How it began
Korea launched employee medical insurance for firms with 500 or more workers in 1977 and reached the whole population in 1989, just twelve years later (Kwon, 2009). Hundreds of separate funds merged into a single National Health Insurance Service in 2000 (Lee, 2003). The system rests on the principles of social insurance, with low contributions, broad coverage and recurring fiscal strain (Jeong, 2011).
Employees
Employees pay 7.19% of monthly pay in 2026, split evenly with the employer, plus long-term care at 0.9448/7.19 of the health premium. Income outside salary above KRW 20 million a year adds a separate premium. On KRW 2 million a month the worker pays KRW 81,340. The rate rose 0.1 point from 7.09%, the first increase in three years. See four major social insurances.
| Item | 2026 | Worker share |
|---|---|---|
| Health premium | 7.19% of pay | 3.595% |
| Long-term care | Premium × 0.9448/7.19 | Half |
| Non-wage income | Over KRW 20m/yr | Full |
Self-employed and dependents
Regional members pay on income plus asset points (KRW 211.5 per point in 2026); since February 2024 the basic asset deduction is KRW 100 million and cars no longer count. Dependents of employees pay nothing, but since September 2022 anyone with income over KRW 20 million a year or assets above thresholds becomes a regional member—why bills often jump after retirement. Retirees may keep employee status for up to 36 months.
Linking premiums to benefits
The out-of-pocket maximum refunds high annual spending, indemnity insurance covers gaps, and long-term care insurance supports older adults. If income falls, ask NHIS to adjust your premium.
