Spanish Inheritance Tax for Non-Residents

If you inherit property, money or investments in Spain but live abroad, you may still be liable for Spanish Inheritance Tax.

Many foreigners assume that tax is only due in their country of residence. However, Spanish Inheritance and Gift Tax apply to assets located in Spain, even when the heir or beneficiary is a non-resident.

This often surprises UK expats, US citizens and other international investors who own property in Spain. Unlike the UK system, Spain does not apply a national tax-free threshold. Instead, the tax is calculated individually for each beneficiary and depends largely on the region where the asset is located.

In this guide, we explain how Spanish Inheritance Tax works for non-residents, which assets are taxable in Spain, what rates apply in 2026, how regional reductions affect the final amount, and when you may need a Spanish tax representative.

Do Non-Residents Pay Inheritance Tax in Spain?

Yes. Non-residents can be liable for Spanish Inheritance Tax if they inherit assets located in Spain.

Spain applies the source principle. This means that assets situated in Spanish territory may trigger Spanish tax, regardless of where the heir resides.

Until 2014, non-residents were often subject to less favourable tax treatment compared to residents. However, the ruling of the Court of Justice of the European Union of 3 September 2014 declared this discrimination incompatible with EU law.

As a result, non-residents can now apply the regional tax benefits corresponding to the location of the asset, in many cases under the same conditions as residents.

Therefore, even if you live abroad, Spanish regional rules may significantly reduce your tax liability. However, the applicable Autonomous Community is not determined in the same way in every case: in inheritances and life insurance proceeds, the key connecting factor is generally the deceased’s habitual residence; in gifts of real estate, the location of the property; and in gifts of other assets or rights, the habitual residence of the done. In some non-resident cases, regional rules may still apply even though the filing is made before the Spanish State Tax Administration.

Unlimited vs. Limited Tax Liability in Spain

Spanish Inheritance and Gift Tax distinguish between two types of tax liability. The difference depends on whether the heir is tax resident in Spain.

This distinction is crucial for foreigners. If you are not tax resident in Spain, you are generally taxed only on assets and rights located, exercisable or enforceable in Spain. This includes real estate, Spanish bank accounts, shares in Spanish companies and certain other Spanish-based assets.

What Is Spanish Inheritance and Gift Tax (ISD)?

At national level, the tax is primarily governed by Law 29/1987 on Inheritance and Gift Tax and by its implementing regulations, while Spain’s Autonomous Communities may introduce their own reductions, tax credits and other relevant rules.

• Inheritance (mortis causa succession). In this case, the transfer may include assets and rights of the deceased, with deductible debts and charges considered to determine the net value of the inheritance.
• Gift (inter vivos donation). 

Key differences between Spanish, UK and US inheritance tax systems

Spain applies a beneficiary-based system. This means that each heir or recipient is taxed individually on the value they receive.

This differs from the UK model, where Inheritance Tax is generally charged on the estate before distribution. It also differs from the US federal estate tax system, which taxes the estate rather than each beneficiary.

Another important distinction is that Spain does not have a national tax-free threshold like the UK nil-rate band. There is no general nationwide exemption below a fixed amount.

Instead, tax is calculated individually based on:

• The value of the assets received.
• The relationship between the deceased and the heir.
• The heir’s pre-existing wealth.
• The regional tax rules that apply.

As a result, two beneficiaries inheriting the same amount may pay very different tax depending on their relationship and the Autonomous Community involved.

Which Assets Are Taxable in Spain for Foreigners?

For non-residents, Spanish Inheritance and Gift Tax applies to assets located in Spain. The residence of the heir or donor is not decisive. What matters is the location of the asset.

The following assets typically fall within the scope of Spanish tax.

Properties located in Spain

Real estate situated in Spain is always subject to Spanish Inheritance or Gift Tax. This includes houses, apartments, commercial premises and land. Even if both the deceased and the heir live abroad, Spanish tax applies if the property is in Spain.

This is the most common situation affecting UK expats and other foreign investors.

Spanish bank accounts

Funds held in Spanish bank accounts are considered Spanish-situated assets. Therefore, inherited or donated balances in Spanish accounts are taxable in Spain.

Shares in Spanish companies

Shares or participations in Spanish companies are also regarded as Spanish assets. If a non-resident inherits shares in a Spanish entity, Spanish Inheritance Tax may apply. The same principle applies to gifts of corporate participations.

Life insurance policies

Life insurance proceeds may be subject to Spanish Inheritance and Gift Tax when the policyholder is different from the beneficiary. The applicable tax treatment will depend on the circumstances of the case and the relevant connecting factor under Spanish law.

