On February 26, 2025, Thailand’s National Anti-Corruption Commission (NACC) issued a notification titled “Criteria for Individuals Living Together as Husband and Wife that Are Considered as De Facto Spouses (No. 2) B.E. 2568 (2025).” This new notification, published in the Government Gazette on March 7, 2025, took effect retroactively from January 22, 2025. Prior to this notification, the term “spouses” specifically included “individuals living together as husband and wife” without registering marriage, referring to similar language at the time in Thailand’s Civil and Commercial Code. However, it was unclear whether this term included same-sex and other nontraditional couples. After the Marriage Equality Act revised this language in the Civil and Commercial Code to only refer to “spouses” (with a gender-neutral Thai word), the NACC took the opportunity to issue a new notification that simply replaces any mention of “husband and wife” with “spouses,” thereby removing the ambiguity. As a result, this new notification covers same-sex de facto spouses of politicians and high-ranking officials. These spouses’ assets must now be declared together with the officials’ assets. Additionally, same-sex de facto spouses of state officials are prohibited from engaging in business with the Thai government that may present conflicts of interest. Importantly, the notification also impacts the interpretation of the Office of the Prime Minister’s (OPM) Regulation on the Giving or Receiving of Gifts by Public Officials B.E. 2565 (2022). In this regard, same-sex de facto spouses of government officials are now also prohibited from accepting gifts or other benefits related to official duties. This is because the OPM regulation references the NACC definitions when defining “family members” to include “de facto husband and wife.” Under the OPM regulation, public officials and their supervisors are strictly prohibited from permitting or condoning family members’ acceptance of gifts or other benefits related to

Thailand is continuing on its path toward comprehensive legislation to address climate change. In November 2024, the country’s Ministry of Natural Resources and Environment (MNRE) launched a public hearing on a new draft Climate Change Act following revisions made after an earlier hearing on a previous draft of the act. The revised version strengthens Thailand’s climate policy framework by introducing the Carbon Border Adjustment Mechanism (CBAM), modeled after the EU’s system of the same name. The new draft also restructures the planned Emissions Trading Scheme (ETS) and enhances carbon-tax provisions. These initiatives aim to minimize carbon leakage, promote fair competition for domestic industries, and encourage lower greenhouse gas (GHG) emissions. As of March 2025, the Department of Climate Change and Environment, under the MNRE, is awaiting the Ministry of Finance’s input on the draft act’s establishment of the Climate Fund, a fund to support business innovation in responding to climate change. After incorporating this feedback, the department will submit the refined draft for cabinet approval, expected in 2025. The legislation will then undergo Council of State review, with implementation expected in 2026. Key Provisions The draft Climate Change Act contains a number of provisions that will affect businesses. Some of the most relevant are discussed below. Mandatory ETS The ETS is a mandatory mechanism designed to control GHG emissions by setting emissions caps for designated industries in alignment with national targets. Under this system, businesses receive emissions allowances allocated through free allocation or auctions. This scheme incentivizes emissions reductions by allowing businesses that emit less than their allocated allowances to sell their surplus allowances. The specific business sectors covered by the ETS have not yet been identified in the draft act, as details are expected to be in subordinate legislation. However, it is anticipated that the sectors will align

On January 1, 2025, the Department of Business Development (DBD) in Thailand’s Ministry of Commerce implemented new stringent corporate registration screening measures in collaboration with several other government agencies to prevent entities from opening corporate mule accounts to commit criminal activities in Thailand. The DBD’s Order of the Office of Central Company and Partnership Registration No. 3/2024 stipulates a new method for registering the establishment of partnerships and limited companies for people who have been involved in underlying crimes or who are owners of bank accounts that are being used for underlying crime, as per the notification of the Anti-Online Scam Operation Center (AOC) to the Anti-Money Laundering Office (AMLO) and the collated AMLO list of such persons. The order establishes the following key requirements: Managing partners and directors of partnerships and limited companies, respectively, whose names have been listed by the AMLO as a person who is involved in an underlying offense, or as the owner of a bank account being used for the underlying offense, must appear before the registrar in person. The concerned persons cited on the AMLO list must provide valid documentation of their identity to the DBD registrar (e.g., national identification card, government official identification card, government or state enterprise employee identification card, alien identification card, passport, document used in lieu of a travel document, or other similar documents with photo identification). This collaboration between the DBD and various relevant government agencies aims to eradicate the problem of fraudsters using mule accounts set up under legally established entities to deceive the public. It also seeks to enhance checks and screening of corporate mule accounts that are used to carry out criminal activities such as money laundering or cybercrime. These actions are part of the Thai government’s broader policy to suppress economic crimes. For more

Vietnam’s Ministry of Finance has released a draft Decree on Tax Administration for E-Commerce and Digital Platforms (“Draft Decree”), introducing significant tax compliance obligations that could reshape how digital platforms, and individuals and business households conducting business through the platforms, manage their tax responsibilities. Aimed at strengthening tax enforcement, the Draft Decree requires e-commerce and digital platforms to actively track and withhold taxes from business households and individual sellers, and remit payments to tax authorities. While it has not yet been promulgated, the Draft Decree is expected to take effect on April 1, 2025, leaving platforms with a limited window to prepare for compliance. Who Is Affected by the New Tax Rules? The Draft Decree significantly broadens the tax administration scope beyond traditional e-commerce platforms to cover a wide range of digital economy participants. Specifically, the Draft Decree places direct tax-related responsibilities on two major categories (collectively, “Regulated Operators”): E-commerce and digital platforms with payment functions (e.g., platforms that process buyer payments via e-wallets, bank transfers, cards, or cash-on-delivery); and Other digital-economy players that enable e-commerce transactions, including (i) intermediary service platforms connecting service providers with consumers, (ii) digital content platforms, (iii) online advertising providers, (iv) cloud computing and data storage providers, (v) social media platforms engaged in business activities (e.g., live-stream, in-app transactions), (vi) online education, gaming, and digital entertainment platforms generating revenue from digital transactions, (vii) Vietnam-based partners of foreign digital service providers facilitating local payments for overseas platforms, and (viii) intermediary payment service providers handling financial transactions for e-commerce activities. Under the Draft Decree, Regulated Operators will be required to track, report, and enforce tax compliance for both resident and nonresident individuals and households conducting business through their platforms (“Sellers”). What New Tax Obligations Do Platforms Face? Onshore platforms For the first time, Regulated Operators will
