You are not Spanish. You do not live in Spain. You own a villa on the Golden Mile, or you are close to buying one. When the question of succession arises — as it will, eventually, if you are thinking seriously about an asset at this price — the instinct is often to assume that Spanish tax law is someone else's problem. It is not. Spain taxes the Spanish asset regardless of where the deceased lived, and regardless of where the heir lives. The jurisdiction of the property is what matters.
That is the starting point. What follows is somewhat more reassuring than the starting point suggests.
The tax itself
The *Impuesto sobre Sucesiones y Donaciones* — ISD — is Spain's inheritance and gift tax. It applies to transfers of wealth, whether on death or by gift during one's lifetime. For non-residents inheriting a Spanish-situs asset, the liability falls on the heir, not the estate. Each heir is assessed individually, on the value of what they receive.
The tax is administered at regional level, and the region matters enormously. Andalucía — which covers Marbella, Benahavís, Sotogrande, and the rest of the Costa del Sol — has in recent years become one of the most favourable jurisdictions in Spain for inheritance. The figures are not subtle: direct heirs in Groups I and II (spouses, children, parents, and grandparents) currently benefit from a 99% *bonificación* on their ISD liability. In practical terms, that reduces the tax to a rounding error for the typical luxury-property succession.
It is worth pausing on what 99% means in practice. If the gross ISD liability on a €5 million inheritance were calculated at, say, €800,000, the heir pays 1% of that — roughly €8,000. The bonification does not eliminate the process; it effectively eliminates the financial sting of it for qualifying heirs. As of 2026, this bonification remains in force under the current Andalusian regional government.
Who qualifies, and who does not
The Spanish ISD groups heirs into four categories. Group I covers descendants under 21. Group II covers descendants over 21, spouses, and ascendants. Group III covers more distant relatives — siblings, aunts, uncles, nieces, nephews, and in-laws. Group IV covers everyone else, including unmarried partners without legal recognition, and unrelated beneficiaries.
The 99% bonification in Andalucía applies to Groups I and II. The position for Groups III and IV is materially different. Rates for Group III can reach 15–20% or higher depending on the taxable base and prior wealth. Group IV rates can exceed 30%. For a client whose estate planning passes a significant Spanish asset to, say, a sibling or a long-term partner without registered civil status, the exposure is real and needs to be structured in advance.
Unmarried partners deserve a particular note. Spain recognises *parejas de hecho* (registered civil partnerships) at regional level, but registration requirements vary, and not all foreign relationships translate cleanly into Spanish categories. An unmarried couple who are treated as spouses in their home jurisdiction may not be treated as spouses in Spain without deliberate legal steps. We are not your tax adviser. This sets out the contour; specifics need a cross-border specialist.
Residency, non-residency, and the EU dimension
For many years, non-residents were taxed under the national ISD framework, which was considerably less generous than the Andalusian regional rules. Following a 2014 European Court of Justice ruling against Spain, the law was amended to allow EU and EEA residents to access the most favourable regional rules applicable to the transaction — which, for Andalucía, means the 99% bonification now extends to heirs resident elsewhere in the EU and the EEA.
For heirs resident outside the EU and EEA — a significant category given the concentration of non-European wealth on the Costa del Sol — the position has historically been less clear. There have been further legal developments, and the general direction has been towards equalisation, but this remains an area where the specific facts matter and where competent advice is not optional. A buyer from the Gulf, from the United States, or from Latin America should not assume their heirs will automatically access the same bonification as a German or British heir.
Post-Brexit, UK residents fall outside the EEA for these purposes. In practice, Spanish courts and tax authorities have in many cases continued to apply the regional rules by analogy, but this is not the same as a legal guarantee. British buyers — who remain a substantial presence on the Golden Mile and in the Marbella Golden Mile broadly — should seek specific confirmation on this point.
The six-month clock
The procedural dimension of Spanish inheritance is where many families encounter unexpected friction, not because the law is punitive, but because the timeline is compressed relative to what most jurisdictions require.
From the date of death, heirs have six months to file the ISD declaration and, where applicable, pay the tax. This clock applies regardless of where the deceased lived, where the heirs live, or how complex the estate is. Missing the deadline does not invalidate the inheritance, but it attracts surcharges: 5% after six months, 10% after twelve months, 15% after fifteen months, and 20% plus interest after eighteen months. The surcharges compound the inconvenience of an already demanding process.
An extension of six months is available, but it must be applied for within the first five months of the six-month period — not at the end of it. In practice, heirs who are not already engaged with Spanish legal advisers at the time of death often discover the deadline after it has begun to run. Appointing a Spanish *gestor* or lawyer with power of attorney before any succession event is not overcaution; it is basic estate hygiene for any non-resident holding Spanish property.
The notarial process
The substantive transfer of a Spanish property on death passes through the Spanish notary. The heirs must present the foreign death certificate, apostilled and translated into Spanish. If the deceased died with a Spanish will, the process is streamlined. If the deceased died without a Spanish will, the heirs must present evidence of the applicable foreign law and, typically, obtain a Certificate of Last Wills (*Certificado de Últimas Voluntades*) to confirm no Spanish will exists.
Foreign wills are recognised in Spain, and an EU Succession Certificate — available to EU residents under the 2012 EU Succession Regulation — simplifies cross-border recognition considerably. Non-EU nationals will typically rely on their national will, apostilled, with a certified translation. The process is manageable but not quick; six weeks to three months for straightforward cases is a reasonable expectation once all documents are assembled.
The notary also handles the registration of the property in the new owner's name at the Land Registry and the settlement of any *plusvalía* municipal tax — the local tax on the increase in land value since the previous transfer. *Plusvalía* is calculated by the municipality and is separate from ISD; it is typically modest in absolute terms for high-value properties, though the calculation method has been revised following a Constitutional Court ruling.
For those building a broader picture of the tax environment around a Spanish acquisition, the wider framework — including *IBI*, non-resident income tax, and capital gains considerations — is covered in the [guide to Spanish property taxes in 2026](/guides/spanish-property-tax-2026).
Planning before the event
The bonification changes the calculus significantly for direct heirs, but it does not eliminate the argument for advance planning. Structures worth examining — always with qualified advice — include whether to hold the property personally or through a vehicle, whether a Spanish will is appropriate alongside any existing testamentary documents, and whether the registered status of any partner needs formalisation before a purchase completes.
The 99% bonification is a product of Andalusian regional policy, and regional policy can change. It has been stable for several years, and no change appears imminent as of this writing, but it would be imprudent to treat the current position as permanent. Any structure that is tax-efficient only under today's rules should be stress-tested against the possibility that the rules evolve.
Off-market properties — which now represent close to half of transactions in the upper Marbella register — are often purchased and transferred within tight timelines, sometimes without the months of document preparation that a listed sale affords. The inheritance dimension should be resolved before exchange, not after.
What the picture actually looks like
For the typical client considering a property at the price levels that characterise this market — and passing it, on death, to a spouse or adult children — the Andalusian bonification makes ISD a process question rather than a financial one. The process has weight: documents, deadlines, notaries, registrations. But the cost, for qualifying heirs, is not what it appears when you first encounter the headline ISD rates.
For everyone else — siblings, partners without legal recognition, more distant beneficiaries, or heirs who fall outside the EU framework — the picture is different, and the conversation with a cross-border specialist should happen before contracts are signed.
Spain has been, for some years, quietly tidying the inheritance position for Andalucían property. The broader picture has moved in a favourable direction. That does not mean the detail takes care of itself.
