What is BOI?

The Thailand Board of Investment (BOI) is the government agency that promotes investment in the country by offering incentives to businesses in targeted industries. Approved companies can receive benefits such as corporate income tax exemptions, import duty relief on machinery, land ownership rights, easier work permits for foreign staff, and, for many promoted activities, majority or full foreign ownership. In short, BOI promotion can make setting up and running a business in Thailand faster, simpler, and more cost-effective.

Who Qualifies?
 

Your business may be eligible for BOI promotion if:
 

• Your business activity is on the BOI’s list of promoted activities, such as manufacturing, technology, digital services, R&D, renewable energy, or regional headquarters.

• Your project meets the minimum investment, which is generally THB 1 million (excluding the cost of land and working capital) unless specified otherwise on the list of activities.

• For new projects, the debt-to-equity ratio does not exceed 3 to 1.

• Your project uses modern technology and processes and meets environmental standards.

• Larger projects can provide a feasibility study when required by the BOI.
