Avoid Double Taxation on Overseas Property Inheritance

We’re here to help families protect what matters. In plain English, this guide explains why an estate can face inheritance tax (IHT) bills in more than one country — and what that looks like in practice for ordinary UK homeowners with property abroad.

HMRC can treat foreign property as part of a taxable estate. The standard UK rate is 40% on the value above available allowances, so this risk matters to far more households than most people realise. With the nil rate band frozen at £325,000 since 2009 — and not due to rise until at least April 2031 — rising property values mean more families are caught every year.

From April 2025, long‑term residence rules replaced the old domicile framework as the gateway into worldwide IHT. That affects old planning assumptions and means some families who thought they were safe are now exposed.

We set out practical steps below: treaty relief, foreign tax credits, careful valuation and clear HMRC reporting. We explain what works and what does not, so you can avoid costly mistakes and delays.

Key Takeaways

• UK IHT rules can include worldwide assets — including foreign property — so plan early.
• Expect possible overlap with another country’s inheritance or estate levy and use treaty relief where available.
• From April 2025, the new long‑term residence rules may alter planning options for internationally mobile families.
• Practical tools include: foreign tax credits, bilateral treaties, accurate date-of-death valuations and clear HMRC reporting.
• Avoid “magic” offshore fixes — they often bring more risk and cost than they save.

Why double taxation happens when inheriting overseas property

We often see one asset attract claims from two different tax systems. A holiday home might be taxed in the country where it sits and again in the UK, where the deceased or beneficiary is treated as resident for IHT purposes.

What this means in practice

One asset, two tax bills. Take a UK-based beneficiary who inherits a flat in Spain. Spanish succession tax may be assessed locally. HMRC may also include the same property when valuing the deceased’s worldwide estate for inheritance tax purposes. The result: two separate charges on the same asset.

Common triggers

• Asset location (situs): the country where the property sits often has primary taxing rights under its own domestic law.
• Residence status: the deceased’s UK residence or long‑term residence status can create a second claim by bringing worldwide assets into scope for IHT.
• Conflicting rules: different countries define “estate,” “residence” and available reliefs in different ways, leading to overlap.

Why it matters

These overlaps directly reduce what heirs receive. They can also cause serious cashflow pressure — if inheritance tax is due before a foreign property can be sold, executors may need to find liquidity from other sources. That leads to rushed decisions and added costs at exactly the wrong time.

We will show how treaty relief, foreign tax credits and clear reporting can reduce these tax implications. Start early and establish which country has primary taxing rights. For more on the bilateral agreements that help, see our guide: double taxation agreements.

How UK inheritance tax applies to foreign assets and overseas property

If someone is UK resident — or meets the long‑term residence test — assets held abroad may still form part of their estate for IHT purposes. This catches many families by surprise.

Worldwide assets and IHT for UK residents

HMRC assesses IHT on the worldwide estate of anyone who is UK domiciled or who meets the long‑term residence test. That means foreign property, overseas bank accounts and investments held abroad are all valued and reported alongside UK holdings.

What this means day‑to‑day:

• The estate valuation for IHT must list all global holdings — not just UK assets.
• Foreign property titles, bank balances and shareholdings abroad all count towards the taxable estate.
• Even if a property has never been connected to the UK in any practical sense, it may still be subject to IHT at 40% above the available nil rate band.

When an overseas property is treated the same as UK property

For IHT purposes, an overseas property is not treated differently from a UK property once the deceased falls within scope. HMRC applies the same valuation rules, the same reporting requirements and the same tax rates. The complexity lies in how foreign succession taxes and local legal processes interact with UK rules — and whether any relief is available to prevent the estate being taxed twice.

For a practical guide on holiday homes and how foreign charges are treated, see inheritance tax on overseas holiday homes.

UK IHT thresholds and rates to know for current planning

Knowing the key thresholds helps you see whether a single overseas asset could push an estate into chargeable territory. With average UK house prices now around £270,000–£290,000 before any foreign property is added, more estates are breaching these limits than ever before.

