Spanish Tax for Expats 2026: Complete Guide to Income Tax, Wealth Tax & Residency Rules

Why Spanish Tax Matters for Expats

Spain is one of the most popular destinations in the world for British, American, Irish, and wider European expats. The appeal is obvious — warm weather, a lower cost of living in many areas, excellent healthcare, and an enviable quality of life. But moving to Spain — or even spending extended periods there — has significant tax implications that many expats underestimate or discover too late.

Spain's tax authority, the Agencia Tributaria (commonly called Hacienda), is one of the most sophisticated tax administrations in Europe. It has extensive data-sharing agreements with other countries' tax authorities, including HMRC in the UK, and participates in the OECD's Common Reporting Standard (CRS), which means it receives automatic information about bank accounts, investments, and other financial assets held by Spanish residents in overseas jurisdictions.

The consequences of getting Spanish tax wrong range from interest charges and surcharges on late filings to serious financial penalties and, in extreme cases, criminal proceedings. For expats who have moved to Spain without taking proper tax advice, discovering an unexpected liability — sometimes for multiple prior years — can be genuinely distressing.

The good news is that Spain's tax system, once understood, is navigable. Many expats find that their overall tax burden in Spain is comparable to — or even lower than — what they paid in the UK, particularly when personal allowances, deductions, and the Spain-UK Double Taxation Treaty are factored in. Others, particularly high earners, may benefit significantly from the Beckham Law.

This guide explains how the Spanish tax system works, what forms you need to file, what key deadlines apply, and how the major tax types — income tax, wealth tax, non-resident income tax, and local capital gains — affect expats. We also cover pensions, double taxation treaties, and practical steps for getting properly set up.

Throughout, we stress the same point: this is an overview, not advice. Spanish tax is complex, regionally variable, and changes regularly. Use this guide to understand the landscape — then speak to a qualified gestor or asesor fiscal before acting.

Tax Residency — The 183-Day Rule and How Spain Determines Your Status

The cornerstone of Spanish tax law, from an expat's perspective, is the concept of tax residency. Whether you are a Spanish tax resident determines everything: which taxes you pay, on what income, and at what rates. Getting this wrong — in either direction — can be extremely costly.

The Primary Test: 183 Days

Under Spanish law (Article 9 of the LIRPF — Ley del Impuesto sobre la Renta de las Personas Físicas), you are considered a Spanish tax resident for a given calendar year if you spend 183 or more days in Spain during that year. The calendar year runs from 1 January to 31 December.

Crucially, the days do not need to be consecutive. Hacienda counts every day you are physically present in Spain — including partial days in some interpretations. This means that if you spend, say, six months in Spain over the summer and a further month in the autumn, you may well exceed the threshold even if you consider yourself primarily based in the UK or elsewhere.

Spain explicitly excludes days of sporadic absences from the count — meaning that short trips outside Spain while you are resident do not interrupt your residency for tax purposes. The burden of proof to show that a claimed absence is more than sporadic generally falls on the taxpayer.

Secondary Tests: Centre of Economic Interests and Family Ties

Even if you spend fewer than 183 days in Spain, Hacienda can still treat you as a tax resident if either of the following applies:

• The main core of your economic activities and interests is directly or indirectly in Spain (for example, you own a business, have significant investments, or derive most of your income from Spain)
• Your spouse and/or dependent children habitually reside in Spain — Spanish law presumes that you are also resident unless you can prove otherwise

The family ties test in particular catches many expats off guard. If your partner and children live in Spain while you commute back to the UK for work, Hacienda may well take the view that Spain is your habitual place of residence.

HMRC and the UK Statutory Residence Test

Spain's rules do not exist in isolation. The UK has its own rules for determining tax residency — the Statutory Residence Test (SRT), introduced in 2013. The SRT is a detailed set of tests that looks at the number of days you spend in the UK, your ties to the UK (accommodation, family, work, and so on), and your pattern of presence over recent years.

It is entirely possible — and indeed common — for an expat to be considered resident in both the UK and Spain under each country's domestic rules. This is where the Spain-UK Double Taxation Treaty becomes important: it contains a series of tie-breaker rules to determine in which country you are ultimately treated as resident for treaty purposes, looking at factors such as where you have a permanent home, the centre of your vital interests, habitual abode, and nationality.

