The Top-up Tax Law in Thailand (Part 1)
The Thai Revenue Department (“TRD”) recently promulgated the Emergency Decree on Top-up Tax 2024 (B.E. 2567) (“Top-Up Tax Decree”), in accordance with the OECD standards. This decree is in effect for the accounting period commencing on or after 1 January 20251.
The Top-Up Tax Decree gives the TRD the right to collect additional tax, in a manner similar to laws already enacted in 28 other countries (including Greece, South Korea, Canada, Japan, Denmark, Turkey, the Netherlands, New Zealand, France, Finland, Germany, Spain, Sweden, the United Kingdom, Australia, Italy, Ireland and Vietnam). Other ASEAN countries, such as Malaysia, Singapore, Indonesia, and the Government of the Hong Kong Special Administrative Region, are expected to introduce similar laws in 2025.
The Top-Up Tax Decree will apply to Large Multinational Enterprises (“MNEs”) that are Ultimate Parent Entities (“UPEs”) and have consolidated financial statements showing annual revenue of at least EURO 750 million for at least two of the four accounting periods preceding the accounting period under investigation. MNEs that operate in Thailand are subject to the Top-Up Tax Decree, whether they are Thai MNEs investing overseas or foreign MNEs investing in Thailand.
The TRD also is expected to issue secondary legislation related to the Top-Up Tax Decree, along with related guidelines governing tax filings, tax payment procedures, and the submission of GloBE Information Returns, and has plans to host a public seminar to provide additional clarification and guidance to stakeholders.
