Most buyers focus on one number when they purchase property abroad: The price. The tax exposures attached to the title never appear on the closing statement, and several of them apply whether or not you ever move in, rent the place, or spend a single night there.
In many countries, owning residential property is a taxable status in its own right, separate from any income the property earns and separate from where you live. A home abroad can create an annual tax bill, pull you into a second country’s tax system, follow you into a capital gains charge when you sell, and reach past your death into your estate.
The exposures fall into six areas, each tied to ownership rather than to rent or residence.
The Tax That Applies Even When Your Home Sits Empty
Spain charges non-resident owners tax on a home even when it earns nothing at all. The mechanism is renta imputada, an imputed rental income the tax authority assumes your property generates simply because you own it.
The charge takes 1.1% of the property’s cadastral value if that value has been revised in the last ten years, or 2% if it has not. You then pay 19% on that amount as a resident of the European Union (EU) or European Economic Area (EEA), and 24% as a resident of anywhere else.
On a home with a €100,000 cadastral value revised in that window, the annual charge for a non-EU owner works out to roughly €264. That is a modest sum, but the obligation behind it is easy to miss.
Filing falls to you, on Modelo 210, the non-resident income tax return, and the tax agency sends neither a bill nor a reminder. Miss the deadline, and surcharges accrue for every month the filing is late.
(A separate European Commission challenge, at the reasoned-opinion stage since April 2026, targets a narrower point, that a non-resident who lives in a Spanish property cannot exempt it the way a resident exempts a main home. The charge on a genuinely empty second home, which residents pay too, is not what the Commission is contesting.)
Ownership can also become more expensive when your own status changes rather than the property’s. Brexit reclassified British owners in Spain as non-EU residents overnight, moving them from 19% on net rental income to 24% on gross rent with no deductions allowed.
A German landlord with €15,000 of gross rent and €5,000 of costs pays 19% on €10,000, or €1,900. In the identical position, a British landlord pays 24% on the full €15,000, which comes to €3,600, close to double the tax on the same flat.
None of this touches the separate municipal property tax, the Impuesto sobre Bienes Inmuebles (IBI), which the town charges every owner regardless of residence or use.
Spain is not unusual in taxing the fact of ownership rather than the income from it. Portugal layers its own Adicional ao Imposto Municipal sobre Imóveis (AIMI) on top of ordinary property tax, charging individual owners 0.7% a year on the portion of their residential holdings’ taxable value above €600,000.
The lesson holds wherever you buy: Confirm what a country charges an owner who earns nothing and lives elsewhere, because that number, not the rental yield, is the one that recurs.
The Home That Can Make You a Tax Resident
Ownership can settle a bigger question too, which country holds the right to tax your worldwide income.
When two countries both claim you as a tax resident under their domestic rules, the tie is usually broken by the treaty between them, and most treaties follow the same sequence, set out in the model convention published by the Organisation for Economic Co-operation and Development (OECD).
The first test is where you have a permanent home available to you. A dwelling that is continuously available for your use, owned or rented, can settle your tax residence on its own.
Keep a permanent home in only one of the two countries, and that country wins. Buy an apartment abroad and hold it available year-round, and you have handed a second country a strong argument that it is your home.
A vacation home does not automatically override a main home somewhere else.
If you keep a permanent home in both countries, the treaty moves to the next test, your center of vital interests, meaning where your family, work, and finances sit. A Munich family with a year-round apartment in Marbella keeps a permanent home in both places, so that first test settles nothing.
The family’s work, schooling, and finances all sit in Munich, and that is what decides it, in Germany’s favor.
Some countries skip the treaty and treat available accommodation as a residence trigger in their own law. The United Kingdom’s Statutory Residence Test can make you automatically UK resident if your only home is in the country and you spend enough time in it, and Spain looks past day-counting to whether your main center of economic interests sits there.
The real exposure shows up in the sequence of a move. Buy first, relocate second, and cross a residency threshold before you have planned the order, and a country can tax your entire worldwide income rather than just the local rent.
