Tax Injunction and Prior Notice: The Court of Cassation Clarifies with Ruling No. 17640/2025

The landscape of tax law and enforcement proceedings is constantly enlivened by judicial pronouncements that define the boundaries and methods of action for tax authorities and taxpayers. In this context, the Court of Cassation, with ruling no. 17640 of June 30, 2025, has addressed a matter of considerable practical importance: whether the tax injunction, issued pursuant to Royal Decree no. 639 of 1910, must be preceded by the notice provided for in Article 1, paragraph 544, of Law no. 228 of 2012. A ruling that, as we shall see, directly impacts taxpayers' rights and collection procedures.

Regulatory Context and the Controversial Issue

To fully understand the scope of the Cassation Court's decision, it is essential to outline the relevant regulatory framework. On one hand, we have Royal Decree no. 639 of 1910, which governs the collection of public entities' patrimonial revenues and, in particular, the tax injunction as an enforcement title for the compulsory collection of debts, including tax debts, by entities other than the Revenue Agency or, more generally, for the collection of revenues not entrusted to the national concessionaire. On the other hand, Law no. 228 of 2012 (Stability Law 2013), in Article 1, paragraph 544, introduced the obligation for local authorities and the Revenue Agency to send a prior notice to the taxpayer before proceeding with the registration in the tax roll of sums due following automated or formal checks of tax returns.

The controversial issue, which was the subject of the appeal examined by the Court of Cassation between parties S. and C., concerned precisely the compatibility and necessity of applying this prior notice also to tax injunctions under R.D. no. 639 of 1910. Was it legitimate for an entity to proceed with collection via injunction without first notifying the taxpayer with the 2012 notice?

The injunction issued pursuant to art. 2 of R.D. no. 639 of 1910 does not need to be preceded by the notice referred to in art. 1, paragraph 544, of L. no. 228 of 2012.

This is the headnote extracted from ruling no. 17640 of 2025, which summarily encapsulates the Supreme Court's decision. The ruling, with Dr. R. R. as rapporteur and Dr. D. S. F. as president, quashed and decided on the merits a previous ruling by the Court of Verona of November 29, 2022, unequivocally stating that there is no obligation to send the 2012 prior notice before a 1910 tax injunction. But what are the reasons for this decision?

The Cassation Court's Analysis: Why the Notice is Not Due

The Court of Cassation, in justifying its decision, highlighted the structural and functional differences between the two acts and their respective regulations. The notice referred to in Article 1, paragraph 544, of L. no. 228 of 2012 is specifically designed for acts of assessment and automated or formal checks of tax returns, i.e., for those phases in which the tax administration, before making a debt final, offers the taxpayer the opportunity to regularize their position or provide clarifications. It is, in essence, a compliance measure aimed at ensuring prior adversarial proceedings and promoting voluntary compliance, thereby reducing litigation.

The tax injunction, conversely, while being an enforcement title, falls within a different context. It is a tool for compulsory collection that presupposes the existence of a certain, liquid, and enforceable debt, often already defined by other acts (e.g., unchallenged assessment reports or judgments). Its nature is, therefore, closer to the enforcement of an already ascertained debt rather than a preliminary phase to the assessment itself. The Cassation Court implicitly reiterated that the scope of application of the 2012 notice is limited to debts arising from automated or formal checks, and does not indiscriminately extend to every form of compulsory collection, including tax injunctions issued by entities other than the Revenue Agency under R.D. no. 639/1910.

In this sense, the ruling aligns with established jurisprudence that tends to distinguish collection procedures and instruments, avoiding analogical extensions not supported by the letter of the law. The Court thus confirmed the specificity of the tax injunction as a direct collection instrument for entities, without burdening it with procedural requirements designed for other types of tax acts. This interpretation also avoids excessive bureaucratization of debt recovery procedures by local authorities, while upholding the principles of legality and taxpayer protection, which are guaranteed in other phases and defense tools, such as opposition to the injunction itself.

Practical Implications for Taxpayers and Entities

Ruling no. 17640 of 2025 has significant practical implications for both parties involved in the collection process:

• For Taxpayers: It means that, in case of receiving a tax injunction issued under R.D. no. 639/1910, they cannot claim its nullity due to the lack of prior notice under art. 1, paragraph 544, L. no. 228/2012. Defense must therefore focus on other defects of the act or the underlying debt, such as prescription, illegitimacy of the original debt, or calculation errors. It is therefore crucial to always be vigilant and ready to promptly contest the injunction, availing oneself of necessary legal assistance.
• For Taxing and Collection Entities: The ruling offers clarity and confirms the legitimacy of collection procedures via tax injunction without the burden of a specific prior notice from 2012. This can streamline processes and make debt recovery more efficient, but at the same time requires entities to ensure the full legitimacy and validity of the underlying debt, as taxpayer protection shifts more towards the phase of challenging the injunction itself.

Conclusions

The ruling of the Court of Cassation no. 17640 of 2025 represents a firm point in the interpretation of the rules governing compulsory collection. By clearly distinguishing the scope of application of the 2012 prior notice from the 1910 tax injunction, the Supreme Court has provided clear guidance for legal professionals and citizens. While on one hand, the speed and effectiveness of the tax injunction as a debt recovery tool are confirmed, on the other hand, the importance for the taxpayer to know their rights and to act promptly and consciously, relying on expert professionals, is reinforced when faced with payment requests from entities. Citizen protection, in fact, while not passing through prior notice in this specific case, remains solid through the possibility of opposition and verification of the substantial and formal legitimacy of the claimed debt.
