Inheritance Tax for Non-Residents in Spain: What Expat Heirs Need to Know

In brief: If you inherit assets located in Spain but live outside Spain, you are liable for Spanish inheritance tax — even if you never set foot in the country during the succession process. The rules changed significantly after a 2014 European Court of Justice ruling, and non-resident heirs now have access to the same regional reductions as Spanish residents. This guide explains how the tax works, what it costs, and how to prepare.

Who Pays Inheritance Tax in Spain

Spain's Impuesto sobre Sucesiones y Donaciones (ISD) applies when assets located in Spain are inherited. The liability falls on the heir, not the estate — and it applies regardless of where the heir lives.

This means:

A British adult child living in London who inherits a Spanish apartment from a parent who lived in Valencia owes Spanish inheritance tax on that property
A French national living in Paris who inherits Spanish bank account funds from a sibling resident in Barcelona is liable for Spanish ISD
A Belgian resident who receives a bequest from a Spanish estate must pay Spanish tax before the assets can be transferred

The obligation does not disappear because you are not a Spanish resident. What changes is how the tax is calculated — and this is where the post-2014 rules matter enormously.

The ECJ Ruling That Changed Everything

Before 2014, non-resident heirs were systematically disadvantaged. Spanish inheritance tax is administered by the Comunidades Autónomas (regional governments), and most regions offer significant reductions — sometimes up to 99% — for direct heirs. But these reductions were only available to residents of that region.

A non-resident heir inherited the same apartment in Andalucía but paid the full national rate, with no access to regional bonifications. The effective tax rate for non-residents was often 5–10 times higher than for residents inheriting identical assets.

In September 2014, the European Court of Justice ruled (Case C-127/12) that Spain's differential treatment of EU/EEA residents was incompatible with EU freedom of capital rules. The Spanish government subsequently amended the ISD law (Law 26/2014).

The result: Non-resident heirs who are EU or EEA nationals can now apply the regional rules of the region where the assets are located (for real property) or where the deceased was resident (for other assets). The discrimination has been formally removed.

Important limitation: This ruling and the resulting reform apply to EU and EEA nationals. Non-EEA nationals (including, post-Brexit, British citizens) are in a more complex position — though subsequent administrative guidance and tax authority practice has extended similar treatment in many cases. British expats and their heirs should take specific legal advice on their position.

How the Tax Is Calculated

The national framework

Spanish ISD is calculated on the net value of assets inherited (assets minus debts and deductible expenses). The national rate schedule is:

Net taxable base	Marginal rate
Up to €7,993	7.65%
€7,993 – €31,956	10.20%
€31,956 – €79,881	15.30%
€79,881 – €239,389	21.25%
€239,389 – €398,778	25.50%
€398,778 – €797,555	29.75%
Over €797,555	34.00%

Multipliers based on relationship and existing wealth

The calculated tax is then multiplied based on: (a) the heir's relationship to the deceased, and (b) the heir's pre-existing wealth. Closer relatives with modest wealth pay the base rate. More distant relatives with significant existing assets can pay up to 2.4× the base rate.

Relationship groups:

Group I: Children and adopted children under 21
Group II: Children and adopted children over 21, spouses, parents
Group III: Brothers, sisters, uncles, aunts, nephews, nieces, in-laws
Group IV: Other relatives and unrelated persons

Regional reductions — why they matter

Regional bonifications are where the real tax variation occurs. Some examples:

Region	Reduction for Group II heirs	Effective rate
Madrid	99% reduction	~0.5–1%
Andalucía	99% reduction (since 2019)	~0.5–1%
Canarias	99.9% reduction	~0%
Cataluña	Partial reduction; scales with value	5–32%
Valencia	Reduction abolished 2017, partially reinstated	Varies
Murcia	99% reduction	~0.5–1%

For a Group II heir (adult child) inheriting a €300,000 apartment in Madrid, the effective tax after the regional 99% reduction is approximately €1,500–3,000. The same inheritance in Cataluña might cost €15,000–40,000 in tax.

As a non-resident EU/EEA heir, you apply the rules of the region where the real estate is located. Knowing where your inherited property is located — and what rules apply there — can have a significant financial impact.

What Non-Resident Heirs Actually Need to Do

1. File within 6 months of death

The deadline for declaring and paying Impuesto sobre Sucesiones is 6 months from the date of death. A 6-month extension can be requested within the first 5 months — but interest accrues on any outstanding amount during the extension period.

Missing the deadline triggers surcharges: 5% for up to 3 months late, 10% for 3–6 months, 15% for 6–12 months, and 20% plus interest after 12 months.

2. File in the right jurisdiction

For real property: file in the Comunidad Autónoma where the property is located. For other assets (bank accounts, investments) when the deceased was resident in Spain: file in the region of the deceased's residence. For non-resident deceased with assets in Spain: file with the central tax authority (Agencia Tributaria — Delegación Central) rather than a regional authority.

