For many years, transfer pricing (TP) compliance in Thailand was often viewed as a documentation exercise performed after year-end. That mindset is rapidly becoming obsolete. Thailand's Revenue Department (RD) has transformed TP enforcement from a reactive audit process into a data-driven risk management system that continuously analyzes corporate tax filings, financial statements, related-party disclosures, withholding tax records, and transfer pricing reporting.

For decades, tax compliance in Thailand revolved around physical tax invoices, manual reconciliations, and document retention practices. Finance departments maintained extensive archives of paper records, while tax audits often focused on reviewing historical documentation long after transactions had occurred. That model is rapidly disappearing.
For decades, Thailand's investment promotion framework relied heavily on corporate income tax (CIT) exemptions granted through the Board of Investment (BOI). These incentives successfully attracted foreign direct investment by reducing or eliminating tax burdens for qualifying projects. However, the implementation of the OECD's Pillar Two Global Minimum Tax framework has fundamentally altered this landscape.
