Vietnam has enforced mandatory e-invoicing nationwide since July 2022. All e-invoices must be issued in standardized XML format, digitally signed (except POS), and either cleared in real-time with a tax authority code or reported to the General Department of Taxation (GDT) on the same day of issuance. The regime covers domestic B2B, B2C, B2G and export transactions. Imports are excluded. E-invoices must be archived for 10 years in original electronic form. Pre-filled VAT returns are not yet available.