Nil‑rate band (NRB)

The nil‑rate band is the first allowance that reduces an estate’s value for inheritance tax purposes. It currently stands at £325,000 per person. It has been frozen at this level since 6 April 2009 and is confirmed frozen until at least April 2031. Any unused NRB can transfer to a surviving spouse or civil partner, giving a married couple up to £650,000 combined.

Residence nil‑rate band (RNRB)

The residence nil‑rate band provides an additional allowance of £175,000 per person when a qualifying residential interest passes to direct descendants — that means children, grandchildren or step-children. It is not available where the property passes to nephews, nieces, siblings, friends or charities. It is also transferable between spouses, giving a maximum of £350,000 for a couple. The RNRB tapers away by £1 for every £2 that the estate exceeds £2,000,000 in value.

A foreign holiday home will not normally qualify for the RNRB unless it was the deceased’s main residence and passes to direct descendants. In most cross-border situations, only the UK family home will attract this relief.

How the 40% rate and taxable estate work

The taxable estate is calculated by adding all worldwide assets, deducting allowable debts and liabilities, and then applying the available bands. If the net estate exceeds the combined allowances, the excess is charged at the standard 40% rate. A reduced rate of 36% applies if 10% or more of the net estate is left to charity.

Example: estate value £600,000 (including a UK home and a small apartment abroad). Subtract the NRB of £325,000 and the RNRB of £175,000 (assuming it applies). Taxable amount = £100,000. IHT at 40% = £40,000.

Practical cashflow point: IHT is paid by the estate, typically before a Grant of Probate is issued in England and Wales. If the main asset is a building abroad, executors may need to find liquidity from other sources — a UK bank account, borrowing, or a life insurance payout — to settle the HMRC bill before a foreign sale can complete. That can force hurried decisions and reduce what beneficiaries ultimately receive.

Long-term residence rules since April 2025 and why they change everything

Since 6 April 2025, the main gateway into worldwide IHT moved from domicile to long‑term residence. This is the most significant change to cross-border IHT in a generation and matters for anyone with foreign assets and international family ties.

What counts as a long‑term resident

A long‑term resident is a person who has been UK tax resident for at least 10 of the previous 20 tax years. That test catches many internationally mobile families — including those who assumed they had become “non-domiciled” for IHT purposes under the old rules.

The IHT “tail” after leaving the UK

Leaving the UK does not end IHT exposure immediately. A departing long‑term resident carries an IHT “tail” that can last up to 10 years, during which their worldwide assets remain within scope.

• 10–13 years’ UK residence → tail of at least 3 years after departure.
• Each additional year of prior UK residence generally adds one year to the tail, up to a maximum of 10 years.
• The result is potential continued liability to IHT on non‑UK assets — including overseas property — even while you are living and tax resident abroad.

Where domicile still crops up

Old trusts settled before April 2025 may still reference domicile rules. Bilateral double taxation treaties also typically use domicile as a connecting factor. Some transitional provisions still refer to domicile status, so it has not disappeared entirely. Check older arrangements in any estate planning review to confirm whether the new residence-based rules or legacy domicile provisions apply.

Double taxation on inheritance for overseas property owners UK: who is most at risk

When assets span borders, the risk of parallel estate charges rises quickly. Three groups commonly face the squeeze — and recognising where you fall is the first step towards protecting the estate.

UK residents inheriting from a foreign estate

UK residents who inherit a foreign asset may face a local succession tax or inheritance levy in the country where the property sits, plus a UK IHT charge if the deceased’s worldwide assets are in scope. That can create serious cashflow pressure — particularly if local tax must be settled before the property can be sold or transferred.

Long‑term residents who still own foreign assets

People who meet the long‑term residence test (10 out of 20 tax years in the UK) but keep foreign homes or investments remain liable on their worldwide estate. The new residence-based rules since April 2025 make this situation more common, catching families who previously relied on non-domiciled status to exclude overseas assets.

