As a property agent working with British buyers in southern Spain, I often get asked one key question: “Will I have to pay tax twice?” The good news? Spain does have a double taxation agreement with the UK, designed to prevent exactly that.
In this guide, I’ll explain what the treaty covers, how it affects different types of income, and what you need to know—especially if you’re buying a home or planning to live part-time in Spain.
Understanding the UK–Spain Double Tax Treaty
What is a double taxation agreement?
A double taxation agreement (DTA) is a legal arrangement between two countries to avoid taxing the same income twice. Spain and the UK have such a treaty in force, signed in 2013 and effective since 12 June 2014 for UK taxes and 1 January 2015 for Spanish taxes (Gov.uk).
When did the current treaty come into effect?
The current treaty came into force in 2014, replacing a previous 1976 version. Since then, it’s been used by thousands of expats and property owners to clarify where and how their income should be taxed.
Which types of income does it cover?
-
Pensions and state benefits
-
Rental income from UK or Spanish property
-
Interest and dividends
-
Capital gains
Each category has its own rules depending on your tax residency.
How the Treaty Affects British Residents in Spain
Pensions, savings, and property income
Let’s say you’re retired and receiving a UK pension while living in Spain. Under the treaty, you generally pay tax in Spain, your country of residence, not the UK. The same applies to interest earned from UK bank accounts or rental income from UK properties.
Do I have to file tax returns in both countries?
It depends on your residency status. Most of my British clients who live full-time in Spain file an annual Modelo 100 (Spanish tax return) and Modelo 210 if they have rental income. If you’re still considered UK tax resident, you may also need to file with HMRC.
Tax residency and common misconceptions
Being in Spain more than 183 days per year usually makes you a Spanish tax resident—but not always. Some clients assume residency is based on where they own a home, but that’s not the case. It’s about time spent, ties to each country, and other criteria. I always recommend getting professional tax advice early.
Real Estate and Double Taxation: What Buyers Should Know
Do I pay tax in Spain if I rent out my UK home?
Yes, you’ll likely need to declare that income in Spain as a resident, but the UK may still withhold some tax. In that case, the DTA allows you to offset the UK tax against your Spanish tax bill—so you’re not paying twice.
Buying a home in Spain: what to declare and where
Buying doesn’t make you a resident by default, but it can change your obligations. For example, non-residents who own Spanish property must file an annual tax return (Modelo 210), even if they don’t rent it out.
My experience helping British clients navigate tax issues
Many British buyers I’ve worked with had initial concerns about taxation. When I help them understand the agreement and refer them to trusted tax professionals, those worries usually disappear. One couple I helped in Manilva thought they’d be taxed on their UK pension twice—turns out, Spain had sole taxing rights under the treaty.
How to Claim Tax Relief or Avoid Double Taxation
The DT Spain – Individual form explained
This HMRC form allows Spanish residents to claim exemption or refund of UK tax that should not apply under the treaty. You’ll need to prove Spanish residency with supporting documents (HMRC DT Notes)
What documents you need and where to submit them
You’ll typically need:
-
Proof of Spanish tax residency
-
NIE (Foreigner ID Number)
-
Completed HMRC form
-
Supporting documents (e.g., pension statements)
I often help clients gather these and recommend where to submit—usually to HMRC first, then to the Spanish tax office (Agencia Tributaria) for validation.
When to seek professional tax advice
Always. Even if you understand the basics, tax laws change, and interpretation can vary by case. I work closely with trusted local tax advisers who understand cross-border issues and guide my clients with clarity and care.
Final Thoughts from a Local Property Expert
Plan ahead to avoid surprises
The UK–Spain tax treaty is a solid framework that works—if you understand and apply it correctly. My advice? Don’t wait until tax season to ask questions. From day one, I help my clients navigate not only property purchases but the financial realities that come with them.
A trusted agent makes all the difference
I’m not a tax lawyer, but after years working with British buyers, I know what questions to ask, what paperwork to gather, and where to point you for expert help. Buying a home abroad should be exciting, not stressful—and I’m here to make sure it stays that way.
