If you’re living in the UK and thinking about selling property overseas, the first question is almost always the same: Do I have to pay capital gains tax in the UK on it? The short answer is yes, usually.
HMRC looks at:
- Your residence status
- The type of property
- The gain you’ve made
From there, they work out what portion belongs to the UK. The long answer takes more explaining, because overseas property sales can trigger tax both where the property sits and back home in Britain, which is why people quickly want to know about double taxation agreements and reliefs.
KEY FACTS AT A GLANCE
- Who pays: UK tax residents pay UK CGT on overseas property gains, regardless of where the property sits.
- Rates from 6 April 2026: 18% within your basic Income Tax band, 24% above it (residential and non-residential aligned since the October 2024 Budget).
- Annual Exempt Amount: £3,000 per individual (£6,000 if you own jointly).
- Reporting route: Self Assessment (SA108 + SA106), deadline 31 January after the tax year of the sale. The 60-day rule does not apply to overseas property — only to UK residential property.
- Double taxation relief: Foreign Tax Credit Relief offsets tax already paid in the property country under HMRC’s treaty network.
- PRR may apply if the overseas property was genuinely your main residence for part of the ownership period.
Do You Pay Capital Gains Tax on Overseas Property?
If you’re a UK resident and you sell an overseas asset, HMRC will want to know. That includes everything from second homes in Spain to rental flats in Dubai. The basic principle is straightforward: you’re taxed on your worldwide gains if you live in the UK. Non-residents have different rules, but if you’re reading this with a UK address, then the gains count.
That doesn’t mean you’ll be taxed twice without relief. Double taxation agreements step in to avoid that. Say you sell in Portugal, where there’s local tax on the gain. If there’s a treaty, the UK recognises that tax and allows credit, so you don’t end up paying both countries in full. HMRC publishes the agreements, and you can check them online before you sell.
If you’re reading this before you’ve bought, you’re ahead of most foreign buyers — who only think about CGT when they’re about to sell. The decisions made at purchase (country, joint vs solo, mortgage size, deposit structure) all change the eventual CGT bill years down the line.
Structure decisions made before you buy determine what you’ll owe when you sell. Get pre-approved before you commit to a country.
What Counts as a Taxable Gain?
To work out a taxable gain, you start with the sale price, deduct the costs (purchase price, improvements, selling fees), and then see what’s left. The gap between those two figures is your gain.
So it’s simple in concept but fiddly when you’re actually doing it because foreign exchange rates matter: HMRC wants figures converted into sterling at the correct rate, not whatever your bank showed on transfer day.
If you’ve owned the property for years, you’ll also want to dig up completion statements and any legal fees to keep your taxable gain as low as possible.
Allowable acquisition costs (added to the purchase price to reduce your gain) include legal and notary fees, the transfer tax equivalent in the property country (ITP in Spain, IMT in Portugal, DLD fee in UAE), survey fees, mortgage arrangement fees, and capital improvements that materially increase the property value (extensions, kitchens, roofs) — routine maintenance and redecoration do not count.
Allowable disposal costs (deducted from the sale price) include estate agent commissions, legal fees for the sale, advertising costs, and costs of valuations required for the sale.
Keep every receipt. HMRC accepts professional documents in the original language with a sworn translation if requested.
What Are the UK CGT Rates on Overseas Property in 2026-27?
For tax year 2026-27 (gains realised from 6 April 2026 onwards), the UK CGT rates on overseas property are:
| Your Income Tax band | Rate on overseas property gain |
|---|---|
| Basic rate (income up to £50,270) | 18% (within the basic band) |
| Higher rate (income £50,271–£125,140) | 24% |
| Additional rate (income above £125,140) | 24% |
| Trustees and personal representatives | 24% |
The rates apply to both residential and non-residential property. This is a change from the pre-October 2024 framework, when non-residential gains were taxed at 10% / 20% while residential sat at 18% / 28%. The Autumn Budget 2024 aligned the rates for non-residential at 18% / 24% effective 30 October 2024, while the residential higher rate was reduced from 28% to 24%. From 6 April 2026, the table above applies cleanly across both asset types.
Annual Exempt Amount in 2026-27: £3,000 per individual, or £6,000 for jointly-owned property. The AEA was £12,300 in 2022-23 and £6,000 in 2023-24 — the reduction to £3,000 from April 2024 onwards means structuring decisions (joint title, timing across tax years, loss harvesting) are materially more valuable than they used to be.
