If your paycheck deduction looks a little bigger in January, the health insurance premium increase 2026 is likely the reason. South Korea’s National Health Insurance (NHIS) premium rate has been set at 7.19% for 2026, so both employee and regional subscribers will pay slightly more each month.
It’s the first increase in three years, so here’s exactly how much more you’ll pay and why.
This article covers the exact size of the health insurance premium increase 2026, when it takes effect, how much more employees will pay, and how premiums are calculated for regional (self-employed) subscribers. In short: Korea’s 2026 health insurance premium rate rises 0.1 percentage points to 7.19%, effective from the January 2026 billing cycle.
How big is the health insurance premium increase 2026 in Korea?
Korea’s 2026 health insurance premium rate is 7.19%, up 0.1 percentage points (1.48%) from 7.09% in 2025.
The premium rate is the percentage applied to a subscriber’s monthly wage or income to determine their monthly National Health Insurance payment. This is South Korea’s mandatory public health insurance system, run by the National Health Insurance Service (NHIS, 국민건강보험공단), covering nearly all residents including registered foreigners.
The Ministry of Health and Welfare’s health insurance policy committee approved the increase in August 2025, and the new rate applies from the January 2026 billing cycle.
A hike closer to 2% was initially reviewed, but officials scaled it back to 1.48% due to concerns about household affordability amid high inflation. Because the rate had been frozen at 7.09% for three straight years (2023-2025), this is the first increase since then.

How much more will employee subscribers pay in 2026?
Employee subscribers (직장가입자) pay half of the 7.19% rate — 3.595% — while their employer covers the other half.
According to NHIS, the average monthly premium employees pay out of pocket rises from KRW 158,464 (about $111) in 2025 to KRW 160,699 (about $113) in 2026 — an increase of KRW 2,235 per month. Here’s the breakdown.
| Category | 2025 | 2026 |
|---|---|---|
| Premium rate | 7.09% | 7.19% |
| Employee’s share | 3.545% | 3.595% |
| Avg. monthly premium (employee-paid) | KRW 158,464 (~$111) | KRW 160,699 (~$113) |
Your actual bill depends on your monthly wage, so treat these figures as averages, not your exact deduction. This health insurance premium increase 2026 applies equally to every employee subscriber, regardless of industry or company size.
Your actual payslip amount will differ based on your individual salary. Check your HR department or the NHIS “The건강보험” app for your exact figure.
How is the premium calculated for regional (self-employed) subscribers?
Regional subscriber premiums are based on income and property, and the 2026 average monthly premium is KRW 90,242 (about $63).
A regional subscriber’s premium is calculated by adding an income-based amount (monthly income × premium rate) to a property-based amount (property assessment points × the value per point). Regional subscribers (지역가입자) are people not covered through a workplace — the self-employed, freelancers, retirees, and unemployed household heads. Unlike employees, their premium reflects business income, financial income, and property, not just wages. For regional subscribers, this health insurance premium increase 2026 is layered on top of both income and property assessments.
According to Korea’s Ministry of Government Legislation, the household’s monthly premium combines both elements. The average monthly premium for regional subscribers rises from KRW 88,962 (~$62) in 2025 to KRW 90,242 (~$63) in 2026, an increase of KRW 1,280.

Why is the premium rate going up?
Because the health insurance fund’s revenue base has weakened, while spending needs are rising to strengthen regional and essential medical care.
The Ministry of Health and Welfare said it weighed both a weakened revenue base and future spending tied to the new administration’s push to strengthen regional and essential medical services. At the same time, it factored in household affordability amid high inflation, settling on 1.48% — lower than the roughly 2% increase initially discussed.
Because the rate stayed flat at 7.09% from 2023 through 2025, this marks the first adjustment in three years. The long-term care insurance rate is rising too, from 0.9182% in 2025 to 0.9448% in 2026 — long-term care insurance (a mandatory add-on that funds elder and disability care, charged as a percentage of your health insurance premium).
Reason: weaker NHIS revenue base + higher spending on regional and essential care
Scaled back from an initially discussed ~2% to a final 1.48%
Long-term care insurance rate also rises, from 0.9182% to 0.9448%
Overall, this health insurance premium increase 2026 reflects an effort to balance NHIS sustainability with household affordability.
