Real-Time VAT Reporting in Ireland: What Happens to Your VAT3

staxo team, 2026-09-30

Real-time VAT reporting in Ireland begins on 1 November 2028. From that date, large corporates must issue e-invoices to Irish business customers and send a subset of the data from each invoice to Revenue, according to Revenue's press release of 10 February 2026, Revenue confirms large corporates for Phase One of VAT Modernisation. The same release says every business in Ireland must be able to receive structured e-invoices from that date, even if it does not yet have to issue them.

For the VAT3 itself, very little has been decided. Revenue says tax rates, payment requirements and liability calculations stay as they are, and none of the modernisation publications we reviewed up to 29 September 2026 announces a new VAT3 cycle or a pre-filled return. The change is in timing: for businesses in scope, Revenue will see invoice data as each invoice is issued, alongside the period totals it already gets on the VAT3.

That shift is why people ask whether Revenue will pre-fill the VAT3. Respondents to Revenue's consultation asked for it, and Italy has offered pre-filled VAT drafts since 2021. This guide covers what Revenue has said, what the VAT3, RTD and VIES look like today, and what to do before the technical specifications arrive.

What real-time VAT reporting in Ireland means

Ireland's VAT system still runs on periodic returns. Revenue calls the programme the biggest change since VAT arrived over 50 years ago, and says the current reporting system is largely unchanged since 1972, in its plan VAT Modernisation: Implementation of eInvoicing in Ireland. Today you total your sales and purchases, put the figures on a VAT3, and Revenue sees the detail only if it asks.

Real-time reporting turns each invoice into a record Revenue receives close to the moment it is issued. That only works if the invoice is machine-readable. Revenue defines an eInvoice as one issued, transmitted and received in a structured format compliant with EN 16931, and its page Large corporates for Phase One of VAT modernisation states that PDF and scanned paper invoices do not qualify. Our guide to the EN 16931 e-invoice format in Ireland explains the structure.

Revenue's plan says the changes relate solely to invoicing and reporting. It will use existing infrastructure, including Peppol, which some Irish public bodies have used since 2019, and it is working with the Office of Government Procurement, Ireland's Peppol authority. The exact technical model for how data reaches Revenue has not been published.

What Revenue will receive, and when

Phase 1 applies to VAT-registered businesses managed by Revenue's Large Corporates Division that are established, or have a fixed establishment, in Ireland. Revenue has said it will write to each business in scope. The later phases are on Revenue's VAT Modernisation Timeline, updated on 20 July 2026, and the EU rules behind Phase 3 apply from 1 July 2030 under the European Commission's VAT in the Digital Age (ViDA) package.

Revenue's page What is VAT Modernisation? says the requirements will eventually reach all VAT-registered businesses, with no issuing date announced for firms that trade only in Ireland. Our guide to e-invoicing in Ireland for small businesses sets out the full sequence.

Phase 1 is small in headcount and large in value. Revenue's VAT Payments and Returns 2024 report shows 810 Large Corporates Division traders made 31% of VAT payments in 2024, while 180,201 Business Division traders, 93% of payers, made 30%. From November 2028, Revenue will get invoice data in close to real time from a group that accounts for almost a third of VAT payments.

Revenue says the reporting data subset will be specified later, with guidance and technical specifications published well ahead of each phase. None had appeared by 29 September 2026. For cross-border trade, ViDA fixes the timing: Accountancy Europe's VAT in the Digital Age factsheet says each in-scope transaction is reported when the invoice is issued or should have been, with 5 days where the customer self-bills.

The VAT3 today: periods, deadlines and who files what

The standard VAT3 period is two months, starting on 1 January, March, May, July, September and November. Revenue's page When VAT becomes payable says the Collector-General may authorise four-monthly returns where annual liability is €3,001 to €14,400, and six-monthly returns where it is €1 to €3,000. Returns and payments are due by the 19th of the following month, or the 23rd on ROS.

Our VAT3 deadlines for 2026 list every date, and the step-by-step guide to filing a VAT3 on ROS walks through the screens. At the end of 2024 there were 286,790 registered VAT traders, of whom 203,198 were active.

Nearly three in four traders file every two months, and they carry 91.2% of payments. Those six returns a year hold most of the administrative effort, so they are where any pre-filling would save the most time.

Two other returns sit beside the VAT3. The annual Return of Trading Details breaks your year down by rate and is due by the 23rd of the month after your accounting period ends, under Revenue's Tax and Duty Manual: VAT Return of Trading Details. Sellers to VAT-registered EU customers also file VIES statements by the 23rd of the following month, monthly where intra-EU supplies of goods exceed €50,000 in a quarter, as set out in The VIES Traders Manual.

Will the VAT3 be pre-filled?

As at 29 September 2026, Revenue has not announced a pre-filled VAT3. We found no mention of pre-populated returns on its ViDA and VAT modernisation hub, in the implementation plan or in the phase timeline. Anyone promising a pre-filled return from 2028 is going beyond what Revenue has published. The idea is still on the table, and one Member State already runs it.

