Payment demand and statute of limitations: the Court of Cassation clarifies with order no. 28862/2025

In the complex landscape of Italian tax litigation, the relationship between the taxpayer and the tax authorities is governed by strict deadlines and precise procedural principles. One of the most debated issues concerns the possibility of challenging a payment demand (intimazione di pagamento) by raising objections that should have been asserted against previous acts that have since become final. The Court of Cassation addressed this delicate matter with order no. 28862 of October 31, 2025, providing a fundamental clarification for professionals and taxpayers alike.

The case and the nature of the payment demand

The dispute involved the State Attorney's Office and the taxpayer S. The Regional Tax Commission of Catanzaro had previously ruled in favor of the taxpayer, but the Supreme Court overturned this decision, upholding the Administration's appeal. The core of the decision lies in the legal definition of the payment demand: it does not represent a new and autonomous tax assessment act, but rather a merely executive and consequential act.

The payment demand following a tax assessment act that has become final does not constitute a new and autonomous tax assessment act; consequently, it may be challenged in court only for its own inherent defects and not for issues pertaining to the act from which the debt arose. Therefore, the taxpayer is precluded from raising the statute of limitations of the claim when challenging the subsequent payment demand, even if such limitation had already accrued prior to the notification of the unchallenged preliminary acts.

Limits on challenges and the plea of statute of limitations

As highlighted in the principle stated above, the taxpayer cannot use the challenge of a payment demand as a means to remedy the failure to contest previous acts (the so-called preliminary acts). If a notice of assessment or a payment folder (cartella di pagamento) is not challenged within the statutory time limits, it becomes final. Consequently, any defect relating to such acts, including the statute of limitations of the claim accrued before their notification, can no longer be raised at a later stage.

The challengeability of the payment demand is therefore limited exclusively to its own inherent defects. What are these defects? Here are some practical examples:

• Material or calculation errors intrinsic to the demand itself.
• Omitted or defective notification of the demand act.
• Statute of limitations of the claim accrued exclusively at a time subsequent to the notification of the preliminary act that has become final.

Conclusions and implications for taxpayer defense

The ruling of the Court of Cassation with order no. 28862/2025 reaffirms the principle of legal certainty and the stability of tax relations. For taxpayers, this decision serves as a stern warning: timeliness in defense is everything. Ignoring a tax assessment act in the hope of being able to contest the debt during the compulsory collection phase is a failed strategy. Upon receipt of any tax-related act, it is essential to immediately consult a professional to evaluate the opportunity for a timely appeal.
