Taxes on Property Abroad: Buying, Owning, Letting and Selling Explained
Overseas property is taxed at four moments: when you buy, every year you own it, whenever you let it and when you sell. Each can be taxed twice, once where the home sits and once where you live. This guide maps the taxes and explains how double tax treaties and credits usually work.
Tax is the part of an overseas purchase buyers tend to discover in instalments: a transfer tax at completion, an unexpected annual bill, a return they did not know they had to file, and finally a withholding at sale. It does not need to be a surprise. Property abroad is taxed at four predictable moments, and at each one you need to ask the same two questions: what does the country where the home sits charge, and what does my home country charge?
Why there are two tax systems
The country where the property is located almost always has the right to tax income and gains from land within its borders. Meanwhile most countries tax their residents on worldwide income, and the United States taxes its citizens wherever they live. So rent and sale profits from a foreign home are often reportable in two places.
Double tax treaties sort this out. Under the standard model used by most treaties, the country where the property sits taxes first, and your home country gives a credit for that tax against its own. You do not pay twice in full, but you may pay the higher of the two rates overall, and you still file in both places. Where no treaty exists, many countries offer unilateral relief on similar lines.
Moment one: buying
Purchase taxes are paid in the country where the property sits, and they are usually the largest single cost after the price itself.
- Transfer tax or stamp duty on resale homes, set nationally or regionally. Spain's transfer tax rate depends on the region; Portugal's IMT is charged on a sliding scale with a separate stamp duty; the UK charges Stamp Duty Land Tax in England and Northern Ireland, with separate taxes in Scotland and Wales.
- VAT on new builds in some countries instead of transfer tax, sometimes with an additional stamp duty on the deed.
- Surcharges for second homes, companies or non-residents. England, for instance, adds surcharges for additional properties and for non-resident buyers.
- Notary, registry and legal fees, which are not taxes but are charged at the same time and often on a scale linked to the price.
Your home country normally does not tax the purchase, but keep every receipt: purchase costs are often deductible when calculating a later capital gain in both countries.
Moment two: owning
Annual taxes continue whether you visit or not.
- Local property tax, set by the municipality on an official assessed value. Examples include the IMI in Portugal, the IBI in Spain, the taxe foncière in France and council tax in the UK.
- Taxes on second homes. France allows communes to charge residence tax on second homes and to raise it in areas with housing shortages. Spain taxes non-resident owners on a deemed income from a home they do not let.
- Wealth or high-value property taxes. Some countries tax high-value real estate holdings each year. Portugal has an additional IMI charge on high aggregate property values, and France taxes high-value real estate wealth through its IFI.
- Home country. Most countries do not tax an unlet foreign home annually, but some require you to declare foreign assets or accounts above set thresholds.
Moment three: letting
Rental income is usually taxable in the country where the home is located, and non-residents often face a flat rate on gross or net income, with deductions that vary. EU and European Economic Area residents in some countries, Spain among them, can deduct expenses that non-EU residents cannot.
You then declare the same income at home, calculated under your home country's rules, and claim a credit for the foreign tax. The two calculations rarely match, because allowable expenses, depreciation and exchange rates differ, so keep records that satisfy both systems.
Holiday lets bring extra obligations: tourist taxes collected from guests, registration numbers and, in some places, VAT on short stays with services.
Moment four: selling
Capital gains tax on a sale is generally charged where the property is located, then reported at home with a credit.
- Withholding. Several countries make the buyer withhold part of the price from a non-resident seller. Spain withholds a percentage of the price for non-resident sellers; the United States applies FIRPTA withholding to foreign sellers. The seller files a return afterwards to settle the actual tax and reclaim any excess.
- Main residence reliefs often do not apply to a second home, or apply only to residents.
- Exchange rates. Some home-country rules calculate the gain in your own currency using the rates at purchase and sale, so a property that made no gain in euros can show a taxable gain, or a loss, in sterling or dollars.
- Local municipal taxes on land value increases, such as Spain's plusvalía, may also apply.
Death and gifts
Inheritance and gift taxes follow their own rules, and treaties on estates are far less common than on income. The country where the property sits may charge inheritance tax, and your home country may too. Plan this separately with a lawyer in each country.
The four moments at a glance
| Moment | Where the home sits | Your home country |
|---|---|---|
| Buying | Transfer tax or VAT, stamp duty, surcharges | Usually nothing; keep records |
| Owning | Local property tax, deemed-income or second-home taxes, wealth taxes | Possible foreign-asset reporting |
| Letting | Tax on rental income, tourist taxes | Declare income, claim credit |
| Selling | Capital gains tax, withholding, local land taxes | Declare gain, claim credit |
| Death | Inheritance or succession tax | Possible inheritance tax |
Owning through a company
Some buyers consider holding foreign property through a company to simplify inheritance or limit liability. The tax effects are rarely neutral. Several countries impose higher purchase or annual taxes on company-owned homes, treat private use by a shareholder as a taxable benefit, or tax companies based in low-tax jurisdictions at punitive rates. Your home country may also tax the company's income as if it were yours. A structure that works well in one pair of countries can be expensive in another, so model the costs in both before choosing.
Keeping it manageable
- Appoint a local tax representative or administrator who files on time, and get copies of every return.
- Tell your home-country adviser about the property in the year you buy, not the year you sell.
- Keep a single folder, physical or digital, with the purchase deed, every invoice for improvements, tax receipts and exchange rates for major payments.
- Read the double tax treaty between the two countries, or ask your adviser for a summary of how it treats property income and gains.
Rates and thresholds change regularly, and each country's tax authority publishes current figures. The structure, though, stays remarkably stable. If you know which tax applies at each of the four moments in both countries, very little about owning abroad will catch you out.
Questions, answered
- Do I have to declare foreign rental income in my home country?
- In most countries that tax residents on worldwide income, including the UK and the United States, yes. You normally declare the income at home and claim a credit for tax already paid in the country where the property sits, under a double tax treaty or domestic relief rules.
- Can I be taxed twice on the sale of a property abroad?
- You may have to report the gain in both countries, but double tax treaties usually give the country where the property is located the first right to tax it, and your home country then credits that tax. If your home country's tax on the gain is higher, you pay the difference there.
- What is withholding tax on a property sale?
- Some countries require the buyer to hold back part of the price when the seller is non-resident and pay it to the tax authority as an advance on the seller's tax. Spain and the United States both use this system. The seller later files a return and recovers any amount withheld above the final tax due.
