When a judge issues a judgment ordering the payment or restitution of sums of money, a crucial doubt often arises for the parties involved: which tax regime applies for the purposes of registration tax? The issue is not merely academic, as the difference between the proportional rate and the fixed amount can lead to a significantly different economic burden. The Court of Cassation intervened on this point with Ordinance no. 30706 of November 21, 2025, offering a fundamental clarification on the taxation of restitutionary effects deriving from the invalidity of an act.
The Consolidated Law on Registration Tax (D.P.R. 131/1986) regulates in detail how the measures of the judicial authority must be taxed. In general, judgments ordering the payment of sums or values are subject to proportional tax, as they represent a new transfer of wealth or the recognition of a credit. However, the legislature has provided for a favorable regime for those situations in which the order is merely the consequence of the termination of an original legal relationship. In summary, the criteria followed by jurisprudence are as follows:
The matter arises from a dispute between the State Attorney General's Office (A.) and the taxpayer T. D. I. The Regional Tax Commission of Milan had previously annulled a liquidation notice with which the Revenue Agency claimed proportional tax on a judgment ordering the restitution of sums. These sums had been paid in execution of a financial lease assignment agreement which the civil judge had, however, declared ineffective due to the lack of consent of one of the contracting parties. The Court of Cassation, rejecting the Office's appeal, confirmed that in such circumstances there is no transfer of wealth taxable at a proportional rate.
Regarding registration tax, measures of the judicial authority ordering the payment or restitution of sums of money are subject to proportional taxation pursuant to art. 8, paragraph 1, letter b), of the first part of the tariff attached to the TUR, unless such an order is accompanied by the annulment or declaration of nullity of an act, in which case the fixed-rate tax applies, pursuant to art. 8, paragraph 1, letter e), of the aforementioned tariff, given the absence of a transfer of wealth that characterizes the restitutionary effect of the undue payment deriving from the invalidity of the act.
This principle is of extreme importance: the restitutionary effect of an undue payment, when it arises from the invalidity or ineffectiveness of an act, does not constitute a new manifestation of contributory capacity. Money that returns to the hands of the rightful owner following a null or ineffective contract does not represent an increase in assets, but only the repair of an original legal error.
Ordinance no. 30706/2025 is in line with previous legitimacy guidelines (see judgment no. 32969 of 2018), reiterating that registration tax must target the economic substance of the act. If there is no new wealth, but only a rebalancing due to the invalidation of a legal transaction, the taxpayer is entitled to the application of the fixed rate. This ruling represents a further guarantee for citizens and businesses, preventing civil justice from indirectly becoming an occasion for disproportionate tax collection by the Treasury.