How Does Currency Conversion Affect Your CGT?
HMRC assesses your gain in pounds sterling, not in the currency of the property country. You convert the purchase price into GBP at the exchange rate on the day you bought, and the sale price into GBP at the rate on the day you sold. Both conversions use the rate of the specific transaction date, not an annual average.
This creates a phenomenon foreign buyers are often surprised by: currency moves can create a taxable UK gain even when the property barely appreciated in the property country’s currency. A real-world numeric example, from a UK seller posting in r/UKPersonalFinance:
“If you received the property 3 years ago when it was worth $123,000 and the exchange rate was 90¢ to £1 and it was worth $156,000 when you dispose of it when the exchange rate is 75¢ to £1 then your capital gain for tax purposes is (156 × 0.75) − (123 × 0.9) = £6,300.”
The same principle works in reverse for UK buyers in the EU: a property bought in 2018 at €200,000 (when £1 ≈ €1.16) and sold in 2026 at €230,000 (when £1 ≈ €1.20) shows an apparent €30,000 EUR gain but only a £18,900 GBP gain — because the pound strengthened against the euro. If the pound had weakened, the GBP gain would have exceeded the EUR gain. The currency exposure is in addition to the property exposure, and it can dominate over short holding periods or in volatile currencies.
HMRC accepts either spot rates (the actual rate on the day) or HMRC’s monthly exchange rates, applied consistently. Keep evidence of the rate you used.
HEADS UP
The FX dynamic at sale time can convert a winning property into a flat-return one — or worse, a CGT bill on a ‘paper gain’ from currency moves. Most UK buyers don’t account for this when sizing the mortgage. Among more than 1,000 UK buyers tracked by Upscore, the typical hold is 5–15 years — long enough for FX exposure to compound materially. Planning the GBP-equivalent return at purchase is part of our pre-approval analysis. Before you commit to a country, see how the eventual CGT exit affects the all-in cost.

How Do You Calculate CGT on Overseas Property — Step by Step
Below is the worked HMRC method. The example uses a UK resident selling a Spanish villa in 2026.
Worked example — UK resident sells a villa in Alicante, Spain:
| Step | Calculation | Amount |
|---|---|---|
| 1. Sale price in EUR | Sale agreed in 2026 | €280,000 |
| 2. Sale price in GBP | × 0.84 GBP/EUR rate at sale | £235,200 |
| 3. Disposal costs (agent + legal) | Converted at the same date | £8,400 |
| 4. Net sale proceeds | £226,800 | |
| 5. Purchase price in EUR (2018) | €180,000 | |
| 6. Purchase price in GBP | × 0.88 GBP/EUR rate at purchase | £158,400 |
| 7. Capital improvements (2020 renovation) | Converted at 2020 rate | £13,200 |
| 8. Notary + ITP at purchase | £14,500 | |
| 9. Total acquisition costs | £186,100 | |
| 10. Gross gain | (4) − (9) | £40,700 |
| 11. Annual Exempt Amount | 2026-27 | (£3,000) |
| 12. Taxable gain | £37,700 | |
| 13. Apply CGT rate | At 24% (higher rate taxpayer) | £9,048 |
| 14. Less Foreign Tax Credit (Spanish IRNR 19% paid locally) | (£7,163) | |
| 15. Net UK CGT due | £1,885 |
The 9-step procedure (HowTo schema-ready):
- Work out the sale proceeds in sterling using the exchange rate on the completion date.
- Deduct selling costs (agent fees, legal fees) converted at the same date.
- Work out the acquisition cost in sterling using the exchange rate on the purchase date.
- Add allowable acquisition costs (legal fees, transfer tax, capital improvements), each converted at the rate of its own transaction date.
- Subtract total acquisition cost from net sale proceeds to get your gross gain.
- Apply your Annual Exempt Amount (£3,000 for 2026-27).
- Add the taxable gain to your taxable income to determine the Income Tax band.
- Apply the correct CGT rate — 18% within the basic band, 24% above.
- Claim Foreign Tax Credit Relief if applicable, and complete SA108 (Capital Gains summary) plus SA106 (Foreign pages) on your Self Assessment return.
