A Complete Guide to the 4 Major Social Insurance Systems for Foreign Instructors in Korea

If you’re teaching in Korea, social insurance isn’t just another payroll line—it’s your safety net. Here’s a clear guide to the four major social insurance programs, how to check your enrollment online, and what to know about a National Pension lump-sum refund when you leave.

1. Why Should Foreign Instructors Care About Social Insurance?

Foreigners aged 18 to 60 residing and working in Korea are legally required to enroll in the four major social insurance programs: National Pension, National Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance.

Yes, these programs mean monthly salary deductions—but they protect you against health issues, workplace injuries, unemployment, and retirement. Understanding them early helps you avoid surprises on payday and stay compliant with Korean law.

2. Key Highlights of the 4 Major Social Insurance Systems

• National Pension: Designed to provide financial stability for retirement, disability, or death. Employees typically contribute 9% of monthly income, split equally between the employee (4.5%) and the employer (4.5%).
• National Health Insurance: Mandatory for foreigners who have resided in Korea for 6 months or longer. It covers medical treatments and health checkups. Workplace-based subscribers can often register family members (such as spouses or children) as dependents to share benefits.
• Employment Insurance: Provides unemployment benefits and vocational training support.
• Industrial Accident Compensation Insurance: Covers medical expenses and benefits for work-related injuries, illnesses, or commuting accidents. This is funded entirely by the employer.

3. How to Easily Check Your Enrollment Online

If you need a certificate of coverage for your workplace or personal records, use the National Social Insurance Information Link Center at www.4insure.or.kr.

• How to log in: Select the “Individual (Non-member) Login” menu. Verify your identity using your Alien Registration Number (ARN) and a digital certificate (such as Kakao, Naver, or PASS) or a financial certificate.
• Issuing certificates: Once logged in, you can instantly download or print your “Certificate of Social Insurance Subscription/Qualification” in Korean or English.

4. Pre-Departure Check: National Pension “Lump-sum Refund”

When you permanently leave Korea to return home, you may be eligible for a lump-sum refund of the pension contributions you have paid.

5. Useful Contact Information for Administrative Support
