Receiving an Inheritance in Spain: What to Check, and the Tax Clock That's Already Running

The paperwork side of receiving an inheritance in Spain runs on a strict clock that starts the day someone dies, whether or not you've found out yet, or even know you're an heir. This guide covers how to check whether you are, what the tax actually costs (which depends enormously on which region you're in), the option most people don't know exists to protect yourself from a deceased person's debts, and what changes specifically if the person who passed away was a foreign citizen.

How to find out if you're part of a will

The starting point is the certificado de últimas voluntades (last will certificate), issued by the Registro General de Actos de Última Voluntad at the Ministry of Justice — it tells you whether a will exists and, if so, before which notary, though not what it says. You can't request it until 15 business days after the death, and need the official death certificate plus a completed Modelo 790 form; it costs €3.86 and typically takes 5-10 business days to arrive depending on how you apply, according to BBVA's guidance. Once you know which notary holds the will, you (or anyone with a legitimate interest) can request a copy of the actual document from them.

If the certificate comes back showing no will was ever registered, Spain falls back to the same intestate order covered in our companion guide on planning your legacy and inheritance in Spain: descendants first, then ascendants, then the surviving spouse, then collateral relatives up to the fourth degree. Establishing who legally qualifies in that case requires a notarial declaración de herederos abintestato.

The tax clock: 6 months, and it's already running

Spain's Impuesto sobre Sucesiones y Donaciones (ISD), filed via Modelo 650, has to be filed and paid within 6 months of the date of death — not from when you find out, not from when the paperwork is ready. You can request a one-time 6-month extension, but only if you apply within the first 5 months, and interest accrues on the extended period, according to VisorFiscal's regional breakdown. Miss the deadline without requesting an extension and you face a 5-20% surcharge if you file late voluntarily, or a much steeper 50-150% penalty if the tax authority catches the omission first — a real reason to start the paperwork as soon as you reasonably can, not once everything feels fully resolved.

A separate tax, the plusvalía municipal (a town-hall tax on the increase in a property's land value), applies whenever you inherit real estate, and runs on the same 6-month clock, also extendable — but this one is paid to the local council, not the tax agency, and each heir pays their proportional share, according to GESTISYD. Many town halls offer bonifications of 50-95% when the property was the deceased's habitual residence and the heirs are close family, so it's worth checking your specific municipality's rules before assuming the full amount is due.

Why your region changes the bill dramatically

ISD is a tax ceded to the autonomous communities, meaning each region sets its own reductions and bonifications on top of the national framework — and the difference between regions is not a rounding error. Your relationship to the deceased sorts you into one of four kinship groups that set your base reduction: Group I (descendants under 21), Group II (descendants 21+, spouse, ascendants), Group III (siblings, aunts and uncles, nieces and nephews), and Group IV (cousins and unrelated people), according to VisorFiscal — the more distant the relationship, the smaller the reduction and the higher the rate multiplier applied on top.

Where that really shows up is the regional bonification layer. In Madrid, close family (Groups I-II) get a 99% bonification on the resulting tax, making it close to symbolic — and Madrid extended a bonification to Group III too, raised from 25% to 50% in July 2025, per INEAF's coverage. Andalucía applies bonifications of 99-100% for Groups I-II as well. Other regions are far less generous. This is precisely the kind of figure worth checking for your specific autonomous community before assuming a number you heard from a friend or relative in a different region applies to you — it very often doesn't.

Life insurance proceeds are taxed under the same ISD framework, but with their own separate reduction: close family beneficiaries (spouse, ascendant, descendant, or adopted child) get a 100% reduction on the first €9,195.45, according to Acierto — but that reduction disappears entirely if the beneficiary is a third party (a friend, an unregistered unmarried partner, a distant relative), who instead faces the full rate and multiplier structure from the first euro.

Accepting, limiting your liability, or walking away

Something worth knowing before you sign anything: you don't have to accept an inheritance exactly as it comes. Aceptación pura y simple (straightforward acceptance) makes you personally liable for the deceased's debts with your own assets, even beyond what you actually inherit, if the estate turns out to owe more than it's worth. Aceptación a beneficio de inventario, regulated under Código Civil arts. 1010-1034, caps your liability at the value of what you actually inherit — if the estate's debts exceed its assets, you don't have to cover the difference out of your own pocket, according to El Notario and Martín Parés. You can also simply renounce (renunciar) the inheritance entirely. If you have any real uncertainty about whether the deceased had significant debts, accepting a beneficio de inventario is the protective default worth discussing with a notary before you accept anything outright.