How to Report Overseas Property Gains to HMRC
Reporting an overseas property sale goes through your Self Assessment tax return. You must:
- Complete the capital gains summary form (SA108)
- Complete the Foreign pages (SA106) to claim any Foreign Tax Credit Relief
- List the details (acquisition date, disposal date, costs, gain, foreign tax paid)
- Submit online by 31 January after the tax year of the sale
Selling overseas assets can trigger the requirement to file Self Assessment even if you don’t usually file one. Don’t ignore it — penalties for late reporting and late payment add up fast. HMRC expects clear records:
- Completion dates
- Exchange rates
- Cost bases
- Evidence of any tax you paid abroad
Keep those documents organised, because they may be requested.
The structure you set up at the mortgage stage — country, joint ownership, deposit split — is what your accountant will work with at sale time.
HEADS UP A UK
property sold by a UK resident triggers a separate 60-day Capital Gains Tax on UK Property return — that’s the standalone online service most people have heard of. This obligation does not apply to overseas property. Overseas sales go through Self Assessment, with the standard 31 January deadline. You’ll see plenty of advice online (including some confidently-written Reddit comments and even some accountant blogs) that conflates the two — they’re separate routes.
If you’re a UK non-resident selling UK residential property, the 60-day rule does apply to you. The asset location, not your status alone, drives the route.
What Reliefs and Exemptions Can Reduce Your CGT?
Several reliefs can reduce or eliminate your CGT bill on an overseas sale.
Annual Exempt Amount
Everyone gets an annual £3,000 exemption for 2026-27. You apply it to your total taxable gains across the tax year before applying the rate. It’s not transferable — unused allowance does not carry forward.
Private Residence Relief (PRR) on Overseas Property
PRR is the relief that eliminates CGT on the sale of your main home. The headline rule is the same as for UK property: the proportion of your ownership period during which the property was genuinely your only or main residence is exempt from CGT.
PRR on overseas property is technically available, but harder to claim than on UK property. Since 2015, there has been a 90-day occupancy test for each tax year — you need to have stayed in the overseas property at least 90 nights in the relevant tax year for it to qualify as your residence for that year. This rule (section 222B of TCGA 1992) catches buyers who own the property but only visit it for shorter holidays.
If you owned both a UK property and an overseas property, you could elect which was your main residence within two years of buying the second. If you never made that election, HMRC will decide based on evidence — typically utility usage, presence of personal possessions, and time spent in each.
Foreign Tax Credit Relief (Double Taxation Relief)
If the property country also charged CGT on the sale, you can claim Foreign Tax Credit Relief on your UK return. The relief is limited to the lower of:
- The UK tax due on the gain, or
- The foreign tax actually paid on the same gain
This eliminates double taxation but does not refund the higher of the two — if you paid more abroad than the UK would charge, the excess is lost. Keep proof of the foreign tax assessment, payment receipts, and translations where requested.
Capital Losses
Any capital losses you realised in the same tax year (UK or overseas) can be offset against the gain on the overseas property. Unused losses carry forward indefinitely to future tax years, provided you report them on Self Assessment in the year they were realised. This is a powerful planning tool — selling a loss-making investment in the same tax year as the property sale can materially reduce the UK CGT bill.
Joint Ownership
If the property is owned jointly, each owner has their own £3,000 AEA, their own CGT rate band, and their own Foreign Tax Credit Relief eligibility. Joint ownership effectively doubles the tax-free portion of the gain and can keep some of the remaining gain within the basic 18% band even when one spouse is a higher-rate taxpayer.
HEADS UP
About 30% of UK buyers in Upscore’s customer base purchase jointly — and one of the often-missed reasons it makes sense is that joint owners double the £3,000 AEA at sale time. The decision joint-vs-solo title is made at the mortgage stage, not at the sale stage. Once the deed is in one name, splitting it later triggers its own tax events (a transfer between spouses is exempt only in narrow circumstances and the rules tightened post-divorce).
Spousal transfers and timing across tax years
Transfers between spouses or civil partners (both UK resident, living together) are made on a “no gain, no loss” basis, which lets you balance a gain between two tax bands or use both AEAs even on a solely-owned property — provided the transfer is genuine and happens before the sale. Where the disposal can be structured around a tax year boundary (e.g., portfolios sold in parts), spreading across two tax years gives two £3,000 AEAs and two opportunities to use the basic-rate band.
How Does Double Taxation Work With Spain, Portugal, France and UAE?
