Inheritance Tax in Spain: What UK Families Need to Know

If you’re a UK family with property or assets in Spain, understanding Spanish inheritance tax regulations is not optional — it’s essential. Spain operates a completely different inheritance tax system to the UK, and getting it wrong can mean paying tax twice on the same assets, facing penalties, or leaving your beneficiaries with an unexpected and significant bill.

At MP Estate Planning, we help UK families protect their assets — both here and abroad. This guide walks you through how Spanish inheritance tax works, where it clashes with UK Inheritance Tax (IHT), and the practical steps you can take to plan effectively. As Mike Pugh often says: “Plan, don’t panic.”

Key Takeaways

• Spanish inheritance tax is paid by the beneficiary, not the estate — the opposite of how UK IHT works.
• Tax rates and allowances vary significantly between Spain’s autonomous communities.
• There is no specific UK-Spain double taxation treaty covering inheritance tax, creating a real risk of being taxed in both countries.
• Spanish inheritance tax regulations interact with UK IHT in complex ways that require specialist cross-border advice.
• Proper estate planning — including lifetime trusts, Spanish wills, and professional guidance — can significantly reduce your family’s overall tax exposure.

Understanding Inheritance Tax in Spain

If you own a holiday home on the Costa del Sol, a rental apartment in Barcelona, or even a Spanish bank account, your beneficiaries could face a Spanish tax bill when you die. Understanding how inheritance tax in Spain works — and how it differs from UK IHT — is the starting point for any sensible cross-border estate plan.

Definition and Importance

Inheritance tax in Spain is known as impuesto de sucesiones y donaciones (ISD). The most important thing to grasp is this: in Spain, the tax is levied on each individual beneficiary, not on the estate as a whole. This is the exact opposite of UK IHT, where the estate pays the tax before anything is distributed.

This distinction matters enormously. It means that different beneficiaries inheriting from the same person can face different tax rates — depending on their relationship to the deceased, the value of what they receive, their pre-existing wealth, and critically, which of Spain’s autonomous communities the assets are located in. Tax rates and allowances can vary dramatically from one region to another.

For UK families, understanding these rules is not just about tax efficiency — it’s about compliance. Failure to file and pay Spanish inheritance tax within the required deadlines can result in penalties, surcharges, and interest. HMRC won’t remind you about your Spanish tax obligations — that’s on you and your advisors to manage.

Key Facts about Inheritance Tax

Here are the key facts about inheritance tax in Spain that every UK family with Spanish assets should know:

• Inheritance tax is paid by each individual beneficiary, not by the estate — each beneficiary files their own return.
• Tax rates, allowances, and exemptions vary significantly between Spain’s 17 autonomous communities.
• The tax is calculated based on the value of assets received, the beneficiary’s relationship to the deceased, and the beneficiary’s pre-existing wealth (which can push them into a higher tax bracket).
• Close relatives — spouses, children, and grandchildren (Group I and II beneficiaries) — typically receive more generous allowances and lower rates than more distant relatives or unrelated individuals (Groups III and IV).

To illustrate the regional variations in inheritance tax, consider the following table, which compares the approximate tax treatment in different autonomous communities:

This table highlights how dramatically tax treatment can differ depending on where the assets are located. A property in Madrid may attract a very different tax bill from an identical property in Valencia — even for the same beneficiary. This is why generic advice is dangerous, and region-specific guidance is essential.

Who is Liable for Inheritance Tax?

One of the most common sources of confusion for UK families is understanding who actually has to pay inheritance tax in Spain — and when. The rules are different from the UK system, and getting the answer wrong can mean paying more tax than necessary, or worse, failing to pay at all and facing penalties.

Residents vs Non-Residents

The distinction between residents and non-residents is fundamental to determining your Spanish inheritance tax liability.

Spanish tax residents (those who spend more than 183 days per year in Spain or have their main economic interests there) are subject to Spanish inheritance tax on their worldwide inherited assets. This means that if you’re a UK national who has retired to Spain and become tax resident there, an inheritance from your UK-based parent — including UK property and savings — could be subject to Spanish inheritance tax.

Non-residents (which includes most UK-based beneficiaries) are only liable for Spanish inheritance tax on assets physically located in Spain. So if your late parent owned a villa in Marbella but you live and work in Birmingham, you’ll pay Spanish inheritance tax only on the Spanish property — not on any UK assets.

