You've done the hard part. You found your dream retirement villa in Spain, Portugal, Thailand, or wherever the sun calls you. You've navigated visas, foreign conveyancing, and probably a few moments of "are we really doing this?" But here's a question most UK expats don't ask until it's too late: what happens to that villa when you're gone?
The reality of IHT on overseas property for UK expats catches many families off guard. HMRC doesn't care that your villa is 2,000 miles from London — if you're UK domiciled, your worldwide assets are in scope. And the country where the property sits may want its slice too.
This guide cuts through the jargon to explain exactly how inheritance tax works on foreign villas, what strategies actually work in 2026, and how to make sure your family inherits the paradise you built — not a tax headache.
The £325,000 Trap
The UK IHT nil-rate band has been frozen at £325,000 since 2009 and stays frozen until at least April 2028. With property inflation, many UK expats now find their overseas villa alone pushes their estate well above the threshold — before you even count UK pensions, savings, or investments. At 40% tax on everything above the threshold, the bill can be devastating.
How UK IHT Rules Apply to Expat Property
First, the basics. The UK IHT rules for expat property hinge on one concept that trips everyone up: domicile. Not where you live. Not where you pay tax. Where HMRC considers your permanent home to be.
If you were born in the UK and grew up here, you have a UK domicile of origin. Moving abroad doesn't automatically change that. You'd need to demonstrate a clear, permanent break — selling your UK property, cutting UK ties, and establishing a genuine new permanent home elsewhere. Even then, HMRC can challenge it.
The Domicile Test — Key Factors
Under 2026 rules, even if you successfully acquire a domicile of choice abroad, there's a catch: the "deemed domicile" rule. If you've been UK resident for 15 of the last 20 tax years, HMRC treats you as UK domiciled for IHT purposes regardless. And from April 2025, the government introduced a new 10-year "IHT tail" — meaning you remain in scope for UK IHT for a full decade after leaving, even if you've genuinely emigrated.
Bottom Line
Most UK retirees buying a villa in Spain, Portugal, Greece, or Thailand will remain UK domiciled for IHT purposes. That means your worldwide estate — including your inheritance tax on a foreign villa — is subject to UK IHT at 40% above the nil-rate band.
The Double Taxation Problem
Here's where it gets really uncomfortable. Many countries where UK expats buy retirement property also charge their own version of inheritance or succession tax. So your family could face a bill from HMRC and the country where the villa sits.
| Country | Local Inheritance Tax | UK Double Tax Treaty? | Key Risk |
|---|---|---|---|
| Spain | 7.65%–34% (varies by region) | ✅ Yes | Forced heirship rules may override your will |
| Portugal | 10% stamp duty on inheritances | ❌ No | No treaty = potential double charge |
| France | 5%–45% (depends on relationship) | ✅ Yes | Very high rates for non-direct heirs |
| Italy | 4%–8% (with generous allowances) | ✅ Yes | Forced heirship for children |
| Greece | 1%–40% (depends on relationship) | ❌ No | Complex probate process |
| Thailand | 5%–10% above ≈£2.5m | ❌ No | Foreign ownership structures complicate transfer |
Where a double taxation treaty exists (like with Spain, France, and Italy), you generally get credit for tax paid locally against your UK IHT bill. So you shouldn't pay twice on the same property — but the total tax is effectively the higher of the two rates. Without a treaty (Portugal, Greece, Thailand), unilateral relief may apply, but it's less certain and you'll need specialist advice.
IHT Allowances You Can Actually Use
Before you panic, let's look at the allowances available. Understanding these is the foundation of any sensible estate planning for a retirement home abroad.
Nil-Rate Band
£325,000
The standard tax-free threshold. Frozen since 2009 and until at least 2028.
Residence Nil-Rate Band (RNRB)
£175,000
Additional allowance when passing your main residence to direct descendants. But does it apply to your overseas villa?
Spouse Exemption
Unlimited
Transfers between spouses/civil partners are completely IHT-free. The surviving spouse inherits the unused nil-rate band too.
Combined Couple Allowance
Up to £1m
A married couple can potentially shield up to £1 million (£325k + £175k RNRB × 2) — but only if the RNRB applies.
The RNRB Trap for Overseas Villas
The Residence Nil-Rate Band only applies to property that qualifies as your residence, passed to direct descendants. If you've sold your UK home and your only property is overseas, there's a genuine question about whether RNRB applies.
HMRC's guidance suggests overseas property can qualify — but only if it was genuinely your residence. A holiday villa you visit occasionally won't count. Your main overseas home where you live permanently should qualify, but get specialist confirmation.
Strategies for Passing On Your Overseas Villa to Family
Now for the part you actually came for. If you're serious about passing on your overseas villa to family without them facing a crippling tax bill, these are the approaches that work in 2026.
1Gifting During Your Lifetime
The simplest approach: give the property away while you're alive. If you survive 7 years after the gift, it falls out of your estate entirely. Between 3–7 years, taper relief reduces the IHT bill progressively.
| Years Before Death | IHT Rate on Gift |
|---|---|
| 0–3 years | 40% (full rate) |
| 3–4 years | 32% |
| 4–5 years | 24% |
| 5–6 years | 16% |
| 6–7 years | 8% |
| 7+ years | 0% (exempt) |
The catch: If you continue to live in or benefit from the property after gifting it, it's a "gift with reservation of benefit" and stays in your estate for IHT. You'd need to pay a full market rent to the new owner or move out completely.
