Non-Resident Income Tax in Spain (IRNR)

The Impuesto sobre la Renta de No Residentes (IRNR) applies to individuals and entities that are not Spanish tax residents but receive income or derive economic benefit from Spanish sources. The key taxable events include:

• Rental income from Spanish property — taxed at 19% for EU/EEA residents, 24% for others, on gross income (EU/EEA residents may deduct allowable expenses; others cannot)
• Deemed income on residential property not rented out — Spain imputes 1.1% (cadastral value revised since 1994) or 2% of cadastral value as income, taxed at IRNR rates
• Capital gains on sale of Spanish assets (real estate, company shares) — 19% flat rate
• Dividends and interest from Spanish sources — 19% withholding tax (subject to treaty relief)
• Professional services income earned in Spain — 24% (EU/EEA: 19%)
• Charter income from vessels in Spanish waters — 19% (EU/EEA) or 24%

IRNR is reported quarterly or annually via Modelo 210. Rental income is typically reported quarterly; deemed income and capital gains are reported annually. The filing deadlines and payment mechanics differ by income type.

Spain has an extensive network of double tax treaties (over 90 agreements in force) that can reduce or eliminate IRNR on certain income types. Treaty relief is not automatic — it must be claimed by filing a specific reduced-rate claim with the AEAT, typically supported by a certificate of residence issued by the tax authority of the treaty country.

Key Treaty Reductions

Under most of Spain's treaties, the withholding rate on dividends is reduced to 5–15% (from the domestic 19%). Interest is typically reduced to 0–10%. Royalties are reduced to 0–10%. Capital gains on real estate are generally not reduced by treaty — Spain retains the right to tax gains on Spanish real estate regardless of treaty provisions.

Permanent Establishment Risk

Non-residents who conduct significant business activities in Spain — whether through employees, agents, or a fixed place of business — risk creating a permanent establishment (PE) in Spain, which converts their IRNR exposure into full corporate tax or IRPF liability. We advise on PE risk assessment and mitigation, and on restructuring arrangements to reduce this exposure.

One of the most commonly overlooked IRNR charges is the imputación de rentas inmobiliarias — Spain's imputed income rule for non-residents who own Spanish residential property but do not rent it out commercially. Owning a Spanish holiday home, even if never let to a third party, creates an annual IRNR obligation that many non-residents are entirely unaware of until they receive an AEAT notification.

How the Imputed Income Is Calculated

The imputed income is a statutory percentage of the property's valor catastral (cadastral value — the value assigned by the local authority for land registry and taxation purposes). The percentage applied depends on when the cadastral value was last revised:

• 1.1% of the cadastral value — where the cadastral value has been revised by the relevant municipality since 1 January 1994 (the majority of urban properties)
• 2% of the cadastral value — where the cadastral value has not been revised since before 1994, or where the property has no cadastral value assigned (in which case 1.1% applies to 50% of the property's acquisition value or market value, as declared for wealth tax purposes)

The imputed income is then taxed at the applicable IRNR rate: 19% for EU and EEA residents, and 24% for residents of non-EU/EEA countries (including, since Brexit, UK residents). The resulting tax is typically modest in absolute terms but the obligation to file Modelo 210 is real, annual, and cumulates interest if ignored over multiple years.

A Practical Example

A German citizen (EU resident) owns a two-bedroom apartment in Torremolinos with a cadastral value of €80,000 (revised post-1994). The imputed income is €80,000 × 1.1% = €880. IRNR at 19% = €167.20 per year. The annual tax is small — but if the property has been held for 10 years without filing, the accumulated IRNR plus interest plus surcharges may reach €2,000–3,000, and if the AEAT issues a liquidation rather than accepting a voluntary late filing, formal penalties also apply.

What Triggers the Imputed Income Charge?

