Inheritance tax in Spain: Regulations on international succession

Key Takeaways — Inheritance Tax in Spain for Non-Residents

• EU Regulation 650/2012 governs which country’s law applies to your estate — and you can elect your nationality’s law in your will.
• Non-resident heirs inheriting Spanish assets must declare and pay Spanish ISD regardless of where they live.
• Following ECJ Case C-127/12, non-residents access the same regional tax reductions as Spanish residents.
• The Valencian Community applies a 50% quota reduction for direct-line relatives — a significant advantage over the national scale.
• No bilateral inheritance tax treaty exists between Spain and the United Kingdom — double taxation risk must be actively managed.
• The declaration deadline is six months from the date of death, extendable to twelve months on request.
• A Spanish will, drafted before a Spanish notary, remains the single most effective estate planning tool for foreign asset owners.
• Missing the six-month deadline triggers late-payment interest and surcharges — early legal engagement is essential.

Inheritance tax in Spain for non-residents is one of the most frequently misunderstood obligations facing foreign nationals with assets or family connections in Spain.

Whether you are a British expatriate who retired to Valencia, a UK property investor with a holiday home on the Costa Blanca, or a resident of the United Kingdom who has inherited a Spanish estate from a relative, the rules that apply to you in 2026 are shaped by EU legislation, national tax law and the autonomous community where the assets are located.

Spain’s EU Regulation 650/2012 establishes which jurisdiction governs succession, while inheritance law in Spain determines how the estate is distributed and taxed.

This guide explains how international inheritances in Spain work in practice, what the tax consequences are for non-resident heirs, and how careful estate planning can significantly reduce your exposure.

Which Country’s Law Governs Your Spanish Inheritance?

The starting point for any international inheritance in Spain is determining which jurisdiction’s succession law applies.

This is not a trivial question when the deceased lived in one country, held assets in another, and left heirs spread across several jurisdictions.

The General Principle: Habitual Residence

Under EU Regulation 650/2012 — commonly referred to as the European Succession Regulation or Brussels IV — the law of the country where the deceased had their habitual residence at the time of death governs the entire succession.

Habitual residence is not determined by nationality or passport country alone. It is the centre of life: where the deceased lived on a day-to-day basis, maintained social and family ties, and conducted their principal activities.

A British national who spent the majority of their time in Valencia, held a Spanish residency certificate (TIE) and was registered on the local padrón will most likely have their estate governed by Spanish law — even if they retained British nationality and owned property in England.

According to the Spanish National Statistics Institute (INE), more than 372,000 British nationals were registered as residents in Spain at the start of 2025 — the largest single non-EU nationality group in the country. For this population, cross-border succession is not an exceptional scenario; it is a foreseeable legal reality that demands advance planning.Source: INE, Padrón Municipal de Habitantes, January 2025.

Exceptions: Closer Connections and Choice of Law

EU Regulation 650/2012 provides two important exceptions to the habitual residence rule.

• Closer connections: If the deceased had manifestly closer ties to another country than to their habitual residence — for example, if they had only recently relocated to Spain — the law of that other country may apply instead.
• Express choice of law: A person may choose, in their will, that the law of their nationality governs their succession. A British national living in Spain can therefore elect English law to apply to the distribution of their estate, provided this choice is expressly stated in a valid will.

This choice-of-law provision is a powerful estate planning tool, particularly for British nationals post-Brexit, where England and Wales succession law operates without the forced heirship (legítima) constraints that apply under Spanish law.

Electing a foreign succession law does not exempt you from paying Spanish inheritance and gift tax (Impuesto sobre Sucesiones y Donaciones, ISD) on assets physically located in Spain.

Does EU Regulation 650/2012 Still Apply to British Nationals After Brexit?

This is one of the most common questions raised by British clients with Spanish assets. The answer is nuanced.

Aspect	EU National Heir	British (Non-EU) Heir
Governing succession law	EU Reg. 650/2012 applies fully	Spanish courts apply Reg. 650/2012 to determine applicable law; UK courts apply UK private international law
Choice of nationality law in will	Recognised across all EU member states	Recognised by Spanish courts; UK courts determine recognition independently
Regional ISD reductions	Available since ECJ ruling C-127/12	Also available — ECJ ruling applied regardless of nationality
Double taxation relief	Varies by bilateral treaty	No Spain–UK inheritance tax treaty exists

For British nationals, the absence of a bilateral inheritance and gift tax treaty between Spain and the United Kingdom makes proactive planning essential to avoid being taxed on the same assets in both jurisdictions.

