VAT Amnesty and Assessment Deadlines: The Supreme Court Clarifies the Relationship with EU Law (Order No. 15260/2025)

Italian tax law is a complex field, made even more intricate by its interaction with European regulations. This dynamic is particularly evident when discussing tax amnesties, and specifically Value Added Tax (VAT), a subject extensively harmonized at the EU level. In this context, the intervention of the Supreme Court of Cassation, with Order No. 15260 of 08/06/2025, proves fundamental in clarifying a crucial aspect: the impact of disapplying domestic rules on VAT amnesties on the extension of assessment deadlines.

The Regulatory Framework: Tax Amnesties and European Law

Tax amnesties are extraordinary measures that allow taxpayers to regularize their tax position, often under favorable conditions. In Italy, they have been introduced through various laws over the years, including Law No. 289 of 2002, which contained specific provisions in Article 10. However, when these rules concern VAT, the principles of European Union law come into play, requiring Member States to ensure the full and effective collection of this tax, as it constitutes an own resource of the Union.

European case law has repeatedly emphasized that national regulations which, in effect, prevent or make the collection of VAT excessively difficult may be considered incompatible with EU law. In such cases, national judges are required to disapply the domestic rule that conflicts with EU law, based on the principle of the supremacy of Union law.

The Crucial Issue: Extension of Deadlines and Disapplication

Order No. 15260/2025 of the Court of Cassation was tasked with resolving a question of significant practical relevance: does the disapplication of VAT amnesty rules, due to their conflict with EU law, automatically lead to the nullification of the extended assessment deadlines that were provided precisely in conjunction with such amnesties? In other words, if the amnesty cannot be applied to VAT due to a European directive, does the tax administration also lose the additional time granted to conduct audits?

The Supreme Court's answer, in the case pitting the State Attorney's Office (A.) against the taxpayer D., was clear and aligned with a previously expressed orientation (see, in this regard, Ruling No. 17621 of 2018). Here is the relevant ruling:

The disapplication, due to conflict with Union law, of domestic provisions on VAT amnesties does not affect the extension of assessment deadlines under Article 10 of Law No. 289 of 2002, provided precisely to allow the administration to carry out the obligations imposed by the amnesty, without prejudice to the exercise of assessment powers, when, due to the taxpayer's choice or regulatory limitations, the preferential settlement cannot be achieved.

This statement is of fundamental importance. The Court clarifies that the extension of assessment deadlines, such as that provided for by Article 10 of Law No. 289 of 2002, has its own autonomous and instrumental function. It is not directly linked to the actual realization of the 'preferential settlement' (i.e., the benefit of the amnesty for the taxpayer) but is aimed at enabling the tax administration to perform the necessary tasks imposed by the amnesty regulations themselves. These tasks may include, for example, verifying submitted applications, examining documentation, and managing related procedures, regardless of whether the amnesty is ultimately granted to the taxpayer.

The Supreme Court, therefore, distinguishes between the substantive validity of the amnesty rule (which may be disapplied for VAT in case of conflict with EU law) and the validity of the procedural rules derived from it, such as the extension of assessment deadlines. This extension is considered an essential mechanism to:

• Ensure the Administration has sufficient time to evaluate the positions of taxpayers who have applied or could have applied for the amnesty.
• Prevent the disapplication of the amnesty itself from prejudicing the State's exercise of its assessment powers.
• Maintain the effectiveness of control actions, even when the facilitated settlement is not achieved for various reasons, such as the taxpayer's choice not to avail themselves of it or specific regulatory limitations.

Conclusions: Clarity and Certainty in Tax Law

Order No. 15260/2025 of the Court of Cassation offers an important point of reference in the complex interaction between national tax law and European Union law. By reiterating an already established principle, the Supreme Court ensures that the need to comply with European directives on VAT does not prejudice the tax administration's ability to conduct its audits within the deadlines linked to amnesties. This ruling helps to strengthen legal certainty, both for taxpayers, who can better understand the limits and consequences of applying for amnesties, and for the Administration, which sees the validity of its procedural tools confirmed. It is a clear example of how case law works to harmonize different sources of law, while ensuring the efficiency and legality of administrative action.
