Corporate - Significant developments

Vietnam witnessed significant recent developments related to BEPS (including MLI and Pillar 2 - Global Minimum Tax) and e-commerce activities. More importantly, Vietnam has made significant efforts to reform a number of key tax laws. Please also refer to the taxes on corporate income for comments relating to Pillar 2.

Taxing e-commerce activities

In September 2021, the Ministry of Finance (MoF) officially issued Circular 80/2021/TT-BTC (Circular 80) providing detailed guidance on the Law on Tax Administration on various matters, which also have a chapter focus on the tax filing mechanism for foreign companies doing e-commerce, digital business, and other business in Vietnam without a permanent establishment (PE). The General Department of Taxation (GDT) officially launched the portal for direct tax registration, declaration, and payments by e-commerce companies in Vietnam on 21 March 2022. The GDT published the names of 211 foreign companies registering up to Dec 2025.

According to the new Law on Corporate Income Tax (CIT), which took effect from 1 October 2025, foreign companies using e-commerce and digital platforms to supply goods/services in Vietnam are now formally included within the scope of the new CIT Law. In addition, these platforms are now officially included in the definition of PEs, potentially impacting double taxation agreement (DTA) exemption claims.

BEPS landscape

On 9 February 2022, Vietnam signed the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (“the Convention” or “the MLI”), becoming the 99th jurisdiction to join the Convention. As a result, many Vietnam’s double tax agreements (”DTAs”) would be amended once the MLI came into effect. Taxpayers should be aware of these potential changes to DTAs and the impact this may have on their plans for structuring their investments and transactions to claim treaty benefits in Vietnam.

In May 2023, Viet Nam deposited its instrument of ratification for the MLI (BEPS Convention). The BEPS Convention entered into force on 1 September 2023 for Vietnam.