What consultation respondents asked for

Revenue's consultation on real-time reporting and e-invoicing ran from 13 October 2023 to 31 January 2024, with findings published on 27 June 2024, as recorded in the press release Revenue publishes key findings from public consultation on modernising VAT. The Report on the initial Public Consultation process, Key Findings counts 1,118 valid responses, over 1,000 from businesses in the VAT net.

About 45% of business respondents clearly welcomed real-time reporting, about one third had concerns, nearly 14% wanted more information, and only 5% thought the present system suited the future. Some said VAT3 returns could usefully be fully or partly pre-filled from the real-time data, while noting that larger businesses might still reconcile a pre-filled return with their own records.

That reconciliation point applies to everyone. A pre-filled figure is Revenue's view of your invoices, and you remain responsible for the return.

How Italy pre-fills VAT drafts from e-invoice data

Italy has required B2B and B2C e-invoicing through its central Sistema di Interscambio since 1 January 2019, according to the European Commission's eInvoicing in Italy page. For transactions from 1 July 2021, the Agenzia delle Entrate began offering draft VAT registers and periodic VAT settlement drafts to about 2 million taxpayers, built from e-invoice, cross-border and daily receipts data, as its press release Comunicato stampa 8 luglio 2021: precompilata IVA explains. Drafts of the annual return followed for 2022 transactions.

The lesson is sequence. Italy collected invoice data from almost every business first and offered drafts afterwards. Ireland's Phase 1 covers large corporates only, so for most small firms Revenue is unlikely to hold enough of their own sales data to draft a full VAT3 for some time. Our comparison of EU e-invoicing mandates shows how other countries staged it.

The RTD and VIES when data flows in real time

VIES is the return with a confirmed end date. Accountancy Europe's factsheet states that recapitulative statements, known here as VIES returns, will no longer be required once ViDA reporting applies from 1 July 2030. That reporting covers intra-EU zero-rated supplies of goods, intra-EU acquisitions, and supplies under the mandatory reverse charge, including B2B services to other Member States.

Take a Kildare farm supplier selling equipment to a business customer in France. It files VIES by the 23rd after each period until 2030. If it uses the 0% arrangements for that trade, Phase 2 brings it into e-invoicing and real-time reporting from November 2029, and from 1 July 2030 the invoice data replaces the VIES statement. Our article on selling to EU customers under ViDA covers the 0% conditions.

The RTD has no announced end. Its rate-by-rate breakdown is the kind of summary invoice data could produce one day, though Revenue has said nothing about that in the documents we reviewed. Keep filing it on time.

Faster repayments and fewer queries: Revenue's stated aims

Revenue's implementation plan names two benefits for businesses: faster processing of VAT repayment claims, and a lower likelihood of compliance interventions for compliant businesses. Both are stated aims, and no target processing times have been published.

If Revenue already holds the invoices behind a repayment claim, it has less reason to ask for them. The Kildare supplier, zero-rating much of its output while reclaiming VAT on stock, would feel that most. Ireland starts from a strong base: Revenue's 2024 report puts the 2022 VAT compliance gap at 1.6%, about €302 million, against an EU average of 7.0%.

What changes in a Dublin café's VAT routine

Picture a café in Dublin 8 run as a limited company, filing a two-monthly VAT3 on ROS. Since 1 July 2026 its food and drink served as part of a catering service, other than alcohol, bottled water and soft drinks, carries 9% under Revenue's Finance Act 2025: VAT notes for guidance. Our guide to starting a business in Dublin covers the local supports open to firms like it.

• Until 31 October 2028. Supplier invoices keep arriving as PDFs or paper, and the VAT3 is filed by the 23rd as now.
• From 1 November 2028. The café must be able to receive e-invoices. If a national food distributor it buys from is in Phase 1, those invoices arrive as structured data, and Revenue receives a subset of the same data.
• Its own sales. It sells mostly to consumers and only in Ireland, so it has no date to start issuing e-invoices.
• The VAT3. It prepares the return from its own records. Revenue would see some of its purchases through a supplier's reports, and none of its till sales.

The practical gain is on the purchase side. Software can read structured invoices without retyping, so input VAT is keyed correctly and the reconciliation before each VAT3 is cleaner.

What to do now, before the specifications arrive

1. Confirm your VAT3 frequency and deadlines on ROS, and note the RTD date for your year end.
2. List your main suppliers and flag large corporates that may send you e-invoices from 1 November 2028.
3. Ask your accounting software provider, in writing, how and when it will receive Peppol e-invoices.
4. Record customer and supplier VAT numbers and the VAT rate on every invoice line.
5. Reconcile each VAT3 to your records before filing, the same check you would run on a pre-filled return.
6. If you sell to EU businesses, diary November 2029 and 1 July 2030, and keep filing VIES until then.
7. Keep VAT records for six years, as Revenue's page How long do you keep records for? requires.
8. Watch for Revenue's specifications and send questions to vatmodernisation@revenue.ie, the mailbox named in its February 2026 press release.

Keeping invoices, bills and VAT3 figures in one system, such as staxo, means there is one place to set up when receiving starts in 2028. It also makes step 5 a short job each period.

Real-time reporting will change what Revenue sees well before it changes what you file. Keep your VAT3 routine tight, be ready to receive e-invoices by 1 November 2028, and prepare each return from clean records with the staxo VAT3 tools.
