Successfully Set Up a Branch Office in Korea: The Ultimate Guide 2025

The procedure to set up a branch office in Korea, including steps like application submission, approval process, and legal compliance, applicable to liaison offices in Korea as well.

Set up a branch office in Korea or establish a liaison office to expand your business into one of Asia’s most vibrant markets. Both options provide unique opportunities to establish a corporate presence, but they differ in purpose, requirements, and tax implications. This guide covers everything you need to know about setting up either a branch or liaison office in South Korea.

What is a Branch Office in Korea?

A branch office in Korea allows foreign companies to conduct profit-generating activities such as sales and business operations. Under the Foreign Exchange Transactions Act, branch offices must undergo a formal registration process and are treated as permanent establishments under Korean tax laws.

Key Features of a Branch Office:

  • Activities: Engages in revenue-generating operations.
  • Legal Registration: Requires court and business registration.
  • Taxation: Profits generated in Korea are subject to corporate tax rates, ranging from 10% to 22%.

What is a Liaison Office in Korea?

A liaison office in Korea, on the other hand, is restricted to non-sales activities. It serves as a representative of the head office and focuses on tasks like market research, R&D, and quality control. Liaison offices do not require court registration but must obtain a business code from the local tax office.

Key Features of a Liaison Office:

  • Activities: Limited to non-sales functions such as business contacts, market research, and advertisements.
  • Legal Registration: No court registration required; instead, a tax identification number is issued.
  • Taxation: Liaison offices are not subject to corporate tax as they do not generate profit in Korea.

Steps to Set Up a Branch Office in Korea

Establishing a branch office requires compliance with the Foreign Exchange Transactions Act. Below is the process:

  1. Submit Application: Report the establishment of a branch to a foreign exchange bank.
  2. Approval: The application is reviewed by the bank and the Ministry of Strategy and Finance. Approval typically takes one week.
  3. Registration: For branch offices, court and business registration are required.
  4. Compliance: Complete relevant administrative procedures in line with Korean laws.

Required Documents for Branch Office Registration

When setting up a branch office in Korea, you’ll need the following:

  1. A completed application form for branch establishment.
  2. Articles of incorporation (notarized in the country of the head office).
  3. Certificate of appointment for the branch representative, including a passport copy.
  4. Power of attorney for delegated tasks (notarized).
  5. A certified copy of corporate registration or relevant permits (notarized).
  6. A resolution from the board of directors approving the branch establishment.

Steps to Establish a Liaison Office in Korea

The process for setting up a liaison office is more straightforward:

  1. Report the establishment of the liaison office to a foreign exchange bank.
  2. Notify the Ministry of Strategy and Finance for certain restricted business activities, such as financial or securities-related tasks.
  3. Obtain a unique business code from the local tax office.

Since liaison offices are not engaged in sales, their establishment process is less complex than that of branch offices.
