BOI Thailand

Your end-to-end Board of Investment (BOI) solution in Thailand

What is Thailand’s Board of Investment (BOI)?

The BOI is a national government agency with the mission of developing Thailand through foreign direct investment. One of the ways it does this is through incentives to international businesses looking to expand or relocate to Thailand. These include tax and non-tax incentives and BOI-specific work permits that allow firms to employ foreign experts in Thailand.

Baan Thai Immigration Solutions is your single source of BOI expertise: Our bilingual counselors will help you through every step of the certification process.

Why apply for BOI certification?

BOI certification offers a range of benefits, including the ability to avoid many of the strict regulations on businesses in Thailand.

Yes, the BOI website is set up for online applications. You’ll soon discover, however, that the process gets derailed by opaque decision-making, unexpected requests, and technical difficulties.

The main BOI office is in Bangkok, and seven regional offices are located around the country. Note that BOI work permits are processed in the central Bangkok business district, not at the Immigration Center on the outskirts of the city.

There are also BOI offices in Japan, China, Korea, Taiwan, Indonesia, India, Vietnam, Germany, France, Sweden, Australia, and the USA. These are tasked with promoting Thai business and industry abroad.