Families with assets across several countries

Each additional jurisdiction adds valuation work, local legal processes, potential succession tax and possible probate-equivalent steps. A UK house plus an Irish cottage and a French apartment is a recipe for compounding delays, professional fees and overlapping tax charges.

• Why even one foreign property can be risky: local situs rules often give primary taxing rights to the country where the asset sits — regardless of UK planning.
• Early advice matters: checking the relevant treaty position and obtaining local tax input can save significant time and money before you need to file UK IHT returns.
• Red flags to watch for: multiple wills that may conflict, foreign mortgages, shared or joint ownership structures, and complex family arrangements across jurisdictions.

Work out which country can tax the inheritance first

Begin with the fundamental question: which jurisdiction will claim the estate first? Mapping taxing rights before any other action helps avoid surprise bills and rushed property sales.

Tax in the country where the property is located

The country where the property sits usually has the primary claim. Under most countries’ domestic law, immovable property (real estate) is subject to local succession or inheritance tax at death regardless of the owner’s nationality or residence.

That means local probate-equivalent proceedings and a local tax charge may be due before any sale or transfer can proceed. Executors must factor this into their liquidity planning from day one.

Tax in the UK based on residence status and worldwide assets

If the deceased was UK resident or met the long‑term residence test, HMRC will include worldwide assets when assessing IHT — including the same foreign property already subject to local tax.

That creates a second claim on the same asset, which is the core of the double taxation problem.

How dual connections create overlapping IHT liability

Dual connections arise when one country taxes the property because it sits within its borders, and the UK taxes the same property because of the deceased’s residence status. The result is overlapping IHT liability — two tax bills on the same value.

Why this matters: without identifying the correct taxing rights early, you may miss treaty relief claims, fail to gather the right evidence for a foreign tax credit, or face late‑payment interest from one or both jurisdictions.

• Which country has situs rights to the property (usually straightforward — where it physically sits)?
• Was the deceased UK resident or a long‑term resident at death?
• Is there documented evidence of foreign tax paid that supports a credit claim against UK IHT?
• Key documents to collect early: death certificate, property title deeds, residency records, local tax assessments and receipts of foreign tax paid.

Use UK inheritance tax double taxation treaties to reduce or eliminate overlap

Bilateral treaties decide who taxes first and how relief works. Where a treaty exists, it can prevent two countries each taking a full charge on the same asset — potentially saving the estate tens of thousands of pounds.

What a treaty does in practice

Double taxation treaties (also called double taxation agreements or conventions) allocate taxing rights between the UK and the other country. They typically set out which country has the primary right to tax specific categories of assets, and provide a mechanism — usually a tax credit — so the total charge does not exceed what the higher-taxing country would have taken alone.

Countries to check early

The UK currently has bilateral inheritance tax treaties with a limited number of countries. The key ones to check are:

• Ireland, USA and South Africa;
• France, Netherlands and Sweden;
• Switzerland, Italy, India and Pakistan.

For countries without a treaty — including Spain, Portugal and most of the popular retirement and holiday destinations — unilateral relief under UK domestic law may still provide a credit, but the rules are different and the process requires careful evidence.

How the cap works and practical steps

Cap concept: some treaties ensure the combined charge from both countries cannot exceed the higher of the two individual assessments. In practice, this means the total tax bill should be no worse than if only one country were involved.

Treaties are not automatic. Executors must actively claim relief, submit evidence of foreign tax paid and meet filing deadlines in both jurisdictions. Good inheritance tax planning identifies these steps well before death, so executors know exactly what to do.

Long‑term residence and post‑April 2025 treaty interactions

From 6 April 2025, HMRC treats long‑term residents as within scope for worldwide IHT, replacing the old deemed domicile concept. However, most existing treaties still use domicile as a connecting factor. This mismatch can create uncertainty about how treaty relief applies in practice. Specialist cross-border advice is essential to navigate this transitional period correctly.

