Abuse of Law and Leveraged Buyout Mergers: Cassation Ruling 16559/2025
Corporate restructuring operations, particularly complex ones like leveraged buy out (LBO) mergers, are fundamental tools for business growth and reorganization. However, their intricate nature often raises questions about tax legitimacy, as they can be perceived as vehicles for tax evasion. In this context, the recent Ruling No. 16559, filed on June 20, 2025, by the Court of Cassation, serves as a beacon of clarity, delineating the boundaries between legitimate tax planning and the abuse of law. This decision, with Dr. M. C. as rapporteur and Dr. R. C. as president, offers crucial insights for legal professionals and entrepreneurs.
Abuse of Law in Italy: Regulatory Framework and Relevance for Businesses
The concept of abuse of law in tax matters has long been a subject of debate and uncertainty. Initially governed by Article 37-bis of Presidential Decree No. 600 of 1973 (now incorporated into Article 10-bis of Law No. 212 of 2000, the Taxpayer's Statute), it aims to counteract operations lacking economic substance that, while formally complying with the law, have the sole or primary purpose of obtaining undue tax advantages. Both national and European case law have consistently reiterated the need to identify a causal link between the operation and the tax advantage, excluding abuse when the operation is justified by valid, non-marginal economic reasons.
The leveraged buy out merger, as defined by Article 2501-bis of the Civil Code, is a complex financial transaction where a company (the "target") is acquired by a specially established company (the "newco"), which incurs significant debt to finance the purchase. Subsequently, the "newco" merges with the "target," and the incurred debts are repaid using the cash flows of the resulting merged company. The nature of this operation, often characterized by substantial tax advantages derived from the deductibility of interest expenses on the financing, has made LBO mergers a fertile ground for challenges by the tax authorities.
The Specific Case: Cassation Ruling No. 16559/2025
The ruling under review, stemming from the appeal by W. (represented by lawyer A. T.) against A., and in which Public Prosecutor T. B. expressed a conforming opinion, directly addresses the admissibility of an LBO merger operation within the context of abuse of law. The Court of Cassation, quashing and remanding a previous decision by the Regional Tax Commission of Palermo, provided precise guidance on the criteria for assessing the tax legitimacy of such operations. The summary principle expressed by the Court is as follows:
In matters of abuse of law, pursuant to Article 37-bis of Presidential Decree No. 600 of 1973, applicable ratione temporis, a leveraged buy out merger operation, as defined by Article 2501-bis of the Civil Code, may not have the primary and overwhelming purpose of evading taxes, finding justification in a broader corporate restructuring project aimed at the entry of new shareholders, even when, following the operation, the previous shareholders remain in the shareholding structure of the target company, provided that their exclusive control ceases and the pre-existing control structure is significantly altered (so-called change of control).
This passage is of fundamental importance. The Cassation clarifies that an LBO merger is not automatically abusive simply because the pre-existing shareholders remain in the "target" company's shareholding structure after the merger. What matters, to exclude a predominant evasive intent, is that the operation is part of a
