The Department of Taxation provides this guidance in Official Dispatch No. 7403/CT-TMDT on tax liabilities of individuals providing digital information content products and services and affiliate marketing services in e-commerce.
According to Section 3 of Official Dispatch No. 7403/CT-TMDT, an enterprise’s expenses shall be included in deductible expenses upon determining corporate income tax if all conditions prescribed in Article 9 of the 2025 Law on Corporate Income Tax and Clause 1, Article 9 of Decree No. 320/2025/ND-CP are fully satisfied.
For enterprises using affiliate marketing services provided by business households and business individuals, the Official Dispatch provides guidance on supporting documents for each case. Business households and business individuals whose annual revenue exceeds VND 1 billion must register for the use of invoices.

The list must be signed by the enterprise’s legal representative or an authorized person, who shall be responsible therefor, in accordance with Point 1b, Article 9 of Decree No. 320/2025/ND-CP. In particular, in this case, where the value of goods or services purchased on a single day from each business household or individual is VND 5 million or more, the enterprise must make cashless payment.
Where goods or services are provided through an e-commerce platform, the seller may request the platform operator to provide the buyer’s information, transaction-related information, delivery time and confirmation of the order completion status to create an e-invoice. The right to request information and the responsibility to provide information are prescribed in Point 1c, Article 17:

And Clause 2, Article 19 of Decree No. 254/2026/ND-CP:
