Statute of Limitations for Tax Debt and Installment Plans: The Clarification by the Court of Cassation with Order No. 16797/2025

The management of tax debt is a complex aspect of Italian tax law, often generating uncertainty for both taxpayers and industry professionals. Among the most debated issues is the interaction between an installment payment request for a debt and the running of the statute of limitations. A recent and significant intervention by the Court of Cassation, with Order No. 16797 of June 23, 2025, has provided a fundamental clarification, precisely outlining the consequences of installment payments on prescription terms. This ruling is part of a constantly evolving regulatory and jurisprudential framework, offering essential guidelines for the protection of taxpayer rights and the correct application of rules by collection agents.

The Principle of the Court of Cassation: Installment Payments and Statute of Limitations

The Supreme Court, with its Order No. 16797/2025, addressed a case involving B. and A., annulling with referral a previous decision by the Regional Tax Commission of Florence. The core of the issue concerned the correct interpretation of when the statute of limitations for tax debt resumes running once the taxpayer has requested and begun making installment payments. The statute of limitations, as is known, is a legal institution that extinguishes a right (in this case, the State's right to claim) due to the inertia of the holder for a certain period. However, this period can be interrupted by specific acts, such as the notification of a tax assessment notice or, as in this case, the request for an installment plan.

The principle extracted from Order No. 16797/2025 unequivocally clarifies:

In matters of tax debt installment plans, as long as the request made by the taxpayer in this regard has been followed up (with payments made by the due dates), the running of the statute of limitations – already interrupted by the aforementioned request – is postponed forward by each partial fulfillment: consequently, the collection agent cannot proceed with acts that interrupt the statute of limitations, which will resume its course at the moment when, according to the specific discipline of the institution, the taxpayer's default could have been asserted.

This principle is of extraordinary importance. It means that the request for an installment plan, in itself, interrupts the statute of limitations pursuant to Article 2943 of the Civil Code, as it constitutes an acknowledgment of the debt by the taxpayer (Art. 2944 c.c.). But not only that: the Court of Cassation specifies that, as long as the taxpayer adheres to the installment plan with punctual payments, each individual partial payment acts as a new interrupting event, postponing the moment when the statute of limitations resumes running. In other words, the statute of limitations does not restart from zero after the initial request but is continuously "updated" by each installment paid.

Practical Consequences for the Taxpayer and the Collection Agent

The implications of this ruling, contained in Order No. 16797/2025, are numerous and of great practical relevance. For the taxpayer who has obtained an installment plan and is honoring it, the Court of Cassation's decision offers greater peace of mind: as long as payments are regular, the collection agent cannot and must not undertake further actions aimed at interrupting the statute of limitations, such as sending reminders or notices. This avoids unnecessary duplication of acts and potential disputes. The statute of limitations, in fact, will only resume its normal course from the moment an actual default by the taxpayer occurs with respect to the established installment plan, according to the specific discipline of the institution (e.g., DPR 602/1973).

For the collection agent, this order clarifies the limits of their action, requiring greater attention to the management of installment plans and the monitoring of payments. The agent cannot act arbitrarily but must await the moment of default to reassert their credit right and, consequently, the resumption of the statute of limitations. This principle reinforces the duty of good faith and fairness also in the context of tax collection.

• **Clarification on the commencement of the statute of limitations**: The statute of limitations does not restart from the date of the installment plan request but is postponed with each individual payment.
• **Protection for the diligent taxpayer**: Those who adhere to the installment plan are protected from further acts by the agent that would interrupt the statute of limitations.
• **Limits to the collection agent's action**: The agent can act to interrupt the statute of limitations only in case of actual default of the installment plan.

Conclusions and the Importance of Legal Advice

Order No. 16797/2025 of the Court of Cassation represents a firm point in the complex matter of the statute of limitations for tax debts in the case of installment plans. It offers legal certainty and protects the taxpayer who, despite facing difficulties, commits to honoring their debts through an agreed payment plan. At the same time, it provides clear guidance to collection agents on how to manage such situations.

Given the complexity of the subject matter and the continuous jurisprudential developments, it is always advisable for taxpayers facing tax debt situations and installment plans to seek the assistance of professionals experienced in tax law. Qualified legal advice can make a difference, ensuring the correct application of the principles enunciated by the Supreme Court and the full protection of one's rights.
