A UK property is always within the scope of UK Inheritance Tax when its owner dies, regardless of where that owner lives, holds citizenship, or is treated as resident for other UK taxes. IHT is charged at 40 percent on the value of the estate above the 325,000 pound nil rate band, and since April 2025 the rules that decide whether an owner’s worldwide assets are also caught have changed from a domicile test to a residence based test.
Short answer: Yes. Non-residents pay UK inheritance tax on UK property. HMRC charges 40 percent on the value above the 325,000 pound nil rate band, because UK situs assets are always within the IHT net on death. Since 6 April 2025 the Inheritance Tax Act 1984 uses a residence based test for worldwide assets. Full details are on gov.uk.
Why Non-Residents Are Still Liable
UK Inheritance Tax has always applied to UK situated assets no matter where the owner lives. A house in Mayfair, a country estate in Surrey, or a flat bought as an investment all count as UK situs property, and their value falls into the estate calculation on death even if the owner never spent a day in the UK. This is separate from income tax or capital gains tax residence rules, and it catches buyers who assume that being non-resident for other purposes keeps them outside UK inheritance rules entirely.
The 2025 Shift From Domicile to Residence
Before 6 April 2025, a non-UK domiciled owner’s liability was generally limited to UK assets, while their worldwide estate stayed outside the charge. From that date, HMRC uses a long-term residence test instead. An owner who has been UK resident for 10 of the previous 20 tax years is treated as a long-term resident, and their worldwide estate becomes subject to UK Inheritance Tax, not just their UK property.
A tail provision then keeps a former long-term resident within scope for a period after they leave the UK, with the exact length depending on how many of those 20 years were spent as UK resident. For a buyer who has lived and worked in the UK before relocating abroad, this tail can matter more than the property purchase itself, and it should be checked with a UK tax adviser rather than assumed away.
The old deemed-domicile rule, which pulled worldwide assets into IHT after 15 years of UK residence in 20, has been abolished outright. Under the new system the test is purely residence based: 10 years of UK residence out of the previous 20 makes someone a long-term resident for IHT purposes. The 2025 rule changes also rewrote the trust position. Non-UK assets settled into an excluded property trust are now only outside the IHT net while the settlor is not a long-term resident; if the settlor later meets the 10-year test, the trust’s non-UK assets can be pulled into charge on ten-year anniversaries and when assets leave the trust.
For non-residents who never reach the 10-year threshold, the practical outcome is narrower than headlines suggest: only UK situs assets, meaning the property itself, are within scope, taxed at 40 percent above the 325,000 pound nil rate band. But anyone who lived in the UK for a decade or more before buying from abroad needs to check the tail provision. A former long-term resident stays within the worldwide IHT net for between three and ten years after leaving, depending on how long they were resident, and during that tail their worldwide assets remain exposed.
Worked Example at Luxury Price Points
Consider a non-resident, non-long-term-resident owner whose only UK asset is a 4,000,000 pound house in Kensington, held personally and left to adult children. The nil rate band shelters the first 325,000 pounds. The remaining 3,675,000 pounds is taxed at 40 percent, giving an Inheritance Tax bill of roughly 1,470,000 pounds, payable by the estate before the property can be transferred or sold.
On an 8,000,000 pound property under the same conditions, the taxable value after the nil rate band is 7,675,000 pounds, producing a bill of roughly 3,070,000 pounds. These figures assume no other reliefs apply and no double tax treaty offset is available, and they should always be checked against the current thresholds and the estate’s full circumstances before relying on them.
How Much Inheritance Tax Do Non-Residents Pay on UK Property?
For a non-resident who is not a long-term UK resident, the calculation is mechanical. UK Inheritance Tax is charged at a flat 40 percent on the value of UK situs assets above the 325,000 pound nil rate band. The residence nil rate band for passing a main home to direct descendants is generally unavailable where the property was never the owner’s main residence, so most non-resident investors should assume the standard 325,000 pound figure. Here is the step-by-step walkthrough for the two price points above.
