Navigating Inheritance Tax on Overseas Property in the UK

If you’re a UK resident, expat, or someone with property abroad, understanding how inheritance tax on overseas property works is essential for protecting your estate. The rules can be surprisingly complex — involving domicile status, double taxation agreements, and the interplay between UK and foreign tax systems — but with the right planning, you can ensure your family keeps more of what you’ve worked hard to build.

At MP Estate Planning, we specialise in helping individuals navigate these complexities, providing clear and accessible guidance on inheritance tax planning and trust-based asset protection. Our founder Mike Pugh believes that “trusts are not just for the rich — they’re for the smart,” and that principle applies just as much to overseas property as it does to your family home in England.

Key Takeaways

• If you’re UK domiciled, HMRC can charge inheritance tax (IHT) at 40% on your worldwide assets — including overseas property — above the nil rate band of £325,000.
• Your domicile status (not just your residence) determines whether overseas property falls within the UK IHT net.
• Double taxation agreements with certain countries can prevent you from being taxed twice on the same property.
• Lifetime trusts, lifetime gifting, and proper use of reliefs and exemptions can significantly reduce the IHT exposure on foreign assets.
• Professional specialist advice is essential — the law around overseas property, domicile, and IHT is one of the most complex areas of UK tax planning.

Understanding Inheritance Tax

For anyone who owns property outside the UK, understanding how inheritance tax on overseas property works is not optional — it’s essential. IHT is a tax on the estate of someone who has died, and the rules about what falls within its scope depend heavily on your domicile status and the location of your assets.

What is Inheritance Tax?

Inheritance tax (IHT) in the UK is charged at 40% on the value of the taxable estate above the nil rate band (NRB) of £325,000 per person. This NRB has been frozen since April 2009 and is confirmed frozen until at least April 2031 — meaning inflation is dragging more and more ordinary families into the IHT net every year. There is also a reduced rate of 36% if you leave at least 10% of your net estate to charity.

If you are domiciled in the UK (or deemed domiciled — more on that below), HMRC charges IHT on your worldwide assets. That includes any property you own in Spain, France, Portugal, the United States, or anywhere else in the world. If you are not UK domiciled, IHT generally only applies to your assets situated within the UK.

This is where inheritance tax for expats gets particularly complex. A UK national living abroad may still be treated as UK domiciled, meaning their overseas villa or apartment is caught by UK IHT. Conversely, a foreign national living in the UK may become “deemed domiciled” after a certain period of residence, bringing their worldwide assets into the UK IHT net too.

How is Inheritance Tax Calculated?

The calculation of IHT involves adding up the total value of the deceased’s estate — including all worldwide assets for UK-domiciled individuals — then deducting liabilities, reliefs, and exemptions. Here’s a simplified breakdown of the key components:

For non-resident inheritance tax situations, the picture is further complicated by potential tax charges in both the UK and the country where the property is located. This is where double taxation agreements become critical — without one, you could face IHT in the UK and an equivalent local tax abroad.

Understanding the inheritance tax rules for foreign assets is vital for reducing unnecessary tax. This includes being aware of the spouse exemption (transfers between UK-domiciled spouses or civil partners are generally exempt from IHT without limit), the annual gift exemption (£3,000 per tax year with one year’s carry-forward), and the potential to use irrevocable lifetime trusts to move assets outside your taxable estate over time. It’s worth emphasising that a revocable trust provides no IHT benefit whatsoever — HMRC treats the assets as still belonging to the settlor. Only an irrevocable trust, properly structured, can begin to move assets outside the estate.

Inheritance Tax on Overseas Property

For UK-domiciled individuals with overseas property, the IHT implications are significant — and often misunderstood. Let’s look at the specific rules and what they mean in practice.

What You Need to Know

If you are UK domiciled, HMRC treats your worldwide estate as subject to IHT. That includes your holiday home in the Algarve, your apartment in Marbella, or your rental property in Florida. Every asset worldwide is aggregated and taxed at 40% above the available nil rate band.

The key considerations include:

• The market value of your overseas property at the date of death — converted into pounds sterling at the exchange rate on that date.
• Any debts or liabilities secured against the property (for example, a local mortgage), which can be deducted from its value for IHT purposes.
• Whether the country where the property is located also charges its own form of inheritance or succession tax — creating a potential double taxation scenario.

Tax Implications for UK Residents

As a UK-domiciled individual, your overseas property is firmly within the UK IHT net. But you may also face a local succession tax or equivalent in the country where the property sits. France, Spain, and many other countries have their own inheritance tax systems, and the rates and rules vary enormously.

To mitigate potential double taxation, the UK has double taxation agreements (DTAs) with a number of countries — although not as many as you might expect. The UK currently has IHT-specific DTAs with only around a dozen countries, including France, the Netherlands, Italy, India, Ireland, and the United States. If there is no DTA in place, you may still be able to claim unilateral relief — essentially a credit against UK IHT for any foreign tax paid on the same asset.

Effective planning can substantially reduce the overall tax burden. Strategies range from lifetime gifting (starting the 7-year clock for potentially exempt transfers), using irrevocable lifetime trusts for investment properties, and structuring ownership to take maximum advantage of available reliefs. The important thing is to act well in advance — these are not deathbed solutions. As Mike Pugh says, “Plan, don’t panic.”

Domicile Status and its Impact

Domicile status is perhaps the single most important factor in determining the scope of your UK IHT liability. It’s a concept that catches many people out — particularly expats who assume that leaving the UK means leaving UK tax behind.

What is Domicile?

Domicile is a legal concept that refers to the country an individual considers their permanent home — the place they ultimately intend to return to. It is not the same as residence or nationality. You can be resident in Spain for twenty years and still be domiciled in the UK if HMRC determines that the UK remains your permanent home in law.

There are three types of domicile under UK law:

• Domicile of origin: Acquired at birth, typically from your father (or mother if parents were unmarried). This is the default and can be very difficult to shed.
• Domicile of choice: Acquired by settling permanently in another country with the genuine intention of making it your permanent home indefinitely. You must abandon your domicile of origin — which HMRC scrutinises very carefully.
• Deemed domicile: Under rules introduced in April 2017, you are treated as UK domiciled for IHT purposes if you have been UK resident for at least 15 of the past 20 tax years, OR if you were born in the UK with a UK domicile of origin and later become UK resident again.

HMRC looks at a wide range of factors when assessing domicile: where your family lives, where your social and economic ties are strongest, where you keep your possessions, where you intend to be buried, and — crucially — where you intend to live permanently in the future.

How Domicile Affects Inheritance Tax

Your domicile status directly determines whether your overseas property is caught by UK IHT:

• If you’re domiciled in the UK (or deemed domiciled), your worldwide assets — including all overseas property — are subject to UK IHT at 40% above the NRB.
• If you’re not domiciled in the UK and not deemed domiciled, you’re generally only subject to UK IHT on assets physically situated in the UK (such as UK property, UK bank accounts, and UK shares).
• The deemed domicile rules mean that long-term UK residents who are foreign domiciled can be brought into the worldwide IHT net after 15 out of 20 years of UK residence.

Understanding your domicile status and its implications for IHT is absolutely crucial for effective estate planning. Many expats assume they have acquired a domicile of choice abroad, only for HMRC to challenge this after death — at which point it’s too late to plan. If you own overseas property and have any connection to the UK, obtaining specialist advice on your domicile position should be a priority.

Valuing Overseas Property

Valuing overseas property accurately is a critical step in calculating your IHT liability. HMRC requires the property to be valued at its open market value on the date of death — and getting this right is essential, because both undervaluation and overvaluation can cause problems.

How to Determine Market Value

The market value is the price the property would fetch if sold on the open market at the date of death, between a willing buyer and a willing seller. In practice, this means:

• Obtaining a professional valuation from a qualified local surveyor or valuer who understands the property market in that country.
• Researching recent comparable sales in the same area — what similar properties have actually sold for, not just their asking prices.
• Taking into account the property’s condition, location, size, legal restrictions, and any sitting tenants or charges against it.

