British expat tax in Spain 2026 — AEAT-side: IRNR, Beckham Law and Modelo 720 explained
British nationals in Spain face a tax compliance challenge that increased sharply with Brexit. Non-resident property owners saw their IRNR rate rise from 19% to 24% and lost the ability to deduct rental expenses. Residents discovered their UK ISAs generate fully taxable Spanish IRPF income. The Beckham Law offers a six-year tax window at 24% — but only if the Modelo 149 is filed within the non-extendable six-month deadline. And the Modelo 720 creates Spanish disclosure obligations for UK bank accounts, ISAs, shares, and property above €50,000 per category. Most British nationals are managing one or two of these obligations — few have a complete picture of all four simultaneously.

Specialised advice and personal service
BMC is the AEAT-side specialist for British nationals in Spain: we manage IRNR (Modelo 210/211), Beckham Law applications (Modelo 149/151), Modelo 720 for UK assets, and annual IRPF for Spanish residents. We do not advise on UK pension management (QROPS, SIPP) — that requires FCA authorisation. We coordinate with your FCA-regulated UK adviser so both sides of your position are coherent.
-
Post-Brexit British non-residents pay IRNR at 24% (not 19%) on Spanish-source income, with no rental expense deductions — a direct result of the UK's third-country status from 1 January 2021.
-
The UK-Spain DTT (BOE-A-2014-3057, signed 2013, in force 2014) remains fully operative post-Brexit and is the key instrument for preventing double taxation between both countries.
-
The Beckham Law (Article 93 LIRPF, Ley 28/2022) gives British professionals relocating to Spain a 24% flat rate for 6 years — with foreign-source income (UK salary from remote work, ISA returns, UK dividends) fully exempt. Apply via Modelo 149 within 6 months.
-
ISAs have no Spanish tax-free recognition — dividends and gains inside UK ISAs are fully taxable in Spanish IRPF at savings rates (19-28%).

The problem
British nationals in Spain face a tax compliance challenge that increased sharply with Brexit. Non-resident property owners saw their IRNR rate rise from 19% to 24% and lost the ability to deduct rental expenses. Residents discovered their UK ISAs generate fully taxable Spanish IRPF income.

Our solution
BMC is the AEAT-side specialist for British nationals in Spain: we manage IRNR (Modelo 210/211), Beckham Law applications (Modelo 149/151), Modelo 720 for UK assets, and annual IRPF for Spanish residents. We do not advise on UK pension management (QROPS, SIPP) — that requires FCA authorisation. We coordinate with your FCA-regulated UK adviser so both sides of your position are coherent.
How we do it
Tax status determination: IRNR vs IRPF vs Beckham
We determine your Spanish tax position: non-resident IRNR taxpayer (if you spend fewer than 183 days in Spain and your centre of economic interests is outside Spain), standard IRPF resident (if Spanish tax resident without Beckham eligibility), or Beckham Law regime (if relocating for work, entrepreneurship or Digital Nomad Visa and within the 6-month application window).
IRNR compliance: Modelo 210 and Modelo 211
For non-resident property owners: annual Modelo 210 for imputed income (own-use property); quarterly Modelo 210 for rental income (24% on gross, no deductions). For property sales: management of the 3% Modelo 211 retention and the capital gain Modelo 210 within the 3-month filing window.
Beckham Law application: Modelo 149
We verify Beckham eligibility (no Spanish tax residency in the previous 5 fiscal years, qualifying reason for relocation) and file Modelo 149 within the six-month deadline. We then manage Modelo 151 (annual Beckham declaration) for the duration of the regime.
Modelo 720: UK asset declaration
We identify your UK assets subject to declaration (bank accounts, ISAs, shares, property), verify the €50,000 thresholds per category, prepare and file Modelo 720 by the 31 March deadline. We also advise on supplementary declarations for new assets or significant value increases.
Coordination with your UK FCA adviser
We provide your FCA-regulated UK adviser with the Spanish AEAT position — what income is taxed in Spain, what DTT articles apply, what credits the UK can give — to ensure your UK self-assessment or HMRC position is coherent with your Spanish IRPF or Beckham regime filing.
I moved from London to Madrid in early 2024 to work remotely for a UK tech company. BMC verified my Beckham Law eligibility in 48 hours, filed the Modelo 149 within the window, and explained exactly what my ISA and UK share portfolio mean for the Modelo 720. Having a clear picture of both sides of my tax position for the first time is genuinely transformative.

