Introduction
To align Ireland's VAT grouping rules more closely with EU principles, Revenue has changed how Irish VAT groups operate. The immediate practical effect is that Irish VAT grouping is now limited to Irish-established entities. Overseas branches and head offices are no longer treated as part of the Irish VAT group.
As a result, cross-border transactions between an Irish VAT group and an overseas branch or head office may now fall within the scope of VAT, even where they were previously disregarded. This includes internal service charges, management fees, cost allocations and certain transfer pricing ("TP") adjustments.
Revenue announced the change in November 2025 and introduced a transitional period until 31 December 2026, giving affected businesses time to assess the impact and adapt their arrangements. Many organisations are now moving from initial impact assessments to implementation planning.
While the legal principles are increasingly well understood, the practical exercise of identifying affected transactions, quantifying the VAT impact and determining the appropriate response is proving more complex than many businesses anticipated. Those that begin the process early will have greater flexibility to address risks, manage VAT costs and consider alternative operating models where appropriate.
The background
Revenue's revised approach is based on principles established by the Court of Justice of the European Union ("CJEU") in the Skandia (C-7/13) and Danske Bank (C-812/19) decisions. In both cases, the CJEU concluded that a VAT group and an overseas branch or head office of the same legal entity may be treated as separate taxable persons for VAT purposes.
In Skandia, services supplied by a US head office to its Swedish branch were treated as supplied to the Swedish VAT group of which the branch formed part. In Danske Bank, the Court confirmed the same principle in reverse, where a Danish VAT-grouped head office supplied services to its Swedish branch.
Revenue's revised approach brings Ireland into line with these EU principles and removes a position on which some businesses had historically relied, namely that certain dealings between an Irish VAT group and its overseas head office or branch fell outside the scope of VAT altogether.
Why this matters for financial services businesses
The changes are particularly relevant for financial services businesses, including banks, insurers, investment managers, funds and structured finance vehicles. These businesses frequently operate through a combination of Irish and overseas establishments and often have restricted VAT recovery.
Internal cross-border transactions may now need to be analysed in the same way as third-party supplies, including consideration of the nature of the services provided, where they are supplied for VAT purposes and whether any resulting VAT can be recovered.
The outcome will vary significantly between businesses. In some cases, additional taxable transactions may improve VAT recovery. In others, newly VATable costs may give rise to irrecoverable VAT and therefore a permanent cost. Existing VAT recovery methodologies may also need to be revisited where newly recognised transaction flows distort historic recovery rates or no longer produce a fair and reasonable result.
Four areas to focus on now
Map affected transactions and review the operating model
The starting point is to identify all cross-border transactions that may now be affected by the revised rules. This includes transactions that were previously disregarded because they arose between a head office and its own branch.
Once affected flows have been identified, businesses should consider whether their existing operating model remains appropriate. This may involve reviewing how functions are allocated across jurisdictions, whether activities should be centralised or decentralised, and whether existing branch structures remain fit for purpose in light of the VAT consequences.
Look beyond invoices and review transfer pricing arrangements
A review should not be limited to formal service invoices and intercompany recharges. Transfer pricing adjustments, management fees, cost allocations and year-end true-ups should also be considered.
Recent CJEU developments in Arcomet and Stellantis reinforce the importance of determining whether intra-group charges reflect identifiable supplies for VAT purposes and whether the pricing aligns with the economic reality of what is being provided. In practice, TP adjustments should form part of the broader VAT mapping exercise rather than being viewed solely as direct tax matters.
For businesses with restricted VAT recovery, the stakes can be significant. If a TP-driven charge is treated as consideration for a taxable supply, any VAT arising may become a permanent cost.
Assess whether exemptions are available
Once relevant flows have been identified, businesses should determine whether the transactions are taxable, exempt or outside the scope of VAT.
This analysis should consider Irish VAT legislation, the EU VAT Directive, relevant CJEU case law and Revenue guidance, as well as any established administrative practice. Where exemptions are available, they may significantly reduce or eliminate the VAT cost associated with previously disregarded transactions.
Document the analysis and supporting rationale
Businesses should ensure that the analysis undertaken is fully documented. This should include the transaction mapping exercise, the VAT treatment applied to each flow, the valuation methodology utilised, any exemptions considered and the resulting VAT recovery implications.
Transfer pricing policies, intercompany agreements and cost allocation methodologies should also be reviewed and updated where necessary to ensure consistency with the VAT position adopted. Maintaining a robust audit trail will be important both during the transition period and in the event of future Revenue enquiries.
Taking action
These changes should not be viewed as a standalone VAT grouping exercise. For many organisations, the implications extend beyond indirect tax and into broader questions around operating model, governance, transfer pricing and organisational structure.
The immediate priority is to identify affected transactions, assess whether VAT applies, quantify the impact on VAT recovery and determine whether changes to structure, documentation or compliance processes are required. Businesses that begin this work early will be better positioned to manage risk, preserve available VAT efficiencies and avoid implementation challenges as the transition period comes to an end.
