A spouse or child inheriting a Spanish home in the Comunidad Valenciana in 2026 pays roughly 1% of the standard inheritance tax bill, thanks to a 99% autonomous bonus. Cross the border into the Region of Murcia and the same relative pays the same 1%. Cross into Asturias or Castilla y León and the same inheritance produces a five-figure bill. The region, not the state, decides most of what heirs actually owe.

This guide covers the Impuesto sobre Sucesiones y Donaciones (ISD) as it applies to a Spanish property inherited in 2026, with the procedure, the regional rates that matter on the Costa Blanca and Costa Cálida, and the traps that catch foreign families most often.

## What is Spanish inheritance tax and who has to pay it?

ISD is a national tax created by Ley 29/1987 and developed by Real Decreto 1629/1991, but its collection and most of its rules have been ceded to the seventeen autonomous communities. The heir pays, not the estate. Every beneficiary files a separate return for the share received, on **Modelo 650**.

The tax reaches anyone who inherits a Spanish asset, regardless of where the heir lives or what passport they hold. A British son living in Manchester who inherits his father's apartment in Torrevieja is liable in Spain even if his father was also non-resident. What changed after the Court of Justice of the European Union ruling in case C-127/12 (2014), and after Ley 26/2014 and later Supreme Court decisions, is that non-residents from any country, EU or not, may apply the rules of the Spanish autonomous community where the property is located. That single point is worth thousands of euros in the regions Wesna covers.

The heir class matters. Spanish law divides beneficiaries into four groups:

- **Group I**: descendants and adopted children under 21.
- **Group II**: descendants 21 or older, spouses, ascendants.
- **Group III**: siblings, nephews, nieces, in-laws, aunts and uncles.
- **Group IV**: cousins, unrelated heirs, unmarried partners not registered as pareja de hecho.

Most autonomous bonuses apply only to Groups I and II. A cousin or an unmarried partner inheriting a Costa Blanca villa pays close to the state scale, whatever the region.

## How does the inheritance procedure work step by step?

The process is administrative and notarial. There is no probate court unless someone contests the will. In outline:

1. **Get the death certificate and legalise it.** A foreign certificate needs the Hague Apostille and a sworn translation into Spanish.
2. **Request the Certificado de Últimas Voluntades and the Certificado de Contratos de Seguros** from the Ministry of Justice, fifteen working days after the death. These confirm whether the deceased left a Spanish will and whether any life insurance names beneficiaries.
3. **Obtain the Spanish will**, or, if there is none, open a foreign will and have it recognised, or file a declaration of heirs (declaración de herederos ab intestato) at a Spanish notary.
4. **Get NIE numbers for every heir.** No NIE, no tax return, no registration. See the [NIE guide for foreigners](/blog/nie-for-foreigners-in-spain).
5. **Compile the inventory.** For each Spanish property the notary needs the escritura, the nota simple from the Registro de la Propiedad, the cadastral reference and the last IBI receipt. Our [nota simple explainer](/blog/escritura-vs-nota-simple-spain-2026) covers what appears on that document.
6. **Sign the Escritura de Aceptación y Adjudicación de Herencia** before a Spanish notary. If heirs cannot travel, a notarised and apostilled [power of attorney](/blog/power-of-attorney-spain-property-purchase-2026) lets a lawyer sign on their behalf.
7. **File Modelo 650 and pay ISD** within six months of the date of death. A one-off six-month extension can be requested inside the first five months.
8. **Pay plusvalía municipal** at the town hall on the same six-month deadline. This is a separate municipal tax on the increase in cadastral land value.
9. **Register the inheritance** at the Registro de la Propiedad. The new owners appear on a fresh nota simple within a few weeks.
10. **Update the Catastro and the IBI padrón** so future bills are issued in the new owners' names.

Where ISD is filed depends on residency. If the deceased was a Spanish resident, the return goes to the autonomous community where they had their habitual residence, applying that community's rules. If the deceased was non-resident, the return goes to the Oficina Nacional de Gestión Tributaria in Madrid, but the heirs may elect the rules of the autonomous community where the most valuable Spanish asset sits. For a family whose only Spanish asset is a flat in Torrevieja, that means the rules of the Comunidad Valenciana apply.

The official guidance and the current version of Modelo 650 are published on the [Agencia Tributaria site](https://sede.agenciatributaria.gob.es/Sede/impuestos-tasas/sucesiones-donaciones.html).

## What are the regional rates and allowances in 2026?

The state scale runs from 7.65% on the first EUR 7,993 of the taxable base to 34% above roughly EUR 800,000, with a multiplier of 1 to 2.4 depending on the group and the heir's pre-existing wealth. The number that actually gets paid is far lower once the autonomous bonus applies. The table below shows what a Group I or II heir (spouse, child, parent) faces in 2026 in the regions where Wesna sells, plus a couple of comparators.

| Region | Group I & II bonus | Effective ISD on a EUR 300,000 property inherited by a spouse | Notes |
|---|---|---|---|
| Comunidad Valenciana | 99% bonification | around EUR 500 to 700 | Applies from May 2023, confirmed for 2026 |
| Región de Murcia | 99% deduction | around EUR 500 to 700 | Applies to Groups I and II |
| Comunidad de Madrid | 99% bonification | around EUR 500 to 700 | Long-standing, extended to some Group III |
| Andalucía | 99% bonification plus EUR 1,000,000 allowance | usually EUR 0 | Very heir-friendly |
| Islas Baleares | up to 100% for Group I, 50% and up for Group II | often EUR 0 to a few thousand | Reformed 2023 |
| Cataluña | 99% for Group I, sliding 60% down to 0% for Group II | often five figures | Reformed 2023, less generous than Valencia |
| Asturias | no general bonus | tens of thousands | State scale largely intact |
| Castilla y León | limited allowance | five figures | State scale largely intact |

Group III and Group IV heirs get little relief anywhere. A niece inheriting the same EUR 300,000 flat in Torrevieja can face a bill of EUR 40,000 to 60,000 after the 1.5882 or 2 multiplier is applied to the state scale. That is the single largest reason to write a Spanish will that names spouse and children rather than nephews or godchildren.

