BOI — Board of Investment of Thailand

Supports Thailand investment through tax incentives, import waivers, and direct subsidies for promoted sectors.

Thailand's Board of Investment is a federal agency under the Office of the Prime Minister. It promotes foreign and domestic investment through tax and non-tax incentives, with the record placing its core activity in semiconductors, EVs, digital infrastructure, biotech, robotics, materials, agritech, aerospace, medtech, manufacturing, transport, energy, AI infrastructure, and hardware.

Its main instruments are corporate income tax exemptions, import-duty waivers on machinery and imported inputs, and land ownership rights for promoted companies. The incentive groups A1+, A1, A2, A3, A4, and B define the depth and duration of relief, while the Competitiveness Enhancement Fund adds direct subsidies of up to THB 100 million for qualifying projects.

Applications run through e-Investment Promotion, and BOI also handles visas and work permits for foreign employees through TIESC. It is strongest for firms that can meet investment thresholds and fit the promoted activity groups, especially in advanced electronics, EV supply chains, and data centers.
