UK Inheritance Tax on Overseas Property: A Complete Guide

If you own property abroad or are expecting to inherit assets from outside the UK, you may be wondering whether HMRC has a claim on those assets. The short answer is: it depends on your UK residence history. This guide walks you through everything you need to know about how UK Inheritance Tax (IHT) applies to overseas property, who it affects, and how to manage your exposure.

What Is UK Inheritance Tax?

Inheritance Tax is a charge levied on the estate of someone who has died, covering all their property, money, and assets. In the UK, IHT is charged at a standard rate of 40% on the portion of an estate that exceeds the nil-rate band threshold.ibissandco+1

For the 2026/27 tax year, the figures you need to know are:

• Nil-Rate Band (NRB): £325,000 per person, frozen until April 2031
• Residence Nil-Rate Band (RNRB): An additional £175,000, available when the deceased’s main home is left to direct descendants
• Combined threshold (married couple with home to children): Up to £1,000,000
• Reduced rate: 36% if at least 10% of the net estate is donated to a registered charity

If the total estate falls below the available allowances, there is no IHT to pay. Where it exceeds them, the excess is taxed at 40%.

The 2025 Shift: From Domicile to Residence

A landmark change took effect on 6 April 2025, replacing the old domicile-based system with a residence-based system for determining IHT liability on overseas assets.

Under the previous rules, the concept of domicile determined whether non-UK assets were brought into the UK IHT net. From 6 April 2025, that test no longer applies. Instead, liability hinges on whether an individual qualifies as a Long-Term UK Resident (LTR).

This is a significant shift. Long-term residents who previously were not UK-domiciled may now find their worldwide assets subject to UK IHT sooner than under the old regime.

Who Is a Long-Term UK Resident?

An individual qualifies as a Long-Term UK Resident (LTR) for IHT purposes if they have been UK tax resident for at least 10 out of the previous 20 tax years, immediately before the tax year in which:

• A chargeable lifetime transfer (such as a gift) is made, or
• Death occurs

Residence is determined using the UK Statutory Residence Test.

If you ARE a Long-Term UK Resident:
Your worldwide assets, including all overseas property, fall within the scope of UK IHT.

If you are NOT a Long-Term UK Resident:
Only your UK-situated assets are subject to IHT. Overseas property is generally excluded from the charge.

Does UK IHT Apply to Overseas Property?

Yes. The UK government treats overseas property in the same way as domestic property for IHT purposes, provided the deceased was a Long-Term UK Resident. The value of any foreign property forms part of the total estate and is taxed accordingly.

Overseas property held through close companies, partnerships, or trusts is also within scope where the value of the interest is attributable to a UK residential property interest or foreign property owned by a Long-Term Resident.

The Tail Period: IHT Exposure After Leaving the UK

Leaving the UK does not immediately remove your worldwide assets from the IHT net. Long-Term UK Residents who depart the UK remain within the scope of IHT for a period known as the tail period, which ranges from 3 to 10 years depending on how long they previously lived in the UK.

After 10 consecutive tax years of non-residence, LTR status is fully lost and non-UK assets fall entirely outside the UK IHT net.

Avoiding Double Taxation on Foreign Property

One of the biggest concerns with overseas property is the risk of being taxed twice, once by the UK and once by the country where the property is located. There are two key mechanisms that provide relief:

Double Taxation Treaties (DTAs)

The UK has double taxation treaties with a number of countries, including France, Ireland, India, Italy, the Netherlands, Pakistan, South Africa, Sweden, Switzerland, and the United States. Where a DTA exists, it determines which country has the right to tax the inheritance and to what extent, potentially reducing or eliminating the double tax burden.

However, it is important to note that if the foreign country charges inheritance tax at a 0% rate or does not levy a similar tax at all, UK IHT will still apply in full regardless of the DTA.

Unilateral Relief

Where no DTA is in place, UK law provides unilateral relief under section 159 of the Inheritance Tax Act 1984. This allows a credit for foreign tax paid against the UK IHT liability on the same asset, up to the amount of the UK charge. Detailed records of foreign tax paid must be maintained to claim this relief.

Overseas Property That Represents UK Residential Property

A specific anti-avoidance provision introduced under Schedule A1 of IHTA 1984 ensures that overseas property cannot be used as a vehicle to remove UK residential property from the IHT net.

Under these rules, an interest in an overseas close company or partnership is not treated as excluded property if its value is directly or indirectly attributable to a UK residential property interest. This means that structuring UK residential property through an offshore company does not shelter it from IHT. Furthermore, loans used to finance the acquisition of UK residential property, and proceeds from the disposal of such interests, remain within scope for a two-year period following the transaction.

Your Tax Obligations as a Beneficiary

As a beneficiary, you do not pay IHT personally. Inheritance Tax is settled by the estate’s executors before any assets are distributed to you. However, once you receive an overseas property, you take on ongoing UK tax obligations if you are a UK resident:

Income Tax: Any rental income from the inherited property must be declared on a Self Assessment tax return. Allowable deductions include property management fees, maintenance, insurance, and relevant mortgage interest. Foreign Tax Credit Relief can be claimed to avoid double taxation on rental income.

Capital Gains Tax: If you sell the inherited property, CGT applies to the gain calculated from the market value at the date of death to the sale price, less selling costs. Your annual CGT allowance (£3,000 for 2026/27) can offset part of the taxable gain.

Practical Steps to Manage Your IHT Exposure

Managing IHT on overseas property requires proactive planning. Here are the key actions to consider:

1. Check double taxation treaties between the UK and the country where the property is located before making any decisions
2. Review available reliefs, such as Business Property Relief or Agricultural Property Relief, to determine whether they can apply to your overseas assets
3. Make a Will in the relevant jurisdiction to simplify administration and ensure the property passes according to your wishes under local law
4. Consider gifting strategies or trust arrangements well in advance, being mindful of the seven-year rule for gifts and the tail period for LTR status
5. Keep thorough records of foreign tax paid to support claims for double taxation relief
6. Seek specialist advice from professionals with expertise in both UK and international tax law to ensure full compliance