IMI’s analysis of why the 183-day rule works differently in every country shows how far jurisdictions like Spain, France, and Italy reach beyond a simple day count.
The Wealth Tax That Reaches the Property Itself
Income taxes apply to what a property earns. A wealth tax applies to what it is worth, and a handful of countries levy one on real estate whether or not the property produces a cent.
Only four OECD members run a broad annual tax on net wealth: Norway, Spain, Switzerland, and Colombia. Several others, including France, tax specific categories of assets, and real estate is the category most likely to be caught.
France taxes real estate wealth through the Impôt sur la Fortune Immobilière (IFI), which applies once the net value of your property exceeds €1.3 million on January 1. A French resident owes it on real estate worldwide, while a non-resident owes it on French property alone.
Rates run from 0.5% to 1.5%, with mortgage debt deductible from the base. Own a €1.5 million home on the Côte d’Azur and live in London, and France still sends an annual wealth tax bill.
Spain runs two overlapping wealth taxes. The regional tax, Impuesto sobre el Patrimonio, applies to net assets above €700,000, with non-residents charged only on assets located in Spain.
On top of it sits the national Solidarity Tax on Large Fortunes, introduced in 2022 and now permanent, which reaches net wealth above €3 million and overrides regional relief.
Madrid and Andalusia waive the regional wealth tax in full, and buyers often assume that leaves them with no wealth tax at all in Spain. A non-resident now claims the same €700,000 allowance as a resident, extended at the end of 2023 and backdated to 2022, so the solidarity tax only bites above roughly €3.7 million.
Hold prime Spanish property worth €5 million, and the solidarity tax applies even in a full-relief region, on a scale that starts at 1.7% and climbs to 3.5% on the largest fortunes.
Late in 2025, the Supreme Court extended the wealth-tax fiscal shield to non-residents, and Spain’s central tax tribunal carried the same logic into the solidarity tax that December. The shield caps combined income and wealth tax at 60% of taxable income, so a non-resident with little Spanish income can see the charge cut, subject to a floor that preserves part of it.
Switzerland taxes wealth at the cantonal level, with thresholds low enough to reach well beyond the very rich. In Zurich the tax starts at around CHF 80,000 of net wealth, and a property you own contributes to that base every year you hold it.
The Bill That Arrives When You Sell
Selling a home abroad can trigger tax in two places at once. Under most treaties, the country where the property sits has the first right to tax the gain, and your country of residence can tax it again, with credits or exemptions meant to soften the overlap.
The exemption you rely on at home may not travel cleanly. A US owner can apply the principal residence exclusion, up to $250,000 of gain for a single filer and $500,000 for a couple, to a foreign home that meets the ownership and use tests.
The country where the property sits can still tax the same gain under its own rules.
Local rules can be punishing on their own. France taxes a non-resident’s gain at 19% plus social charges, and the social-charge rate turns on where the seller is covered for social security.
A seller affiliated to a system in the EU, EEA, Switzerland, or the United Kingdom pays only the 7.5% solidarity levy, while a seller covered elsewhere pays the full 17.2%. Long ownership erodes both, with full relief from the income-tax portion after 22 years and from social charges after 30.
Mexico taxes a non-resident seller through the notary at closing, either 25% of the gross sale price or 35% of the net gain, and the choice made there is usually final. Some residence regimes then relieve the gain for their own residents, and Cyprus exempts foreign property from capital gains tax outright while Andorra exempts it after a ten-year hold, so the outcome depends heavily on both countries involved.
Currency movement creates a tax that catches US owners by surprise. Paying off a foreign-currency mortgage can produce a taxable gain measured in dollars even when the property itself barely moved in value, taxed as ordinary income, while the matching loss is not deductible.
You can owe US tax purely on the exchange rate. In Spain the buyer holds back 3% of the price at closing and pays it to the tax office against the seller’s gain, and the seller then files on Modelo 210 within roughly four months to settle the balance.