If you are leaving the UK, you should formally notify HMRC of your change of residency status (using form P85) and ensure you understand your final year of UK tax residency. You may have split-year treatment in both the year of departure from the UK and arrival in Spain, which affects how each country taxes your income in those transition years.

IRPF — Spanish Income Tax: How It Works and the 2026 Tax Bands

For Spanish tax residents, the main income tax is called IRPF — Impuesto sobre la Renta de las Personas Físicas, or Personal Income Tax. It is a progressive tax, meaning that higher slices of income are taxed at higher rates. It applies to your worldwide income, not just income arising in Spain.

The IRPF rate is made up of two components: a state (central government) rate and a regional (autonomous community) rate. Together, these produce the total effective rate you pay. The regional component is set by each autonomous community, so the total IRPF rate is not identical everywhere in Spain — though the differences are often modest at standard income levels.

2026 IRPF Tax Bands

The following table shows the 2026 income tax bands, including both the state rate and the approximate combined rate (state plus regional) based on typical regional rates. Your actual combined rate will depend on which autonomous community you live in.

These are marginal rates — each band applies only to the income within that bracket, not to your total income. So someone earning €40,000 pays 19% on the first €12,450, 24% on the next slice up to €20,200, 30% on income from €20,200 to €35,200, and 37% on the remaining €4,800 above €35,200.

Personal Allowances and Deductions

Spain provides several standard personal allowances that reduce your taxable income before the rates are applied:

• General personal allowance: €5,550 for taxpayers under 65; €6,700 for those aged 65–74; €8,100 for those aged 75 and over
• Employment income reduction: Additional reductions apply for earned income from employment, up to €5,565 for lower-earning employees
• Spouse and child allowances: Additional amounts if you have a dependent spouse on a low income, or dependent children under 25
• Disability allowances: Increased allowances for taxpayers or dependants with a recognised disability
• Pension contributions: Contributions to Spanish pension schemes (planes de pensiones) are generally deductible up to the lower of €1,500 per year or 30% of net employment income

Regional communities can also provide additional deductions for things such as renting your primary home, investment in local companies, and childcare costs. The practical effect is that the average effective tax rate most expats pay is significantly lower than the marginal rates suggest — particularly at lower to middle income levels.

What Counts as Taxable Income in Spain

As a Spanish tax resident, you are taxed on your worldwide income. This is arguably the most important concept for expats to grasp, because it means income arising outside Spain — from UK rental properties, Irish pensions, US dividends, or any other source — must be declared on your Spanish return. Simply not mentioning it is not an option; data sharing between tax authorities means Hacienda is increasingly likely to know about it anyway.

IRPF distinguishes between different types of income, which are taxed differently:

General Taxable Income (Renta General)

This category includes employment income (salary and benefits), self-employment income, rental income from letting property, and most pension income. It is taxed at the progressive IRPF rates described above.

• Salary and employment income: Gross salary, bonuses, benefits in kind, and employer-paid expenses are all included. An employment income reduction applies before rates are applied.
• Self-employment income: If you work as an autónomo (self-employed), your net business income — revenue minus allowable expenses — is subject to IRPF at progressive rates. You also pay social security contributions.
• Rental income: Income from letting property in Spain or abroad must be declared. For Spanish residential rentals, you can deduct expenses such as mortgage interest, community fees, insurance, maintenance, and depreciation. A 60% reduction applies to net rental income from habitual residence lettings in some circumstances.
• Pension income: Most pensions — Spanish, UK, or otherwise — are classed as general income and taxed at progressive IRPF rates. Government service pensions may be taxed differently under treaty rules.

Savings Income (Renta del Ahorro)

Savings income — which covers interest, dividends, and capital gains — is taxed at a separate, lower flat rate scale:

• €0 – €6,000: 19%
• €6,000 – €50,000: 21%
• €50,000 – €200,000: 23%
• €200,000 – €300,000: 27%
• Over €300,000: 28%

Dividends from Spanish and foreign companies are included in savings income. A small exemption (€1,500 historically, though this has been subject to change) has applied in some years — confirm the current position with your gestor.

Capital gains on the sale of assets — shares, funds, property, and so on — are taxed at savings income rates. The gain is calculated as sale proceeds minus acquisition cost (which can include certain expenses and inflation adjustments for property). Principal private residence exemption rules exist but differ from the UK system, so do not assume your experience in the UK will translate directly.

