Ireland reconfirms mandatory B2B e-invoicing

Ireland has once again put its VAT digitalisation plans in the spotlight, reconfirming a phased rollout of mandatory domestic B2B e-invoicingElectronic invoicing - widely referred to as e-invoicing - is the exchange of a digital document between a supplier and a buyer. E-invoices are issued, transmitted and received in a structured data format that enabled automatic and electronic processing. They contain data in a machine-readable format so that an AP system can read an invoice without manual data entry, leading to faster and more efficient invoicing. and real-time VAT reporting. This update follows the public consultation on modernising Ireland’s VAT system and builds on the EU’s wider VAT in the Digital Age (ViDAViDA or 'VAT in the Digital Age', is an EU initiative proposed by the European Commission that seeks to modernise and harmonise VAT processes for member states, by embracing new technologies. It is aimed at updating processes for the management of VAT, and reduce the VAT gap and fraud. The proposal also aims to address challenges in the area of VAT raised by the development of the platform economy.) initiative – aimed at bringing VAT reporting into the digital era across the European Union.

What’s been confirmed

On the 10th February, the Irish Revenue Commissioners reconfirmed its plans for a phased introduction of mandatory e-invoicing and VAT reporting:

1. November 2028 – Large VAT-registered corporates must implement e-invoicing and real-time VAT reporting for domestic business-to-business transactions. All businesses must at least be able to receive structured e-invoices.

2. November 2029 – The requirement expands to all VAT-registered businesses engaged in domestic transactions and intra-EU business-to-business trade.

3. July 2030 – Full compliance with the EU’s ViDA Directive, which mandates structured e-invoicing and reporting for cross-border EU B2B transactions.

Who is in scope for phase 1?

For the November 2028 go-live, not every business will be required to issue structured e-invoices from day one. Ireland is taking a phased approach, starting with large corporates.

For the purposes of phase one, a business will be considered a large corporate if it is:

• A VAT-registered business whose tax affairs are managed by Revenue’s Large Corporates Division; and

• Established in Ireland or has a fixed establishment in Ireland.

In other words, this first wave targets the largest and most complex taxpayers – those already under the direct oversight of Revenue’s Large Corporates Division. These businesses are expected to lead the transition, setting the foundation for broader adoption in 2029 and beyond.

All VAT-registered businesses, however, must at least be capable of receiving structured e-invoices by November 2028 – even if they are not yet required to issue them.

What will the Irish model look like?

As expected, Ireland’s regime will align with the EU’s EN 16931 structured e-invoicing standard – the same core standard underpinning e-invoicing reforms across Europe under the ViDA framework.

The exchange model will be based on the PEPPOLThe Pan-European Public Procurement On-Line simplifies electronic procurement by developing technology standards that can be implemented by all governments across the EU. network, using the established five-corner model. In practice, this means:

• Businesses exchange invoices in a structured XMLExtensible Markup Language is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. format, not PDFs.
• Each business connects via an accredited PEPPOL Access Point provider.
• Invoice data is transmitted securely between sender and recipient through certified intermediaries.
• Structured data enables automated validation, processing, and (eventually) real-time or near real-time reporting to Revenue.

This is a significant shift from traditional invoice exchange. The focus moves from document sharing to data interoperability, allowing tax authorities to receive transaction-level information directly and reducing reliance on periodic VAT returns alone.

For many organisations, this will require upgrades to ERPEnterprise resource planning (ERP) is a type of software that organisations use to manage main business processes. systems, integration with PEPPOL Access Points, and careful review of master data and VAT determination logic.
