- Industrial Accident Compensation Insurance (산재보험): Mandatory for ALL workers regardless of visa or nationality — even on the first day of work. If unregistered, the employer must cover 50% of medical costs retroactively.
- National Health Insurance (건강보험): Must be reported within 14 days of hiring. Late or missed reporting incurs a fine of up to 5,000,000 KRW.
- National Pension (국민연금): Reciprocity principle — workers from treaty countries (USA, Japan, etc.) are obligatorily enrolled; non-treaty countries may be voluntary or exempt.
- Employment Insurance (고용보험): Voluntary enrollment for most visa types. F-2, F-5, F-6 visa holders are mandatorily enrolled.
- See the comparison table below for E-9, E-7, and H-2 visa differences.
If you hire even one foreign employee, the 4 major social insurance rules differ from those for Korean nationals. Each insurance has different mandatory/voluntary rules, and National Pension enrollment depends on whether the worker's home country has a Social Security Agreement (SSA) with Korea. Missing a reporting deadline by even one day can result in fines of several million won. If an accident occurs without Workers' Compensation enrollment, the employer bears the full cost of treatment. This guide provides essential practical information on all four insurances for both corporate HR managers and foreign workers themselves.
As of 2026, the National Pension contribution rate is 9.5% and the Health Insurance premium rate is 7.19%, both increased from the previous year. This is an important time to review both the cost changes and reporting procedures carefully.
① Industrial Accident Compensation Insurance — Covers Everyone from Day One, No Exceptions
Industrial Accident Compensation Insurance (산업재해보상보험, commonly called 산재보험) is the only insurance among the four that applies mandatorily to all workers regardless of visa type, residence status, or nationality. Whether undocumented, on a short-term contract, or working a single day as a day laborer — coverage begins from the first day of work. There are no exceptions to this rule.
Premiums are paid entirely by the employer — nothing is deducted from the worker's wages. HR managers must register the workplace with the Korea Workers' Compensation and Welfare Service (근로복지공단) within 14 days of the establishment date (the first day any worker is hired). Failure to register results in retroactive premium charges plus a fine of up to 3,000,000 KRW.
- The Korea Workers' Compensation and Welfare Service will recover 50% of benefits paid to the injured worker from the employer
- Retroactive premiums for the unregistered period plus late payment charges will be added
- Total costs — including medical, suspension-of-work, and disability benefits — can reach tens of millions of won
- Foreign workers are protected equally, and employers cannot be exempted from liability
This applies equally to all foreign workers holding E-9 (Employment Permit), E-7 (Designated Activities), H-2 (Working Visit), F-2, F-5, and F-6 visas. Part-time and daily foreign workers are not exempt. The most important practical point: Workers' Compensation Insurance coverage begins automatically the moment you hire someone — both employers and HR staff must be fully aware of this.
② National Health Insurance — Report Within 14 Days of Hiring or Face Up to 5,000,000 KRW Fine
National Health Insurance (국민건강보험) is mandatory for foreign workers as well. Any foreigner employed at a workplace must enroll as a workplace subscriber regardless of nationality. The employer must notify the National Health Insurance Service (NHIS / 국민건강보험공단) of the worker's enrollment within 14 days of the hiring date.
The 14-day deadline is strictly enforced. Missing or late reporting results in a fine of up to 5,000,000 KRW. The most convenient way to report is through the NHIS Cyber Civil Service Center (www.nhis.or.kr), EDI (Electronic Data Interchange), or the 4 Major Social Insurance Information Linkage Center (www.4insure.or.kr) for integrated reporting.
- Reporting deadline: within 14 calendar days of the hiring date
- 2026 premium rate: 7.19% of monthly salary (employer and employee each pay 3.595%)
- Long-term care insurance: an additional 0.9182% of the health insurance premium (2026)
- Loss of eligibility upon resignation or visa expiration must also be reported within 14 days
- Reporting portal: www.4insure.or.kr (integrated reporting for all 4 insurances)
A foreign worker cannot refuse to enroll in Korean Health Insurance simply because they are already enrolled in their home country's health plan. However, some residence statuses (short-term D-category visas, etc.) may qualify for exemption — check with NHIS in advance. If a foreign worker's alien registration period expires while still employed, they may retain health insurance eligibility, so HR managers should track individual cases carefully.
③ National Pension — Reciprocity Principle: Treaty Countries Mandatory vs. Non-Treaty Countries Voluntary
The National Pension (국민연금) is the insurance whose application varies most significantly depending on the worker's home country. The core principle is reciprocity (상호주의): if Korean citizens must enroll in a foreign pension system while working in that country, then that country's nationals must enroll in Korea's National Pension — and vice versa for exemptions.
As of 2026, Korea has Social Security Agreements with 42 countries. Agreements fall into two main types: Totalization Agreements (combining contribution periods from both countries) and Premium Exemption Agreements (temporary exemption when proof of home-country enrollment is submitted). In 2024, agreements with Vietnam and the Philippines entered into force.
| Category | Representative Countries | National Pension | Notes |
|---|---|---|---|
| Totalization Agreement | USA, Canada, Germany, France, Australia, UK, Vietnam, Philippines | Mandatory Enrollment | Contribution periods from both countries can be combined |
| Premium Exemption Agreement | Japan, Italy, Switzerland | Temporary exemption during dispatch period | Requires proof of home-country enrollment |
| Non-Treaty Countries | China, Indonesia, Cambodia, Myanmar, Nepal | Reciprocity applied (effectively voluntary or exempt) |
— |
- 2026 National Pension rate: 9.5% (employer 4.75% + employee 4.75%) — increased from 9% in the previous year
- Even treaty-country nationals can apply for a temporary exemption by submitting proof of home-country pension enrollment
- E-9 visa workers — enrollment obligations differ by nationality. Confirm nationality before hiring.
