Inheritance Tax in Spain: Differences Between Regions Explained

🇪🇸 Read the original in Spanish

Dealing with the loss of a loved one is one of the most difficult moments in anyone's life—a period of grief that, unfortunately, is often clouded by dense bureaucracy and a significant tax burden. In Spain, the Impuesto sobre Sucesiones y Donaciones (ISD - Inheritance and Gift Tax) generates enormous uncertainty due to the profound disparities existing between the different territories. This makes inheriting in one autonomous community practically free, while in another it can cost an absolute fortune. Understanding how this devolved tax works, knowing the legal deadlines to avoid penalties, and knowing how to optimize your tax bill according to your place of residence is essential to protect family assets and avoid unpleasant surprises with the Agencia Tributaria (Tax Agency).

The Legal Framework of Inheritance Tax in Spain

Inheritance and Gift Tax is a direct, subjective tax levied on the acquisition of assets and rights by inheritance, legacy, or any other title of succession. Its basic regulation is found in Law 29/1987, of December 18, on the Inheritance and Gift Tax, and its Regulations, approved by Royal Decree 1629/1991, of November 8. Likewise, the Código Civil (Civil Code) regulates the fundamental rules on succession, forced heirship (legítimas), and the partition of the inheritance in its Title III (Book III, Articles 657 and following).

However, the key to the massive regional disparity lies in Law 22/2009, of December 18, which regulates the financing system of the Autonomous Communities of common regime. This law devolves regulatory powers over Inheritance Tax to the autonomous communities, allowing them to regulate crucial aspects such as:

• Reductions in the taxable base (for kinship, disability, acquisition of the primary residence, or family business).
• The tax scale (the tax rates).
• Deductions and allowances (bonificaciones) on the tax liability.

This devolution of powers has created 17 different tax scenarios in Spain, in addition to the chartered regimes of the Basque Country (concierto económico) and Navarre (convenio económico), which enjoy even greater tax autonomy.

Which Autonomous Community is Competent to Liquidate the Tax?

One of the most frequent doubts, especially for foreign residents or families with members scattered across Spain, is knowing which autonomous community is responsible for collecting the tax.

The law establishes a clear and unavoidable criterion: the tax must be liquidated in the autonomous community where the deceased had their habitual residence during the last 5 years prior to death.

It does not matter where the real estate assets of the inheritance are located (for example, if the deceased resided in Madrid but you inherit a beach apartment in Alicante, the tax is liquidated under the regulations of the Community of Madrid). Nor does it matter where the heirs reside.

The Case of Non-Residents (Foreigners and Expats)

Historically, non-residents in Spain had to liquidate the tax under state regulations, which lack the allowances applied by the autonomous communities, resulting in a much higher tax bill. However, following the landmark ruling of the Court of Justice of the European Union (CJEU) of September 3, 2014, Spanish legislation was amended.

Currently, if the deceased was a non-resident in Spain but resided in the European Union or the European Economic Area (and following subsequent rulings of the Tribunal Supremo (Supreme Court), this also applies to residents in third countries such as the United Kingdom or the United States), the heirs have the right to apply the regulations of the autonomous community where the highest value of the inheritance assets is located.

The Map of Inequality: Key Differences Between Autonomous Communities

To understand the differences, it is necessary to classify heirs according to the kinship groups established by state law:

• Group I: Descendants and adoptees under 21 years of age.
• Group II: Descendants and adoptees of 21 years of age or older, spouses, ascendants, and adopters.
• Group III: Collaterals of the second and third degree (siblings, nephews/nieces, uncles/aunts), and ascendants and descendants by affinity.
• Group IV: Collaterals of the fourth degree (cousins), more distant degrees, and strangers.

