Understanding BOI Project Approval Criteria in Thailand: What Investors Must Know
Thailand continues to attract global investors through the Board of Investment (BOI), offering a wide range of incentives for businesses that meet its criteria. However, before diving into your investment plans, it’s essential to understand the core BOI project approval requirements. Meeting these conditions not only ensures approval but also secures your eligibility for tax exemptions and other benefits.

Value-Added Requirements
The BOI expects projects to contribute meaningfully to the Thai economy. In most sectors, your project must generate at least 20% value-added from revenue. However, for industries such as agriculture, electronics, and coil centers, the threshold is 10%.
This value addition demonstrates that your business is not just trading or assembling but actively contributing through innovation or processing.
Use of Modern Machinery and Technology
To maintain high-quality standards, BOI-approved projects must adopt modern production processes and new machinery.
Used machinery is only allowed under special circumstances, provided it meets strict criteria, such as:
Clear inspection and test-run reports
Machinery performance certification
Environmental safety and energy efficiency evaluations
These requirements ensure that Thailand remains competitive in terms of both productivity and sustainability.
Certification of Quality Standards
If your project has an investment of over 10 million THB (excluding land and working capital), you must obtain international certifications such as ISO 9000, ISO 14000, or an equivalent.
This certification must be completed within two years of starting full operations. Failing to comply could lead to a reduction in your corporate income tax exemption by one year—a significant incentive loss.
Value-Added Requirements
All BOI projects must show clear steps to protect the environment. This includes:
Implementing pollution control and waste management systems
Adhering to relevant Environmental Impact Assessment (EIA) requirements
Following stricter environmental guidelines if your project is located in Rayong province
Sustainability and environmental compliance are no longer optional—they’re central to project approval.
Capital Investment & Financial Feasibility
To qualify for BOI promotion, your business must:
Invest at least 1 million THB (excluding land and working capital)
Maintain a debt-to-equity ratio of no more than 3:1 (for new projects)
Submit a feasibility study if your total investment exceeds 2,000 million THB
For knowledge-based businesses, the capital requirement is tied to minimum salary expenses of local employees.
Meeting these BOI criteria ensures your project is aligned with Thailand’s economic goals—adding value, being environmentally responsible, and maintaining operational quality. Whether you’re establishing a new entity or expanding an existing one, aligning with these standards improves your chances of BOI approval and long-term success in Thailand.
If you’re unsure how to proceed, consider working with an experienced consultant or accounting firm that understands the process and can guide you every step of the way.
