In today’s innovation-driven economy, government investment promotion has become a strategic catalyst for growth. The Board of Investment (BOI) plays a pivotal role by offering a comprehensive suite of incentives designed to attract high-tech and innovative projects. These benefits—ranging from tax exemptions to non-tax facilitation—are specifically curated to enhance Thailand’s global competitiveness and support the transition toward a new, technology-based economic model.

Investment promotion under the Investment Promotion Act B.E. 2520 (1977) is primarily designed to restructure Thailand’s economy and overcome the middle-income trap. The focus is strategically placed on Target Industries (S-Curve), prioritizing sustainability, resource efficiency, and the transfer of advanced technologies.

There is a common misconception that BOI incentives are reserved exclusively for multinational corporations. In reality, Thai investors and SMEs are currently among the BOI’s highest priority groups. To qualify, businesses must meet the following criteria:

• Legal Entity Must be registered in Thailand as a Limited Company, Public Limited Company, or Limited Partnership.
• Business Scale Open to a wide spectrum of enterprises, from agile Startups to large-scale Industrial Manufacturers.
• Project Status The application must be for a “New Investment Project” or an “Investment Expansion” (existing operations without new improvements or upgrades are generally not eligible).

The BOI offers more than just tax breaks; it serves as a strategic partner for your long-term success in Thailand. Here are the core benefits:

• Inclusivity for All Scales Support is available to both Thai and foreign investors of all business sizes. Incentives are granted on a per-project basis, allowing for flexible investment planning.
• Comprehensive Coverage Promotion extends across the Agriculture, Industrial, and Service sectors. While support is nationwide, additional privileges are strategically categorized based on Target Locations (such as the EEC).
• Economic Drivers Investments are encouraged to enhance Global Competitiveness, boost exports, create high-value employment, and promote income distribution across local communities.
• Cost & Risk Mitigation Substantially reduce initial operational costs and financial risks through various incentives, creating a more secure foundation for your new venture.
• Seamless Facilitation & Networking Enjoy streamlined administrative processes for both domestic and international investors, fostering vital Business Connections and supply chain integration.

The BOI categorizes investment projects based on two primary criteria: The Level of Technology and Strategic Importance to Thailand’s Supply Chain. These are broadly divided into two main categories: Group A (focusing on Corporate Income Tax benefits) and Group B (focusing on Import Duty and Facilitation benefits).

This group is dedicated to high-impact sectors that advance Thailand’s technological capabilities.

• Group A1+ (The Innovation Leaders) Focuses on projects that generate new knowledge and “Deep Tech,” such as Research & Development (R&D) and Advanced Engineering Design. These are the key drivers in transforming Thailand into a regional technology hub.
• Groups A1 – A2 (The Tech Pillars) Covers complex upstream industries, digital infrastructure, and targeted high-tech manufacturing processes.
• Groups A3 – A4 (The Ecosystem Supporters) Includes industries that complete the economic ecosystem. While the technological complexity may be lower than A1, these sectors remain vital gears in driving the overall economy.

This group comprises businesses that may not utilize high-level technology but are essential links in the production chain. These supporting activities ensure that manufacturing and export sectors operate smoothly.

• Primary Benefits Projects in this group primarily receive Import Duty Exemptions on machinery and essential raw materials.

The BOI has strategically classified promoted industries into groups where Thailand holds high potential and a strong demand for technological advancement. These core sectors include:

This sector focuses on leveraging advanced biotechnology to add significant value to biological resources:

• Smart Agriculture Implementation of sensor systems, IoT, and AI-driven farm management.
• Future Food High-innovation food products utilizing advanced processing techniques.
• Medical Industry Manufacturing of high-end medical devices and research-intensive pharmaceuticals.

• EV Ecosystem Comprehensive support for EV manufacturing, high-performance battery production, and the development of nationwide charging station networks.
• Smart Electronics Production of advanced Multi-Layer Printed Circuit Boards (PCBs) and upstream semiconductor industries.

Focusing on the foundation of software infrastructure and digital innovation:

• Digital Enterprises Development of enterprise-grade software, Data Centers, and specialized Cloud Services.
• Creative Industries Digital content production and high-end animation utilizing advanced digital tools and platforms.

To ensure that promoted projects deliver tangible and sustainable benefits to the national economy, the BOI evaluates applications based on four core pillars:

• Value Added The project must generate a value-added ratio of at least 20% of total revenue. (Exceptions: Agriculture, Electronics, and Metal Cutting sectors require a minimum of 10%).
• Innovation & Technology Projects must utilize modern, high-efficiency production processes. If utilizing used machinery from abroad, specific BOI criteria and certifications must be met.
• Environmental Governance Investors must implement robust measures to prevent or mitigate environmental impacts, adhering to both Thai laws and international standards.

• Debt-to-Equity (D/E) Ratio For new investment projects, the D/E ratio must not exceed 3:1.
• Minimum Investment A minimum investment of 1 million THB is required (excluding land costs and working capital).
• Registered Capital The registered capital must be fully paid up according to the specified proportion before the Promotion Certificate is issued.

• Investment Type Applications must represent a new investment or a capacity expansion with clearly separated production units (unless applying under specific “Industrial Upgrade” measures).
• Specific Qualifications Projects must satisfy all additional requirements uniquely defined for each business category.

• Manufacturing and General Sectors Foreign investors are permitted to hold up to 100% of shares (unless otherwise stipulated by specific laws).
• List One Businesses Under the Foreign Business Act, certain protected sectors require Thai nationals to hold a combined stake of at least 51%.

Securing a BOI promotion is more than just obtaining tax privileges; it is a strategic seal of approval that positions your business for sustainable growth in the heart of Southeast Asia. As Thailand transitions toward a high-tech, innovation-led economy, the window of opportunity for early movers is wider than ever.

Whether you are a local SME looking to scale or a global startup ready to disrupt the market, the BOI provides the foundation, the protection, and the incentives you need to thrive. The future of Thai industry is being built today—ensure your business is part of the blueprint.
