Key takeaways
- Mandatory e-invoicing and real-time reporting start on 1 November 2028 for large corporates managed by Revenue's Large Corporates Division and established in Ireland.
- All businesses in Ireland must be able to receive e-invoices from 1 November 2028.
- Phase 2 on 1 November 2029 adds businesses in zero-rated intra-EU B2B trade; EU ViDA rules follow in July 2030.
- E-invoices must comply with EN 16931, and Peppol will be the default network and the channel for reporting.
- The Finance (No. 2) Bill 2026 adds sections 66A and 83A to the VAT Act, effective 1 November 2028, but is not yet law.
In short: Ireland e-invoicing becomes mandatory in phases. From 1 November 2028, large corporates managed by Revenue's Large Corporates Division must issue e-invoices for domestic B2B sales and report invoice data to Revenue in real time. From then, every business in Ireland must be able to receive e-invoices. Wider phases follow in November 2029 and July 2030.
Updated October 2026. This guide reflects the Finance (No. 2) Bill 2026 published on 19 October 2026 and Revenue's VAT Modernisation pages updated on 20 October 2026.
Is e-invoicing mandatory in Ireland?
Not yet, but it will be. Mandatory e-invoicing and digital VAT reporting start on 1 November 2028 for the largest businesses, and the Finance Bill now proposes the legal basis.
Revenue calls the programme VAT Modernisation. It is Ireland's response to the EU's VAT in the Digital Age (ViDA) package, which requires e-invoicing and digital reporting for cross-border B2B trade from 1 July 2030 (European Commission). Ireland is moving earlier for domestic trade. Read our overview of the ViDA package for the EU background.
An e-invoice is not a PDF. Revenue says an e-invoice is issued, sent and received in a structured electronic format that allows automated processing, and that PDFs and scanned paper invoices do not meet the requirement (Revenue: Large corporates).
What does the Finance Bill 2026 actually do?
The Finance (No. 2) Bill 2026 inserts new rules into the VAT Consolidation Act 2010 for structured e-invoices and VAT digital reporting. According to the Explanatory Memorandum, these rules take effect from 1 November 2028.
The Department of Finance published the Bill and its Explanatory Memorandum on 19 October 2026 (Department of Finance: Finance (No. 2) Bill 2026). The Explanatory Memorandum describes section 51 of the Bill as follows (Explanatory Memorandum):
- New section 66A: provides for issuing invoices or other documents in a structured electronic format.
- New Chapter 6A and section 83A: provide for VAT digital reporting.
- Effective date: "The new section 66A and Chapter 6A will be effective from 1 November 2028."
The Explanatory Memorandum gives a fixed date rather than a ministerial commencement order for these provisions. The Bill is still going through the Oireachtas, so the final text could change before it is signed into law. The Explanatory Memorandum does not describe any new penalties specific to e-invoicing or digital reporting.
The technical detail sits in secondary legislation. Revenue has published draft VAT regulations, effective 1 November 2028, that add a new Regulation 21A. The draft requires structured invoices to use a valid Peppol format and the Peppol network, and requires specified invoice data to reach Revenue over Peppol (Revenue: draft VAT regulations).
What is the Ireland e-invoicing timeline?
Revenue has set three phases between November 2028 and July 2030. Each phase widens the group of businesses that must issue e-invoices and report data.
| Phase | Start date | Who must issue and report | Transactions |
|---|---|---|---|
| Phase 1 | 1 November 2028 | VAT-registered large corporates managed by Revenue's Large Corporates Division on 1 January 2027, established or with a fixed establishment in Ireland | Taxable domestic B2B supplies |
| Receiving (all phases) | 1 November 2028 | All businesses in Ireland | Must be able to receive e-invoices from suppliers required to issue them |
| Phase 2 | 1 November 2029 | VAT-registered businesses in cross-border EU B2B trade with zero-rated goods, and reverse-charge services | Domestic B2B obligation extended to these businesses |
| Phase 3 | July 2030 | Businesses in all EU Member States | EU ViDA rules for all cross-border EU B2B transactions |
The phase dates come from Revenue's implementation phases page (Revenue: Implementation phases) and VAT Modernisation timeline (Revenue: VAT Modernisation timeline). Revenue says Phase 1 affects relatively few businesses.
Who is in scope for Phase 1?
Phase 1 covers a defined list of large corporates. A business is in scope if it meets all three of Revenue's conditions.
- It is VAT-registered and makes taxable supplies.