It’s worth noting that HMRC’s District Valuer can challenge any valuation they consider unreasonable, even for overseas property. Having a robust, independent professional valuation is your best defence.

Currency Fluctuations and Valuation

Currency fluctuations add another layer of complexity. HMRC requires overseas property to be valued in sterling, using the exchange rate at the date of death. This means the same property can have a significantly different IHT value depending on the exchange rate at the time.

For example, if the pound strengthens against the euro between the time you bought a French property and the date of death, the sterling value of that property falls — potentially reducing the IHT bill. Conversely, if sterling weakens, the property’s value in IHT terms increases.

There is no mechanism to choose a favourable exchange rate — HMRC uses the spot rate on the date of death. However, understanding this dynamic can be useful when planning ahead, particularly if you’re considering making lifetime gifts of overseas property or transferring it into an irrevocable lifetime trust.

Legal Framework for Overseas Inheritance Tax

Understanding the legal landscape of overseas inheritance tax is crucial for UK-domiciled individuals with foreign assets. The framework involves the interaction between UK IHT legislation and the inheritance or succession tax systems of other countries — and these don’t always align neatly.

UK vs International Tax Laws

The UK charges IHT as a tax on the estate of the deceased person, based on the worldwide assets of UK-domiciled individuals. However, many other countries operate fundamentally different systems. Some countries (such as France and Spain) charge inheritance tax on the recipient rather than the estate. Others (like Portugal) have no inheritance tax at all but may charge stamp duty on inherited property.

Key differences between UK and international tax systems include:

• Tax base: The UK taxes the estate as a whole; many European countries tax each beneficiary individually based on their share and their relationship to the deceased.
• Forced heirship rules: Many civil law countries (France, Spain, Italy) have “forced heirship” rules that override the terms of a will and require a certain proportion of the estate to pass to specific family members. England and Wales generally allow freedom of testamentary disposition (you can leave your estate to whoever you want), though this freedom is subject to the Inheritance (Provision for Family and Dependants) Act 1975, which allows certain dependants to make a claim for reasonable provision.
• Recognition of trusts: Many countries — particularly those with civil law systems — do not recognise the concept of a trust in the same way that England does. England invented trust law over 800 years ago, but holding overseas property in a UK trust can create complications in countries that don’t have an equivalent legal concept. This is one of the most important practical issues to resolve with specialist advice before placing overseas property into a trust.

Double Taxation Agreements

Double taxation agreements (DTAs) are bilateral treaties designed to prevent the same asset from being taxed in two countries. For IHT purposes, the UK has specific DTAs with only a limited number of countries — currently including France, India, Ireland, Italy, the Netherlands, Pakistan, South Africa, Sweden, Switzerland, and the United States.

Key benefits of DTAs include:

1. Establishing which country has the primary right to tax specific types of assets (immovable property is usually taxed where it’s located).
2. Providing credit relief so that tax paid in one country reduces the liability in the other.
3. Preventing the combined tax burden from exceeding what would be charged by either country alone.

For example, under the UK-France DTA, immovable property (real estate) in France is taxed according to French succession tax rules, and the UK then gives credit for the French tax paid against the UK IHT liability on the same property. This prevents genuine double taxation, though you still need to comply with reporting requirements in both countries.

What if there’s no DTA? If you own property in a country with no IHT-specific DTA with the UK (such as Spain or Portugal), you may still be able to claim unilateral relief under UK domestic law. This allows a credit against UK IHT for any foreign tax of a similar character paid on the same asset. However, the relief is not automatic — it must be claimed, and the rules can be complex.

Planning to Minimise Inheritance Tax

Minimising IHT on your overseas assets requires careful, proactive planning — ideally years before it becomes an urgent issue. As Mike Pugh says, “Plan, don’t panic.” The strategies available depend on your domicile status, the type of property, and the tax rules in the country where the property is located.

