The Central Economic Administrative Court (Tribunal Económico-Administrativo Central, TEAC) has delivered a decision of major significance for international private wealth planning involving Spanish assets. In Resolution 00/02959/2023/00/00 of 24 September 2025, classified as doctrine, the TEAC expressly changes its prior administrative criterion and confirms that taxpayers resident in third countries outside the European Union may apply the Wealth Tax legislation of the Autonomous Community in which the majority of their Spanish assets are located, even for tax years prior to the entry into force of Law 11/2021.
The decision represents a decisive step in aligning Spanish Wealth Tax practice with European Union law on the free movement of capital and resolves a long standing area of uncertainty for non EU high net worth individuals.
1. Background and scope of the dispute
The case concerns Spanish Wealth Tax (Impuesto sobre el Patrimonio, IP) for tax year 2020. The taxpayer was an individual resident in a non EU country who held assets and rights located in Spain. The majority of those assets were situated in a specific Autonomous Community whose regional Wealth Tax legislation provided for a 100 percent relief on the tax due.
The taxpayer filed his Wealth Tax return as a non resident subject to real liability and paid tax under the state rules applicable to non residents. Subsequently, he requested rectification of his self assessment, arguing that he should have been entitled to apply the autonomous community legislation, which would have resulted in a full relief of the tax.
The Spanish Tax Agency, through the National Tax Management Office (ONGT), rejected the request on the basis that, under the wording of the Fourth Additional Provision of the Wealth Tax Law (Law 19/1991) applicable in 2020, only non residents resident in the EU or EEA were entitled to apply regional legislation.
2. Taxpayer’s position and arguments relied upon
The taxpayer argued that the differential treatment between EU or EEA residents and residents of third countries constituted an unlawful restriction on the free movement of capital contrary to article 63 of the Treaty on the Functioning of the European Union (TFEU).
He relied on consolidated case law of the Court of Justice of the European Union (CJEU), as endorsed by the Spanish Supreme Court, confirming that the freedom of movement of capital extends to transactions and situations involving third countries. In support of this position, he cited, among others, Supreme Court judgments 488/2018 and 492/2018, as well as judgment 396/2022 of the High Court of Justice of the Basque Country, which had already allowed a non EU resident to apply autonomous community Wealth Tax rules.
The taxpayer further argued that the legislative amendment introduced by Law 11/2021 did not create a new right, but merely codified a legal position that was already required under EU law.
3. Position of the Tax Authorities
The Tax Authorities rejected the rectification request and upheld the assessment. Their position was that:
The wording of the Fourth Additional Provision of the Wealth Tax Law in force in 2020 expressly limited access to autonomous community legislation to non residents resident in the EU or EEA.
The amendment introduced by Law 11/2021, which extended this right to all non residents, only entered into force on 11 July 2021 and could not be applied retroactively.
As a result, the taxpayer was correctly taxed under the state rules applicable to non residents for the 2020 tax year.
4. The legal issue before the TEAC
The TEAC framed the dispute as a question of whether the domestic provisions relied upon by the Tax Authorities should be applied as written, or whether they should be set aside because they were contrary to directly applicable EU law.
In particular, the Tribunal had to determine whether, notwithstanding the absence of formal retroactivity of Law 11/2021, the principles derived from article 63 TFEU and the jurisprudence of the CJEU required the autonomous community legislation to be applied to non EU residents for earlier tax years.
5. Obligation of economic administrative bodies to apply EU law
A central element of the TEAC’s reasoning is its express acknowledgement that economic administrative bodies are obliged to guarantee the effective application of EU law.
Relying on settled CJEU case law, including the Costanzo doctrine and judgment C-274/14, the TEAC recalls that all national authorities, not only judicial bodies, must disapply domestic provisions that are contrary to EU law where those EU provisions have direct effect. This obligation applies even where the national authority is not competent to refer a preliminary question to the CJEU.
The TEAC further notes that both its own prior decisions and the Spanish Supreme Court have consistently recognised this duty of administrative self correction in order to safeguard rights conferred by EU law.
6. Extrapolation of CJEU doctrine from Inheritance Tax to Wealth Tax
The Tribunal expressly addresses the argument that the relevant CJEU case law originally concerned Spanish Inheritance and Gift Tax. It rejects any suggestion that applying that doctrine to Wealth Tax would amount to prohibited analogy under article 14 of the General Tax Law.
Instead, the TEAC endorses the position taken by several High Courts of Justice, including the Basque Country and Asturias, which have confirmed that the underlying rationale of the CJEU’s case law applies equally to Wealth Tax. In both cases, the discriminatory factor is the taxpayer’s place of residence, and in both cases the discriminatory effect is capable of restricting the free movement of capital.
The Tribunal emphasises that there is no legal justification for accepting such discrimination in Inheritance Tax while tolerating it in Wealth Tax.
7. Express change of administrative doctrine
Having set out the applicable legal framework, the TEAC concludes that, although the Fourth Additional Provision of the Wealth Tax Law as amended by Law 11/2021 is not formally retroactive, the doctrine of the Supreme Court and the jurisprudence of the CJEU that prompted that amendment were already applicable at the time of the Wealth Tax accrual for 2020.
As a result, the TEAC holds that the version of the Fourth Additional Provision in force in 2020 must be disapplied insofar as it excludes residents of third countries from the application of autonomous community legislation.
The Tribunal expressly states that this conclusion modifies its prior criterion, as reflected in its resolutions of 12 December 2024, which had rejected the application of regional legislation to non EU residents in identical cases.
8. Decision and consequences
The TEAC upholds the taxpayer’s claim in full, annuls the contested administrative act and confirms that the taxpayer, despite being resident in a third country, is entitled to apply the Wealth Tax legislation of the Autonomous Community in which the majority of his Spanish assets are located.
In the specific case, this resulted in the application of a 100 percent relief and the elimination of the Wealth Tax liability for the year under review.
9. Practical implications for international private wealth planning
This resolution has immediate and far reaching implications for non EU individuals with Spanish Wealth Tax exposure:
Non EU residents who have paid Spanish Wealth Tax in prior open years without applying autonomous community legislation may have grounds to seek rectification and refunds.
The decision confirms that EU fundamental freedoms must be taken into account even where the taxpayer is resident outside the EU, provided that capital movements are affected.
For structuring purposes, the geographic allocation of assets within Spain and their concentration in specific Autonomous Communities remains a critical planning factor.
More broadly, the ruling reinforces the need for wealth structures involving Spain to be reviewed not only in light of domestic tax law, but also through the lens of EU law and its direct effect.
10. Conclusion
The TEAC’s Resolution of 24 September 2025 represents a clear and authoritative shift in Spanish administrative doctrine. By recognising the right of non EU residents to apply autonomous community Wealth Tax rules on the basis of directly applicable EU law, the Tribunal removes a source of structural discrimination and brings Wealth Tax practice into line with established European jurisprudence.
For internationally mobile high net worth individuals and family offices, the decision underscores the importance of proactive, legally sophisticated wealth planning that anticipates the interaction between Spanish tax law and European Union principles, even where the taxpayer’s residence lies outside the EU.
