Ireland's Revenue has confirmed that large corporates will be required to issue structured e‑invoices for domestic B2B transactions from 1 November 2028, as part of the phased rollout of the EU ViDa e‑invoicing and real‑time reporting initiative. The regime will expand to all cross‑border EU B2B transactions benefiting from 0% VAT in Phase Two (November 2029) and to all cross‑border B2B transactions under the EU directive from 1 July 2030.

The OECD’s 2026 report outlines guidance on Digital Continuous Transactional Reporting (DCTR), urging jurisdictions to adopt real‑time VAT transaction reporting and structured e‑invoicing. It highlights the EU’s ViDA initiative, slated for rollout by 2030, and the requirement for intra‑EU invoicing interoperability by 2035. Businesses are advised to modernise ERP and billing systems, improve data quality, and strengthen security to meet the forthcoming digital compliance landscape.
