A recent ruling of the Italian Supreme Court (No. 5,753, dated March 13 2026) provides a significant and instructive contribution to the debate on the tax treatment of intra-group services and their interaction with transfer pricing rules. The decision addresses a recurring issue in multinational group structures: under what conditions costs charged between associated enterprises can be considered deductible for corporate income tax purposes.
The facts of the case
The case arose from a tax audit conducted in 2012 on an Italian company operating in the aviation fuel sector, which was part of a multinational group. The company was wholly owned by an Italian holding entity and participated in a domestic tax consolidation regime.
Following the audit, the Italian Revenue Agency issued several tax assessments, challenging, among other items, the deductibility of costs arising from intra-group service agreements. These agreements – commonly referred to as cost contribution agreements – had been entered into with a UK-based affiliate.
The agreements covered two main categories of services:
Business support services – including centralised functions such as human resources, finance, IT, legal services, procurement, and credit management; and
R&D and technical support services – relating to innovation, product development, intellectual property management, and technical assistance.
Costs were allocated among group entities based on a revenue-based key linked to the global aviation business segment.
The position of the Italian tax authority
The Italian tax authority argued that a substantial portion of these costs was not deductible, primarily on the grounds of lacking “inherence”. According to the agency, the taxpayer had failed to demonstrate that the services provided generated a specific and direct economic benefit for the Italian entity.
The agency highlighted several key points:
The services appeared generic and centralised, rather than tailored to the needs of the Italian company;
The documentation provided did not clearly establish a functional link between the services and the taxpayer’s business activity;
Some activities seemed more aligned with shareholder functions or group coordination, which are typically non-deductible; and
The alleged benefits were neither measurable nor objectively verifiable.
The position of the lower courts
At first instance, the provincial tax court ruled entirely in favour of the taxpayer, annulling the assessments.
On appeal, the Regional Tax Court (CTR) of Lombardy largely upheld the decision, confirming the deductibility of the intra-group costs. The CTR reasoned that:
The services were functionally connected to the company’s business, even if only “in a broad sense”;
In a multinational group, centralised services may legitimately serve general organisational needs; and
The Italian company had benefited from being part of a structured and coordinated group, enabling it to generate significant revenues despite a limited internal workforce.
However, the CTR partially accepted the tax authority’s position regarding costs allocated to the wrong fiscal year, applying the principle of accrual (competence).
The Supreme Court’s analysis
The Supreme Court partially overturned the decision, reaffirming that inherence must be assessed before transfer pricing and that the taxpayer bears the burden of proving:
The actual provision of services,
A specific and concrete benefit; and
Adequate documentation of that benefit.
A key contribution of the ruling lies in the court’s effort to clearly disentangle two concepts that are frequently conflated in practice: inherence and transfer pricing. The former concerns the very nature of the cost – whether it is genuinely connected to the taxpayer’s business activity and capable of contributing, even potentially, to the production of income. The latter, by contrast, comes into play only at a later stage and relates to the valuation of that cost; namely, whether the price applied between associated enterprises reflects arm’s-length conditions.
By drawing this distinction, the court emphasises that these are not overlapping or interchangeable tests but logically sequential steps in the analysis. A cost cannot be deemed deductible simply because it is priced correctly under transfer pricing rules; it must first pass the more fundamental threshold of inherence. If that threshold is not met – if the cost is not sufficiently linked to the business activity – then any discussion of its arm’s-length nature becomes irrelevant.
In this sense, the ruling reinforces a structured analytical approach: the economic relevance and utility of the cost must be established first, and only thereafter can one turn to the question of whether the amount charged is consistent with market conditions.
The court criticised the CTR for relying on generic statements about the usefulness of services, without verifying their real connection to the company’s activity.
Key takeaways
This ruling represents a significant development in Italian tax jurisprudence on intra-group services and transfer pricing.
The key point of the judgment is that deductibility depends on concrete proof, not abstract justification.
The decision reinforces the central role of the benefit test and demands a detailed, evidence-based approach to intra-group transactions. It also clarifies the analytical framework by distinguishing, yet connecting, inherence and transfer pricing.
According to the Supreme Court, in order for intra-group service costs to be deductible, the taxpayer must:
Demonstrate actual performance of the services – it is not sufficient to produce contracts and invoices;
Demonstrate objective measurability and documentation of that benefit; and
Provide specific evidence of how each service contributed to its business – generic references to group-wide advantages are inadequate.
