do I pay insurance if I am a Freelancer (3.3%)?
# No, but you must pay premiums as a local subscriber yourself.
Freelancers typically only have 3.3% tax withheld. However, you are responsible for paying your own National Health Insurance and Pension as a "local subscriber," which can sometimes be more expensive than employer-sponsored plans.
