Korea's national health insurance is not a flat fee, and what you owe depends less on your passport than on whether someone runs payroll for you. As of 2026 the contribution rate is 7.19% of monthly salary, split evenly with the employer, so a salaried worker pays 3.595% plus a long-term care surcharge. Foreign residents without a Korean employer pay a floor of ₩158,630 a month.
That one split explains most of the confusion online, where one person reports ₩90,000 a month and another ₩160,000 for what sounds like identical coverage. They are on different assessment systems.
Numbers that matter in 2026
- Health insurance rate: 7.19% of salary, halved between employee and employer
- Long-term care insurance: 0.9448% of income, billed alongside it
- Average employee's own share: ₩160,699 a month
- Premium floor ₩20,160 a month; employee ceiling ₩4,591,740 a month
- Foreign regional subscribers: ₩158,630 a month, or ₩79,315 on a D-2 or D-4 student visa
How Korea sets the 2026 premium rate
The Health Insurance Policy Deliberation Committee (건강보험정책심의위원회) fixed next year's number at its meeting on 28 August 2025, lifting the rate 0.1 percentage points to 7.19% of salary from 7.09%, an increase of 1.48% that the Ministry of Health and Welfare published in the same notice. Workplace subscribers (직장가입자) and their employers each carry 3.595%, deducted at source.
Long-term care insurance (장기요양보험) rides on the same deduction and is the line most people forget when they budget. The 2026 rate is 0.9448% of income, up from 0.9182%, which the ministry also states as 13.14% of the health premium itself. Average household cost: ₩18,362 a month, ₩517 more than in 2025.
The table below shows what moved between the two years, which is the fastest way to sanity-check a payslip that suddenly grew in January.
| Item | 2026 | 2025 |
|---|---|---|
| Health insurance rate | 7.19% | 7.09% |
| Long-term care rate (of income) | 0.9448% | 0.9182% |
| Average employee's own share (month) | ₩160,699 | ₩158,464 |
| Average regional household premium (month) | ₩90,242 | ₩88,962 |
| Minimum premium (month) | ₩20,160 | ₩19,780 |
The averages tell you that employees pay nearly twice what regional households pay on average, and that the year-on-year rise is small in absolute terms: ₩2,235 a month for the average employee, ₩1,280 for the average regional household.
Both ends of the scale are capped. No household pays under ₩20,160 a month, and no workplace subscriber pays more than ₩4,591,740 as their own share, against a combined employer-plus-employee ceiling of ₩9,183,480. The same ₩4,591,740 ceiling applies to the separate premium levied on non-salary income such as interest, dividends and rent.
The arithmetic on a ₩4,000,000 salary
Take a foreign employee on an E-7 or F-2 visa earning ₩4,000,000 a month in 2026. Health premium: ₩4,000,000 × 7.19% = ₩287,600, of which the employee's half is ₩143,800. Long-term care: ₩4,000,000 × 0.9448% = ₩37,792, halved to ₩18,896.
Total deducted from the payslip: ₩162,696 a month, or ₩1,952,352 over a year. At about ₩1,417 to the US dollar in mid-August 2026, that is roughly $115 a month. The employer contributes an identical ₩162,696, so the true cost of covering that worker is ₩325,392 a month, a figure worth knowing during salary negotiation because gross-versus-net offers in Korea often hinge on it.
Expressed as a single rate, an employee hands over 4.0674% of gross salary (3.595% + 0.4724%). Multiply your monthly gross by that and you have your combined deduction without touching a calculator twice. It sits alongside national pension, employment insurance and income tax on the same payslip, so the total statutory deduction is considerably higher than the health line alone. If you are budgeting a whole month rather than one deduction, our breakdown of the monthly cost of living in Seoul with rent puts this figure next to housing, transport and food.
Korean health insurance cost for foreign residents without an employer
Everyone not on a Korean payroll lands in the regional system (지역가입자), where premiums are assessed on income and property rather than salary. Foreigners face an extra rule here that Korean nationals do not.
The National Health Insurance Service applies a floor: if a foreign or overseas-Korean regional subscriber's calculated premium comes out below the average premium as of November of the previous year, the average is charged instead for the whole of the following calendar year. The legal basis is Ministry of Health and Welfare Notice No. 2019-151 of 11 July 2019. In practice this means most foreign residents with no Korean income and no Korean property pay the average, not a small assessed amount.
