On June 16, 2025, the National Assembly of Vietnam adopted Law No. 75/2025/QH15 amending and supplementing a number of articles of the 2012 Advertising Law, with an effective date of January 1, 2026. The amended Advertising Law was enacted to further refine the legal framework for advertising activities in the modern era. Online Advertising Under the amended Advertising Law, “online advertising” is defined to encompass not only advertising on electronic newspapers and electronic information pages (as provided under the 2012 Advertising Law) but also advertising on other electronic venues, including social media, online applications, and digital platforms with internet connection. The amended Advertising Law also imposes new requirements for online advertising, including: Identification signs: Advertisements must have clear identifiable signs in numbers, letters, symbols, images, or sounds to distinguish them from non-advertising content. Control features: For advertisements not in fixed areas, there must be easily recognizable features and icons that allow recipients to turn off the advertisement, notify the service provider of violating advertising content, and refuse to view inappropriate advertising content. Linked content: Content in the links embedded in advertisements must comply with the law. Advertising service providers and publishers must have measures to check and monitor the linked content. Advertising on social media: Organizations and enterprises providing social media services must offer users features to distinguish advertising content from other content. Signage for sponsored content: When advertising, users of social media services must use signs to differentiate advertising or sponsored content from other content they provide. In response to the above requirements for online advertising, the amended Advertising Law sets out obligations of advertisers, advertising service providers, advertising publishers, and advertising conveyors in relation to online advertising. Among these, it is notably the responsibility of individuals and organizations engaging in online advertising to prevent and remove violating

On June 20, 2025, Cambodia’s Ministry of Economy and Finance issued Instruction No. 19116 to clarify when board members and company directors must receive salaries and pay payroll taxes. Board members and company directors who are not considered employees are subject to a withholding tax. This category consists of people who complete services for a nonresident individual and people who perform independent work for a company in Cambodia. Board members and company directors who are considered employees, including those appointed by a foreign head office to temporarily manage a company in Cambodia, must pay payroll taxes on any salary they receive, regardless of whether they are paid by a local or foreign branch of the company. The above obligations apply regardless of whether the person has a work permit. Board members and company directors are exempt from paying payroll tax if they: Are not present and not performing a regular management role at the company despite being registered on the company’s statutes or patent tax card; Participate only in board meetings and occasional shareholder meetings; and Do not receive a salary from a company in Cambodia. Overall, this instruction provides an important clarification regarding the tax obligations of board members and company directors. Companies should pay attention to the classification of their board members and directors and be mindful of the exemption.   This article was written with the assistance of Tilleke & Gibbins interns Amelia Gemma Erickson and Amrin Keat.

On June 17, 2025, Cambodia’s Ministry of Economy and Finance issued Instruction No. 18574 on Tax Obligations for Share Premiums to clarify that enterprises are not required to pay any income tax on share premiums that meet the conditions set out in the instruction. As outlined in the relevant provisions of the Law on Taxation (Royal Kram No. NS/RKM/0523/004) and Prakas No. 578 MEF.PrK.GDT on Tax on Income, taxable income is the difference between an asset’s value at the beginning and end of a period. This calculation deducts capital contributions, which are not taxable. A share premium is the amount of money that a company receives in excess of the par value of a share when the company issues new shares to a shareholder through a share subscription. In other words, share premiums are capital contributions made by shareholders into the equity of the company and, as a result, are not taxable. However, the government may nevertheless view share premiums as taxable if the company fails to meet certain legal conditions. Cambodian law requires share subscriptions to be properly recorded in the company’s accounting books and supported by documentary evidence. The recent instruction states that if an enterprise does not have proper documentation, any increase in equity, such as a capital increase through share premiums, will be treated as taxable income in accordance with the law. The instruction provides the following example: Enterprise A issues 200,000 new shares to an investor. The shares were registered with a par value of KHR 4,000 per share and were sold for a sale price of KHR 10,000 per share. The share premium of KHR 1.2 billion, which is calculated by subtracting the total par value (KHR 800 million) from the total value of the new capital (KHR 2 billion), is a capital

As of July 1, 2025, all companies in Vietnam have new addresses. The country’s administrative map has been redrawn and relabeled as part of an ambitious government restructuring, and every address in the country has been modified to at least a small degree due to provinces merging, the district level of local government being eliminated, and the surviving administrative divisions being reconfigured and renamed. Companies operating in Vietnam should note the guidance below regarding their obligations. Business Registration Guidance issued by Vietnam’s Ministry of Finance under Official Letter No. 4370/BTC-DNTN dated April 5, 2025, regarding business registration in the event of changes to administrative boundaries, provides the following principles: Enterprises may continue to use their existing Enterprise Registration Certificates even when administrative boundaries have changed. There is no requirement to register a change of address solely due to these changes. Enterprises may choose to update their registered addresses either when submitting applications for other business registration changes or at their own discretion. Tax-Related Matters The Tax Department of the Ministry of Finance and Regional Tax Sub-Departments have further issued the following guidance on tax-related matters: The tax authorities will issue notifications regarding the update of taxpayers’ addresses according to the new administrative boundaries. These notifications will also include information on the directly managing tax authority. The notifications will be communicated via the taxpayer’s electronic tax transaction account, or the taxpayer’s email address through the legal representative’s eTax Mobile application. These notifications will serve as a basis for taxpayers to explain to relevant authorities or clarify to customers in cases where the address shown on the invoice is the address updated by the tax authority according to the new administrative boundaries, but the information on the Enterprise Registration Certificate still shows the address according to the old administrative boundaries.