Gifts of money or property located in Spain

Spanish Gift Tax applies when money or assets located in Spain are transferred without consideration. For example, a cash gift from a Spanish bank account to a non-resident child may still trigger Spanish Gift Tax.

Spanish Inheritance Tax Rates for Non-Residents (2026)

Spanish Inheritance Tax is progressive. Under national law, tax rates range from approximately 7.65% to 34%, depending on the taxable base. However, focusing only on the national scale can be misleading.

Spain operates a decentralised system. Each Autonomous Community has legislative powers to modify reductions, allowances, tax rates and final tax credits. As a result, the effective tax burden may vary significantly from one region to another.

For non-residents, this is particularly important. The applicable regional rules depend on the relevant connecting factor under Spanish law, which may be the location of the asset, the deceased’s habitual residence or the donee’s habitual residence, depending on the type of transfer.

The map below illustrates how regional differences affect inheritance taxation across Spain in 2026.

For a detailed breakdown by region, see our full guide on Inheritance and Gift Tax by Autonomous Community.

Spanish Inheritance Tax by Region: Allowances and Tax Benefits

The Autonomous Communities in Spain apply different reductions, tax scales, multipliers and tax credits under the Spanish Inheritance and Gift Tax (ISD). As a result, the final tax burden may vary significantly depending on the region. Some regions grant almost full relief for close relatives, while others impose a materially higher effective tax charge.

Example: How Much Inheritance Tax Does a Non-Resident Pay in Spain?

To understand how Spanish Inheritance Tax applies to non-residents, consider the following case.

A father owned a property in Spain and passes away. His adult son lives in the UK and is not tax resident in Spain. He inherits a Spanish property valued at €300,000. He has no disability and no relevant pre-existing wealth.

Even though the heir lives abroad, Spanish Inheritance Tax still applies. Spain taxes assets located in Spain, regardless of where the beneficiary resides.

The final tax liability depends on the Autonomous Community where the property is located. Regional rules apply to non-residents in the same way they apply to residents.

Applying the 2026 regional framework:

• Community of Madrid. The heir would generally benefit from a 99% tax reduction for close relatives (Group II). In practice, he would pay approximately 1% of the calculated tax liability, provided all regional requirements are met.
• Andalusia. The outcome would be like Madrid in most close-family cases, due to strong regional reductions.
• Catalonia. There is no general 99% reduction. The final tax due could range between €15,000 and €25,000, depending on the exact calculation and personal circumstances.
• Valencian Community. Under the current 2026 framework, close relatives may benefit from very significant tax relief, potentially bringing the effective tax burden close to that of Madrid or Andalusia, depending on the exact circumstances and compliance with the applicable requirements.

This example shows a key point for foreigners: Spain does not have a single national inheritance tax system. The effective tax burden depends largely on the region where the Spanish asset is located.

Spanish Gift Tax for Non-Residents (ISD Donations)

Spanish Gift Tax forms part of the same legal framework as Inheritance Tax. It applies when assets are transferred free of charge during the lifetime of the donor.

For non-residents, the key principle remains the same. Spain taxes assets located in Spain, regardless of where the donor or recipient lives.

Gift of money

A cash gift may be subject to Spanish Gift Tax if the funds are located in Spain at the time of transfer.

For example, if money is transferred from a Spanish bank account to a non-resident child, Spanish Gift Tax may apply.

The tax must generally be self-assessed within 30 working days from the date of the gift. The applicable rules depend on the Autonomous Community connected to the asset.

Gift of property

If a non-resident receives real estate located in Spain as a gift, Spanish Gift Tax applies automatically.

The taxable base is generally determined by the value of the transferred asset under Spanish tax rules. In the case of real estate, the taxable base is generally the higher of the declared value and the cadastral reference value applicable on the accrual date.

However, unlike some inheritance scenarios, gift tax reductions may require strict formal conditions, including execution before a Spanish notary.

Gift between parents and children (example)

Consider the following example.

A father transfers €100,000 from his Spanish bank account to his adult daughter who lives in the UK. The transfer is formalised in a public deed before a Spanish notary, and the origin of the funds and the payment trail should be properly evidenced.

If the applicable region grants a 99% reduction for gifts between parents and children, the effective tax burden may be minimal.

However, if the formal requirements are not met, or if the region does not provide strong reductions, the tax cost may increase substantially.

This illustrates an important point for non-residents. Proper structuring and regional analysis are essential before making lifetime transfers in Spain.

Double Taxation Treaties: Do They Cover Inheritance Tax?

Many foreigners assume that a tax treaty automatically prevents Spain from taxing inherited assets. This is not always correct.

Inheritance and gift taxes are not covered by most of Spain’s double taxation treaties.

UK treaty DOES NOT cover inheritance tax since 2015.

