South Korea has one of the most structured payroll environments in Asia. Monthly pay cycles, mandatory social insurance contributions, and a formal year-end tax reconciliation process mean there’s little room for ad hoc approaches. If you’re hiring in South Korea, you’ll need to understand the full compliance picture before your first pay run.
How payroll works in south korea
Salaries in South Korea are paid in South Korean Won (KRW) on a monthly basis. The standard pay date is the 25th of the month, though your employment contracts can specify a different date as long as it’s consistent and agreed upon in writing.
South Korean employment law is primarily governed by the Labour Standards Act, which sets out rules on working hours, pay, and termination. Standard working hours are 40 hours per week and 8 hours per day. Overtime is permitted but governed by strict rules under the Act, and additional pay applies for hours beyond the standard threshold.
The 2026 minimum wage is KRW 10,320 per hour, which translates to KRW 2,156,880 per month based on standard hours. These are floor rates. You can’t pay below them, and any contractual arrangement that does is void by law.
Employment contracts and registration
All employment contracts must be in Korean. Bilingual contracts are acceptable, but the Korean text controls in the event of a dispute. A written contract is mandatory, and hiring must be reported to the relevant authorities. There’s no legal maximum on probation length, but three months is the standard in practice.
Pay frequency and deadlines
Pay runs monthly and is typically processed for the 25th. Beyond the monthly pay cycle, there are several remittance deadlines you need to track across the different social insurance schemes.
Social insurance contributions are due by the 10th of the month following the pay period. Income tax withheld from employee wages follows the same rhythm. You need to remit both on time or face penalties from the National Tax Service and the relevant social insurance bodies.
When an employee’s employment ends, you must pay all outstanding wages and entitlements within 14 days of the termination date. If you miss that deadline, a 20% annual default interest rate applies to the unpaid amount. That’s a significant cost, so final payroll processing on termination needs to be treated as a hard deadline.
Mandatory contributions
South Korea operates four mandatory social insurance schemes. Each has its own rate, ceiling, and remittance rules. As the employer, you withhold the employee’s share from gross pay and remit it together with your own contribution.
National pension
The National Pension contribution rate is 9.5% of the employee’s monthly salary, split evenly at 4.75% each for employer and employee. There’s a monthly salary ceiling of KRW 6,370,000, which means contributions are calculated on a maximum of that amount regardless of actual earnings. Contributions are due by the 10th of the following month.
Health insurance and long-term care insurance
Health insurance contributions are approximately 4.004% of monthly salary for both employer and employee. Long-Term Care Insurance is calculated as a percentage of the health insurance premium rather than salary directly. Together, these two form the bulk of the health-related payroll cost for most employers.
Employment insurance
Employment Insurance rates differ by employer size and industry. As the employer, you’ll pay between 1.15% and 1.75% of the employee’s salary. The employee contributes 0.90%. Rates at the higher end of the employer range apply to larger firms, so your specific rate will depend on your headcount.
Workers’ compensation insurance
Workers’ Compensation Insurance is an employer-only cost, ranging from 0.56% to 18.56% depending on the industry and its associated risk level. A desk-based software team will sit at the lower end; higher-risk industries attract significantly higher rates. Your rate is assessed when you register your business with the relevant authority.
Income tax and the year-end settlement
Income tax in South Korea is progressive, running from 6% to 45% across six brackets. A 10% local income surtax applies on top of the national rate, so the effective top marginal rate for high earners is 49.5%.
As the employer, you withhold income tax from each monthly pay run and remit it to the National Tax Service. This isn’t a final settlement though. It’s a provisional withholding based on estimated annual liability.
Year-end settlement (연말정산)
Each February, you carry out the year-end settlement process, known in Korean as 연말정산. This is a full reconciliation of each employee’s actual annual tax liability against what was withheld across the year. You gather deduction documentation from each employee, recalculate the correct tax for the year, and either refund the overpayment or collect the shortfall through the February payroll.
The year-end settlement process is a significant administrative exercise. Employees submit evidence for deductions covering medical expenses, education costs, charitable donations, and other allowable items. You’re responsible for processing those claims correctly and ensuring the reconciled figures are accurately reported to the National Tax Service.
Payroll records and compliance
Payslips are mandatory in South Korea and must be issued in Korean. Each payslip needs to itemise all components of pay and all deductions, including each social insurance contribution line and the income tax withheld. A payslip that doesn’t clearly break down deductions isn’t compliant.
You’re required to maintain accurate payroll records and keep documentation that supports your social insurance filings and tax remittances. Hiring must be formally reported, and your employment contracts need to be registered with the relevant authorities. Audits from the National Tax Service or the Ministry of Employment and Labour can require you to produce records going back several years, so documentation hygiene matters from day one.
How an EOR handles korean payroll
Running payroll in South Korea directly requires a locally registered entity. Without one, you have no standing to remit social insurance contributions, withhold income tax, or enter into employment contracts that Korean law recognises. That’s a significant barrier if you’re testing the market or hiring a small number of people.
An Employer of Record (EOR) removes that barrier. The EOR acts as the legal employer in South Korea, handling every element of payroll compliance on your behalf. That includes monthly contribution remittances, income tax withholding, payslip issuance in Korean, and the year-end settlement process each February.
If you want to understand the model in more detail before committing, the guide to what is an Employer of Record (EOR) walks through how it works in practice. For a comparison of providers, see the roundup of EOR services.
Getting started
South Korean payroll isn’t complicated once you understand the structure, but it does require precision. The combination of four social insurance schemes, monthly withholding, and an annual reconciliation leaves little margin for error. Every deadline missed or deduction miscalculated creates downstream liability.
RemotePass handles compliant payroll for South Korea hires, including all social insurance contributions, tax remittances, Korean-language payslips, and year-end settlement. Book a RemotePass demo to see how it works for your team.