The four countries where the most UK buyers concentrate each have a different CGT regime locally and a different treaty mechanic with the UK. Upscore’s mortgage products focus on Spain for UK buyers and Portugal for UK buyers, the two largest segments in our customer base.
| Country | Local CGT rate (non-resident seller) | UK treaty | Mechanic |
|---|---|---|---|
| Spain | 19% IRNR on the gain | UK-Spain Double Taxation Convention 1976 | Pay Spain 19% on the gain. Claim FTCR on UK return. UK collects the difference if UK CGT is higher. |
| Portugal | 28% on 50% of the gain for non-residents (effective ~14%); residents pay marginal IRS rates Cat G | UK-Portugal Convention 1968 | Pay Portugal first. Claim FTCR. |
| France | 19% plus social charges (prélèvements sociaux 17.2% — UK residents are exempt from social charges if not affiliated to French social security) | UK-France Convention 2008 | UK residents typically pay only the 19% portion in France, then claim FTCR in the UK. |
| UAE | No CGT on the gain | UK-UAE Treaty 2016 | UAE doesn’t tax the gain, so there’s no FTCR to claim. The full UK CGT applies. |
The treaty doesn’t make tax disappear — it just stops you paying twice on the same gain. You effectively pay the higher of the two rates: if Portugal taxes the gain at 14% effective and the UK at 22%, you pay Portugal first, claim the credit on your UK return, and top up the £2,000 difference in the UK.
HEADS UP
The UK-Spain treaty mechanics vs UK-Portugal vs UAE (no CGT) materially change the all-in tax cost of the eventual sale. Among Upscore’s UK customer base, Spain takes 43%, Portugal 34%, UAE 19% of buyers — and the CGT differential between these three countries is one factor (alongside mortgage availability, deposit requirements and lifestyle) that determines which country a buyer should consider. Our pre-approval process surfaces this trade-off before you commit to a country. Already own overseas and considering selling?

How Does HMRC Know About Foreign Property?
HMRC has multiple channels of information about overseas assets owned by UK residents. The most material is the Common Reporting Standard (CRS): more than 100 countries automatically share financial account data with HMRC each year, including balances and beneficial owners. If you opened a Spanish or Portuguese bank account to receive rental income or pay the mortgage, HMRC almost certainly has visibility of it.
On top of CRS, large EUR-to-GBP transfers are flagged through the foreign bank’s own AML reporting; land registries (EU plus UAE’s RERA and Dubai Land Department) share property ownership data with HMRC; and if you’ve ever reported rental income from the overseas property on a prior Self Assessment return, HMRC already has the property on file. Letting agents in some jurisdictions report rental flows directly.
The practical implication: if you’ve held overseas property for more than a few years, assume HMRC knows. Reporting the sale correctly through Self Assessment is materially cheaper than a discovery assessment — HMRC’s Worldwide Disclosure Facility carries lower penalties than waiting to be found.
What About UK Residents Moving Abroad?
If you’re moving overseas, the timing of your sale matters. Non-residents may avoid UK capital gains tax on some overseas assets after certain periods of non-residency, but HMRC has strict rules.
What is the 5+ Tax Year Temporary Non-Residence Rule?
Becoming a non-resident for less than five years can result in your gains still being taxed when you return. This “temporary non-residence” rule catches people who thought a quick stint abroad would exempt them: if you sell an asset while non-UK-resident and return to the UK within five complete tax years, the gain is treated as if it arose in the year you returned.
A common misunderstanding is that “five years” means five calendar years from departure. The correct rule is more than five tax years of continuous non-residence — split-year treatment around the departure and return dates means the effective window is closer to “five years and one day” measured continuously.
HEADS UP
Upscore’s UAE-bound UK buyers (197 in our customer base) often relocate temporarily for work. The 5-year+ rule is one of the costliest ‘gotchas’ for this segment — selling during the Dubai stint and returning within five tax years brings the gain back into UK tax. Mortgage structuring for UAE buyers should factor in expected return timing, including refinancing optionality if a longer-than-anticipated stay would change the disposal plan.
Bringing Money to UK After the Sale — Has Anything Changed?
A common worry: “I paid CGT in the property country, I’ll pay UK CGT through Self Assessment — will I be charged again when I transfer the proceeds into a UK bank account?”
For UK domiciled UK residents, the answer is no. Once the UK CGT is settled through Self Assessment (with Foreign Tax Credit Relief applied), the sale proceeds are after-tax money. Transferring them into a UK account does not trigger a fresh tax event. The practical considerations are the FX cost on the transfer itself (which can run into thousands of pounds with a high-street bank versus a specialist FX provider) and AML checks — UK banks may ask for the sale completion statement and proof that CGT was reported, so keep documentation accessible.
