UK Inheritance Tax: What Foreign Property Buyers Need to Know

If you own UK residential property and you die, that property is within the scope of UK Inheritance Tax, whether or not you have ever lived in the UK. Inheritance Tax follows where the asset is, not where you are.

The standard rate is 40%, charged on the part of the estate above the £325,000 nil-rate band. There is a reduced rate of 36% where 10% or more of the net value of the estate is left to charity. Verified on GOV.UK, 25 August 2026.

Holding the property through a non-UK company doesn’t take it out of scope. That route was closed in 2017.

Why UK property is caught

Under UK Inheritance Tax rules, property situated outside the UK is excluded property when the owner is not a long-term UK resident. Property situated inside the UK is not excluded. Your UK house is UK-situated, so it is chargeable. Verified on GOV.UK, 25 August 2026.

That’s the whole of the logic. It isn’t about your nationality, your visa, or how many days you spend here.

What changed in April 2025, and what did not

From 6 April 2025 the domicile and deemed domicile rules were replaced by a residence-based test. You are a long-term UK resident if you have been UK tax resident for the previous 10 consecutive years, or for a total of 10 years or more within the previous 20 tax years. Verified on GOV.UK, 25 August 2026.

Becoming a long-term UK resident brings your worldwide assets into UK Inheritance Tax. Having left the UK, you can remain in scope for between 3 and 10 further tax years depending on how long you were resident.

What didn’t change is the position on UK property. Whether or not you’re a long-term UK resident, your UK house is in scope. The 2025 reform decides how much of the rest of your wealth comes with it.

The offshore company route was closed in 2017

Since 6 April 2017, an interest in a non-UK close company or an overseas partnership is not excluded property for Inheritance Tax to the extent its value is attributable to UK residential property. The same applies to loans used to acquire, maintain or enhance UK residential property, and to money or assets held as security or collateral for those loans. Verified on GOV.UK, 25 August 2026.

If you were sold a BVI or Jersey structure on the basis that it removes UK Inheritance Tax from a UK house, it doesn’t. It only removes the value that isn’t attributable to the UK residential property, which for a company whose only asset is a UK house is nothing.

The allowances, and one that probably will not apply to you

The nil-rate band is £325,000. Above that, 40%.

The residence nil-rate band can lift the combined threshold to £500,000 where a home is passed to children or grandchildren and the estate is worth less than £2 million. Verified on GOV.UK, 25 August 2026.

The catch for investors: the residence nil-rate band is designed for a home the deceased lived in. A buy-to-let house you have never occupied is very unlikely to qualify. Don’t build a plan on it without checking the position with an adviser.

When the tax has to be paid, and by whom

Inheritance Tax is due by the end of the sixth month after the month in which the person died, and HMRC charges interest after that. Verified on GOV.UK, 25 August 2026.

Two practical consequences catch families out:

You normally have to start paying before probate is granted, and where the estate owes Inheritance Tax you must report its value on form IHT400 before you can apply for probate at all. Verified on GOV.UK, 25 August 2026.
The property can’t be sold to pay the bill until probate is granted. So the money has to come from somewhere else first.

There is relief for that. Inheritance Tax on land and buildings, including houses, can be paid in equal annual instalments over 10 years, provided the property has not been sold, and you will usually pay interest on the instalments. Verified on GOV.UK, 25 August 2026.

Being taxed twice, and the relief for it

Your home country may also tax the same estate. The UK has Inheritance Tax double taxation conventions with the Republic of Ireland, South Africa, the USA, the Netherlands, Sweden and Switzerland, plus older pre-1975 treaties with France, Italy, India and Pakistan which work differently. Verified on GOV.UK, 25 August 2026.

Where there’s no convention, unilateral relief can give credit against UK Inheritance Tax for foreign tax charged on assets sited in that country, limited to the lower of the two. If you’re in a treaty country, the treaty rules matter and an adviser needs to read them against your facts.

What actually reduces the exposure

There’s no clever structure that makes a UK house disappear from a UK estate. What exists is ordinary planning, all of which needs professional input:

Gifts. No Inheritance Tax is due on a gift if you live for 7 years after making it. Die within that window and the charge tapers where the gift exceeds the nil-rate band: 32% for gifts 3 to 4 years before death, 24% at 4 to 5 years, 16% at 5 to 6 years, 8% at 6 to 7 years. Gifts within 3 years of death are charged at the full 40%. There is also a £3,000 annual exemption. Verified on GOV.UK, 25 August 2026.
But not a gift with strings. If you give the house away and keep the rent, or keep the right to use it, the gift with reservation of benefit rules generally pull it straight back into your estate. This is the single most common mistake.
Spouse and civil partner exemption. Transfers between spouses are generally exempt, but where the receiving spouse isn’t a long-term UK resident the exemption is capped and an election may be available. This is genuinely technical. Don’t guess at it.
Life insurance written in trust. Doesn’t reduce the tax. It provides cash outside the estate to pay it, which solves the timing problem above. For many overseas owners of a single UK property this is the most practical answer.
A UK will covering your UK assets. Not a tax saving, but it stops the administration becoming slow and expensive, and it avoids a conflict with a will made under another country’s rules.

Keep it in proportion

The nil-rate band is £325,000. The four purchases I’ve written up in full were bought at £61,500, £65,000, £78,000 and £90,000. A single house in South Yorkshire or North Nottinghamshire held by someone with no other UK assets may sit under the threshold entirely.

That changes as you buy more, and it changes if you become a long-term UK resident and your worldwide wealth comes into scope. The planning question is worth asking early, and worth asking again when the second and third purchases happen.

What to do next

Find out two things: the total value of your UK-situated assets, and whether your country has an Inheritance Tax treaty with the UK. Those two facts shape every conversation that follows.

This is not tax or legal advice. Inheritance Tax is one of the more technical parts of the UK system, the rules changed materially in April 2025, and the interaction with your home country’s succession and tax rules cannot be generalised. Every figure above was checked against GOV.UK on 25 August 2026 and should be re-checked before you act on it. An overseas buyer needs a UK tax adviser, and usually an adviser in their own country too. Speak to one before you buy, not after.
