Notification of Payment Notice: The Court of Cassation Clarifies the Liability of a Business Branch Acquirer with Order No. 15862/2025

The complexity of tax law and the dynamics of corporate transactions, such as the acquisition of business branches, often generate crucial questions regarding the correct allocation of tax liabilities. One of the most debated issues concerns the notification of payment notices: is a new notification to the acquirer of a business branch always necessary, even if the notice has already been served on the transferor? The Court of Cassation authoritatively addresses this point, providing a clarifying interpretation with Order No. 15862 of June 13, 2025. This ruling offers important insights for understanding collection mechanisms and taxpayer protections.

The Regulatory Framework and the Key Issue

The core of the issue lies in the application of Article 25 of Presidential Decree No. 602 of 1973, a fundamental provision on tax collection. This article governs the methods of notifying a payment notice, stipulating that it must be delivered to the taxpayer registered in the tax roll or to the joint obligor against whom proceedings are being taken. Practice and case law have often had to deal with situations where tax liability is transferred or extends to parties other than the original debtor, as is the case with the acquisition of a business branch.

When a business branch is acquired, liabilities, including tax liabilities, may also fall upon the acquirer, albeit subsidiarily to the transferor. The question arises whether mere notification to the transferor is sufficient to make the tax claim effective against the acquirer as well, or if the latter is entitled to receive an independent notification to contest the debt. The solution to this uncertainty is crucial for ensuring legal certainty and guiding the actions of both the Tax Administration and businesses and their advisors.

The Interpretation of the Court of Cassation: The Maxim and Its Meaning

With Order No. 15862 of 2025, the Court of Cassation, Section T, presided over by G. L. R. and with L. L. as rapporteur, offered a decisive interpretation, quashing and remanding a previous decision of the Regional Tax Commission of Rome of December 30, 2022. The dispute pitted A. (Advocacy General of the State) against H. (represented by G. S.). The Court clarified that:

In cases where the payment notice has been served on the transferor of the business branch, for the purpose of continuing collection against the acquirer, a further notification to the acquirer is not necessary, since Article 25 of Presidential Decree No. 602 of 1973 provides for alternative notification to the taxpayer registered in the tax roll or to the joint obligor against whom proceedings are being taken. The obligation of the transferor – the taxpayer – constitutes an element of the obligation of the acquirer who is liable subsidiarily, with the consequence that it is with respect to the transferor that it must be ascertained that the tax is due.

This maxim is of paramount importance. The Court of Cassation emphasizes that Article 25 of Presidential Decree No. 602 of 1973 offers an alternative option for notification: to the primary debtor or to the joint obligor. In the context of a business branch acquisition, the acquirer's liability is subsidiary to that of the transferor. This means that the original tax obligation arises with the transferor, who is the taxpayer. The acquirer's obligation, although existing, is derived, a
