The Spanish Supreme Court, in its Judgment 167/2026, of 17 February 2026 (cassation appeal 1196/2024), has laid down doctrine on a question that frequently arises in family groups. The issue is whether a company that leases out property and has no employees of its own carries on a business activity when the management of its leases is carried out by staff of other companies in the group.

The answer is yes, but subject to a condition that must be read carefully. It is not enough to belong to the group or to make use of its staff. The lessor’s activity must be functionally integrated into a business activity of the group that goes beyond mere leasing.

The facts

In December 2014, two parents gave several of their children shares in the head company —that is, the holding company at the top of the group— of a family group from Murcia. The donees applied, for Gift Tax purposes, the 95 per cent reduction provided for the inter vivos transfer of a family business.

Among the head company’s subsidiaries was a company, 73.80 per cent owned, whose activity consisted of leasing rural land —in some cases with irrigation head units— and which had no employee under a labour contract. The regional tax inspectorate took the view that this subsidiary did not carry on a business activity. Consequently, the head company’s shareholding in it, valued at EUR 5,409,000, became a non-qualifying asset, that is, an asset that is not used in a business activity and that, for that reason, cannot benefit from the exemption.

The inspectorate also excluded the shareholding in another subsidiary, which it classified as a wealth-holding entity. The result was that only 74.67 per cent of the value of the shares given was considered eligible for the reduction. The assessment amounted to EUR 5,882.21. The Regional Economic-Administrative Court of Murcia and the High Court of Justice of that region upheld the inspectorate’s position.

The regulatory framework: three linked provisions

To understand the judgment, it is necessary to bear in mind the chain of cross-references on which this tax benefit rests.

Article 20.6 of Act 29/1987, of 18 December, on Inheritance and Gift Tax (LISD), reduces by 95 per cent the tax base of a gift of shares in favour of the spouse or descendants, provided that those shares qualify for the exemption in article 4.Ocho of Act 19/1991, of 6 June, on Wealth Tax (LIP), which takes family businesses and shareholdings in entities meeting certain requirements outside the scope of that tax.

Article 4.Ocho.Dos.a) LIP, in turn, excludes from the exemption entities whose main activity is the management of movable or immovable assets. To determine whether a business activity exists, or whether an asset is used in it, it refers expressly to the Personal Income Tax legislation.

It is at that point that article 27.2 of Act 35/2006, of 28 November, on Personal Income Tax (LIRPF), comes into play. This provision states that the rental of immovable property is only considered a business activity where at least one person employed under a labour contract and on a full-time basis is used for its management. In the wording in force at the date of the gift, premises used exclusively for managing the activity were also required, a requirement that disappeared with effect from 1 January 2015. The Administration, however, only challenged the absence of an employee.

Note, moreover, that article 5.1 of Act 27/2014, of 27 November, on Corporate Income Tax, does provide that, in groups of companies within the meaning of article 42 of the Commercial Code, the business activity is to be determined taking into account all the entities in the group. The LIRPF contains no equivalent rule and, as the Chamber itself acknowledges, could not contain one, because its taxpayer is the individual. Furthermore, article 5.1 of Act 27/2014 entered into force on 1 January 2015, after the gift.

The parties’ positions

The appellant argued that the concept of business activity, in the case of shareholdings in entities, should be supplemented by the Corporate Income Tax group rule, to which it attributed a clarifying value. It alleged that the leasing subsidiary used the personal and material resources of the group as a whole: administrative, technical and financial departments, and full-time staff.

The State Attorney’s Office defended a strict reading of the cross-reference. The LIP refers to Personal Income Tax and not to Corporate Income Tax; article 27.2 LIRPF is a specific rule for rental, and the employee must be in the leasing company itself.

The Supreme Court’s reasoning

The Chamber frames the debate differently. In its view, what matters is not whether or not the subsidiary has an employee on its payroll, but whether its activity can be analysed in isolation, as mere leasing, or whether it forms part of a broader business activity of the group.

