Thailand International and Corporate Tax Snapshots 2026: A practical guide to Thailand’s evolving tax and investment landscape for Japanese investors

BANGKOK, August 2026. Thailand remains one of Southeast Asia's key investment destinations, offering a competitive tax regime, strategic investment incentives and a business-friendly environment for international investors. As global tax developments continue to impact the international tax environment, businesses operating across borders face increasing complexity in managing tax obligations, investment decisions and compliance requirements.

EY has released the latest edition of Thailand International and Corporate Tax Snapshots 2026 (Japanese Edition), a practical guide designed to help Japanese businesses, investors and multinational groups better understand Thailand's tax and investment framework. The publication provides an overview of key aspects of the Thai tax system, including corporate income tax, withholding tax, value-added tax, investment incentives and tax administration requirements.

The publication also highlights recent international tax developments affecting multinational enterprises, including Thailand's implementation of the Global Minimum Tax regime, as well as updates related to transfer pricing requirements and tax compliance obligations. In addition, it outlines available incentives administered by the Thailand Board of Investment (BOI), International Business Center (IBC) tax incentives and Long-Term Resident (LTR) visa programs that support foreign investment and regional business operations in Thailand.

Developed specifically for Japanese investors and businesses, the guide is intended as a concise reference for organizations seeking to establish, expand or manage operations in Thailand. It also provides practical information on business structures, tax treaties, tax-free reorganizations and key filing requirements to support informed decision-making in an increasingly dynamic business environment.
