In a decision issued on 7 May 2026, Italy’s Supreme Court rejected the Revenue Agency’s attempt to impose guarantee fee adjustments on an Italian subsidiary that provided real security to support financing obtained by its parent company. Although no fee was charged, the court held that a free intragroup guarantee is not automatically inconsistent with the arm’s length principle. Instead, the correct analysis requires an examination of the broader economic context, including any expected benefits to the guarantor.
Facts of the Case
An Italian subsidiary of a US-parented group provided security worth approximately EUR 42 million in connection with financing extended by a pool of US banks. The US parent was the actual beneficiary of the financing, and the Italian company did not charge any remuneration for providing the security. Following a tax audit, the Italian Revenue Agency determined that the overall transaction lacked valid economic reasons and that the absence of remuneration was inconsistent with Italy’s transfer pricing rules under Article 110(7) of the Income Tax Code. The tax authorities then applied the comparable uncontrolled price method using an average rate of return of 3.13% and assessed approximately EUR 1.3 million in additional taxable income per year for fiscal years 2009 and 2010.
The Italian company challenged the assessments before the Provincial Tax Commission of Turin, which rejected the challenge. The Piedmont Regional Tax Commission later reversed that decision and annulled the assessments. The Revenue Agency then appealed to the Supreme Court.
The dispute centred on a key question: must an intragroup guarantee always carry a fee, or can indirect economic benefits and commercial justifications support a zero-fee structure?
Decision of the Supreme Court
The Supreme Court held that, where a subsidiary guarantees its parent company’s obligation, remuneration may not be required if there are valid economic reasons for the transaction and the arrangement reflects an interest in the commercial success of the group. Whether such reasons exist is a question of fact reserved to the trial court. In dismissing the Revenue Agency’s appeal, the court rested its reasoning on a substantive analysis of intragroup transactions:
-
“Gratuitousness” cannot be assessed solely by reference to the isolated legal act or the absence of immediate consideration.
-
The broader economic context must be taken into account, including any indirect benefits derived by the entity granting the guarantee.
-
This approach is consistent with the doctrine of compensating advantages and EU case law permitting taxpayers to demonstrate genuine commercial reasons for the terms of cross-border related-party transactions.
The lower court had already found that the Italian subsidiary had a concrete economic interest in supporting its US parent company. Those benefits included safeguarding future revenues and, more importantly, preventing financial distress at the parent level that could jeopardise the Italian subsidiary’s own operations. Because these findings were factual, the Supreme Court could not revisit them on appeal.
BDO Perspective
The Supreme Court decision is significant but should not be read as a blanket exemption for free intragroup guarantees. The arm’s length principle continues to apply. However, accurate delineation of the transaction and demonstrable indirect benefits may justify the absence of a separate guarantee fee. This interpretation is consistent with earlier Supreme Court jurisprudence on interest-free or non-market intragroup financing, which recognises that legitimate business reasons may explain non-standard terms. Importantly, a generic reference to “group interest” is insufficient; taxpayers must demonstrate the guarantor’s own economic rationale through concrete and contemporaneous evidence.
For multinational groups, the decision makes robust documentation paramount. Taxpayers supporting a non-remunerated guarantee should maintain documentation that clearly sets out:
-
The expected benefits to the guarantor;
-
The consequences of not providing the guarantee;
-
The financial and operational interdependence between the entities; and
-
The direct impact of parent-level financial distress on the subsidiary.
The procedural takeaway is also important: if valid economic reasons are properly established before the trial court, they may be difficult to challenge on appeal.
Finally, it should be noted that the tax years under review in this case (i.e., fiscal years 2009 and 2010) predate the 2017 amendment to Article 110(7), which replaced the “normal value” wording with an explicit reference to arm’s length conditions and prices. While the Supreme Court’s emphasis on economic rationale remains relevant under today’s transfer pricing framework, the view that commercial reasons can fully shield a transaction from transfer pricing scrutiny should be treated with caution.
