What Is a Liaison Office in Korea and What Can It Do?

Short Answer

A liaison office in Korea is a limited, non-revenue presence typically used for preparatory or auxiliary activities, such as market research, communications, promotional support, and coordination with the foreign head office.

Unlike a branch office or Korean subsidiary, a liaison office generally should not conduct direct sales, issue invoices, receive payments, or provide revenue-generating services in Korea.

If the company plans to generate revenue, sign contracts locally, hire an operational team, or pursue FDI and foreign-invested company registration, a branch office or Korean subsidiary should be reviewed instead.

Why Foreign Companies Consider a Liaison Office in Korea

Foreign companies often consider a Korean liaison office when they want to explore the Korean market before committing to a full business structure.

A liaison office may be useful where the foreign company wants to:

• conduct market research;
• communicate with potential customers or partners;
• collect business information;
• support advertising or promotional activities;
• coordinate with the foreign head office;
• monitor local trends; or
• prepare for possible future investment in Korea.

This structure can be attractive because it may be simpler than incorporating a Korean subsidiary or registering a branch office. However, the scope of activities must be carefully managed.

What Can a Liaison Office Do in Korea?

A liaison office is generally used for non-revenue, preparatory, or auxiliary activities.

Typical activities may include market research, business communication, collecting information, promoting the foreign company, coordinating meetings, and supporting communication between the foreign head office and Korean contacts.

In simple terms, a liaison office may help the foreign company understand the Korean market, but it should not operate as a full business entity.

The exact scope should be reviewed based on the company’s actual activities, because a liaison office that performs revenue-generating work may create legal, tax, or registration issues.

What Should a Liaison Office Generally Avoid Doing?

A liaison office is typically not intended to conduct ordinary business operations in Korea.

In practice, a liaison office should be careful about activities such as:

• directly selling products or services;
• issuing invoices in Korea;
• receiving payments from Korean customers;
• entering into revenue-generating contracts;
• performing paid services;
• operating a store or sales office;
• managing inventory for sale; or
• conducting licensed or regulated business activities.

If the office will generate revenue or operate commercially, a branch office or Korean subsidiary should be considered.

Liaison Office vs. Branch Office: What Is the Difference?

The key difference is whether the office conducts revenue-generating business.

A liaison office is generally limited to non-revenue activities. It is mainly used for market research, communication, and support functions.

A branch office in Korea, by contrast, may generally conduct business activities on behalf of the foreign parent company. A branch office can be more appropriate where the foreign company intends to conduct sales, provide services, sign contracts, or generate revenue in Korea.

However, a branch office is still not a separate Korean legal entity. It remains an extension of the foreign parent company.

---

Liaison Office vs. Korean Subsidiary: What Is the Difference?

A Korean subsidiary is a separate legal entity incorporated in Korea.

Unlike a liaison office, a subsidiary may conduct ordinary business activities, enter into contracts under its own name, hire employees, issue invoices, receive revenue, and operate as a Korean company.

A subsidiary may be more appropriate where the foreign company wants to:

• operate a full business in Korea;
• separate Korean business liabilities from the parent company;
• bring in Korean or foreign investors;
• establish a joint venture;
• register as a foreign-invested company;
• pursue investment-based business planning; or
• build a long-term Korean operation.

A liaison office may be useful for early-stage exploration, but it is usually not enough for full commercial operations.

---

Does a Liaison Office Need Corporate Registration?

A liaison office does not operate in the same way as a Korean subsidiary or branch office.

Unlike a branch office, which may involve court registry registration, or a Korean subsidiary, which requires incorporation and corporate registration, a liaison office is typically set up through a more limited registration or reporting process depending on the planned activities.

Also, FDI and foreign-invested company registration generally apply to establishing or investing in a Korean subsidiary, rather than setting up a liaison office.

However, a liaison office may still require practical setup steps, such as preparing parent company documents, securing an office address, appointing a local contact person, completing tax-related registration where applicable, and opening a bank account for operating expenses.

The exact process should be reviewed based on the foreign company’s jurisdiction, planned activities, office setup, and bank requirements.

---

Can a Liaison Office Hire Employees in Korea?

Potentially, yes.

A liaison office may need local staff to conduct market research, communication, administrative work, and business coordination.

However, if the liaison office hires employees in Korea, it should comply with Korean employment law, payroll obligations, social insurance requirements, tax withholding, and workplace compliance rules.

