Korea Health Insurance for Foreigners (2026): At Least ₩158,630 a Month After Six Months — Students, Workers, and What Happens If You Don't Pay

Last updated: 30 September 2026. Premium figures are from the National Health Insurance Service (국민건강보험공단, NHIS) notice of its 2026 rates and its page on premiums for foreign regional subscribers, which applies the Ministry of Health and Welfare's standard for long-term foreign residents (고시 제2019-151호). The rules on enrolment, dependants and arrears are read from the National Health Insurance Act (국민건강보험법) Article 109 and its Enforcement Decree Articles 76-2 to 76-6, as in force in September 2026. Student figures are from Korean universities' 2026 notices. Dollar figures use about ₩1,360 to US$1 and are approximate. This is a guide to the rules, not legal advice.

Search "health insurance for foreigners in Korea" and the English pages have mostly caught up on one number: ₩158,630 a month. What they rarely explain is where that number comes from, why a student pays half of it, why a minimum-wage office worker pays less than a jobless foreigner, and what actually happens if you stop paying — a rule the Constitutional Court found unconstitutional in 2023 and the National Assembly rewrote in 2024, effective April 2025. English pages rarely describe the current version.

The Korean sources answer all of it. NHIS's 2026 rate notice sets the average premium for foreign regional subscribers at ₩158,630 a month (about US$117), up 3.8% from ₩152,790: ₩140,210 health insurance plus ₩18,420 long-term care. That average is also the minimum, and Article 109 of the National Health Insurance Act puts almost every registered foreigner into the system after six months. Here is who pays what, and the exact rule on arrears.

Where ₩158,630 comes from

The NHIS page on premiums for foreign regional subscribers (재외국민 및 외국인 지역보험료 부과기준) reproduces the ministry's standard in two sentences. Foreign regional subscribers are charged "내국인 지역가입자와 동일한 기준에 따라" — on the same basis as Korean regional subscribers, from income and property. Then the catch: "산정된 보험료가 전년도 11월말 전체 평균보험료보다 적은 경우에는 그 평균보험료를 다음해 1월~12월분 보험료에 부과" — if the calculated premium is lower than the average premium of all subscribers at the end of the previous November, that average is charged for January to December of the following year.

Most newly arrived foreigners have no Korean income or property on record, so the average becomes the bill:

From ₩152,790 in 2025 to ₩158,630 in 2026 is ₩5,840 a month, about ₩70,000 a year. If you have Korean income without being an employee — a business owner on a D-8 visa, for instance — your calculated premium (income × 7.19%, plus property points × ₩211.5, plus long-term care) can exceed the average, and you pay the higher figure.

Two groups sit outside the floor entirely. Permanent residents (F-5) and marriage migrants (F-6) are charged exactly like a Korean household — the NHIS page says so directly — so a low-income F-6 household can pay far less than ₩158,630. And where the head of household is a recognised refugee or a minor, the premium is whichever is higher of the Korean calculation and the national monthly minimum, not the average.

Who is enrolled, and from when

Article 109(3) of the National Health Insurance Act makes a registered foreigner who is not an employee a regional subscriber once they hold a listed visa status and have lived here for the period set by ministry ordinance: six months, compulsory since 16 July 2019. Before that, a foreigner could decline to join.

The Enforcement Decree (Article 76-2) sets the start date in two ways. If you qualify by having lived in Korea for the required period, you join on the day the six months end. If your status is one where continuous residence can be expected from the start, you join on the day you entered Korea. In practice that splits foreigners like this:

• Six-month wait: most visas — D-4 language students, D-10 job seekers, E-2 teachers between jobs, F-4 overseas Koreans, H-1 working holiday makers and the rest of the list NHIS publishes, from C-0 to H-2.
• From arrival: D-2 university students and D-4 students at primary and secondary schools, who have been enrolled from their alien registration since 1 March 2021; and, among others, permanent residents (F-5) and marriage migrants (F-6).
• From the first day of work: anyone employed at a workplace covered by national health insurance becomes an employee subscriber under Article 109(2), whatever the visa, with no waiting period. E-9 factory workers, E-7 professionals and E-2 teachers with a school contract are all in this group.

The one way out is narrow. Article 109(5) allows an exclusion (가입 제외) if foreign law, a foreign insurer or an employment contract gives you cover equivalent to Korean national health insurance benefits. NHIS decides what counts, and the exclusion normally runs from the day you apply. It is not a way to swap the national scheme for a cheap travel policy.