For 2026 that average is ₩158,630 a month, made up of ₩140,210 in health insurance and ₩18,420 in long-term care, published by NHIS as a 3.80% rise on the previous year. Annualised, that is ₩1,903,560, or about $1,344 at mid-August 2026 rates. Some English-language guides still quote around ₩142,000; that figure is the health-only component of an earlier year and omits long-term care.
Students get a statutory discount. Holders of D-2 (degree study) and D-4 (general training) visas, along with overseas-Korean students and F-4 nationals enrolled at qualifying schools, pay 50%, which works out to ₩79,315 a month in 2026.
Enrolment is not optional. Foreigners staying longer than six months have been compulsorily enrolled as regional subscribers since 16 July 2019, and D-2 holders have been enrolled from arrival, with no six-month wait, since 1 March 2021.
The comparison below answers one question: for a given situation, what leaves your account each month in 2026?
| Situation | Own share (KRW, 2026) | Employer pays a matching half |
|---|---|---|
| Employee, ₩3,000,000 salary | 122,022 | Yes |
| Employee, ₩4,000,000 salary | 162,696 | Yes |
| Employee, ₩6,000,000 salary | 244,044 | Yes |
| Foreign regional subscriber, no Korean assets | 158,630 | No |
| D-2 or D-4 student | 79,315 | No |
| Statutory minimum premium | 20,160 | No |
Run the two systems against each other and a crossover appears at about ₩3,900,000 a month in salary: ₩3,900,000 × 4.0674% = ₩158,629, essentially the foreign regional floor to the won. Below that salary, being on a payroll costs less than sitting in the regional pool. Above it, the payroll deduction is nominally higher, but you also gain an employer paying an equal amount and the coverage is identical.
So the practical position: if you are choosing between a low-paid contract job and freelancing on an F-visa, the payroll route is cheaper for health cover until roughly ₩3.9 million a month. Past that, the difference is a rounding error against the tax and pension consequences of the same choice.
Where this fails: the ₩158,630 figure is a floor, not a flat rate. Anyone with Korean-registered property or meaningful assessed income is billed on the standard regional formula instead, where property is valued at ₩211.5 per point in 2026. A foreign resident who owns an apartment in Seoul can pay several times the average, up to the ₩4,591,740 monthly ceiling.
What the premium buys: your share of each bill
Paying the premium does not make treatment free. The Health Insurance Review and Assessment Service sets the patient's share of covered services by facility type, which is why the same consultation costs different amounts at a neighbourhood clinic and at Severance.
| Setting | Patient's share of covered cost |
|---|---|
| Inpatient admission (all facility types) | 20% |
| Tertiary general hospital, outpatient | 100% of consultation fee + 60% |
| General hospital, outpatient | 50% urban / 45% rural |
| Hospital, outpatient | 40% urban / 35% rural |
| Clinic (의원), outpatient | 30% |
| Pharmacy | 30% |
The pattern is deliberate: the tier system prices you out of walking into a university hospital for a sore throat. A ₩20,000 covered consultation at a local clinic costs you ₩6,000; the same complaint taken to a tertiary hospital costs the full consultation fee plus 60% of everything else, before any referral penalty.
The percentages apply only to covered (급여) services. Non-covered items, which include most cosmetic procedures, private hospital rooms, many advanced imaging scans and a long list of dental work, are billed at 100% and do not count toward any cap. This is the single biggest gap between what people expect and what they are handed at the payment desk.
The annual out-of-pocket cap, and the arithmetic behind a refund
Covered costs are capped per calendar year through the 본인부담상한제, scaled by income decile. For treatment dated 1 January to 31 December 2026 the ceilings are:
| Income decile | Standard cap (KRW, 2026) | Cap after 120+ days in a long-term care hospital |
|---|---|---|
| 1st | 900,000 | 1,430,000 |
| 2nd–3rd | 1,120,000 | 1,810,000 |
| 4th–5th | 1,730,000 | 2,450,000 |
| 6th–7th | 3,260,000 | 4,040,000 |
| 8th | 4,460,000 | 5,800,000 |
| 9th | 5,360,000 | 6,980,000 |
| 10th | 8,430,000 | 10,960,000 |
The spread from ₩900,000 to ₩8,430,000 is the point of the scheme: the same hospital stay costs a low-income household a ninth of what it costs a top-decile one. The 1st-decile ceiling has moved up steadily, from ₩870,000 in 2024 to ₩890,000 in 2025 and ₩900,000 in 2026.
