Buying a property abroad while remaining UK resident is one of the most common financial decisions British internationally minded individuals make — whether for holidays, retirement planning, or investment income.
The tax implications are significant and frequently misunderstood. Too many buyers focus on the purchase price and ignore the ongoing and future tax position, only to encounter surprises when they come to let the property, sell it, or pass it on.
Stamp Duty Land Tax (SDLT): The Surcharges
SDLT is a UK tax on property purchases — but it applies to all property purchases by UK residents, including overseas property? No — that is the most important clarification first:
SDLT applies only to properties located in England and Northern Ireland. It does not apply to property purchased in Spain, France, Cyprus, or anywhere outside England/Northern Ireland. Your foreign property purchase will be subject to the equivalent purchase tax in the country of purchase (notarial taxes, transfer taxes, VAT where applicable), but not UK SDLT.
However, SDLT on any UK property you own or purchase in future is affected by overseas property ownership in one important way: the additional dwelling surcharge.
If you purchase a UK property and already own (or are purchasing) another property anywhere in the world — including your overseas holiday home — you may be subject to the SDLT additional dwellings surcharge of 5% (as of 2025). This applies because overseas property counts when determining whether you own multiple dwellings.
Example: You own a house in Bristol. You buy a holiday apartment in Málaga in April 2025. Three years later, you decide to buy a buy-to-let property in Manchester. When you purchase the Manchester property, you own two properties (Bristol + Málaga), making the Manchester purchase a "third property" acquisition subject to the additional dwelling surcharge.
The surcharge applies on the total purchase price. On a £300,000 Manchester flat, this could add £15,000 to your SDLT bill compared with a first-time purchase.
Capital Gains Tax (CGT) on Disposal
When you sell your overseas property, UK CGT applies to any gain — because as a UK resident, you are taxable on worldwide capital gains.
The calculation:
- Gain = Sale proceeds (net of selling costs) minus purchase price (plus purchase costs) minus any qualifying improvement costs
- The gain must be converted to GBP at the exchange rate applicable on the date of each transaction (purchase and sale)
- Annual CGT exempt amount: £3,000 (2026/27 — significantly reduced from its historical level)
- Rates: 18% (basic rate taxpayer) or 24% (higher/additional rate taxpayer) on residential property gains
Indexation allowance: was abolished for individuals in 1998. You cannot adjust your gain for inflation. If you hold a property for 20 years and it doubles in sterling terms while inflation has also roughly doubled, you pay CGT on the nominal gain, not the real gain.
Private Residence Relief (PRR): If the overseas property has been your main residence at any point, you may be entitled to partial PRR to reduce the gain. This requires the property to genuinely have been your only or main residence — claiming a Spanish holiday apartment as your main residence while living in Bristol will not succeed and constitutes a false declaration to HMRC.
Reporting: CGT on overseas property disposals must be reported on your UK self-assessment tax return. Unlike UK residential property, there is no 60-day reporting requirement for overseas property — it is reported in the normal self-assessment cycle.
Rental Income: Taxable in Two Countries
If you let your overseas property — even for short periods — the rental income is generally taxable in:
The country where the property is located — most countries tax rental income from properties within their territory. This is often levied at a flat withholding rate for non-residents.
The UK — as a UK resident, your worldwide income is taxable in the UK, including overseas rental income.
Double taxation treaties prevent you from being taxed twice on the same income. Most of the UK's bilateral DTTs include provisions on rental income from overseas property. Typically:
- The country where the property is located has the primary taxing right on rental income
- The UK allows a credit against UK tax for the overseas tax already paid
- You pay the higher of the two rates, not both rates in full
Example (Spain): Spanish rental income is subject to Spanish non-resident property tax (IRNR). The rate is 19% for EU/EEA residents, but 24% for residents of countries outside the EU/EEA — including the UK following Brexit. Under the UK-Spain DTA, you credit this against UK income tax. If you are a UK higher-rate taxpayer (40%), you credit the 24% paid in Spain against your 40% UK liability — effectively paying 24% to Spain and the remaining 16% to HMRC.
The allowable deductions for UK purposes:
UK rental income rules allow deductions for:
- Mortgage interest — but note the Section 24 restriction. Mortgage interest on residential property owned by individuals is not fully deductible — you receive a 20% tax credit (basic rate) rather than a full deduction. This applies to overseas residential property as well as UK residential property.
- Letting agent fees, management costs
- Repairs and maintenance (not improvements)
- Travel costs to the property for management purposes (within limits)
- Insurance
Overseas Property and Inheritance Tax
This is where many British buyers are surprised. UK inheritance tax is levied on the worldwide estate of UK domiciliaries (individuals who consider the UK their permanent home). If you are UK domiciled — which most British nationals are — your overseas property forms part of your estate for IHT purposes.
