What is changing
On 19 November 2025 Revenue issued guidance (eBrief No. 216/25) reflecting a significant update to its interpretation of the territorial scope of Irish VAT groups. The change came into immediate effect for VAT groups formed on or after 19 November 2025.
For VAT groups in place before that date, a transitional period up to 31 December 2026 applies, with the new interpretation applying to such groups from 1 January 2027 onwards.
The change, in short, is that an Irish VAT group is interpreted as including only the Irish establishment of members of the group, with any foreign establishments of VAT group members no longer being part of the Irish VAT group.
As a result, any supplies between the Irish VAT group and foreign establishments of the VAT group’s members are no longer disregarded for Irish VAT purposes.
Furthermore, where an entity having an establishment in a VAT group in another EU Member State also has an Irish establishment (whether in an Irish VAT group or not), supplies between that other establishment and the Irish establishment are also no longer disregarded in Ireland under the new interpretation.
This change could therefore have a significant financial and operational impact for groups with supplies between establishments of the same entity (e.g. head office to branch, branch to head office, or branch to branch) where that entity is a member of a VAT group in Ireland or in another EU Member State.
This is particularly pertinent for businesses with no or partial VAT recovery on costs (e.g. financial services and insurance institutions), as VAT charges on those intra-entity supplies will likely result in additional VAT costs.
There may, however, also be some additional VAT recovery entitlement where taxable supplies are made by the Irish establishment to its foreign establishments.
Coincidentally, shortly after Revenue announced its change of interpretation regarding the territorial scope of VAT grouping in Ireland, HMRC announced a change to its interpretation of UK VAT groups.
As the UK is no longer bound by the jurisprudence of the Court of Justice of the European Union (CJEU), HMRC has taken the opposite view to that now applied in Ireland and most of the EU.
A UK VAT group is now deemed to include any overseas establishments of UK VAT group members, regardless of how the VAT group rules are applied in the overseas jurisdiction. This emphasises the importance of considering the overall position with potentially different approaches across jurisdictions.
