Corporate & Business/Legal Q&A

Do You Need a Korean Entity to Do Business in Korea?

Short Answer

Not always. A foreign company may carry out limited activities in Korea without forming a Korean entity.
However, once the activities go beyond preparatory or auxiliary functions and start to constitute a business presence in Korea, the company may face Korean corporate registration and tax issues (e.g., permanent establishment (PE) exposure and VAT considerations).


Can a Foreign Company Operate in Korea Without a Local Entity?

Yes, in limited circumstances. A foreign company may engage in non-commercial or preparatory activities in Korea without establishing a local entity.

These may include:

  • Market research
  • Business meetings and negotiations
  • Coordination with local partners
  • Preliminary business development

From a tax perspective, such activities may avoid creating a taxable presence (i.e., a permanent establishment) if they remain preparatory or auxiliary in nature.


When Is a Korean Entity Required?

A Korean entity or branch is not automatically required simply because revenue is generated.

However, if a foreign company is carrying on business in Korea or continuing transactions in Korea, it may need to establish a branch or other appropriate structure and complete the required registrations.

From a tax perspective:

  • If the company has a fixed place in Korea through which it carries out core and significant business activities, it may be treated as having a permanent establishment (PE)
  • By contrast, a place used only for activities such as advertising, information gathering, or market research may fall within the preparatory or auxiliary exception

What Are the Main Options for Foreign Companies?

Foreign companies typically consider the following structures when entering Korea:

Liaison Office (Representative Office)

  • Non-commercial or auxiliary activities only
  • Not intended for revenue-generating business
  • Established as a local office of the foreign 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

The appropriate structure depends on the company’s business model and long-term plans.


Are There Risks in Operating Without a Local Entity?

Yes. Operating in Korea without an appropriate structure may create legal and tax risks.

Potential issues include:

  • Being treated as having a business presence (PE) in Korea
  • Exposure to Korean corporate tax or VAT depending on the nature of activities
  • Regulatory issues if activities amount to carrying on business in Korea
  • Practical difficulties in enforcing contracts or collecting payments

For these reasons, the scope and nature of activities should be carefully reviewed.


Is This Relevant for Cities Like Busan?

Yes. Foreign companies entering cities such as Busan often begin with limited activities before establishing a formal presence.

However, once business activities expand to revenue-generating operations or ongoing transactions, legal and tax considerations become more significant regardless of location.


Practical Considerations for Foreign Companies

Before deciding on a structure, foreign companies should consider:

  • Whether their activities may constitute carrying on business in Korea
  • The nature of customer relationships and transactions
  • Tax implications, including potential PE exposure
  • Long-term business plans in Korea

A clear understanding of these factors is essential to selecting the appropriate entry structure.


Conclusion

A foreign company does not always need a Korean entity to begin operating in Korea.
However, once activities go beyond preparatory or auxiliary functions or develop into ongoing business operations, appropriate legal structuring becomes increasingly important to manage regulatory and tax risks.