4,000,000 pound Kensington house, held personally:
Step 1, start with the property value: 4,000,000 pounds.
Step 2, deduct the nil rate band: 4,000,000 minus 325,000 equals 3,675,000 pounds taxable.
Step 3, apply the 40 percent rate: 3,675,000 multiplied by 40 percent equals 1,470,000 pounds of IHT due.
8,000,000 pound property, same conditions:
Step 1, property value: 8,000,000 pounds.
Step 2, less the nil rate band: 8,000,000 minus 325,000 equals 7,675,000 pounds taxable.
Step 3, at 40 percent: 7,675,000 multiplied by 40 percent equals 3,070,000 pounds of IHT due.
| Property value | Less nil rate band | Taxable amount | IHT at 40 percent |
|---|---|---|---|
| 4,000,000 pounds | 325,000 pounds | 3,675,000 pounds | 1,470,000 pounds |
| 8,000,000 pounds | 325,000 pounds | 7,675,000 pounds | 3,070,000 pounds |
Three adjustments can move these figures. First, an outstanding mortgage reduces the taxable value, because IHT is charged on net equity: a 4,000,000 pound property with a 1,500,000 pound mortgage is taxed on 2,500,000 pounds, not 4,000,000. Second, the nil rate band can be higher where unused allowance transfers from a deceased spouse, potentially doubling it to 650,000 pounds. Third, a double tax treaty, for example with the United States or France, may credit foreign tax against the UK bill. And because the estate pays before probate is granted, liquidity planning matters as much as the arithmetic.
The Offshore Company Route No Longer Works
Before April 2017, holding UK residential property through an offshore company was a common way to keep it outside the IHT net, because shares in a foreign company were themselves treated as excluded property. HMRC closed this route from 6 April 2017. Since then, the value of an offshore company’s shares that comes from UK residential property is brought back into the scope of UK Inheritance Tax on a chargeable event such as the owner’s death, so buyers who structured a purchase this way before 2017 should have the arrangement reviewed rather than assuming it still shelters the property.
The post-2017 position: since 6 April 2017, shares in an offshore company are no longer excluded property to the extent that their value derives from UK residential property (Schedule A1 to the Inheritance Tax Act 1984). On the owner’s death, HMRC looks through the company and taxes the UK property value sitting inside it, and the same look-through applies to loans and collateral connected with the property. Many owners responded by de-enveloping, taking the property out of the company, but that step can itself trigger capital gains tax and stamp duty land tax, so it needs careful modelling before any action is taken. Read our guide to non-resident capital gains tax before acting.
The post-2025 position: the 2025 residence reforms did not reopen the offshore route. Enveloped UK residential property remains fully within IHT, and if anything the net has widened: where the owner is a long-term UK resident under the new 10-of-20-year test, non-UK assets sitting alongside the property inside the same structure can now be pulled into the worldwide charge as well. ATED, the annual tax on enveloped dwellings, also continues to apply to company-held residential property worth over 500,000 pounds, with its own reliefs and filing obligations. Legacy enveloped structures therefore need a full review under both the 2017 look-through rules and the 2025 residence test, not just one or the other.
How the Bill Gets Paid
IHT is owed by the estate, not by the beneficiaries directly, and is generally due six months after the end of the month of death, with interest accruing on late payment. Because the tax is usually due before probate is granted and before the property can be sold, executors of a non-resident owner’s estate often need to fund the bill from other assets, a mortgage against the property, or HMRC’s instalment option for property, which allows payment over 10 years with interest on the outstanding balance.
Reducing the Exposure
A small number of practical steps come up repeatedly in non-resident IHT planning for UK property.
- Life insurance written into trust: a policy written under trust from the outset pays out to beneficiaries directly and sits outside the estate, giving the family funds to cover the tax bill without needing to sell the property quickly.
