Updates to Thailand’s Investment Promotion Regime
Overview of Recent Amendments to Investment Promotion Measures in Thailand
Pursuant to the Investment Promotion Act B.E. 2520 (1977), as amended, Thailand has established a comprehensive framework and institutional mechanisms for promoting investment. The primary objectives are to create an investment-friendly environment, foster industrial development, and promote equitable income distribution by granting investment incentives to business activities deemed significant and prioritized.
In furtherance of these objectives, the Board of Investment (BOI) issued Notification of the Board of Investment No. 9/2565 regarding Measures for the Promotion of Industries Critical to National Development (“BOI Notification No. 9/2565“). This notification establishes the categories of business activities eligible for investment promotion, together with the applicable conditions, criteria, and privileges granted to promoted projects, as detailed in the Schedule of Investment-Promoted Activities annexed thereto.
To align with Thailand’s evolving economic development policies and strategic direction, accommodate the rapid expansion of industrial activities, and enhance incentives for investors, the BOI issued two notifications dated 5 June B.E. 2568 (2025), which were published in the Royal Gazette on 22 January B.E. 2569 (2026). These notifications revise and update the investment promotion framework to reflect current economic and industrial conditions by amending certain categories of business activities eligible for investment promotion as prescribed in the Schedule of Investment-Promoted Activities. The key amendments are summarized below:
1. Notification of the Board of Investment No. Sor. 5/2568
Amendment to the List of Activities Eligible for Investment Promotion under BOI Notification No. 9/2565
This notification is issued pursuant to BOI Notification No. 9/2565, which prescribes the categories of business activities and conditions eligible for investment promotion as set forth in the Schedule of Investment-Promoted Activities. Certain categories have been amended to focus on investments that create added value, promote the adoption of modern technologies in the manufacturing sector, enhance the development of supply chains to ensure Thailand’s export-oriented production attains international recognition and delivers maximum benefits, and accommodate the rapid expansion of data center businesses by supporting Thailand’s advancement toward becoming a digital hub of the ASEAN region.
This notification revises the categories of business activities and conditions eligible for investment promotion with respect to 32 categories under the Schedule of Investment-Promoted Activities. The majority of these are activities that generate added value for the national economy, including the machinery and automotive industry, electrical appliances and electronics industry, metals and materials industry, public utilities, digital industry, and creative industry. Additionally, investment promotion for metal cutting activities (Category 5.4.10) has been discontinued and removed from the list of promoted activities. This notification applies to business operators who submit applications for investment promotion on or after 1 July B.E. 2568 (2025).
2. Notification of the Board of Investment No. Sor. 6/2568
Investment Promotion Measures for Tourism-Related Businesses in Secondary Cities
The public sector has provided support for tourism development in secondary cities, which are provinces that are not widely known but possess high tourism potential. To promote tourism, distribute income equitably, and sustainably expand economic opportunities to local communities, investment promotion measures have been introduced for tourism-related businesses located in designated secondary cities.
This notification revises the criteria and conditions for investment promotion applicable to certain categories of tourism-related businesses (including cruise terminals, hotels, international exhibition centers, and similar establishments), totaling 12 items under the Schedule of Investment-Promoted Activities. The location of the establishment serves as a key criterion for granting enhanced and more beneficial investment promotion privileges, such as extended periods of corporate income tax exemption, to create incentives for both domestic and foreign investors to invest in secondary cities and extend investment promotion benefits to tourism businesses located therein. This notification applies to business operators who submit applications for investment promotion on or after 5 June B.E. 2568 (2025).
Key Observations
1. Discontinuation of Metal Cutting Activities (Category 5.4.10)
Business activities previously eligible for investment promotion under Category 5.4.10 (metal cutting activities) are no longer entitled to apply for BOI promotion, as the BOI has formally discontinued investment promotion for this category. Businesses operating in the affected sectors should conduct a careful review of their current operations to determine whether they may qualify under other eligible promoted activities. Where necessary, they should consider restructuring their investment structures or business operations to ensure ongoing compliance with the revised BOI investment promotion framework.
2. Enhanced Incentives for Tourism-Related Businesses in Secondary Cities
Tourism-related businesses located in secondary cities, whether newly established or existing, may have opportunities to receive investment promotion incentives at a higher level than previously available, including longer and more favorable tax incentives, which may serve as a catalyst for increased investment. Conversely, businesses located in primary cities may not be entitled to the same level of preferential treatment as those located in secondary cities, which may result in heightened competitive pressure regarding operational costs.
Status and Legal Effect
These two notifications are issued pursuant to Section 16 of the Investment Promotion Act B.E. 2520 (1977), as amended, and shall be applied in conjunction with the Investment Promotion Act B.E. 2520 (1977) and BOI Notification No. 9/2565. In the event of any inconsistency or conflict between the conditions or criteria, the provisions of these two notifications shall prevail and be applied on a case-by-case basis to the relevant promoted businesses, taking into account the prevailing economic circumstances at the relevant time.
Furthermore, additional or amending notifications concerning investment-promoted activities may be issued in the future to reflect Thailand’s evolving economic conditions. Investors are therefore advised to closely monitor regulatory developments in order to formulate, review, and adjust their investment strategies in a timely and appropriate manner.
Conclusion
These two BOI notifications constitute a significant component of Thailand’s current legal and policy framework governing investment promotion. They clearly reflect the government’s policy orientation toward enhancing national competitiveness, promoting targeted high-value industries, supporting regional economic development, and refining the investment promotion regime to ensure its alignment with rapidly evolving economic and technological landscapes.