Coverage ends by itself in three situations under the same Article 76-2: the day after your permitted stay expires, the day after a deportation order, or — for regional subscribers — the day after you left Korea if you stay abroad for more than a month. Tell NHIS when you leave for good; premiums paid for months after you lost coverage can be refunded.

Students: ₩79,320 in 2026

International students are the group that notices this premium most, because it arrives on day one. The NHIS page lists the reduction plainly: 유학(D-2), 일반연수(D-4), 재외국민 유학생, 재외동포(F-4) 유학생: 50% — overseas Korean and F-4 students qualify only at schools and universities, not at graduate schools.

Half of ₩158,630 is ₩79,315, and Korean universities' notices for 2026 give the student premium as ₩79,320 a month. Hanyang University's international office (guide updated 1 March 2026) gives the change as ₩76,390 → ₩79,320; ₩76,390 was the 2025 student figure, half of ₩152,790. Sogang University (26 February) and Sungshin Women's University (6 March) published the same ₩79,320.

The timing differs inside the reduction. A D-2 degree student pays from the first month; a D-4 language student pays nothing to NHIS for six months, then joins at the same ₩79,320. Universities often add their own group insurance — Sogang's notice ties its benefits to having no NHIS arrears.

Employees: 7.19%, split in half

For anyone on a Korean payroll the floor does not exist. NHIS's 2026 notice sets the employee health insurance rate at 7.19% of monthly pay (보수월액), up 1.48% from 7.09% in 2025, and states that the subscriber and the employer each pay 50%. Long-term care insurance is charged on top: the 2026 rate is 0.9448%, and the notice gives the formula as health premium × 0.9448% ÷ 7.19% — about 13.1% of the health premium. It is also split half and half.

For a full-time worker on 2026's monthly minimum wage of ₩2,156,880, that works out on our own calculation to about ₩77,530 of health insurance and ₩10,180 of long-term care deducted from pay, roughly ₩87,700 a month (about US$64), with the employer paying the same again. That is the quiet oddity of the system: a foreigner on the minimum wage pays barely more than half of what an unemployed foreigner of the same nationality pays as a regional subscriber, because the employer carries the other half and there is no floor for employees. Your payslip (임금명세서) should show the deduction as 건강보험 and 장기요양보험 on separate lines.

Dependants are where the 2024 change bites. Since 3 April 2024, Article 109(4) requires a foreign dependant (피부양자) of an employee to have lived in Korea for six months before joining the employee's cover — except for the spouse and children under 19 (including the spouse's children), who can be added from arrival. Parents brought over for treatment now wait six months. For regional subscribers, the rule is different again: each foreigner is billed as their own household unless they apply to add a spouse or children under 19 to a single household, which then pays one premium.

What the insurance covers, and what it does not

Once enrolled, a foreigner gets the same benefits as a Korean subscriber: consultations, tests, surgery, hospital stays, prescription drugs and the national health check-up programme, at the co-payment rates the Enforcement Decree sets by type of institution. For an outpatient visit in a city (동) area that is 30% at a clinic (의원), 40% at a hospital (병원) and 50% at a general hospital (35% and 45% in 읍·면 areas), and at a tertiary hospital the full consultation fee plus 60% of the rest; for an inpatient stay it is 20% (plus half of meal costs); at the pharmacy, 30%. A clinic first visit that costs ₩18,840 at the full national fee (see what a doctor costs without insurance) becomes a bill of a few thousand won.

What it does not cover is 비급여 (non-covered) care: cosmetic procedures, most vision correction, upgraded rooms, many dental treatments, some scans without a qualifying reason, and many newer procedures. The hospital sets those prices itself — our guides to LASIK, dental implants and MRI scans show what they cost. Nor is it travel insurance: it pays nothing abroad.

Since 20 May 2024 Korean hospitals and clinics must check the patient's identity, so bring your residence card (외국인등록증), your passport, or the NHIS mobile health card. Without one you can be charged as uninsured at the desk — bring the ID and the receipt back within 14 days to have the bill settled at the insured price.

