The UK National Living in Spain: Complete Tax and Estate Planning Guide (2026 Edition)
This is the definitive reference for the substantial British community living in Spain. With over 250,000 UK nationals officially resident in Spain (and many more spending significant time as non-residents), the British presence in Spain is one of the largest cross-border communities in Europe. The post-Brexit landscape has changed several aspects of the British-Spanish relationship without altering the fundamentals of property ownership, succession, taxation and lifestyle that make Spain attractive. This guide covers the complete framework: the UK domicile vs. UK residence vs. Spanish residence analysis; the Spain-UK Income Tax Treaty key articles; the application of UK pensions (state, occupational, private, government) under the treaty; the post-Brexit IRNR rate question (19% vs. 24%); UK CGT on Spanish property sales; UK IHT on the worldwide estate of UK-domiciled persons; Spanish IRPF and wealth tax for British residents; Spanish ISD with the Andalusian 99% reduction; making a Spanish will choosing English law under EU Regulation 650/2012; coordination between UK solicitor / accountant and Spanish lawyer / asesor fiscal. A tax adviser with UK-Spain expertise and a UK solicitor with international experience are both essential for substantial British expatriate families.
The British community in Spain: a structural overview
The British presence in Spain is among the largest and most established cross-border communities in Europe. Significant concentrations live in Costa del Sol (around 80,000-100,000 British residents in the broader Málaga province), Costa Blanca (around 60,000 in the Alicante area), Mallorca and the Balearics (around 20,000), the Canary Islands (around 30,000), and smaller communities elsewhere. The community spans retirees with second residences becoming permanent, working-age professionals relocating for lifestyle or career, families moving for the long term, and high-net-worth individuals investing in Spain.
Post-Brexit, the legal framework for British residents in Spain has changed but the substance of property ownership, business, family life and the fundamental Spain-UK relationship remains. UK nationals can still buy Spanish property freely, can still live in Spain (with appropriate visa for new arrivals), can still inherit and transmit Spanish property, can still benefit from the Spanish tax regime and the Spain-UK Tax Treaty. The principal post-Brexit changes are immigration (the 90-day Schengen limit for non-residents, the need for visa for residence) and certain procedural aspects (apostille of UK documents for use in Spain).
This guide is structured for both established British residents (who have been in Spain for years and need to manage ongoing tax compliance) and for new British movers (who are planning the transition from UK to Spain). The principles apply to all of them; the specific applications vary by individual circumstances.
UK domicile vs. UK residence vs. Spanish residence: the three concepts
The British expat in Spain operates in a framework of three distinct concepts that each have different effects. UK domicile is a concept of UK private international law that determines the law governing certain personal matters and, critically, the scope of UK inheritance tax. UK domicile is acquired by origin (typically the father's domicile at birth) or by choice (requiring physical presence in another jurisdiction plus the intention to remain permanently and indefinitely). UK domicile is "sticky" and is difficult to lose; many British expatriates retain UK domicile despite long Spanish residence.
UK residence (specifically UK tax residence) is determined by the Statutory Residence Test (SRT) introduced in 2013. The test combines automatic non-resident tests (less than 16 days in UK if previous UK resident; less than 46 days if not previously resident; full-time work abroad with limited UK days), automatic resident tests (183+ days in UK; UK home only; full-time work in UK), and sufficient ties tests (combining UK days with personal, family, accommodation and work ties). The test is complex and produces a definitive answer year by year.
Spanish residence is determined by the three Spanish tests: 183+ days in Spain in the calendar year; centre of economic interests in Spain; spouse and minor children habitually residing in Spain. For most British expatriates who have moved to Spain permanently, Spanish residence is clearly established and the UK residence is clearly lost. For British expatriates with continued substantial UK ties (UK property, UK family visited often, UK business), the residence analysis on both sides requires careful tracking and may produce dual residence with the tie-breaker rules of the Spain-UK Treaty applying.
The Spain-UK Income Tax Treaty (2013)
The Spain-UK Income Tax Treaty (2013, in force from 2014) is the central document for the cross-border tax analysis. It allocates taxing rights between the two countries and provides credit mechanisms for the avoidance of double taxation. The treaty is comprehensive and modern, covering business profits, employment income, dividends, interest, royalties, capital gains, pensions, government service, and includes anti-treaty-shopping provisions (limitation on benefits). Detail in our Spain-UK tax treaty guide.
Article 4 (residency tie-breaker): for individuals dual-resident under both countries' rules, the tie-breaker hierarchy is permanent home, centre of vital interests, habitual abode, nationality, mutual agreement. For most British expatriates with clear Spanish residence (permanent home in Spain, family in Spain), the tie-breaker confirms Spanish residence.
