Myth: property abroad is tax-free if you live elsewhere

The myth

The claim goes like this: I live in country A, the flat is in country B, so country A does not see it and country B has no claim on me because I do not live there. Variants exist for rent ("the platform pays me abroad, nobody knows"), for sale ("I will sell and the money stays abroad") and for the whole idea ("it is a foreign asset, so it is outside the tax system"). The myth is attractive because the two tax systems really are separate and do not talk to each other in everyone's imagination. This article explains how the rules work in general terms. It is not tax advice and it contains no way to reduce tax; treaties and national rules differ, so check your own case.

What is actually true

In most countries two layers apply at the same time.

• The country where the property stands (the source country) usually taxes the rent and the gain on sale, because the income arises there. It may also charge annual property taxes, local charges and, in some countries, wealth or imputed-income taxes.
• The country where you are tax resident usually taxes your worldwide income, which includes foreign rent and foreign gains. Residence is decided by days spent and ties, not by where the money sits, see tax residency and the 183-day rule.
• A double taxation treaty between the two countries splits the rights and tells the residence country how to give relief: credit (foreign tax is deducted from home tax, normally up to the home tax on that income) or exemption with progression (the income is left out of the base but can affect the rate on other income). Which method applies depends on the specific treaty. See double taxation treaties and foreign property.

So the honest summary is that tax abroad is not zero. The combined burden may be close to the higher of the two rates, or higher in some cases, and it depends on the treaty, your documents and the rules in force in that year.

Where the myth comes from or is partly right

There are true kernels. Some countries tax a non-resident only on income from local sources, which is why a person with no income in a country may have nothing to file there. Some purchases carry no annual tax or a very low one. Treaties do prevent real double taxation in many cases, so the result is often smaller than people fear. And a particular country may have a holding-period rule under which a sale after several years is exempt, so a gain can be tax-free in a specific case. The mistake is to generalise from one such rule to "no tax".

Another source is the feeling of invisibility. Cross-border reporting has grown. Within the EU, digital platforms such as booking portals must collect and report to tax authorities the income of hosts who rent out property through them (Directive (EU) 2021/514, known as DAC7, in force from 1 January 2023, with reports due by 31 January of the following year), and tax authorities exchange that data. The Finnish tax administration describes the scheme on its DAC7 page. Banks also ask about the source of funds, see what the bank asks before a large transfer. Do not rely on a system not noticing; declare what the law requires.

Country examples

Poland (residence country). A Polish tax resident is taxed on worldwide income. Private rent outside a business is taxed by lump sum at 8.5%, and 12.5% on the part above PLN 100,000 a year, as reported for 2023 onwards. Whether foreign tax is credited or the income is exempted with progression depends on the treaty. A sale within five calendar years after the year of purchase is reported as taxed at 19% on the PIT-39 return. Details are in tax on foreign rental income for Polish residents and the official portal is podatki.gov.pl. We also found reports of a separate reporting duty to the National Bank of Poland for foreign assets above a high threshold; we could not confirm the details, so ask an adviser.

Germany (residence country). A person with a home or habitual abode in Germany is taxed on worldwide income. Foreign rent is declared in the return on the form for foreign income (Anlage AUS), and a private sale within ten years of purchase is, as reported, generally taxable with exceptions for own use. See foreign property tax return: German residents.

Czechia, Estonia, Latvia, Lithuania, Netherlands, Ireland (residence countries). Each taxes residents on worldwide income and has its own rates and holding periods, some of which changed recently and could not all be confirmed. Start with the matching guide: Czech residents, Estonian, Latvian, Lithuanian, Dutch and Irish. The overview rental income abroad: tax by country compares them.

Spain (source country). Non-residents without a permanent establishment file Spanish non-resident income tax on the Modelo 210 form, most commonly for rent, and the form also covers imputed income tax charged even when a property is not rented out, as reported by advisers. Advisers also report that residents of the EU/EEA may deduct expenses from rent while others may not; we could not confirm the current rates on the official page, so check on the Agencia Tributaria. A tax number is needed first, see NIE, NIF and other tax numbers.

Selling abroad. The source country often taxes a non-resident's gain, sometimes with withholding by the buyer or notary, and your residence country then looks at the same sale. The comparison taxes when selling property abroad as a non-resident covers the main countries.

How to act safely

• Before you buy, list both countries: the property country (purchase tax, annual tax, rent tax, sale tax) and your residence country (rent, gain, wealth or reporting rules). The guide annual property tax and bills for owners abroad helps.
• Find the treaty between the two countries on your own tax authority's official list. Check whether it is in force, the articles on income from immovable property and on capital gains, and the method article.
• Keep documents: lease, foreign tax return, proof of tax paid, purchase and sale contracts with costs and dates, and a tax residency certificate if the foreign office asks. They are what you need to claim relief.
• File on time in both countries where the law requires it. Foreign tax deadlines are separate from yours, and a missed foreign return can cost penalties.
• Check wealth, property and reporting rules in your own country, see wealth and property taxes on foreign real estate.
• If you move or spend more time abroad, your residence may change; see the 183-day rule. Treat advice from a seller or agent as marketing and ask a licensed tax adviser in both countries.
• Do not use structures promised to make tax disappear. Plan so that you can explain every transfer and every payment to a tax office and a bank. See also the myth about permits and passports.

FAQ

Do I pay tax in the country where the flat is if I live elsewhere? Usually yes on rent and often on a sale, under that country's own rules. Do I also pay at home? Usually you declare the foreign income at home, and the treaty or domestic law gives relief, often a credit. Do I pay twice? Not necessarily, but relief can be partial and depends on the foreign rate. Can I choose the lower rate? Generally not; the method follows the law and the treaty. Is an empty flat tax-free? Not always: some countries charge annual property tax or imputed-income tax regardless of rent. Do platforms report my rent? Within the EU, digital platforms report host income under DAC7, so assume it is visible.