Claim credit or relief when foreign inheritance tax is also charged

If inheritance or succession tax has been paid overseas on the same asset, that payment can sometimes reduce what the estate owes HMRC. Here we explain the credit route and the paperwork that gives it force.

When a foreign tax credit may apply

Where the same asset faces tax in two countries, executors may be able to offset the foreign tax paid against the UK IHT liability. If a bilateral treaty exists, it will set out the credit mechanism. Where there is no treaty, UK domestic legislation provides for unilateral relief — allowing a credit for foreign tax paid on the same asset, up to the amount of UK IHT attributable to that asset.

Evidence and paperwork you’ll need to support a claim

Claims succeed on clear documentary proof. Executors should gather:

• official foreign tax assessments and receipts showing the amount of overseas tax paid;
• formal property valuations at the date of death that match the reported value on both the foreign filing and the UK estate account;
• certified translations where documents are not in English;
• proof of ownership — title deeds, land registry records and local probate-equivalent grants;
• bank payment records showing the foreign tax was actually settled.

Common errors that delay relief and increase estate costs

Missing or inconsistent documents are the usual culprits. Executors frequently submit valuations that do not match between jurisdictions — if you tell HMRC the property is worth £250,000 but told the Spanish authorities it was worth €320,000, expect questions. Late submissions, unclear ownership records and poor coordination between UK and foreign advisers also slow the process considerably.

Our practical advice: get coordinated advice from both a UK specialist and a local adviser in the country where the property sits, and keep a tidy, shared file. That saves the estate both time and unnecessary tax. For wider guidance on avoiding overlapping charges, see our guide on navigating inheritance tax on overseas property in the UK.

Handle valuations, currency, and reporting to HMRC correctly

Valuing foreign assets requires care and precision. Executors must present a clear, UK‑style open market value and demonstrate exactly how they arrived at the sterling figure reported to HMRC.

Valuing overseas property and dealing with exchange rates

Obtain a local professional valuation dated at the date of death — not the date you instruct the valuer, and not the date of sale. Then convert that figure to pounds sterling using the spot exchange rate on the date of death. HMRC publishes exchange rates, and using their published rate for that date is the safest approach.

Why that matters: inconsistent conversion dates, averaged rates or use of mid‑market estimates can trigger HMRC queries and potentially delay the Grant of Probate.

Reporting foreign assets as part of the deceased’s estate

Include every non‑UK asset when completing the IHT estate accounts for HMRC. Ensure the narrative description and sterling figures are consistent with any local filings in the country where the property sits. Contradictions between UK and foreign returns are a common trigger for enquiries.

Keep copies of everything: valuations, title deeds, foreign tax receipts, exchange rate evidence and certified translations. These documents support claims for foreign tax credits or treaty relief and will be needed if HMRC raises queries.

Managing administration costs across jurisdictions

Budget for local fees early: notary charges, local probate or succession equivalents, land registry fees, certified translations and specialist valuation reports. These costs add up quickly and drain estate liquidity — sometimes at exactly the moment when UK IHT also falls due.

• Plan cashflow: assess whether the estate has enough liquid assets to meet local charges and UK IHT before any foreign property sale can complete.
• Coordinate advisers: appoint a UK lead who shares all documentation with local solicitors, valuers and tax advisers in the foreign jurisdiction.
• Organise a checklist: dated valuation at date of death, certified translations, exchange rate evidence, foreign tax payment receipts, local and UK probate papers.

Get the executor and beneficiary actions right on cross-border estates

Managing an estate that spans borders demands clear steps, steady communication and a willingness to deal with two (or more) legal systems simultaneously. Executors and beneficiaries both need to know what to expect and who is responsible for what.

What executors must do when the estate includes foreign property

Executors must locate all assets worldwide, confirm legal ownership, and obtain professional valuations at the date of death. They must report foreign assets to HMRC on the IHT estate accounts and comply with any local reporting obligations in the country where the property sits.

