Inheritance Tax in Spain for Expats — Region-by-Region Rules 2026

Spanish inheritance tax (Impuesto sobre Sucesiones y Donaciones) varies wildly by autonomous community — from a 99% reduction in Madrid to real five and six-figure bills in Cataluña and Asturias. Here is what British, American and international expats need to know to protect their families and their estate.

What Spanish Inheritance Tax Is — and Why Region Matters More Than Anything

Impuesto sobre Sucesiones y Donaciones (ISD) — Spain's inheritance and gift tax — is a tax on the person receiving the estate, not on the estate itself. There is no single estate-wide bill like UK Inheritance Tax: each heir is taxed individually on their share, at progressive rates from 7.65% to 34%, with multipliers based on how closely related they were to the deceased.

The framework sits in Ley 29/1987 ↗, but each of Spain's 17 autonomous communities sets its own reductions, allowances and bonificaciones. The result is a postcode lottery: the same €500,000 estate passing to the same child can produce a bill of €0 in Madrid or Andalucía and over €100,000 in Cataluña or Asturias.

Non-resident heirs of Spanish assets also fall within scope. The ECJ ruled in C-127/12 that Spain could not discriminate against non-residents — so since 2015 a non-resident heir can choose to apply the rules of the autonomous community where the asset is located. Filings go through Agencia Tributaria ↗ for non-residents and the regional tax authority for residents.

The 6 Things Every Expat Needs to Understand About Spanish Inheritance Tax

ISD sits at the intersection of national law, regional rules and cross-border treaties. The core ideas, though, are straightforward — once you know them the regional differences make sense.

Who Pays

Heirs and beneficiaries — not the estate. Spanish-resident heirs pay on their worldwide inheritance. Non-resident heirs pay only on Spanish-situated assets (property, bank accounts, shares in Spanish companies). The deceased's residency matters too, as it sets which regional rules apply by default.

Region Sets the Rates

National law sets a floor — autonomous communities top it up with allowances, reductions and bonificaciones. Madrid, Andalucía, Cantabria and Murcia have eliminated most direct-family tax; Cataluña, Asturias and Castilla y León remain materially heavier. Where the deceased lived (or where the asset sits, for non-residents) decides the regime.

Direct-Family Reductions Vary 0% to 99%

Children, spouses and parents (Groups I and II) receive the most generous treatment everywhere — but how generous varies enormously. Some regions exempt almost the whole estate. Others give a modest €15,956 allowance and tax the rest at full rates.

Madrid: 99% Reduction for Spouse and Children

The Comunidad de Madrid applies a flat 99% bonificación to inheritance tax for Groups I and II (descendants, ascendants, spouse). A surviving spouse inheriting €1m typically pays around €2,000–€3,000 instead of €200,000+. See Madrid Hacienda ↗.

Andalucía: Near-Zero for Direct Family

Andalucía applies a 99% bonificación for Groups I and II plus a €1,000,000 personal allowance per heir. For most British, Irish and Northern European retirees on the Costa del Sol passing to children, the resulting tax bill is effectively zero. See Junta de Andalucía Hacienda ↗.

Real Bills in Cataluña and Asturias

Cataluña offers tiered bonificaciones that taper away on larger estates — meaningful tax kicks in above roughly €100,000–€200,000 per heir. Asturias has the highest top brackets in the country (up to 36.5%) and limited reductions. Holiday-home owners in these regions should plan carefully. See ATC Cataluña ↗.

Eight Real-World Expat Scenarios

The rules sound abstract until you map them to an actual family. These are the inheritance scenarios we see most often — and how ISD plays out in each.

  • UK retiree leaves Spanish estate to British children: A British resident in Málaga dies leaving a €700,000 estate to two UK-resident children. Because the deceased was Andalucían resident, Andalucía's rules apply — and the UK-resident children can use that same regime under ECJ C-127/12. Net Spanish ISD: typically near zero.
  • Costa Blanca holiday home passes to grandchildren: An English couple jointly owns a Valencia holiday home. On the second death it passes to three grandchildren. Valencia (ATV ↗) applies a 99% bonificación to Group I descendants and extends similar treatment to many Group II descendants — but adult grandchildren may face a smaller reduction. Worth planning before the second death.
  • Madrid resident leaves everything to spouse: A retired American in Madrid leaves her whole estate to her surviving husband. Madrid's 99% bonificación reduces what would have been a six-figure bill to a token amount, usually under €5,000. The spouse still has to file Modelo 650 within six months.
  • Andalucía retiree leaves estate to two children: A British widower in Marbella with a €900,000 estate passes to one daughter in the UK and one son in Spain. Both heirs can apply Andalucía's rules — €1m personal allowance per heir plus 99% bonificación. Tax bill on the Spanish-situated assets: effectively zero.
  • Deceased non-resident with Spanish property: A French national in Paris owns a holiday flat in Barcelona, left to her two children. The default regime is national — but the heirs can elect to apply Cataluña's rules under EU non-discrimination. Sometimes regional is better, sometimes national; both need modelling.
  • Dual national estate (UK and Spain): A British-Spanish dual national resident in Valencia dies leaving Spanish property plus a UK pension and ISA. The Spanish-resident heirs are taxed on their worldwide share under ISD. The UK assets may also trigger UK IHT. There is no UK-Spain treaty for inheritance, so unilateral relief is essential — see HMRC's guidance on foreign assets ↗.
  • Common-law partners (parejas de hecho): An unmarried Dutch couple in Cataluña, registered as pareja de hecho, one partner dies leaving everything to the survivor. In Cataluña, registered partners are treated as Group II (spouse equivalent). In some other regions an unregistered partner falls into Group IV with multipliers up to 2.4x — a catastrophic outcome. Registration matters.
  • Spaniard residing in the UK passing to Spanish heirs: A Spanish national who has lived in London for 20 years dies leaving a Bilbao flat and UK assets, with Spanish-resident siblings as heirs. The siblings (Group III) are taxed on the Spanish-situated assets under Basque Country rules — País Vasco has its own foral regime with more generous direct-family treatment and different sibling rules.

