Ireland has moved its VAT-modernisation programme from policy design into the legislative process. Finance (No. 2) Bill 2026, published on 19 October 2026, proposes amendments to the Value-Added Tax Consolidation Act 2010 to establish structured domestic e-invoicing and real-time digital VAT reporting. Revenue’s implementation paper, published on 21 October 2026, confirms that the phased timetable announced in October 2025 is unchanged.
Phase One starts on 1 November 2028. VAT-registered businesses whose tax affairs are managed by Revenue’s Large Corporates Division on 1 January 2027, and that are established or have a fixed establishment in Ireland, will be required to issue structured e-invoices for taxable domestic supplies to Irish businesses and public bodies. They must also report a subset of the invoice data to Revenue in real time. Revenue estimates that approximately 2,400 businesses will fall within this first phase. From the same date, all businesses in Ireland must be able to receive structured e-invoices from Irish suppliers.
Phase Two begins on 1 November 2029. It extends the domestic issuance and reporting requirements to Irish-established VAT-registered businesses engaged in intra-EU trade, as well as businesses administered by the Large Corporates Division on 1 January 2028. Phase Three begins on 1 July 2030, when the EU VAT in the Digital Age requirements become mandatory for cross-border EU B2B transactions.
An e-invoice must be a structured, machine-readable file compliant with European Standard EN 16931-1. Scanned paper invoices, Word documents and PDFs sent by email will not satisfy the Irish requirements for in-scope supplies from November 2028. Digital reporting will transmit selected invoice data when the invoice is issued. VAT rates, payment obligations, the calculation of VAT liability and the periodic VAT3 return remain unchanged. The VIES recapitulative statement is expected to be removed from July 2030.
Revenue has launched an eInvoicing Hub containing guidance, an interactive guide and draft implementing regulations. The draft regulations address Peppol, data transmission and data requirements. Peppol is intended to be the default network for exchanging e-invoices and the mandatory channel for reporting transaction data to Revenue. Revenue also intends to become Ireland’s designated Peppol Authority from 1 January 2027.
Businesses in the first phase can begin reviewing invoice processes, data quality, customer and supplier identifiers, ERP integration and service-provider readiness. Revenue advises against locking down final system builds before the technical specifications are published. The Bill remains subject to the legislative process and the draft regulations may change before finalisation.

Ireland Updates E-Invoicing Requirements and Timeline
- Ireland will roll out mandatory structured e-invoicing and real-time VAT digital reporting in phases: 1 November 2028 for large domestic corporates, 1 November 2029 for additional VAT-registered businesses/intra-EU traders, and 1 July 2030 for cross-border EU B2B transactions under ViDA.
- From 1 November 2028, all businesses in Ireland, including public bodies, must be able to receive structured e-invoices.
- E-invoices must use the EU standard EN 16931-1; PDF invoices and other unstructured formats will not qualify.
- Peppol will be the default exchange network and mandatory reporting channel to Revenue, using a five-corner model with invoice data sent to Revenue through a Peppol provider when issued.
- For domestic transactions, reporting obligations fall on suppliers (with third-party providers allowed to transmit data); for cross-border EU transactions, separate supplier and customer reporting obligations will apply under ViDA.
