B2G e-Invoicing Mandatory in Luxembourg

Following other European countries, like its neighbors France and Germany, Luxembourg recently passed a law to make public sector (B2G) e-invoicing mandatory. Joining this inevitable trend enables companies to reduce the cost of processing invoices, decrease the likelihood of invoice disputes, eliminate manual entry errors, and increase global tax compliance.

What does the law say? 

The Law of 13 December 2021 (amending the Law of 16 May 2019) provides the following obligations: 

  • For companies: to issue and transmit only electronic invoices, that is to say, XML files or files containing XML, which are compliant in the context of public procurement; 
  • For public-sector bodies: to use the common delivery network for the automated receipt of electronic invoices Peppol and, as long as they do not have their own access point to Peppol, the access point of the CTIE (Government IT Centre); 
  • For ministries and state administrations: to use the CTIE’s access point to Peppol. 

When will e-invoicing be mandatory? 

The following timelines are set by the law for companies to send e-invoices to public entities in Luxembourg: 

  • Large companies, 5 months after the entry into force of the law, i.e. on 18 May 2022;
  • Medium-sized companies, 10 months after entry into force, i.e. on 18 October 2022; and
  • Small and newly established companies, 15 months after entry into force, i.e. on 18 March 2023.


What delivery network supports this model? 

The Peppol Network is a common global framework for the cross-border exchange of electronic business documents. Peppol connects many existing platforms which facilitate and enables the automated issue, transmission and receipt of electronic invoices. Not only does this document exchange between the buyer and the seller make things convenient and easy, but also secure and compliant. 

The e-invoicing format used in Luxembourg is Peppol BIS 3.0. Basware has already started implementing large companies sending e-invoices to Luxembourg public entities via the Peppol Network. As a certified Peppol access point provider, Basware helps companies connect to the Peppol Network to send e-invoices in Luxembourg.
