CEN approved an updated EN 16931‑1 e‑invoicing standard on 13 February 2026, adding new mandatory fields for B2B transactions and aligning with the July 2030 Digital Reporting Requirements. The revision supports both B2B and B2G use, enabling ViDA users to comply without costly system rebuilds.

Ireland has announced a phased rollout of mandatory B2B e‑invoicing, starting with large corporates in November 2028 and culminating in full ViDA compliance by July 2030. The new system will use the PEPPOL framework and EN 16931 structured data, requiring all businesses to receive structured e‑invoices. The change aligns Ireland with the EU’s digital VAT agenda and will modernise VAT administration.