Worked through: a 5th-decile resident is admitted for surgery generating ₩12,000,000 in covered charges. The 20% inpatient share is ₩2,400,000. The 2026 cap for deciles 4–5 is ₩1,730,000, so ₩670,000 is returned in the post-year reconciliation NHIS runs on the previous year's records. Add ₩900,000 of non-covered private-room charges and that ₩900,000 stays yours, because non-covered items sit outside the cap entirely. Total real outlay: ₩2,630,000, not ₩1,730,000.
Four ways the bill goes wrong
Dependents no longer join on arrival. Since April 2024 a foreign family member must have lived in Korea for six consecutive months before being added to a subscriber's coverage. The exception is narrow and important: a workplace subscriber's spouse and children under 19 are exempt from the waiting period. NHIS figures show the rule bit quickly, with Chinese dependents falling from 111,059 in March 2024 to 106,243 a year later.
Arrears follow you to the immigration desk. Immigration checks health-insurance arrears for registered foreign nationals aged 19 and over when they apply to extend a stay, operating the check at 38 offices nationwide. Applicants clear of arrears receive the normal permission for their visa category, between two and five years. Applicants in arrears are held to six months or less as a rule, which turns an unpaid ₩158,630 into a permanent scheduling problem.
Benefits stop while you are behind. During an arrears period the account is suspended and treatment is charged at the full undiscounted rate at the counter, then reclaimed only after the balance is settled. Late payment also accrues interest on the outstanding amount.
Working holiday holders sit in a different sequence. H-1 arrivals are not enrolled from day one and need to bridge the gap before mandatory enrolment kicks in; that timing is covered separately in our guide to working holiday insurance and the month-six switch.
Which situation you are in
- On a Korean payroll: multiply gross monthly salary by 4.0674%. That is your deduction, and your employer pays the same again.
- D-2 or D-4 student: ₩79,315 a month in 2026, billed from arrival rather than after six months.
- Foreign resident, no Korean employer, no Korean property: ₩158,630 a month, set by the November average rule, not by your actual income.
- Foreign resident who owns property here: the average does not apply; assessment runs on income and property points at ₩211.5 each, with a ₩4,591,740 monthly ceiling.
Questions that come up before the first bill
How much does health insurance cost per month for a foreigner in Korea?
₩158,630 a month in 2026 for a regional subscriber with no Korean employer, comprising ₩140,210 in health insurance and ₩18,420 in long-term care, per NHIS. Employees pay 4.0674% of salary instead, which averaged ₩160,699 a month across all workplace subscribers in 2026.
Is enrolment mandatory, or can I use private insurance instead?
Mandatory. Foreigners staying longer than six months have been enrolled compulsorily as regional subscribers since 16 July 2019, and D-2 students since 1 March 2021. A private travel or expat policy does not substitute for enrolment; it can sit on top to cover the 20–60% patient share and non-covered items.
What happens if I stop paying?
Two things at once. Coverage suspends, so treatment is billed in full at the counter, and immigration limits any extension application to six months or less while arrears stand, checked at 38 offices for anyone aged 19 or over.
Can my spouse be covered on my premium?
Yes, as a dependent, at no extra premium. Since April 2024 a foreign dependent must have resided in Korea for six consecutive months first, except for the spouse and under-19 children of a workplace subscriber, who are exempt from that wait.
Is there a maximum anyone can pay?
Yes. The 2026 ceiling on a workplace subscriber's own share is ₩4,591,740 a month, against a combined ceiling of ₩9,183,480 including the employer half. The same ₩4,591,740 caps the premium charged on non-salary income.
The one action worth taking in your sixth month in Korea is confirming which subscriber category NHIS has assigned you, because that assignment, not your visa type, decides whether you are billed 4.0674% of a salary or a flat ₩158,630. NHIS runs a multilingual line on 1577-1000 and an English service through its Center for Foreign Residents. Figures here are the published 2026 rates and averages; your own assessment depends on registered income, property and household composition, and this is general information rather than personalised financial or immigration advice.
