Italy's Supreme Court has ruled that subsidiaries are not required to charge parent companies for providing financial guarantees when legitimate economic reasons exist, rejecting the Revenue Agency's attempt to impose transfer pricing rules on unpaid intragroup collateral.
Italy’s Supreme Court has clarified the circumstances in which domestic transfer pricing rules apply to intragroup transactions, confirming that transactions conducted without consideration may remain outside the scope of transfer pricing where supported by legitimate economic reasons.
The clarifications have been provided under Order No. 13136 of 7 May 2026.
The central conflict involves transfer pricing regulations and whether a subsidiary’s unpaid collateral guarantees for its parent company should be taxed as missed income. The court examined whether such intercompany transactions must always have a formal price or if they can be justified by indirect economic benefits and group stability.
Ultimately, the judges rejected the Revenue Agency’s appeal, ruling that valid commercial reasons and “compensatory advantages” can justify non-remunerated guarantees. This decision establishes that subsidiaries are not required to charge their parent companies for financial support if the operation protects the entire group’s survival.
The following details the legal dispute and eventual Supreme Court ruling regarding tax assessments issued against NN Europe S.p.A. (now TN Italy S.p.A.) concerning infragroup guarantees.
Facts
The legal dispute originated from a tax audit conducted by the Guardia di Finanza, which led the Italian Revenue Agency to issue tax assessments for the 2009 and 2010 tax years against NN Europe S.p.A.
The Agency contested that the Italian company had recorded EUR 41,996,000 (approximately USD 60 million) in its 2009 financial statements as “guarantees provided,” which consisted of EUR 10 million in mortgages and EUR 31,996 million in pledges given to Keybank. These guarantees were part of a financing agreement with a pool of American banks for the benefit of the parent company, NN Inc., a US entity.
Tax authorities argued that the Italian subsidiary provided these significant real guarantees without seeking any form of remuneration, an operation they deemed lacked valid economic reasoning. Consequently, the Revenue Agency applied transfer pricing regulations under Article 110 of d.P.R. 917/1986, using the Comparable Uncontrolled Price (CUP) method to calculate a “normal value” for the service.
By applying a 3.13% average remuneration rate to the guaranteed amount, the Agency determined an additional taxable income of EUR 1,314,474 for each year, resulting in significant tax increases, interest, and penalties. While the Provincial Tax Commission of Turin initially rejected the company’s appeals, the Regional Tax Commission of Piedmont later overturned those decisions, leading the Revenue Agency to seek a final ruling from the Supreme Court.
Decision
The Supreme Court ultimately rejected the Revenue Agency’s appeal, upholding the principle that infragroup guarantees can be justified by broader economic interests rather than immediate fees.
The Court explained that in the context of multinational groups, “gratuitousness” must be evaluated based on the overall economic interest and the “compensatory advantages” theory, where a subsidiary may receive an indirect utility—such as ensuring business continuity—by supporting its parent company.
In this specific case, the company successfully demonstrated valid internal commercial reasons for the transaction: the parent company, NN Inc., was facing severe illiquidity and the risk of insolvency proceedings, which would have inevitably threatened the survival of the Italian subsidiary itself. The Court noted that European Union case law supports the idea that transfer pricing rules should not be applied when a taxpayer can justify the commercial logic behind an infragroup transaction.
Therefore, the Court established a clear legal principle: transfer pricing regulations do not apply to guarantees provided by a subsidiary to a parent company when there are valid economic reasons and a shared interest in the group’s success. As a result of the ruling, the Revenue Agency was ordered to pay the legal costs of the proceedings, liquidated at EUR 14,000 plus additional expenses.