Following a landmark ruling by the Court of Justice of the European Union and subsequent Spanish legislative changes, EU and EEA non-residents can now apply the more favourable regional tax rules of the autonomous community where the Spanish assets are located. For UK residents post-Brexit, the position is more nuanced — Spain extended similar treatment to non-EU residents following further case law and legislative updates, but the specifics can change, and it is essential to verify the current position with a Spanish succession specialist at the time of any inheritance.

Situations That Trigger Tax Liability

Several situations can trigger a Spanish inheritance tax liability for UK families. The most common include:

• Inheriting property or other assets located in Spain — this is the most frequent trigger for UK families.
• Receiving an inheritance as a beneficiary who is tax resident in Spain, regardless of where the assets are located.
• Receiving lifetime gifts of Spanish assets (gift tax and inheritance tax fall under the same Spanish legislation).

The Spanish inheritance tax rates are further complicated by multiplier coefficients that increase the tax based on the beneficiary’s pre-existing wealth and their relationship to the deceased. A distant relative who is already wealthy could face a multiplier of up to 2.4 times the base tax — dramatically increasing the bill.

For UK families, the critical point is this: you may owe tax in both countries on the same assets. Spain will tax the beneficiary on Spanish assets. HMRC will include those same Spanish assets in the deceased’s UK estate for IHT purposes (because UK IHT applies to the worldwide estate of anyone who is UK-domiciled). Without careful planning, this means double taxation — and as we’ll discuss later, there is no specific UK-Spain treaty to prevent it for inheritance tax.

Rates and Allowances for Inheritance Tax

Understanding the specific rates and allowances for Spanish inheritance tax is essential for effective cross-border estate planning. The system is more complex than UK IHT, with multiple variables affecting the final bill.

Tax Rates Overview

The base inheritance and gift tax rates in Spain at the state level range from 7.65% to 34%, applied on a progressive scale based on the value of the inheritance received. However, this base rate is only the starting point. The final tax payable is calculated by applying multiplier coefficients based on the beneficiary’s pre-existing wealth and their relationship to the deceased.

Close relatives (Group I: children under 21; Group II: spouse, children over 21, parents, grandchildren, grandparents) benefit from the most favourable treatment. More distant relatives (Group III: siblings, aunts, uncles, nieces, nephews) and unrelated individuals (Group IV) face significantly higher effective rates due to less generous allowances and higher multipliers.

Crucially, each autonomous community can — and does — modify these rates. Some regions, such as Madrid and Andalusia, have introduced near-total exemptions for close relatives, meaning that a spouse or child inheriting property in Madrid may pay little or no Spanish inheritance tax. Other regions remain much less generous. This makes the location of the asset one of the most important factors in determining the tax bill.

Allowable Deductions and Exemptions

When calculating Spanish inheritance tax, certain allowable deductions and exemptions can substantially reduce the amount payable. At the state level, personal allowances range from approximately €15,957 for Group I and II beneficiaries to just €7,993 for Group III, with no automatic allowance for Group IV. Children under 21 receive an additional allowance increasing with each year under 21.

Many autonomous communities have increased these allowances significantly — in some cases to €1,000,000 or more for close relatives, effectively eliminating the tax for most family inheritances in those regions.

Other deductions may apply for the family home (typically a 95% reduction in value for close relatives, subject to conditions including a minimum holding period), family businesses, and assets of disabled beneficiaries. Understanding which deductions apply in your specific region is key to claiming inheritance tax relief in Spain.

For guidance on how UK IHT and capital gains tax interact with inherited property — including Spanish property reported to HMRC — see our detailed guide on inheritance tax and capital gains tax on inherited property. Effective planning across both jurisdictions can make a significant difference in the overall tax liability your family faces.

Differences Between UK and Spanish Inheritance Tax

The UK and Spanish inheritance tax systems are fundamentally different in structure. The UK taxes the estate (the deceased person’s assets as a whole, before distribution). Spain taxes each individual beneficiary on what they personally receive. This structural difference creates real complexity — and real risk of double taxation — for UK families with Spanish assets.

