Tax guide for British property owners in Spain

This article was developed with legal input from Salama Legal SLP, specialists in Spanish property tax and international taxation.

Owning property in Spain as a non-resident comes with a specific set of obligations, and understanding tax in Spain for non-residents early is one of the most important steps you can take. Spain applies its own regime for non-residents (the IRNR, or Non-Resident Income Tax), which operates alongside the double tax treaties it has signed with more than 90 countries, and an increasingly effective system of automatic exchange of fiscal information (CRS, DAC2, and Spanish Form 238).

The range of Spanish property taxes that apply to non-resident owners, from imputed income to rental returns and capital gains, can be broader than most people expect. This article covers the most common areas where non-resident owners tend to encounter difficulties, and how to stay on top of them.

1. Imputed income: the tax on properties you’re not renting out

Even if your property in Spain is empty and generating no income, Spain still applies a deemed income charge to the owner simply for having it available for personal use. This is one of the lesser-known aspects of non-resident property tax in Spain: imputed income on real estate, regulated under Article 13.1.h) of the Non-Resident Income Tax Act (TRLIRNR).

How it is calculated:

• 1.1% of the cadastral value if it has been revised within the last ten years
• 2% of the cadastral value if the revision is older
• Standard IRNR rates then apply: 19% for EU/EEA residents and 24% for residents outside the EU (which includes post-Brexit UK)

A few common misunderstandings worth clearing up:

• “My flat is empty, I have nothing to declare” – this is not the case under Spanish law
• “I already pay IBI in Spain, so that covers it” – IBI is a municipal tax; the IRNR is a separate national obligation
• “My accountant at home handles it” – this is often not the case unless you have dual specialisation

Imputed income is declared annually via Form 210, between 1 January and 31 December of the year following the accrual period. For most average properties the annual amount is modest (typically between €100 and €600), but years of unfiled returns accumulate interest and surcharges that are worth avoiding.

The Spanish Tax Agency (AEAT) now automatically cross-checks data from the Cadastre, the Property Registry, and the international CRS framework to identify non-filers, so this is an area that has become much easier for authorities to monitor.

2. Holiday and long-term rentals: the annual filing most owners don’t know about

If your property is rented out, whether as a holiday rental via Airbnb or Booking.com, or under a long-term lease, the obligations around rental income tax in Spain change significantly.

Filing calendar is as follows:

• Following the latest regulatory reform, rental income earned by non-residents is now declared annually via Modelo 210, between 1 and 20 January of the year following the accrual period (it is no longer quarterly)
• Each property is declared separately, consolidating all income and deductible expenses for the calendar year
• If the property has been sold during the year, the annual rental return sits alongside the separate capital gains return (see section 3)

What you can deduct depends on where you live:

EU/EEA residents are taxed at 19% on net income, meaning gross rent minus deductible expenses such as IBI, community fees, mortgage interest, utilities paid by the owner, depreciation at 3%, platform commissions, cleaning costs, and insurance.

Non-EU/EEA residents, including UK owners after Brexit, are taxed at 24% on gross income with very limited deductions available. This is a meaningful difference that can significantly affect the effective tax rate, particularly for British owners who have purchased in Spain to rent out. Double tax treaties come into play here, and in some cases it is worth considering how the rental activity is structured from the outset.

One more thing to know about platform rentals:

Via Form 238 (DAC7), platforms now report directly to the AEAT the number of nights rented, gross income, cadastral reference, and owner details. The AEAT cross-references this against filed returns, and where no return has been filed, it typically opens a review process. If the AEAT acts before a voluntary filing is made, the standard late-filing surcharges of 5-20% are replaced by penalties of 50-150% of the unpaid tax, so it is always preferable to file proactively.

3. Selling your property: the 3% withholding and the three-month deadline

When selling property in Spain as a non-resident, the process works in two steps.

First, the buyer is legally required to withhold 3% of the sale price and pay it directly to the Tax Agency via Form 211. This is a legal obligation of the buyer and is documented in the deed itself.

Second, the non-resident seller must file Form 210 declaring the actual capital gains tax in Spain within three months of the deed date, calculating the real gain or loss and, where appropriate, requesting a refund of any excess withheld.

The 3% is an advance payment, not the final tax. If the actual gain produces a lower tax liability than the amount withheld, the seller is entitled to a refund. If Form 210 is not filed within the deadline, the right to recover the excess withholding is lost.

A few things commonly missed:

• The 3% withheld by the buyer does not settle the tax position on the sale. Form 210 must be filed regardless, even if the result is zero or produces a refund
• Keep invoices for improvements, the original ITP transfer tax, notary fees, and registry costs, as these all increase the acquisition cost basis and reduce the taxable gain
• Spain does not apply inflation adjustments to the acquisition cost for non-residents, which is a relevant difference compared to some other jurisdictions
• If the property is sold at a loss, Form 210 still needs to be filed in order to recover the 3% withheld
• The three-month deadline is short and firm: once it passes, automatic surcharges apply

The applicable tax on selling property in Spain is 19% for EU/EEA residents and 24% for residents in third countries.

4. Declaring Spanish income in your country of residence: how double tax treaties work

This is the area where most confusion about taxes in Spain for foreigners arises, and where owners most commonly either overpay or miss obligations without realising.

Spain has signed double taxation treaties (DTTs) with more than 90 countries, all based on the OECD Model Convention. The double tax treaty between Spain and the UK is particularly relevant for British owners, and the general rule under all these agreements is that income from Spanish property (rental income and capital gains on sale) is taxable in Spain. It may also be taxable in the owner’s country of residence, which will normally apply a mechanism to avoid double taxation.

