Vietnam Clarifies Tax Obligations for E-Commerce and Digital Platforms

Vietnam’s e-commerce tax framework uses several collection mechanisms, with taxes withheld either by Vietnamese purchasers or by digital platform operators that handle ordering and payments. Where no withholding takes place, foreign suppliers must register, declare and pay Vietnamese taxes directly, while platforms and suppliers are also subject to recordkeeping, reporting and transaction-data obligations. 

Vietnam’s tax framework for e-commerce and digital platforms establishes several ways in which taxes can be collected from cross-border and platform-based transactions. Depending on how the transaction is structured, tax may be withheld by the Vietnamese purchaser, by the platform operator, or paid directly by the foreign supplier.

For B2B transactions, Vietnamese companies purchasing goods or services from foreign suppliers may be required to withhold and pay VAT, CIT and/or PIT at the time of payment. Where the Vietnamese purchaser has already fully withheld the relevant taxes, the foreign supplier does not need to declare the same income again, and the platform must be informed to avoid double withholding.

E-commerce and digital platform operators that provide both ordering and payment functions may also act as withholding agents. They can be required to withhold, declare and remit taxes on behalf of household businesses, individual sellers and foreign suppliers. Platforms must generally file withheld taxes monthly and may offset tax relating to cancelled or returned transactions.

Where tax is not withheld by either the purchaser or the platform, foreign suppliers must register, declare and pay tax directly in Vietnam. Regular suppliers generally file monthly, while non-recurring suppliers declare tax on a transaction-by-transaction basis.

Platform operators must also retain transaction records, manage tax-related information, provide data to the authorities when requested and process refunds linked to cancelled or returned transactions. Foreign suppliers must maintain accurate payment-account and transaction information and update the tax authority when relevant details change.

Pure transaction-matching services that do not participate in the payment process are excluded from these withholding obligations.