The IHT position:
- Overseas property is included in your estate at its market value (in GBP at the date of death)
- UK IHT (40% above the nil rate band and any residence nil rate band allowance) applies on the aggregate estate including overseas property
- The IHT nil rate band is £325,000 per person; the residence nil rate band adds up to £175,000 where a UK residential property passes to direct descendants
- If you also pay an overseas inheritance-equivalent tax in the country where the property is located, double tax relief may be available
Spain example: Spain has its own impuesto sobre sucesiones y donaciones (inheritance and gift tax). Under the UK-Spain Estate Tax DTA, relief from double taxation is available so the same asset is not taxed fully in both countries. However, Spanish inheritance tax is paid first and credited against UK IHT — the administrative burden is significant.
Mitigation strategies:
- Married couples can hold overseas property jointly — the first death triggers a spousal exemption from UK IHT (if the surviving spouse is UK domiciled)
- Non-domicile status and the remittance basis were abolished on 6 April 2025 and replaced by the four-year Foreign Income and Gains (FIG) regime for new arrivers; IHT is now residence-based. These changes significantly reduce the historic non-dom IHT planning options for most individuals
- Offshore corporate structures have historically been used but have been progressively targeted by HMRC anti-avoidance rules
- Life insurance to fund the IHT bill — a practical and common solution for property-heavy estates
Using a Company Structure
Some buyers consider purchasing overseas property through a company structure — either a UK company or an overseas company. This has potential advantages and significant disadvantages.
Potential advantages:
- Rental income taxed at corporate rate (25% UK corporation tax) rather than income tax (up to 45%)
- Capital gains on disposal taxed at corporate rate
- Potential IHT advantages — shares in a company are generally not treated as UK situs assets even if the company owns UK property, although this has been progressively targeted
Significant disadvantages:
- Running a company has ongoing costs: accounting, company secretarial, filing obligations
- HMRC has extensive anti-avoidance rules targeting offshore structures designed to reduce UK tax
- Extracting income from the company as a UK resident director has its own tax implications
- Mortgage finance through a company is generally more expensive and harder to arrange
- ATED (Annual Tax on Enveloped Dwellings) applies to UK residential property held in a company worth over £500,000 — the ATED charge escalates with property value
For overseas property specifically (outside the UK), the company structure analysis is different from UK property in a company. Advice from a tax specialist before purchasing is essential — the structure must be chosen before the purchase, not retrofitted afterwards.
The Currency Dimension
Buying overseas property as a UK resident involves an exchange of GBP for the local currency at some point, and a reverse conversion when selling (unless you reinvest proceeds locally). The currency exposure is significant:
- A 10% appreciation of EUR against GBP increases the GBP value of your Spanish property by 10% — even if its local currency value is unchanged
- A 10% depreciation does the opposite
Currency impact on CGT:
The gain for UK CGT purposes is calculated in GBP. If you bought a Spanish apartment for €300,000 when GBP/EUR was 1.30 (cost £230,769) and sold it for €350,000 when GBP/EUR was 1.10 (proceeds £318,182), your gain in GBP is £87,413 — even though the property only appreciated by €50,000 in local terms. The currency movement has increased your UK CGT liability.
Conversely, if sterling had strengthened, currency movement could eliminate a local currency gain in GBP terms, leaving you with a CGT liability but feeling like you have not made money.
Practical Examples by Country
Spain
Spain is the most popular destination for UK overseas property buyers. Key taxes:
- Purchase: ITP (Impuesto de Transmisiones Patrimoniales) — transfer tax on existing properties, currently 6–10% depending on region; IVA (VAT) 10% on new properties
- Annual holding: IBI (local property tax); IRNR declaration (non-resident income tax — even if not letting, a deemed income of 1.1–2% of catastral value is assessed annually)
- Rental income: IRNR at 24% for UK residents (non-EU rate; 19% applies to EU/EEA residents only)
- Capital gain: Spanish CGT at 24% flat for UK residents (non-EU rate; 19% for EU/EEA residents)
- UK position: All as described above — CGT, rental income reporting, IHT
France
France has a comprehensive property transaction and holding tax regime. Notaire fees at purchase (approximately 7–8% of purchase price for existing property). Taxe foncière (property tax) annually. CGT at 19% plus social charges (17.2%) for non-residents — subject to DTA credit in UK.
Cyprus
Cyprus has historically been attractive for UK buyers. No property-level wealth tax; acquisition costs lower than France or Spain; the UK-Cyprus DTA is well-established. Capital gains tax in Cyprus applies on gains from Cyprus property at 20%.
Italy
Italy charges registration tax (2–9% depending on circumstances), plus cadaster and mortgage registration fees. Rental income subject to Italian cedolare secca flat tax option at 21%. Strong DTA with UK.
Key Action Points Before Buying
Get tax advice in both countries before purchase — from a UK adviser and a local adviser. The structure and ownership name must be decided before notarisation.
Understand your annual running tax obligations — IRNR in Spain, taxe foncière in France, IBI everywhere.
Plan for rental income compliance from day one if you intend to let — both local and UK reporting.
Consider the IHT position and whether life insurance or joint ownership structure is appropriate.
Set up a dedicated FX strategy for purchase, rental income, and eventual sale — using a specialist FX broker rather than your bank for large transactions.