Rates Comparison

The headline rates differ significantly between the two systems:

• In the UK, IHT is charged at a flat rate of 40% on the taxable estate above the nil rate band (NRB) of £325,000 per person — a threshold that has been frozen since 2009 and is confirmed frozen until at least April 2031. A married couple can combine their unused NRBs for up to £650,000. The Residence Nil Rate Band (RNRB) adds a further £175,000 per person (£350,000 for a couple) when a qualifying home is passed to direct descendants — giving a combined maximum of £1,000,000 before IHT applies for a married couple. The RNRB is only available when the home passes to children, grandchildren, or step-children — not to siblings, nieces, nephews, or friends. A reduced rate of 36% applies if 10% or more of the net estate is left to charity.
• In Spain, the base rates range from 7.65% to 34% on a progressive scale, but multiplier coefficients can push the effective rate higher. However, many autonomous communities have introduced generous exemptions for close relatives — in some cases reducing the effective rate to near zero.

For a UK family with a modest Spanish holiday property, the Spanish inheritance tax on that specific property may actually be lower than the UK IHT charge — particularly if the property is in a region with generous exemptions for close relatives. The real problem is that both countries may seek to tax, and you need to manage both liabilities carefully.

Rules on Gifts and Inheritance

The rules on lifetime gifts also differ between the UK and Spain. In the UK, gifts to individuals are treated as Potentially Exempt Transfers (PETs). If the donor survives seven years after making the gift, it falls completely outside the estate for IHT purposes. If the donor dies within seven years, the gift uses up available NRB first, and any excess is taxed at 40%. Taper relief can reduce the tax — not the value of the gift — on gifts made between three and seven years before death, but only where the cumulative value of gifts exceeds the NRB of £325,000. There are also annual exemptions: £3,000 per tax year (with one year carry-forward), £250 small gifts per recipient, and wedding gifts of up to £5,000 from a parent.

It’s important to note that PETs apply to gifts made directly to individuals. Transfers into a discretionary trust are not PETs — they are Chargeable Lifetime Transfers (CLTs), subject to an immediate 20% charge on any value exceeding the available NRB at the time of transfer. For most families transferring a home worth under £325,000 (or £650,000 across two trusts for a married couple), the entry charge is zero.

In Spain, gifts are subject to gift tax under the same legislation as inheritance tax (ISD), and the tax is paid by the recipient. Gift tax rates mirror the inheritance tax structure, with the same regional variations applying. Some regions offer favourable treatment for gifts between close relatives — particularly gifts of money for a first home purchase — but others do not. There is no equivalent of the UK’s seven-year rule in Spain; the gift is taxed at the point it is made.

It is essential for UK families with assets in Spain to take advice from professionals who understand both tax systems, as the interaction between UK IHT and Spanish ISD is where the most costly mistakes are made.

Consider a practical example: a UK-domiciled parent dies owning a villa in Andalusia worth €300,000 and a UK estate worth £500,000. HMRC will include the Spanish villa in the worldwide estate for UK IHT purposes. The beneficiary will also need to file a Spanish inheritance tax return on the villa. Without planning, the family could face tax bills in both countries on the same asset.

Understanding these differences is crucial for effective estate planning and ensuring compliance with both UK and Spanish tax laws. We strongly recommend working with a solicitor or specialist advisor who has genuine expertise in both UK IHT and Spanish succession tax — the law, like medicine, is broad, and you wouldn’t want your GP doing surgery.

The Process of Paying Inheritance Tax in Spain

Paying inheritance tax in Spain involves a specific process with strict deadlines that UK beneficiaries must follow carefully. Missing a step or a deadline can result in surcharges of up to 20% plus interest — an entirely avoidable cost with proper planning.

Filing Your Tax Return

To file a Spanish inheritance tax return, beneficiaries must first obtain a NIE (Número de Identificación de Extranjero) — a Spanish tax identification number — if they don’t already have one. They will then need to complete the necessary forms, typically Modelo 650 (the inheritance tax self-assessment form) and any additional forms required by the specific autonomous community where the assets are located.

The documentation required typically includes:

• Certified death certificate of the deceased (with apostille and sworn translation if issued outside Spain)
• The deceased’s last will — or, if there is no Spanish will, a declaration of heirs and the UK Grant of Probate or Letters of Administration
• Professional valuation of the assets inherited (property, bank accounts, investments)
• Details of any debts or liabilities attached to the estate

The filing process can be complex, particularly for non-residents who may not be familiar with Spanish administrative procedures. Appointing a Spanish fiscal representative or working with a solicitor experienced in cross-border succession matters is strongly advisable. In Spain, the filing is typically handled by a gestor (administrative agent) or abogado (lawyer) on the beneficiary’s behalf.

