Spanish inheritance tax reaches UK owners because Spain taxes assets by where they sit, not by where the owner lived. If you own property in Spain, that property falls within the Spanish tax net even if you have never been resident there, and the person who inherits it is the one who pays.
How does Spanish inheritance tax work for UK owners?
Spanish inheritance tax, called Impuesto sobre Sucesiones y Donaciones (ISD), is charged on the Spanish-located asset regardless of where the deceased lived. Unlike UK inheritance tax, which the estate pays, Spanish tax is paid by each beneficiary on what they personally receive, and it must be settled within six months of the death.
Two features surprise most UK owners. First, being non-resident in Spain gives no exemption: the villa or apartment is Spanish-situated, so Spanish tax applies. Second, the tax is calculated per heir, so what your children pay depends on their relationship to you, their existing wealth, and above all the region where the property lies. Our guide to international and cross-border estate planning covers how this sits alongside UK rules.
How much is Spanish inheritance tax?
The Spanish state scale runs from 7.65% on the first slice up to 34% on the largest inheritances, applied to each beneficiary's share after a personal allowance. That allowance ranges from €7,993 to €47,859 depending on how closely the heir is related, and a separate reduction of up to 95% can apply to a main home. Regional rules then often cut the final bill sharply.
| Beneficiary group | Who is in it | State personal allowance |
|---|---|---|
| Group I | Children and grandchildren under 21 | €15,957, plus €3,990 for each year under 21 (capped at €47,859) |
| Group II | Children and grandchildren 21 or over, spouses, parents, grandparents | €15,957 |
| Group III | Siblings, aunts, uncles, nieces, nephews, in-laws | €7,993 |
| Group IV | Cousins and unrelated heirs (including unmarried partners) | No state allowance |

A multiplier then adjusts the tax for distant or wealthier heirs, so a niece or an unmarried partner can pay several times what a child pays on the same amount. This is why an unmarried partner or a friend inheriting a Spanish property often faces the heaviest bill.
Why does the Spanish region matter so much?
Each of Spain's 17 autonomous communities can override the state allowances, and the differences are large. For close family (Groups I and II), several regions reduce the tax by up to 99%, while others charge close to the full state amount. Where you buy in Spain can matter more to your heirs than the value of the property itself.
| Region | Typical treatment for close family (Groups I and II) |
|---|---|
| Andalucía | Allowance of up to €1,000,000 per beneficiary, then a 99% reduction on tax above it |
| Madrid | 99% reduction on the tax due |
| Valencian Community | 99% bonus for close family under current 2026 rules |
| Catalonia | More modest reductions; effective rates rise with the size of the inheritance |
Source: regional (autonomous community) ISD rules, as at August 2026, subject to change. Regional reliefs change often and each has its own conditions.
Regional relief usually depends on the heir's relationship and sometimes on keeping the property for a number of years. It does not remove UK inheritance tax, which is the trap covered next.
Will your heirs be taxed twice, in Spain and the UK?
They can be, because there is no UK-Spain treaty for inheritance tax. The double taxation agreement between the two countries covers income tax and capital gains tax only, not death taxes. So Spain can charge ISD on the Spanish property, and the UK can charge inheritance tax on the same property as part of your worldwide estate.
UK inheritance tax applies to your worldwide estate if you are a long-term UK resident, meaning UK resident for at least 10 of the previous 20 tax years, the residence test that replaced domicile on 6 April 2025 (gov.uk, Inheritance Tax if you are a long-term UK resident, as at August 2026, subject to change). Above the £325,000 nil-rate band, and a residence nil-rate band of up to £175,000 where a home passes to direct descendants, the rate is 40%, with the bands frozen until 5 April 2031 (gov.uk, Inheritance Tax rates and allowances, as at August 2026, subject to change).
The relief that stops full double taxation is unilateral relief. The UK credits the Spanish inheritance tax paid on the Spanish property against the UK inheritance tax due on that same property, giving credit for the lower of the two charges (gov.uk, Inheritance Tax double taxation relief, as at August 2026, subject to change). In practice this means your heirs pay roughly the higher of the two taxes on that property, not the sum of both. Our inheritance tax overview explains how the UK bands work in full.