Communities with Extreme Tax Allowances (Practically "Zero Cost")

For Groups I and II (children, spouses, and parents), several autonomous communities apply allowances (bonificaciones) of between 99% and 100% of the tax liability. This means that direct heirs pay almost no tax. Notable among them are:

• Community of Madrid: A 99% allowance for Groups I and II. Recently, a 25% allowance has also been approved for siblings, uncles/aunts, and nephews/nieces (Group III).
• Andalusia: Maintains a reduction of up to 1,000,000 € of the taxable base per direct heir (Group I and II), leaving the vast majority of inheritances exempt. For higher amounts, it applies a 99% allowance.
• Valencian Community: Applies a 99% allowance for Groups I and II since late 2023.
• Balearic Islands: Eliminated the tax for Groups I and II in 2023 by applying a 100% allowance.
• Canary Islands, Cantabria, Extremadura, La Rioja, and the Region of Murcia: Have allowances of 99% or 100% for direct relatives.

Communities with Moderate or Progressive Taxation

In these regions, the tax is calculated by applying kinship reductions which, although significant, may exclude medium or high estates, or require the payment of progressive amounts:

• Catalonia: Applies allowances on the tax liability inversely to the value of what is inherited. The more that is inherited, the lower the percentage of the allowance (ranging between 99% and 57% for spouses, and notably lower for children).
• Galicia: The first 400,000 € inherited by each child or ascendant is exempt from taxation. Above this figure, reduced tax rates apply.
• Castilla y León: Features a 99% allowance for Group I and II, but maintains strict limits for other scenarios.

Communities with Higher Tax Pressure

Asturias and Aragon, along with some regions that apply the state scale more strictly with almost no additional allowances (especially for inheritances from uncles/aunts to nephews/nieces or between siblings), historically sit on the side of higher tax demands, although all have gradually introduced specific reductions for low taxable bases or the transfer of the primary residence.

Practical Examples: The Impact of Tax Residence

To visualize the magnitude of these differences, we will analyze two specific scenarios with real figures.

Example 1: The Inheritance of an Only Child in Madrid vs. Asturias

Let us imagine that Juan (aged 45) inherits a net estate (after debts) valued at 800,000 € from his deceased father, which includes the father's primary residence (valued at 300,000 €) and bank accounts worth 500,000 €.

• Scenario A (Father's residence in Madrid): By applying the reduction for the acquisition of the primary residence and the 99% allowance on the tax liability, the final tax amount to be paid by Juan will be approximately 1,200 €.
• Scenario B (Father's residence in Asturias): Despite the applicable regional reductions, the progressive scale and the lack of a generalized 99% allowance for this volume of assets will mean Juan has to pay an amount that can easily exceed 45,000 €.

Example 2: Inheritance from Uncles/Aunts to Nephews/Nieces (Group III)

María passes away without children or a spouse in Andalusia and leaves her niece Sofía a flat valued at 150,000 € and 50,000 € in cash (total inheritance: 200,000 €).

Belonging to Group III (niece), the 99% allowances intended for direct relatives do not apply in most communities. After applying the minimum state reductions and the multiplying coefficients for pre-existing wealth, Sofía could face a tax bill of between 30,000 € and 50,000 € depending on the community. This occasionally forces heirs to apply for loans or even reject the inheritance due to being unable to afford the tax payment.

Practical Step-by-Step Procedures to Liquidate an Inheritance

Liquidating Inheritance Tax requires following a strict administrative process to avoid penalties. These are the steps you must take:

1. *Obtaining the Death Certificate (Certificado de Defunción): Requested from the Registro Civil* (Civil Registry) of the place of death 24 hours after it occurs.
2. *Requesting the Last Will Certificate (Certificado de Últimas Voluntades) and Life Insurance Contracts Certificate: 15 business days* must pass from the date of death. This document certifies whether the deceased made a will and before which notary.
3. Obtaining the authorized copy of the Will or Declaration of Heirs: If there is a will, it is requested from the corresponding notary's office. If there is none, a notary deed of declaration of heirs ab intestato (intestate) must be carried out.
4. Inventory of assets and debts: Gather property deeds, bank balance certificates as of the date of death, vehicle documentation, etc.
5. *Drafting the Deed of Acceptance and Partition of Inheritance (Escritura de Aceptación y Adjudicación de Herencia): Formalized before a notary (essential if there are real estate assets to be registered in the Registro de la Propiedad* (Property Registry)).
6. Filing and payment of the Inheritance Tax (Form 650): Must be self-assessed or presented for liquidation before the tax office of the competent autonomous community.
7. *Liquidation of the Municipal Capital Gains Tax (IIVTNU / Plusvalía Municipal):* If the inheritance includes urban real estate, this tax must be liquidated before the town hall where the properties are located.

