National Health Insurance for Foreigners in Korea: The 6-Month Rule and What You'll Pay

Julia came to Korea on an F-6 visa and spent her first months studying Korean, with no job yet. In month seven a letter arrived from the National Health Insurance Service (국민건강보험공단) with a bill for over ₩100,000.

She'd never signed up for anything. Was it a mistake?

It wasn’t a mistake. Since 2019, foreign residents who have lived in Korea for 6 months are enrolled in National Health Insurance automatically, and the premium starts whether or not you visit a doctor.

Two ways to be covered

Your situation How you’re covered What you pay
Employee (E-2, E-7, E-9, F visas with a job) Workplace subscriber (직장가입자) from your first day 3.595% of pay + long-term care, your employer pays the same
Not employed: students, spouses, freelancers, job seekers Regional subscriber (지역가입자), automatically after 6 months’ stay Based on income and property, with a minimum
Spouse or child of an insured employee Dependent (피부양자) Nothing extra

Students on D-2 and D-4 visas are enrolled from arrival and pay a reduced premium.

If you're not covered through a job, enrollment starts at the 6-month mark.

How much regional subscribers pay

Regional premiums are calculated from your income and property, but foreigners pay at least the average premium of all subscribers from the previous year, even with no income. In 2025, foreign households in regional insurance paid about ₩135,000 a month on average.

A spouse who isn't working gets her own regional bill at the foreign minimum.

The same spouse is registered as a dependent of a partner who's an employee, and pays nothing extra.

Since April 2024, foreign family members generally need to have lived in Korea for 6 months before they can be added as dependents. Spouses and children under 19 are exempt from that wait.

Employee earning ₩3,000,000 a month in 2026:

Health insurance 3.595% = ₩107,850 · Long-term care ≈ ₩14,170

Total ≈ ₩122,000 a month, with the employer paying the same again. A non-working spouse can be added as a dependent at no extra cost.

Why paying on time matters

Unpaid premiums are reported to immigration. Arrears can shorten or block your next visa extension, and benefits can be suspended while you owe money. If you leave Korea for a while, contact NHIS about pausing your coverage instead of letting bills pile up.

Using it

Show your ARC at any clinic or hospital. You pay a share of the cost, typically 30–60% for outpatient visits depending on the size of the hospital, and the insurance covers the rest. Your app-based insurance card (모바일 건강보험증) works too.
