E-invoicing in Ireland means issuing, transmitting, and receiving invoices in a structured electronic format (machine-readable XML) that accounting and tax systems can automatically process. PDFs and scanned paper invoices are not considered e-invoices.

Ireland follows the European standard EN 16931, usually implemented as Peppol BIS Billing 3.0 XML and exchanged via the Peppol network.

Governance is shared between:

• Office of Government Procurement (OGP): Irish Peppol Authority since 18 January 2018, responsible for technical infrastructure and public sector Peppol access.
• Revenue Commissioners: Lead the VAT Modernisation programme, the 2028 mandate, digital reporting, and overall policy.

What is B2B e-Invoicing in Ireland?

B2B e-invoicing is currently voluntary (with recipient consent). It becomes phased mandatory from 1 November 2028.

• From 1 November 2028: Large corporates (defined administratively by Revenue’s Large Corporates Division) must issue structured e-invoices for domestic B2B transactions and report selected data to Revenue. All businesses must be able to receive structured e-invoices.
• From 1 November 2029: Issuance obligation extends to all VAT-registered businesses engaged in intra-Community B2B trade.
• From 1 July 2030: Full ViDA rules apply to all cross-border intra-Community B2B supplies.

What is B2G e-Invoicing in Ireland?

Public bodies have a receipt-only obligation:

• Central government since 18 April 2019
• Sub-central authorities (local government, health, education) since 18 April 2020

Suppliers to public bodies are not required to issue e-invoices unless the contract specifies it. All public bodies must accept EN 16931 invoices via Peppol.

What is B2C e-Invoicing in Ireland?

There is no mandate and none planned. Consumers can receive paper, PDF, or (with consent) structured e-invoices. VAT Modernisation is a B2B programme only. Businesses mainly engaged in B2C are subject only to the universal receive-side obligation from November 2028.

Key 2026 Updates

On 10 February 2026, Revenue confirmed:

• “Large corporate” is an administrative definition (tax affairs managed by Large Corporates Division), not based on turnover or headcount.
• Revenue will write individually to affected businesses.
• The receive-side obligation is universal from 1 November 2028 for all VAT-registered businesses.

Revenue is currently working on legislation, technical specifications, and stakeholder engagement (contact: vatmodernisation@revenue.ie).

How to Generate E-Invoices

Businesses can:

• Use a certified Peppol Access Point (recommended for most)

Under the 2028 mandate, invoices are generated in Peppol BIS 3.0 XML, routed via Peppol, and selected data is reported to Revenue.
