E-invoicing in Ireland from 2028: what every business must do

Revenue’s published timeline sets out who is affected and when.

• November 2028: VAT-registered large corporates must issue e-invoices and adopt real-time reporting for domestic business-to-business sales.
• November 2029: the domestic obligation extends to VAT-registered businesses that trade cross-border within the EU.
• July 2030: the EU’s VAT in the Digital Age rules apply to all cross-border EU business-to-business transactions.
• All phases: every business must be able to receive and process e-invoices from any supplier that is required to issue them.

It is easy to read “large corporates” and assume a small firm can wait until 2029 or later. The receiving requirement changes that. If you supply goods or services to a large company, or buy from one, structured e-invoices will start arriving in November 2028, and your systems need to accept them.

Revenue defines a large corporate as a VAT-registered business whose tax affairs are managed by its Large Corporates Division. Revenue said in October 2026 that it would write to those businesses to confirm they are in scope.

An e-invoice here is a structured electronic file, such as XML, that follows the European standard EN16931. Revenue is explicit that unstructured formats, including PDFs and scanned paper documents, do not meet the requirement. A PDF attached to an email is an electronic invoice in everyday language, but it is not an e-invoice in this sense.

Two years is enough time if you start with simple steps.

• List your largest customers and suppliers and note which are likely to be large corporates.
• Ask your accounting software provider how it will receive and process structured e-invoices, and by when.
• Clean up supplier and customer records: VAT numbers, legal names and addresses must be accurate for structured invoices to match.
• Keep your books current, because real-time reporting rewards businesses that already record transactions as they happen.

Ask whether the product will accept EN16931 invoices directly into bills, how it will map the structured data to your accounts and VAT codes, and whether it will issue structured invoices when your business falls into a later phase. Ask for dates, not just intentions, and ask how invoices from suppliers on different e-invoicing networks will reach you. Revenue encourages businesses to work with their software providers now to ensure technical readiness.

E-invoicing gets the headlines, but the reporting that comes with it matters as much. Large corporates will send a subset of invoice data to Revenue for domestic business-to-business transactions as they happen. Over time that gives Revenue a near-live view of trade between businesses, and returns that do not match the invoice data will stand out.

For smaller businesses the lesson is the same as for every digital tax change: books that are kept current and coded consistently cost little to adapt, and books caught up once a quarter cost a great deal.

Accountants will field the same question from many clients at once over 2027 and 2028: is my software ready? Practices that standardise clients on a small number of products with a clear e-invoicing plan will spend far less time answering it than practices supporting a dozen different systems.

HelloBooks already reads supplier bills and receipts into the ledger and keeps every transaction coded with its Irish VAT treatment, which is the groundwork real-time reporting depends on. We will publish our plan for receiving and issuing structured e-invoices for Ireland well ahead of November 2028; until then, ask us, and every other provider you use, for a dated answer.