The taxable base is the **valor de referencia** published by the Catastro when it exists, or the market value if it does not. Since 2022 the Catastro's reference value has been the legal minimum for both purchase transfer tax and inheritance tax. Declaring less than that value triggers a valuation review. If the reference value looks inflated compared with the real market, there is a formal challenge route, but it must be filed inside the standard four-year limitation period.

## What traps catch foreign heirs most often?

**Missing the six-month deadline.** Interest and a surcharge of 5% to 20% attach automatically. If the delay is discovered by the tax office rather than voluntarily corrected, the sanction is heavier. Request the six-month extension inside the first five months; it is granted almost automatically and buys real time to translate documents.

**Assuming the region does not matter.** Heirs sometimes file at the national office under state rules because a lawyer in their home country tells them to. This can multiply the bill by fifty or a hundred. Non-residents have the right to apply the rules of the community where the property sits; that right is worth using.

**Forgetting plusvalía municipal.** This is a town-hall tax, not part of ISD, and has its own six-month clock. After the Constitutional Court ruling of October 2021 and the new calculation rules in Real Decreto-ley 26/2021, heirs can choose between the objective method and the real-gain method, whichever produces a lower bill. Ask for both calculations.

**Ignoring the Spanish will question.** A property owner who dies with only a foreign will forces heirs to have that will recognised, translated, apostilled and interpreted. In practice this adds three to six months and legal fees of several thousand euros. A two-page Spanish will signed at any Spanish notary costs around EUR 60 to 90 and eliminates the problem. Under EU Regulation 650/2012 a testator may choose the law of their nationality to govern succession; that choice belongs in the will itself.

**Undeclared bank accounts and life insurance.** ISD applies to the deceased's Spanish assets as a whole, not just the property. A dormant account with EUR 8,000 in it, or a mortgage life insurance policy that pays off the loan on the flat, both belong in the return. The Certificado de Contratos de Seguros catches the second one every time.

**Selling before registering.** The new owners cannot sell, mortgage or seriously renovate until the Escritura de Aceptación is signed, ISD is paid and the Registro is updated. Buyers walking away because of an unregistered inheritance is a common file at any Costa Blanca notary.

**Confusing ISD with annual non-resident tax.** ISD is a one-off event on inheritance. The [annual non-resident income tax on Spanish property](/blog/annual-property-taxes-spain-non-resident) via [Modelo 210](/blog/modelo-210-non-resident-tax-spanish-property-2026) continues in the heirs' names from the day after death, and [IBI](/blog/ibi-spain-2026-property-tax-explained) is due to the municipality as usual.

**Underestimating legal cost.** Budget EUR 2,000 to 5,000 in lawyer and notary fees for a straightforward one-property, two-heir inheritance, more if there is no Spanish will or if heirs live abroad. Our [lawyer fees guide](/blog/spanish-lawyer-fees-2026-property-purchase-cost) covers the ranges. A [notary](/blog/spanish-notary-2026-what-they-do-and-dont) charges by tariff on the escritura value, not by hour.

## Frequently asked questions

**Do non-EU heirs pay more than EU heirs on Spanish inheritance?**

No, not since 2018. The Spanish Supreme Court extended the 2014 ECJ ruling to residents of third countries, and Agencia Tributaria has accepted this in successive resolutions. A Norwegian, British or Dutch heir inheriting a property in Torrevieja may apply the Comunidad Valenciana rules on the same footing as a Spanish resident. The same equal treatment applies to Ukrainian heirs. Russian heirs are entitled to the same tax treatment, though sanctions screening at the bank stage can slow the actual payment of ISD.

**Is there a foreign tax credit if I also pay inheritance tax in my home country?**

Spain grants a unilateral credit under article 23 of Ley 29/1987 for foreign inheritance tax paid on the same assets, up to the Spanish tax on those assets. Spain has few bilateral inheritance tax treaties (with France, Sweden and Greece). UK, German, Dutch and Nordic heirs usually rely on the domestic credit in their own country to avoid double taxation. Take specialist advice in the country of residence.

**What happens if I simply do not file?**

The tax office can reassess for four years plus the six-month filing period. Because the property cannot be registered in the heirs' names without proof of ISD payment, the problem surfaces the moment anyone tries to sell, mortgage or refinance. Late filings after four years and one day fall outside the limitation period, but the property remains legally frozen in the deceased's name until the escritura de aceptación is signed and ISD is settled, however small the bill.

**Can heirs sell the property to pay the tax?**

Not before signing the escritura de aceptación de herencia. Some notaries will accept a simultaneous acceptance and sale on the same day, with ISD paid from the sale proceeds through the notary. This needs coordination between both lawyers and works only when the tax is small relative to the price, which is exactly the case in Valencia, Murcia, Madrid and Andalucía.

**Does a mortgage on the property reduce the inheritance tax base?**

Yes. The outstanding mortgage balance at the date of death is deducted from the property value in the tax base. So is any pending IBI, community fee or utility debt attached to the property. Life insurance that pays off the mortgage is added back as a separate taxable amount for the beneficiary.