Effective Estate Planning Strategies

Effective estate planning is the cornerstone of reducing IHT liabilities. This involves reviewing your entire estate — UK and overseas — and implementing strategies tailored to your specific circumstances. Key approaches include:

• Lifetime gifting: Gifts to individuals are potentially exempt transfers (PETs) for IHT purposes. If you survive seven years after making the gift, it falls entirely outside your estate. Taper relief reduces the tax (not the value of the gift) if you die between three and seven years after making it — though taper relief only applies where the cumulative value of gifts exceeds the NRB of £325,000. However, be aware that gifting property abroad may trigger local tax charges such as capital gains tax or transfer tax in the country where the property sits. It’s also important to note that transfers into a discretionary trust are not PETs — they are chargeable lifetime transfers (CLTs), with an immediate lifetime charge of 20% on value above the available NRB.
• Using your annual exemptions: Every individual has a £3,000 annual gift exemption (with one year’s carry-forward), plus £250 small gifts per recipient per year. While these won’t cover the value of a property, they form part of a wider, disciplined gifting strategy over time.
• Maximising the spouse exemption: Transfers between spouses and civil partners are exempt from IHT without limit (provided both are UK domiciled). For couples where one spouse is non-UK domiciled, the exemption is currently capped, though the non-domiciled spouse can elect to be treated as UK domiciled for IHT purposes to access the full exemption — bearing in mind this also brings their own worldwide assets into the UK IHT net.
• Charitable legacies: Leaving at least 10% of your net estate to charity reduces the IHT rate on the remaining taxable estate from 40% to 36%.
• Regular review: Your estate plan should be reviewed whenever your circumstances change — a new property purchase, a change in family situation, a change in tax law, or a shift in exchange rates that materially alters the sterling value of your overseas assets.

Using Trusts to Protect Your Estate

Lifetime trusts are one of the most powerful tools in UK estate planning — and they can play an important role in managing the IHT exposure on overseas assets too. A trust is not a legal entity — it is a legal arrangement where the trustees hold legal ownership of the assets for the benefit of the beneficiaries. By placing assets into an irrevocable lifetime trust, you can potentially remove them from your taxable estate, provided the gift with reservation of benefit (GROB) rules are carefully navigated. A revocable trust, by contrast, offers no IHT benefit at all — HMRC treats the assets as still belonging to the settlor.

The most commonly used type for asset protection is a discretionary trust, where the trustees have absolute discretion over how and when to distribute income and capital to the beneficiaries. No beneficiary has a fixed right to anything — which is precisely what provides protection against IHT, care fees, divorce, and bankruptcy. Discretionary trusts can last up to 125 years under English law. They fall within the relevant property regime, meaning there may be periodic charges (maximum 6% of trust value above the NRB every 10 years) and exit charges — but for most families, where the trust value is within the NRB, these charges are zero or negligible.

However, holding overseas property in a UK trust requires careful consideration. Many civil law countries (including France and Spain) do not fully recognise English trusts, which can create complications around local property registration, local tax treatment, and forced heirship rules. In some cases, holding the overseas property through a company structure — or making the trust a shareholder of such a company — may be more practical, though this introduces its own tax and reporting complexities.

For UK investment properties and buy-to-let properties held abroad, Mike Pugh’s Settlor Excluded Asset Protection Trust may be appropriate, as it’s specifically designed for properties the settlor does not live in, avoiding the gift with reservation issues that apply to the family home.

The key point is this: trusts are tax-efficient planning tools, not tax avoidance schemes. They must be set up properly with specialist advice, and the choice of trust type, trustees, and governing law must be tailored to the specific property and jurisdiction involved.

Tax Reliefs and Exemptions

Navigating the complexities of IHT on overseas property requires a thorough understanding of the reliefs and exemptions available. Using them effectively can make a significant difference to the amount of tax your family ultimately pays.

Available Reliefs for Foreign Assets

Several important reliefs can apply when calculating IHT on overseas property:

• Double Taxation Relief: Where a DTA exists between the UK and the country where the property is located, relief is given to prevent the same asset being taxed twice. Where no DTA exists, unilateral relief under UK domestic law can still provide a credit for foreign tax paid.
• Liabilities deduction: Debts secured against the overseas property — such as a local mortgage — can generally be deducted from the property’s value when calculating IHT, reducing the taxable amount.
• Business Property Relief (BPR): If the overseas property is used for genuine business purposes (not merely investment), BPR may be available. However, from April 2026, BPR will be capped at 100% for the first £1 million of combined business and agricultural property, with only 50% relief on the excess.

