E-Invoicing in Luxembourg

B2G MandatoryPeppol

Recently verified: 16 February 2026

Luxembourg has fully implemented B2G e-invoicing with all businesses required to issue e-invoices to public sector entities since March 2023. The infrastructure is entirely Peppol-based with no national CIUS — standard Peppol BIS 3.0 applies. B2B e-invoicing remains voluntary with no mandate planned.

Implementation Notes

Pure Peppol, no local customization. Luxembourg uses standard Peppol BIS 3.0 with no national CIUS, making it one of the simplest markets to support if you already have Peppol integration. MyGuichet.lu is available as a fallback for manual submission. CTIE (Centre for Information Technology of the State) operates the central authority. The Ministry for Digitalisation serves as the Peppol Authority.