There are two typical mechanisms in DTTs:

• Exemption with progression: the country of residence exempts the Spanish income but takes it into account when calculating the rate applicable to the rest of the owner’s income (Germany applies this in certain scenarios)
• Credit method: the country of residence taxes worldwide income but allows the Spanish tax paid to be credited, up to the limit of the tax that would otherwise be due locally on that same income (this applies in the UK, USA, Netherlands, and France, among others)

Common mistakes when declaring in the home country:

• Not declaring Spanish income on the assumption that it was already taxed in Spain. In most cases it still needs to be declared, with the foreign tax credit applied
• Not keeping documentary evidence of the tax paid in Spain. Without a stamped Form 210 and proof of payment, the credit cannot be applied at home
• Applying the wrong exchange rates. The AEAT requires euros, but the country of residence usually requires local currency at the accrual date
• Miscalculating the credit limit. The country of residence will not allow a credit greater than the tax that would otherwise be due there on that same income
• Not checking whether the treaty contains a “subject-to-tax” clause that may limit the exemption

When an owner also has other international income streams such as investments, foreign pension plans, stock options, or ongoing inheritances, cross-border tax planning becomes particularly worth attending to.

5. Offshore structures for Spanish property: why they rarely work as expected

Understanding Spain tax for expats who hold property through offshore structures is an area where misconceptions are particularly common. Purchasing a Spanish property through an offshore company (Panama, BVI, Jersey, Guernsey, and similar) or through a foreign trust is an approach that has often been used with the expectation of privacy, tax efficiency, and succession planning benefits. In practice, especially since the CRS came into force and anti-avoidance rules were tightened, the results tend to be quite different.

A few things to be aware of:

• Special Tax on Real Estate of Non-Resident Entities (GEBI): a 3% annual levy on the cadastral value applies when a property is held by an entity resident in a jurisdiction classified as a tax haven or one without an adequate exchange-of-information treaty. This is a recurring cost that typically outweighs the supposed advantages
• Double tax treaties don’t apply to entities without real substance. The AEAT and Spanish courts reject purely instrumental structures
• Income attribution to the ultimate beneficial owner applies under international tax transparency regimes, particularly where there is effective control from Spain or another EU jurisdiction
• Inheritance tax treatment can be unfavourable. Spain does not recognise the trust as an autonomous legal entity, and the ISD (Inheritance and Gift Tax) applies based on the beneficiary rather than the settlor, which often complicates planning
• Exit taxation applies when the structure is unwound. Liquidating the entity or transferring shares can trigger significant capital gains taxation on latent appreciation

In practice, a “trust + offshore company + Spanish entity” structure often ends up being considerably more expensive than direct ownership or a properly designed EU-based vehicle.

Worth knowing before you buy:

Before buying property in Spain through any non-Spanish structure, a cross-jurisdictional tax analysis covering Spain, the country of residence, and the country of the entity is essential. Skipping this step often results in the same tax being paid more than once.

6. International successions: planning ahead makes a real difference

When it comes to property inheritance in Spain, there are several aspects that are rarely anticipated and worth understanding in advance.

• The applicable succession law is governed by EU Regulation 650/2012, which allows the deceased to choose their national law via a will. This is an option that few people exercise, and it can have significant consequences
• Spanish inheritance tax (ISD, Impuesto sobre Sucesiones y Donaciones) applies to the heir on the acquisition of Spanish assets, with effective rates ranging from 0% to 34% depending on the autonomous community where the property is located
• Non-resident heirs have been entitled since 2014 (following a CJEU ruling) to apply the most favourable autonomous community regime. Many are unaware of this and end up paying the state-level rate when a lower rate would apply
• The inheritance tax of the country of residence of either the deceased or the heirs may also apply, under its own rules (such as UK Inheritance Tax or French Droits de Succession)
• Mismatches between fiscal and registry ownership can arise when corporate structures or trusts are involved

International succession planning is best addressed in advance, ideally at the time the property is acquired, rather than later when the available options are more limited.

7. Administrative details that can trigger unnecessary complications

Finally, there are a couple of smaller administrative points that are straightforward to manage but can cause disproportionate complications if overlooked:

• Getting the NIE right in Spain is key for every co-owner. The AEAT needs to identify each tax-liable party. If one is missing, review processes tend to follow
• Appoint a fiscal representative in Spain when required. This is mandatory for residents in countries without a treaty or with limited exchange-of-information clauses
• Keep your address updated with the AEAT. If your address in your country of residence changes and this isn’t communicated to the AEAT, notifications continue going to the old address. Once deadlines lapse, decisions can become final without you having had the chance to respond
• Check for discrepancies between the Cadastre, Property Registry, and AEAT records. These are common after inheritances or following divorces where property has been reallocated
• Don’t assume the agency that handled your purchase is managing ongoing obligations. Most real estate agencies do not take on post-completion IRNR responsibilities

Staying on top of it

For non-resident owners, the annual non-resident income tax compliance cost is generally moderate. What tends to create larger issues is when obligations go unaddressed over a number of years, as interest and surcharges accumulate, and more complex situations such as a sale or inheritance become harder to manage.

The AEAT has more information on properties owned by non-residents than ever before, drawing on the Cadastre, Property Registry, Form 238 data from platforms, CRS/DAC2 exchanges, and beneficial ownership declarations. Staying up to date is the straightforward way to keep your position clean.

If you own property in Spain and have questions about any of the areas covered in this article, it is always worth getting advice that is specific to your situation, particularly if a sale or inheritance is on the horizon.
