Wealthy families from the Gulf have made the Costa del Sol a second home, drawn by the climate, the privacy and the ease of the region. They arrive from jurisdictions with little or no personal income tax and no wealth tax, which makes Spain a particularly sharp contrast: the very things they never had to think about at home, worldwide income tax and an annual wealth tax, are exactly what a careless move to Spain can switch on. The prize is the home and the lifestyle. The risk is importing a tax system they left precisely to avoid.
The contrast that catches people
A family used to a zero-tax environment can underestimate what Spanish tax residence means, because it is so unlike home. Residence brings taxation on worldwide income and exposure to the wealth taxes, potentially reaching a global balance sheet that was never taxed anywhere before. For a large fortune, the annual cost of stumbling into Spanish residence unplanned is not a rounding error; it is a serious, recurring charge on wealth that had been entirely outside the tax net.
The status is annual and whole. Under article 12 of the Spanish personal income tax law the tax period is the calendar year and the tax accrues on 31 December, article 13 allowing a shorter period only on death. A family that crosses the line in October is resident for all twelve months, January dividend included.
Residence is settled under domestic law before any treaty is opened, and a tie-breaker engages only once two states both claim the same person.
Enjoy the home without becoming resident
The good news is that owning and enjoying a Costa del Sol home does not, by itself, make a family Spanish tax resident. Residence turns on presence, on where the centre of the family’s life sits, and on the family-based presumptions, all of which can be managed by a family that spends seasons in Spain while keeping its true base at home, provided the position is planned rather than assumed. The traps, especially the presumption that follows a spouse and children who live in the home year round, are the ones in our note on Spanish tax residence.
They come from a world without income tax or wealth tax. Spain has both. The whole art is keeping the home without importing the system they left home to avoid.
What article 9 actually decides
Article 9.1 sets out two circumstances, either sufficient alone. The first is presence for more than 183 days in the calendar year in Spanish territory, and it is no simple tally: sporadic absences are added back unless the taxpayer proves tax residence elsewhere, and where that country is treated as a tax haven the administration may demand proof of 183 days there.
The second has nothing to do with days. It applies where the main nucleus or base of the person’s activities or economic interests lies in Spain, directly or indirectly.
Then comes the presumption. Where the spouse who is not legally separated and the dependent minor children habitually reside in Spain under those same criteria, the taxpayer is presumed resident too. That is what catches Gulf families. It is rebuttable, on a residence certificate from the other state and a record that agrees.
Own it in a form that fits
Even without residence, a non-resident owner of a substantial Spanish property meets specific taxes and reporting, and can fall within the reach of the national tax on large fortunes on the Spanish assets, as we cover in our notes on non-resident owners in Spain and the solidarity tax on large fortunes. Choosing how to hold the property, in whose name or through what structure, is therefore part of the purchase, not an afterthought, as we set out in holding a Spanish home.
Held personally, the villa produces a bill even when empty. Article 13.1.h of the non-resident income tax law imputes an income to individuals owning urban property not used in a business, taxed under article 25.1.a at 24 per cent, the 19 per cent rate being reserved to residents of another Member State of the Union, or of an Economic Area State with effective exchange of information. Let the house, and article 24.1 taxes the gross rent, the expense deduction in article 24.6 reaching only Member State residents and, by its closing paragraph, residents of an Economic Area State with effective exchange of information.
Selling the company instead of the house escapes none of it. Article 13.1.i.3 treats as Spanish-source the gains on participations in an entity, resident or not, whose assets are principally, directly or indirectly, Spanish immovable property, the subject of our note on selling the property company instead of the property.
The special charge on entities that own Spanish property
Articles 40 to 45 of that law decide whether the corporate route works. Article 40 catches entities resident in a territory treated as a tax haven holding, under any title, Spanish immovable property or rights in rem of use or enjoyment over it. Article 41 takes the cadastral value as the base and article 43 sets 3 per cent, charged yearly on value, not income.
Everything turns on which jurisdictions fill the term. The tenth additional provision of Ley 36/2006, added by article 16.2 of Ley 11/2021, directs every statutory reference to a tax haven to the definition of non-cooperative jurisdiction in that law’s first additional provision, and the list approved under it is Orden HFP/115/2023 as amended by Orden HAC/649/2026 from 28 June 2026. It names Bahrain. It does not name the United Arab Emirates, so residence of the holding entity decides.
The exemptions in article 42 are closed: foreign states and public institutions, international organisations, entities carrying on in Spain continuously or habitually economic operations distinguishable from the mere holding or letting of the property, and listed companies. A company whose only activity is owning a family villa meets none. Article 45 accrues it on 31 December for payment in January and enforces it against the property.