Guide: British Expat Tax Spain 2026 — IRNR, Beckham, ISAs and Modelo 720 (PDF)
For British nationals in Spain, tax compliance with the AEAT spans a wider range of obligations than almost any other nationality group. This reflects both the scale of the British community in Spain (300,000+ registered residents) and the particular complexity created by Brexit — which transformed British nationals from EU citizens with seamless integration into third-country nationals with materially different tax treatment.
Understanding the AEAT side of your position is essential whether you are a non-resident property owner paying IRNR, a new resident considering the Beckham Law, an established resident managing the Modelo 720, or a UK employer trying to understand what a British employee’s Spanish tax position means for payroll. This guide maps all four scenarios.
The Brexit tax shift: from 19% EU rate to 24% third-country rate
Before 31 December 2020, British nationals in Spain enjoyed the same IRNR tax treatment as any EU/EEA citizen. The key provisions of the EU-EEA treatment:
- IRNR rate of 19% on Spanish-source income.
- For rental income: deduction of qualifying expenses (maintenance, community fees, insurance, mortgage interest, depreciation) before applying the 19% rate — effectively taxing only net rental profit.
- For property sales: 19% on the capital gain.
From 1 January 2021, British nationals became third-country nationals for Spanish tax purposes. The key changes:
- IRNR rate of 24% on Spanish-source income (Articles 24 and 25 LIRNR).
- For rental income: no expense deductions — the 24% applies to gross rental income, not net.
- For property sales: 24% on the capital gain (compared to 19% for EU/EEA residents).
The difference is significant. A British national renting out a Costa del Sol apartment for €15,000 per year, with qualifying expenses of €4,000, paid the following:
- Pre-Brexit (19% on net): (€15,000 - €4,000) × 19% = €2,090.
- Post-Brexit (24% on gross): €15,000 × 24% = €3,600.
An annual increase of €1,510 purely from Brexit — with no change in the underlying economic position.
IRNR for British non-resident property owners
Modelo 210: imputed income on own-use or vacant property
Every British non-resident property owner in Spain must file Modelo 210 once per year to declare imputed income on properties used personally or left vacant. The imputed income base is:
- 1.1% of the cadastral value, if the cadastral value was revised or updated within the last ten years.
- 2% of the cadastral value, if not revised in the past ten years.
The imputed income is then taxed at 24%. Example: apartment in Alicante with cadastral value of €80,000, last revised in 2018 → €80,000 × 1.1% = €880 × 24% = €211.20/year. This is small in absolute terms but omitting it generates an unresolved AEAT compliance gap that compounds with interest and late penalties.
Filing deadline: the Modelo 210 for imputed income (devengo: 31 December) can be filed at any point in the following calendar year.
Modelo 210: rental income (quarterly)
For British non-residents who let their Spanish property, Modelo 210 must be filed quarterly:
- Q1 (January-March rental): filed by 20 April.
- Q2 (April-June): filed by 20 July.
- Q3 (July-September): filed by 20 October.
- Q4 (October-December): filed by 20 January of the following year.
Base: Gross rental income for the quarter, at 24%, with no deductions of any kind. No management fees, no repairs, no community charges, no insurance, no mortgage interest, no depreciation. Gross = base.
Modelo 211: the 3% retention on property sales
When a non-resident sells Spanish property, the buyer has a statutory duty to withhold 3% of the total sale price and pay it to the AEAT via Modelo 211 within one month of the deed. This retention is not an additional tax — it is a withholding payment on account of the seller’s capital gain tax obligation.
The seller then has three months from the deed to file their own Modelo 210 declaring the actual capital gain. The IRNR on the gain is 24% of the net gain (sale price minus the indexed acquisition cost). If the 3% retention exceeds the 24% tax on the gain, the seller can claim a refund.
The AEAT processes Modelo 210 refund claims within 6-12 months typically. BMC manages the full process: coordinating the Modelo 211 with the notary, calculating the optimal acquisition cost indexation, filing the Modelo 210 on time, and pursuing any refund.
The UK-Spain Double Tax Treaty: your protection against double taxation
The UK-Spain DTT (BOE-A-2014-3057) is the foundation of the bilateral tax relationship. Signed on 14 March 2013, it replaced the previous 1975 convention and introduced modern provisions aligned with the OECD Model Tax Convention. It remains fully in force post-Brexit — as an international treaty, it is independent of EU membership.