- Its tax affairs are managed by Revenue's Large Corporates Division on 1 January 2027.
- It is established, or has a fixed establishment, in Ireland.
Revenue first confirmed this definition on 10 February 2026 and said it would write to the businesses concerned (Revenue press release). Businesses moved out of the Large Corporates Division after 1 January 2027 still start on 1 November 2028. Businesses moved into it after that date, and still there on 1 January 2028, start on 1 November 2029 (Revenue: Large corporates).
What about non-resident businesses?
Revenue's Phase 1 definition only includes businesses established or with a fixed establishment in Ireland. A non-established business that is only VAT-registered in Ireland does not meet that test. Revenue has not yet published specific guidance for non-established businesses in later phases, so check with Revenue or an adviser.
Does every Irish business need to receive e-invoices in 2028?
Yes. From 1 November 2028, all businesses in Ireland must be able to receive e-invoices from any supplier required to issue them, even if they are not yet required to send them.
This is the part of the mandate that reaches small businesses first. If a large corporate supplier sends you an e-invoice, your systems need to accept and process it (Revenue: All businesses). Revenue is also introducing a Business Identifier in 2027. For VAT-registered businesses, the existing VAT number becomes the Business Identifier. Non-VAT-registered businesses will be assigned one (Revenue: Business Identifier).
What format and network will Ireland use?
Irish e-invoices must comply with the European standard EN 16931, and Peppol will be the default network. Revenue publishes the technical specifications separately.
- Standard: e-invoices must comply with EN 16931-1 (Revenue: Large corporates).
- Network: from 1 November 2028, Peppol will be the default method to transmit e-invoices, and Peppol will be mandated for reporting to Revenue (Revenue: Peppol).
- Peppol Authority: Revenue plans to take over as Ireland's Peppol Authority from the Office of Government Procurement on 1 January 2027.
- Alternatives: the draft regulations allow other structured formats or networks if supplier and customer agree in advance, but the reporting data still goes over Peppol (Revenue: draft VAT regulations).
Revenue's technical specifications page is still a placeholder. It says schemas, standards and test environments will be published before the 1 November 2028 go-live (Revenue: Technical specifications). Our guide to what Peppol is explains how access points work. Belgium uses a similar Peppol-based model, covered in our Belgium e-invoicing guide.
How does real-time VAT reporting work in Ireland?
In-scope businesses must send a subset of the data in each e-invoice to Revenue. Revenue says large corporates will do this in real time, over the Peppol network.
Revenue's Peppol page states that large corporates must "send a subset of the data contained in these eInvoices to Revenue in real time" (Revenue: Peppol). The draft regulations list different data sets for invoices and for credit and debit notes. They also allow a third party, such as a service provider, to transmit the data, while the business stays responsible for compliance (Revenue: draft VAT regulations).
The exact data fields and timing rules are not final. Do not build to a specific reporting deadline until Revenue publishes its specifications. Digital reporting sits alongside, not instead of, the regular VAT return. Our Ireland VAT manual covers return periods, and our guide to VAT rates in Ireland covers the rates that each e-invoice line will need to show.
What should businesses do now?
Large corporates have two years to prepare, and every other business has the same time to get ready to receive. Start with scope and data, then systems.
- Confirm your phase: check whether your Irish entity was managed by the Large Corporates Division on 1 January 2027, and whether it is established in Ireland.
- Map your invoice flows: separate domestic B2B sales, zero-rated intra-EU supplies, reverse-charge services and B2C sales.
- Plan to receive first: make sure accounts payable can accept EN 16931 e-invoices over Peppol by 1 November 2028.
- Check your data: confirm you hold customer VAT numbers or Business Identifiers, VAT rates and line-level detail.
- Choose a Peppol service provider: review integration with your ERP, rejected invoice handling and reporting support.
- Follow the legislation: track the Finance Bill through the Oireachtas and Revenue's final regulations and specifications.
- Prepare for 2029 and 2030: businesses with intra-EU trade should plan for Phase 2 and ViDA now, not later.
Revenue also suggests reviewing invoicing and ERP systems, checking readiness with software providers and briefing internal teams (Revenue: Large corporates).

How Taxually handles this
Taxually's e-invoicing API sends structured invoices to tax authority platforms and over the Peppol network from one integration, with Ireland reached through Peppol; Taxually is a certified Peppol Access Point. The Irish VAT returns those invoices feed into can be filed through CrossTax.
