How Korean health insurance premiums are calculated
A plain-English overview of how NHIS premiums may be assessed for foreign residents.
Health insurance premiums can depend on whether you are insured through employment, registered as a dependent, or enrolled as a local subscriber. Income, property, household status, and minimum premium rules may matter depending on your category. Foreign residents should not ignore premium notices. If your income changed, you left Korea, your employer registered you, or your household details are wrong, contact NHIS and ask what evidence is needed to correct the record. Keep payment records and notices. Unpaid premiums can cause stress later when using medical services, extending stay, or settling final bills before departure.
