Key Takeaways
- In Spain, beneficiaries pay the tax — not the estate. Each heir files and pays separately, unlike the UK where inheritance tax is settled before any distribution to heirs.
- Regional rules dominate — Andalusia offers near-zero ISD for Group I and II heirs. Spouses and children inheriting in Andalusia typically pay little or no Spanish inheritance tax due to regional bonifications of up to 99%.
- The UK-Spain double-taxation treaty prevents being taxed twice. Any ISD paid in Spain on Spanish assets can be offset against the UK inheritance tax liability for the same assets.
- Tax must be filed within 6 months of death. Extensions can be requested but must be applied for within the first 5 months — missing the deadline triggers surcharges of 5-20% plus interest.

Spanish Inheritance Tax for UK Expats: A Simple Guide
Navigating Spanish Inheritance Tax (known as Impuesto de Sucesiones y Donaciones or ISD) can seem daunting. The rules are complex and vary by region, but for most UK expats on the Costa del Sol, understanding the basics can provide clarity and help you plan ahead. This guide simplifies the key concepts.
If you are a Spanish tax resident, your worldwide assets may be subject to Spanish ISD rules. This is one of several tax obligations that catches UK expats off guard, alongside Modelo 720 foreign asset reporting and annual income tax declarations.
Who Pays the Tax?
Unlike in the UK where inheritance tax is paid by the deceased’s estate, in Spain, the tax is paid by each individual beneficiary. The amount of tax each person pays depends on several factors:
- The value of the assets they inherit.
- Their relationship to the deceased (spouses, children, and direct ascendants pay less).
- Their pre-existing wealth.
- The autonomous community (region) where the assets are located.
This is a fundamentally different approach from the UK system. If you own property on the Costa del Sol, each of your heirs will file separately based on what they receive, not based on the total estate value.
State vs. Regional Rules
Spain has a set of state rules for inheritance tax, but each of its 17 autonomous communities has the power to apply its own, often more generous, reductions and allowances. For example, regions like Andalusia and Madrid offer significant tax relief for close relatives (Group I and II beneficiaries), meaning many spouses and children pay very little or no inheritance tax.
Crucially, the applicable rules depend on where the deceased lived or where the property is located. It is essential to get localized advice. For property on the Costa del Sol, Andalusian rules apply, and these are among the most generous in Spain for direct family members.
Tax-Free Allowances
Each beneficiary is entitled to a tax-free allowance based on their relationship to the deceased:
- Group I: Children (including adopted) under 21. Highest allowance.
- Group II: Children over 21, spouses, parents, and grandparents. Significant allowance.
- Group III: Siblings, cousins, aunts, uncles. Smaller allowance.
- Group IV: Unrelated individuals. No allowance.
In Andalusia specifically, Group I and II beneficiaries can benefit from bonifications of up to 99%, effectively reducing the tax to near zero for most direct family inheritances. This is a significant advantage compared to other Spanish regions and compared to the UK system.
The Double-Taxation Treaty
The UK and Spain have a double-taxation treaty to prevent assets from being taxed in both countries. In practice, any inheritance tax paid in Spain on Spanish assets can typically be offset against the UK inheritance tax bill for the same assets.
This works in both directions. If UK IHT is paid on assets that are also subject to Spanish ISD, the tax paid in one country can be credited against the liability in the other. However, the mechanics are complex and the two systems calculate tax differently (estate-level in the UK vs. beneficiary-level in Spain), so professional advice from an adviser familiar with both jurisdictions is essential.
Assets held in the UK by a Spanish resident may also need to be declared on Modelo 720 during the owner’s lifetime. The reporting trail created by Modelo 720 can simplify inheritance proceedings later, since the asset base is already documented.
Filing Deadlines and Process
Spanish inheritance tax must be filed within 6 months of the date of death. An extension of 6 additional months can be requested, but the request must be submitted within the first 5 months. Missing the initial deadline without an extension triggers surcharges:
- 1-3 months late: 5% surcharge
- 3-6 months late: 10% surcharge
- 6-12 months late: 15% surcharge
- Over 12 months late: 20% surcharge plus interest
The filing is done by each beneficiary separately at the regional tax office. On the Costa del Sol, a gestoría or specialist lawyer handles this process. If you are managing the estate of someone who passed away in Spain, an English-speaking gestoría on the Costa del Sol can navigate both the Spanish paperwork and coordinate with UK solicitors.
