Spain's Supreme Court establishes rules on the VAT deductions by mixed holding companies

The Supreme Court has ruled that the transfer of shares by a mixed holding company constitutes an autonomous financial activity forming a separate sector for Value Added Tax (VAT) purposes, with restrictive effects on deduction.

Judgment No. 308/2026 of 11 March 2026 (appeal No. 4660/2023) analyses the VAT treatment of intra-group transfers of shareholdings by mixed holding companies and establishes important criteria on the deduction regime and the application of the pro rata rule.

The ruling is of particular importance for business groups and holding companies that combine management and intra-group service provision activities with financial activities linked to the acquisition, holding and transfer of shareholdings.

Origin of the dispute

AEAT, the Spanish tax agency, initiated an audit of a business group to verify the correct deductibility of input VAT during the periods between November 2011 and December 2012.

The inspectorate observed that the parent company was deducting 100% of the input VAT without applying either the pro rata rule or the separate sectors regime, despite carrying out activities that were treated differently for tax purposes.

According to the tax authorities, the company was simultaneously carrying out two distinct activities. The first was a service provision activity for subsidiaries, consisting mainly of management support and cost re-invoicing. The second was a financial activity consisting of the granting of loans and guarantees, as well as the acquisition, holding and transfer of shareholdings.

The tax inspectorate concluded that these activities were of a different nature, were not ancillary to one another and had deduction rates that differed by more than 50 percentage points. The differentiated sectors regime provided for in the VAT Act should therefore have been applied.

Tax authorities' classification

After analysing the group’s structure and its intra-group operations, the tax authorities classified the parent company as a mixed holding company.

The Supreme Court also started from this premise and pointed out that a mixed holding company is not limited to the mere passive holding of shares, but actively intervenes in the management of its subsidiaries by providing services subject to VAT.

However, the chamber emphasised that this active involvement does not preclude the existence of an autonomous financial activity where the entity habitually carries out financing operations, grants guarantees or buys and sells shareholdings.

In this regard, the court rule that the acquisition, holding and transfer of shares constitutes a financial activity for VAT purposes and must form a distinct sector of activity.

The court attached particular importance to several factors: the repetition and regularity of the transactions; their link to the group’s strategic decisions;  the use of the group’s own organisational resources; and the existence of functional autonomy with respect to the provision of services.

On this basis, it concluded that these transactions constitute a “direct, permanent and necessary extension” of the activity carried out by the holding company, and therefore the transfer of shareholdings does not constitute an ancillary activity.

However, the appellant company argued that the so-called “portfolio activity” should be integrated into the main activity of supporting the group’s management. It further contended that the intra-group transfer of shareholdings was part of a one-off corporate reorganisation and not a genuine autonomous financial activity.

The Supreme Court rejected this argument. The chamber considered that the management and transfer of shareholdings has its own substantive nature, responds to independent business decisions and constitutes a routine activity within the ordinary operations of a mixed holding company.

It also noted that the ancillary nature of such activities cannot be determined solely by a quantitative criterion linked to the volume of transactions, but that the economic function of the activity and its relationship with the group’s organisational and strategic structure must also be analysed.

The chamber found that intra-group financing, the granting of guarantees and the transfer of shareholdings form part of an ongoing business strategy and cannot be classified as isolated or occasional transactions. These activities must therefore be included in the financial sector and taken into account in the calculation of the VAT apportionment.

Deduction limits

The main practical consequence of the ruling is the restriction on the right to deduct input VAT in mixed holding structures.

The tax authorities applied a 98% apportionment for the provision of services, a 0% apportionment for financial activities, and a common apportionment of 55% for shared expenses.

The Supreme Court endorsed this approach and confirmed that exempt financial activities must be assessed separately where they possess autonomy and substance within the business organisation.

The ruling thus consolidates a restrictive line of case law regarding the right of mixed holding companies to deduct input VAT.

Economic unit

The appellant also argued that the transfer of shares indirectly involved the transfer of an autonomous economic unit and that, therefore, it should be considered a transaction not subject to VAT in accordance with article 7.1 of the VAT Act.

The Supreme Court accepted this in principle. The chamber acknowledged that an intra-group transfer of shares may be exempt from VAT where it indirectly involves the transfer of an economic unit capable of carrying out a business activity by its own means. However, it rejected its application to the specific case.

The court found that sufficient material and human resources were not transferred to carry out an economic activity autonomously and noted that the acquiring entity already possessed the necessary know-how and resources to manage the business. There was therefore no transfer of a genuine autonomous economic unit.

Osborne Clarke comment

The Supreme Court’s ruling reinforces the tax authorities’ position regarding the VAT treatment of mixed holding companies.

The ruling confirms that the acquisition, holding and disposal of shareholdings constitute an autonomous and distinct financial activity where they form part of the holding company’s business strategy and ordinary course of business, significantly limiting the possibility of treating these transactions as ancillary or irrelevant for the purposes of the pro rata rule.

This ruling has significant implications for mixed holding structures. We believe that holding companies should review how this doctrine affects their structures and adapt them where necessary to optimise the applicable VAT deduction regime.
