Spain Income Tax Guide for UK Expats (2025)

Spanish Tax Residency: The 183-Day Rule

The most important concept for UK nationals moving to Spain is tax residency. Spain considers you a tax resident — and therefore subject to Spanish income tax on your worldwide income — if any of the following apply:

• You spend more than 183 days in Spain in any calendar year (days in and out count; occasional absences don't break the count)
• Spain is the main base of your economic activities or interests (e.g., your business is based there, your income is generated there)
• Your spouse or dependent children habitually reside in Spain (creates a presumption of residency, which you can rebut)

The calendar year in Spain runs from 1 January to 31 December. If you arrive in Spain in, say, April and are still there at year end, you may become a tax resident for that year if you pass 183 days by 31 December. This can catch new arrivals by surprise — planning your arrival date with tax residency implications in mind is important.

Once you are a Spanish tax resident, you are liable for Spanish income tax (IRPF — Impuesto sobre la Renta de las Personas Físicas) on your worldwide income. UK income — salary, pension, rental income, dividends, capital gains — must all be declared on your Spanish tax return.

Spain Income Tax Rates (IRPF) 2025

Spain's income tax is progressive, split between a national rate and a regional rate that varies by Autonomous Community. The combined rates shown below are the national general rates. Most regions align closely with these, though Madrid, the Basque Country, and Navarre have notable differences.

These are marginal rates — each band applies only to income within that bracket. The personal allowance (mínimo personal) in Spain is €5,550 for most taxpayers (higher for those over 65 or 75), reducing the amount subject to tax.

The Beckham Law: 24% Flat Rate for Qualifying Expats

Named informally after David Beckham, who benefited from an earlier version when he signed for Real Madrid, the Régimen Especial para Trabajadores Desplazados (Special Regime for Displaced Workers — RETD) is one of the most powerful tax tools available to qualifying UK nationals moving to Spain.

What It Offers

• A flat 24% income tax rate on Spanish-source income up to €600,000 (47% above €600,000)
• Non-resident tax treatment (you are taxed as a non-resident even while living in Spain)
• Exemption from paying Spanish tax on most overseas income (dividends, capital gains, rental income from non-Spanish sources)
• Exemption from Modelo 720 overseas asset declaration during the regime period
• Benefit applies for the year of arrival plus the following 5 tax years (6 years total)

Who Qualifies?

Since 2023, the Beckham Law was extended to include holders of the Spain Digital Nomad Visa (DNV) — a significant expansion that has made it attractive to a much wider range of UK professionals. If you are a remote worker earning a good income from UK clients, the combination of the DNV and Beckham Law is extremely compelling.

Full details on eligibility, the application process, and how to combine the DNV with the Beckham Law are covered in our dedicated Beckham Law guide.

The UK-Spain Double Taxation Treaty

The UK-Spain Convention for the Avoidance of Double Taxation (signed 1975, subsequently updated) remains in force post-Brexit. Brexit did not affect this bilateral tax treaty, which operates independently of EU membership. This is an important point — UK nationals in Spain retain the full protections of this treaty.

The treaty allocates taxing rights between the UK and Spain for different types of income:

The treaty prevents full double taxation, but it does not always prevent you from having obligations in both countries. For example, UK rental income must be declared in both the UK (self-assessment) and Spain (Declaración de la Renta), with a credit in Spain for UK tax paid. This requires coordinated filing in both countries — a job for a specialist adviser familiar with both tax systems.

See our full guide to the UK-Spain Double Tax Treaty for comprehensive income-by-income analysis.

Declaring UK Income in Spain

As a Spanish tax resident, your annual Spanish income tax return (Declaración de la Renta) must include all worldwide income received in the calendar year. The filing window is typically April 3 to June 30 for the previous tax year.

UK Rental Income

Income from renting UK property must be declared in Spain. You apply allowable deductions (mortgage interest, management fees, maintenance costs — using UK rules or a simplified Spanish approach), then declare the net profit. UK tax already paid on this income generates a tax credit in Spain, reducing or eliminating Spanish tax on the same income.

UK Pension Income

As noted in the treaty section above, UK State Pension is taxable only in Spain — you should notify HMRC (form Spain-Individual, double taxation claim) to receive your State Pension gross. UK Civil Service / government pensions remain taxable in the UK. Private and occupational pensions require careful analysis — the treaty treatment can be complex, and errors are common.

UK pension holders need particular care — the UK pension in Spain guide covers how state pension and private pensions are taxed under the Spain–UK treaty, S1 healthcare entitlement, and the implications of transferring pensions to a QROPS.

UK Investment Income

Dividends from UK shares, interest from UK savings accounts, and gains from UK-held ISAs or investment accounts must all be declared in Spain. Note: UK ISAs lose their tax-free status once you become a Spanish tax resident. The income and gains within an ISA must be declared annually on your Spanish return. This surprises many UK nationals.

Spanish Wealth Tax (Impuesto sobre el Patrimonio)

Spain's Wealth Tax applies to Spanish tax residents' net worldwide assets above exemption thresholds. The basic structure:

Key exemptions and allowances:

• Personal allowance: €700,000 per person
• Primary residence exemption: up to €300,000
• Business assets used in your main economic activity: generally exempt

Regional variations are critical: Madrid applies a 100% bonus to the Wealth Tax, effectively eliminating it for Madrid residents — making Madrid the only major Spanish region where wealth tax is zero. Catalonia and the Valencia region apply full rates. This difference alone can be a significant factor for high-net-worth UK nationals choosing between Barcelona and Madrid.

The 2023 Solidarity Wealth Tax (ISF), introduced as a temporary measure, applies a national backstop rate on assets above €3 million for residents in regions (like Madrid) that had eliminated the standard wealth tax. Assets €3M–€5M: 1.7%; €5M–€10M: 2.1%; above €10M: 3.5%.

For a full breakdown of rates, regional exemptions (Madrid and Andalucía offer 100% exemptions), and how the Solidarity Tax applies to high-net-worth UK expats, read our dedicated Spain wealth tax guide.

Modelo 720: Overseas Asset Declaration

The Modelo 720 is an informational declaration (not a tax payment form) that Spanish tax residents must file if they hold overseas assets above €50,000 in any of three categories:

• Category 1: Foreign bank and financial institution accounts
• Category 2: Securities, life insurance policies, annuities, and pension rights held abroad
• Category 3: Real estate and property rights located outside Spain

The €50,000 threshold applies separately to each category. If you have a UK property worth £200,000 and a UK ISA worth £60,000, both categories trigger the obligation independently.

Modelo 720 is filed annually by 31 March for the previous calendar year. You must file in the first year of exceeding the threshold, and in any subsequent year where the value of any category increases by more than €20,000 from the last filed figure.

Hiring a Spanish Tax Adviser: What to Expect

Given the complexity of the UK-Spain tax interface — two tax systems, a bilateral treaty, Modelo 720 obligations, and potentially the Beckham Law — almost all UK nationals living in Spain benefit from professional tax advice. Here's what to expect:

What a Spanish Tax Adviser (Asesor Fiscal) Does

• Prepares and files your annual Spanish Declaración de la Renta
• Prepares and files Modelo 720 (overseas asset declaration)
• Advises on treaty treatment of different income types
• Coordinates with your UK accountant or advises on UK filing obligations
• Assists with Beckham Law applications and ongoing compliance
• Advises on wealth tax planning (including the Madrid vs Catalonia decision)

Typical Costs

We work with a network of English-speaking Spanish tax advisers who specialise in UK-Spain cross-border taxation. Our clients receive a referral as part of our post-arrival support package — see our moving to Spain guide for details.