Since 2015, there is no double taxation treaty between Spain and the UK covering inheritance tax.

This means that Spain retains full taxing rights over assets located in Spain, particularly real estate.

UK residents may be able to claim relief under UK domestic law. However, the treaty itself does not eliminate Spanish tax.

US: depends on foreign tax credit mechanism.

Spain does not have a specific inheritance tax treaty with the United States.

In many cases, US taxpayers rely on the foreign tax credit mechanism under US federal tax law. This may allow a credit for Spanish tax paid, subject to limitations and technical requirements.

However, the interaction between Spanish ISD and US estate tax rules can be complex. Professional advice is strongly recommended in cross-border situations.

Filing Deadlines and Required Forms

When inheriting assets or receiving a gift in Spain, filing deadlines are strict. Missing them may result in surcharges, statutory interest and penalties.

Deadlines differ depending on whether the transfer occurs upon death or during lifetime.

6 months for inheritance

In cases of mortis causa succession, the general deadline to file Spanish Inheritance Tax is six months from the date of death.

The tax must be self-assessed before the competent Autonomous Community. Late filing triggers surcharges and interest.

Extension possible (other 6 months)

Spanish law allows a six-month extension of the filing deadline. The extension must be requested within the first five months following the date of death.

However, the extension only affects the filing deadline and statutory late-payment interest may accrue during the extended period.

30 working days for gifts

For inter vivos gifts, the deadline is significantly shorter. Spanish Gift Tax must be filed within 30 working days from the date of the gift.

This shorter deadline often surprises non-residents, particularly in cases of cash transfers from Spanish bank accounts.

Forms 650 and 651

Spanish Inheritance and Gift Tax is filed using official forms:

• Form 650 (or the relevant regional equivalent form) for inheritance.
• Form 651 (or the relevant regional equivalent form) for gifts.

Both forms must be submitted to the Autonomous Community with taxing authority over the asset.

For non-residents, identifying the correct region is essential, as regional rules determine the final tax burden.

Common Mistakes Expats Make with Spanish Inheritance Tax

The Spanish Inheritance and Gift Tax (ISD) may appear straightforward in theory. However, in practice, mistakes are frequent and often increase the overall tax cost. The most common errors include:

• Assuming Spain applies a UK-style system. Spain does not follow the UK inheritance tax model. ISD is levied on the beneficiary, not on the estate, and regional rules play a decisive role.
• Missing the six-month filing deadline. In inheritance cases, the general deadline is six months from the date of death, extendable to twelve months upon request. For gifts, the deadline is only 30 working days. Late filing triggers surcharges and interest.
• Failing to appoint a tax representative when required. Non-residents inheriting assets located in Spain may need to appoint a Spanish tax representative. Overlooking this obligation can delay the filing process.
• Underestimating regional differences. Each Autonomous Community applies its own reductions and allowances. Misidentifying the competent region or ignoring recent legislative changes can significantly affect the final tax liability.
• Incorrect valuation of assets. The taxable base depends on the value of the transferred assets under Spanish tax rules. In the case of real estate, the cadastral reference value may be decisive for determining the minimum taxable base.
• Believing that a double taxation treaty cancels the tax. Tax treaties do not automatically eliminate Spanish ISD. In many cases, Spain retains taxing rights over assets located in Spain, particularly real estate.
• Failing to apply regional reductions correctly. This often occurs when the applicable regional regulations are not properly analysed.
• Not filing gift tax on cash transfers. A cash gift is subject to Spanish Gift Tax and must be declared within 30 working days, generally using Form 651 or the relevant regional equivalent.
• Confusing a gift with a corporate transaction. Poorly structured transactions may unintentionally trigger Gift Tax instead of qualifying as a corporate reorganisation.

When Do You Need a Tax Representative in Spain?

Non-residents inheriting or receiving gifts in Spain may be required to appoint a Spanish tax representative.

Under Spanish tax law, non-resident taxpayers must appoint a representative in certain situations, particularly when dealing with the Spanish Tax Agency and regional tax authorities.

In practice, a tax representative is often necessary when:

• The heir or beneficiary has no Spanish tax identification number at the time of filing.
• The taxpayer resides outside the European Union.
• The tax authorities require a contact address in Spain for notifications.
• The case involves complex regional reductions or valuation issues.

For many non-residents, appointing a representative is not only a legal safeguard but also a practical necessity. Spanish Inheritance and Gift Tax filings require interaction with regional authorities, submission of documentation in Spanish and compliance with formal requirements.

Failing to appoint a representative when required may delay the filing process and complicate communication with the authorities.

In cross-border cases, early coordination between local advisers and a Spanish tax representative is strongly recommended.
