The Thailand Board of Investment (BOI) is a government agency under the Office of the Prime Minister that promotes and facilitates both domestic and foreign investment in Thailand. It plays a central role in supporting industries that contribute to the country’s economic growth and long-term development.
Key Functions of BOI Thailand
- Investment promotion: Encourages investment in targeted industries such as technology, renewable energy, advanced manufacturing, agriculture, digital services, and healthcare.
- Tax incentives: Provides corporate income tax exemptions or reductions, as well as exemptions from import duties on machinery and raw materials.
- Non-tax incentives: Grants benefits such as 100% foreign ownership in approved sectors, land ownership rights for foreign entities, and streamlined visa and work permit processes for foreign employees.
- Regulatory support: Serves as a “one-stop service” center, helping investors navigate business registration, licenses, and permits.
Thailand generally restricts foreign ownership in many sectors under the Foreign Business Act. BOI promotion allows investors to overcome these restrictions while accessing significant financial and operational advantages.