To answer, the Court relies on the very facts recorded in the inspection report. The lease agreements for the land required the tenants to contract complementary services with other group companies: one of them collected the water charge and another provided the qualified technicians and the irrigation labourer. Of the group’s average of 41.32 employees, two were directly involved in managing the subsidiary’s leases, although they were employed by two other group companies.

In the light of this, the Chamber concludes that the subsidiary contributed the land, an indispensable element, to an agricultural activity organised across the group as a whole. Its activity, therefore, went beyond mere leasing.

The Court expressly accepts that, if the subsidiary merely leased out property, it would make full sense to apply article 27.2 LIRPF on its own terms. The employee requirement, it recalls, is intended precisely to prevent the family-business benefit from extending to passive activities that merely make property available to third parties in exchange for rent.

On that basis, the Chamber holds that the LIP’s cross-reference to Personal Income Tax should not be applied mechanically and formalistically, because what the Wealth Tax rule seeks is the existence of a real business activity. In support of this teleological interpretation —that is, one attentive to the purpose of the rule— it invokes its judgment of 14 July 2025 (cassation appeal 2197/2023), as well as the Commission Recommendation of 7 December 1994 on the transfer of small and medium-sized enterprises and the European Parliament resolution of 8 September 2015 on family businesses. Neither of these two European texts is binding, but the Chamber uses them as interpretative context for the tax benefit.

The doctrine laid down

The cassation doctrine is formulated in the following terms. Where the leasing entity belongs to a group of companies with a business activity —within the meaning of article 42 of the Commercial Code and article 5.1 of Act 27/2014— and the management of the leasing is carried out with personal and material resources of the group, even if centralised in other companies, the full-time employee requirement in article 27.2 LIRPF must be regarded as met.

That effect is conditional on what the Chamber itself calls the decisive criterion: that there is a unity of resources and activity across the group and that the lessor is functionally integrated into that activity. In other words, the lessor must serve the group’s business activity, and not simply make use of its resources.

Where that condition is met, the holding company’s shares in the subsidiary are qualifying assets and are not counted as non-qualifying for the purposes of the proportionality rule in the last paragraph of article 4.Ocho.Dos LIP. This rule limits the exemption, and with it the reduction, to the part of the value of the shares that is proportionate to the assets used in the entity’s business activity.

Conversely, the Chamber makes clear that the doctrine does not apply if there is only formal membership of the group, without functional and economic integration of the leasing with the activity of the other companies. In that case, the requirements of article 27.2 LIRPF must be evidenced on a stand-alone basis in the lessor itself.

In the case at hand, the Supreme Court upholds the appeal, quashes the lower court’s judgment —that is, sets it aside— and annuls the assessment. The shareholding in the lessor is a qualifying asset. So too, according to the Chamber, is the shareholding in the other subsidiary excluded by the inspectorate, which in turn held shares in the lessor. The 74.67 per cent proportion thus disappears and the 95 per cent reduction must be applied to the entire value.

Relationship with the Judgment of 14 July 2025

The Chamber itself distinguishes this judgment from that of 14 July 2025 (Judgment 956/2025, cassation appeal 2197/2023). That ruling, handed down in respect of the mortis causa reduction in article 20.2.c) LISD, resolved a different question: whether, once the premises and employee requirements of article 27.2 LIRPF were met, the Administration could also require the hiring to be justified from an economic standpoint. The Court answered no, and held that it is sufficient to evidence compliance with those requirements.

In the words of Judgment 167/2026, in 2025 the debate concerned the sufficiency of the requirements of article 27.2 LIRPF; the debate now is whether they are indispensable in the leasing company itself. The two judgments share the same interpretative starting point, namely the purpose of the family-business benefit, but they do not resolve the same problem.

Our view

We consider that the judgment resolves the specific case reasonably. Where the subsidiary is, in reality, the asset-holding piece of an integrated agricultural business, denying the reduction because the workers who manage its contracts are on the payroll of another company in the same group reflects a formal reading that has little to do with the purpose of the benefit.

