The tax regime of Law 49/2002 does not apply automatically to non-resident foundations: the TEAC requires the prior election to exclude taxation under the IRNR

The Central Economic-Administrative Tribunal, in its decision of 19 February 2026 (First Chamber, claim no. 7969/2022), reiterates a doctrine relevant to international wealth structuring through foreign foundations. The special tax regime for non-profit entities provided for in Law 49/2002 —which provides, among other advantages, the exemption of capital gains derived from gratuitous acquisitions— does not apply automatically. It requires the entity to opt into it expressly by filing the relevant census declaration. A non-resident foundation that receives real estate in Spain by inheritance and that has not opted into the regime is taxed, without exemption, under the ordinary rules of the Non-Resident Income Tax (IRNR).

It is helpful to begin with the legislative framework, because the interplay between taxes is the key to the dispute.

Where a natural person receives real estate in Spain by way of gratuitous transfer —by inheritance or by gift— the taxation corresponds, as a general rule, to the Inheritance and Gift Tax (ISD), whose taxpayer is the recipient natural person, resident or non-resident. The ISD, however, does not apply to gratuitous acquisitions made by legal persons: these fall outside the inheritance tax.

The consequence is a shift to income tax. For resident legal persons, the gratuitous acquisition is taxed under the Corporate Income Tax as a change in net worth. For non-resident legal persons —including foreign foundations— the acquisition is taxed under the IRNR as a capital gain, in accordance with article 13.1.i), paragraphs 3 and 4, of the Consolidated Text of the Non-Resident Income Tax Act (TRLIRNR), approved by Royal Legislative Decree 5/2004. The chargeable event, in accordance with article 27 of the TRLIRNR, takes place with the change in net worth itself.

That said, Law 49/2002, on the tax regime of non-profit entities and on tax incentives for patronage, provides for a special regime which, where its requirements are met, exempts from taxation the income derived from gratuitous acquisitions, provided they are made in pursuit of its specific object or purpose (article 6.2). The central question of the claim under review is whether that regime applies automatically to non-resident foundations or requires, also for them, compliance with the formal requirements that Law 49/2002 itself and its implementing regulation (Royal Decree 1270/2003) impose on resident entities.

The case under review reflects a typical structure in the field of private wealth. A British foundation (XZ UK) received, by inheritance, 50% of a real-estate property located in Spanish territory on 28 January 2020, under a deed of allocation of estate, with a value of its share of EUR 66,000. The foundation did not file an IRNR self-assessment (Form 210) on the capital gain derived from the gratuitous acquisition.

AEAT’s National Office of Tax Management opened a limited verification procedure and issued a provisional assessment. The administrative reasoning was articulated in four steps.

First, the gratuitous acquisition by a legal entity is not subject to the Inheritance and Gift Tax, since the ISD applies only to natural persons.

Second, the same acquisition is taxed under the IRNR as a capital gain, in accordance with articles 13.1.i) 3 and 4 and 27 of the TRLIRNR. The tax treaty entered into between Spain and the United Kingdom —in its articles 3, 6 and 13— attributes to the Spanish State the power to tax real-estate gains.

Third, the tax benefits provided for in the special regime of Law 49/2002, including the exemption of gratuitous acquisitions, are elective in nature: they require prior notification of the election —to the “competent Ministry”, in the words of the decision— and compliance with the legal and regulatory requirements.

Fourth, XZ UK obtained a tax identification number in Spain in 2011, but never sought registration for the special regime. Accordingly, the tax benefits were not applicable.

The foundation filed a request for reconsideration and, this having been dismissed, brought an economic-administrative claim before the TEAC alleging that the non-application of the regime amounted to discrimination contrary to EU law on account of its non-resident status.

The TEAC dismisses the claim and consolidates a doctrine grounded on two considerations that warrant detailed treatment.

First, the election for the tax regime of Law 49/2002 is voluntary and necessary. It does not apply automatically by virtue of the entity meeting the characteristics or substantive requirements of a non-profit entity. The application is conditioned upon an act of will expressed through the relevant notification —to the “competent Ministry”, as the TEAC puts it—, which article 1(1) of the Regulation (Royal Decree 1270/2003) frames as a census declaration filed with the tax authorities. The fact that this is not an application subject to authorisation does not prevent the election from being an act of will on which the actual application of the regime depends: once notified, the regime applies until the entity waives it, without prejudice to the Administration’s subsequent verification power.

Second, the requirement of prior election does not discriminate against non-resident entities. No Spanish non-profit entity applies the regime without the prior express election. The non-application to XZ UK responds to the failure to comply with the same formal requirement that applies to any Spanish entity in the same situation. There is therefore no discrimination on grounds of residence.

The TEAC reiterates the criterion laid down in its decisions of 25 November and 18 December 2025 (claim numbers 5083/2022 and 3724/2022, respectively), so the criterion can be regarded as settled.

In our view, the doctrine of the TEAC is coherent with the logic of the regime. Law 49/2002 articulates a tax benefit of a subjective nature subject to administrative control, which requires by its very nature a clear manifestation of will by the entity and compliance with the formal requirements that allow its appropriateness to be verified. The requirement of prior election is reasonable and does not impose on non-resident entities a burden different from that which falls on Spanish entities.

Subject to the foregoing, the doctrine leaves open two routes of action for non-resident foundations with wealth ties in Spain. The first, anticipated election for the regime, which is only available to entities resident in the EU or the EEA (article 2.g) of Law 49/2002) or operating in Spain through a permanent establishment (article 2.f), where the foundation foresees the future acquisition of assets or rights in Spanish territory by way of gratuitous transfer. The second, prior planning of the legal structure of the operation, assessing whether it is appropriate to channel the acquisition through a resident entity that already enjoys the regime or through alternative figures with more favourable tax treatment.

The practical consequence is highly relevant for family groups with cross-border ties who channel their real-estate holdings in Spain through foreign foundations —Liechtenstein Stiftung, Austrian Privatstiftung and analogous EEA vehicles—. Gratuitous contributions, inheritances or gifts of real estate, or of undivided shares, to this type of vehicle are taxed in Spain as capital gains subject to the IRNR if no election has been made.

For foundations from Panama, Curaçao or, post-Brexit, the United Kingdom, the position is even more restrictive: they cannot opt into the regime unless they operate in Spain through a permanent establishment. In the case decided, the acquisition took place on 28 January 2020, when the United Kingdom was still a Member State, so XZ UK could have opted; today, a British foundation without a permanent establishment could not.

For defensive and planning purposes, it is advisable to review the foundation’s tax registration position in Spain before any operation involving gratuitous acquisition of assets in Spanish territory. If the foundation substantively meets the requirements of Law 49/2002 and wishes to opt into the special regime, the election must be made by filing the relevant census declaration with the tax authorities (article 1(1) Royal Decree 1270/2003), together with the associated information obligations. The regime applies to the tax period ending after that declaration and, for taxes without a tax period, to chargeable events occurring during that period (article 1(2) and (3)). In our view, once the tax period in which the acquisition took place has closed, the election can no longer reach it.

In conclusion, what this TEAC decision makes clear is that the special tax regime of Law 49/2002 does not apply automatically to non-resident foundations: it requires an express election, available only to EU and EEA entities or to those operating through a permanent establishment, and its non-application where that election has not been made does not constitute discrimination contrary to EU law, since non-resident and resident entities are governed by the same formal requirement.
