They contribute 4.5% of the monthly salary to the national pension fund. The employer and employee also contribute 2.945% and 0.55% of the average monthly wage as a national medical insurance premium and an unemployment insurance premium, respectively. In addition to the unemployment insurance, the employer contributes an insurance premium, which varies from 0.25% to 0.85% of an employee’s average monthly wage based on the number of employees. The long-term care insurance contribution is imposed on the national medical insurance premium at a 6.55% rate.

Payroll
There are specific rules for payroll and taxation in South Korea, depending upon the number of employees. Foreign employees are required to pay income tax in South Korea. The primary concerns for a foreign company that needs to comply with tax laws in South Korea are: individual income tax for employees in South Korea, social security costs, payroll tax, sales tax, employment insurance, social insurance programs, withholding tax, business tax, pension contributions and permanent establishment concerns.
Remote Payroll
A remote payroll in South Korea is where a foreign company, i.e. a non-resident company, payrolls a resident employee in South Korea. One option for a non-resident company to payroll its employees (local and foreign) in South Korea is to use a fully outsourced service like a GEO which will employ and payroll the staff on their behalf.
Local Payroll Administration
In some cases, a company will register their business in South Korea under one of the forms available, but prefer to have another company administer its payroll. This can be accomplished through a payroll provider. It is important to note that the company, as the Employer of Record, is still fully responsible for compliance with employment, immigration, tax and payroll regulations. But the payroll calculations, payments and filings can all be outsourced to the payroll provider.
Internal Payroll
Larger companies with a commitment to South Korea may wish to run their own local payroll for all employees, foreign and local. In order to accomplish this, they will have to complete incorporation, register the business and then hire the necessary staff. There will be a need for in country human resources personnel who have the background needed to manage a South Korean payroll, and can fulfill all tax, withholding, and payroll requirements.
This approach carries significant cost and requires some knowledge of local employment and payroll regulations. The company will need a local accounting firm and potentially legal counsel to ensure full compliance with South Korean employment laws.
