    Step-by-Step Process

    1

    Choose Your Business Structure

    Decision phase

    The most common structure for foreigners is a Thai Limited Company (บริษัทจำกัด). Alternatives include BOI-promoted company (allows 100% foreign ownership), branch office, or representative office.

    Tips

    • Thai Ltd: requires minimum 2 shareholders (reduced from 3 by Civil and Commercial Code Amendment Act No. 23 B.E. 2566 (2023), effective 7 February 2023), 51% Thai-owned (unless BOI/FBA)
    • BOI: 100% foreign ownership possible, tax incentives, but requires promoted activity
    • Branch office: extension of foreign company, limited to approved activities

    Reserve Company Name

    1-3 days

    Submit 3 name choices to the Department of Business Development (DBD). The name must be unique and not misleading.
