Citation: Civile Ord. Sez. 5 Num. 13136 Anno 2026
Applicant: Agenzia delle Entrate
Respondent: NN Europe S.p.A. (ora TN Italy S.p.A.)
Jurisdiction: Italy
Judgment date: 07/05/2026 (decided 8 January 2026)
Judgment Summary
Following a tax audit by the Guardia di Finanza, the Agenzia delle Entrate issued two assessment notices against NN Europe S.p.A. for the tax years 2009 and 2010, asserting that the company had provided real guarantees in favour of its US parent, NN Inc., without receiving any remuneration, and that the arm's length value of those guarantees should be taxed under the transfer pricing rules in Article 110, paragraph 7, of Presidential Decree (d.P.R.) 22 December 1986, n. 917.
The Provincial Tax Commission of Turin upheld the assessments at first instance. The Regional Tax Commission (Commissione Tributaria Regionale, CTR) of Piedmont, Section 4, reversed that decision on appeal, annulling both notices. The Agenzia delle Entrate then appealed to the Supreme Court on three grounds.
The Supreme Court dismissed the appeal, upheld the CTR's decision, and stated a binding principle of law to the effect that transfer pricing rules are excluded where valid economic reasons justify an intra-group guarantee transaction, as determined by the courts of fact.
Background
NN Europe S.p.A., an Italian company, was a member of the NN Group. The group entered into a financing arrangement with a pool of American banks. The ultimate beneficiary of that financing was NN Inc., a company incorporated under US law and the group parent.
In its 2009 balance sheet NN Europe S.p.A. recorded, under memorandum accounts (conti d'ordine) at the item "garanzie prestate", guarantees totalling € 41,996,000.00 ($ 60,000,000.00). Those guarantees comprised mortgages in favour of Keybank for € 10,000,000.00 and pledges in favour of the same bank for € 31,996,000.00.
NN Europe S.p.A. received no remuneration for providing those guarantees. The tax authorities considered that the transaction lacked valid economic reasons and proceeded to calculate an arm's length price under the CUP method. Applying a mean remuneration rate of 3.13% to the guaranteed amount of € 42,005,428.00, they determined additional taxable income of € 1,314,474.00 for each of the tax years 2009 and 2010.
For 2009, assessment notice n. T7E030107197/2011, notified on 23 December 2011, re-determined the declared tax loss from € 1,954,277.00 to € 639,803.00. For 2010, assessment notice n. T7E030104392/2012, notified on 20 November 2012, assessed additional IRES of € 361,481.00, plus interest and penalties.
Core Dispute
The central question was whether Article 110, paragraph 7, of d.P.R. n. 917/1986 applied to a real guarantee provided without remuneration by an Italian subsidiary to its foreign parent company within the same group.
The tax authority argued that transfer pricing rules applied to all intra-group transactions regardless of whether a price was charged, that the CTR had wrongly assessed the arm's length value by reference to indirect economic benefits rather than to a price or consideration in the technical sense, and that the CTR had incorrectly calculated the guaranteed amount when it characterised the imputed rate as usurious.
NN Europe S.p.A. contended that the transaction was economically justified by the need to preserve the group's continuity and, consequently, the survival of the Italian subsidiary itself, and that such valid commercial reasons excluded the application of transfer pricing rules.
Court Findings
The Supreme Court examined all three grounds of appeal together, finding them closely connected, and dismissed them as unfounded.
The court held that, within intra-group transactions, the concepts of gratuitousness and economic character must be assessed in their proper economic meaning. Account must be taken of the economic interest pursued, even indirectly, through a complex economic operation, including the overall regulation of interests and not merely the single act of disposition. The court referred to the theory of "compensatory advantages" (vantaggi compensativi) recognised in Cass., sez. un., 18 March 2010, n. 6538.
The court further held, drawing on Court of Justice of the EU judgment of 31 May 2018, Case C-382/16 Hornbach-Baumarkt, that the existence of valid economic reasons justifying an intra-group transaction is in itself sufficient to exclude the application of transfer pricing rules where the transaction is motivated by the parent's interest in the economic success of the group's entities.
The court also cited Court of Justice of the EU judgment of 8 October 2020, Case C-558/19 Pizzarotti, confirming that transfer pricing rules may restrict fundamental freedoms under the TFEU but can be justified to protect the balanced allocation of taxing powers, provided the rules are proportionate and the taxpayer is permitted to justify the commercial reasons underlying the intra-group transaction.
Applying those principles, the court found that the CTR had correctly concluded, as an unreviewable finding of fact, that NN Europe S.p.A. had discharged the burden of demonstrating the internal commercial reasons for the transaction. Those reasons were: the acquisition by the Italian subsidiary of an economic advantage in the form of future revenues and a positive differential on active and passive interest rates; and the particular financial circumstances of the group, including the parent's illiquidity, a reduction in subsidiaries' turnover, and the risk that insolvency proceedings against NN Inc. would inevitably have threatened the survival of the Italian subsidiary.
The court stated the following principle of law: where a subsidiary provides a guarantee in favour of its parent company, the transfer pricing rules do not apply when valid economic reasons justify the transaction, that justification being a question of fact for the courts of merit that is not reviewable on a point of law, and when the transaction is motivated by the parent's interest in the economic success of the various entities within the group.
Outcome
The Supreme Court dismissed the appeal (rigetta il ricorso). The two assessment notices issued by the Agenzia delle Entrate for IRES years 2009 and 2010 were annulled, as decided by the CTR. The Agenzia delle Entrate was ordered to pay NN Europe S.p.A.'s costs of the Supreme Court proceedings, liquidated at € 14,000.00 for fees, plus 15% for reimbursement of general expenses, CAP and VAT. The court noted that the double-contribution surcharge under Article 13, paragraph 1-quater, of d.P.R. 30 May 2002, n. 115 did not apply because the losing party was a public administration defended by the Avvocatura Generale dello Stato.
TP Method Highlighted
The Agenzia delle Entrate applied the Comparable Uncontrolled Price (CUP) method to determine the arm's length remuneration for the guarantee. It applied a mean remuneration rate of 3.13% to the guaranteed amount of € 42,005,428.00, producing additional taxable income of € 1,314,474.00 per year for 2009 and 2010. The CTR had noted that the total cost of the guarantees provided by all group companies, at that rate, would have implied an annual rate of 22%, which it characterised as usurious. The tax authority argued before the Supreme Court that the 22% figure represented the aggregate value for all group guarantees combined and that only the 3.13% rate was relevant for NN Europe S.p.A. specifically. The Supreme Court did not resolve this factual dispute directly, as it dismissed the appeal on the prior ground that transfer pricing rules did not apply at all in the circumstances.
Major Issues / Areas of Contention
- Whether Article 110, paragraph 7, of d.P.R. n. 917/1986 applies to an intra-group guarantee provided without remuneration.
- Whether the absence of a price or consideration in the technical sense prevents the application of transfer pricing rules to a gratuitous intra-group transaction.
- Whether indirect economic benefits, such as future revenues or preservation of business continuity, can constitute valid commercial reasons that exclude the application of transfer pricing rules.
- Whether the CTR's factual finding that the taxpayer had demonstrated valid economic reasons for the transaction was open to review by the Supreme Court.
- Whether the CUP rate of 3.13% applied by the tax authority was correctly calculated with reference only to NN Europe S.p.A.'s share of the guarantees, as opposed to the total group guarantee cost.
- The allocation of the burden of proof between the tax authority and the taxpayer in an intra-group transfer pricing adjustment involving a guarantee transaction.
