What Is a Liaison Office in Korea? (Representative Office Explained)

Short Answer

A liaison office (also known as a representative office) in Korea is a local office established by a foreign company for non-commercial activities.
It is intended for preparatory or auxiliary functions and is generally not used for revenue-generating business activities in Korea.


What Is a Liaison Office?

A liaison office is a form of presence that allows a foreign company to operate in Korea without establishing a separate legal entity.

It is typically used for:

  • Market research
  • Business coordination with headquarters
  • Communication with local partners
  • Preliminary business development activities

In general, a liaison office is expected to perform non-business or auxiliary functions rather than core revenue-generating activities.


What Activities Are Not Allowed?

A liaison office in Korea is generally limited to non-commercial functions.

In particular:

  • If it signs sales contracts or conducts sales activities in Korea, it may be viewed as engaging in revenue-generating business, which can trigger tax or regulatory consequences
  • Issuing local tax invoices or booking local sales is typically inconsistent with the non-business nature of a liaison office and may indicate business operations in Korea

In certain regulated industries, specific laws may expressly prohibit particular activities by a liaison office.


How Is It Different from a Branch or Subsidiary?

Foreign companies entering Korea generally consider three structures:

Liaison Office (Representative Office)

  • Non-commercial or auxiliary activities
  • Not intended for revenue-generating business
  • Established as a local office of the foreign company without forming a separate Korean company

Branch Office

  • Can conduct business and generate revenue
  • Not a separate legal entity from the foreign company

Subsidiary (Korean Company)

  • Separate legal entity incorporated in Korea
  • Full business operations allowed

Choosing the appropriate structure depends on the company’s business objectives and level of commitment to the Korean market.


When Should a Liaison Office Be Used?

A liaison office is typically suitable when a foreign company:

  • Is exploring the Korean market before making an investment
  • Needs a local presence for communication and coordination
  • Does not yet intend to generate revenue in Korea

For example, companies entering cities such as Busan for initial market research or partnership discussions often consider this structure as a first step.


Key Limitations and Risks

While a liaison office is relatively simple to establish, it has important limitations:

  • Activities beyond preparatory or auxiliary functions may lead to classification as a business presence in Korea
  • This may result in tax exposure or regulatory obligations
  • It may not be suitable for long-term or revenue-generating operations

If the scope of activities expands, transitioning to a branch or subsidiary may become necessary.


Practical Considerations for Foreign Companies

Foreign companies should carefully evaluate:

  • The intended scope of activities in Korea
  • Whether revenue-generating activities are planned
  • Potential tax implications, including permanent establishment risks
  • The timeline for potential expansion into full operations

Selecting the wrong structure at the outset may lead to regulatory or tax issues.


Conclusion

A liaison office (representative office) in Korea is a useful option for foreign companies seeking a limited local presence without engaging in revenue-generating business activities.
However, if the company’s activities go beyond preparatory or auxiliary functions, it may trigger legal and tax consequences, making a different structure more appropriate.
