E-invoicing is no longer optional. It is already mandatory for invoices to the Luxembourg public sector, and the B2B obligation is taking shape for 2028-2030. Good news for Galux clients: we take care of it for you, at no extra cost.

B2G-compliant from day one, B2B-ready for 2028
Where does Luxembourg stand?
B2G: mandatory since 2019. Since 18 April 2019, formalised by the law of 13 December 2021, every invoice issued to a Luxembourg public entity (State, municipalities, public establishments) must be sent in structured electronic format via the PEPPOL network. The obligation applies to all companies, with no turnover threshold. A PDF invoice sent by email is no longer accepted by the public sector.
B2B: not mandatory yet, but it's coming. Business-to-business e-invoicing remains voluntary in Luxembourg in 2026. But ViDA was adopted at EU level in April 2025, and the Luxembourg legislator is now drafting the national framework that will plug into it.
How does it work in practice?
The Luxembourg standard is PEPPOL (Pan-European Public Procurement Online), a secure network that transports invoices in structured XML format. Three building blocks:
Structured XML
The invoice is machine-readable data, not a PDF. Standardised fields, automated validations, no re-keying on either side.
PEPPOL Access Points
Invoices transit via certified Access Points, each company identified by a PEPPOL ID (often based on its VAT number).
European interoperability
The same invoice flows to Luxembourg, Belgium, the Netherlands or Germany without a single change.
Four milestones to keep in mind
The Luxembourg e-invoicing roadmap is now public.
Companies that wait may find themselves scrambling in 2028. Anticipating costs less — especially when your accounting firm anticipates for you.