Payment Deadlines

Beneficiaries must file their tax return and pay the inheritance tax within six months from the date of the deceased’s death. It is possible to request a six-month extension from the Spanish tax authorities, but this request must be made within the first five months of the initial deadline — not after it has expired. Late filing without an approved extension triggers automatic surcharges.

Here’s a summary of the key deadlines:

Understanding and adhering to these deadlines is crucial to avoid additional costs. Bear in mind that you may also need to obtain a UK Grant of Probate before you can deal with the Spanish assets — and the UK probate process itself typically takes several months (currently around 3–12 months for the full process, longer where property sales are involved). Starting both processes simultaneously is essential to stay within the Spanish deadline.

Navigating Spanish Inheritance Law

Spanish inheritance law differs significantly from the English and Welsh system, and navigating it properly requires understanding concepts that simply don’t exist in UK law. For UK families with Spanish assets, getting this right is the difference between a smooth succession and a costly legal tangle.

Legal Obligations for Executors

Spain does not have a direct equivalent of the English executor or personal representative system. Instead, the process is typically handled through a Spanish notary (notario), who oversees the signing of the deed of inheritance (escritura de aceptación de herencia). The key obligations include:

• Identifying and valuing all Spanish assets of the deceased.
• Paying any debts, charges, and taxes owed in Spain — including the inheritance tax.
• Executing the transfer of assets to beneficiaries in accordance with the will or, if there is no will, under the applicable rules of intestacy.

If the deceased had a UK will covering Spanish assets (rather than a separate Spanish will), the process becomes more complex. The UK Grant of Probate or Letters of Administration will need to be apostilled, translated by a sworn translator, and presented to the Spanish notary. This can add weeks or months to the timeline — another reason why having a separate Spanish will is so important.

Importance of a Will in Spain

Having a separate Spanish will to cover your Spanish assets is one of the single most effective steps you can take to simplify the inheritance process for your family. A Spanish will — drawn up before a Spanish notary and registered with the Central Registry of Last Wills (Registro General de Actos de Última Voluntad) — avoids the need to apostille and translate a UK Grant of Probate, which significantly speeds up the process and reduces costs.

Key benefits of having a separate Spanish will include:

1. Your Spanish assets can be dealt with quickly and directly through a Spanish notary, without waiting for UK probate to complete.
2. It reduces the administrative burden and legal costs for your beneficiaries.
3. It minimises the risk of conflicts arising from the interaction between UK and Spanish succession laws.

One critical consideration: Spain operates forced heirship rules (known as legítima), which reserve a proportion of the estate for certain heirs — typically two-thirds for children. However, under EU Succession Regulation 650/2012 (commonly known as “Brussels IV”), UK nationals can include a clause in their Spanish will electing for English law to govern the succession of their entire estate, including Spanish assets. This allows you to override Spanish forced heirship rules and distribute your assets according to your wishes. This election should be made explicitly in your Spanish will on the advice of a qualified cross-border succession specialist.

We strongly recommend that anyone with assets in Spain considers drafting a separate Spanish will, and ensures it does not inadvertently revoke their UK will. The two wills should be carefully coordinated so that each covers only the relevant jurisdiction’s assets.

Common Mistakes with Inheritance Tax

UK families inheriting assets in Spain frequently make avoidable mistakes that can cost thousands of pounds — or euros — in unnecessary tax, penalties, and professional fees. Here are the most common errors we see, and how to avoid them.

Misunderstanding Liability

The single biggest mistake is assuming that because you’ve paid UK IHT on an asset, you don’t also owe Spanish inheritance tax on it — or vice versa. The two systems operate independently. HMRC will include Spanish assets in the deceased’s worldwide estate for UK IHT purposes (provided the deceased was UK-domiciled). Spain will tax the beneficiary on what they receive. Both countries can — and will — seek to tax the same assets.

• Non-resident UK beneficiaries are liable for Spanish inheritance tax on Spanish assets, even though they live in the UK and have never set foot in a Spanish tax office.
• If a UK-domiciled person dies owning a Spanish property worth €400,000 and a UK estate worth £600,000, the total worldwide estate for UK IHT purposes includes both — potentially pushing the estate well above the NRB and into 40% IHT territory, on top of the Spanish tax.

