E-Invoicing in Ireland
Discover how Descartes helps businesses prepare for Ireland's evolving e-invoicing landscape, including mandatory B2B e-invoicing and e-reporting requirements.
Preparing for
E-Invoicing?
Ireland is preparing a phased introduction to mandatory electronic invoicing and real-time VAT reporting. The first phase begins on 1 November 2028, when VAT-registered large corporates must be able to send structured e-invoices for domestic B2B transactions, and report specified data to the Revenue Commissioners.
From the same date, every business in Ireland must be able to receive structured e-invoices, including businesses that are not yet required to issue them.
| Topic | What Does the Irish E-Invoicing Mandate Mean? |
|---|---|
| Status | Businesses may issue e-invoices under existing VAT rules. Ireland’s phased mandatory domestic B2B does not start until November 2028. |
| Who is affected? | Phase One applies to VAT-registered businesses whose tax affairs are managed by Revenue’s Large Corporate Division, and that are established or have a fixed establishment in Ireland. |
| Network | Peppol is Ireland’s selected network for transmitting public-sector e-invoices, it is expected to be mandatory for B2B e-invoicing. |
| Formats | E-invoices must be sent, transmitted, and received in a structured format in compliance with the European standard EN 16931. The Irish Tax and Customs Authority (Revenue) gives XML as an example but has not yet published the completed list of syntaxes. |
| PDF invoices | PDFs, scanned paper invoices and other unstructured documents will not satisfy e-invoicing requirements. |
| B2G invoices | Irish central and sub-central public bodies must be able to receive and process EN 16931-compliant invoices. |
| B2C | The approved Irish sources do not announce a domestic B2C e-invoicing obligation. From November 2029, Ireland’s domestic obligation will first extend to VAT-registered businesses in cross-border EU B2B trade under zero-rate arrangements. |
| E-reporting | From 1 November 2028, large businesses must report relevant e-invoice data to Revenue in real time for domestic transactions. |
What Becomes Mandatory from 1 November 2028?
Ireland’s first phase combines two obligations:
E-Invoicing
VAT-registered large businesses within Phase One must send structured e-invoices to their Irish customers for B2B transactions. An e-invoice must be issued, transmitted, and received in a structured electronic format that allows automated processing and complies with EN 16931
Real-Time Reporting
Domestic e-invoicing and real-time reporting will extend to VAT-registered businesses engaged in cross-border EU B2B trade subject to zero-rate VAT
Who Must Comply in Ireland’s Phase One E-Invoicing?
For e-invoicing, Revenue defines a large corporate as a business that:
- Is registered for VAT
- Has its tax affairs managed by Revenue’s Large Corporates Division
- Is established, or has a fixed establishment, in Ireland
As mentioned above, from Phase One, every business in Ireland must be able to receive e-invoices.
Ireland’s E-Invoicing Implementation Timeline
1 November 2028: Phase One
- VAT-registered large corporates must use e-invoicing and e-reporting for domestic B2B transactions
- All businesses in Ireland must be able to receive and process e-invoices
November 2029: Phase Two
- Domestic e-invoicing and real-time reporting will extend to VAT-registered businesses engaged in cross-border EU B2B trade subject to zero-rate VAT
July 2030: Phase Three
- EU VAT in the Digital Age (ViDA) requirements will make e-invoicing and e-reporting mandatory for intra-EU B2B transactions
- Irish businesses already participating in the domestic system will transition to the EU requirements
What Businesses Should Do Now
- Determine if each Irish entity is VAT-registered, managed by Revenue’s Large Corporates Division, and established in Ireland
- Map domestic B2B, intra-EU B2B and public-sector invoice flows so that each phase can be addressed separately
- Prepare every Irish business operation to receive and process structured e-invoices by 1 November 2028
- Review invoicing, accounting and ERP systems for structured EN 16931 data support, automated processing and future reporting integration
- Engage software providers about technical readiness, required upgrades and testing plans
