A foreign company usually chooses one of three forms. A local corporation (subsidiary) is a Korean company registered under the Foreign Investment Promotion Act and may carry on any permitted business. A branch office is part of the foreign company and carries on the same business as its head office. A liaison office may not earn revenue and is limited to non-sales activities such as market research and business contacts. Branch and liaison offices are established under the Foreign Exchange Transactions Act.

Korea’s Income Inclusion Rule applies to fiscal years beginning from 1 January 2024; the Undertaxed Profits Rule follows from 1 January 2025. Check entity status and allocation rules before assuming a payment obligation.
The standard GloBE filing period is 15 months after year-end, extended to 18 months for the first applicable year. For a first in-scope year ending 31 December 2024, the deadline was 30 June 2026.
Korea has written the OECD extension into its law: the transitional safe harbour covers fiscal years beginning on or before 31 December 2027 and ending on or before 30 June 2029 (Enforcement Decree of the Adjustment of International Taxes Act, Art. 138, as amended February 2026). The election is made each year, and a jurisdiction that does not qualify in one year cannot use it in later years.