- Reviewing pre-2017 company structures: older enveloping arrangements should be checked against the current rules rather than assumed to still work. Buyers choosing a structure today should compare the limited company pros and cons with a UK tax adviser.
- Tracking the long-term residence tail: owners who have spent time UK resident before buying should know whether they are still inside the 10-of-20-year test before assuming only their UK property is at risk.
- Checking for a double tax treaty: the UK has a limited number of estate tax treaties, including with the United States and France, which can sometimes credit tax paid in one country against the other.
None of these substitute for advice from a UK-qualified tax adviser or solicitor, since the right approach depends on the owner’s residence history, domicile, and the value and structure of the wider estate.
How This Fits With Other Non-Resident Property Taxes
Inheritance Tax is only one of four separate UK tax charges that apply specifically to non-resident owners of UK property. It sits alongside the stamp duty surcharge paid on purchase, capital gains tax paid on sale, and ATED, the annual charge on property held through a company. Buyers structuring a purchase should look at all four together rather than in isolation, since the ownership structure that reduces one charge can increase exposure to another.
Frequently Asked Questions
Do non-residents pay UK inheritance tax on UK property?
Yes. UK situated property is always within the scope of UK Inheritance Tax on the owner’s death, regardless of the owner’s residence or domicile status.
What changed with inheritance tax for non-residents in 2025?
From 6 April 2025, HMRC replaced the domicile test with a residence based test. An owner who has been UK resident for 10 of the previous 20 tax years has their worldwide estate brought into scope, not just their UK property.
Does holding UK property through an offshore company avoid inheritance tax?
No, not since 6 April 2017. The value of an offshore company’s shares attributable to UK residential property is brought back into the UK Inheritance Tax charge on a chargeable event such as death.
How long do executors have to pay UK inheritance tax?
Payment is generally due six months after the end of the month of death, with interest applying after that date. HMRC offers an instalment option for property, spreading payment over 10 years.
Can double taxation on inheritance be avoided?
Sometimes. The UK has estate tax treaties with a limited number of countries, including the United States and France, which can allow tax paid in one country to be credited against the other. This needs to be checked case by case with a tax adviser.
How much inheritance tax do non-residents pay on a 4m pound UK property?
Around 1,470,000 pounds in the standard case: 4,000,000 pounds minus the 325,000 pound nil rate band leaves 3,675,000 pounds taxable at 40 percent. An 8,000,000 pound property produces a bill of around 3,070,000 pounds on the same basis. A mortgage reduces the bill, since IHT is charged on net equity.
What did the 2025 rule changes do to non-resident inheritance tax?
From 6 April 2025, domicile was replaced with a residence test: owners who were UK resident for 10 of the previous 20 tax years are long-term residents with worldwide assets in scope. A tail of three to ten years applies after leaving, and non-UK trust assets are only sheltered while the settlor is not a long-term resident.
I bought through an offshore company before 2017, is the property still protected?
No. Since 6 April 2017 HMRC looks through the company and taxes the UK residential property value on death, and the 2025 reforms did not restore the shelter. Have the structure reviewed, since de-enveloping can trigger capital gains tax and stamp duty land tax.
What is the long-term residence tail for inheritance tax?
A former long-term resident stays within the UK IHT net for between three and ten years after leaving the UK, depending on how many of the previous 20 years were spent UK resident. During the tail, worldwide assets remain in scope.
Does the 325,000 pound nil rate band apply to non-residents?
Yes. Every individual gets the 325,000 pound nil rate band against UK taxable assets regardless of residence, and unused allowance can transfer between spouses, potentially doubling it to 650,000 pounds.
Does a mortgage reduce the inheritance tax bill on UK property?
Yes. IHT is charged on the net value of the estate, so an outstanding mortgage is deducted from the property value before the 40 percent rate is applied. A 4,000,000 pound property with a 1,500,000 pound mortgage is taxed on 2,500,000 pounds, not 4,000,000.