How Inheritance Tax in Spain for Non-Residents Works in 2026

Spanish inheritance and gift tax (ISD — Impuesto sobre Sucesiones y Donaciones) is a devolved tax administered at the autonomous community level. The tax treatment of your inheritance depends on where the assets are located and, in some cases, where the heir is resident.

The distinction between the obligation to declare an inheritance and the obligation to pay ISD is fundamental and frequently misunderstood. In some cross-border situations, an heir must report the inheritance in two countries but only pay tax in one — provided a double taxation agreement applies.

At the national scale, Spanish ISD rates range from 7.65% to 34% before autonomous community reductions are applied. In the Valencian Community, direct descendants in Group I and II benefit from a 50% reduction on the ISD quota — making inheritance significantly less costly than in higher-rate regions such as Catalonia or Asturias.Source: Ley 29/1987, de 18 de diciembre, del Impuesto sobre Sucesiones y Donaciones (BOE); Conselleria d’Hisenda i Model Econòmic, Generalitat Valenciana.

Heirs Who Are Tax Residents in Spain

If you are a tax resident in Spain at the time you receive an inheritance, your obligations depend on whether the inherited assets are located inside or outside Spain.

• Assets in Spain: You declare and pay ISD in the autonomous community where the assets are located, applying that community’s specific reductions, bonuses and allowances.
• Assets outside Spain: You declare the full global estate in Spain and pay ISD under the rules of the autonomous community where you reside. Where the foreign country also taxes the same inheritance, relief may be available under a double taxation treaty or, in its absence, through a unilateral credit in Spain for the amount already paid abroad.

Where no treaty exists and no credit mechanism applies, taxation in two jurisdictions simultaneously is a genuine risk.

Heirs Who Are Non-Residents in Spain

A non-resident heir inheriting assets physically located in Spain must declare and pay ISD in Spain on those Spanish assets.

Following the landmark ruling of the European Court of Justice in Case C-127/12 (European Commission v Kingdom of Spain, 3 September 2014), non-resident heirs — including those living outside the EU, such as British nationals after Brexit — are entitled to apply the autonomous community rules of the region where the assets are located, rather than the less favourable national scale.

This ruling substantially reduced the ISD burden for non-resident heirs and removed a longstanding discrimination between residents and non-residents.

• Assets in Spain: Declare and pay ISD in Spain under the regional rules where assets are situated.
• Assets outside Spain: If the estate is opened in Spain but specific assets are located abroad, no ISD is payable on those foreign assets. An informational declaration may, however, be required.
• Dual declaration risk: If your country of residence also taxes inherited foreign assets and no bilateral treaty applies, you may face taxation in both countries. A partial credit for taxes paid abroad may be claimed in Spain — but it must be actively documented and requested at the time of filing.

Regional Inheritance Tax Across Spain: How the Valencian Community Compares

Because ISD is a devolved tax, the effective cost of inheriting in Spain varies dramatically depending on the autonomous community where the assets are located. The table below summarises the treatment for direct-line heirs across the most relevant regions for foreign nationals.

Autonomous Community	Reduction / Bonus (Group I–II)	Effective Burden	Notes
Valencian Community	50% quota reduction; €100,000 allowance per child; ~€156,000 for spouses	Low-to-moderate	Significantly improved vs national scale; ongoing reform programme
Madrid	99% quota bonus for direct relatives	Near-zero	Among the most favourable regimes in Spain
Andalusia	99% quota bonus (direct relatives, since 2022)	Near-zero	Substantial reform introduced in 2022
Catalonia	Partial reductions; surcharges above thresholds	Moderate-to-high	One of the heaviest ISD regimes in Spain
Balearic Islands	Reductions for direct relatives; reforms ongoing	Low-to-moderate	Popular destination for foreign property owners
National scale (fallback)	No community bonuses; 7.65%–34%	High	Applies only where no community claims jurisdiction

As of 2026, the 50% quota reduction for Group I and II heirs in the Valencian Community remains in force, alongside individual tax-free allowances of €100,000 per child and approximately €156,000 for surviving spouses. These figures are subject to legislative change and must be verified at the time of declaration.Source: Diari Oficial de la Generalitat Valenciana (DOGV); Agencia Tributaria (AEAT).