Deadlines, Amounts, and Key Figures You Must Know

Compliance with deadlines is one of the most critical aspects of Spanish inheritance law:

• Filing deadline: The deadline to file and pay the Inheritance Tax is 6 months starting from the day of the deceased's passing.
• Legal extension: An additional extension of another 6 months can be requested. This request must be submitted within the first 5 months of the filing period. The granting of the extension entails the accrual of late-payment interest in favor of the Public Treasury.
• Tax statute of limitations: The Administration's right to determine the tax debt through the appropriate assessment expires after 4 years, 11 months, and 1 day (the 4-year general limitation period of Article 66 of the Ley General Tributaria (General Tax Law) plus the 6-month voluntary filing period).
• Surcharges for late filing (without prior notice): If filed late voluntarily, surcharges ranging from 1% to 15% will apply (plus late-payment interest if the delay exceeds 12 months), according to the Ley General Tributaria.

Mistakes You Must Avoid

• Letting the 6-month deadline pass: This is the most common mistake. Thinking "there is plenty of time" can completely void regional tax allowances (many communities require that the tax be filed strictly within the legal deadline as a condition to apply the 99% allowance).
• Failing to declare bank accounts of which the deceased was a co-holder: The Tax Agency will cross-reference bank data. If the deceased was a 50% co-holder with their spouse, it is understood that 50% of the balance belongs to the inheritance and must be taxed, unless it is irrefutably proven that the funds belonged exclusively to one of them.
• *Forgetting the Municipal Capital Gains Tax (Plusvalía): Many heirs liquidate the Inheritance Tax but forget to file the Plusvalía Municipal* at the corresponding town hall, which generates considerable fines and surcharges.
• *Valuing properties below the Cadastral Reference Value (Valor de Referencia de Catastro): Since January 1, 2022, the taxable base of properties is determined by the Valor de Referencia del Catastro*. Declaring below this value will trigger an automatic valuation check by the regional tax authority.

Frequently Asked Questions (FAQ)

What happens if I do not have the money to pay the Inheritance Tax?

You can request a deferral or installment payment plan from the regional tax agency. It is also possible to request that banking entities release funds from the deceased's own current accounts exclusively to pay the inheritance tax, without needing to have previously acquired the formal status of heir.

Can I reject an inheritance if the debts exceed the assets?

Yes. The Código Civil allows you to repudiate the inheritance in its entirety. Another highly recommended option is to accept the inheritance under benefit of inventory (a beneficio de inventario). In this way, the deceased's debts are paid solely and exclusively with the assets of the inheritance itself, completely protecting your current and future personal wealth.

Where are life insurance policies taxed in an inheritance?

Life insurance policies for the event of death are taxed under the Inheritance and Gift Tax, accumulating with the rest of the assets received by the beneficiary if they are also an heir. They are liquidated in the same autonomous community of residence of the deceased.

If my father resided abroad and I live in Spain, where do I pay?

If the deceased did not reside in Spain but you (the heir) do reside in Spanish territory, you are taxed by "personal obligation" (obligación personal). You must liquidate the tax in the autonomous community where you have your habitual residence, and you can apply the deductions and allowances of that community.

In Summary

• Tax jurisdiction: Inheritance Tax is always liquidated in the autonomous community where the deceased resided for the majority of the last 5 years.
• Strict deadline: You have a maximum period of 6 months from the death to liquidate the tax, extendable for another 6 months if requested on time.
• Regional gap: The differences between communities are abysmal; regions like Madrid, Andalusia, or the Valencian Community discount up to 99% or 100% for direct relatives, while others maintain high taxation.
• Reference Value: Since 2022, real estate must be declared taking the Valor de Referencia de Catastro as the minimum base to avoid penalties.
• Key planning: Knowing the applicable regulations and deadlines is vital to avoid losing regional tax benefits and to prevent late-payment surcharges.