If you don't pay: one month for most, three for a few

From 2019, Article 109(10) stopped benefits for a foreign regional subscriber from the first missed payment, with no notice and no exceptions. On 26 September 2023 the Constitutional Court ruled unanimously (2019헌마1165) that this violated equal treatment. The amended act (법률 제20505호), promulgated on 22 October 2024, took effect on 23 April 2025, with the detail in two new decree articles:

• Article 76-5: benefits can be withheld once a premium has been unpaid for one month — the same threshold as for Koreans.
• Article 76-6(1), for D-8, E-1, E-3, E-4, E-5 and F-2 holders only (the decree's Annex 6-2): NHIS may continue to pay benefits while the total number of unpaid monthly premiums is fewer than three. Months you have since paid do not count, and neither does how long they were overdue.
• Article 76-6(2), same six statuses only: treatment received while benefits were suspended is recognised retroactively if you pay the arrears in full by the payment deadline of the month in which two months have passed since NHIS notified you.

In plain terms: for students, job seekers, F-4 holders and most other foreign regional subscribers, one overdue month is enough to lose cover until the arrears are paid, with no three-month grace. The grace period and the retroactive rescue apply only to the six business, professional and residence statuses listed above. Once benefits are suspended, the hospital bills you the full amount, including NHIS's share.

The other consequence is at immigration. The Ministry of Justice checks tax and health-insurance arrears when a registered foreigner aged 19 or over applies to extend their stay. Its own page states that if the arrears are paid, the extension proceeds normally; if not, the extension is restricted — in principle to six months or less. The system has run since 2019. Pay before the appointment, and bring the NHIS payment certificate (완납증명서) if the officer asks.

How to pay and check your premium

The bill goes to the address on your alien registration. For foreign regional subscribers, Article 109(8) makes it due by the 25th of the month before the month it covers. Pay by transfer to the bill's virtual account, by card, at a bank, ATM or convenience store — or set up automatic debit from a Korean bank account, the easiest way never to miss a month.

To check what you owe, use the NHIS website (nhis.or.kr, which has an English section), the NHIS app "The건강보험", or call 1577-1000 and press 6 for English, Chinese, Vietnamese or Uzbek, or dial 033-811-2000. NHIS branch offices handle household changes, dependant applications, exclusions and certificates in person; bring your residence card.

The honest part: when ₩158,630 is the wrong number for you

• Employees, F-5 and F-6 holders: it is not your number. You pay a percentage of pay, or the Korean household calculation.
• It can be higher. A self-employed foreigner with Korean business income or Korean property is billed on the calculated amount when that exceeds the average.
• It is not a fee for a policy you can refuse. Since 2019 enrolment is compulsory. Private insurance does not replace it unless NHIS accepts an exclusion application.
• It changes every January. Check the current year's NHIS notice before you budget.
• Short stays are outside it. A tourist or a visitor here for less than six months on a non-student visa is not enrolled and pays nothing — and is billed as uninsured at a hospital, which is what our clinic and emergency-room cost guide is about.

FAQ

Q: How much is health insurance for foreigners in Korea in 2026? A foreign regional subscriber — a registered foreigner without a Korean employer — pays at least ₩158,630 a month in 2026, which is ₩140,210 of health insurance plus ₩18,420 of long-term care. It is the previous November's average premium, charged whenever the premium calculated from your Korean income and property is lower. D-2 and D-4 students pay half, ₩79,320.

Q: When does NHIS enrolment start for foreigners? After six months' residence for most registered foreigners, a rule in force since 16 July 2019. D-2 university students and D-4 primary and secondary school students are enrolled from their alien registration, and employees from their first day of work.

Q: How much do foreign employees pay for health insurance in Korea? In 2026 the health insurance rate is 7.19% of monthly pay, split equally with the employer, so the employee pays 3.595%. Long-term care adds 0.9448% of pay, also split, calculated as health premium × 0.9448 ÷ 7.19. On the 2026 minimum monthly wage that is about ₩87,700 deducted per month.

Q: What happens if I don't pay my Korean health insurance premium? Since 23 April 2025, NHIS may withhold benefits once a premium is a month overdue. Only D-8, E-1, E-3, E-4, E-5 and F-2 holders keep cover while fewer than three monthly premiums are unpaid and can have treatment recognised retroactively by paying in time; for D-2, D-4 and most other visas, one overdue month is enough. Once benefits stop, you pay the full hospital bill. Immigration also restricts stay extensions, in principle to six months or less, until the arrears are paid.

Q: Can my family be covered? If you are an employee, your spouse and children under 19 can be added as dependants from arrival; other relatives must first live in Korea for six months (the rule since 3 April 2024). If you are a regional subscriber, you can apply to put your spouse and children under 19 in one household with a single premium.
