● Korean statutory four major insurance contribution requirement and general practice for re-employed employees after the statutory retirement age
There is no material distinction between “post-retirement re-employment” and “employment after the statutory retirement age”, other than that the former is regarded as a retirement followed by re-hiring upon reaching the statutory retirement age.
In common practice, employers commonly hire individuals beyond their retirement ages under fixed-term or part-time arrangements, with compensation and benefits tailored to their roles. The distinction between re-employment of existing retirees and the hiring of new employees beyond retirement age is not material from a compliance perspective. The same rules on contract structure, tax, and social insurance contributions shall apply.
The employee’s age affects coverage under the four major social insurance programs as follows:
|
National Health Insurance (NHI) |
National Pension (NP) |
Unemployment Insurance (UI) |
Industrial Accident Compensation Insurance (IACI) |
|
Remains mandatory regardless of age, with standard employer and employee contributions |
Contributions are not required once the employee reaches the age of 60 in general * |
Will vary depending on whether a new hire or an existing employee working after reaching 65 ** |
Mandatory regardless of age |
(Notes)
* Individuals over the age of 60 who wish to increase their future pension benefits may apply for voluntary continued participation and continue making national pension contributions until the age of 65. However, in this case, the individual is required to pay the full 9% contribution solely on their own based on their standard monthly income, without any employer contribution).
** UI participation requirements-
1) For new hires aged 65 or older:
- Enrollment is required; however, unemployment benefits are not available.
- Both employees and employers are exempt from the 1.8% unemployment insurance contribution (0.9% each), and employer is responsible only for the Employment Stability and Vocational Competency Development contributions (ranging 0.25 ~0.85%).
2) For employees hired before the age of 65 who continue working after reaching 65
- Enrollment is required to be eligible for unemployment benefits.
- Both the employee and the employer must pay the 1.8% unemployment insurance contribution (0.9% each), and employer is required to continue paying Employment Stability and Vocational Competency Development contributions.
As s side note, employees aged 60 or older working in SMEs in Korea may be eligible for a 70% income tax reduction benefit for a period of three years starting from their 60th year (or from the date of initial employment if hired after reaching 60), provided certain conditions are met. A separate application must be prepared and submitted to receive this benefit.
