A branch office is a foreign company that establishes its presence in Thailand. Branch offices are allowed to engage in trading activities and are allowed to earn income in Thailand. Under the Thai law, the Foreign Business Act B.E. 2542 governs the Branch Offices (FBA). Subsequently the Branch Office that carries out activities under one of the categories of the FBA is required to apply for a Foreign Business License. The chance of approval increases if the business is unique, does not compete with Thai businesses, or involves dealings among members of an affiliated company. Since the branch office is considered an extension of its head office it does not have shareholders or directors. The parent company must appoint a branch office manager to lead operations in Thailand.

Therefore, the parent company retains legal liability for contracts, and for tortious acts done. A branch is subject to Thai corporate income tax at the regular 30% on profit derived from its business operations in Thailand. It is important to clarify beforehand that Thai Tax Authorities may consider taxable income also the income earned in Thailand by the foreign Head office. The paid-up capital requirement is set at a minimum of 3 Million Baht.
