Starting October 1, 2026, Luxembourg will no longer accept XRechnung versions below 3.0. What businesses need to do now.
Companies sending electronic invoices to public contracting authorities in Luxembourg must review their invoice formats: Starting October 1, 2026, XRechnung versions below 3.0 will no longer be accepted.
This affects both invoices and credit notes in the UBL and UN/CEFACT CII syntaxes. Companies still using XRechnung 2.2.0 or 2.3.1 should upgrade to a current version early.
According to the official Luxembourg business portal, the following formats will no longer be accepted starting October 1, 2026:
The official Luxembourg overview mentions XRechnung 3.0.1. The currently published version by KoSIT is XRechnung 3.0.2. Compared to previous 3.0 versions, this contains only editorial changes and remains technically compatible with XRechnung 3.0.
Independent of the Luxembourg regulation, various outdated XRechnung profiles will be removed from the Peppol network on August 1, 2026. According to a notice from XStandards Einkauf, this affects:
The remaining profiles of XRechnung versions 2.2 and 2.3 are not expected to be removed from the Peppol network until after the publication of the new EN 16931, and at the earliest in 2027.
| Effective Date | Change |
|---|---|
| August 1, 2026 | Removal of selected outdated XRechnung profiles from the Peppol network. |
| October 1, 2026 | Luxembourg will no longer accept XRechnung versions below 3.0 for B2G invoices. |
A temporary upgrade to another older version is not recommended. Outdated XRechnung profiles are being gradually removed from receiving systems and the Peppol network. Direct migration to XRechnung 3.0 offers:
With current validation rules.
For national and international recipients.
Across the entire Peppol network.
Fewer subsequent adjustments required.
Better foundation for upcoming EN 16931 changes.
Consistent processing for all recipients.
Check which XRechnung version your ERP, accounting, or invoicing system generates.
The change affects not only invoices but also electronic credit notes.
Adjust custom interfaces, CSV mappings, and IDoc conversions.
Validate XML files against current XRechnung and EN 16931 rules before sending.
Conduct a test with your responsible e-invoicing or Peppol provider before the deadline.
Public contracting authorities may require additional references or identification numbers.
Invoice-Portal supports companies in creating, converting, validating, and transmitting electronic invoices:
Companies can continue to provide their existing invoice data from their ERP or accounting system. Invoice-Portal handles the conversion into the required electronic invoice format as well as the subsequent transmission.
Starting October 1, 2026, Luxembourg will no longer accept XRechnung versions below 3.0 for electronic invoices to public contracting authorities. Companies still using XRechnung 2.2.0 or 2.3.1 should update their systems and interfaces in a timely manner.
Since outdated profiles are also being gradually removed from the Peppol network at the same time, a direct migration to the current XRechnung 3.0 version is recommended. This helps avoid rejections, delayed payments, and repeated technical adjustments.
Invoice-Portal supports you with the transition – fast, secure, and compliant.
