South Korea is a strategic entry point for companies expanding into Asia. With a highly skilled workforce, advanced infrastructure, and strong regulatory framework, it offers significant opportunities for long-term growth.
One of the first and most important decisions foreign companies face is how to legally establish their presence in Korea. The two most common options are forming a Korean subsidiary or registering a branch office of the foreign parent company.
While both structures are permitted, they serve different strategic purposes. Choosing the right one early can reduce risk, improve credibility, and support future expansion.
A Korean subsidiary is incorporated as a separate legal entity under Korean law, usually as a limited liability company (Yuhan Hoesa) or a joint-stock company (Chusik Hoesa). It can sign contracts, hire employees, and hold assets in its own name.
A branch office, on the other hand, is not legally separate from the foreign parent company. All rights, obligations, and liabilities incurred in Korea belong directly to headquarters.
At a glance:
Subsidiaries benefit from greater operational freedom. Their permitted activities are defined in their articles of incorporation and can be expanded over time to reflect changing commercial needs.
Branch offices are more restrictive. They must operate strictly within the existing business scope of the foreign parent company and cannot independently broaden their activities in Korea.
Typical use cases:
From a risk management perspective, the difference between the two structures is significant.
A subsidiary generally limits liability to the Korean entity itself, providing a degree of protection to the parent company (subject to guarantees or exceptional circumstances).
A branch office provides no such separation. Any legal, contractual, or regulatory issues in Korea directly affect the foreign parent company.
Risk considerations:
Subsidiaries are taxed in Korea as resident corporations on locally generated income and must comply with Korean accounting, tax filing, and audit requirements. Depending on structure, they may also qualify for Foreign Direct Investment (FDI) incentives.
Branch offices are taxed only on Korean-source income, but profits and losses are attributed to the parent company. While compliance requirements may be lighter, branches are still subject to Korean tax reporting and audits.
Companies should consider how each structure affects both local compliance and group-level tax planning.
In Korea, legal structure influences credibility. Subsidiaries are often viewed as a sign of long-term commitment, which can support banking relationships, partnerships, and talent acquisition.
Branch offices are fully legitimate but may be perceived as temporary or limited in scope. This perception can impact recruitment and commercial negotiations, particularly at senior levels.
For companies planning to scale, market perception is an important strategic factor.
In most cases:
The optimal choice depends on strategy, risk tolerance, and future expansion plans—not just speed or cost.
Choosing between a subsidiary and a branch office in South Korea is a strategic decision that shapes risk exposure, market credibility, and scalability. Aligning the legal structure with commercial objectives from the start helps foreign companies enter the Korean market with clarity and confidence.

Early legal and tax structuring can prevent costly changes later. Speak with an advisor before committing to a structure.