Do UK Assets Get Taxed in Spain?
If the deceased was a Spanish tax resident at the time of death, Spain can tax their worldwide estate, including UK assets. If the deceased was a UK resident who owned property in Spain, only the Spanish assets fall under Spanish ISD. The beneficiaries’ residency also matters: a Spanish-resident beneficiary may owe Spanish ISD on worldwide inherited assets regardless of where the deceased lived.
For UK expats on the Costa del Sol, this typically means both Spanish and UK assets are in scope. Proper estate planning, including a Spanish will for Spanish property, can significantly simplify the process and reduce delays for your heirs.
Practical Steps for UK Expats
- Make a Spanish will covering your Spanish assets. A UK will can cover UK assets separately.
- Understand which Andalusian bonifications apply to your family structure.
- Keep your Modelo 720 filings current so your asset base is already documented.
- Discuss the double-taxation implications with an adviser who understands both UK IHT and Spanish ISD.
- Review your arrangements periodically, especially after buying or selling property or after changes in family circumstances.
Once the tax implications are clear, the next step is the legal process of transferring the assets. Learn more in our guide to the probate process in Spain.

Frequently Asked Questions
Does the UK-Spain double-taxation treaty prevent me from being taxed twice on the same inheritance?
Yes, in principle. The treaty allows tax paid in one country to be credited against the liability in the other. If Spanish ISD is paid on Spanish assets, that amount can typically be offset against any UK IHT due on those same assets. However, because the UK taxes at the estate level and Spain taxes at the beneficiary level, the calculations do not map perfectly. You need an adviser familiar with both systems to ensure the credits are applied correctly and that no tax is paid twice.
What are the Andalusian inheritance tax allowances for close relatives?
Andalusia offers bonifications of up to 99% for Group I (children under 21) and Group II (children over 21, spouses, parents, grandparents) beneficiaries. In practice, this means most direct family inheritances on the Costa del Sol attract little or no Spanish inheritance tax. Group III (siblings, extended family) and Group IV (unrelated persons) do not receive these bonifications and face significantly higher effective rates.
Do UK assets get taxed in Spain if I am a Spanish resident?
If you are a Spanish tax resident at the time of death, Spain can tax your worldwide estate, including UK bank accounts, investments, and property. Your beneficiaries who are also Spanish residents may owe Spanish ISD on everything they inherit from you, regardless of where the assets are located. The double-taxation treaty provides relief against being taxed twice, but your heirs will still need to file in Spain and claim the appropriate credits.
What is the time limit for filing Spanish inheritance tax?
The standard deadline is 6 months from the date of death. An extension of 6 additional months can be requested, but the extension request itself must be filed within the first 5 months. After the deadline passes without filing, surcharges of 5-20% apply depending on how late the filing is, plus interest. Given the complexity of cross-border estates, starting the process as soon as possible is strongly recommended.
Should I have a separate Spanish will for my Spanish assets?
Yes. Having a Spanish will that covers your Spanish assets (property, bank accounts, vehicles) significantly speeds up the inheritance process for your heirs. Without one, your UK will must be translated, apostilled, and recognised by Spanish authorities, which adds months and considerable cost. The Spanish will should explicitly state that it covers only Spanish assets, so it does not inadvertently revoke your UK will. A Spanish lawyer can draft one for €200-400.
How does Spanish inheritance tax interact with Modelo 720?
Modelo 720 is a lifetime reporting obligation for foreign assets held by Spanish tax residents. While it is not directly part of the inheritance tax process, the documentation trail it creates makes estate administration easier. If the deceased filed Modelo 720 regularly, the heirs and their advisers already have a documented record of foreign assets, valuations, and account details. Conversely, if Modelo 720 was never filed, the inheritance process may surface unreported assets that create additional compliance issues.