3. Obtain the necessary documents

Non-resident heirs typically need:

Original death certificate (with apostille if issued abroad, and official Spanish translation)
Certificate of last wills (Certificado de Últimas Voluntades) from the Spanish Registry of Wills — obtainable 15 business days after death registration
Certified copy of the will (if one exists in Spain) or declaration of heirs
NIE numbers (Número de Identificación de Extranjero) for all heirs — required to file tax and register property transfer
Valuation of Spanish assets (property: valor de referencia set by the Catastro; financial assets: market value at date of death)

4. Get a NIE number

Non-resident heirs who do not already have a Spanish NIE must obtain one to complete the succession process. This can be done at a Spanish consulate in your country of residence or directly in Spain. A Spanish gestor or solicitor can often obtain one on your behalf with a notarised power of attorney.

5. Register the property transfer

After paying ISD, real property must be transferred at the Land Registry (Registro de la Propiedad). This requires: the signed deed of inheritance (escritura de herencia) prepared by a Spanish notary, proof of ISD payment, and payment of municipal capital gains tax (plusvalía municipal) to the local authority.

Common Traps for Non-Resident Heirs

Assuming no tax is due because you live abroad. Incorrect. Tax liability follows the asset location, not the heir's residence.

Missing the 6-month deadline. The deadline runs from the date of death, not from when you were notified or when probate concluded in another country. Non-resident heirs dealing with a Spanish estate for the first time often lose weeks before they understand the process — and arrive at month 5 scrambling.

Not getting a NIE in time. The NIE application takes time, especially at consulates with high demand. Start immediately.

Undervaluing assets. The Spanish tax authority uses official reference values (valor de referencia) for property, which may differ from market value. Declaring a lower value than the reference value will trigger an automatic adjustment and potential penalty.

Assuming a foreign will is sufficient without Spanish legal process. A will valid in another country may be accepted in Spain, but it must be officially recognised (exequátur or EU Succession Certificate under EU Reg 650/2012). A Spanish notary handles this; it takes time and must be factored into the 6-month deadline.

How Prior Planning Reduces the Burden

The inheritance tax liability itself cannot generally be avoided through planning — the rate and reductions are fixed by law. What planning can do is ensure your heirs are not overwhelmed by a process they didn't know was coming.

For the person creating the estate:

Have a Spanish will: it simplifies the process, reduces notary fees, and removes the need for a declaration of heirs
Ensure your heirs know about all Spanish assets: bank accounts, property, and any other assets located in Spain
Consider whether joint ownership of Spanish property (adding an adult child to the title while alive) is appropriate — this reduces the value of the estate but has its own tax implications (Impuesto sobre Donaciones)
Life insurance with named beneficiaries can sometimes pass outside the succession estate, depending on policy structure

For heirs:

Start the process immediately on receiving notification of death — do not wait for probate to conclude in another country before addressing Spanish assets
Engage a Spanish gestor or solicitor with experience in non-resident inheritance from day one
Budget for ISD, plus notary fees (typically 0.5–1% of estate value), Land Registry fees, and legal costs

How Sucesio Supports the Process

Sucesio does not provide tax advice and does not replace a Spanish tax adviser, gestor, or notary. What Sucesio does is ensure that your heirs have the information they need to begin — and complete — the succession process without losing critical time.

With Sucesio, you can document:

The existence and location of all Spanish assets — property addresses, bank names, account types
Copies of key documents — NIE, will references, property deeds
Contact details for your Spanish notary, gestor, or legal adviser
Instructions for your heirs on what to do and in what order

This documentation, transmitted through Sucesio's secure vault at the time of your death, gives your heirs a map rather than a mystery. It does not reduce the tax — but it prevents the avoidable costs: missed deadlines, surcharges, delays, and errors caused by not knowing what exists.

Used alongside a Spanish will and professional legal advice, Sucesio ensures the administrative process is as straightforward as the legal framework allows.

Frequently Asked Questions

Do I have to pay Spanish inheritance tax if I live in the UK and inherit a Spanish property? Yes. Spanish ISD applies to assets located in Spain regardless of where the heir lives. Post-Brexit, British heirs are no longer EU/EEA nationals and their access to regional reductions may be more limited — though Spanish tax authority practice has generally extended similar treatment. Take specific legal advice on your position.

What is the deadline for paying Spanish inheritance tax? 6 months from the date of death, with a possible 6-month extension (subject to interest). Missing the deadline triggers surcharges of 5–20% plus interest.

Can I get a reduction as a non-resident EU heir? Yes. Following the 2014 ECJ ruling and subsequent Spanish law reform, EU and EEA nationals can apply the regional reductions of the region where the assets are located. In many regions (Madrid, Andalucía, Canarias), this reduces the effective rate to near zero for direct heirs.

Do I need to be in Spain to complete the inheritance process? Not necessarily. Much of the process — including filing ISD and obtaining documents — can be done remotely or through a Spanish gestor or solicitor acting under a notarised power of attorney.

What documents do I need to inherit Spanish property as a non-resident? A death certificate (apostilled and translated), the deceased's will or declaration of heirs, NIE numbers for all heirs, a valuation of the Spanish assets, and the Certificado de Últimas Voluntades. A Spanish notary prepares the inheritance deed; a gestor can manage the tax filing.

This article provides general information only. Spanish inheritance tax rules are complex and vary by region, nationality, and individual circumstances. Always consult a qualified Spanish tax adviser, gestor, or notary for advice specific to your situation. Sucesio complements — but does not replace — professional legal and tax advice.