- Vietnam and Philippines agreements entered into force in 2024 — detailed implementation still being refined; confirm with the National Pension Service (NPS)
- Lump-sum refund upon departure is available — conditions vary depending on treaty status
E-9 visa workers come from diverse countries including Vietnam, the Philippines, Cambodia, Indonesia, and Thailand. Before hiring, it is strongly recommended to verify the latest nationality-specific enrollment requirements with the National Pension Service (NPS, ☎ 1355) or the Korea Workers' Compensation and Welfare Service.
④ Employment Insurance — Three Tiers by Visa: Mandatory, Voluntary, or Excluded
Employment Insurance (고용보험) is the most complex of the four insurances when it comes to foreign workers. While virtually all Korean nationals are mandatorily enrolled, foreign workers are classified into three tiers based on their visa type: mandatory enrollment, voluntary enrollment, or complete exclusion.
| Visa Type | Employment Insurance | Notes |
|---|---|---|
| F-2 (Residence), F-5 (Permanent Resident), F-6 (Marriage Migrant) | Mandatory Enrollment | Same as Korean nationals |
| E-1~E-10, H-2 (Working Visit), F-4 (Overseas Korean) | Voluntary Enrollment | Only if the worker opts in |
| D-7, D-8, D-9 (Corporate Transfer, Investment, Trade) | Reciprocity | Depends on whether Korean nationals are covered in the home country |
| D-1~D-6, D-10 (Language Study, Academic, Job Seeking) | Excluded | Generally cannot enroll |
E-9 (Employment Permit) visa workers are subject to voluntary enrollment. Employers cannot force enrollment — the worker must opt in themselves. The same applies to H-2 (Working Visit) workers. It is important to clearly inform foreign workers at the time of hiring that those not enrolled in Employment Insurance are not eligible for unemployment benefits if they lose their job.
- Unemployment benefit premium: 1.8% of wages (employer 0.9% + employee 0.9%)
- Employment stability and vocational training: paid by employer only, 0.25%–0.85% depending on company size
- When a voluntarily-enrolled foreign worker applies — a separate worker consent form and enrollment application must be submitted
4 Major Insurance Comparison by Visa — E-9, E-7, H-2 at a Glance
E-9, E-7, and H-2 are the most common visas when companies hire foreign workers. Since National Pension enrollment depends on the worker's nationality and SSA status, the table below reflects the default principles.
| Insurance Type | E-9 (Employment Permit) | E-7 (Designated Activities) | H-2 (Working Visit) | F-2·F-5·F-6 |
|---|---|---|---|---|
| Workers' Comp. Insurance | ✅ Mandatory | ✅ Mandatory | ✅ Mandatory | ✅ Mandatory |
| Health Insurance | ✅ Mandatory | ✅ Mandatory | ✅ Mandatory | ✅ Mandatory |
| National Pension | 🔶 Varies by nationality (reciprocity) | 🔶 Varies by nationality (reciprocity) | 🔶 Varies by nationality (reciprocity) | ✅ Mandatory (ages 18–60) |
| Employment Insurance | 🔷 Voluntary | 🔷 Voluntary | 🔷 Voluntary | ✅ Mandatory |
The E-7 (Designated Activities) visa is issued to professional and skilled foreign workers. National Pension and Employment Insurance treatment can vary by nationality and contract terms. For companies in IT, engineering, or healthcare that frequently hire E-7 workers, it is recommended to build an individual pre-hire verification step with the National Pension Service into your standard HR process.

Frequently Asked Questions (FAQ)
The Korea-Vietnam Social Security Agreement entered into force in 2024, so in principle Vietnamese nationals are subject to mandatory National Pension enrollment. However, as some details of the agreement are still being finalized, please confirm the latest requirements with the National Pension Service (☎ 1355) before hiring.
Daily workers employed for 1 month or longer must be enrolled as workplace subscribers. Workers employed for less than 1 month require individual verification. Workers' Compensation Insurance applies from even a single day of work.
A foreign national who no longer has a Korean address (after departure) can apply for a lump-sum refund of National Pension contributions. Conditions may differ for nationals of SSA countries. The refund can be claimed after departure through the National Pension Service, or through the employer during employment.
That is correct. Foreign workers eligible for voluntary enrollment who have not enrolled in Employment Insurance are not entitled to unemployment benefits. When hiring E-9 or H-2 workers, clearly explain their Employment Insurance enrollment options and register them promptly if they wish to enroll — this helps prevent disputes.
Yes. The 4 Major Social Insurance Information Linkage Center (www.4insure.or.kr) allows you to file Workers' Compensation, Employment, Health, and National Pension reports all at once. Processing the initial workplace establishment report and employee enrollment notifications together on this site greatly improves HR efficiency.
For foreign worker insurance reporting, follow this systematic order: Workers' Comp. (all mandatory) → Health (14-day mandatory) → Pension (verify by nationality) → Employment (verify by visa type). DODREAM supports companies hiring foreign nationals through the entire HR process — from visa issuance to insurance reporting.
