The Italian Supreme Court has issued a landmark ruling in Case No. 5753/2026, involving KAI S.R.L. (Shell Italia Aviazione), which sets a strict precedent regarding the deductibility of costs for intra-group services. This ruling emphasizes that, in the current tax audit environment, the existence of a contract and an invoice is no longer sufficient to substantiate the economic reality of a transaction.
The court reaffirmed the importance of the “Benefit Test”, determining that the burden of proof rests entirely with the taxpayer, who must demonstrate in an objective and documented manner that the services received contributed real value to its local operations.
The Dispute: Lack of Evidence Regarding the Benefit Received
The dispute arose when the Italian Tax Agency rejected the deduction of 1,389,576 euros in costs for services provided by the group’s parent company. According to the authority, the documentation provided by KAI S.R.L. failed to establish a direct connection between the invoiced costs and the specific needs of the business in Italy.
The critical points identified in the ruling include:
- Shareholder services vs. support services: A large portion of the costs were classified as control or coordination activities by the parent company (shareholder activities), which are not deductible for the subsidiary as they do not represent a commercial benefit of its own.
- Insufficient generalities: The company’s defense, based on the argument that its high turnover with few employees justified the need for external services, was deemed insufficient by the Court, which characterized it as a “general assertion.”
- Insufficient documentation: It was determined that the mere presentation of contracts and invoices does not constitute proof of benefit; technical and specific evidence of the service’s provision is required.
Discrepancy in classification: Article 110(7) vs. 109(5) TUIR
A relevant technical aspect of the case was the tax authority’s error in citing the regulations in the initial notification. Despite this, the Supreme Court upheld the objection, establishing that as long as the facts of the case are clearly set forth, the error in the legal reference does not invalidate the audit.
This puts companies on alert: economic substance and the analytical description of the facts take precedence over procedural formalities, requiring that the technical defense of Transfer Pricing be flawless from the outset.
Impact on Transfer Pricing Management
This ruling is not an isolated event within the Italian jurisdiction; it reflects a global trend aligned with the OECD guidelines (Chapter VII of the 2022 Guidelines). When analyzing intra-group charges, authorities now require full traceability demonstrating:
- Necessity: Would an independent third party have paid for this service under similar conditions?
- No Duplication: Is the service already performed by the subsidiary’s internal staff?
- Economic Value: How did this service improve the local entity’s commercial or financial position?
Any inconsistency in this narrative can lead to significant tax adjustments and the reclassification of expenses as non-deductible, directly affecting the group’s tax base.
Relevance for Global Compliance and Tax Planning
The current landscape requires multinational groups to stop treating intra-group services as automatic accounting entries and to integrate them into their proactive compliance strategy. The visibility of this data under transparency regulations means that authorities will compare what is reported in Country by Country Reports (CbCR) with the operational reality of local offices.
To mitigate risks, it is essential that organizations:
- Document the service “deliverable”: Retain reports, emails, minutes, and any evidence of service execution.
- Segment services: Clearly separate operational support expenses from parent company administrative expenses.
- Update their Transfer Pricing Local Files: Ensure that the charging policy is aligned with the company’s operational reality in the current fiscal year.
Conclusion: Implications for Multinational Groups
The case KAI S.R.L. v. Italy confirms that transparency and technical evidence are now the cornerstones of tax defense. It is no longer sufficient to merely comply with the formal submission of guidelines or returns; companies must ensure that every euro, dollar, or sol paid to a related party is defensible under the arm’s length principle and the arm’s length profit principle.
In this context of increased scrutiny of intra-group services, having specialized advice is vital. At TPC Group, we support organizations in strengthening their Transfer Pricing documentation, ensuring that their operations meet the highest international standards to prevent contingencies and strengthen their tax reputation.