For investors and families with assets in the Valencian Community, the regional ISD framework represents a meaningful financial advantage — particularly when compared to the national fallback scale or higher-cost regions such as Catalonia.

Deadlines for Declaring an Inheritance in Spain

Time limits for ISD declarations are strict. Non-compliance carries automatic late-payment interest, potential surcharges and — in cases of deliberate non-declaration — sanctions under the Ley General Tributaria.

• Standard deadline: Six calendar months from the date of death.
• Extension: A further six months may be requested from the competent autonomous community tax authority before the initial period expires. No additional fee applies to the extension itself, though interest may accrue if the tax payment is also deferred.
• Plusvalía municipal: Where real property is included in the estate, the municipal capital gains tax declaration must be filed with the relevant town council within six months, extendable to one year.

Under Article 27 of the Ley General Tributaria (Law 58/2003), voluntary late declarations attract surcharges of between 1% and 15% depending on the period of delay, in addition to interest at the current legal rate. Declarations filed more than 12 months after the deadline may additionally be subject to penalty proceedings.Source: BOE-A-2003-23186, Ley 58/2003, de 17 de diciembre, General Tributaria.

For British families managing a Spanish estate from the United Kingdom, the logistical complexity of gathering documents, obtaining apostilled powers of attorney and coordinating with Spanish notaries and the AEAT makes engaging a specialist international inheritance lawyer in Spain from the outset strongly advisable.

The Spain–UK Double Taxation Problem

Unlike income tax — where Spain and the United Kingdom have a comprehensive double taxation agreement — no bilateral treaty exists between Spain and the UK covering inheritance and gift tax.

This structural gap creates a specific risk for British nationals with Spanish assets.

• Spanish ISD: Payable on Spanish-sited assets, with regional rules applied where applicable.
• UK Inheritance Tax (IHT): Payable on worldwide assets above the UK nil-rate band (£325,000 in 2025–26, plus any available residence nil-rate band) where the deceased was UK-domiciled. A Spanish resident can retain UK domicile of origin in certain circumstances, creating a genuine dual-charge scenario.

As of 2026, no bilateral inheritance tax treaty negotiations between Spain and the United Kingdom are scheduled. HMRC’s current list of inheritance tax double taxation conventions does not include Spain. British nationals with assets in Spain should treat double taxation exposure as a structural planning problem — not an exceptional edge case.Source: HM Revenue & Customs, Inheritance Tax Double Taxation Conventions, April 2026.

A partial unilateral credit mechanism does exist in Spain: where an heir has paid inheritance tax abroad on the same assets, a deduction may be sought in the Spanish ISD declaration for the amount already paid. This credit is not automatic — it must be correctly documented and claimed at the time of filing, with supporting evidence from the foreign tax authority.

Understanding your position under the applicable Spanish tax regime — particularly if you divide your time between Spain and the United Kingdom — is essential before any cross-border estate matter arises.

A Real-World Example: How an International Inheritance Unfolds

Legal concepts become clearer when seen through a real case. The following example — drawn from the firm’s own practice — illustrates the complexity that international heirs routinely face, and how specialist legal coordination makes the difference between a smooth settlement and a prolonged, costly dispute.

This case illustrates a consistent pattern in international estate work: complexity is rarely exceptional — it is the norm when cross-border assets, multiple heirs and different national legal systems converge. The families who navigate these situations most successfully are those who engage specialised legal representation early, before the six-month clock has started running against them.

Estate Planning for International Inheritances in Spain

Proper estate planning is the most effective means of controlling both the legal and fiscal outcome of an international inheritance. Acting before death — rather than after — creates options that are simply not available once a succession has been formally opened.

Why Every Foreign Asset Owner in Spain Should Have a Spanish Will

A Spanish will, executed before a Spanish notary and registered with the Registro General de Actos de Última Voluntad, provides:

• Clear designation of heirs and specific legacies for Spanish-sited assets.
• An express choice of the law of your nationality, where advantageous under EU Regulation 650/2012.
• Avoidance of costly intestate succession proceedings before Spanish courts.
• A simplified probate process, reducing the administrative burden on heirs at an already difficult time.

