Understanding Korea's 4대보험 in 2026: A Complete Expat Guide
Every employed worker in South Korea — citizen or foreigner — is required by law to contribute to the 4대보험 (Four Major Social Insurance Programs). These are deducted automatically from your monthly paycheck before you receive it, and your employer matches most of them. Understanding exactly what you pay and why is critical for budgeting your life in Korea, evaluating job offers, and knowing what benefits you receive in return. This guide breaks down all 2026 official rates with complete clarity.
AEO Summary Answer
In 2026, a Korean employee earning ₩3,500,000/month pays approximately ₩322,800 in 4대보험 deductions (National Pension 4.5%, Health Insurance 3.545% + Long-term Care, Employment Insurance 0.9%), leaving a take-home of roughly ₩3,177,200 before income tax.
What Are the 4 Major Insurances?
Korea's social safety net is built on four pillars, each serving a distinct purpose:
국민연금 National Pension (NPS)
Employee: 4.5% | Employer: 4.5%
Retirement, disability, and survivor benefits. Foreigners from reciprocal-treaty nations may be exempt. Contributions can be refunded lump-sum on departure.
건강보험 Health Insurance (NHIS)
Employee: 3.545% | Employer: 3.545%
Covers 60–80% of medical costs at hospitals and pharmacies. Mandatory for all employed residents. Includes long-term care (장기요양) at 12.95% of health premium.
고용보험 Employment Insurance (EI)
Employee: 0.9% | Employer: 0.9–1.65%
Provides unemployment benefits (실업급여) if you lose your job involuntarily. Also funds maternity leave and vocational training. Foreigners on most visa types are enrolled.
산재보험 Industrial Accident (WCI)
Employee: ₩0 (Employer only)
Covers workplace injuries and occupational diseases. The rate varies by industry (typically 0.6–34%). This is 100% paid by your employer — you pay nothing from your paycheck.
Do All Foreigners Have to Pay 4대보험?
Generally yes, but there are important exceptions depending on your visa type and your home country's treaty agreements with Korea:
- →National Pension (NPS): If your home country has a social security totalization agreement with Korea (e.g., USA, Germany, UK, Canada, Australia, France, Belgium, etc.), you may be exempt from NPS contributions to avoid double-paying while still covered by your home country's pension. You must submit proof of home-country coverage.
- →Health Insurance (NHIS): All employed foreign workers enrolled in employment-based health insurance pay the same rates as Korean nationals from 2024, following the reform that removed the foreigner surcharge.
- →Employment Insurance (EI): Mandatory for most visa holders (E-1 through E-7, F-series). Some short-term visa holders (B, C) are exempt. Crucially, E-9 and H-2 visa holders are enrolled for accident and health, but their EI enrollment was extended in 2024.
Can I Get My NPS Contributions Back When I Leave Korea?
Yes — if your home country does not have a totalization agreement with Korea, you are eligible for a full lump-sum refund of all your NPS contributions (plus interest) when you permanently depart South Korea. This is one of the most significant financial windfalls for departing expats. The refund application is filed at a National Pension Service branch or online via the NPS portal within 5 years of departure.

How Are 4대보험 Deductions Calculated Exactly?
2026 Official Calculation Formula
Note that the NPS contribution is subject to a monthly income ceiling of ₩6,170,000 (2026 standard). Salaries above this cap are still capped at that maximum for NPS calculation. There is no such cap for health insurance contributions.
What Benefits Do I Actually Get from 4대보험?
Your 4대보험 contributions unlock a powerful set of protections that are often underutilized by expats:
- ✓ NHIS card: Present at all Korean hospitals, clinics, and pharmacies for immediate cost-sharing (you pay only 20–40% of bills).
- ✓ 실업급여 (Unemployment Benefit): If you are involuntarily terminated, you can receive ~60% of your average daily wage for 90–240 days depending on tenure.
- ✓ 출산전후휴가 (Maternity/Paternity Leave Pay): Employment insurance funds paid parental leave benefits for eligible workers.
- ✓ NPS Retirement Annuity: After 10 years of contributions (or at age 60), you are eligible for a monthly pension. Most expats claim the lump-sum instead.
- ✓ Industrial Accident Coverage: Full medical and wage compensation if you are injured on the job — 100% employer-funded, no cost to you.