Foreign companies should also make sure that employees of the liaison office do not engage in activities beyond the permitted scope of the liaison office, such as direct sales, contract execution, or paid service delivery.

---

Can a Liaison Office Open a Bank Account in Korea?

In practice, a liaison office may need a Korean bank account to pay office rent, employee salaries, administrative expenses, and local operating costs.

However, bank account opening can be a practical challenge. Korean banks may request documents regarding the foreign parent company, representative authority, office purpose, source of funds, and planned activities in Korea.

Because a liaison office is generally intended for non-revenue activities, its bank account should usually be used for operating expenses funded by the foreign head office, rather than for receiving business revenue from Korean customers.

---

What Are the Tax and Accounting Issues for a Liaison Office?

A liaison office is generally intended for non-revenue activities, so its tax position may differ from a branch office or subsidiary.

However, if the liaison office’s activities go beyond preparatory or auxiliary functions and become actual business operations, tax and regulatory issues may arise.

This is especially important if the office is involved in sales, contract negotiation, customer management, service delivery, or revenue-related activity.

Foreign companies should obtain separate tax and accounting advice if there is any possibility that the liaison office’s activities may create taxable business presence or permanent establishment issues in Korea.

---

When Is a Liaison Office a Good Option?

A liaison office may be a good option where the foreign company wants a limited, low-commitment presence in Korea before launching full operations.

It may be suitable where the company wants to:

• research the Korean market;
• identify potential customers or partners;
• support communication with Korean contacts;
• study regulatory or licensing issues;
• prepare for future incorporation;
• coordinate with local consultants or advisors; or
• test business opportunities before committing to a branch or subsidiary.

However, the company should carefully monitor the actual activities of the liaison office to ensure that it does not operate like a revenue-generating business.

---

When Should a Foreign Company Choose a Branch or Subsidiary Instead?

A foreign company should consider a branch office or Korean subsidiary instead if it intends to conduct active business operations in Korea.

This may be the case where the company plans to:

• sign contracts with Korean customers;
• issue invoices or receive payments;
• sell products or services;
• provide paid services in Korea;
• hire a larger operational team;
• obtain business licenses;
• establish a joint venture;
• register as a foreign-invested company; or
• build a long-term Korean business.

In these situations, a liaison office may be too limited. Choosing the wrong structure can create legal, tax, banking, and regulatory problems later.

What Should Foreign Companies Check Before Setting Up a Liaison Office?

Before setting up a liaison office in Korea, foreign companies should review:

• the purpose of the Korea office;
• whether activities will be revenue-generating;
• whether contracts will be signed in Korea;
• whether Korean customers will make payments;
• whether employees will be hired locally;
• whether any regulated industry issues apply;
• whether a branch or subsidiary would be more appropriate;
• bank account opening requirements; and
• tax and accounting implications.

The key question is whether the Korea office will only support the foreign head office or whether it will actually conduct business in Korea.

---

What Is a Practical Order of Work?

A practical order of work may be:

• confirm the Korea market entry plan;
• decide whether the office will conduct revenue activities;
• compare liaison office, branch office, and subsidiary options;
• check tax and regulatory implications;
• prepare parent company documents;
• secure a Korean office address;
• appoint a local representative or contact person;
• complete necessary registration or setup steps;
• open a bank account if needed; and
• prepare employment and internal compliance documents.

This sequence helps avoid setting up a liaison office first and later discovering that the planned activities require a branch, subsidiary, license, or different tax treatment.

Practical Considerations for Foreign Companies

Foreign companies should not choose a liaison office only because it appears simpler.

A liaison office can be useful for early-stage market research and communication, but it has important limitations. If the company’s Korea office will engage in sales, contracting, revenue generation, or regulated business operations, the company should carefully review whether a branch office or Korean subsidiary is required.

The company should also train local staff on the permitted scope of activities. In practice, problems may arise when a liaison office gradually begins to perform sales, customer management, or service delivery functions without changing its legal structure.

---

Conclusion

A liaison office in Korea can be a practical first step for foreign companies that want a low-commitment presence in Korea for non-revenue activities, such as market research, communications, and promotional support.

However, the company should continuously monitor the office’s actual activities to avoid inadvertently creating revenue-generating operations, tax exposure, or compliance issues.

Where commercial operations are intended, a branch office or Korean subsidiary structure, together with related registration, licensing, tax, and banking requirements, should be reviewed in advance.
