Trust taxation and registration tax: an analysis of Ordinance no. 30343 of 2025

The trust represents one of the most complex and debated legal instruments within the Italian legal and tax landscape. Originating in common law systems, its integration into the national legal framework has required years of judicial interpretation to precisely define the applicable tax treatment. Recently, Ordinance no. 30343 of 17/11/2025 issued by the Court of Cassation has shed further light on a fundamental issue: when is the proportional inheritance and gift tax due, and when, conversely, should the simple fixed registration tax be applied?

The prerequisite of asset enrichment

The dispute brought to the attention of the Supreme Court concerns the appeal filed by B., represented by lawyer A. G. T., against the State Attorney General's Office. At the heart of the dispute is the very nature of the trust and the moment at which the proportional tax obligation arises. According to established case law, also referenced in this instance, the inheritance and gift tax cannot be separated from an actual enrichment of the beneficiary.

In many cases, the establishment of a trust and the transfer of assets into it do not result in an immediate transfer of wealth. The trustee, in fact, acts as a manager of the assets for a specific purpose or in favor of beneficiaries who might receive the proceeds or the capital only at a future and uncertain time. In such a scenario, the tax prerequisite provided for by Article 53 of the Constitution—namely, the contributory capacity manifested through an effective increase in assets—would be absent.

The distinction between fixed and proportional tax

The Supreme Court, with the ordinance under examination, reaffirms a principle of tax equity. To better understand the scope of this decision, it is useful to observe the following key points:

• Proportional tax is linked to the definitive transfer of rights.
• If the beneficiary does not immediately acquire full availability of the assets, the act is neutral from the perspective of enrichment.
• The mere segregation of assets in a trust does not, in itself, constitute a transfer of wealth taxable on a proportional basis.

This interpretation aligns with European and international regulations, in particular with the Hague Convention of July 1, 1985, implemented in Italy by Law no. 364 of 1989, which recognizes the legitimacy of the asset segregation typical of a trust.

Regarding trust taxation, the proportional inheritance and gift tax—which presupposes asset enrichment by way of liberality—applies where the definitive transfer of rights from the trustee to the beneficiary occurs at the time of the trust's establishment; otherwise, the act must be subject only to the fixed registration tax.

The commentary on this principle is essential for any professional or private individual intending to approach this instrument. The Court clarifies that the taxable moment does not necessarily coincide with the signing of the trust deed. If the deed provides that the assets will pass to the beneficiary only at the end of the trust or upon the occurrence of certain conditions, the proportional tax will be due only at that later stage. Initially, the endowment act will be subject exclusively to the fixed registration tax, as it is an act instrumental to management and not a completed act of liberality.

Conclusions on the scope of Ordinance 30343/2025

Ordinance no. 30343/2025 represents an important milestone for legal certainty in tax matters. It confirms that the tax authorities cannot levy taxes on potential wealth or a simple asset segregation operation if there is no real and current transfer of ownership that enriches the final beneficiary. For those wishing to use the trust as a tool for asset protection or succession planning, this ruling offers a clear guide to avoid tax overlaps and to correctly plan the costs associated with the management of one's assets.
