Key Features of a Compliant Vietnamese Invoice
To ensure your invoices comply with Vietnamese law, they must contain specific mandatory information and adhere to prescribed formats. Since July 2022, electronic invoicing has been mandatory for all businesses in Vietnam.
Here's a checklist of essential elements:
- Mandatory Information: Each e-invoice must include the invoice name, serial number, unique e-invoice number, and comprehensive details for both the seller and buyer (name, address, and Tax Identification Number - TIN).
- Transaction Details: A clear description of the goods or services, unit of measure, quantity, and unit price (excluding VAT), along with the applicable VAT rate(s) and total payment, are required.
- Language and Format: All details of goods and services must be presented in Vietnamese. If a foreign language description is necessary, it should be placed in parentheses or below the Vietnamese text, using a smaller font size. The valid format for electronic invoices is XML.
- Dates and Signatures: The e-invoice must specify the issuance and signing dates, and include the electronic signatures of the seller. While a buyer's electronic signature is not always mandatory, parties can agree to include it.
- Compliance with Circular 68/2019/TT-BTC: This circular, effective from November 14, 2019, provides detailed guidance on the registration, issuance, and management of e-invoices, including content requirements and error handling.
Businesses with an annual turnover of less than VND 3 billion typically use "coded e-invoices" which include a verification code from the tax authorities, while larger businesses often use "uncoded e-invoices."
