Korea, Republic of

A corporation having its head office or principal office in Korea is a resident corporation. A corporation with a place of effective management in Korea is also treated as a resident corporation.

Permanent establishment (PE)

The term 'permanent establishment' is defined as any fixed place of business in Korea where the business of a foreign entity is wholly or partly carried on.

The following places will trigger a PE of a foreign entity, among others:

• The place where the employee(s) of the foreign entity provides services in Korea for more than six months within 12 consecutive months.
• The place where the employee(s) of the foreign entity continuously or repeatedly renders similar services in Korea for two or more years, even if each service visit is for less than six months within 12 consecutive months.

Also, in the absence of a fixed place in Korea, if a foreign entity has a dependent agent in Korea (i) who has the authority to conclude contracts on its behalf and who has repeatedly exercised that authority or (ii) who, even if having no such authority, repeatedly performs a principal role in the course of concluding contracts, it will be deemed to have a PE in Korea.

Exceptions to a PE in Korea for a non-resident corporation are limited to specific places of business used only for preparatory or auxiliary nature, and such fixed places include purchasing or storage of goods not for sale, advertising, publicity, collecting or furnishing of information, etc. Even though the specific place where activities of preparatory or auxiliary nature are performed, it could be regarded as a PE in one of the following cases:

• A foreign entity or its foreign related party has a Korea PE at the same place where the specific place for preparatory or auxiliary activities exists or at a different place in Korea and the activities performed via the PE and the specific place are complementary to each other.
• Even if the foreign entity or its foreign related entity has no PE in Korea, the activities of the specific places exceed preparatory or auxiliary nature as a whole.