The Beckham Law — Régimen Especial de Trabajadores Desplazados

When footballer David Beckham moved to Real Madrid in 2003, Spain had recently introduced a favourable tax regime for high-earning individuals relocating to work in Spain. Whether or not the regime was designed with him in mind, it became universally known as the Beckham Law (Ley Beckham).

Formally, this is the Régimen Especial de Trabajadores Desplazados — the Special Regime for Displaced Workers. It was significantly reformed in 2023 as part of the Startup Act (Ley de Startups), broadening its scope and making it more accessible.

What Does It Offer?

Instead of paying progressive IRPF rates on worldwide income, qualifying individuals pay a flat rate of 24% on Spanish-source income up to €600,000. Income above €600,000 is taxed at 47%. Foreign-source income (other than certain employment income paid by non-Spanish employers) is generally excluded from the Spanish tax base entirely — you only pay Spanish tax on Spanish-source income.

The regime applies for the year of first registration and the following five years — six years in total. During this period, you are treated as a non-resident for IRPF purposes even though you are physically present in Spain, which is why the regime is sometimes described as a "non-resident status" for tax purposes.

Who Qualifies?

As of the 2023 reforms, the Beckham Law is available to individuals who:

• Have not been resident in Spain during the five preceding tax years
• Move to Spain as a result of: an employment contract with a Spanish company or a posting from a foreign employer to Spain; appointment as a director of a Spanish company (with restrictions where the appointee has a significant ownership stake); carrying out an economic activity in Spain as a self-employed person that qualifies as a "highly qualified" profession or is linked to a startup; or providing remote services as a digital nomad under the digital nomad visa
• Do not obtain income that would otherwise qualify as IRNR through a permanent establishment in Spain

Family members — a spouse and children under 25 — may also be able to elect into the regime if they meet the basic requirements, which can create significant household tax savings.

How to Apply

You must apply for the Beckham Law using Modelo 149, within six months of the date you first register with Spanish Social Security (your initial NIE registration date does not trigger the clock — it is social security registration). Missing this deadline means you lose the ability to elect into the regime entirely, with no exceptions.

Once approved, you file your annual tax return using Modelo 151 (rather than the standard Modelo 100 used by regular IRPF taxpayers).

Is It Right for You?

The Beckham Law is most beneficial for individuals with high incomes who would otherwise pay the upper IRPF rates, and for those with significant foreign-source income who can exclude it from the Spanish tax base. For lower earners, the standard IRPF system with its personal allowances may actually produce a lower tax bill than the flat 24% rate.

There are also important considerations around social security contributions, pension planning, wealth tax, and the treatment of income at the end of the six-year period that make professional advice essential before electing in.

UK Pensions in Spain — State Pension, Private Pensions, QROPS, and the Double Taxation Treaty

For the large number of British retirees living in Spain, understanding how their UK pension income is taxed is arguably the most important aspect of Spanish tax planning. The answers are generally clear — but the practical steps required are often missed.

The Spain-UK Double Taxation Treaty and Pensions

Under the Spain-UK Double Taxation Treaty (DTT), the general rule is that pensions and other similar remuneration paid to a resident of Spain in respect of past employment are taxable only in Spain. This means:

• UK private and occupational pensions received by Spanish tax residents should be taxed in Spain, not the UK
• The UK State Pension received by Spanish tax residents is taxable in Spain, not the UK
• HMRC should not deduct UK income tax from these payments once you are a Spanish tax resident — but it will not stop automatically; you need to formally notify HMRC and your pension provider

The exception is government service pensions — pensions paid in respect of service to the UK government (military, civil service, police, NHS, teachers in certain circumstances, etc.). Under most DTT provisions, these remain taxable in the UK regardless of where you live.

The UK State Pension in Spain

Many British retirees in Spain are pleasantly surprised to learn that their UK State Pension continues to be uprated each year by the triple lock — the annual increase is the highest of inflation, earnings growth, or 2.5%. Unlike British expats in some countries (notably Australia, Canada, and certain others), those living in Spain continue to receive the full triple lock uprating because Spain is a reciprocal social security agreement country.

The State Pension is paid gross by the UK Department for Work and Pensions (DWP) to non-resident claimants. You must declare it as income on your Spanish Modelo 100 return and pay Spanish IRPF on it at the applicable progressive rates. Since the State Pension is typically below the higher IRPF bands, and Spanish personal allowances may apply, many retirees find they pay little or no Spanish income tax on State Pension income alone.