The imputación applies to any residential property that is available for use by the owner (or their family) and is not rented out commercially throughout the year. The key conditions for the charge are:

• The owner is a non-resident for Spanish tax purposes
• The property is classified as urban or rústica con construcciones (rural with buildings) for cadastral purposes
• The property is not rented out on a commercial basis for the full year — for periods of rental, rental income rather than imputed income is taxed, with the split calculated on a pro-rata basis for the non-rented portion of the year
• The property is not the taxpayer's habitual residence in Spain (though a non-resident generally cannot have a Spanish habitual residence without becoming a Spanish tax resident)

The imputación also applies to garages, storerooms and parking spaces separately assessed in the cadastre, if they are not rented commercially. It does not apply to land without buildings, or to commercial property.

Non-residents who spend significant time in Spain — or whose primary economic interests are in Spain — face the risk that the AEAT will challenge their claimed non-resident status. The 183-day rule is the most commonly invoked criterion, but it is neither the only test nor a safe harbour.

How the 183-Day Rule Works

Under Art. 9 of the Ley del IRPF, an individual is deemed a Spanish tax resident if they spend more than 183 days in Spain in a calendar year. The day count includes all days of physical presence in Spain — including transits through Spanish airports or ports of more than 24 hours — but excludes temporary absences from Spain that do not amount to a genuine change of tax residence (accidental or involuntary absences). The AEAT uses entry and exit data from the Ministerio del Interior's border control systems, airline manifests, mobile phone operator data, and bank card transaction location data to verify day counts.

Beyond the 183-day rule, Spanish tax residency can also arise where the taxpayer's principal economic interests are located in Spain — a test that is satisfied where the majority of the taxpayer's business activities, investments or employment income is Spanish-sourced, regardless of physical presence. This secondary test catches individuals who spend only 150 days in Spain but whose only meaningful income-generating activities are in Spain.

AEAT Inspection Powers and Evidence of Non-Residency

The AEAT has substantial powers to investigate claimed non-residency. In a formal inspection procedure, inspectors can request:

• Entry and exit stamps, boarding passes and travel records
• Credit and debit card transaction histories by location
• Mobile phone operator records showing the country of SIM card registration and connection
• Utility consumption records at the Spanish property
• Rental receipts or evidence of primary residence abroad (lease agreements, utility bills, electoral roll registration)
• Employment records showing work location
• Children's school enrolment records
• Medical records indicating habitual healthcare provider location

A foreign tax residency certificate — issued by the competent tax authority of the country where the taxpayer claims to reside — is an important piece of evidence, but it is not conclusive in Spanish law. The AEAT and Spanish courts have consistently held that a foreign residency certificate shifts the burden of proof but does not preclude a Spanish residency finding if the overall factual evidence points to Spain.

STS 1393/2024: The Supreme Court on Foreign Residency Certificates

The Tribunal Supremo's ruling 1393/2024 addressed directly the evidential weight of foreign tax residency certificates in AEAT proceedings. The Court confirmed that a validly issued certificate of tax residence from a treaty partner country creates a presumption of non-Spanish residency that the AEAT must rebut with specific factual evidence — the AEAT cannot simply disregard the certificate based on a general assertion that the taxpayer has ties to Spain. The ruling reinforces the importance of obtaining and maintaining an up-to-date foreign residency certificate when claimed non-residency is likely to be challenged, and it provides grounds for challenging AEAT assessments that have dismissed certificates without engaging with their content.

EU and EEA residents who derive a substantial proportion of their income from Spanish sources have the option to elect to be taxed as Spanish residents under IRPF rather than as non-residents under IRNR. This election — the opción por tributación como residente or declaración optativa — can significantly reduce the overall tax charge in some circumstances, but it requires careful analysis before being exercised.

When the Election Is Available

The election is available to individuals who:

• Are resident in another EU or EEA member state (including Norway, Iceland and Liechtenstein)
• Have obtained at least 75% of their total worldwide income from Spanish sources in the relevant tax year — meaning that the majority of their income is already within the Spanish tax net
• Cannot claim the personal allowances and deductions available to Spanish residents in their country of residence (i.e., the Spanish income represents such a dominant share that applying resident treatment in Spain is the only way they can access these reliefs)

The 75% threshold is calculated by reference to the taxpayer's total worldwide income — employment income, self-employment income, rental income, capital income and all other categories. A German resident who works exclusively in Spain under a cross-border arrangement and earns 90% of their income from Spanish employment is a typical candidate for the election.