How to prepare: the practical checklist

Receiving an inheritance in Spain from a foreign citizen

This scenario splits into two genuinely different questions people often conflate: what law governs how the estate gets divided, and what tax you personally owe in Spain. They're not the same question, and get different answers.

Which law applies to the succession is governed, for deaths since August 2015, by the EU Succession Regulation (Reglamento (UE) 650/2012): the general rule points to the law of the deceased's last habitual residence, unless they explicitly chose the law of their own nationality in a will — a choice known as professio iuris — according to the OCW UC3M materials and coverage from Noticias Jurídicas. Practically: if a foreign national lived in Spain and never made that choice, Spanish succession law — including the legítima forced-heirship rules covered in our companion guide — can end up governing their entire estate, which sometimes surprises heirs expecting the fully free testamentary system of the deceased's home country.

What you owe in Spanish tax is a separate question, governed by your own residence, not the deceased's nationality. Under LISD art. 6, if you are a Spanish tax resident, Spain taxes you by obligación personal — on everything you inherit worldwide, regardless of where the deceased lived or where the assets are situated — simply because you are the Spanish resident, according to Ruiz Ballesteros. That means a Spanish resident inheriting entirely foreign-situated assets from a foreign relative still has to file and pay Spanish ISD. To avoid paying twice, LISD art. 23 provides a credit for foreign inheritance tax already paid abroad — capped at the lesser of what you actually paid abroad or the proportional Spanish tax on those same assets. Spain has dedicated inheritance tax treaties with only France, Greece, and Sweden, so for inheritances from most other countries, this unilateral domestic credit is your only relief mechanism, not a bilateral treaty.

For the practical mechanics of actually receiving assets across borders: within the EU, a Certificado Sucesorio Europeo (European Certificate of Succession), issued in the country of the deceased's residence or death, lets you prove your status as heir directly to Spanish notaries and registries without a separate Spanish probate process, according to coverage on the topic. Outside the EU, foreign documents (the will, death certificate, birth certificates) generally need to be legalized (apostilled) and officially translated before a Spanish notary will accept them. If you don't already have one, you'll need an NIE, since it's required for essentially all Spanish tax and registry paperwork — and much of this process, with proper legal representation, can now be handled remotely without traveling to Spain.

Other points worth knowing

The 6-month tax clock starts on the date of death regardless of when you personally find out you're an heir or where you live — if you're abroad, or the news reaches you late, the deadline doesn't move, which is exactly why requesting the certificado de últimas voluntades and starting the paperwork promptly matters even when everything else feels unresolved. And if you inherit a property you don't intend to live in or rent out immediately, it's worth pricing in what it costs to simply hold it — our vacant house cost calculator covers exactly that calculation.

Quick answers

Do I have to accept an inheritance I don't want? No — you can formally renounce it. That's a real option worth considering if the estate's debts are uncertain or likely larger than its assets, though accepting a beneficio de inventario is often the better middle ground since it still lets you receive any net value while capping your risk.

What if I live outside Spain and inherit Spanish property? The 6-month deadline still applies, and Modelo 650 for non-residents is filed with Spain's Oficina Nacional de Gestión Tributaria rather than a regional office. You'll need an NIE and, in most cases, a fiscal representative in Spain — this is a case where professional help genuinely pays for itself.

Does the reduction on regional bonifications like Madrid's 99% apply automatically? No — it has to be correctly claimed on the Modelo 650 filing, within the deadline, for your specific autonomous community's rules. This is exactly the kind of detail worth having a gestor confirm rather than assuming.

This article offers general, educational information about receiving an inheritance in Spain and does not constitute legal or tax advice. ISD rules vary significantly by autonomous community, cross-border succession law is genuinely complex, and deadlines are strictly enforced — consult a notary, gestor, or lawyer specializing in successions promptly after a death, and verify current rules with AEAT or your regional tax authority before filing.