Claiming these reliefs requires careful documentation and compliance with HMRC’s requirements. It’s essential to maintain detailed records of any foreign tax paid, property values, and associated liabilities.

Other Potential Exemptions

In addition to reliefs specific to foreign assets, several general IHT exemptions can be strategically valuable:

• Spouse/civil partner exemption: Transfers between UK-domiciled spouses or civil partners are fully exempt from IHT — no limit. Where one spouse is non-UK domiciled, there is a capped exemption, but that spouse can elect to be treated as UK domiciled for IHT purposes to access the full exemption (though this brings their own worldwide assets into the UK IHT net).
• Charity exemption: Gifts to qualifying UK charities are fully exempt from IHT. And if you leave at least 10% of your net estate to charity, the IHT rate on the remainder drops from 40% to 36%.
• Normal expenditure out of income: Regular gifts made from surplus income (not capital) that don’t reduce your standard of living are exempt. This can be a powerful exemption for those with regular overseas rental income — but it must be properly documented as a regular pattern of giving.
• Nil rate band: The £325,000 NRB (frozen until at least April 2031) applies to your worldwide estate. Married couples and civil partners can transfer unused NRB to the surviving spouse, giving a potential combined allowance of £650,000.

It’s important to note that the Residence Nil Rate Band (RNRB) of £175,000 per person only applies to a qualifying residential interest in a property that passes to direct descendants (children, grandchildren, step-children). It does not apply to overseas property — it must be a residential property that forms part of the deceased’s estate and passes on death to qualifying beneficiaries. The RNRB also tapers away by £1 for every £2 that the total estate value exceeds £2,000,000, and is not available for properties left to nephews, nieces, siblings, friends, or charities. This is a UK-focused relief and generally cannot help with overseas property IHT planning.

By understanding and using these exemptions effectively, you can protect more of your estate. We strongly recommend reviewing your position regularly with a specialist, as the rules change and your circumstances evolve over time.

Filing Requirements for Overseas Property

Understanding the filing requirements for overseas property is crucial for UK residents who want to ensure compliance with HMRC and avoid penalties that can make an already difficult time even harder for your family.

Understanding the Reporting Process

When someone dies owning overseas property, the executors or personal representatives must include that property in the IHT account submitted to HMRC. This means completing the relevant IHT forms (typically form IHT400 for the full return, along with supplementary schedules for foreign assets) and providing detailed information about:

• The property’s market value at the date of death, supported by a professional valuation and converted into sterling at the exchange rate on that date.
• Any debts or liabilities secured against the property (such as a foreign mortgage).
• Details of any foreign tax paid or expected to be paid, to support a claim for double taxation relief.
• Information about any previous lifetime transfers of the property or related assets.

It’s essential to keep thorough records throughout — including the original purchase documentation, any valuations obtained during the owner’s lifetime, and details of any local tax compliance in the country where the property is situated.

Deadlines and Compliance

Meeting HMRC’s deadlines is critical. The key deadlines to be aware of are:

1. IHT payment deadline: IHT is due within six months from the end of the month in which the death occurred. Interest starts to accrue on unpaid IHT after this date.
2. IHT return deadline: The full IHT400 return must be submitted within twelve months from the end of the month of death. However, in practice, a return typically needs to be filed before the six-month payment deadline, because you cannot obtain a Grant of Probate (or Letters of Administration if there is no will) without first submitting the IHT account and paying (or arranging payment of) any IHT due.

Practical complications with overseas property: Obtaining a professional valuation of foreign property can take longer than valuing UK assets, particularly if you need to instruct local valuers, deal with different time zones, or navigate language barriers. Selling overseas property to fund the IHT bill can also be a much slower process than selling UK property, as you’ll need to navigate the local conveyancing system and comply with local legal requirements. HMRC does allow IHT on property to be paid in annual instalments over ten years, which can help with cash flow — but interest is charged on the outstanding balance.

