B2G mandatory e-invoicing Luxembourg is following the lead of e-invoicing developments in neighbouring countries Belgium and the Netherlands, by mandating B2G e-invoicing in the country. E-invoicing is projected to take place in a phased implementation in line with the following timeframes:
  • 18 May 2022: Large companies in Luxembourg will be required to send e-invoices to the public authorities
  • 18 October 2022: medium-sized taxpayers will follow suit
  • 15 March 2023: small and new businesses will complete the transition to e-invoicing
Luxembourg will follow the path of many European countries by using the PEPPOL Network for B2G e-invoicing. This means that invoices will be converted into the standard PEPPOL BIS 3.0 format and transferred through the PEPPOL channel (AS4). It will also require companies to be connected to a PEPPOL Access Point, to facilitate connection with other participants on the PEPPOL Network. The move to e-invoicing will provide greater automation of the e-invoicing process, leading to reduced errors and cost-saving. Tungsten Network is compliant in Luxembourg and will follow e-invoicing developments in the country.

Joint incentive to reduce the VAT gap Belgium, Netherlands, and Luxembourg representatives have convened to discuss plans to reduce the VAT gap. Although Continuous Transaction Controls (CTC) have proven to be extremely popular in the past few years, with a means to reducing the VAT gap, the VAT gap remains high- 134 million Euros was lost in revenue the EU in 2019. Shared borders and economic interests between the 3 countries have prompted the countries to work together to reduce this gap yet further- a key factor in the implementation of e-invoicing mandates.

Further progress with B2G e-invoicing

Luxembourg is making significant progress with B2G e-invoicing, and has set out a timeframe for B2G e-invoicing in the country.
As with many other countries, the underlying aim is to introduce greater transparency within the tax authority domain, as well as improving efficiency of the transactions with the public sector.
Companies will be obliged to send invoices to government institutions via the PEPPOL Network.
The tax authority has acknowledged that this will instigate a radical overhaul in the way people work- and have therefore responded by outlining a phased approach for implementation, in line with the following:
• Large companies- mandatory to use e-invoicing from 18 May 2022;
• Medium companies- mandatory to use e-invoicing from 18 October 2022;
• Small companies: mandatory to use e-invoicing from 18 March 2023.
It is hoped that the phased implementation will allow companies to adapt their working models to accommodate B2G e-invoicing.