Private Pensions, SIPPs, and Annuities

UK private pensions — whether defined contribution (DC) schemes, SIPPs (Self-Invested Personal Pensions), or annuities — are treated as general income under Spanish IRPF and taxed at progressive rates. The 25% tax-free lump sum entitlement under UK pension rules does not automatically translate to Spanish tax-free status; the Spanish tax treatment of lump sum pension withdrawals is complex and depends on factors including when contributions were made. Specialist advice is essential before making significant pension drawdown decisions as a Spanish resident.

QROPS — Qualifying Recognised Overseas Pension Schemes

Some British expats explore transferring their UK pension pot to a QROPS (Qualifying Recognised Overseas Pension Scheme) — an overseas pension scheme that meets HMRC's requirements. The potential attractions include avoiding UK inheritance tax on the pension, more flexible drawdown, and (in some cases) more favourable tax treatment in the country of residence.

However, QROPS transfers involve significant risks and costs. HMRC charges an overseas transfer charge of 25% on transfers where the member, scheme, and destination are not in the same country or EEA jurisdiction. Following Brexit, the EEA position for UK-to-EU transfers changed. Schemes marketed as QROPS have also been the subject of mis-selling, and many are illiquid or poorly regulated. The FCO, FCA, and financial advisers consistently caution that QROPS should only be considered with independent, specialist advice — not on the basis of unsolicited approaches.

Modelo 100 — The Annual Spanish Tax Return

Modelo 100 is the annual income tax return filed by Spanish tax residents under the IRPF system. If you are a Spanish tax resident in any given year, you will generally need to file Modelo 100 covering that year — though there are some exemptions for individuals with very low income below a threshold (generally €22,000 from a single payer, or €15,000 from multiple payers, as at 2026, subject to confirmation).

The Filing Window

Modelo 100 is filed annually for the previous calendar year. The filing window opens on 1 April and closes on 30 June. For example, your 2025 tax year return must be filed between 1 April and 30 June 2026. This is later than the UK's self-assessment deadline (31 January) and later than the US filing deadline (15 April), which surprises many expats.

If you opt to pay any tax owed by direct debit (domiciliación bancaria), the effective deadline is slightly earlier — typically around 25 June — to allow processing time.

How to File

Modelo 100 is filed digitally through the Agencia Tributaria's online portal (Sede Electrónica). You can file using a recognised digital certificate, a Cl@ve PIN (Spain's digital identity system), or through the Renta Web portal, which pulls in data already known to Hacienda (salary from Spanish employers, withholding taxes, etc.) and presents a draft (borrador) for you to review and amend.

Critically, the borrador will not automatically include foreign income, overseas assets, or income paid outside the Spanish payroll system. If you are an expat with UK rental income, a UK pension, foreign dividends, or other non-Spanish income sources, you must add these manually. Filing a borrador without adding foreign income is not a valid excuse — and Hacienda will have received information about many of these sources via international data exchange.

Key Deadlines and Forms Table

Modelo 720 — Overseas Asset Declaration

Modelo 720 is Spain's overseas asset declaration form — one of the most discussed, most feared, and most misunderstood requirements for expats. It is a reporting obligation, not a tax: filing Modelo 720 does not in itself create a tax liability. But failing to file it, or filing it incorrectly, can trigger severe consequences.

Who Must File

Spanish tax residents must file Modelo 720 if the total value of their overseas assets exceeds €50,000 in any one of the following three categories:

• Bank accounts and financial accounts held outside Spain
• Securities, shares, rights, life insurance policies, and annuities held with financial institutions outside Spain
• Real estate and rights over real estate located outside Spain

Each category is assessed independently. So if you have a UK bank account worth €60,000 and a UK property worth €300,000, you must declare in both the bank accounts category and the real estate category — even if your total overseas assets are €360,000, which is above €50,000 in each category.

The threshold is measured by the balance at 31 December of the relevant year, or the average balance of the final quarter of the year for bank accounts.

When to File and Re-File

Modelo 720 is filed for the first time when you first exceed the €50,000 threshold in a category. After that, you only need to re-file in subsequent years if the value in a category has increased by more than €20,000 compared to the previously declared figure, or if you acquire or dispose of assets. You do not need to file annually simply because the assets remain above the threshold.

The filing deadline is 31 March of the year following the tax year to which it relates.

