In the language of contemporary wealth planning, few expressions are as evocative as the “sham shield US trust”. It is not a legal definition, nor a codified category. It is, rather, an effective — and deliberately critical — synthesis born of practical experience, one that captures an increasingly widespread phenomenon: the use of foreign structures, often American, presented as instruments of absolute asset protection and tax optimisation, but which, under more rigorous scrutiny, risk failing to deliver on their promises.
To truly understand what lies behind this expression, it is necessary to take a step back and separate what is technically accurate from what is, at times, presented in an oversimplified or, worse, misleading manner.
The premise: the trust is a legitimate instrument
The Trust is not, in itself, an avoidance device. It is a legal instrument recognised even in Italy, used for decades in common law jurisdictions and progressively integrated into civil law systems as well. When properly structured, it can represent an effective solution for genuine needs: from succession planning to the management of complex estates, through to the protection of vulnerable individuals.
The fact that a trust is established in the United States does not automatically imply any irregularity. Certain American jurisdictions offer a flexible regulatory framework that, in specific circumstances, may be consistent with particular wealth planning requirements. But it is precisely here that the first misconception lurks: the belief that geographic location alone can guarantee benefits that, in reality, depend on far deeper factors.
The critical point: the gap between form and substance
The heart of the problem lies not in the instrument itself, but in the way it is constructed and used. In tax matters, there is a principle as simple as it is decisive: what matters is not the legal label, but the underlying economic substance.
The Italian Revenue Agency, like the courts, has for many years moved in this direction. It does not simply verify the formal existence of a trust, but analyses its actual functioning. Who truly makes the decisions? Who controls the assets? Who benefits from the economic results?
When the answers to these questions are inconsistent with the declared structure, the entire arrangement risks being deemed purely nominal.
When the “shield” becomes fictitious
It is at this juncture that the meaning of the expression “sham shield” becomes clear. A trust loses its function when the settlor, having formally transferred the assets, continues in practice to exercise substantial control over them.
This occurs more frequently than one might expect. The trustee exists, but merely follows instructions. Strategic decisions remain in the hands of the settlor. The beneficiaries are already identified and, in many cases, coincide with the immediate family circle. There are even, at times, clauses enabling the structure to be modified or revoked with remarkable ease.
In these situations, the trust risks being regarded as “interposed”: a structure that formally exists, but lacks genuine autonomy. And when this occurs, the consequences are far from theoretical. Income and assets are attributed back to the Italian-resident individual, with all the attendant tax implications.
The myth of the foreign shield
A significant part of the problem stems from a narrative that has found fertile ground in recent years: the notion that a foreign structure — and a US one in particular — can automatically guarantee anonymity, protection, and tax advantages.
This is a dangerous oversimplification.
For an individual who is fiscally resident in Italy, what matters is not so much where the trust is located, but how it is structured and, above all, who exercises effective control over it. The tax residency of the settlor, the location of income, monitoring obligations, and the traceability of financial flows are elements that cannot be circumvented simply by moving a structure across borders.
The idea of the “foreign shield” as a universal solution belongs more to marketing than to legal reality.
The true dividing line
At this point, the fundamental distinction emerges with clarity. There is no opposition between Italian trusts and foreign trusts. There is, rather, a very clear line of demarcation between structures that have substance and structures that merely have form.
A correctly constructed trust entails a genuine transfer of assets, a trustee endowed with decision-making autonomy, and a coherent and defensible purpose. It is not an instrument designed to “disappear”, but to organise and manage assets in a sophisticated manner.
By contrast, structures that are created with the primary objective of circumventing tax constraints or generating opacity tend to be inherently fragile. And, in time, that fragility will surface.
A problem of narrative (before it is even a technical one)
The success of many of these solutions is not coincidental. It is grounded in a genuine need — the protection of one’s estate — but addresses it with a simplistic response.
Promises of total protection, zero taxation, guaranteed anonymity. It is a language that reassures, but that rarely finds confirmation in the complexity of modern tax systems.
The risk for the investor or the family is not merely that of adopting an ineffective structure. It is, above all, the risk of developing a false sense of security. And when perception diverges from reality, the consequences can be significant.
In conclusion
To speak of the “sham shield US trust” is, ultimately, to draw attention to a crucial issue: the difference between what a structure promises and what it is genuinely able to deliver.
The trust remains a powerful, sophisticated, and in many cases entirely legitimate instrument. But it is not a shortcut. It is not a universal solution. And, above all, it is not a shield by definition.
In an increasingly transparent and interconnected environment, the solidity of a wealth structure does not depend on the jurisdiction chosen, but on its coherence, its credibility, and its capacity to withstand scrutiny over time.
And it is precisely there that the difference between planning and illusion is decided.
