Korea's four major social insurances and its severance pay (retirement allowance) system are the features most likely to catch out first-time entrants. Companies typically use an Employer of Record for fast, compliant entry, payroll management once a Korean entity exists, and entity setup for firms building lasting local presence.

Employer of Record in South Korea

An EOR allows a company to hire in Korea without registering for the four major social insurances or navigating the statutory retirement allowance (severance) system that applies to virtually all employees after one year of service. It suits companies making early hires, testing the Korean market, or hiring specialist talent while a longer-term entity decision is pending. It is less suited to companies with an existing Korean entity or planning larger, long-term teams where direct benefit and severance fund management is expected.

How payroll works in South Korea

Korean payroll withholds income tax (with a small additional local income tax) and requires contributions to four major social insurances: National Pension, National Health Insurance (plus long-term care insurance), Employment Insurance, and Industrial Accident Compensation Insurance, split between employer and employee (Industrial Accident Insurance is employer-only). Payroll is monthly, and a statutory retirement allowance (severance pay), broadly equivalent to one month's average wage per year of service, must be accrued or funded through a retirement pension scheme for virtually every employee with over a year of tenure.

Payroll frequency and reporting obligations

Monthly payroll is standard, with income tax and the four social insurances remitted monthly to the respective authorities. Annual year-end tax settlement reconciles most employees' tax position through the employer. Employers must register each employee with the National Pension Service, National Health Insurance Service, and Employment/Industrial Accident Insurance authorities at the start of employment, and retirement allowance obligations must be tracked as an ongoing accrued liability or funded through a Defined Benefit or Defined Contribution retirement pension plan.

Key payroll nuances

Statutory retirement allowance (severance) is one of the most consequential Korean payroll features: employees with at least one year of continuous service are entitled to an amount roughly equal to 30 days' average wage per year of service, payable on termination or resignation, and employers increasingly fund this through a registered retirement pension scheme rather than a simple internal accrual. There is no separate 13th-month mandate, but many Korean employers pay bonuses tied to company or individual performance as standard practice. Working hours are capped at 52 hours per week (including overtime) under labour law reforms, and overtime pay premiums are statutorily mandated.

Pay components and employer costs

Typical pay components include base salary, performance-linked bonus where offered, and meal or transport allowances common in many companies. Employer costs beyond salary include the employer share of the four social insurances and the ongoing retirement allowance accrual or pension funding obligation, which together commonly add 15 to 20 percent for the insurances alone, with retirement allowance funding adding a further significant cost that needs separate budgeting given its size relative to salary.

Benefits and leave entitlements

Statutory annual leave starts at 15 days after one year of service, with additional days accruing for every two years of continuous service up to a capped maximum. Maternity leave is a statutory 90-day entitlement (120 days for multiple births), with paternal leave and reduced working hour options for childcare also available under family-friendly labour policy. Public holidays follow both the national and, for many, the lunar calendar (such as Korean New Year and Chuseok), which shift dates annually. National Health Insurance provides Korea's core universal healthcare coverage.

Hiring and employment contracts

Written employment contracts specifying wage, working hours, and holidays are a legal requirement, and failure to provide one in writing exposes the employer to penalties. Probation periods are commonly three months, contract-defined, and during this period reduced protections against termination may apply, though this varies. Fixed-term contracts are capped at two years in total before the employee generally gains rights akin to indefinite employment. Termination of regular employees without just cause is difficult under Korean labour law, and severance/retirement allowance obligations apply regardless of the reason for separation once the one-year service threshold is met.

Entity setup in South Korea

A Korean subsidiary (usually a chusik hoesa, similar to a corporation, or yuhan hoesa, similar to an LLC) is the standard vehicle, requiring registration with the local court registry, a foreign investment notification with KOTRA or relevant bank, and a minimum capital injection. Post-incorporation, the entity registers for business licence, tax, and the four social insurances before hiring. End-to-end setup typically takes six to ten weeks, including capital injection and bank account opening.