Extra steps commonly include: appointing a local solicitor or notary in the foreign jurisdiction, ordering land registry searches abroad, arranging certified translations of deeds and documents, and securing evidence of any foreign tax paid (which underpins any credit claim in the UK).

What beneficiaries should expect: delays, local processes, and fees

Expect longer timescales when an estate includes an asset abroad. Local succession processes — the foreign equivalent of probate — can block any sale or transfer of the property until cleared. That slows the entire estate administration, not just the overseas element.

Professional fees in the foreign jurisdiction, translation costs, and local registry charges are standard. These are a normal part of cross-border administration, not a sign that something has gone wrong.

A critical warning for executors: distributing assets to beneficiaries too early can create personal liability for the executor if a later tax assessment appears — from either HMRC or the foreign jurisdiction. Always obtain clearance from both tax authorities before making final distributions.

How to reduce friction: agree early whether the family intends to sell or keep the foreign property, appoint a single UK lead adviser who coordinates with foreign counsel, and use shared document folders so everyone works from the same information. These straightforward steps save time and significantly reduce the risk of costly mistakes.

Consider local succession rules and whether a foreign will is needed

Legal title, not nationality, often decides who controls a property after death. The law of the country where a building sits normally governs the transfer process — known as the lex situs principle. That can make a locally compliant will far more than a mere convenience.

We recommend considering a separate will for each jurisdiction where you own property. A local document drafted to meet in-country formalities can speed the succession process and avoid the delays and expense of having a UK will formally recognised abroad.

When a local will simplifies administration

• Local succession authorities may accept a locally compliant will without the delays of formal translation, apostille or court recognition proceedings.
• A properly drafted foreign will can prevent the need for costly court interventions and speed up the transfer of title to beneficiaries.
• It helps executors demonstrate clear title to foreign banks, land registries and notaries.

Avoiding conflicts between wills and laws across countries

Two wills can unintentionally clash — the most dangerous scenario is where a later will inadvertently revokes an earlier one, or where both wills purport to deal with the same asset. Careful drafting is essential: each will should contain a clear jurisdictional scope clause, specifying exactly which assets it covers, and explicit wording that it does not revoke the other will.

Why this matters for inheritance tax planning: neatly coordinated documents support treaty claims, simplify the foreign tax credit process and reduce disputes that eat into the estate’s value. Ensure your UK solicitor and local foreign adviser work together so that the estate plan, wills and local title deeds all align.

Use legitimate inheritance tax planning strategies that stand up to scrutiny

Sound estate planning relies on practical, transparent measures — not clever-sounding shortcuts that crumble under HMRC scrutiny. We focus on steps that genuinely reduce risk, protect family wealth and hold up if the files are reviewed. As we always say: plan, don’t panic.

Gifting and the seven‑year rule, plus overseas gift tax traps

Outright gifts to individuals are treated as potentially exempt transfers (PETs) for IHT purposes. If the donor survives seven years, the gift falls outside the estate completely. If the donor dies within seven years, the gift uses available nil rate band first, with any excess taxed at 40%. Taper relief reduces the tax (not the value of the gift) on a sliding scale from years 3 to 7, but only applies where the total gifts exceed the £325,000 nil rate band.

Watch out: some countries treat lifetime gifts very differently. Local gift taxes, transfer charges or withholding rules in the country where the property sits can create unexpected charges or additional reporting duties. Always take local advice before gifting foreign property.

Also note: PETs only apply to gifts to individuals. Transfers into discretionary trusts are chargeable lifetime transfers (CLTs) with different rules — an immediate 20% charge on value above the available nil rate band.

Life insurance to cover an IHT bill

A life insurance policy is a practical way to ensure the estate has liquidity to meet an IHT bill without forcing a rushed sale of the foreign property. The policy does not remove the tax liability, but it funds the bill so heirs are not left scrambling.

Critical tip: place the policy in trust. A Life Insurance Trust ensures the payout goes directly to the intended beneficiaries, bypasses probate delays and — most importantly — keeps the proceeds outside the taxable estate. Without a trust, the payout simply adds to the estate value and increases the IHT bill. Setting up a Life Insurance Trust is typically straightforward and can be done at no additional cost.

