The Foreign Business Act (FBA) is one of the most important laws for foreigners wanting to invest or operate a business in Thailand. It defines which business activities are restricted or prohibited to foreign ownership. The law categorizes businesses into three lists:
- List 1: Businesses that are completely prohibited to foreigners (e.g., farming, forestry, and land trading).
- List 2: Businesses allowed only if special permission is granted by the Cabinet (e.g., certain industries impacting national security or culture).
- List 3: Businesses allowed if a Foreign Business License (FBL) is obtained (e.g., construction, advertising, and retail).
For many businesses, foreigners are limited to holding a maximum of 49% ownership, unless they obtain specific approvals or qualify for investment promotion.
