Health Insurance in Korea for Foreigners: How NHIS Works (2026)

Last verified: 2026-08-27 05:47 KST

Korean health insurance is not something you sign up for. For most foreign residents it attaches to you by law, the bill follows, and unpaid premiums become an immigration problem rather than a medical one.

This page gives the 2026 rates from the National Health Insurance Service’s own published figures, the legal basis for who is enrolled and when, and the two windows — one 14 days wide, one 5 days wide — where knowing the rule saves you money or a wasted trip to immigration.

The 2026 numbers

NHIS publishes its contribution rate and its point value directly. These are the current figures.

National Health Insurance contribution basis, from NHIS published rates. Checked 2026-08-27.
Insured type	How it is calculated	2026 figure
Employee insured (직장가입자)	Monthly average wage × contribution rate	7.19%, shared with the employer
Self-employed insured (지역가입자)	(Monthly income × contribution rate) + (property contribution points × value per point)	7.19% on income, plus 211.5 KRW per property point

Two things follow. First, the employee rate rose from 7.09%, where it had sat for 2023, 2024 and 2025, to 7.19% in 2026 — the first increase in three years. Second, because the employee rate is shared with the employer, the deduction from your salary is roughly 3.6% of your monthly wage rather than 7.19%.

The self-employed calculation has two halves rather than one. Income is charged at the same 7.19% rate an employee pays, and only property is converted into contribution points and multiplied by 211.5 KRW per point. Vehicles are not part of it: the automobile component of the self-employed premium was abolished by Presidential Decree No. 34217, in force from 13 February 2024 and applied from the February 2024 premium. That is why two people with identical salaries can still receive very different bills — the difference is property, not the car in the driveway. Checked 2026-09-04.

Who is enrolled, and when

If you work for a Korean employer

NHIS states that foreigners and overseas Koreans residing and working at an insured company are compulsorily subscribed. Your employer registers you, the premium is shared, and your half is deducted from salary. There is nothing for you to do.

If you do not

Here is the rule most newcomers have never seen written down. Per NHIS: any foreigner or overseas Korean who has stayed in Korea for over six months is subject to mandatory subscription to health insurance, effective from 16 July 2019. Checked 2026-08-27.

The six-month rule is a general starting point, not a personal coverage decision. Employment, dependent status, residence status and approved exclusions can change how you are enrolled. Ask NHIS to confirm your acquisition date rather than assuming you can wait six months without coverage.

The visa categories NHIS lists as covered are broad: D-1 through D-9, E-1 through E-7, E-9, E-10, F-1 through F-6, H-1 and H-2. If your status is on that list, plan for the premium rather than being surprised by it. Enrolment runs off your registration record, which is one more reason the residence card sits at the centre of your first months.

The 14-day window nobody mentions

If your employer provides equivalent medical coverage — under foreign law, under a foreign insurance policy, or under your employment contract — you may be able to be excluded from the employee scheme. The legal basis is the enforcement decree of the National Health Insurance Act, article 76, and article 61 of the same law’s enforcement regulation.

The mechanics are where the money is. NHIS states that if the Employee Health Insurance Withdrawal Application is submitted within 14 days of the date the acquisition of eligibility was reported, the date of acquisition becomes the date of loss. In plain terms: file inside 14 days and it is as if you were never enrolled. File later and you have premiums to settle. Checked 2026-08-27.

This matters most to people arriving on a package that already includes international private medical cover — some academic, diplomatic-adjacent and multinational postings. If that describes you, ask your HR department about the withdrawal application in your first week, not your second month.

Dependents: the thresholds, and the trap for couples

A spouse or family member can be covered as a dependent of an employee insured person rather than paying separately, if income and property fall under set thresholds.

Income: total income across all types under 20 million KRW a year. If there is a business registration, no business income; if there is no business registration, annual business income under 5 million KRW.
Property: property tax base under 540 million KRW. Between 540 and 900 million, annual income must be 10 million KRW or less. For a sibling, the property tax base must be 180 million KRW or less.
Relationship: spouse, lineal ascendants and descendants including the spouse’s, and unmarried siblings meeting the income and property tests who are over 65 or under 30 — with the age limit waived for disabled persons and those eligible for national merit compensation.

The trap: if the dependent is married, both spouses must meet the income requirements — and if either fails, both are excluded from dependent status. A working spouse can therefore disqualify a non-working one. Checked 2026-08-27.

Why unpaid premiums are an immigration problem

NHIS states that paying contributions is a duty of the insured, and that where the insured fails to pay, NHIS may collect by authority under the law. That is the financial half. The immigration half is the one foreign residents underestimate.

The Korea Immigration Service operates a formal health insurance arrears confirmation system. Arrears can surface when you apply for an extension or a change of status.

And there is a timing gap that produces avoidable trouble at the counter. HiKorea’s reservation notice instructs applicants who paid overdue premiums within the last five days — at a utility payment machine or through internet giro at giro.or.kr — to bring the receipt. Payment records take time to propagate, and an officer may still see arrears you have already cleared. Checked 2026-08-27.

So the sequence is: pay early enough that the record catches up, and if you could not, carry the paper. Booking mechanics are in our HiKorea appointment guide.

Practical order

If you are employed, check your first payslip for the deduction. Roughly 3.6% of gross is the expected figure at 2026 rates.
If you have equivalent cover through your employer or a foreign scheme, ask about the withdrawal application immediately — the window is 14 days from the reported acquisition date.
If you are not employed, ask NHIS when coverage starts for your residence status and budget for it rather than waiting for a letter you may not be able to read.
Set up autopay from a Korean account in your own name. NHIS bills arrive on a schedule that does not care whether you understood the envelope.
Never let arrears run into an extension application.
If you have dependents, check both spouses’ income against the thresholds before assuming coverage.

What this page does not cover

Individual local-insurance premiums depend on your circumstances. NHIS guidance for foreigners also describes a minimum tied to the average premium for many foreign residents, with different treatment for F-5/F-6 holders and reductions for specified groups. Do not estimate your bill from income and property alone. Confirm the amount and any reduction directly with NHIS. These contribution distinctions were checked October 6, 2026; treatment co-payments and long-term care insurance are separate.

What the 119 ambulance costs and what the hospital afterwards costs are two different questions — the first is in our Korean help lines guide.

Verification note. On September 24, 2026 an AI-assisted check compared the 7.19% rate an employee pays and the 211.5 KRW per property point against the NHIS (except HiKorea, which cannot be checked automatically), and confirmed the official sources linked in this guide still resolve to the same pages. I publish this guide under my own name and am responsible for what it says. Rules and fees in Korea change often; if you spot something out of date, email hello@90dayskorea.com and it will be re-checked and corrected.
