Summary

• New standard adopted: CEN has unanimously approved the revised European eInvoicing semantic standard EN 16931‑1:2026, with 17 Member States voting in favour and no objections raised. [ec.europa.eu]
• ViDA‑aligned revision: The update reflects VAT in the Digital Age (ViDA) requirements, notably to support structured eInvoicing and automated VAT reporting for future EU‑wide digital reporting obligations. [ec.europa.eu]
• Implementation phase begins: The Definitive Text was released on 18 March 2026, and national standardisation bodies will now publish the standard domestically, alongside forthcoming CEN implementation guidance. [ec.europa.eu]

Article

The European Committee for Standardisation (CEN) has formally approved a major revision of the European eInvoicing standard, adopting EN 16931‑1:2026 as the new reference for the semantic data model of electronic invoices. The decision was taken following a formal vote in which representatives of the National Standardisation Bodies of 17 EU Member States participated and unanimously supported the revision, while the remaining Member States abstained without raising any objections. [ec.europa.eu]

The revised standard replaces the previous EN 16931‑1:2017 version and represents a significant milestone in the evolution of European eInvoicing. While the original standard was primarily designed to support B2G eInvoicing under Directive 2014/55/EU, the 2026 revision expands and refines the semantic model to better accommodate complex B2B invoicing scenarios and future‑proof the standard for EU‑wide digital VAT reporting obligations.

A key driver behind the revision is the EU’s VAT in the Digital Age (ViDA) initiative. The updated EN 16931‑1 introduces enhanced and clarified data structures that enable invoices to function not only as commercial documents but also as reliable, machine‑readable data sources for automated VAT controls and digital reporting requirements. This evolution is essential in light of the Commission’s plan to introduce mandatory structured eInvoicing and near real‑time reporting for intra‑EU B2B transactions by 2030.

CEN confirmed that the Definitive Text of EN 16931‑1:2026 was made available on 18 March 2026, marking the completion of the drafting process and its formal distribution to national standardisation bodies. The European Commission is expected to publish the official reference to the new standard in the Official Journal of the EU, together with a transition period allowing Member States and market participants time to migrate from earlier versions. [ec.europa.eu]

As next steps, national standardisation bodies will proceed with the announcement and national publication phases, ensuring that EN 16931‑1:2026 becomes available as a national standard across the EU. In parallel, CEN is preparing a guidance document containing practical examples to support implementers in applying more complex invoicing requirements under the revised semantic model, facilitating consistent and interoperable implementation across jurisdictions.

Access to the Standard

The EN 16931‑1:2026 standard itself is published by national standardisation bodies and is generally available for purchase. For example:

• BSI (UK): BS EN 16931‑1:2026 – Electronic invoicing – Semantic data model of the core elements of an electronic invoice (available here). [knowledge….igroup.com]

Other national standards bodies (e.g. DIN, AFNOR, NBN) will publish their national equivalents in the coming weeks.
