Ireland’s Revenue has confirmed that Peppol will be the default network for exchanging structured e-invoices and the mandatory channel for reporting invoice data to the tax authority under its VAT Modernisation programme.

The detail appears in Revenue’s VAT Modernisation: Implementation of eInvoicing in Ireland – 2026 Update, published on 21 October. The paper explains how the proposed legislation will work in practice, while retaining the phased rollout announced in October 2025.

The Finance Bill (No. 2) 2026 provides the legislative foundation through proposed amendments to the Value-Added Tax Consolidation Act 2010. Its provisions remain subject to the legislative process, and supporting regulations are currently in draft form.

Peppol for Reporting, With Flexibility for Invoice Exchange

Under the proposed approach, suppliers and customers may agree to exchange invoices through an alternative network or routing method. "Regulations will specify Peppol as the default transmission method, unless both parties to a transaction have agreed to use a different routing method." However, suppliers subject to digital reporting will still need to transmit the required data to Revenue through a Peppol service provider.

Revenue describes a five-corner model: the supplier’s service provider checks and transmits the structured invoice to the customer’s provider, while reporting a specified subset of invoice data to Revenue when the invoice is issued.

Invoices must comply with the European standard EN 16931-1. Revenue will publish the detailed validation rules and reporting requirements in technical specifications.

Rollout Dates Unchanged, Scope Clarified

The update provides more precise criteria for identifying affected businesses:


  • 1 November 2028: Approximately 2,400 VAT-registered large corporates must begin domestic e-invoicing and real-time reporting. Phase One covers businesses established, or with a fixed establishment, in Ireland whose tax affairs are administered by Revenue’s Large Corporates Division on 1 January 2027.
  • 1 November 2029: Domestic obligations extend to Irish-established VAT-registered businesses engaged in intra-EU trade in goods or services, alongside additional businesses administered by the Large Corporates Division on 1 January 2028.
  • 1 July 2030: EU VAT in the Digital Age requirements apply to cross-border EU B2B transactions.

All businesses in Ireland, including public bodies, must be able to receive e-invoices from 1 November 2028, even where they are not required to issue them. For invoices within scope, customers will no longer be able to insist on receiving a PDF.

Revenue also plans to provide business identifiers during 2027. VAT-registered businesses will use their existing VAT numbers; businesses without a VAT registration will receive a separate identifier.

Planning Can Begin Before Specifications Are Finalised

Revenue advises affected issuers to map invoice flows, review customer and supplier data, and discuss readiness with accounting and ERP providers. Final system builds should wait until regulations and technical specifications are published.

Businesses whose only obligation is to receive e-invoices do not need to act immediately, according to Revenue. Further guidance will follow through its new eInvoicing Hub.

Revenue also intends to take over as Ireland’s Peppol Authority from the Office of Government Procurement on 1 January 2027.

The changes will introduce transaction-level reporting, but periodic VAT returns will remain. VAT rates, payment obligations and the calculation of VAT liability are unchanged.