Where a foreign national dies without a valid Spanish will, intestate succession proceedings are governed by the Spanish Civil Code (Real Decreto de 24 de julio de 1889) or the applicable foreign national law — a determination that itself requires separate legal analysis. Intestate proceedings substantially increase the time, cost and complexity of settling a Spanish estate and can delay asset access by heirs for months or years.Source: Código Civil Español, BOE-A-1889-4763.

Single International Will or Separate National Wills?

Approach	Advantages	Risks and Limitations
Single international will	One document covering all assets; consistent expression of wishes across borders	Must be compatible with every relevant jurisdiction; forced heirship conflicts possible; translation and apostille requirements
Separate national wills	Each will precisely meets local requirements; simpler local probate in each country	Wills must not contradict each other; requires coordination between advisers in each jurisdiction; risk of one superseding the other if not carefully drafted

Where the estate spans Spain and the United Kingdom, coordinating a Spanish will with a UK will — prepared with the assistance of specialists in both jurisdictions — is generally the most legally secure approach.

Your Three Options as a Foreign Heir

Once a Spanish succession is formally opened, you face three legally defined choices under the Spanish Civil Code.

• Accept outright (aceptación pura y simple): You acquire all assets and assume all debts, including any liabilities not previously identified. This carries the greatest personal risk where the estate’s debt position is unclear.
• Accept under benefit of inventory (aceptación a beneficio de inventario): Your personal liability is capped at the value of the inherited assets. This must be formally exercised and is strongly advisable where the estate may include significant liabilities.
• Renounce the inheritance (repudiación): You formally disclaim the inheritance before a Spanish notary. Renunciation is generally irrevocable once completed and can itself trigger ISD consequences for the heirs who ultimately receive the estate.

Where multiple heirs cannot agree on distribution, an executor named in the will — or a court-appointed administrator — may be required to intervene. The firm’s direct experience in international succession cases in the Valencian Community, including cross-border asset sales, repatriation of proceeds and dual-jurisdiction tax filings, provides clients with an end-to-end service that avoids the fragmentation that arises from dealing with multiple uncoordinated advisers.

Practical Checklist: Accepting a Spanish Inheritance as a Non-Resident

• Obtain the death certificate and have it apostilled under the Hague Convention of 5 October 1961 if required for use outside the country of issue.
• Request the Certificado de Últimas Voluntades from the Spanish Ministry of Justice to confirm whether a will is registered in Spain.
• Where a will exists, obtain a notarised copy from the notary holding the original protocol.
• Identify and value all Spanish assets: real estate at fiscal value, bank and investment accounts, vehicles, business interests, intellectual property rights.
• Obtain a Número de Identificación de Extranjero (NIE) for each foreign-national heir — mandatory for the ISD declaration and any property registration. See our guide on obtaining an NIE in Spain.
• Grant a notarised power of attorney to your Spanish legal representative, with apostille if executed outside Spain.
• File the ISD declaration using Modelo 650 (inheritance) or Modelo 660 (informational) within six months of the date of death.
• File the Plusvalía municipal declaration with the relevant town council for any inherited real property.
• Register real estate transfers with the Registro de la Propiedad in the relevant land registry district.
• Where applicable, file Modelo 720 if you become a Spanish tax resident holding foreign assets exceeding €50,000 in any of the three categories. See our Modelo 720 guide.
• Assess capital gains tax implications separately if any inherited property is subsequently sold — these are distinct from and additional to ISD.

Spain Inheritance Law and Expert Legal Advice in 2026

International inheritances in Spain sit at the intersection of EU succession law, Spanish national tax legislation, autonomous community fiscal rules and — for British nationals — the post-Brexit private international law landscape. Uninformed decisions in this context carry real financial consequences.

The practical recommendations for anyone with cross-border succession exposure in 2026 are clear.

• Draft a Spanish will if you own assets in Spain — this is the single most effective action you can take to protect your heirs.
• Seek specialist inheritance law advice in Spain before a succession event occurs, not after the six-month deadline has started running.
• Verify your domicile and residency position under both Spanish and UK law if you divide your time between the two countries.
• Assess the interaction between ISD and UK IHT with a specialist who understands both systems.
• Engage a firm with established relationships with the AEAT, Spanish notaries and the Registro de la Propiedad — coordination across these institutions is essential for a timely and clean settlement.