Reliefs that may apply, including business or agricultural relief

Business Property Relief (BPR) and Agricultural Property Relief (APR) can reduce the taxable value of qualifying assets significantly — historically at 100% for qualifying business and agricultural property. However, from April 2026, BPR and APR will be capped at 100% relief for the first £1 million of combined qualifying property, with relief reduced to 50% on any excess.

• Check qualifying conditions carefully — foreign property may not meet the UK tests for BPR or APR.
• Specialist advice is essential before assuming these reliefs apply to overseas assets.

Why “magic” offshore structures often fail under anti‑avoidance rules

Offshore trusts, holding companies and nominee arrangements can sound attractive on paper. In practice, UK anti‑avoidance rules — including the Gift with Reservation of Benefit (GROB) rules, the Pre-Owned Assets Tax (POAT) charge, and the general anti-abuse rule — often look straight through these structures and reassign the tax consequences to the estate.

The result is frequently worse than doing nothing: the family has paid for an expensive structure that provides no IHT benefit, while also creating additional compliance costs and HMRC scrutiny.

Our advice: get joined‑up planning with UK and local advisers working together. A coordinated plan saves tax and, more importantly, spares families the rush and stress of sudden property sales at difficult times. Not losing the family money provides the greatest peace of mind above all else.

Plan ahead if you’re leaving the UK but still hold overseas property

Moving abroad involves more than boxes and flights — it can fundamentally reshape how your estate is treated for UK inheritance tax. The new rules since April 2025 make advance planning more important than ever.

Timing your move in light of the long-term residence test

Since 6 April 2025, the long‑term residence test (10 out of 20 tax years) determines whether you are treated as within scope for worldwide IHT. If you meet this test at the point of departure, your worldwide assets — including overseas property — remain subject to UK IHT during the “tail” period after you leave.

The tail can last up to ten years. The longer your period of UK residence before departure, the longer the continued liability. This means a family who has lived in the UK for 20 years and then moves abroad could face up to 10 years of continued worldwide IHT exposure.

Reducing exposure during the tail period without creating new liabilities

Plan carefully. Lifetime gifts or transfers can reduce future IHT liability, but they may trigger local transfer taxes, gift taxes or capital gains charges in the country where the property sits. Gifts of foreign property may also engage the GROB rules if you continue to use or benefit from the asset after giving it away.

Coordinate with both UK and local advisers, and check whether a relevant double taxation treaty affects the position before making any transfer. A treaty can determine whether a foreign tax credit is available and how taxing rights are allocated during the tail period.

• Checklist before moving: complete residency history for the last 20 years, full worldwide asset schedule, title deeds for all properties, current wills in every relevant jurisdiction, and recent property valuations.
• Agree who leads the planning — ideally a UK specialist with cross-border experience — and keep records of all actions, decisions and payments.
• Focus on outcomes: protect family wealth, ensure executors know what to do, and avoid surprises that force hurried decisions.

Conclusion

Small, well-documented steps taken early avoid big problems for heirs.

Inheriting or passing on an overseas property can expose an estate to extra tax and possible double taxation — but the risk is manageable with the right sequence of actions and proper professional guidance.

First, confirm residency status and whether the long‑term residence tail applies. Next, identify which country has primary taxing rights over the property. Then seek available treaty relief or foreign tax credits to reduce or eliminate the overlap.

Keep clean, date-of-death valuations, consistent currency conversions, and clear HMRC reporting. Remember the headline bands: the nil rate band at £325,000 (frozen until at least 2031) and the residence nil rate band at £175,000 for qualifying estates — these determine whether and how much IHT is due.

Get early, joined‑up professional help — a UK estate planning specialist plus local counsel in the country where the property sits. With calm, proactive planning, you protect the estate and leave a smoother legacy for the people you love. As we always say: trusts are not just for the rich — they’re for the smart. Plan, don’t panic.