Most relevant provisions for British nationals
Article 13 — Capital gains: Gains from the sale of Spanish immovable property may be taxed in Spain regardless of the seller’s country of residence. This means the UK cannot prevent Spain from taxing the capital gain on a Spanish property sale, even if you are UK-resident.
Article 4 — Tax residency and tie-breaker: Where an individual could be tax-resident in both the UK and Spain, the DTT provides a cascade of tie-breaker criteria: (1) permanent home; (2) centre of vital interests; (3) habitual abode; (4) nationality; (5) mutual agreement between HMRC and AEAT. This cascade determines which country has primary taxing rights for dual-residency situations.
Articles 17-18 — Pensions: Private pensions are generally taxed in the residence state (Spain, if Spanish-resident). State pensions are also generally taxed in the residence state for non-government employees. UK State Pension received by a Spanish resident is typically taxed in Spain under the DTT.
What the DTT does NOT cover: UK Inheritance Tax (IHT) and Spanish Impuesto sobre Sucesiones y Donaciones (ISD). There is no UK-Spain inheritance and gift tax convention. This means both UK IHT (40% on worldwide estate of UK-domiciled individuals) and Spanish ISD can potentially apply to the same estate. The interaction is managed through unilateral credit relief and pre-death planning.
The Beckham Law: the six-year opportunity for new arrivals
Why the Beckham Law matters for British professionals
The single most impactful tax planning decision available to British nationals relocating to Spain is whether to apply for the Beckham Law within the six-month window. For a professional earning €150,000 in Spanish employment:
- Standard IRPF (2026 Madrid rates): Effective rate approximately 43% → €64,500 tax.
- Beckham Law: 24% flat → €36,000 tax.
- Annual saving: approximately €28,500.
Compounded over six years, the total saving can be €150,000-200,000+ for a senior professional. For British tech workers, City of London professionals, consultants, and executives relocating to Madrid, Barcelona, or Marbella, this is a material consideration.
Qualifying categories under the reformed Ley 28/2022
The Ley 28/2022 de Startups (BOE-A-2022-21739) significantly broadened the Beckham Law’s scope:
- Employed workers — displaced by a Spanish company or a foreign company group member.
- Digital Nomads — remote workers for UK employers or clients, using the Digital Nomad Visa (DNV).
- Entrepreneurs — founders with the Spanish entrepreneur visa under Ley 14/2013.
- Highly qualified professionals — in startups or R&D/innovation entities (≥40% income from qualifying activities).
- Company directors — in Spanish entities where they hold less than 25% participation.
The six-month deadline: the most expensive missed deadline in Spanish tax law
The Modelo 149 must be filed within six months of Social Security registration (starting work). This is established in Article 116 of the IRPF Reglamento (RD 439/2007) and is absolutely non-extendable. If you miss it, you cannot access the Beckham regime for that relocation.
Common scenario that causes missed deadlines: arriving in Spain, starting work, delaying legal/tax advice, discovering the Beckham option after the window has closed. BMC tracks Beckham eligibility from the date of first client contact and flags the deadline prominently. The cost of missing it — forgoing 24% instead of up to 47% for six years — typically dwarfs the cost of professional fees by orders of magnitude.
Modelo 720 in practice: your UK assets under Spanish disclosure
The annual Modelo 720 (filed 1 January to 31 March for the previous year’s 31 December position) captures three categories of foreign assets:
Category 1 — Bank accounts: This includes all UK bank and building society current accounts, savings accounts, and Cash ISAs. Both the year-end balance and the Q4 average balance must be reported if either exceeds €50,000.
Category 2 — Securities and investment products: UK stock portfolios, ISAs (Stocks & Shares ISA, LISA, Innovative Finance ISA), mutual funds, OEICs, unit trusts. The total value of the portfolio at 31 December. Important: all types of ISA are included — the HMRC tax-free status of ISAs has zero relevance to the Modelo 720.
Category 3 — Immovable property: Properties in the UK, using the acquisition price or (for inherited properties) the inheritance deed value.
The CJEU reform: The original Modelo 720 penalty regime was ruled disproportionate by the Court of Justice of the EU in C-788/19 (January 2022). Spain subsequently amended the penalties — late filings without prior AEAT request now face proportionate fixed penalties rather than the previous confiscatory percentages. But the obligation to declare remains fully in force.
BMC advises on the Modelo 720 threshold calculations, prepares and files the declaration, and manages supplementary declarations where new UK assets are acquired or existing assets exceed the threshold for the first time.