Ignoring Tax Deadlines

The six-month Spanish filing deadline catches many UK families off guard. In the UK, while IHT is technically due six months after the end of the month of death, the probate process itself can take considerably longer and there is a well-established system for handling this. In Spain, the six-month deadline is strict — miss it without an approved extension and surcharges apply automatically.

Key deadlines to manage:

• File the Spanish inheritance tax return (Modelo 650) within six months of the date of death.
• Request any extension within the first five months — not the sixth.
• Start the UK probate process immediately, as you may need the Grant of Probate to deal with Spanish assets if there is no separate Spanish will.

To illustrate the consequences:

By being aware of these common mistakes and acting quickly, UK families can avoid unnecessary costs and ensure compliance with both UK and Spanish tax obligations.

Dual Taxation Treaties and Inheritance

Understanding the dual taxation treaty position between the UK and Spain is arguably the most important piece of the cross-border estate planning puzzle — and unfortunately, the answer is not what most people hope to hear.

Overview of UK-Spain Tax Treaties

The UK and Spain do have a double taxation agreement (DTA) — but it covers only income tax and capital gains tax, not inheritance tax. This is a critical distinction that catches many UK families unaware.

Key points about the UK-Spain tax treaty:

• It provides relief from double taxation on income and capital gains only.
• It establishes clear rules for determining tax residency for income tax purposes.
• It facilitates the exchange of information between HMRC and the Spanish tax authorities (Agencia Tributaria).

How Treaties Affect Inheritance Tax

Because the UK-Spain DTA does not cover inheritance tax, there is no automatic mechanism to prevent the same assets being taxed twice — once by HMRC under UK IHT, and once by the Spanish tax authorities under ISD. This is not a theoretical risk; it happens routinely to UK families with Spanish property.

The practical implications are significant:

1. Beneficiaries may face inheritance tax liabilities in both the UK and Spain on the same Spanish assets.
2. There is no treaty-based right to offset one country’s tax against the other’s for inheritance tax purposes.
3. However, UK law does provide unilateral relief: HMRC allows a credit for overseas tax paid on the same assets under its double taxation relief provisions. This means that if you pay Spanish inheritance tax on a Spanish property, you can usually offset that against the UK IHT liability on the same property — but the relief is limited to the lower of the two tax charges. You won’t get a refund if the Spanish tax exceeds the UK IHT attributable to that asset.

The absence of a specific inheritance tax treaty between the UK and Spain means that families must be proactive in managing their tax obligations in both countries. Relying on the assumption that “they can’t tax it twice” is one of the most expensive mistakes we see.

To mitigate the effects of double taxation on inheritance, it’s essential for families to take specialist cross-border advice. Strategies may include structuring ownership of Spanish assets, making a separate Spanish will with an English law election, and using lifetime trusts for UK assets to reduce the overall UK estate value. By understanding the limitations of the dual taxation treaty position and planning accordingly, UK families can significantly reduce their total cross-border tax exposure.

Steps to Take When Inheriting Property in Spain

Inheriting property in Spain as a UK-based beneficiary involves a specific sequence of steps. Getting the order right — and acting quickly — is crucial to meeting Spanish deadlines and minimising costs.

Assessing the Value of the Estate

The first step when inheriting property in Spain is to obtain a professional valuation of all Spanish assets. This is important for two reasons: it determines the Spanish inheritance tax liability, and HMRC will also need to know the value of Spanish assets for the UK IHT return.

Key factors to consider when assessing the estate’s value include:

• The current market value of any Spanish property — a formal valuation from a qualified Spanish surveyor (tasador) is advisable, as the Spanish tax authorities may challenge undervaluations based on their own reference values (valor de referencia catastral)
• Any outstanding Spanish mortgage or charge on the property — debts reduce the taxable value
• The value of Spanish bank accounts, investments, vehicles, and other assets

It’s worth noting that the Spanish tax authorities increasingly cross-reference declared values against their cadastral reference values. Declaring a value significantly below the reference value can trigger an inspection or reassessment, so professional guidance on the valuation is essential.