2Life Insurance to Cover the Bill
Not glamorous, but extremely effective. A whole-of-life insurance policy written into trust can provide your beneficiaries with the cash to pay the IHT bill — without the payout itself being taxed.
3Trusts — Powerful but Complex
Putting your overseas villa into a trust can remove it from your estate, but UK tax law has made this progressively harder. Discretionary trusts face an immediate 20% entry charge on values above the nil-rate band, plus 10-year periodic charges.
That said, trusts remain useful for specific situations — particularly where the property is held in a corporate structure (common in Thailand) or where you want to control how the asset passes down through generations.
Expert tip: For Thai properties held through a limited company, the trust can hold the company shares rather than the property directly — potentially simplifying both IHT and local succession issues.
4Pension Drawdown and IHT
Since April 2027, unused pension funds will fall within your estate for IHT purposes. This is a significant change. Previously, pensions sat outside IHT — making them an efficient way to pass wealth.
The strategic implication: it may now make more sense to spend your pension on living costs and preserve non-pension assets that benefit from other reliefs. Or alternatively, draw pension to fund the villa purchase and gift other assets. Work with a cross-border expat wealth adviser to model the optimal drawdown strategy for your expat retirement budget 2026.
5Joint Ownership with Your Spouse
Transfers between spouses are IHT-free, and the surviving spouse inherits the unused nil-rate band. Owning the villa jointly (as tenants in common, not joint tenants) gives you flexibility in how each half is distributed.
By leaving each spouse's share to children (with a life interest for the surviving spouse), you can use both nil-rate bands while ensuring the surviving partner can continue living in the property. This is basic estate planning for a retirement home abroad but surprisingly few expat couples set it up properly.
Country-Specific Traps to Watch Out For
🇪🇸 Spain — Forced Heirship
Spanish law traditionally forces you to leave at least two-thirds of your estate to your children, regardless of what your will says. Under EU Regulation 650/2012, UK nationals could elect for English law to govern their succession — but post-Brexit, this is murkier. Get a Spanish lawyer to draft a complementary Spanish will covering your Spanish assets. Learn more in our Spain buying guide.
🇫🇷 France — SCI Structures
Many UK buyers hold French property through a Société Civile Immobilière (SCI). This converts real estate into shares, which can be gifted progressively with generous French tax-free allowances (€100,000 per child every 15 years). The SCI also avoids French forced heirship rules and simplifies probate.
🇹🇭 Thailand — Company Structures
Most UK expats hold Thai villas through a Thai Limited Company. When the owner dies, the company shares need to be transferred — which involves both UK probate (for IHT) and Thai corporate procedures. Planning ahead is essential. See our Thailand villa buying guide for details on ownership structures.
🇵🇹 Portugal — No Treaty, But Low Rates
Portugal charges a flat 10% stamp duty on inheritances — but transfers to spouses, children, and parents are exempt. No UK–Portugal IHT treaty exists, but HMRC may allow unilateral relief. The combination of Portugal's generous exemptions and relatively low rates for non-family transfers means the double-tax risk is lower than it appears.
You Need Two Wills — Not One
This is non-negotiable. If you own property abroad, you need a will in the UK covering your UK assets and a separate will in the country where the villa is located covering the foreign property. Crucially, these wills must not accidentally revoke each other — which happens more often than you'd think.
Do
- Get each will drafted by a lawyer qualified in that jurisdiction
- Ensure each will specifies it only covers assets in that country
- Keep both wills updated when circumstances change
- Consider a letter of wishes alongside each will
Don't
- Assume your English will covers overseas property
- Use a generic "I revoke all previous wills" clause in either will
- Rely on intestacy rules — they vary wildly between countries
- Assume your spouse automatically inherits — some countries require specific provisions
Real-World Example: What Happens Without Planning
John and Margaret, both 72, from Surrey. They retired to a €400,000 villa in Andalusia in 2021. John passed away in 2025 without a Spanish will. His English will left everything to Margaret.
What happened next: because Spain had no record of the English will, probate was delayed by 14 months. The local authorities initially applied Spanish forced heirship rules, potentially requiring a share to go to the couple's adult children. Margaret couldn't sell or remortgage the property during this time. Legal fees exceeded €18,000.
Eventually, the English will was accepted under EU regulation (grandfathered pre-Brexit). But the stress, cost, and delay were entirely avoidable with a €500 Spanish will.
How Much Could Your Family Owe? A Quick Calculation
Let's put numbers to it. For a single person (or the surviving spouse scenario) with a £400,000 overseas villa and other UK assets, here's the picture. Understanding the funding for overseas property purchase pension and overall estate value together is essential.
| Asset | Single Person | Married Couple |
|---|---|---|
| Overseas Villa | £400,000 | £400,000 |
| Pensions (post-April 2027) | £200,000 | £350,000 |
| Savings & Investments | £150,000 | £250,000 |
| Total Estate | £750,000 | £1,000,000 |
| Less: Nil-Rate Band(s) | (£325,000) | (£650,000) |
| Less: RNRB (if applicable) | (£175,000) | (£350,000) |
| Taxable Estate | £250,000 | £0 |
| IHT at 40% | £100,000 | £0 |
The married couple example shows zero IHT — but only if the RNRB applies to the overseas villa (which requires it to be your main residence passed to direct descendants). Without RNRB, their taxable estate jumps to £350,000 with an IHT bill of £140,000.
