Taxes on a Dubai flat: how holiday letting is taxed in Spain

Plenty of people buy in Dubai because of one line they have heard a thousand times: there is no tax there. It is half true, and the missing half is expensive. If you live in Spain, the flat can sit in Downtown or in Marina, the tax authority does not mind: your rental money is declared here, in your IRPF (Spain's personal income tax), at whatever rate the rest of your income puts you in.

Here is the short answer. A Spanish tax resident is taxed on their worldwide income, wherever it comes from. What your Dubai holiday home earns goes into the general tax base of the IRPF and adds to your salary or your pension, so it ends up taxed at your marginal rate, which in the top bands goes above 45%. Dubai charges you nothing on that income, so there is no tax from there to offset here. The practical result is that this let pays in Spain almost as if the flat were in Valencia.

Ignoring it does not make it go away. It is a sum worth doing properly before you buy, and repeating every year when you file. Let us go through it.

Why do you pay in Spain for a flat that sits in Dubai?

Because of tax residence. If you spend more than 183 days a year in Spain, or your centre of interests is here, you are a Spanish tax resident and you declare what you earn anywhere in the world. The Dubai flat does not escape that rule by being abroad.

What you do need to check is the double taxation treaty between Spain and the United Arab Emirates, signed in 2006 and published in Spain's official gazette (BOE) in January 2007. Its article 6 says that income from a property located in the Emirates "may be taxed in that other State"; in other words, the UAE could tax it. And article 22 sets out what Spain does so that you do not pay twice: it lets you deduct from your Spanish tax "an amount equal to the income tax paid in the United Arab Emirates".

Here is the catch that trips people up. Since the UAE charges no income tax on individuals, what you paid there on that let is zero, and zero is exactly what you can deduct in Spain. The treaty does not exempt you from paying: it prevents double taxation, which is not the same thing. If there was no tax there, you pay it in full here.

How is the let declared, and at what rate?

The money the stays leave you is income from immovable property (rendimiento del capital inmobiliario). You declare the income and subtract the expenses for those days: the proportional share of the insurance, the service charge, the utilities, the repairs, the holiday-home permit, the platform fees and the cost of management. What is left is what gets taxed.

And it is taxed in the general base, the same progressive scale your salary pays on, not the savings base. That is why the rate depends on your total income and on your autonomous region: each region sets its own regional portion of the IRPF, so the top band runs from 45% to a little over 50% depending on where you live.

There is one temptation worth killing straight away: the 50% reduction that applies to the letting of a main home does not count here. The Spanish tax authority says so plainly: that reduction "does not apply to the letting of tourist flats, since their purpose is not to meet a permanent housing need". A holiday home is short-stay by definition, so that discount is off the table.

The days the flat sits empty also count

No holiday let is occupied for all 365 days. And for the days the flat is available and unbooked, the tax authority does not sit still: it attributes a deemed income just for having it at your disposal. For a property abroad, which has no Spanish cadastral value, that deemed income is around 1.1% a year calculated on half the purchase price, spread across the empty days.

It is not a huge figure, but it turns up every year and plenty of people forget about it until a tax notice arrives. The more gaps your calendar has, the more deemed income you pay and the less real income you have taken, which is the worst possible combination. Keeping occupancy high does not only improve what you bill: it also trims the part you pay for the flat sitting idle.

Modelo 720: the form that has triggered the most fines

If the value of your real estate abroad exceeds €50,000, you have to file modelo 720, Spain's informational return on assets and rights held abroad. A Dubai flat almost always clears that threshold comfortably. It pays no tax by itself: it only reports that the asset exists. The window runs from 1 January to 31 March of the following year.

This form had a reputation as a death trap because the fines for not filing it were disproportionate. The Court of Justice of the European Union struck them down in its ruling of 27 January 2022 (case C-788/19), and Spain adapted the regime with Law 5/2022. The penalties are now the ordinary ones in the general tax law, not those monstrosities, but the form is still compulsory. Forgetting it no longer ruins you, though it is not free either.

What about Dubai's taxes?

This is where the reputation holds up. The UAE charges no income tax on individuals, and the 9% corporate tax that came into force in June 2023 leaves out, according to the Federal Tax Authority's guide, the income a natural person earns from letting property in a personal capacity. If you are an ordinary owner and you do not set up a licensed business to do it, you pay no tax in Dubai on the let itself.

What Dubai does have is paperwork. To let as a holiday home you have to register the property with the Department of Economy and Tourism (the former DTCM) and obtain the permit, which is renewable and carries a fee. And for every night the guest is charged the Tourism Dirham, a tourist fee collected stay by stay. These are not taxes on your profit, but they are business costs, and therefore expenses you deduct in your Spanish return. If you want the detail of how the day to day of a flat there works, we cover it in the guide on how holiday letting works in Dubai.

How this fits with managing the flat from Spain

The tax bill is calculated on what the flat actually earns, and that depends on it being well run even though you are six thousand kilometres away. In the flats we manage, guests' average ratings sit around 8 out of 10, and the typical stay lands at about five nights. That short-stay profile is exactly what puts you in the general base with no reduction, so the tax sum and the operations go hand in hand: every empty night is less income and more deemed income.

We handle the full operation remotely, from registration and guest reports to pricing and the guests themselves, and we give you clear accounts so that you or your adviser can complete the return without chasing invoices. You can see how we work in the Emirates on our Dubai page and in the guide on managing it remotely from Spain. And if what you want is to know what your flat would really leave you once costs and taxes are paid, write to us and we will work it out with you on your own case, not on a brochure example.

One last thing, and it is the important one: this is a general explanation, not your adviser's advice. International taxation has nuances that depend on your situation, so the fine detail is closed with a professional. What does not change is the starting point: a flat in Dubai owned by a Spanish resident is taxed in Spain, and it is worth knowing that before you sign, not in April.
