Spanish Inheritance with a Non-Resident Heir: How Inheritance Tax Works

It is increasingly common for an inheritance in Spain to involve heirs living in the United Kingdom, France, the United States or other countries. When an heir is not a Spanish tax resident, Inheritance Tax has specific rules that should be reviewed carefully. In this guide we explain which regulations may apply, what deadlines exist, and how to avoid double taxation issues or common mistakes when filing Form 650.

When is an heir considered a non-resident in Spain

Tax residence is the first thing to clarify, because it determines how the inheritance will be taxed. As a general rule, a person is a Spanish tax resident if they spend more than 183 days in Spanish territory during the calendar year, or if Spain is the main centre of their economic activities or interests. Anyone who does not meet those criteria is treated, for tax purposes, as a non-resident.

A few practical examples:

If you are unsure about your tax residence, it is worth reviewing in detail, because the residence certificate issued by your home tax authority plays a key role in the rest of the procedure.

What regulations apply to Inheritance Tax

This is one of the points that raises the most questions in cross-border inheritances.

The Spanish Inheritance and Gift Tax (ISD) is a state tax, but it has been transferred to the Autonomous Communities, which can set their own reductions and allowances. Historically, non-resident heirs could only apply the state regulations, which in many cases meant a much heavier tax bill than that paid by a resident heir in an equivalent situation.

Generally, after the relevant case-law evolution, non-resident heirs may apply the Autonomous Community regulations that correspond to their case instead of the state regulations. The CJEU judgment of 3 September 2014 (case C-127/12) and the subsequent doctrine of the Spanish Supreme Court in 2018 opened that possibility, first for EU/EEA residents and later also for residents outside the European Union.

In practice, the differences between state and regional regulations can be very significant, so each case should be reviewed individually. The same inheritance can result in a substantially reduced tax bill or a significantly higher one depending on which Autonomous Community applies.

How the applicable Autonomous Community is determined

If the deceased was a Spanish resident

The regulations of the Autonomous Community where the deceased had their habitual residence during the five years before death apply. For example, if the deceased lived in Valencia, Valencian regulations apply, even if the heir lives in the United Kingdom.

If the deceased was a non-resident

The regulations of the Autonomous Community where the highest-value asset of the estate is located apply, typically a property. For example, if the deceased lived in France but owned a flat in Madrid, the regulations of the Madrid region apply.

It is common to see clients assume that, “as a non-resident, the state regulations always apply by default”. In most cases that is no longer the situation.

What happens if the inheritance includes a property in Spain

The most common case is an inheritance that includes a home, a commercial unit or a plot of land in Spain. The administration involves several practical steps:

If the heir keeps the property and remains a non-resident, in subsequent years they will need to file Form 210 annually for imputed income (if the property is empty) or for rental income (if it is let). It is a recurring obligation that should be planned for from the outset.

Other taxes and costs that may arise in an inheritance

Many heirs only think of Inheritance Tax and are then surprised by additional costs. It is best to have the full picture from the start:

  1. Plusvalía municipal (Spanish municipal capital gains tax on the increase in the value of urban land). If the inheritance includes urban property, the city council where the property is located may charge this local tax, with its own deadlines and allowances. It does not depend on the Autonomous Community: it is strictly local.
  2. Subsequent NRIT (Form 210). If the heir keeps the property and does not reside in Spain, they will need to declare imputed income or rental income annually. More detail in our non-resident services page.
  3. Notary and registry fees. The deed of acceptance of the inheritance before a notary, plus the subsequent registration at the Land Registry, involves additional costs that depend on the value of the assets.

These costs add to Inheritance Tax and should be factored into the overall budget when planning the estate administration.

Deadlines and obligations for a non-resident heir

The general filing deadline for Inheritance Tax is 6 months from the date of death. It can be extended for another 6 months, provided that the extension request is filed within the first 5 months of the initial period.

Forms to file:

The competent authority is the relevant Autonomous Community or, in some cases, the National Tax Management Office (ONGT) of the Spanish Tax Agency.

If filed late without prior request, Law 11/2021 set a progressive surcharge system: 1% plus an additional 1% per full month of delay, up to 12 months. Beyond 12 months, the surcharge rises to 15% plus late-payment interest.

If the heir does not yet have a NIE (Spanish foreign tax identification number), it must be obtained before filing anything. It can be requested from abroad through the Spanish consulate or, alternatively, through a power of attorney granted to a representative in Spain (a tax adviser, lawyer or gestor) who applies for the NIE on the heir's behalf.

International double taxation

One of the most common questions is: “if I pay Inheritance Tax in Spain, do I have to pay again in my country of residence?”. The answer depends on the bilateral framework.

Spain has signed bilateral treaties to avoid double taxation on inheritances with a limited group of countries, including France, Sweden and Greece. If the heir resides in any of those countries, the treaty sets rules to allocate taxing rights between both States and avoid paying twice.

Where there is no specific treaty, the Spanish Inheritance and Gift Tax Act allows a unilateral deduction for tax paid abroad: the heir can deduct the foreign tax (within certain limits) when settling the Spanish tax.

In practice, we see many heirs who only realise late that they can deduct what they paid abroad, because they were unaware of the bilateral framework. It is best to review the bilateral situation of the country of residence before filing, not after.

Required documentation

The minimum documentation usually needed for an inheritance with a non-resident heir:

Common mistakes in cross-border inheritances

From the cases we see every year, the same mistakes recur:

  1. Assuming that the state regulations apply “by default”, when in many cases the more favourable regional regulations can be applied.
  2. Failing to check whether a double-taxation treaty exists with the heir's country of residence.
  3. Forgetting the plusvalía municipal of the city council where the property is located, which has its own deadline and is sometimes processed in parallel with Form 650.
  4. Miscalculating the 6-month deadline when the heir is abroad and is informed of the death late. The deadline runs from the date of death itself, not from the date the heir receives the news.
  5. Trying to file Form 650 without first obtaining the heir's NIE. The Tax Agency will not accept the filing.

Frequently asked questions

What if the heir lives outside the EU?

After the relevant case-law evolution, non-resident heirs (including those outside the EU/EEA) may apply the regional regulations that correspond to them, instead of the state regulations.

Do I have to travel to Spain to file Form 650?

It is not strictly required. Filing can be done through a tax representative or adviser acting on your behalf with a power of attorney.

Is appointing a tax representative mandatory?

In certain situations, particularly for residents outside the EU/EEA, it may be mandatory. It is worth reviewing each case individually.

What tax do I pay in my country of residence?

It depends on the applicable treaty. As a general rule, if your country also taxes inheritances, you will be able to deduct what you paid in Spain. It is advisable to consult a local tax adviser as well.

How long does the full process take?

If the documentation is complete, filing the Inheritance Tax return can be done within a few weeks. The subsequent registration at the Land Registry can take longer.
