B2B Requirements

B2B e-invoicing is voluntary with no mandate planned. The government encourages voluntary adoption. Luxembourg uses a Peppol-centric system with the entire infrastructure built on Peppol. The 2025-2030 government strategy explores using Peppol beyond invoicing, including potential VAT integration.

Technical Requirements

Luxembourg uses the Peppol network as its backbone. Accepted formats are Peppol BIS 3.0 (primary), UBL 2.1, and UN/CEFACT CII - any format compatible with UBL 2.1 meeting Directive 2014/55/EU. Compliance standard is EN 16931-1:2017. Luxembourg uses the standard Peppol CIUS with no national CIUS. The Centre for Information Technology of the State (CTIE) operates as the central authority. The Ministry for Digitalisation serves as the Peppol Authority. MyGuichet.lu portal is available for manual submission.