Article 10 (dividends): UK-source dividends to Spanish residents are subject to UK withholding at the treaty rate of 10% for portfolio investments (15% for substantial ownership in some cases). The Spanish resident receives credit for the UK withholding against Spanish tax on the dividend. Article 11 (interest): UK-source interest to Spanish residents is generally exempt from UK withholding (gross-up arrangements) and taxable only in Spain.
UK pensions: the central article for British expatriates
Article 17 (general pensions): UK pensions paid to Spanish residents are generally taxable only in Spain. This applies to UK State Pension, UK occupational pensions, and UK private pensions (SIPP, personal pensions). The procedure: the Spanish resident files Form Spain-Individual with HMRC requesting NT (No Tax) coding; HMRC pays the pension gross; the Spanish IRPF taxes the income at standard progressive rates.
Article 18 (government service pensions): pensions from UK government employment (civil service, NHS, armed forces, certain local government, etc.) are taxable only in the UK with one exception (only Spanish taxable if the recipient is a Spanish national and a Spanish resident). The UK applies UK income tax with the UK personal allowance. The Spanish IRPF does not tax the pension directly but includes it in the calculation of the marginal rate on other Spanish-taxable income (exemption with progression). For many British expatriates with civil service or NHS pensions, this is favorable: the UK basic rate (20%) on the pension is lower than the Spanish marginal rate (30-37%+) that would apply if Spain taxed the pension.
The UK tax-free lump sum (25% of UK pension pot, available from age 55) is NOT tax-free in Spain. A Spanish resident taking the lump sum faces full Spanish IRPF on the lump sum amount at marginal rates (potentially 40-45%+). The planning implication is significant: British nationals approaching the lump sum decision who plan to relocate to Spain should consider taking the lump sum before establishing Spanish residence (when UK no-tax rules apply) rather than after. The difference can be tens or hundreds of thousands of pounds.
The post-Brexit IRNR rate question
Before Brexit, UK residents owning Spanish property paid IRNR at 19% (EU/EEA rate). After Brexit, the literal application of the Spanish IRNR Act would put UK residents at 24% (non-EU/EEA rate). The 5 percentage point difference is material on substantial rental income or imputed income. The question of which rate actually applies post-Brexit has been the subject of debate.
In practice, Spain has continued to apply the 19% rate to UK residents in many cases, citing the spirit of the Spain-UK Treaty and the non-discrimination principle. The European Commission opened infringement proceedings on related questions and the Spanish position has been generally pro-UK rates. However, the application is case-by-case and not entirely settled. For UK residents with substantial Spanish rental income or capital gains, confirming the applicable rate with the asesor fiscal is important.
The 19% vs. 24% question also affects deductions. EU/EEA residents are entitled to deduct expenses related to Spanish rental income. Non-EU/EEA residents are not (or are only in limited circumstances). For UK residents with substantial deductible expenses (mortgage interest, maintenance, gestion, etc.), the application of EU/EEA treatment can produce significantly lower tax.
UK CGT on Spanish property sales
When a UK resident sells a Spanish property, UK CGT applies on the gain (UK residents are subject to UK CGT on worldwide property sales). The current UK CGT rates are 18% (basic rate) or 24% (higher rate) for residential property gains. The gain is calculated in pounds, converting the original cost at the historical rate and the sale proceeds at the current rate.
The Spanish IRNR (19% for UK as EU/EEA in practice, or 24% if strictly applied) on the same gain is creditable against the UK CGT under unilateral relief (TCGA 1992 s.277). The credit is limited to the UK CGT on the same gain. For most Spanish property sales by UK residents, the UK CGT is the binding constraint and the Spanish credit fully covers the Spanish tax, with some additional UK tax due.
Currency considerations matter. A property bought 20 years ago in pesetas (converted to euros) and sold today in euros may have a substantial Spanish gain (in euros) but a much smaller or even negative UK gain (in pounds), depending on the GBP/EUR rate evolution. The UK CGT is calculated on the GBP gain, not the EUR gain, so the two amounts can diverge substantially. Professional tax preparation handles the currency conversion properly.
UK IHT on the worldwide estate
UK Inheritance Tax (IHT) applies to the worldwide estate of UK-domiciled persons at the rate of 40% above the nil-rate band (currently £325,000, with possible additional residence nil-rate band of up to £175,000 for property left to descendants). The transfer to a UK-domiciled spouse is unlimited (no IHT); the transfer to a non-UK-domiciled spouse has a limited exemption (currently £325,000 above NRB).
