Ireland's e-invoicing timeline
Revenue is introducing mandatory e-invoicing and real-time VAT reporting in three phases.
November 2028
Phase 1 — large corporates
VAT-registered large corporates must issue e-invoices and report key transaction data to Revenue in real time for domestic business-to-business transactions.
November 2029
Phase 2 — businesses trading across the EU
The domestic obligation extends to all VAT-registered businesses engaged in cross-border EU business-to-business trade.
July 2030
Phase 3 — EU-wide ViDA requirements
The EU's VAT in the Digital Age rules become mandatory: structured e-invoicing and digital reporting for all cross-border EU business-to-business transactions.
From the first phase, businesses that are not yet required to issue e-invoices will still need to be able to receive them in a structured electronic format.
Invoices must follow the European standard EN 16931, and Revenue plans to use existing infrastructure including the Peppol network. Issuing PDF invoices or scanned paper invoices will no longer satisfy VAT compliance requirements.
