Leaving Spain for Dubai: the treaty clause that leaves you unprotected

Spain looks like the easiest of the big Mediterranean exits. The Emirates are not on its blacklist, the exit tax has thresholds high enough that most people never reach them, and where it does apply there is a deferral available on request.

All of that is true, and all of it is beside the point. The real difficulty in leaving Spain for Dubai is a single definition buried in article 4 of the tax treaty.

The exit tax, and why most people are under it

The Spanish exit tax, the impuesto de salida, sits in article 95 bis of Ley 35/2006. It has a duration test and a size test, and both have to be satisfied.

Duration: resident in Spain for at least ten of the fifteen tax periods before the last period you have to declare. If you were previously on the Beckham regime, the ten year clock only starts with your first year outside it.

Size, either of two limits: the market value of your shareholdings added together exceeds 4,000,000 euros, or, failing that, you hold more than 25 percent of a company and the shares you hold in it are worth more than 1,000,000 euros, in which case only those shares are caught.

The gain falls into the savings income base and is taxed on the savings scale:

Savings tax base	Rate
0 to 6,000 euros	19 %
6,000 to 50,000 euros	21 %
50,000 to 200,000 euros	23 %
200,000 to 300,000 euros	27 %

The gain is attributed to the last period you have to declare, through a supplementary self-assessment filed without penalty, late interest or surcharge, due in the filing window of the first year in which you are no longer a taxpayer. Most people moving to Dubai never reach either size limit.

The deferral works, unlike in France

This is where Spain is genuinely more workable than its neighbour. Article 95 bis paragraph 4 grants a deferral on application where the destination country has a treaty with Spain containing an information exchange clause. The Spain to UAE treaty has one, in article 25, so the deferral is available for a move to Dubai. The conditions:

• Security and interest under the general tax law. The security may be constituted wholly or partly on the affected shares themselves.
• Payment falls due by 30 June of the year following the end of the five year period, or two months after the shares are transferred if that happens sooner.
• Extension to ten years only for work-related relocations, for a maximum of five further years. Administrative silence on the application counts as refusal.
• Returning cancels it. Come back within five years without having sold the shares and the deferred liability, interest included, is extinguished.

Two footnotes. The special ten year regime in article 95 bis paragraph 6 is restricted to the EU and EEA, as is its notification form Modelo 113, and the frequently cited “Modelo 713” does not exist in the AEAT catalogue at all. If a document you have been given cites a 713, question the rest of it.

And one item routinely missed: on losing residency, all income not yet attributed must be brought into the last declarable period, by supplementary return without penalty or interest, within three months of ceasing to be a taxpayer.

The good news that people over-read

The Emirates are not on the Spanish list of non-cooperative jurisdictions. The consolidated order, last updated with effect from 28 June 2026, names Anguilla, Bahrain, Bermuda, Guernsey, Jersey, the Isle of Man, the Cayman Islands and a dozen others. The UAE appear nowhere.

That matters, because article 8 paragraph 2 of Ley 35/2006 keeps Spanish nationals who move to a listed jurisdiction taxable for the year of the change and the four following tax periods. Moving to Dubai does not trigger it. There is no four year tail.

So far, so comfortable. Here is the part that undoes it.

The clause that leaves you standing alone

Article 4 paragraph 1 letter b of the Spain to UAE treaty defines residents of the Emirates as individuals domiciled in the United Arab Emirates and who are nationals of the United Arab Emirates.

Read that twice. A Spanish, German or Italian national living in Dubai, holding an Emirates ID and a residence visa, is not a UAE resident for treaty purposes. The nationality requirement is right there in the text.

The consequence is structural rather than numerical. The tie-breaker cascade in article 4 paragraph 3, the permanent home and centre of vital interests sequence that normally resolves a dual residence dispute, is not available to you. Every distributive rule in the treaty, article 13 paragraph 5 on capital gains, article 17 on private pensions, article 21 on wealth, presupposes residence under article 4, so none of them shields you either. The residency question is decided by article 9 of Ley 35/2006 alone, on facts. A note of exchange in 2017 changed nothing here: it concerned recognition of the Mubadala group as a government institution for dividend purposes, not the residence definition.

Which means the facts have to be airtight

Article 9 has two alternative tests: more than 183 days in Spain in the calendar year, or your main centre of economic activities or interests in Spain. On top of that sits a rebuttable presumption: if your not-legally-separated spouse and dependent minor children habitually live in Spain, residency is presumed.

The day count has a sting. Spanish law counts days spent outside Spain towards the 183 unless you can produce proof of tax residency in another country. Whether the AEAT accepts a UAE residence certificate issued to a non-Emirati, given the treaty definition above, could not be verified from official sources, and we are not going to guess at it. What is clear is that days, economic centre and family location all have to be documented from the start.

The formalities are light. Modelo 030 notifies the change of address within three months, one month via Modelo 036 for business owners and professionals, and the change only takes effect against the administration once notified. For Spanish nationals, consular registration is compulsory and automatically removes you from the padron municipal, but the rule says explicitly that it does not prejudge whether you have met the tax residency periods. An indication, not proof.

What Spain keeps taxing

Rental income: 24 percent of the gross, with no deductions. The reduced 19 percent rate and the right to deduct actual costs are both reserved for residents of an EU or EEA state with effective information exchange. For a UAE resident it is 24 percent of the gross rent, with mortgage interest, IBI, community charges and depreciation all non-deductible. On a home kept for your own use, imputed income of 2 percent of the cadastral value, or 1.1 percent where that value has been revised in the current or previous ten periods. On sale, the buyer withholds 3 percent of the price and the gain is taxed at 19 percent.

Wealth tax on Spanish assets. Non-residents are liable under obligacion real, with a 700,000 euro allowance and a state scale from 0.2 to 3.5 percent. Since Ley 38/2022 unlisted shares count as Spanish situs where at least 50 percent of the assets are directly or indirectly Spanish real estate. The solidarity tax on large fortunes, Modelo 718, applies on the same basis, with a nil band to 3,000,000 euros and then 1.7, 2.1 and 3.5 percent. Billed as temporary, it now runs indefinitely. Anyone not resident in an EU state must appoint a representative resident in Spain before the filing deadline, and the 60 percent cap on the combined burden applies only under obligacion personal.

On inheritance the position improved. Since Ley 11/2021 the regional rules apply to all non-residents, not only EU and EEA residents, so an estate can be assessed under the law of the autonomous community where the largest share of the Spanish estate lies. There is no trailing period of its own.

What this means in practice

Spain’s written rules are the friendliest of the three. Its treaty is the least useful. The order that works:

1. Check the thresholds first. Ten of fifteen years, plus 4,000,000 euros or the 25 percent test. Below them, the exit tax is not your subject.
2. If you are above them, apply for the deferral before you go, and plan for security plus interest rather than treating it as a formality.
3. Do not count on the treaty. Assume article 4 leaves you outside it and build your position on article 9 facts instead.
4. Document days, economic centre and family location from day one. The presumption around spouse and minor children decides most of these cases.
5. Appoint the Spanish representative if the solidarity tax reaches you. It is a filing condition, not an option.

The Dubai side is the straightforward half. A company, a residence visa, an Emirates ID, a corporate tax registration, each with a published fee and a fixed deadline, and you can work the total out yourself in our company cost calculator. For a country with no exit tax at all that still holds on to you, read leaving the UK for Dubai.

We handle that half, the accounting, the tax registrations and the deadlines here. The Spanish half belongs with a Spanish adviser who works on non-resident cases regularly, and it belongs there before the move rather than after it.