6 Costly Mistakes Expats Make With Spanish Inheritance Tax

Most ISD disasters come from one of these six errors — not from the tax itself but from a misunderstanding of how it works.

  • Assuming UK IHT and Spanish ISD work the same way: They do not. UK IHT taxes the estate; ISD taxes each heir individually. UK has a £325,000 nil-rate band; Spain's allowances depend on relationship and region. UK lets you leave everything to a spouse tax-free; Spain only gets you there in certain regions. Plan separately for each.
  • Not making a Spanish will: Without one, your Spanish assets pass under your country-of-origin succession law (EU Regulation 650/2012) but the practical process is far slower, more expensive and more easily contested. A short, region-appropriate Spanish will sitting alongside your UK or US one is essential for any expat property owner.
  • Missing the six-month filing deadline: ISD must be filed within six months of death. You can request a single six-month extension but only within the first five months. Miss the window and you face surcharges of 5%, 10%, 15% or 20% plus interest — and you cannot register the property in the heir's name until ISD is paid.
  • Ignoring autonomous community rules: Defaulting to "Spanish inheritance tax is terrible" without checking the region produces enormous bad decisions — unnecessarily aggressive gifting, panic property sales and trust structures that do not work in civil law. Always model the actual region first.
  • Joint ownership confusion: Many British couples assume a jointly-owned Spanish property automatically passes to the survivor like UK joint tenancy. Spanish co-ownership (proindiviso) does not. The deceased's half passes under their will and triggers ISD for the spouse. Plan title structure at purchase.
  • Not planning lifetime gifts: The "D" in ISD is the same regime as inheritance — and several regions including Madrid and Andalucía apply similar bonificaciones to lifetime gifts to direct family. Used well, this passes assets down gradually with minimal tax. Used badly, it triggers Spanish gift tax, possibly UK capital gains tax, and rolls into the seven-year UK IHT clock.

Why Expats Take Out Funeral Insurance Through 247 Expat Insurance

A Spanish funeral has to be arranged within 24–48 hours of death. Inheritance tax has to be filed within six months. Both fall on the same grieving family. A funeral plan covers the first crisis so your heirs aren't selling assets or borrowing money to pay for either — and it gives them six clear months to handle ISD properly.

Spanish Inheritance Tax Frequently Asked Questions

How much is inheritance tax in Spain?
The national base scale runs from 7.65% on the first €7,993 up to 34% above €797,555 — but the final figure depends almost entirely on the autonomous community. Direct family in Madrid, Andalucía, Cantabria or Murcia often pays effectively nothing. Direct family in Cataluña or Asturias can pay tens or hundreds of thousands on a substantial estate. Always model your actual region.
What are the four heir groups under Spanish ISD?
Group I: Descendants under 21. Group II: Descendants 21+, spouses, ascendants. Group III: Siblings, nieces, nephews, aunts, uncles, in-laws. Group IV: Cousins, unrelated heirs, unregistered partners. National multipliers escalate sharply from Group I to Group IV — leaving an estate to a friend or unregistered partner can result in a tax bill more than double the equivalent left to a child.
How long do heirs have to pay Spanish inheritance tax?
Six months from the date of death, with one possible six-month extension if requested in the first five months. After that, surcharges of 5% (within 3 months late), 10%, 15% or 20% (over a year late) apply, plus late-payment interest. Crucially, you cannot register Spanish property in the heir's name at the Land Registry until ISD is paid or formally exempted.
Do non-resident heirs pay Spanish inheritance tax?
Yes, on Spanish-situated assets — property, Spanish bank accounts, Spanish company shares. Since 2015, following ECJ ruling C-127/12 ↗, non-resident heirs (within and outside the EU/EEA) may elect to apply the regional rules of the community where the asset is located, rather than the harsher national-only regime. Filings go through Agencia Tributaria's non-resident portal ↗.
Is there a UK-Spain inheritance tax treaty?
No. The UK and Spain do not have a specific double tax treaty for inheritance and gift taxes. Relief from double taxation depends on unilateral provisions in each country — UK IHT can give credit for foreign tax paid on foreign-situs assets under the right conditions, and Spain allows credit for foreign tax under Article 23 of Ley 29/1987 ↗. Cross-border estates almost always need professional advice on both sides.
How does a funeral insurance policy help with inheritance tax?
It doesn't reduce the tax — but it protects the family in three practical ways. First, it covers the cost of a Spanish funeral immediately, when bank accounts may still be frozen. Second, it usually pays out within days, giving heirs liquidity to engage a gestor and start the ISD process. Third, on most Spanish funeral and life policies the payout to a named beneficiary sits outside the probate (partición) process, which keeps cash flowing while the rest of the estate is sorted.