For British expatriates retaining UK domicile (the typical case for the first 15+ years of Spanish residence and often beyond), the UK IHT applies to the worldwide estate including the Spanish property, Spanish bank accounts, Spanish business interests, and all other assets. The estate tax can be very substantial — for an estate of £2 million (modest for many British expatriates), the IHT can be £600,000+ above the NRB.
For long-term British expatriates in Spain who have genuinely intended to remain permanently, achieving non-UK domicile is theoretically possible after 15+ years of UK non-residence and clear evidence of permanent intent. The achievement eliminates UK IHT on the worldwide estate (only UK-situs assets remain subject). The analysis is complex and the evidence requirements are substantial; specialist UK solicitors handle these cases.
Spanish IRPF and wealth tax for British residents
A British national who becomes a Spanish tax resident is subject to Spanish IRPF on worldwide income at standard progressive rates (top marginal in most regions 45-47%). The Spanish wealth tax (Impuesto sobre el Patrimonio) applies on worldwide wealth above the regional threshold. For British expatriates with substantial worldwide wealth (UK property, investments, pensions), the Spanish wealth tax can be a substantial annual cost in regions where it applies fully (Catalonia, for example).
For new British arrivals in Spain meeting the criteria (5 years of non-residence prior, qualifying reason for relocation), the Beckham Law special regime can substantially reduce the Spanish tax burden for the first 6 years: 24% flat rate on Spanish-source income only; exemption of foreign-source income (including UK income); wealth tax only on Spanish-situs assets. For high-income or high-wealth British movers, this is very valuable.
The regional choice within Spain matters substantially. Madrid effectively eliminates wealth tax for residents (with Solidaridad de Grandes Fortunas filling the gap for very high wealth). Andalusia has reduced wealth tax significantly. For inheritance tax, Andalusia has the 99% reduction for direct family; Madrid similar; Valencia 99% since 2023. The choice of region of Spanish residence can save very substantial amounts annually for high-net-worth British expatriates.
Spanish ISD: Andalusian 99% and the practical reality
The Spanish Inheritance Tax (ISD) for British families inheriting Spanish property has been transformed by the regional reductions. In Andalusia, the 99% reduction for spouses, descendants and ascendants since 2019 has reduced the ISD on typical family inheritances to a few hundred euros. Madrid similar. Valencia 99% since 2023. For most Andalusian family inheritances of property by British heirs, the ISD is now a minor cost.
The UK IHT remains the principal succession tax for British families. For a UK-domiciled deceased, the UK IHT applies to the worldwide estate including the Spanish property. The ISD paid in Spain is creditable against the UK IHT under unilateral relief. For typical Andalusian inheritances where Spanish ISD is near zero, the credit is not material — the UK IHT is the binding tax cost.
The procedural side of a Spanish inheritance for a British family is more involved than the tax side. The six-month Spanish ISD deadline is strict and requires early engagement of a Spanish inheritance lawyer. The apostille of UK documents (death certificate, will, grant of probate) and sworn translations add weeks to the timeline. The notarial deed of acceptance, the inscription at the Land Registry, the closure of Spanish bank accounts — all are procedural steps that the Spanish lawyer handles under power of attorney from the British heirs.
Making a Spanish will choosing English law
A Spanish will choosing English law under article 22 of EU Regulation 650/2012 is essential for any British national with Spanish property. The choice avoids Spanish forced-heir rules (legítima) and applies English testamentary freedom to the Spanish estate. The cost is a single notarial appointment in Spain (€60-€120 notarial fee); the protection is substantial. The Spanish will only deals with Spanish assets and coordinates with the existing English will dealing with UK assets. Detail in our partner site making a Spanish will after Brexit.
Spain continues to apply EU Regulation 650/2012 to British testators even though the UK no longer participates in the regulation (Spain's application does not require reciprocity). The choice of English law is given full effect: Spanish forced-heir rules do not apply, the will is interpreted under English law (with English testamentary freedom), the disposition is exactly as the testator intended.
For British expatriates who have not made a Spanish will, the default rule applies: the law of habitual residence governs. For long-term Spanish residents, this is Spanish law with the legítima protecting the children's two-thirds share. Many British testators discover too late that the disposition they intended (everything to spouse, or to a single child, or to a charity) is overridden by Spanish forced-heir rules.
Practical compliance: the annual cycle
The annual tax compliance cycle for a British resident in Spain includes: January-March: preparation of UK Self Assessment if continuing UK obligations (UK rental income, UK CGT events, etc.); April-June: preparation of Spanish Model 100 (IRPF); first quarter: Spanish Model 720 if foreign assets exceed threshold; June 30: Spanish Model 100 due; July: UK Self Assessment due (extended to January for online filings); October 31: UK Self Assessment second payment on account; January 31: UK Self Assessment first payment for next year. Throughout: tracking of UK and Spanish day counts to confirm residence status.
