Ireland Confirms Phase One of VAT Modernisation: E-Invoicing for Large Corporates from November 2028
Irish Revenue has confirmed which businesses fall under Phase One of its VAT Modernisation programme: large corporates managed by Revenue's Large Corporates Division must issue e-invoices and report transaction data from 1 November 2028. Two further phases extend the mandate through July 2030.
Revenue (the Irish tax authority) has confirmed the scope of Phase One of Ireland's VAT Modernisation programme, the domestic implementation of the EU's ViDA (VAT in the Digital Age) requirements. Following its October 2025 policy paper, Revenue published a press release on 10 February 2026 naming exactly who is in scope for the first phase.
Phase One: Large Corporates, from 1 November 2028
From 1 November 2028, VAT-registered large corporates must:
- Issue EN 16931-compliant structured e-invoices for domestic B2B transactions
- Report a subset of the relevant transaction data to Revenue
A business counts as a "large corporate" for this phase if its tax affairs are managed by Revenue's Large Corporates Division and it maintains a fixed establishment in Ireland. Separately, from the same date, every VAT-registered business in Ireland — regardless of size — must be able to receive structured e-invoices, even if it is not yet required to issue them.
The Full Three-Phase Rollout
| Phase | Date | Who | What's required |
| Phase 1 | 1 November 2028 | Large corporates (Large Corporates Division) | Issue e-invoices + report data for domestic B2B; all businesses must be able to receive e-invoices |
| Phase 2 | November 2029 | All VAT-registered businesses trading intra-EU | Send and receive structured e-invoices for intra-EU B2B |
| Phase 3 | 1 July 2030 | All VAT-registered businesses | Full ViDA cross-border Digital Reporting Requirements apply |
Format and Network
Invoices must comply with EN 16931 — the same semantic standard behind XRechnung, FatturaPA, and Factur-X — so businesses already compliant with another EU country's mandate are not starting from zero. Ireland is expected to build on Peppol, which the Office of Government Procurement already operates as the national authority for B2G e-invoicing, extending it to the B2B space rather than building a separate clearance system like Italy's SDI.
Why This Matters Even If You're Not "Large"
2028 sounds distant, but the receiving obligation applies to every VAT-registered business from day one of Phase One — not just large corporates. If you invoice or get invoiced by a large corporate customer or supplier in Ireland, you'll need a system capable of receiving a structured e-invoice by November 2028, even before your own issuing obligation arrives.
