Ireland's Finance (No. 2) Bill 2026 would mandate structured e-invoicing and transaction reporting from November 2028 — a bill, not yet law

What changed in detail

This is not law. Section 51 of the Finance (No. 2) Bill 2026 (Bill 98 of 2026), as initiated, has not been passed by the Oireachtas, and its figures and dates may be amended.

As initiated, section 51 inserts a new section 66A and a new Chapter 6A into the VAT Consolidation Act 2010, with effect from 1 January 2027. Section 66A would require a ‘specified person’ to issue invoices in a structured electronic format (EN 16931 / Directive 2014/55/EU syntax) for domestic B2B and B2G supplies. The requirement would apply from 1 November 2028 to 31 October 2029 to accountable persons established in the State whose tax affairs were administered by Revenue’s Large Corporates Division on 1 January 2027. From 1 November 2029 it would also apply to those administered by that division on 1 January 2028 or engaged in intra-Community acquisitions or supplies of goods or services. Other accountable persons may issue structured e-invoices.

Chapter 6A, from 1 November 2028, would require specified persons to transmit specified transaction data to Revenue when the invoice is issued, and customers self-billing under section 71 to transmit within 5 days. Data content, formats and invoice particulars are left to regulations.

What it means

The timetable is a phased start, with the largest taxpayers first, so the first live date is more than two years away. Large Corporates Division customers should treat the bill as a planning signal and map invoicing and ERP data to EN 16931 and per-transaction reporting, while watching committee-stage amendments and the Revenue regulations that will set the detailed content.
