VAT Modernisation: Implementation of e-invoicing in Ireland

On 8 October 2025, the Revenue released a publication, “VAT Modernisation:Implementation of e-invoicing in Ireland”, setting out details of the work it is undertaking to prepare for the implementation of the EU’s VAT in the Digital Age (ViDA) requirements, an initiative to modernise EU VAT systems to better support how businesses trade, while bolstering the fight against VAT fraud. The publication is effectively a roadmap for the introduction of domestic e-invoicing and real-time reporting in Ireland.

The introduction of a domestic e-invoicing scheme in Ireland represents an important milestone in the modernisation of the Irish VAT system and will have a significant impact on Irish businesses.

Under the new arrangements, affected businesses will be obliged to issue structured electronic invoices to their customers, with key transaction details reported to Revenue in real-time.

There will be a three-phase implementation timeline to provide businesses sufficient preparation time and to give the Revenue adequate time to learn from early adopters and prepare systematically in advance of 1 July 2030, the date the EU ViDA requirements for e-invoicing and real-time reporting become mandatory.

Phase 1 – November 2028: VAT-registered large corporates will be required to implement e-invoicing and real-time reporting for domestic B2B transactions.

Phase 2 – November 2029: Domestic B2B e-invoicing and real-time reporting will be extended to all VAT-registered businesses engaged in intra-EU B2B trade.

Phase 3 – July 2030: Full implementation of EU ViDA requirements for all cross-border EU B2B transactions becomes mandatory in all 27 EU Member States. As such, all Irish VAT-registered businesses already operating under the domestic system will transition to meet these EU obligations.

As e-invoicing is an end-to-end digital process, for the system to operate effectively, all businesses will need to be able to receive e-invoices, regardless of whether they are obligated to issue them. This means that even if businesses are not yet required to issue e-invoices under the phased rollout, businesses need to have the capability to receive them in the required structured electronic format.

Although there is a proposed 3-year lead in time, as the transition to mandatory e-Invoicing will require significant time and resource investment, businesses need to start familiarising themselves with the measures so they can assess the impact. Such changes will involve
numerous parts of a business including tax, finance, IT, procurement etc.

Businesses should begin to act now to prepare by reviewing their ERP systems and / or invoicing software to determine the extent to which existing systems will be able to cope with the new digital requirements or whether additional tools / add-ons are required.