What the Election Provides

Electing resident treatment under IRPF gives access to:

• The mínimo personal y familiar (personal and family minimum allowance): €5,550 for taxpayers under 65, €6,700 for those aged 65–74, €8,100 for those aged 75 and over, plus additional allowances for dependants and disability
• Deductions for contributions to Spanish pension plans, mortgage relief (for pre-2013 purchases), and other IRPF-specific deductions
• Progressive taxation at the general income scale rather than the flat IRNR rate of 19% or 24% — which is beneficial where income is modest enough that the progressive rates are lower than the flat rate after allowances
• The ability to offset Spanish-source losses against Spanish-source gains within the same tax year

When the Election Is Beneficial — and When It Is Not

The election is most beneficial for EU/EEA residents with moderate Spanish-source income who would otherwise be taxed at the 24% flat IRNR rate on gross income without deductions. For example, a Portuguese resident earning €30,000 from Spanish rental income would pay €7,200 IRNR at 24% (or €5,700 at 19% as an EU resident with expense deductions). Under the resident election, after the personal allowance of €5,550, the taxable income is €24,450 — generating a tax charge of approximately €5,400 at IRPF progressive rates. The saving is material and the election is clearly worthwhile.

Conversely, the election is generally not beneficial for high-income individuals whose income places them in the top IRPF bands (up to 47% plus regional surcharge), for taxpayers with complex deduction profiles in their home country that cannot be replicated under Spanish IRPF, or for taxpayers who would thereby lose access to treaty benefits in their home country.

Non-compliance with IRNR filing obligations — whether through failure to file Modelo 210 altogether or through late filing — triggers a tiered system of surcharges and penalties. The structure distinguishes between voluntary late filing and AEAT-initiated enforcement, with significantly different financial consequences between the two paths.

Recargos por Presentación Extemporánea (Voluntary Late Filing Surcharges)

When a taxpayer files Modelo 210 late but does so before receiving any AEAT notification or request, the general late-filing surcharges under Art. 27 LGT apply:

• 5% surcharge — filed within 3 months of the original deadline
• 10% surcharge — filed between 3 and 6 months after the deadline
• 15% surcharge — filed between 6 and 12 months after the deadline
• 20% surcharge + interest — filed more than 12 months after the deadline; interest is charged from the day after the deadline until the date of payment, at the delay interest rate (currently 4.0625% per annum)

These surcharges are calculated on the amount of tax that should have been paid on the original due date. For the typical imputación de rentas case (€100–300 in annual IRNR) they are small in absolute terms. For non-resident capital gains on property sales, where the IRNR liability can be €5,000–50,000 or more, even a 5% surcharge represents a material additional cost, and the 20% plus interest scenario can add thousands of euros.

Sanciones por Infracción Tributaria (AEAT-Initiated Penalties)

Once the AEAT identifies a filing failure and opens a procedure — whether through a requerimiento (formal request) or an inspection — the voluntary late-filing surcharge option is no longer available. Instead, formal penalty proceedings are initiated:

• Infracción leve (minor infraction): Non-declaration with no concealment — penalty of 50% of the unpaid tax
• Infracción grave (serious infraction): Non-declaration combined with use of false invoices or documents, or where the unpaid tax exceeds €3,000 and the omission rate exceeds 10% — penalty of 100% of the unpaid tax
• Infracción muy grave (very serious infraction): Fraud with deliberate concealment (e.g., false declarations of non-residency, fictitious transactions) — penalty of 150% of the unpaid tax

Reduction of formal penalties is available through the AEAT's conformidad system: a 30% reduction applies if the taxpayer agrees with the assessment (waiving the right to appeal), and a further 25% reduction applies if the penalty is paid within the voluntary payment period. In practice, a fully co-operative taxpayer facing a minor infraction can often reduce the effective penalty to 26.25% of the unpaid tax — still significantly more costly than voluntary late filing at 20%.