Our tax law and accounting team works in direct coordination with our inheritance law specialists to ensure that every aspect of your estate — from the initial asset inventory to the final repatriation of funds — is handled correctly, efficiently and in full compliance with Spanish legal obligations.

Frequently Asked Questions: Inheritance Tax in Spain for Non-Residents

Do non-residents have to pay inheritance tax in Spain?

Yes. A non-resident heir who inherits assets physically located in Spain must declare and pay Spanish ISD on those assets, regardless of where they live. Following ECJ Case C-127/12, non-residents are entitled to apply the regional rules of the autonomous community where the assets are located — the same rules available to resident heirs — rather than the less favourable national scale.

What is the deadline for declaring an inheritance in Spain?

The standard deadline is six calendar months from the date of death. An extension of a further six months may be requested from the relevant autonomous community tax authority before the initial period expires, bringing the maximum deadline to twelve months. Late submission triggers late-payment interest and surcharges under Article 27 of the Ley General Tributaria.

Is there an inheritance tax treaty between Spain and the United Kingdom?

No. As of 2026, Spain and the United Kingdom have no bilateral treaty covering inheritance or gift tax. British nationals may therefore face taxation in both jurisdictions on the same inherited assets, depending on the deceased’s domicile status and the location of the assets. Unilateral credit mechanisms exist in Spain but must be actively claimed with proper documentary evidence at the time of filing.

Can I choose which country’s succession law governs my Spanish estate?

Yes, within the framework of EU Regulation 650/2012. You may state in your will that the law of your nationality — rather than the law of your habitual residence — governs your succession. A British national habitually resident in Spain could elect English law to govern the distribution of their estate. This election must be expressly stated in a valid will. Choosing a foreign succession law does not remove the obligation to pay Spanish ISD on assets located in Spain.

What inheritance tax reductions apply in the Valencian Community?

As of 2026, direct-line relatives in Group I and II — children, grandchildren, parents, grandparents and spouses — benefit from a 50% reduction on the ISD quota in the Valencian Community. Individual tax-free allowances include approximately €100,000 per child and approximately €156,000 for surviving spouses, subject to age and disability adjustments. These figures should be verified at the time of declaration as the regime has been subject to ongoing reform.

Do I need an NIE to accept an inheritance in Spain?

Yes. Each foreign-national heir must hold a Número de Identificación de Extranjero (NIE) to submit the ISD declaration, appear before a Spanish notary and complete any property registration. An NIE can be obtained from the Spanish consulate in your country of residence or, in certain circumstances, from the relevant Policía Nacional office in Spain.

What is Modelo 650 and when must it be filed?

Modelo 650 is the official Spanish tax form for declaring and paying ISD when assets are acquired by inheritance. It must be filed with the competent autonomous community tax authority — in the Valencian Community, the Conselleria d’Hisenda i Model Econòmic — within six months of the date of death (extendable to twelve months on request). Modelo 660 is used for informational declarations where no ISD is payable but a formal filing remains legally required.

What is the Certificado de Últimas Voluntades and why does it matter?

The Certificado de Últimas Voluntades is a certificate issued by the Spanish Ministry of Justice confirming whether the deceased left a registered will in Spain and, if so, which notary holds the original protocol. It is an essential first step in any Spanish succession and must be obtained before the probate process can proceed. It requires a certified copy of the death certificate and can be requested online or by post.

What happens if multiple heirs cannot agree on distributing the estate?

Where heirs cannot reach agreement, the executor named in the will may intervene. Where no executor was appointed or the dispute cannot be resolved privately, judicial partition proceedings (juicio de división de herencia) may be initiated before the competent Spanish court. Spanish courts can order the sale of indivisible assets — including real property — where physical division is not possible. Early legal intervention substantially reduces cost and duration.

Can I renounce a Spanish inheritance?

Yes. Renunciation must be executed by a public deed (escritura pública) before a Spanish notary and is generally irrevocable once completed. There are two forms: renuncia abdicativa (outright disclaimer, with the disclaimed share passing to remaining heirs by operation of law) and renuncia traslativa (renunciation in favour of a specific heir, which itself triggers ISD as a gift). Renunciation decisions should never be made without legal advice — the tax consequences can be significant.
