Mandatory information on an invoice in 2026

Avoid fines by knowing inside out all the mandatory legal information that must appear on your invoices this year.

The unique invoice number, the date of issue, the contact details of the issuer and the client remain the foundation of any invoice. The intra-community VAT number and the SIRET are also essential.
