Overview: Foreign Entities in Korea – Legal Types & Key Tax Rules
Entering Korea as a foreign company involves choosing the correct entity form, complying with local registration, and navigating taxation. Common options include:
- Branch office (지사): extension of foreign entity; taxed on Korean‐source income; legal liability shared with parent.
- Subsidiary (자회사, typically a Korean stock or LLC equivalent): distinct legal person; taxed fully under Korean corporate tax laws.
- Representative office: limited to non‐commercial functions; no Korean corporate tax if it makes no profits.
Corporate Tax Rates & Withholding Tax
| Tax Type | Rate for Resident Corporation | Withholding Tax for Nonresidents |
|---|---|---|
| Corporate Income Tax | Progressive rates: ~10% up to KRW 200 million, 20% next bracket, 22% above some level + local surtax | -- |
| Withholding on Dividends / Interest / Royalties | -- | Usually around 15%; treaties may reduce rate |
| Capital Gains on Shares | Often taxed as business income; some exemptions for qualified holdings and treaty relief apply |
Note: Rates may vary depending on size, industry, and incentives offered by free economic zones.
VAT & Local Taxes
- Standard VAT rate in Korea is 10% on taxable supplies; foreign businesses are subject to VAT on supplies made within Korea.
- Local taxes may include registration taxes, property taxes, and others depending on your location and industry.
Compliance Essentials for Foreign Businesses
A. Establishing the Entity
- Register at Korean Commercial Registry. You’ll need a Korean representative, articles of incorporation in Korean, translation of foreign documents with authentication.
- Get a business registration certificate, open bank account, register for VAT & employer withholding if hiring staff.
B. Transfer Pricing & Related Party Transactions
- If doing intra‐company transactions (parent ↔ branch/subsidiary), Korea follows OECD TP guidelines. Ensure documentation of arm’s‐length pricing and consistent reporting.
C. Reporting & Audit / Tax Incentives
- Annual corporate income tax returns, quarterly VAT reports, withholding on employee wages and contractors.
- Investigate incentives: tax breaks in R&D, free trade zones, foreign investor zones; deductions for investment, job creation, etc.
Example: Foreign Tech SaaS Firm Expanding to Seoul
Suppose TechGlobal LLC, based in the US, wants to sell SaaS services in Korea. Key considerations:
- The company may set up a subsidiary to manage Korean sales, rather than a branch, to isolate liability and limit permanent establishment risk.
- Since services delivered electronically, ensure proper VAT registration—VAT is applied to services consumed within Korea even if delivered online.
- Transfer pricing rules apply between parent company (in the US) and Korean entity for support or platform fees. Document thoroughly.
- Withholding tax on any royalties or license fees paid abroad will need assessing under treaties—for example between Korea and the US.
Best Practices & Common Pitfalls
- Select entity form with worst and best situations in mind—subsidiary has higher setup cost but better separation; branch might be simpler but risk of unlimited liability.
- Know your sector‐specific incentives: foreign investment zones, manufacturing incentives, ICT or Green New Deal sectors receive favorable treatment.
- Be mindful of currency controls, cross‐border funds repatriation restrictions, and timing of recognizing revenue under Korean GAAP/IFRS.
- Maintain good local advisors—legal, tax, payroll, and compliance—to navigate ongoing obligations.
Bottom line: With careful structure, foreign businesses in Korea can thrive—paying the right taxes, not more, while accessing incentives. Planning ahead with local specialists is essential.
