What is the BOI?

The Thailand Board of Investment (“BOI”) is an agency formed by the Thai government tasked with promoting foreign investment into the Kingdom. It does so by incentivizing qualified investors with several benefits and providing information to facilitate a smoother investment process in Thailand. The Board operates directly under the Prime Minister’s Office.