For UK residents who were non-UK domiciled, the old remittance basis was abolished from 6 April 2025 and replaced by the Foreign Income and Gains (FIG) regime — a four-year window during which qualifying newcomers can elect for full exemption on foreign income and gains, regardless of whether the funds are remitted. The long-standing planning move of “leave the proceeds in the property country to avoid UK tax on remittance” no longer works. Forum advice that still references the old remittance basis is out of date.
How Upscore Helps UK Buyers Before, During, and After the Sale
Upscore is a mortgage broker for foreign buyers — we sit on the pre-purchase side of the journey, before the property is even owned. We are not tax accountants and we don’t file your CGT return. But the structure decisions made at the mortgage stage materially affect what your eventual CGT bill looks like years down the line.
Before buying. The Finance Passport pre-approval process surfaces decisions with long-term tax consequences: which country to buy in (Spain, Portugal, France, UAE each carry different effective CGT outcomes), joint vs solo title (doubles the £3,000 AEA at sale), mortgage sizing relative to expected hold period (FX exposure compounds over time). For UK buyers, our guide to which UK banks offer overseas mortgages explains why the standard high-street route rarely works for a foreign purchase.
During hold and before sale. A property bought when the pound was weak and held while the pound strengthens is sitting on a UK gain even when nothing has changed in the property country. Buyers planning a sale 12–24 months out can think through restructuring options (timing across tax years, capital improvements recording, spousal transfer where applicable) before triggering the disposal. For the filing itself, we hand off cleanly to UK accountants in our network.
The buyers who do well on the tax side of overseas property are not the ones who hire a great accountant at the moment of sale. They are the ones who got the structure right at the moment of purchase.
Pre-approval that thinks 10 years ahead. Get the structure right at purchase — not at the point of sale.
Frequently Asked Questions
Do I pay UK Capital Gains Tax on overseas property?
Yes, if you are a UK tax resident. UK tax residents pay UK CGT on profits from the sale of overseas property, regardless of whether the property country also taxes the same gain. Double Taxation Relief is available through Foreign Tax Credit Relief if you’ve paid tax in the property country.
How much is UK Capital Gains Tax on overseas property in 2026?
From 6 April 2026, the rates are 18% (within your basic Income Tax band) and 24% (above it). The Annual Exempt Amount is £3,000 per individual, or £6,000 for jointly owned property. The rates apply equally to residential and non-residential overseas property.
Does the 60-day reporting rule apply to overseas property?
No. The 60-day rule applies only to UK residential property. Overseas property sales are reported through Self Assessment (SA108 capital gains summary + SA106 foreign pages), with the standard 31 January deadline after the end of the tax year of the sale.
How does HMRC know I have property abroad?
HMRC receives information through the Common Reporting Standard (CRS), which automatically shares financial data from more than 100 countries each year. Foreign bank accounts, large transfers, land registry data, and any rental income reported on prior Self Assessment returns all flag overseas assets to HMRC.
Can I use Private Residence Relief on an overseas property?
Yes, but only for the proportion of your ownership during which the property was genuinely your main residence. Since 2015, you must have stayed at least 90 nights in the overseas property in a tax year for that year to count under section 222B of TCGA 1992. PRR is therefore harder to claim for an overseas holiday home than for a UK main residence.
Do I pay 18% or 24% on the whole sale price?
No. You pay the rate on the gain, not the sale price. The gain is sale proceeds minus allowable costs (purchase price, capital improvements, transaction fees), minus the £3,000 Annual Exempt Amount. The rate is then applied only to that net taxable gain.
Can I avoid Capital Gains Tax on overseas property legally?
There are legitimate planning moves: claim every allowable cost, use joint ownership to double the AEA, time the sale to use lower-rate band capacity, claim Foreign Tax Credit Relief, claim PRR if eligible, harvest offsetting losses in the same tax year, and consider a spousal transfer before sale. None of these are evasion — they are structuring within the rules. The starting move is to keep complete records from the purchase date onwards.
The Bottom Line
UK residents pay UK CGT on overseas property gains at 18% or 24% from 6 April 2026, with a £3,000 Annual Exempt Amount per individual. Report through Self Assessment (not the 60-day UK property service) by 31 January after the tax year of the sale, and claim Foreign Tax Credit Relief if you’ve already paid tax in the property country. The decisions that most reduce the eventual UK CGT bill — country choice, joint ownership, capital improvements documentation, mortgage structure — are made at the moment of purchase, not at the moment of sale.
