BOI (Board of Investment)
We specialize in helping businesses apply for BOI benefits, providing guidance on securing incentives and support for tax exemptions and investment promotions in Thailand.
The Board of Investment (BOI) is a government agency under the Office of the Prime Minister. Its primary responsibility is to promote both domestic and international investments to support Thai businesses. The BOI focuses on encouraging investments that help restructure Thailand’s economy into a new economic model. The agency has set three key goals to achieve this economic transformation:
- Innovative: An economy driven by technology, innovation, and creativity.
- Competitive: An economy with high competitiveness, able to adapt quickly and foster strong growth.
- Inclusive: An economy that considers environmental and social sustainability, while creating opportunities and reducing inequality.

Project Approval Criteria
- Investment promotion is considered on a project-by-project basis. The project must involve new investments in machinery for the entire production line. Existing projects cannot apply for promotion.
- The project must fall within a business category that is eligible for promotion at the time of application and must meet the conditions specific to that category.
- The project must have a minimum investment of at least 1 million THB (excluding land costs and working capital).
- The project must use modern production methods or service processes.
- The project must have a value-added percentage of at least 20% of revenue (except for agricultural and food businesses, electronics and parts, and metal cutting, which must have a minimum value-added of 10%).
- The project must have a debt-to-equity ratio not exceeding 3:1 for new projects. For expansion projects, the suitability will be evaluated on a case-by-case basis.
- The project must have sufficient and effective measures to prevent and reduce environmental impacts. For projects that may cause environmental harm, the committee will consider the location and methods for managing pollution.
