OECD engagement programs with Thailand
Accession track
Formal accession talks opened June 2024

Tax transparency
BEPS Pillar 1 and Pillar 2 alignment

Watchpoints 2025–2026
Accession milestones
Legal-instrument adoption pace
OECD accession requires Thailand to align domestic law with ~250 OECD legal instruments. Progress on competition law, anti-bribery, state-owned enterprise governance will determine timeline.
Pillar 2 impact
Global minimum tax on Thai FDI
Thailand's Pillar 2 implementation (15% global minimum effective tax rate from 2025) affects BOI incentive structures and multinational investment decisions in the EEC.
PISA 2025
Education performance benchmark
PISA 2025 results (due 2026) will reassess Thai student performance; a material improvement supports accession narrative; deterioration would pressure education-reform budget.
