Korea's Four Social Insurances: A Complete Guide to National Pension, Health, Employment & Industrial Accident Insurance
What Are Korea’s Four Social Insurances?
Korea’s four social insurances (4대보험) form the backbone of the country’s social safety net. Enrollment is mandatory for all employees and employers. The four programs are: National Pension, National Health Insurance, Employment Insurance, and Industrial Accident (Workers’ Compensation) Insurance.
The system works by collecting a fixed percentage of income as premiums and spreading life’s major financial risks — illness, unemployment, retirement, and workplace injury — across society as a whole.
Note for international readers: The contribution rates and rules below are specific to South Korea. Your country’s social insurance system will differ, but the underlying concepts — shared risk, income-based contributions, employer co-payments — are broadly similar worldwide.
1. 2024 Contribution Rates at a Glance
2. Each Insurance in Detail
National Pension
| Item | Details |
|---|---|
| Rate | 9% (Employee 4.5% + Employer 4.5%) |
| Reference Income Floor | ₩370,000/month |
| Reference Income Ceiling | ₩5,900,000/month (2024) |
| Minimum Premium (Employee) | ₩33,300 |
| Maximum Premium (Employee) | ₩265,500 |
| Administering Body | National Pension Service (NPS) |
Even if your monthly income exceeds ₩5,900,000, premiums are calculated only up to ₩5,900,000. This means high earners pay a lower effective contribution rate — the system has a built-in ceiling.
National Health Insurance
| Item | Details |
|---|---|
| Rate | 7.09% (Employee 3.545% + Employer 3.545%) |
| Long-term Care Insurance | Health Insurance Premium × 12.95% (billed separately) |
| Enrollment Floor | Monthly salary of ₩280,000 or more |
| Dependent Registration | Family members of workplace subscribers receive medical coverage |
| Administering Body | National Health Insurance Service (NHIS) |
Combined Health + Long-term Care Example (Monthly Salary ₩3,000,000):
- Health Insurance: ₩3,000,000 × 3.545% = ₩106,350
- Long-term Care: ₩106,350 × 12.95% = ₩13,773
- Total Employee Cost: ₩120,123
Employment Insurance
| Item | Details |
|---|---|
| Unemployment Benefit (Employee) | 0.9% |
| Unemployment Benefit (Employer) | 0.9% |
| Employment Stability Levy (Employer) | 0.25–0.85% additional (varies by company size) |
| Benefit Eligibility | Involuntary separation + 180+ days of premium payments |
| Benefit Duration | 120–270 days (based on tenure and age) |
| Benefit Amount | 60% of pre-separation average wage (subject to upper and lower limits) |
Daily benefit = Average daily wage in the 3 months before separation × 60%
2024 caps: Upper limit ₩66,000/day; Lower limit: 80% of minimum wage × 8 hours
Industrial Accident Insurance
| Item | Details |
|---|---|
| Who Pays | Employer pays 100% |

4. Workplace Subscriber vs. Regional Subscriber
| 구분 | ||
|---|---|---|
| Premium based on monthly salary — employer covers 50% | Premium based on combined score of income, property, and vehicles — subscriber pays 100% | |
| National Pension: reference monthly income × 9% (employer pays half) | National Pension: reported income × 9% — subscriber pays full amount | |
| Employment Insurance: automatic enrollment (wage employees) | Employment Insurance: self-employed may enroll voluntarily (benefits require business closure) | |
| Industrial Accident: employer enrolls (no cost to employee) | Industrial Accident: sole proprietors may voluntarily enroll |
Freelancers and sole proprietors bear 100% of their health insurance premium, and property and vehicle ownership are also factored in — not just income. When leaving a company job and switching to regional subscriber status, premiums can spike sharply. Consider using the voluntary continuation enrollment option to keep your workplace subscriber rate for up to 36 months.
5. Enrollment Exemptions
| Worker Type | Exemption Details |
|---|---|
| Part-time workers (under 60 hrs/month) | May be excluded from National Pension and Health Insurance (unless continuously employed for 3+ months) |
| Day laborers | Industrial Accident Insurance applies immediately; National Pension and Health Insurance are conditional |
| Workers 65 and older | Excluded from Employment Insurance unemployment benefits |
| Foreign workers | Partial exemptions depending on visa type |