Failure to comply with reporting and payment deadlines can result in penalties and interest charges from HMRC. Getting professional help early in the process is strongly advisable, particularly when overseas assets are involved.

Common Mistakes to Avoid

When dealing with IHT on overseas property, there are several costly mistakes that we see regularly — and all of them are avoidable with the right advice and planning.

Misunderstanding Tax Liabilities

The most common mistake is simply not understanding the extent of your UK IHT exposure. Many people assume that because their property is abroad, it’s outside the reach of HMRC. That’s only true if you are genuinely non-UK domiciled and not deemed domiciled. If you are UK domiciled — and most British nationals are, even if they live abroad — your worldwide assets are in the IHT net.

• Assuming leaving the UK changes your domicile: Moving abroad does not automatically change your domicile of origin. HMRC has successfully challenged domicile claims in numerous cases where individuals had lived abroad for decades but retained connections to the UK.
• Ignoring foreign tax obligations: Even if a DTA prevents double taxation, you may still need to file returns and comply with local tax rules in the country where the property is situated. Failure to do so can result in penalties from the foreign tax authority.
• Forgetting about the deemed domicile rules: If you’ve been UK resident for 15 of the last 20 tax years, you’re deemed UK domiciled regardless of your actual domicile. This catches many long-term foreign residents of the UK by surprise.
• Not claiming available reliefs: Failing to claim double taxation relief or unilateral relief means paying more tax than necessary. These reliefs are not automatic — they must be actively claimed on the IHT return.

Failing to Update Your Will

Another critical error is failing to keep your will up to date — or, worse, not having a will that properly deals with your overseas property. In many countries, a UK will may not be recognised for the purposes of transferring local property. You may need a separate will in the country where the property is located, drafted under local law, to deal specifically with that asset.

Regularly reviewing and updating your wills is essential — particularly when you acquire or dispose of overseas property, when your family circumstances change, or when the tax law in either country changes. As Mike Pugh says, plan, don’t panic — but do plan.

Seeking Professional Advice

To manage IHT on your overseas property effectively, specialist professional advice isn’t a luxury — it’s a necessity. The law, as Mike Pugh often says, is like medicine: it’s broad. You wouldn’t want your GP doing heart surgery, and you shouldn’t rely on a general legal practitioner when dealing with the intersection of UK IHT law, foreign succession rules, and international tax treaties.

When to Consult a Specialist

You should seek specialist advice:

• Before purchasing overseas property — understanding the IHT and succession implications before you buy can save enormous problems later.
• If you’re a UK national living abroad and unsure of your domicile status.
• If you’ve been a UK resident for approaching 15 out of 20 tax years and may be caught by the deemed domicile rules.
• When dealing with the estate of a deceased person who held overseas property.
• When reviewing your estate plan to ensure it accounts for overseas assets, currency movements, and changes in tax law.
• If you want to explore using irrevocable lifetime trusts for overseas investment property.

Benefits of Professional Guidance

Working with a specialist in inheritance tax planning and trust law provides tangible, measurable benefits:

At MP Estate Planning, we work with clients across the UK who own property overseas. Our approach starts with understanding your full picture — domicile status, family situation, asset values, and objectives — and then building a tailored plan that protects your family’s wealth for the long term. Keeping families wealthy strengthens the country as a whole.

Take Action Today

If you own property overseas and you’re UK domiciled, the question isn’t whether IHT will affect your estate — it’s how much it will cost your family if you don’t plan ahead. With the nil rate band frozen at £325,000 since 2009 and average property values continuing to rise — the average home in England is now worth around £290,000 — more families than ever are being caught by IHT on their combined UK and overseas assets.

Effective inheritance tax planning — including the strategic use of irrevocable lifetime trusts, gifting, double taxation relief, and proper will structuring — can make the difference between your family inheriting your assets and HMRC taking 40% of everything above the threshold. But these strategies take time to implement and, in many cases, require you to survive seven years for the full benefit to crystallise. The earlier you start, the more options you have.
