BANGKOK, THAILAND — Thailand’s Cabinet has approved legislation introducing a 15 percent global minimum corporate tax for large multinational enterprises, marking a significant step toward aligning the country’s tax system with international standards established under the Organisation for Economic Co-operation and Development (OECD) global tax framework.
The measure is intended to reduce profit shifting by multinational corporations to low-tax jurisdictions and ensure that large companies pay a minimum level of tax regardless of where profits are reported.
Government officials estimate that the policy could generate approximately 10 billion baht in additional annual revenue while strengthening Thailand’s position within the evolving international tax landscape.
Thailand Joins Global Tax Reform Initiative
The new framework aligns Thailand with the OECD’s global minimum tax initiative, which has been adopted or planned by numerous economies worldwide.
The international agreement seeks to establish a minimum effective corporate tax rate of 15 percent for multinational groups meeting specific revenue thresholds. The objective is to prevent companies from shifting profits to jurisdictions offering extremely low tax rates.
Supporters argue that the reforms create a more level playing field between multinational corporations and domestic businesses while improving tax fairness.
Government Seeks to Boost Revenue Collection
The proposal has been strongly supported by Finance Ministry officials, who view the measure as an important modernization of Thailand’s tax system.
Ekniti Nitithanprapas has argued that the policy will help ensure that large international corporations contribute an appropriate share of tax revenue while reducing opportunities for aggressive tax planning.
Officials estimate that implementation could increase government revenues by roughly 10 billion baht annually, providing additional fiscal resources for public services, infrastructure, and economic development initiatives.
Focus on Large Multinational Enterprises
The tax is expected to apply primarily to major multinational corporations operating across multiple jurisdictions rather than small and medium-sized enterprises.
Companies that already pay effective tax rates above 15 percent in Thailand are unlikely to face significant changes. However, multinational groups utilizing complex international structures may experience increased tax obligations under the new framework.
Tax experts note that the reform reflects a broader global trend toward greater transparency and coordination among tax authorities.
Business Community Evaluates Impact
The business sector is now assessing the implications of the new rules on investment decisions, corporate structures, and financial planning.
Some analysts believe the impact on foreign investment will be limited because many multinational corporations are already preparing for similar regulations in other countries. Others argue that implementation details will be critical in determining how businesses adapt to the new requirements.
Government officials maintain that the policy is designed to enhance tax certainty and align Thailand with internationally recognized standards rather than discourage investment.
Part of a Broader Global Trend
The OECD-led global minimum tax initiative has gained momentum in recent years as governments seek to address tax avoidance strategies used by some multinational enterprises.
Advocates argue that international cooperation is necessary to prevent a race to the bottom in corporate tax rates and ensure that countries receive a fair share of revenues generated within their economies.
Thailand’s decision places it among a growing number of jurisdictions implementing measures intended to modernize tax systems and strengthen revenue collection.
Next Steps
Following Cabinet approval, the legislation is expected to proceed through the necessary legal and regulatory processes before full implementation.
Tax authorities are expected to release detailed guidance outlining compliance requirements, reporting obligations, and timelines for affected corporations.
As multinational businesses review the new framework, policymakers will be watching closely to assess its impact on revenue collection, investment activity, and Thailand’s competitiveness in the global economy.
