In brief
In two recent and closely aligned judgments (number 167/2026, of 17 February, and 186/2026, of 19 February), the Spanish Supreme Court has clarified how the family business exemption should be applied to real estate rental activities carried out within corporate groups.
The Court confirmed that, in specific circumstances, the statutory requirement of having a full time employee for real estate rental activities may be satisfied at group level, even if the employee is not formally hired by the property owning entity.
These decisions reinforce a substance over form approach, aligned with the economic reality of many family owned groups that centralize personnel and management functions, while also setting clear limits to prevent purely formal or passive structures from benefitting from the exemption.
In more detail
Background
Spanish Wealth Tax and Inheritance and Gift Tax provide a coordinated set of incentives aimed at facilitating the continuity of family businesses.
In particular:
- Article 4.8.2 of the Wealth Tax Law grants an exemption for shareholdings in entities that carry out a genuine economic activity; and
- Article 20.6 of the Inheritance and Gift Tax Law allows a 95% reduction on the value of such shareholdings when transferred inter vivos or mortis causa.
Where the activity consists of real estate rentals, Article 27.2 of the Personal Income Tax Law requires, as a general rule, the existence of at least one full time employee dedicated to the management of that activity.
Historically, the Spanish Tax Authorities have applied this requirement in a strict and formalistic manner, often denying the exemption where the employee was not hired directly by the property owning entity, even when the rental activity was clearly managed within a wider group structure.
In depth
A flexible interpretation of the employee requirement
The Supreme Court departed from a purely formal approach and confirmed that, where a real estate rental activity is genuinely integrated within a broader economic activity carried out by a corporate group, the employee requirement may be considered fulfilled even if the employee is formally hired by another group company.
The Court stressed that the decisive factor is not the formal allocation of employment contracts, but whether the rental activity:
- Forms part of a unitary organization of human and material resources at group level, and
- Is functionally integrated into the group’s economic activity, rather than being a standalone or passive asset holding activity.
In the cases analyzed, the property owning companies contributed essential assets (real estate) to a wider business model operated by the group, with personnel, technical services and operational functions provided centrally by other group entities.
Limits to the flexible approach
Importantly, the Supreme Court is equally clear that this flexible interpretation does not apply automatically to all group structures.
The group level approach is only available where the taxpayer can evidence that:
- The real estate rental activity is economically and functionally integrated into the group’s overall activity; and
- The use of group level personnel reflects the actual organization of the business, not merely a formal or artificial arrangement.
Where the rental activity operates independently from the rest of the group, the employee requirement must still be met within the property owning entity itself.
Practical implications for family-owned groups
These judgments provide welcome clarity for many family owned groups that have historically centralized personnel, management and operational functions for efficiency reasons.
From a practical perspective:
- Groups with integrated real estate rental activities may have stronger grounds to apply the Wealth Tax exemption and the 95% Inheritance and Gift Tax reduction.
- At the same time, the focus on economic reality and evidence increases the importance of documenting how rental activities are actually managed within the group.
Structures relying on this case law should be prepared to demonstrate, in the event of a tax audit, that the rental activity is not merely using group resources opportunistically, but is genuinely embedded in the group’s business model.
Conclusions
These rulings confirm a clear trend in Supreme Court case law towards interpretations that:
- Protect the continuity of family businesses;
- Avoid penalizing efficient group wide organization models; and
- Reject excessively formalistic readings of tax requirements.
However, the line between an integrated business activity and a passive real estate structure remains highly fact specific.
Against this backdrop, family owned groups, particularly those approaching succession planning or contemplating inter vivos reorganizations, should reassess their real estate holding and management structures to ensure they are aligned with the criteria now confirmed by the Supreme Court.