Worked example: how the two taxes net out
This shows how unilateral relief works on one Spanish property, so the arithmetic that competitors skip is clear. Take a UK owner who is a long-term UK resident, leaving a €300,000 villa (about £255,000) to one adult child. Assume the UK nil-rate bands are used by other assets, so UK inheritance tax on the villa is 40%, roughly £102,000. The figures are illustrative and rounded; exchange rates and reliefs vary.
| Scenario | Spanish ISD paid | UK IHT after credit | Total on the villa |
|---|---|---|---|
| Villa in Andalucía, to a child (99% relief) | about £200 | £102,000 less £200 = £101,800 | about £102,000 |
| Region and heir with real Spanish tax (say £45,000) | £45,000 | £102,000 less £45,000 = £57,000 | £102,000 |
| Spanish tax higher than UK (say £120,000) | £120,000 | £102,000 less £102,000 = £0 | £120,000 |
Illustrative only. Based on gov.uk unilateral relief rules, as at August 2026, subject to change. Assumes an exchange rate near £1 to €1.17.
The pattern is the same in every row: the credit is the lower of the two taxes, so the family ends up paying the higher of the Spanish and UK charges on that property. Choosing a generous Spanish region does not save UK inheritance tax, because the UK charge simply fills the gap. Real savings usually come from the UK side of the plan, which is where inheritance tax planning strategies matter most.
Does a UK will cover your Spanish property, and what should you do?
A UK will alone is rarely enough for a Spanish property. Spanish succession law can apply forced heirship, reserving a fixed share for children, and Spanish authorities usually want documents in a form their system recognises. Handled badly, this delays the transfer and adds cost while the six-month tax clock runs.
- Make a Spanish will covering only your Spanish assets, drafted so it does not revoke your English will, and keep the two consistent. See our guide on how to write a will for the UK side.
- Consider a Brussels IV election. As a British national you can state in your will that the law of your nationality governs succession, which can set aside Spanish forced heirship, though it does not change the tax.
- Make sure each heir has a Spanish tax number (NIE), which they will need to file and pay ISD.
- File and pay Spanish inheritance tax within six months of the death; an extension can be requested within the first five months, and late payment adds surcharges and interest.
- Budget for the plusvalía municipal, a separate local tax on the increase in land value, and keep evidence of the Spanish tax paid so UK unilateral relief can be claimed.
Because the two systems interact, a plan that looks tidy in one country can fail in the other. Reviewing both sides together is the point of good estate planning for cross-border families.
Frequently asked questions
These are the questions we are asked most often by UK owners about Spanish property and UK inheritance tax. Each answer describes general rules under the law of England and Wales and current Spanish practice, not advice on your own estate or your particular situation.
Is there a double tax treaty between the UK and Spain for inheritance tax?
No. The UK-Spain double taxation agreement covers income tax and capital gains tax, not inheritance or death taxes. A Spanish property can therefore fall within both Spanish inheritance tax and UK inheritance tax. UK unilateral relief usually credits the Spanish tax paid against the UK bill on the same asset, giving relief for the lower of the two charges (gov.uk, as at August 2026, subject to change).
Who pays Spanish inheritance tax, the estate or the beneficiary?
The beneficiary pays. Spanish inheritance tax is charged on each person who inherits, based on what they receive, their relationship to the deceased, and the region where the asset sits. This differs from UK inheritance tax, which the estate settles before assets are distributed. Spanish tax must normally be paid within six months of the death.
How much is Spanish inheritance tax for a UK owner's family?
Spanish state rates run from 7.65% to 34% of each heir's share after a personal allowance of €7,993 to €47,859, with a multiplier for distant or wealthier heirs. Regional rules can cut this sharply: for close family, Andalucía, Madrid and the Valencian Community can reduce the tax by up to 99%. The final figure depends heavily on the region and the heir (as at August 2026, subject to change).
Does a UK will cover property in Spain?
Usually not on its own. Spanish succession law can apply forced heirship and Spanish authorities prefer documents their system recognises, so most owners make a separate Spanish will for their Spanish assets, drafted so it does not revoke the English will. A Brussels IV election can let a British national apply the law of their nationality to succession, though it does not change the tax due.
Can you avoid your heirs being taxed twice on a Spanish property?
Full double taxation is usually avoided by unilateral relief, not by choosing a low-tax Spanish region. The UK credits Spanish inheritance tax paid against UK inheritance tax on the same property, so the family effectively pays the higher of the two charges rather than both. Keeping evidence of the Spanish tax paid is what makes the UK relief claim work (gov.uk, as at August 2026, subject to change).
