Spanish Inheritance Tax for British Property Owners: What You and Your Family Will Owe
A British buyer asked me something sharp at the end of a property viewing in Estepona last year: “If I die owning this apartment, what happens to my kids?”
It is the question most people ask about three months after they have already signed. The good news, for families buying on the Costa del Sol, is that the inheritance tax picture in 2026 is much better than most people expect. The honest answer: it depends on who inherits, what the property is worth, and whether you have done a few straightforward things beforehand.
How Spanish Inheritance Tax Works
Spain charges Impuesto sobre Sucesiones y Donaciones (ISD) on inherited assets located in Spain. Critically, the tax falls on the heirs, not on the estate itself. Each heir is taxed individually on their share of what they receive.
At state level, the rates run from 7.65% on the first €7,993 up to 34% on amounts above €797,555. An additional multiplier of between 1.0 and 2.4 is then applied on top, based on how wealthy the heir already is. In practice, for most British families inheriting a Costa del Sol apartment, those headline rates do not apply — because of what Andalusia does next.
The Andalusian Advantage
Spain’s inheritance tax is devolved. Each of the country’s 17 regions sets its own rules on top of the state framework, and Andalusia (the region covering Marbella, Estepona, Sotogrande, Benahavís, and the entire Costa del Sol) offers one of the most generous regimes in the country.
Since April 2019, Andalusia applies a 99% bonificación (reduction) on ISD for heirs in Group I and Group II:
- Group I: Children under 21
- Group II: Spouses, children 21 or over, parents, grandparents, grandchildren
A surviving spouse or adult child inheriting a €500,000 apartment pays, at most, 1% of the calculated tax liability. On a typical Costa del Sol property, that works out to a few hundred euros rather than tens of thousands.
A worked example
A parent dies leaving a €500,000 apartment to two adult children. Each child inherits €250,000.
Without any reduction, the state-level ISD on a €250,000 share would be roughly €28,000 per heir. With Andalusia’s 99% bonificación, each child pays approximately €280.
For a spouse inheriting from a partner: the same 99% reduction applies. A surviving husband or wife inheriting a €700,000 home pays around €500 in ISD in total.
The Post-Brexit Question
Before 2015, UK residents were treated as non-EU heirs under Spanish law and lost access to regional reductions, paying harsher state-level rates. That changed after a European Court of Justice ruling forced Spain to extend regional rules to EU citizens.
Post-Brexit, UK citizens are technically third-country nationals. However, Spain subsequently extended the right to use regional rules to all heirs of Spanish-situated property, regardless of the heir’s country of residence. This was confirmed through Royal Decree-Law 8/2015 and its subsequent extensions, and Andalusia applies it in practice.
UK heirs inheriting Andalusian property can use Andalusia’s 99% reduction. You do not lose the bonificación because you live in Manchester or Edinburgh. The law can change, and you should get written confirmation from your Spanish tax adviser at the time of the inheritance.
The 6-Month Rule
Spanish inheritance tax must be declared within six months of the date of death. Miss the deadline and you face penalties of 5% to 20% of the amount due, plus daily interest.
You can apply for a six-month extension, but you must do so before the original deadline expires. Most Spanish solicitors and gestores file the extension as a matter of course when acting for non-resident heirs. Do not assume it happens automatically: if you are using the same solicitor who handled the purchase, confirm they will manage the succession process or that you have engaged someone who will.
The declaration is filed on Form 650 (non-residents) or Form 660 (residents). For UK families, this is almost always Form 650, filed with the relevant Delegación de la Agencia Tributaria in the province where the property is located.
Do Not Forget Plusvalía Municipal
On top of ISD, the heir owes Plusvalía Municipal: the local land value increment tax charged by the town hall (ayuntamiento). It is based on the increase in the official cadastral value of the land since the property was last transferred.
The amount varies by municipality and by how long the owner held the property. On a Costa del Sol property held for 10 to 15 years, you might expect a bill of €2,000 to €8,000. It is a real cost and it is consistently overlooked by families who have only been quoted ISD.
One important note: if the property has not increased in value since purchase, you can now contest the plusvalía calculation. A 2021 Constitutional Court ruling struck down the old formula as unconstitutional where no real gain had been made. A Spanish solicitor can advise whether this applies to your situation.
What About Group III and Group IV Heirs?
The 99% reduction applies only to direct family (Groups I and II). If you leave Spanish property to a sibling, niece, nephew, or anyone outside the immediate family tree, the position is considerably less favourable:
- Group III (siblings, aunts, uncles, nieces, nephews): partial or no reduction, effective rates typically 15-25%
- Group IV (more distant relatives or unrelated beneficiaries): no reduction, top multipliers apply, effective rates can reach 34-40% or higher on large estates
If you intend to leave your Spanish property to anyone outside your direct family, get proper estate planning advice now. The cost of planning is a fraction of the tax bill that can arise without it.
The Spanish Will: One Document That Changes Everything
The single most practical thing a British property owner in Spain can do is make a Spanish will covering Spanish assets specifically. This is separate from your UK will.
Without a Spanish will:
- Your UK will must be translated into Spanish, apostilled, and processed through Spanish courts
- This adds months and significant cost to the process at exactly the time your family can least afford delays
- Spanish probate applies to your property by default, on Spain’s timetable
With a Spanish will (testamento):
- Drawn up before a Spanish notario, it takes about an hour and costs roughly €100 to €200
- It is registered with Spain’s Central Registry of Last Wills (Registro General de Actos de Última Voluntad), so your heirs can locate it quickly
- You can specify that British inheritance law governs succession to your Spanish assets (EU Succession Regulation 650/2012 permits this choice for UK nationals, though your solicitor should advise on which is more beneficial in your case)
Every British buyer should make a Spanish will before or shortly after completing their purchase. At €100–€200, it is the cheapest protection in the entire transaction.

How to Reduce Your Exposure Further
Beyond making a will, a few other approaches are worth knowing about:
Joint ownership: If you buy with a spouse and hold the property as co-owners, only the deceased’s share passes through succession. The surviving spouse already owns their half.
Life insurance: A Spanish life policy paid to the heirs can be structured to cover any ISD and plusvalía liability, avoiding a forced sale of the property to cover the tax bill.
Gifting during your lifetime: Spain taxes lifetime gifts under the same ISD framework. In Andalusia, the 99% bonificación has applied to lifetime gifts to direct family since 2022. Some families use partial ownership transfers while both parties are alive to reduce the estate that passes on death. Specialist tax and legal advice is essential before taking this route.
Practical Steps to Take Now
- Make a Spanish will at a notario in Spain (cost: around €150 in most areas)
- Confirm your property is correctly registered at the Registro de la Propiedad (land registry)
- Brief your family on where documents are held: the escritura (title deed), your NIE numbers, and the contact details of your Spanish solicitor or gestor
- If passing to anyone outside direct family, instruct an inheritance tax specialist before the property changes hands
If you still need to obtain your NIE or are navigating the Spanish bureaucracy for the first time, our NIE number guide for UK buyers explains the full process step by step.
Always verify current rates and regional rules with a qualified Spanish tax adviser before relying on any figures. Rates, allowances, and regional bonificaciones can and do change.
