Board of Investment Registration in Thailand

BOI Registration

BOI (Board of Investment) Law, is a promotional policy created in 1954, when the Thai government announced its Industrial Promotion Act. The government started actively subsidizing and promoting incentives for foreign skilled workers along with businesses willing to open and operate in the Kingdom of Thailand. Through the Thailand Board of Investment law, the government guarantees not to interfere with or nationalize foreign entities or businesses. Thailand was the first country in the region to have such an investment law.

BOI Thailand helps foreign businesses to establish their operations in Thailand and make sure that their activities will also be beneficial to the Kingdom. Furthermore, BOI application process is quite strict in the essence that it must comply with the regulations and the requirements of the application and focus on providing new technologies and benefits to Thailand. Foreign workers / BOI applicants, and newly established BOI companies need to be considered a valuable investment for Thailand.

The Investment Promotion Act

Under the Thai Investment Promotion Act, Section 16 defines the BOI promotion as: “The activities which are eligible for an investment promotion by the Board are those which are important and beneficial to the economic and social development, and security of the country, activities that involve production for export, activities which have a high content of capital, labor, or service or activities which utilize agricultural produce or natural resources as raw materials, provided that in the opinion of the Board, they are non-existent in the Kingdom, or existent but inadequate, or use out-of-date production processes.  ‍

The Board shall make an announcement designating the types and sizes of investment activity eligible for an investment promotion certificate and may stipulate there in the conditions under which promotion is to be granted and may amend or abolish those conditions at any time. ‍
In the case where the Board is of the opinion that any activity announced to be eligible for promotion under paragraph two no longer requires to be promoted, it may announce a temporary or permanent cancellation of promotion for that activity.” ‍

The Office of the Board of Investment is a government agency under the Office of the Prime Minister. Its main roles and responsibilities are to promote investment. Here are some of the Thailand Board of Investment promotion policies and main laws to protect a promoted person:

  • The State shall not nationalize the activity of the promoted person.
