Increase in National Health Insurance Premium (effective from January 1, 2018)

December 26, 2017  |  Social Security Programs

The monthly National Health Insurance premiums borne by an employer and its employees are calculated by multiplying each employee’s monthly salary Income (excluding non-taxable income) by the insurance premium rate.   Long-term Care Security for the Elderly Insurance premium is imposed together with the National Health Insurance premium, and the premium is calculated by multiplying national health insurance premium by the insurance premium rate (i.e., surcharge of the national health insurance premium).

Effective from January 1, 2018, the insurance premium rate of the national health insurance will be increased from 6.12% to 6.24% of monthly salary income.  Each employer and employee portion rise from 3.06% to 3.12%, respectively.   In addition, the insurance premium rate of the long-term care security for the elderly insurance will also be increased from 6.55% to 7.38% of the national health insurance premium.

For example:

With the monthly salary income (excluding non-taxable income) of KRW 5,000,000, the insurance premiums will increase as shown below.

Year 2018 Year 2019
National Health Insurance KRW 5,000,000*3.06% = 153,000 KRW 5,000,000*3.12% = 156,000
Long-term Care Security for the Elderly Insurance KRW 153,000*6.55% = 10,020 KRW 156,000*7.38% = 11,510
