“Can’t we just start with any structure and change it later?”
This is one of the most common questions we receive from foreign companies considering entry into the Korean market. However, choosing the wrong structure at the outset can expose the foreign headquarters to unexpected liabilities or potentially significant tax consequences.
Changing the structure later is also far from simple. There is no automatic legal procedure for converting a representative office into a subsidiary. In many cases, changing the structure requires closing the existing office, terminating or transferring employees, transferring assets and contracts, and establishing a new entity from the beginning. This can result in substantial additional costs, delays, and administrative burdens.
A decision made too quickly at the market-entry stage can therefore create significant problems as the Korean business grows. Based on our experience advising numerous foreign companies entering Korea, this guide explains how to select the structure that best fits your business model.

1. Comparison: Subsidiary, Branch, and Representative Office
| Category | Subsidiary | Branch | Representative Office |
|---|---|---|---|
| Legal Status | Separate and independent Korean legal entity | Part of the foreign headquarters; same legal entity | Part of the foreign headquarters; same legal entity |
| Principal Regulatory Framework | Foreign Investment Promotion Act | Foreign Exchange Transactions Act | Foreign Exchange Transactions Act |
| Commercial Activities | Generally permitted | Revenue-generating business permitted | Limited to non-commercial activities |
| Legal Liability | Generally limited to the subsidiary | Liability may extend directly to the foreign headquarters | Liability may extend directly to the foreign headquarters |
| Taxation | Subject to Korean corporate taxation | Generally taxed on Korean-source income attributable to the branch | Generally not subject to corporate income tax if no taxable business activities are conducted |
Liability of the Foreign Headquarters
Subsidiary:
A subsidiary is a separate legal entity incorporated in Korea. As a general rule, if the Korean subsidiary incurs debts or becomes involved in litigation, the foreign parent company’s liability is limited to its investment in the subsidiary. The parent company’s assets are therefore generally insulated from liabilities incurred by the Korean subsidiary.
Branch / Representative Office:
A branch or representative office is not a separate legal entity. Rather, it is legally part of the foreign headquarters operating in Korea. Accordingly, liabilities arising from the Korean operation—including contractual debts, employment-related claims, and damages—may directly extend to the foreign headquarters.
Commercial Activities
Subsidiary / Branch:
Both structures may conduct commercial activities in Korea, enter into contracts with customers, generate revenue, and earn profits.
Representative Office:
A representative office is limited to preparatory and auxiliary activities, such as market research, R&D, liaison activities, and promotion of the foreign headquarters. It cannot independently conduct revenue-generating business in Korea. Engaging in activities such as executing sales contracts with Korean customers or receiving payments may give rise to issues under Korean foreign exchange and tax laws.
2. Guide to Choosing the Right Business Structure
Subsidiary
Recommended for:
Companies planning to conduct continuous and substantial business operations in Korea, particularly those contemplating significant investment or long-term expansion.
Why choose a subsidiary?
Because the Korean subsidiary is legally and financially separate from its foreign parent company, liabilities arising from Korean operations generally remain at the subsidiary level rather than extending directly to the parent company.
A subsidiary may also provide greater credibility when conducting local banking transactions, participating in government support programs, hiring employees, and entering into B2B contracts with major Korean companies.
Typical examples: Manufacturing, distribution, IT platforms, and large-scale service businesses where liability management and long-term operations are important.
Branch
Recommended for:
Companies seeking to commence revenue-generating activities in Korea relatively quickly while maintaining strong control from the foreign headquarters and avoiding the capital structure associated with establishing a separate subsidiary.
Why choose a branch?
A branch can conduct commercial activities and generate revenue in Korea without establishing a separate legal entity. Its establishment process may be simpler than incorporating a subsidiary, and transferring operational funds between the headquarters and the Korean branch may also be relatively straightforward.
The key disadvantage, however, is that liabilities incurred by the Korean branch may directly expose the foreign headquarters.
Typical examples: Companies conducting short-term projects in Korea and service or consulting businesses that wish to maintain a headquarters-centered corporate structure.
Representative Office
Recommended for:
Companies that wish to explore the Korean market before commencing full-scale operations or that intend to conduct only non-commercial activities such as market research, R&D, liaison, or promotional activities.
Why choose a representative office?
Because a representative office cannot engage in revenue-generating business, its tax and administrative obligations are generally more limited than those of a subsidiary or branch.
It can therefore be an efficient structure for conducting market research, communicating with headquarters, carrying out promotional activities, and performing certain preparatory or R&D functions at relatively low cost.
Typical examples: Companies in the preliminary market-research stage and foreign companies establishing an R&D, liaison, or promotional presence in Korea.

Choosing the Wrong Structure at the Beginning Can Be Costly
Choosing the wrong business structure at the initial stage of entering Korea can ultimately require the closure of the existing operation and the establishment of an entirely new entity, resulting in unnecessary costs, delays, and administrative burdens.
More importantly, an inappropriate structure can expose the foreign headquarters to direct liability for Korean operations or create significant tax and regulatory risks.
Given the interaction between Korea’s foreign investment regulations, foreign exchange rules, corporate law, tax requirements, employment regulations, and establishment procedures, foreign companies should carefully determine whether a subsidiary, branch, or representative office best fits their intended activities before commencing operations in Korea.
