Thailand’s Strategic Tax Reform: Tax Credit Incentives to Drive Investment and Startup Growth Under the Global Minimum Tax Framework
Thailand is implementing comprehensive tax reform measures to strengthen its competitive position within the evolving global investment landscape. In alignment with the Organization for Economic Co-operation and Development (OECD) Global Minimum Tax (GMT) framework, the government has introduced Qualified Refundable Tax Credits (QRTCs) designed to attract high-quality foreign direct investment and foster domestic innovation. These strategic initiatives, coupled with an enhanced startup support program, aim to bolster national competitiveness, retain strategic industries, and promote sustainable economic growth.
Legislative Framework and Approval
On August 1, 2025, Thailand’s National Committee on Enhancing Competitiveness for Targeted Industries Policies formally approved amendments to the National Competitiveness Enhancement Act of 2017. This legislative milestone establishes the foundation for implementing new investment rights and incentives, including refundable tax credits, in direct response to GMT adoption requirements.
OECD Alignment and Global Minimum Tax Response
The GMT framework mandates that multinational enterprises (MNEs) with consolidated global revenues exceeding €750 million (approximately THB 28 billion) maintain a minimum effective tax rate of 15% across all operational jurisdictions. When host countries offer tax incentives that reduce the effective tax rate below this threshold, the MNE’s home country reserves the right to impose supplementary taxes to capture the differential.
To preserve Thailand’s attractiveness as a foreign investment destination, the National Committee has strategically approved amendments introducing QRTCs as a new category of investment incentives. This mechanism positions Thailand to effectively compete for investment capital, maintain existing manufacturing operations in targeted sectors, and stimulate new investments that enhance competitiveness while driving sustainable economic development.
Qualified Refundable Tax Credit Structure
These tax credits will be available to qualified foreign investors, particularly those engaged in:
- Manufacturing and Research & Development Operations: Establishing or expanding production facilities and R&D centers in Thailand
- High-Value Employment Generation: Creating positions that promote skilled workforce development and knowledge transfer
- Sustainable Innovation: Advancing environmental sustainability through green technology adoption and innovative solutions
The credits function as flexible instruments that can be applied toward various tax obligations, including corporate income tax, top-up tax under GMT provisions, and other applicable taxes and duties. Should credit balances remain after tax applications, investors may request cash refunds within a four-year period, subject to established eligibility criteria and regulatory requirements.
Enhanced Startup Support Framework
Complementing international tax policy reforms, the Thai government has prioritized domestic innovation through targeted support for Thai startups operating in deep technology (Deep Tech) sectors where Thailand demonstrates competitive advantages. Priority sectors include agriculture and food technology, biotechnology, robotics and automation, artificial intelligence, medical technology, and green industries.
Support is delivered through a Matching Fund mechanism administered under the Competitiveness Enhancement Fund, managed by the Board of Investment (BOI). The program operates under the following parameters:
- Co-Investment Requirements: Startups must secure minimum co-investment of THB 10 million from venture capital funds registered with the National Innovation Agency (NIA) or established by licensed financial institutions operating in Thailand
- Matching Fund Provision: The BOI may provide matching funds equivalent to venture capital contributions, capped at THB 20 million per project
Ownership and Control Requirements
To ensure direct benefits accrue to Thai-owned enterprises, the following ownership structures are mandated:
- Thai Majority Ownership: Thai nationals or Thai-registered entities must maintain at least 51% shareholding
- Founder Control: founders must collectively retain at least 60% of total shares
Therefore, as long as the startups remains under this promotional project or has not yet received the full amount of matching funds from the BOI, it is required to maintain a minimum of 51% Thai shareholding. Additionally, the founders, including both Thai and foreigners, must collectively retain at least 60% of the control throughout this period.
Strategic Implications and Outlook
The amendment to the National Competitiveness Enhancement Act provides the BOI with sophisticated policy instruments to reinforce investor confidence during a period of significant transformation in global tax policy. While QRTC implementation awaits Cabinet approval and subsequent regulatory framework development by the Revenue Department, this initiative represents a crucial evolution in Thailand’s investment promotion strategy.
Simultaneously, the strengthened startup promotion measures will expand market opportunities and accelerate the development of Thai Deep Tech enterprises, further establishing Thailand’s position as a regional hub for innovation-driven, sustainable investment.
These coordinated policy measures demonstrate Thailand’s proactive approach to navigating the complexities of international tax harmonization while maintaining its competitive edge in attracting both foreign direct investment and nurturing domestic innovation capabilities.
