Following a line of authority aimed at curbing expansive interpretations of the concept of corporate groups with judgment No. 9260 of 13 April 2026, the Italian Supreme Court has made a significant contribution to the law governing corporate links under Article 2359(3) of the Italian Civil Code, clarifying the conditions required for such a link to be established where family relationships exist between shareholders of different companies, and the limits of the tax neutrality regime applicable to intra-group financial transfers.
Background and Legal Question
The case arose from a tax assessment issued by the Italian Revenue Agency against a limited liability company that had recorded in its balance sheet, as intra-group financing liabilities, sums received from two other companies whose shareholders were related by blood or marriage to the sole shareholder of the first company. The Regional Tax Court of Calabria (CTR), hearing an appeal against a first-instance judgment of the Provincial Tax Court (CTP) of Vibo Valentia, which had upheld the tax reassessment, finding no corporate link between the companies within the meaning of Article 2359 c.c., had reversed that decision. The CTR accepted the taxpayer's argument, finding the existence of a corporate link among the three companies, and therefore of a corporate group, on the sole basis of family relationships between their shareholders. In the CTR's view, those ties gave rise to a presumption of the "significant influence" that each company would exercise over the others, by virtue of an assumed community of interests and objectives. On that basis, the CTR recognised the tax neutrality of the financial flows in question. The Revenue Agency appealed to the Supreme Court.
Principles Established by the Court
Allowing the Revenue Agency's appeal, the Supreme Court set out three distinct and significant principles of law.
First, the Court held that an external corporate link cannot be inferred solely from family relationships between shareholders of different companies. Establishing such a link requires a concrete assessment of whether one entity actually exercises significant influence over the strategic decision-making of the other at shareholder level. A mere relationship of consanguinity or affinity between shareholders of different companies may be a relevant factor, but is not in itself sufficient: it is necessary to identify the dominant entity, the specific mechanisms through which influence is exercised, and the concrete shared economic objectives that flow from it.
Second, the Court reaffirmed and sharpened the distinction between the concept of a corporate link and that of a corporate group. A corporate link is a "relationship existing solely between the company that is subject to influence and the company that exercises it," operating at shareholder level pursuant to Article 2359(3) c.c. A corporate group, by contrast, "corresponds to an aggregation of enterprises incorporated as separate legal entities, formally autonomous and independent, but subject to unified management," and requires rigorous proof of the exercise of management and coordination activity under Article 2497-sexies c.c., which the law presumes only where control exists under Article 2359(1) c.c., not where there is a mere link under paragraph 3. The Court thus clarified that the existence of a corporate link does not, of itself, presuppose the existence of a group.
Third, on the tax law dimension, the Court ruled that the tax neutrality of intra-group transfers provided for under Article 118 of the Consolidated Income Tax Act (TUIR) applies exclusively to companies that have elected group taxation under Article 117 TUIR and are in a control relationship within the meaning of Article 2359(1)(1) c.c. The Court also excluded the possibility of any prohibited double taxation under Article 163 TUIR where tax is imposed on different subjects on the basis of distinct legal grounds.
Practical Implications
The judgment carries significant practical implications both on the corporate and the tax side.
From a corporate law perspective, it requires practitioners to document rigorously the actual exercise of significant influence by one company over another whenever a link under Article 2359(3) c.c. is invoked, mere reference to family ownership structures, shared registered offices, or common attorneys-in-fact will no longer suffice.
From a tax perspective, the decision definitively forecloses interpretations that extend the intra-group neutrality regime beyond its statutory perimeter, with material consequences for tax assessments and litigation involving "de facto" groups that have not been formally structured. This is particularly relevant in cross-border contexts, where the boundaries of a group are often tested both by tax authorities and in the context of transfer pricing reviews and thin capitalisation analyses.
