Inheriting a home on the Costa del Sol or a share of a family villa in Mallorca is rarely simple. Alongside the grief and the paperwork, two costs catch UK families out — and they are not the ones most people expect. The first is Spanish inheritance tax, which works very differently from the UK system. The second is currency — the often-overlooked cost of paying a euro tax bill and moving a euro inheritance back into pounds. Get either wrong and it can cost you tens of thousands.
This guide explains how Spanish inheritance tax works in 2026 for UK residents and non-residents, what you might pay, how to reduce it legitimately, and how to protect the money you eventually bring home.
What is Spanish inheritance tax?
Spanish inheritance tax — Impuesto sobre Sucesiones y Donaciones (ISD) — is a tax on what each person receivesfrom an estate or as a gift. This is the single most important difference from the UK:
| Spain (ISD) | UK (Inheritance Tax) |
| Paid by the beneficiary — each person who inherits, on their share. | Paid by the estate — before anything is distributed. |
| Tax depends on who you are and how closely related you were to the deceased. | Flat 40% above the tax-free threshold, regardless of relationship. |
| Applies to assets located in Spain (and to Spanish-resident beneficiaries’ worldwide inheritances). | Applies to the worldwide estate of someone UK-domiciled / long-term UK resident. |
| Due within 6 months of death. | Due within 6 months of the end of the month of death. |
So if you and two siblings inherit a Spanish property equally, you are each assessed separately on your one-third share — not on the whole estate.
Do UK residents and non-residents pay Spanish inheritance tax?
Yes. If you inherit an asset located in Spain — most commonly a property — Spanish inheritance tax for non residents applies, regardless of where you live. The good news for UK families is a landmark European Court of Justice ruling in 2015: non-residents must be treated the same as residents and can apply the rules of the Spanish autonomous region where the asset sits. Following Brexit, UK nationals continue to benefit from this equal treatment.
This matters enormously, because regional reliefs can turn a frightening tax bill into a negligible one — more on that below.
How much is Spanish inheritance tax? Rates and allowances
At national level, Spanish inheritance tax rates are progressive, rising from 7.65% to 34% on the largest inheritances. These are the approximate state marginal rates:
| Taxable amount (up to) | Marginal rate |
| €7,993 | 7.65% |
| €31,956 | 8.50% |
| €79,881 | 10.20% |
| €239,389 | 14.45% |
| €398,778 | 21.25% |
| €797,555 | 29.75% |
| Over €797,555 | 34.00% |
Note: a multiplier coefficient (from 1.0 to around 2.4) is then applied based on your relationship to the deceased and your existing wealth — and regional reductions are applied on top. The figures above are the starting point, not the final bill.
Before tax is calculated, each beneficiary gets a tax-free allowance based on their group:
| Group | Who it covers | State allowance |
| I | Children and descendants under 21 | €15,956.87 + €3,990.72 per year under 21 (max €47,858.59) |
| II | Children/descendants 21+, spouses, parents | €15,956.87 |
| III | Siblings, nieces/nephews, in-laws | €7,993.46 |
| IV | Cousins, distant relatives, unrelated | No allowance |
There is no spouse exemption like the UK’s. A surviving husband or wife is in Group II and is taxed on what they inherit — though regional relief often reduces this to almost nothing.
Why the Spanish region matters more than anything
Because each autonomous region sets its own reliefs, where the property sits can matter more than how much it is worth. Several regions — including Andalusia, Madrid, Murcia and Valencia — offer reductions of up to 99% for close family (Groups I and II). In Murcia, for example, spouses and children can benefit from a 99% reduction and a €100,000 per-beneficiary allowance.
The practical effect: two identical €500,000 inheritances can produce wildly different bills depending on region and relationship. This is also why a blanket online Spanish inheritance tax calculator can only ever give a rough guide — the regional layer is where the real numbers are decided.
Do you also pay UK inheritance tax on Spanish property?
Possibly — and this is where families get an unwelcome surprise. There is no double-taxation treaty between the UK and Spain for inheritance tax. So a Spanish property can fall into both systems:
- Spain taxes the Spanish-located asset (ISD), regardless of where the deceased lived.
- The UK taxes the worldwide estate — including the Spanish property — if the deceased was UK-domiciled or a long-term UK resident for inheritance tax purposes.
The relief that prevents you paying twice is the UK’s unilateral relief: Spanish inheritance tax paid on the Spanish asset can usually be credited against any UK inheritance tax due on that same asset. To claim it correctly you generally need to file in both countries, and a coordinated pair of wills (one for Spanish assets, one for UK assets) makes the whole process far smoother.
How to reduce or avoid Spanish inheritance tax (legitimately)
There is no magic way to make the tax disappear, but families who plan ahead pay far less than those who don’t. Common, legitimate steps include:
- Use the regional reliefs. Make sure the autonomous region’s reductions are claimed — this is the biggest lever by a distance.
- Hold a valid Spanish will. A Spanish will covering Spanish assets speeds up probate and helps elect the right succession law.
- Plan lifetime gifts carefully. Gifts are taxed under the same regime, so timing and structure matter.
- Mind the six-month deadline. Tax is due within six months of death; late payment brings surcharges and interest.
- Take cross-border advice early. Spanish and UK rules interact in complex ways; a specialist adviser usually saves far more than they cost.
The cost almost everyone forgets: currency
Here is the part the tax guides miss. A Spanish inheritance involves moving money across a currency border — usually twice — and the exchange rate can cost you more than the tax planning saved.
Paying the tax bill in euros
Spanish inheritance tax must be paid in euros, within six months. If you are a UK family holding pounds, you have to buy euros to settle it — and you are exposed to whatever the GBP/EUR rate happens to be on the day. Worse, you are working to a deadline, which removes your flexibility to wait for a better rate.
Bringing the inheritance home
If you later sell the inherited property, you will convert a large euro sum back into sterling. Consider a worked example:
You inherit and sell a villa, leaving €590,000 to bring home. At a GBP/EUR rate of 1.13 that is about £522,000. If the pound strengthens to 1.17 while the estate is settled, the same euros are worth about £504,000 — a difference of roughly £18,000 from a four-cent move. For many families that is more than the entire tax bill after regional relief.
This is exactly the risk Lucid is built to manage. A forward contract lets you fix today’s exchange rate for a transfer up to 12 months ahead — so you can lock in the rate to pay a Spanish tax bill, or to repatriate the proceeds, without gambling on the market. With competitive exchange rates and 1:1 specialist support, the saving on a six-figure transfer can be substantial.

Frequently asked questions
How much is Spanish inheritance tax?
National rates run from 7.65% to 34%, but the final figure depends on your relationship to the deceased, your existing wealth, and — crucially — the autonomous region, where reliefs of up to 99% are common for close family.
Do non-residents pay inheritance tax in Spain?
Yes, on Spanish-located assets. Since a 2015 EU court ruling, non-residents (including UK nationals) can apply the relevant region’s rules and reliefs, which usually reduces the bill significantly.
Do you pay UK inheritance tax on a Spanish property?
If the deceased was UK-domiciled or a long-term UK resident, the Spanish property forms part of their worldwide estate for UK inheritance tax. There is no UK–Spain inheritance tax treaty, but UK unilateral relief lets you offset Spanish tax paid against the UK bill on the same asset.
How can I avoid Spanish inheritance tax?
You cannot avoid it entirely, but claiming regional reliefs, holding a valid Spanish will, planning gifts carefully and taking early cross-border advice can reduce it dramatically.
When is Spanish inheritance tax due?
Within six months of the date of death. Extensions are sometimes possible, but late payment attracts surcharges and interest.