Legal Considerations for Property Inheritance

Understanding the legal process is vital when inheriting property in Spain. The key steps typically include:

1. Obtain the necessary documents: Death certificate, the deceased’s Spanish will (from the Central Registry of Last Wills), or if there is no Spanish will, the UK Grant of Probate apostilled and translated.

2. Attend the Spanish notary: All beneficiaries (or their legal representatives under a notarised power of attorney) must sign the deed of inheritance before a Spanish notary.

3. Pay Spanish inheritance tax: This must be paid before the property can be transferred into the beneficiaries’ names at the Land Registry.

4. Register the transfer: Once tax is paid, the property is registered in the beneficiaries’ names at the Spanish Property Registry (Registro de la Propiedad). The plusvalía municipal (local land value increase tax) must also be paid to the local council within 30 days of death.

Forced heirship rules are an important consideration under Spanish law. Two-thirds of the estate is normally reserved for the deceased’s children. However, as noted above, UK nationals can elect for English law to govern the succession of their estate under the Brussels IV Regulation — meaning forced heirship can be avoided with proper planning.

By acting quickly, obtaining proper valuations, and working with professionals in both the UK and Spain, you can navigate the process of inheriting Spanish property as efficiently as possible. Starting late is the single biggest cause of unnecessary cost and stress.

The Role of Professional Advisors

When dealing with cross-border inheritance involving both the UK and Spain, generic advice is not sufficient. You need professionals with specific expertise in both UK IHT and Spanish succession tax — and ideally, experience in how the two systems interact.

Importance of Professional Guidance

Professional advisors with cross-border expertise can make the difference between an efficient, tax-optimised succession and one that leaves your family paying significantly more than necessary. The benefits of taking proper advice include:

• Accurate assessment of both UK IHT and Spanish inheritance tax liabilities — not just one or the other
• Identification of available reliefs, including HMRC’s unilateral double taxation relief and region-specific Spanish exemptions
• Structuring advice — such as whether to hold Spanish property personally, through a Spanish company (SL), or through a UK trust — each option has different tax consequences in both jurisdictions, and a trust in particular must be carefully considered because Spain does not recognise trusts in the same way as England and Wales
• Coordination of UK and Spanish wills to ensure they work together without one accidentally revoking the other
• Assistance with the practical process: NIE applications, Spanish tax filings, notary appointments, and Land Registry transfers

At MP Estate Planning, we specialise in UK-side estate protection — including lifetime trusts that can reduce UK IHT exposure on your overall estate, even if the Spanish assets themselves require separate handling. Our Estate Pro AI tool provides a comprehensive 13-point threat analysis of your estate, identifying vulnerabilities you may not have considered. Trusts are not just for the rich — they’re for the smart.

Choosing the Right Advisor

Selecting the right advisor is crucial. For cross-border UK-Spain inheritance matters, you typically need a team rather than a single professional — a UK estate planning specialist and a Spanish abogado or asesor fiscal who work together. Here are the key criteria to evaluate:

Be wary of advisors who claim expertise in “international tax” but have no specific experience with UK-Spain succession matters. The interaction between these two systems is highly specific, and generic international tax knowledge is not enough.

Case Studies: Inheritance Tax in Action

Understanding how Spanish inheritance tax works in practice is far more useful than learning the theory in isolation. These examples illustrate the types of issues UK families commonly face — and the lessons they learned.

Examples from Real Families

Consider a family where the parents — both UK-domiciled and UK-resident — owned a holiday apartment in Andalusia worth approximately €250,000, alongside a UK estate (home, savings, pensions) worth around £600,000. When the father died, the family assumed that because they’d paid UK IHT on his worldwide estate (which included the Spanish property), they had no further obligation. They were wrong.

The two adult children, as beneficiaries of the Spanish property, were each independently liable for Spanish inheritance tax on their share. Because they failed to file within six months, they also faced surcharges. The total Spanish tax bill — which should have been modest given Andalusia’s generous exemptions for close relatives — was significantly increased by the late filing penalties.

Key factors that determined their Spanish tax liability included:

• The value of the Spanish property at the date of death — the Spanish tax authorities applied their own reference value, which was higher than the family’s estimate.
• The relationship between the deceased and the beneficiaries — as children (Group II), they qualified for Andalusia’s regional exemptions, but these had to be properly claimed.
• The beneficiaries’ pre-existing wealth — one child had significant savings, which increased the multiplier coefficient applied to their share.