What the wealth taxes reach when nobody is resident
A non-resident is within the wealth tax on a real obligation basis, on assets situated or exercisable in Spain. The third final provision of Ley 38/2022 rewrote that rule so that unlisted shares in any entity, wherever resident, whose assets are at least 50 per cent directly or indirectly Spanish immovable property, are deemed situated in Spain, that 50 per cent being computed on market values at the accrual date in place of net book values.
The temporary solidarity tax on large fortunes sits on top. Its chargeable event is net wealth above 3,000,000 euros at 31 December and its taxpayers are those of the wealth tax on the same terms, but the charge begins well above the threshold. Paragraph Nueve reduces the base by an exempt minimum of 700,000 euros, extended to every taxpayer by article 17 of Real Decreto-ley 8/2023, and the first band of the scale in paragraph Once taxes the first 3,000,000 euros of the resulting base at zero, so the rates of 1.7, 2.1 and 3.5 per cent reach only what lies above roughly 3,700,000 euros. The fifth additional provision of that decree-law then extended the tax itself until wealth taxation is reviewed alongside regional financing, so it is no longer the two-year measure announced.
Two features decide how it lands. Paragraph Dos.2 of article 3 bars cession to the autonomous communities, so no regional decision reaches it, and paragraph Quince allows deduction only of the wealth tax quota effectively paid, so a region that rebates that tax to nothing leaves nothing to deduct. It is a floor under the combined charge rather than a ceiling, the point of our note on the Spanish regions where the wealthy pay no wealth tax.
What changed on the Gulf side
The assumption of a home jurisdiction with no corporate tax at all has expired. The United Arab Emirates issued its corporate tax law on 9 December 2022, and the Ministry of Finance states that the Federal Decree-Law applies to financial years beginning on or after 1 June 2023, so a holding entity there now files at home and the shorthand that the structure carries no tax anywhere has stopped describing it.
Bahrain moved next. Under Decree-Law No. 11 of 2024 the National Bureau for Revenue applies a domestic minimum top-up tax from 1 January 2025 to multinational groups with annual global revenue of at least 750 million euros, at a minimum 15 per cent on profits earned in the Kingdom. It will not touch a family holding company, and it is separate from the Spanish list that decides the 3 per cent charge. Our note on Bahrain as a Gulf base looks at the jurisdiction from the European side.
The information side closed first. Under the common reporting standard, implemented in the Union by Directive 2014/107/EU, a financial institution includes a custodial institution, an entity holding financial assets for the account of others as a substantial part of its business. The duty sits with the custodian, not the client. Where the account holder is a passive non-financial entity, the institution must identify the controlling persons, and section I.A.1 of Annex I then requires both to be reported, the entity by name, address and residence and each reportable controlling person alongside it. The entity is added to the file; the individual is not removed from it, which is the position our note on the reporting duties for a European portfolio held by a non-resident sets out.
Privacy, succession and the long view
Gulf families also tend to care about discretion and about how assets pass within the family, both of which interact with Spanish rules in ways worth settling early, including the succession position in our note on who inherits your Spanish villa. Handled as one plan, the Costa del Sol home is exactly what the family wanted, a private, sunlit base, with the home-country advantages preserved. Handled casually, it can quietly pull a global fortune into a tax system the family had spent a lifetime outside.
The governing instrument is Regulation (EU) No 650/2012, applying to persons dying on or after 17 August 2015. Article 21 refers the succession as a whole to the law of the deceased’s habitual residence at death, article 22 allows a choice of the law of a State whose nationality he holds at the choice or at death, and article 20 makes that choice work outside Europe, whatever State the chosen law belongs to.
The limits are easy to overstate in both directions. The professio iuris reaches the succession and not the tax, article 1.1 excluding revenue, customs and administrative matters; it is confined to a law of nationality; and article 35 lets a court refuse a provision of the chosen law only where application would be manifestly incompatible with the public policy of the forum.
Jurisdiction runs separately. Article 4 gives the whole succession to the courts of the Member State of habitual residence, so it does not engage for someone habitually resident in the Gulf, and article 10.1 gives a Member State where assets are located jurisdiction over the whole estate only where the deceased held its nationality or had a previous habitual residence there and, when the court is seised, no more than five years have passed since that residence changed. Failing both, article 10.2 leaves the Spanish courts with the Spanish assets alone, the fragmentation our note on cross-border succession in Europe addresses.
If no choice is made and Spanish common law governs, the reserved share bites. Article 808 of the Civil Code reserves two thirds of the estate to children and descendants. Article 813 adds that the testator may impose on it no charge, condition or substitution of any kind, save what is provided as to the widow’s usufruct and in articles 782 and 808. The prohibition is not absolute, and its exceptions sit inside the same sentence.
