E-invoicing in Ireland

Mandate plannedPeppol connectedUpdated January 2026Verified · automated check

Ireland announced a phased B2B e-invoicing mandate in October 2025. Large corporates start November 2028, cross-border EU B2B follows November 2029, and full ViDA compliance by July 2030. The country uses the Peppol network for both B2G and future B2B, with EN 16931 structured e-invoices replacing PDFs.

TL;DR

Ireland is planning e-invoicing using peppol_bis_3_0, ubl_2_1, un_cefact_cii, cius_cefact formats. Connected to the Peppol network for cross-border exchange.

Implementation notes

Peppol-based, phased approach. Ireland is building entirely on Peppol infrastructure with no national portal. The Office of Government Procurement serves as the Peppol Authority. PDFs will no longer qualify as e-invoices under the mandate — your pipeline must produce EN 16931 structured data. The first phase targets large corporates in November 2028, giving a long runway for implementation.