The Inheritance Rules Your Heirs Did Not Choose
A home abroad outlives you, and the country where it sits can tax it when you die regardless of where you lived. France charges inheritance tax on French property even when the person who died and the person who inherits are both non-residents, and Spain and Italy apply the same location-based principle.
Civil-law countries add a second problem, deciding who inherits rather than leaving it to you. Forced heirship rules in France, Italy, and Spain reserve fixed shares of an estate for children and a spouse, and those shares override the instructions in your will.
In practice, children can claim their reserved shares against a will that leaves everything to a surviving partner, and the partner’s inheritance shrinks to make room. There is a route around the succession question.
The European Union Succession Regulation, in force since August 17, 2015 and known as Brussels IV, lets you elect the law of your nationality to govern your estate instead of the law of your habitual residence, which can switch off forced heirship. It applies across the EU except Denmark and Ireland, and it still reaches British nationals who own property in participating states.
Two limits keep it from being a clean fix. The regulation governs succession, not tax, so France still levies French inheritance tax on the French house whatever law you choose.
Even a valid election has its limits. France amended its civil code in 2021 to let children who are EU nationals or residents claim a compensating share, and Germany’s Federal Court refused an English-law election that disinherited a son in 2022 on public-policy grounds.
One practical trap sits in the paperwork. A second will drawn up for the foreign property can cancel the main one by accident if it carries a blanket clause revoking all previous wills.
Coordinate the two documents, or use a single will that covers both estates.
The Paperwork That Carries the Penalties
Two kinds of filing sit behind a home abroad, and both carry penalties for getting them wrong. One is the paperwork the property’s country expects, and the other is the disclosure your home country expects.
On the property side, the risk is the silent filing. Spain’s Modelo 210 is self-assessed and the tax agency issues no reminder, so the costliest mistake non-resident owners make is simply never filing the imputed income on an empty home, with surcharges mounting for every month it goes unfiled.
The second failure sits at home, in the disclosure regime and its fines. A Spanish tax resident who owns a property abroad worth more than €50,000 has to report it on Modelo 720, the foreign-asset declaration.
The old regime stacked several penalties, a fine of 150% of the tax calculated on the undeclared assets, flat fines for each missing item, and treatment of the assets themselves as unexplained income with no time limit.
Together they could exceed the entire value of what a person held abroad, which is how one retiree reached a €442,000 bill on €340,000 of foreign savings. The Court of Justice of the European Union struck the regime down in January 2022.
Spain rebuilt the regime that year, with fixed penalties starting at €20 per item and a four-year limit, but the duty to file remains.
Disclosure is not always where a home country stops. Italy taxes the foreign home directly, charging its residents 1.06% a year on the value of real estate they own abroad through the Imposta sul Valore degli Immobili all’Estero (IVIE).
United States owners face a different disclosure map.
The main foreign-asset forms do not capture a home held in your own name, but they do capture the accounts, mortgages, and any company or partnership used to hold it, the Foreign Bank Account Report (FBAR) and Forms 8938, 5471, and 8865, each with its own penalty for a missed filing.
Assuming no one will connect the dots is not a plan. Under the Common Reporting Standard (CRS), tax authorities in more than 100 countries automatically exchange financial-account information every year, which means the country you left and the country you bought in can compare notes without asking you first.
Owning Is the Event, Not Just Buying
The tax cost of a home abroad runs well past the figure you pay at closing. It is a stream of obligations that lasts as long as you own the property and does not stop when you die.
Plenty of jurisdictions charge a foreign owner very little, and the United Arab Emirates and the territorial-tax countries that do not tax foreign income sit at the light-touch end. The problems concentrate in high-tax civil-law Europe, exactly where a great many second homes change hands.
The way to keep a purchase from turning into a problem is to map it before you buy, not after. That means pricing in what the property’s country charges an owner who earns nothing and lives elsewhere, whether the purchase or a later move hands that country a claim on your worldwide income, and what your home country expects you to declare once you own it.
Where a country taxes ownership itself, a home is not a passive asset sitting quietly on a balance sheet. It is a recurring liability, and the time to understand it is before the money leaves your account.
