Spanish inheritance tax and succession for foreign owners

Spain taxes the beneficiary, not the estate. Each heir declares what they personally receive, so a villa left equally to three children produces three returns and three separate tax calculations. The mechanics run in four stages:

1. Taxable base. The heir's share of the Spanish assets, less their share of deductible debts and funeral costs. Property is valued at the higher of the declared value and the cadastral reference value (valor de referencia).
2. Kinship allowances. A state allowance is deducted according to which group the heir falls into, before any regional relief.
3. Progressive scale. The state scale runs from 7.65% on the first slice to 34% above roughly €797,555.
4. Multiplier coefficient. The resulting tax is multiplied by a coefficient based on the heir's relationship and their pre-existing wealth. For distant relatives and unrelated beneficiaries this can more than double the bill, taking the effective rate above 80% in extreme cases.

Unmarried couples are the group most often caught out. In several regions a pareja de hecho registered in Spain is treated like a spouse, but an unregistered partner falls into Group IV with no allowance and a doubling multiplier — which is why so much of the planning work is about documentation rather than tax rates.

The state rules above are the floor. Each autonomous community can add its own allowances and reliefs, and most have effectively abolished the tax for close family. The table below summarises the position for Group I and II heirs — spouses, children and parents — in the regions where international buyers most often own, as at September 2026.

Worked example. A €1,200,000 villa passes to two adult children,€600,000 each. In Madrid, the Balearics or Andalusia the tax after regional relief is negligible — typically a few hundred euros each. In Catalonia, after the regional allowance and taper, each child could face a five-figure bill. Same family, same value, different province.

Reliefs are set by regional law and change with regional budgets. Always confirm the rules in force at the date of death, not at the date of purchase or of reading — that is the date that fixes the position.

Historically, non-residents were pushed onto the state rules and denied the generous regional reliefs. The Court of Justice of the European Union ruled in 2014 (case C-127/12) that this discriminated against EU and EEA residents, and Spanish law was amended. Spanish Supreme Court decisions in 2018 then extended the same treatment to residents of non-EU countries, and the tax authority has applied that position since.

The practical rules for a foreign heir today:

• Non-resident heir, Spanish property. You apply the rules of the autonomous community where the Spanish asset of greatest value is located.
• Resident heir, non-resident deceased. You apply the rules of the community where you live.
• Filing point. Non-residents file with the central tax office (Agencia Tributaria, Oficina Nacional de Gestión Tributaria) rather than the regional office, but apply the regional reliefs.
• Historic overpayments. Heirs who paid on the old state-only basis have in many cases reclaimed the difference. Time limits apply, so take advice quickly if this affects an estate you administered.

Note that a non-resident is taxed only on Spanish assets. A Spanish-resident heir is taxed on worldwide inheritance, with credit for foreign tax paid. Spain has very few inheritance tax treaties — France, Greece and Sweden — so relief for UK, US or Gulf heirs comes through domestic unilateral credit rules rather than a treaty.

The return (Modelo 650) and the payment are due within six months of the date of death. This is the single most common source of avoidable cost for foreign families, because probate in the heir's home country often takes longer than six months and nobody realises the Spanish clock started on day one.

Alongside ISD, the municipality charges plusvalía municipal on the increase in the land value since the deceased acquired it. That is also due within six months, with the same six-month extension available, and it is paid to the town hall rather than the tax office.

Spanish civil law imposes forced heirship: a fixed proportion of the estate — the legítima — must pass to children, with a life interest for the surviving spouse. Some regions, notably Catalonia, the Balearics and Navarre, have their own variations. For families who want to leave everything to a spouse, or to divide an estate unevenly, that can produce an unwanted outcome.

EU Regulation 650/2012 (often called Brussels IV) allows you to elect, in your will, that the succession law of your nationality governs your whole estate instead of the law of your habitual residence. The regulation applies in Spain regardless of whether your own country participates in it, so British, Irish and other non-participating nationals can and routinely do make the election. A UK national with a Spanish holiday home can therefore elect English law and leave the property freely.

Practical points we see repeatedly:

• Make a Spanish will covering Spanish assets. It is signed before a notary, registered centrally, and avoids the delay and cost of apostilling, translating and proving a foreign will.
• Keep the two wills consistent. A later general will can inadvertently revoke an earlier Spanish one. Each should expressly state its scope.
• Make the choice of law explicit. The election must be clear on the face of the will; it is not implied by nationality.
• Choice of law is not choice of tax. Electing English or US succession law changes who inherits, not what Spanish inheritance tax is charged on the Spanish property.
• Joint ownership is not survivorship. Spain has no equivalent of the English joint tenancy: a co-owner's share passes under their will or the intestacy rules, and is taxed.

The paperwork is more demanding than most families expect, and gathering it is usually what consumes the six months. Expect to need:

• death certificate, apostilled and translated into Spanish;
• certificate from the Registro General de Actos de Última Voluntad confirming whether a Spanish will exists;
• the Spanish will, or the foreign will with grant of probate, apostilled and translated;
• a Spanish NIE for every beneficiary — apply early, it is a common bottleneck;
• the escritura and Land Registry extract (nota simple) for the property;
• the latest IBI bill showing the cadastral reference and value;
• bank certificates showing Spanish account balances at the date of death, and details of any outstanding Spanish mortgage;
• a power of attorney if the heirs cannot attend the notary in person.

Our NIE number guide sets out the three routes to obtaining a NIE and the realistic timelines, which for heirs abroad usually means applying through the consulate or by power of attorney.

Spain expects the tax to be paid before the inheritance is formalised and the property registered in the heirs' names — and the property cannot be sold or mortgaged until it is. Where the estate is asset-rich and cash-poor, that creates a genuine liquidity problem inside a six-month window.

The routes that work in practice:

• Instalments or deferral. The tax office can allow payment by instalments or a deferral in defined circumstances, with interest and often a guarantee. Apply before the deadline, not after.
• Bridging against the Spanish property. Once the escritura de aceptación de herencia is signed and the heirs are on title, a short-term facility secured on the Spanish property can settle the tax and be repaid on sale or on refinance to a term mortgage. See our Spanish bridging finance page and the cost of bridging in Spain.
• Bridging against a property at home. Where the Spanish title is not yet clean, UK or other domestic security is frequently faster — the route set out in using UK bridging for Spanish property.
• Equity release or refinance after registration. Heirs who intend to keep the property usually raise a term facility against it, either to repay the bridge or to settle the tax directly where timing allows. See equity release from Spanish property and refinancing a Spanish property.
• Inheriting a mortgaged property. The debt passes with the asset. Lenders generally require the surviving owner or heirs to be reassessed, and a non-resident heir may need to refinance onto a new facility on non-resident terms of 60–70% LTV.

One further planning point for buyers rather than heirs: how you own the property affects what your family faces later. Personal ownership, joint ownership between spouses and corporate ownership all behave differently on death — see SPV vs personal ownership and buying Spanish property through a company.
