Following the enactment of the Tax Administration Law (TAL), Myanmar’s Ministry of Planning and Finance has issued Notification No. 44/2024, which outlines directives and procedures for addressing violations of tax law provisions. These procedures, which came into force on June 13, 2024, primarily focus on three key areas: tax evasion, impeding tax administration, and failure to preserve secrecy. The notification primarily aims to address tax evasion, impeding tax administration, and failure to preserve secrecy, classifying these offenses as either subject to arrest without warrant or not. Notably, tax evasion is classified as an offense subject to arrest without warrant, while impeding tax administration and failure to preserve secrecy are not. The notification also prescribed the forms for notifying taxpayers before taking any action. Tax Evasion Tax evasion refers to a taxpayer who willfully evades the assessment, payment, or collection of tax. Penalties for such offenses include fines of MMK 250,000 (approx. USD 120) or 100% of the evaded tax (whichever is greater), imprisonment for up to seven years, or both. The enforcement process for tax evasion requires the chief officer of the township revenue department or an officer in charge (the tax authority) to assess the relevant documents and information provided by the taxpayer. If a taxpayer is found to be evading tax, the tax authority must send a notice in the prescribed form for verification within 15 days. Taxpayers may apply for a one-time extension of 15 days to submit requested documents and make disclosures. If the taxpayer cannot fulfill the requirements as instructed, the tax authority will seek approval from the director general of the Internal Revenue Department (IRD) for criminal proceedings as cognizable offences. Impeding Tax Administration and Failure to Preserve Secrecy Impeding tax administration refers to obstruction or attempted obstruction of taxation staff or officers

In May and June 2024, Cambodia’s General Department of Taxation (GDT) issued two notable tax incentive packages that aim to encourage business growth in the country. The details of these incentives are outlined below. Tax Incentives for Expansion of Qualified Investment Projects The GDT’s May 10, 2024, regulation (Prakas No. 313 MEF. PrK. PD) provides income tax incentives for expansion of qualified investment projects (QIPs), including an income tax exemption for the following types of expansion: Expansion of existing production. Expansion through product line diversification within the same lines. Implementation of new technologies that enhance productivity or protect the environment. Other forms of expansion set out in future sub-decrees. The number of years for the income tax exemption depends on the investment activities of the QIP, in accordance with the business groupings provided in the Sub-Decree on the Implementation of the Investment Law in Cambodia—9 years for group 1, 6 years for group 2, and 3 years for group 3. After receiving approval for the QIP expansion from the Council for the Development of Cambodia (CDC) or one of its Provincial-Municipal Investment Sub-Committees (PMISs), the GDT will certify the income tax exemption period. The exemption begins on the date the enterprise first receives income from the QIP expansion. QIPs seeking this tax exemption need to declare the amount of money that they intend to use for the expansion. Once allowed, the company must use that money for construction materials or new production equipment before the expiration of the tax exemption period. The income tax exemption can be revoked if: The enterprise does not use the capital to expand the QIP by purchasing the construction material and new production equipment as requested for the expansion. The enterprise fails to invest the prescribed amount before the expiration of the tax exemption

Laos has returned its value-added tax rate to 10% from the 7% rate that had been observed for the last two years. The new rate was specified in Ordinance No. 003/PDT, dated March 19, 2024, and announced on the website of the Ministry of Trade and Commerce. Prior to this, the last announcement of an adjustment in the VAT rate came in the last week of December 2021, when the Ministry of Justice published the Law Amending Certain Provisions of the Laws on Tax No. 01/NA, dated August 7, 2021, in the Government Gazette. This law, which entered into force in January 2022, amended the VAT rate from 10% to 7%. Under Lao law, the ordinance is effective from its date of signing by the president of Laos (i.e., March 19, 2024). However, the tax authorities have indicated that the new rate will not be enforced immediately but will be implemented in the near future, such as when it is published in the Lao Official Gazette. This change of the VAT rate to 10% does not come as a surprise. Some international experts and organizations had been recommending that Laos adopt a 10% VAT rate given its current economic challenges, arguing that Laos should prioritize collecting tax and replenishing the state budget. This was, for instance, recommended by the World Bank in the November 2023 Lao PDR Economic Monitor. Tilleke & Gibbins will continue to monitor the situation to determine when the 10% VAT rate will be enforced. For more details on the rate changes, or on any aspect of tax law in Laos, please contact Tilleke & Gibbins at [email protected].

Thailand’s Revenue Department (RD) has issued a notification requiring electronic platforms to report their revenue from business operators on their platform. With this information, the RD intends to track business operators’ income from the sale of goods and services through electronic platforms in order to facilitate accurate and efficient tax collection. The notification, which was enacted on December 27, 2023, took effect on January 1, 2024. Under the notification, electronic platforms are required to compile a “special account” containing information on the revenue received from each business operator on their platform and submit it to the RD through the department’s electronic reporting system within 150 days of the end of the fiscal year. The notification defines “electronic platforms” as entities that intermediate between business operators (i.e., sellers of goods or providers of services via the electronic platform) and consumers for the purpose of enabling electronic transactions between the parties. This covers online marketplace operators, ride-hailing operators, food delivery operators, and so on. This reporting requirement applies to electronic platforms registered in Thailand that have (or previously had, starting from the notification’s effective date) annual revenue exceeding THB 1 billion (approx. USD 28.5 million), except for electronic platforms under the supervision of the Bank of Thailand or the Office of the Securities and Exchange Commission, such as payment service providers and cryptocurrency exchanges. Electronic platforms can appoint a third party to prepare and submit the required special account information to the RD on their behalf. Compliance Steps As the requirements established by this notification mean that the RD will now have direct access to information on the income earned by vendors and merchants on electronic platforms, these business operators—whether corporate or individual—should ensure that they faithfully disclose their earnings, submit tax payments correctly, and file income tax returns in a
