Ireland's e-Invoicing Mandate: What SMEs Need to Know Before 2028
E-Invoicing Is Coming to Ireland
Ireland’s VAT Modernisation programme is one of the most significant changes to Irish business compliance in decades. Starting November 2028, large corporates must issue structured e-invoices. By 2030, every VAT-registered business in Ireland will need to comply.
If you run an Irish SME, now is the time to understand what’s coming and start preparing.
The Timeline
Phase One: November 2028
Large corporates (as defined by Revenue’s Large Corporates Division) must begin issuing structured e-invoices for all domestic B2B transactions. Crucially, all businesses must be technically capable of receiving e-invoices — even if you’re not yet required to issue them.
Phase Two: November 2029
The obligation to issue e-invoices extends to all remaining VAT-registered businesses engaged in intra-community supplies.
Phase Three: July 2030
Full compliance with the EU’s ViDA (VAT in the Digital Age) Directive, including cross-border B2B e-invoicing.
What Does “Structured e-Invoice” Mean?
No more PDFs. E-invoices must be in XML format following the EN 16931 European standard, transmitted via the Peppol network. This means your accounting software needs to generate machine-readable invoices, not just printable documents.
Why This Matters for Irish SMEs
You Need to Receive e-Invoices by 2028
Even if your business is small, you must be able to receive and process structured e-invoices from November 2028. If a large corporate sends you an e-invoice, you need software that can handle it.
Revenue Will See Everything in Real Time
The mandate includes real-time transaction reporting to Revenue. This means your VAT returns will essentially be pre-populated — but it also means errors will be spotted immediately.
The VAT Gap
Ireland’s estimated EUR 1.7 billion VAT gap is a key driver of this initiative. Revenue wants to close the gap through digital reporting, which means more scrutiny on every transaction.
