Updated 25 September 2026. Ireland has a timetable but no obligation yet. Revenue's roadmap of October 2025 phases in e-invoicing and real-time reporting from November 2028, which leaves Irish accounting practices two years to get supplier-invoice capture onto structured lines. This page covers the roadmap, the VAT rates, the rules on emailing firms about it, and what Invoreg does with Irish invoices today.
Is e-invoicing mandatory in Ireland in 2026?
No. There is no domestic B2B or B2G e-invoicing obligation in Ireland in 2026; public bodies can receive Peppol invoices but suppliers are not required to send them. Revenue published its VAT modernisation roadmap on 8 October 2025, setting the first mandatory phase for November 2028.
When does the B2B mandate start in Ireland?
November 2028 for large VAT-registered corporates on domestic B2B transactions, then November 2029 for all VAT-registered businesses engaged in intra-EU B2B trade, with full ViDA obligations for cross-border EU transactions from 1 July 2030. Revenue's stated aim is to "learn from early adopters and prepare systematically in advance of 1 July 2030".
Which format and platform will Ireland use?
Peppol. The roadmap says Ireland will "leverage the PEPPOL framework for secure and standardized e-invoice exchange", so a Peppol BIS document over the Peppol network is the working assumption, with the detailed specification still to come. Invoice Navigator's deadline tracker lists the same phases, with micro companies joining by 1 July 2030.
Is B2B email outreach allowed in Ireland?
Yes, on an opt-out basis. Regulation 13(4) of the ePrivacy Regulations, S.I. 336 of 2011, prohibits unsolicited marketing email to a subscriber "other than a natural person" only where that subscriber "has notified the person that the subscriber or user does not consent". Emails to a firm's generic address are therefore permitted until it objects; emails to a named individual's address are treated differently.
Which VAT rates apply in Ireland and how does Invoreg map them?
23 % standard, 13.5 % and 9 % reduced, 4.8 % on livestock, plus zero-rated and exempt supplies. Invoreg reads the rate on each line and maps it to the tax code you have configured in your accounting software, including reverse-charge codes for services bought from the UK or the EU. Ireland's VAT compliance gap was 8.3 % in 2023, against an EU average of 9.5 %.
What should an accounting firm in Ireland do now?
Get supplier invoices into your accounting software as lines, not totals, and let duplicate detection run across the client base. The large-corporate phase in November 2028 is close enough that clients will ask their accountant to lead, and a practice already posting line-level data will have most of the reporting fields the 2029 phase asks for.
