Korea – Written Employment Contract Requirement: Statutory Content and Delivery Timing
South Korean law requires employers to provide every employee with a written employment contract at the time of hiring, stating key terms of employment. Article 17 of the Labor Standards Act (근로기준법) imposes this obligation regardless of the formality or industry of employment: “The employer shall prepare and provide to the employee a document specifying the terms and conditions of employment.”
Mandatory contract content: The written contract must, at minimum, specify working hours, wage calculation and payment date, paid holidays, annual leave, and grounds for termination. Article 17(2) and Article 93 of the Act enumerate the minimum required disclosures and any work rules that must be clearly stated in writing.
Timing and delivery: The document must be issued immediately upon the commencement of work. The law does not permit oral-only contracts or delayed delivery. Since 2021, written employment contracts may also be delivered electronically (e.g., by PDF or secure messaging platform) if the employee consents. Failure to provide a proper written contract can result in fines up to KRW 5 million under Article 114.
Language: There is no statutory requirement to provide the contract in a foreign language, but for foreign workers, best practice is to provide an accurate Korean-language version accompanied by a translation.
This written contract requirement applies to all employees, including non-permanent and part-time workers, except in very limited exclusions for certain family and agricultural workers.

South Korea — Employer Payroll Income Tax Withholding and Remittance Obligations
Employers in South Korea are legally required to calculate, withhold, and remit payroll income tax (근로소득 원천징수) and local inhabitant (local income) tax on all employee wages, under the Income Tax Act (소득세법) and Local Tax Act (지방세법).
Scope and Trigger Under Article 145 of the Income Tax Act, any employer paying wages or salary to employees must withhold income tax at the source every pay period. The withholding tables and calculation methods are set by the Ministry of Economy and Finance under the Enforcement Rule of the Income Tax Act. There is no explicit carve-out by company size or ownership; exceptions are only as enumerated by law.
Withholding and Payment Deadlines
- National payroll (income) tax withheld from employees' wages must be paid to the National Tax Service (NTS) by the 10th of the month following payment (Income Tax Act, Art. 145(1)).
- Additionally, the employer must withhold and remit local inhabitant tax, calculated as 10% of the national income tax amount withheld, to the relevant local government by the same deadline (Local Tax Act, Art. 103-17).
Monthly and Annual Returns Employers are obligated to file a monthly withholding tax report (원천징수이행상황신고서), specifying the wage amounts and tax withheld and remitted (Income Tax Act, Art. 145(7)). There is also a statutory annual settlement (“year-end tax adjustment” or 연말정산) requirement: employers recalculate tax liability for each employee at the year’s end based on actual income, credits, and deductions, and must make necessary adjustments, typically in the February payroll of the following year (Income Tax Act, Art. 137(1)-(3)).
Penalties for Non-Compliance Failure to withhold or remit employee payroll taxes on schedule exposes the employer to penalties and surcharges as set forth under the National Tax Collection Act (국세징수법). Unable to confirm as of 2026-07-11.

Korea — Foreign Employer Entity Requirements: Must You Register a Local Corporation to Hire Staff?
A foreign company seeking to hire employees in South Korea generally must establish a registered presence in the country to lawfully run payroll, withhold taxes, and enroll staff in statutory social insurance. Articles 3 and 4 of the Business Registration Act (사업자등록법) require any person or entity conducting business with a place of business in Korea—including the employment of local staff—to obtain a business registration number (사업자등록번호) from the National Tax Service (NTS). The official NTS position is that registration as a business (corporation, branch, or similar) is prerequisite to employer enrollment in health, pension, employment insurance, and payroll tax withholding schemes. However, neither the Act nor published regulations state outright that an unregistered foreign entity is categorically barred from all payroll acts—this is the practical outcome under NTS and insurance agency procedures.
Branch or Subsidiary Options: Foreign employers commonly:
- Incorporate a wholly-owned Korean company (주식회사, chusik hoesa), which is an independent legal entity;
- Register a branch office (지점, jijŏm) as a foreign company under the Supreme Court Registry, which then obtains business registration from the NTS;
- Establish a liaison office (연락사무소, yeollak samuso) for non-revenue functions—by MOJ and Supreme Court guidelines, liaison offices may not carry out direct revenue activity or act as legal employer for local staff (not an explicit statutory bar, but a regulatory one; not exhaustive).
Employer-of-Record (EOR) Arrangements: Market practice in Korea allows use of local EORs that hire employees directly and second them to the foreign company. Statutes do not expressly govern or prohibit these arrangements. In this case, the EOR is the statutory employer, responsible for payroll and compliance, but the foreign company may still face Korean permanent establishment (PE) risk for tax if its activities in Korea trigger Corporate Tax Act Articles 94–96.
Permanent Establishment (PE) Triggers: The Corporate Tax Act defines PE to include a fixed place of business (Art. 94), an agent habitually concluding contracts on behalf of the foreign enterprise (Art. 95), or certain service/permanent activity thresholds (Art. 96). Factual determinations are made in accordance with domestic law and relevant tax treaties, and case-specific factors apply.
Where Korean law or guidance is silent or practice-based (EOR, payroll agency), this is so stated above.

South Korea — Statutory Minimum Wage and Maximum Working Hours (2024 thresholds and Labor Standards Act requirements)
Statutory Minimum Wage South Korea sets a national statutory minimum wage each year. For 2024, the statutory minimum wage is KRW 9,860 per hour. This rate applies to all employees covered by the Labor Standards Act (근로기준법), regardless of employment status (full-time, part-time, temporary) or industry—subject only to narrowly-defined exclusions for family or home-based workers under the Minimum Wage Act (최저임금법) Article 6. The new minimum wage is promulgated annually by presidential decree, with the 2024 rate effective from 1 January 2024 through 31 December 2024 (Minimum Wage Act Article 10; Presidential Decree No. 33221).
Legal Working Hours The Labor Standards Act (근로기준법) Article 50 caps regular working hours at 40 hours per week (8 hours per day, exclusive of breaks). Overtime may be authorized, but total working hours (regular plus overtime) must not exceed 52 hours per week (Labor Standards Act Article 53 as amended). Employees may work up to 12 hours of overtime per week if there is written agreement between employer and employee, with the overtime premium at not less than 150% of ordinary wages (Labor Standards Act Art. 56).
Breaks For every four hours worked, employees must be granted at least 30 minutes of rest; for every eight hours, at least one hour (Labor Standards Act Article 54). Break schedules must be determined by employer and employee but are not included in working hours.
Practical Traps Employers must update payroll systems annually to ensure compliance with the new minimum wage. Violations may result in fines and retroactive payments. The 52-hour weekly working hour limit is rigorously enforced and is a standard audit trigger on labor inspections. Some categories (e.g., managers/supervisors, certain construction or transport workers) are exempted according to Ministry of Employment and Labor enforcement guidelines (Labor Standards Act Articles 63 and 59), but exclusions are narrowly interpreted.