Lessons Learned from Different Scenarios

Across the cases we’ve seen, several recurring lessons emerge:

In another scenario, a retired couple who split their time between the UK and Alicante had taken proactive steps. They made a separate Spanish will with an English law election, registered it with the Central Registry of Last Wills, and ensured their UK will explicitly excluded Spanish assets. When the husband died, the Spanish succession process was completed within four months — well within the six-month deadline — and the widow was able to apply regional allowances that effectively eliminated the Spanish tax on her share.

Meanwhile, on the UK side, they had placed their English family home into a Family Home Protection Trust years earlier, which meant it was protected from potential care fees and bypassed probate delays. The combination of Spanish and UK planning meant the family’s total exposure to both IHT and Spanish inheritance tax was significantly reduced.

1. Act immediately — the six-month Spanish deadline is strict, and UK probate can take months. Run both processes in parallel from day one.
2. Have a separate Spanish will — this single step avoids the most common delays and complications.
3. Take specialist advice on both sides — a UK estate planner and a Spanish succession specialist working together will almost always save you more than their combined fees.

Planning Ahead: Strategies to Reduce Inheritance Tax

Effective cross-border estate planning is not about avoiding tax — it’s about ensuring your family doesn’t pay more than the law requires. For UK families with assets in Spain, the strategies available depend on the type and value of assets, where they’re located, and how they’re owned.

Minimising Tax Liability

Several legitimate strategies can reduce the combined UK and Spanish inheritance tax burden:

On the UK side: Placing your UK family home into a lifetime trust — such as a Family Home Protection Trust — can protect it from care fees, bypass probate delays, and in some structures, begin the process of reducing your estate’s IHT exposure. Trust assets bypass probate entirely — trustees can act immediately on the settlor’s death, without waiting months for a Grant of Probate while all sole-name assets are frozen. For investment properties or buy-to-let portfolios, a Settlor Excluded Asset Protection Trust can remove the property from your estate entirely for IHT purposes (subject to surviving seven years for the initial transfer to fall outside the estate). And if you have life insurance, placing it into a Life Insurance Trust ensures the payout goes directly to your beneficiaries without the 40% IHT charge — this is typically free to set up.

On the Spanish side: Choosing to hold Spanish property in personal names (rather than through a company) is often more tax-efficient for inheritance purposes in regions with generous family exemptions. Making a separate Spanish will with an English law election under Brussels IV avoids forced heirship complications. And understanding which region-specific reliefs apply — particularly the 95% family home reduction available in many communities — can dramatically reduce the Spanish tax bill.

It’s worth putting the cost of UK-side planning into perspective. A lifetime trust typically costs from £850, depending on complexity — roughly equivalent to one or two weeks of residential care fees (currently averaging £1,100–£1,300 per week in England, and considerably more in London and the south). It’s a one-time cost that can protect your family’s wealth for up to 125 years.

Effective Strategies for Estate Planning

The most effective approach combines UK and Spanish planning into a single coordinated strategy. Key estate planning tips for UK families with Spanish assets include:

• Make two wills: A UK will covering UK assets and a Spanish will covering Spanish assets, carefully drafted so neither revokes the other.
• Consider lifetime trusts for UK assets: Reducing the value of your UK estate means less total IHT across both jurisdictions, since HMRC taxes your worldwide estate. The most common type of trust used in family estate planning is the discretionary trust, where trustees have absolute discretion over how and when to distribute assets to beneficiaries. No beneficiary has an automatic right to income or capital — which is precisely what provides the protection. These trusts can last up to 125 years under current law.
• Use available UK IHT allowances: The annual gift exemption of £3,000 (with one year carry-forward), small gifts of £250 per recipient, wedding gifts, normal expenditure out of income, and lifetime gifts to individuals (PETs) that fall outside your estate after seven years — all reduce the estate that HMRC will tax.
• Get the property valuation right: In Spain, declaring the correct value from the outset avoids costly reassessments. In the UK, accurate valuations ensure you claim the correct double taxation relief.
• Plan early: The worst time to start cross-border estate planning is after someone has died. The best time is now — while you have options, time, and the ability to make choices. As Mike Pugh says: “Not losing the family money provides the greatest peace of mind above all else.”
