The emergency decree was enacted through expedited procedures to implement “pillar two” of the OECD’s Base Erosion and Profit Shifting (BEPS) 2.0 project’s Global Anti-Base Erosion (GloBE) Rules. This swift implementation ensures Thailand can collect relevant tax revenues and prevents potential revenue losses from MNEs that might otherwise shift profits to jurisdictions with lower tax rates or to countries that have already implemented similar top-up tax legislation. Key aspects of Thailand’s implementation of the global minimum tax through the emergency decree are described below.
