Liechtenstein and Swiss Foundations: A 2026 Reassessment for LatAm Families

Liechtenstein and Swiss Foundations: A 2026 Reassessment for LatAm Families

In the 2026 fiscal environment, the use of classic wealth structures like the Liechtenstein foundation (Stiftung) and the Swiss foundation (Stiftung) by Latin American families demands a strategic reassessment. The full implementation of the Common Reporting Standard (CRS) and the sustained tightening of anti-deferral regimes in key Latin American jurisdictions, such as Colombia's Controlled Foreign Corporation (CFC) regime amended by Law 2277 of 2022, have transformed the analysis. What once centered on confidentiality and tax deferral now focuses on governance, economic substance, and the structure's ability to withstand the scrutiny of increasingly sophisticated tax administrations. The debate is no longer about whether to establish a foundation, but whether existing structures are defensible under current regulations.

The premise of wealth planning has decisively pivoted. The era of opacity has been closed by a global network of automatic information exchange. For families with assets in Latin America, this means that the existence of a foundation in Europe and its financial balances are, with high probability, known to their local tax authority. The structure's value, therefore, no longer lies in secrecy, but in its correct legal and fiscal characterization that prevents a direct and immediate attribution of its assets and income to the founder or beneficiaries, according to the rules of their country of residence.

Current Scrutiny: Substance and Control

The central challenge in 2026 for a European foundation holding assets for a Latin American family lies in two concepts: control and substance. Modern tax legislation, especially that which follows OECD guidelines on BEPS, is designed to neutralize tax deferral through low or no-tax entities. A foundation's effectiveness depends on its ability to be recognized as a separate and independent entity from its founder.

For Colombia’s CFC regime, for example, established by Law 1819 of 2016 and whose application thresholds are consistently reviewed, an entity is 'controlled' if one or more Colombian tax residents hold, directly or indirectly, a stake of more than 50%. In the case of foundations and other non-capital participation structures, the rule looks to the reality of effective control. If the founder residing in Colombia retains the de facto power to direct investments, modify beneficiaries at their discretion, or revoke the structure, the tax administration (DIAN) will argue that control exists. The consequence is the attribution of the foundation's passive income (interest, dividends, royalties) to the founder, regardless of whether it has been distributed.

To counter this presumption, the foundation's governance must be impeccable and demonstrable. The foundation council must operate with real independence. This entails having qualified and, preferably, independent members in Liechtenstein or Switzerland, holding documented meetings in that jurisdiction, and making investment and distribution decisions based on the foundation's statutes, not on direct and informal instructions from the founder. 'Letters of wishes', while a valid instrument, must be non-binding and drafted with extreme caution so as not to be interpreted as a tool of direct control.

Furthermore, economic substance is crucial. Although a wealth management foundation does not require an industrial operation, concepts derived from proposals like the EU's ATAD 3 'Unshell' directive have permeated the thinking of tax auditors globally. The entity must have a physical address, qualified personnel for its management (even if through a professional corporate service provider), and its own bank accounts. The absence of these elements facilitates the argument that the foundation is a mere artifice with no genuine economic purpose.

Comparative Analysis: Liechtenstein vs. Switzerland in the LatAm Context

While both jurisdictions offer robust vehicles, they present significant differences that impact their suitability for Latin American families in the current scenario.

The Liechtenstein private foundation (private Stiftung), regulated by its Persons and Companies Act and reformed by the 2011 Tax Act, offers considerable flexibility. It allows the founder a high degree of influence in drafting the statutes and supplementary by-laws, precisely defining governance and beneficiary rights. If structured as a Private Asset Structure (Privatvermögensstruktur or PVS), it does not conduct economic activity and is subject only to a minimum corporate income tax. This low effective taxation is precisely what triggers CFC regime alarms. Therefore, the defense of a Liechtenstein Stiftung in 2026 is not based on the tax it pays at source, but on demonstrating the founder's loss of control.

The Swiss foundation (Stiftung), on the other hand, is perceived as a more traditional and rigid structure. It is subject to mandatory supervision by a federal or cantonal authority, which lends it a seal of legitimacy and institutional stability but drastically reduces the founder's flexibility and control once established. Swiss family foundations, intended to cover education or maintenance costs for family members, may enjoy tax exemptions under strict conditions, but their use for the dynamic management of global investment assets is more complex. Its strength lies in its reputation and the clarity of its supervision, which can be a powerful argument against a tax authority questioning its independence.

For a Latin American family, the choice is not trivial. Liechtenstein's flexibility may be attractive, but it requires extraordinary governance discipline to avoid being classified as 'controlled'. Switzerland's rigidity may offer a more solid defense against income attribution, but at the cost of ceding significant control from the outset. In both cases, the irrevocable nature of the asset contribution is a fundamental prerequisite to argue that the assets have legally exited the founder's sphere.

Strategic Implications and Recommendations

For advisors to family offices and private wealth in 2026, the primary task is the audit and stress-testing of existing structures. A rigorous diagnosis of each foundation must be carried out in light of the legislation of the founder's and beneficiaries' country of residence. This analysis must question whether the level of retained control crosses the line established by CFC rules or similar regulations, and whether the entity's substance and governance are documentable and defensible.

The strategy to follow may range from making adjustments to the foundation's statutes and council composition, to transferring management to a fully independent professional trustee. In extreme cases, where the original structure was designed under outdated confidentiality paradigms, it may be necessary to consider an orderly restructuring or even the liquidation of the entity to repatriate the assets into a structure that is fully compliant with the current tax transparency environment.

Liechtenstein and Swiss foundations remain powerful tools for long-term asset succession and protection. However, their purpose has been redefined by the global regulatory environment. Their value is no longer tax deferral, which is increasingly difficult to sustain, but structured governance, protection against political or family instability, and orderly succession planning, all within a framework of full tax compliance.
