The recent Supreme Court ruling highlights the importance of applying individual corporate tax rules, particularly the principle of relevance, within a fiscal consolidation framework.
Despite the unified taxable income of a group, each entity must adhere to its own business income rules, which can lead to costs being deemed non-deductible if they lack relevance.
This decision overturns previous judgments favoring taxpayers and emphasizes the need for careful tax calculations within consolidated groups.

Overview of the Supreme Court Decision
The recent Supreme Court decision (n. 17433 of June 25, 2024) underscores the necessity of applying individual business income rules, particularly the principle of relevance, to each company within a fiscal consolidation. This ruling challenges the notion that a single group taxable income can shield entities from tax disputes.Implications of the Ruling
The decision emphasizes that the principle of relevance, which dictates that a company's revenue should offset another's cost within a consolidated group, must be applied to each entity individually. This can result in costs being considered non-deductible if they lack relevance to the entity receiving the service.Historical Context and Case Details
The case involved intra-group services such as commercial strategy and financial affairs, which were deemed insufficiently detailed and lacking valuation parameters in invoices. The initial rulings favored the taxpayer, citing the prohibition of double taxation under Article 163 of the TUIR, but the Supreme Court reversed this, highlighting the indivisibility of business income rules.Broader Legal and Fiscal Implications
The ruling clarifies that fiscal and civil law do not allow arbitrary allocation of income and expenses between companies within a consolidated group. This decision aligns with previous judgments, such as Cassation 17195/2006, reinforcing the non-negotiable nature of business income determination rules.Critical Aspects and Potential Issues
- The challenge of ensuring compliance with individual business income rules within a consolidated framework.
- The potential for increased scrutiny and disputes over cost relevance and deductibility.
Common Pitfalls and Errors
- Assuming that fiscal consolidation automatically resolves intercompany cost allocations.
- Overlooking the necessity of detailed documentation and valuation in intra-group transactions.
Suggestions and Useful Guidelines
- Maintain meticulous records and justifications for intra-group services and costs.
- Apply the same level of scrutiny to intra-group transactions as would be applied outside a consolidated framework.