That said, we understand that the scope of the doctrine is more limited than its wording might suggest on a first reading. Three aspects call for clarification.

The first is that the judgment does not establish that the employee of any group company serves for all the lessors in the group. The Chamber requires a group business activity that transcends leasing and into which the lessor is integrated as a functional piece. Moreover, it expressly warns that, if the subsidiary’s only activity were leasing, article 27.2 LIRPF would apply on its own terms.

For that reason, the application of this doctrine to a group whose only activity is real estate —several leasing companies and a service company that concentrates the staff— does not clearly follow from the judgment. In that scenario, the risk that the Administration will continue to require an employee in each lessor seems to us, at the very least, medium. The doctrine’s formula, according to which the lessor must serve “the business activity of the group or of the companies whose personal resources support it”, admits broader readings.

The Supreme Court itself has reiterated this doctrine in judgments 186/2026, of 19 February (cassation appeal 1326/2024), and 196/2026, of 20 February (cassation appeal 1143/2024), and in that of 2 March 2026 (cassation appeal 1417/2024). The Spanish Central Economic-Administrative Court (TEAC), for its part, has adopted it in its resolution of 20 March 2026 (RG 00/06015/2024), expressly changing its previous criterion. It has done so, however, by reproducing the same formula, so that the doubt about exclusively real-estate groups remains open.

The second aspect is a technical tension in the reasoning. The LIP refers to Personal Income Tax, and the Chamber itself acknowledges that the LIRPF cannot contain a concept of group of companies. However, the doctrine is formulated by reference to article 5.1 of Act 27/2014, which was neither applicable ratione temporis —that is, by reason of the date on which the tax accrued, prior to its entry into force— nor is it the provision to which the LIP refers. The solution thus rests on a teleological interpretation of the tax benefit. That is a legitimate basis, but it makes the doctrine highly dependent on the facts of each case.

The third is minor. In a passage of the seventh legal ground, the judgment makes the relevance of the group conditional on it “distorting” the reality of the organisation of resources. From the context, we understand this to be a slip and that the intended meaning is the opposite, namely that integration into the group should not distort that organisation of resources.

Practical consequences

For family groups with leasing companies that have no staff of their own, the judgment opens a line of defence, but it requires evidence. In the case decided, the decisive elements came from the inspection report itself, which will not always be the case.

To that end, we recommend reviewing and documenting, prior to any gift or succession planning: (i) the group business activity into which the lessor is integrated and its role in it, beyond the mere letting of property; (ii) the contracts, intra-group and with third parties, that show that articulation, as occurred in the case decided with the complementary services that tenants had to contract with other group companies; and (iii) the identity, dedication and employing company of the persons who actually manage the leases.

If the lessor does not form part of a group activity of this kind, the prudent course remains for it to meet the requirement of article 27.2 LIRPF on its own, with one person employed under a labour contract and on a full-time basis.

The judgment is, moreover, of interest beyond Gift Tax. The doctrine is formulated on article 4.Ocho.Dos LIP, so it is also relevant to the Wealth Tax exemption for shareholdings and to the mortis causa reduction in article 20.2.c) LISD, which refers to the same exemption.

The same can be said of the regional reductions built on that provision. Thus, Act 3/2026, of 30 June, on Support for Family Businesses, of the Community of Madrid, has introduced, with effect from 1 July 2026, its own 99 per cent reduction for the inter vivos and mortis causa acquisition of shareholdings in entities, incompatible with the State reduction. Among its requirements, it retains the condition that the entity’s main activity must not be the management of movable or immovable assets, in the terms of article 4.Ocho.Dos.a) LIP. The question resolved by the Supreme Court will therefore remain decisive in that framework too.

In conclusion, what this Supreme Court judgment makes clear is that the employee required by article 27.2 LIRPF need not be on the lessor’s own payroll when the lessor forms part of a real business activity of the group, but that such functional integration will have to be evidenced in each case with specific facts.