Professional support typically includes both a UK accountant for the UK-side filings (Self Assessment, IHT planning, etc.) and a Spanish asesor fiscal for the Spanish-side filings (IRPF, wealth tax, Model 720). The coordination between the two professionals is essential, particularly for the foreign tax credit calculation and for events that cross jurisdictions (pension lump sums, property sales, business transactions, etc.).
The annual cost of professional support is typically £2,000-£5,000 for the UK side plus €2,000-€5,000 for the Spanish side, totaling roughly £/€4,000-£/€10,000 per year for a typical British expatriate family with moderate complexity. For high-net-worth families with complex international portfolios, the cost scales up but remains modest in relation to the value managed.
Special situations: UK property kept after move to Spain
Many British expatriates keep a UK property (former main residence) after moving to Spain — sometimes rented out, sometimes kept as a holiday/visit base. The UK property remains UK-situs for IHT purposes; rental income is taxable in the UK (with Spanish credit under treaty); eventual sale triggers UK CGT (with Spanish credit). The UK property also affects the SRT analysis (availability of UK home is a UK tie).
For UK property generating rental income, the British expatriate files UK Self Assessment for the rental income with the non-resident landlord scheme (NRL) administered by HMRC. The Spanish IRPF includes the rental income too (worldwide income) with credit for UK tax paid. The coordination between UK and Spanish filings is essential.
The eventual decision to sell the UK property triggers UK CGT (with the principal private residence relief potentially applying for periods when the property was the main residence; the rules for the post-2015 non-resident UK property CGT also apply). The Spanish IRPF taxes the gain too with credit for UK CGT. The decision to sell should be planned with both UK and Spanish tax advisers.
Pre-Brexit transitional considerations
Some British expatriates in Spain benefit from pre-Brexit transitional arrangements under the Withdrawal Agreement. British nationals who were legally resident in Spain before 31 December 2020 have specific protected status: they can continue to live, work, and study in Spain on the same basis as before Brexit; their family members can join them; their rights are protected indefinitely.
These pre-Brexit residents do not need the new visas (non-lucrative, digital nomad, etc.) for residence. They have a specific TIE (Tarjeta de Identidad de Extranjero) card with the indication "Acuerdo de Retirada" identifying them as Withdrawal Agreement beneficiaries. The legal protection is permanent.
For tax purposes, the pre-Brexit residents are in the same position as any Spanish resident — UK status no longer provides EU privileges for tax. The treaty Spain-UK applies as it always did. The day-to-day life is similar to pre-Brexit but with the new immigration framework for travel to other EU countries (no automatic freedom of movement; same as third-country national for other Schengen states beyond Spain).
Estate planning checklist for British expatriates
The estate planning checklist for British expatriates in Spain includes: assess UK domicile status; consider whether to actively work toward non-UK domicile (long-term decision); make Spanish will choosing English law under article 22; coordinate Spanish will with existing English will (or update English will to reflect Spanish residence); review beneficiary designations on pensions, life insurance, etc.; consider lifetime gifts to use UK IHT exemptions (annual £3,000, small gifts, marriage gifts, PETs); consider trust structures with careful Spanish analysis (UK trusts have complex Spanish treatment); review the inheritance tax planning every 5 years or after significant changes.
For high-net-worth British expatriates, additional planning considerations include: spouse exemption planning (timing of large gifts between spouses); business property relief and agricultural property relief planning; charitable giving with UK and Spanish tax benefits; family investment companies; offshore trusts with complex but potentially valuable applications. Each strategy requires specialist UK and Spanish input.
Action steps for British expatriates
First: confirm Spanish tax residency status (formally registered in Spain, > 183 days, centre of interests). Second: engage Spanish asesor fiscal and continue with UK accountant for dual filings. Third: apply the Beckham Law if eligible (within 6 months of Social Security registration). Fourth: file Form Spain-Individual with HMRC to obtain UK exemption on Article 17 pensions. Fifth: make a Spanish will choosing English law under article 22. Sixth: file Model 720 in the first Spanish residence year if thresholds met. Seventh: maintain dual compliance with annual filings (UK Self Assessment if continuing UK obligations, Spanish Model 100). Eighth: review periodically for UK domicile question, regional residence optimisation, and life-stage planning. For a full consultation, contact our team.
The British expatriate experience in Spain is mature, well-supported by professional infrastructure, and increasingly attractive in the post-Brexit landscape (when many of the supposed downsides have proven manageable in practice). With proper planning and ongoing professional support, the combination of Spanish lifestyle and proper tax compliance produces a satisfying long-term outcome for most British movers and their families.