Penalties and the EU Court Ruling

When Modelo 720 was introduced in 2012, the penalty regime was extraordinarily harsh. Failure to declare could result in penalties equal to 150% of the value of the undeclared assets — in effect confiscatory. These penalties were challenged and in January 2022, the Court of Justice of the European Union ruled that certain aspects of the penalty regime were disproportionate and incompatible with EU law.

Spain subsequently revised the rules, removing the most extreme penalties. However, the obligation to file remains fully in force. Late filing and inaccurate filing still attract formal fixed penalties. And where assets are discovered that should have been declared but were not, Hacienda may treat them as unjustified capital gains, taxable at IRPF rates with interest.

Patrimonio — Spanish Wealth Tax

Spain is one of the few countries in Europe that still levies a standalone wealth tax, known as Impuesto sobre el Patrimonio — commonly called Patrimonio. It applies to net assets (assets minus liabilities) above a certain threshold, held as at 31 December each year.

Who Pays It and How Is It Calculated?

Spanish tax residents are subject to Patrimonio on their worldwide net assets. Non-residents are subject to Patrimonio only on assets physically located in Spain.

The key exemptions and allowances:

• Personal allowance: €700,000 per individual (so €1.4 million for a couple filing separately)
• Primary home deduction: Up to €300,000 of the value of your main home in Spain is excluded from the taxable base
• Business assets: Ownership stakes in qualifying family businesses and certain unlisted shares may be exempt under specific conditions

The net result is that a single individual can hold up to approximately €1,000,000 in net assets (€700,000 allowance plus €300,000 home deduction) before Patrimonio becomes payable.

The national Patrimonio rates run from 0.2% on the first €167,129 of taxable wealth up to 3.5% above €10.7 million. However, the rates are set regionally, and communities can vary them substantially.

The Madrid Exception

The autonomous community of Madrid has granted a 100% bonus on Patrimonio, effectively reducing the charge to zero for residents of the Madrid region. This remains in force as at 2026. It is a significant factor in the decision of many wealthy expats about where in Spain to live.

Other Regional Variations

Catalonia, Valencia, and the Balearic Islands apply Patrimonio at or above the national rates, with some applying surcharges for very high wealth levels. Andalusia, Extremadura, and Murcia have in recent years offered their own bonuses or zero-rate provisions. The picture changes regularly as regional governments adjust their fiscal policies, so always check the current position for the specific autonomous community where you are resident.

Solidarity Tax on Large Fortunes

In 2022, the Spanish central government introduced a temporary Impuesto Temporal de Solidaridad de las Grandes Fortunas — a solidarity tax on large fortunes — applying to net wealth above €3 million. It was designed partly to prevent high-wealth individuals from escaping Patrimonio simply by living in Madrid or another zero-rate region. As at 2026, this tax continues to apply and has been subject to legal challenges by several autonomous communities. Its future is uncertain — another reason to take current, specialist advice.

Plusvalía Municipal — Local Capital Gains Tax on Property Sales

When you sell, inherit, or give away urban property in Spain, the relevant local council (ayuntamiento) levies a tax on the increase in the cadastral land value of the property over the period of ownership. This tax is called Plusvalía Municipal — formally the Impuesto sobre el Incremento del Valor de los Terrenos de Naturaleza Urbana (IIVTNU).

Note that this is a separate tax from the capital gains tax charged under IRPF on the profit from a property sale. Plusvalía municipal is a local tax on the cadastral land value increase; IRPF capital gains tax is a national tax on your actual profit. Both can apply to the same transaction.

How Is It Calculated?

Following a 2021 Constitutional Court ruling that the original calculation method was unconstitutional (as it could produce a tax liability even when no real gain had been made), Spain revised the rules. There are now two calculation methods, and the seller can choose whichever produces a lower liability:

• Objective method: Based on the cadastral value of the land multiplied by a coefficient set by the government based on the number of years of ownership
• Real gain method: Based on the actual difference between the sale price and the purchase price, applying the land component of the property (as opposed to the building component)

The tax rate applied to the calculated base is set by the local council, subject to a national maximum of 30%. Rates and coefficients vary by municipality.

The seller is generally responsible for paying Plusvalía municipal within 30 days of the sale. In the case of inheritance, it must be paid within six months (extendable to one year). If you are buying property, be aware that in some circumstances — particularly where the seller is a non-resident — the liability can pass to the buyer if the seller fails to pay.

IRNR — Non-Resident Income Tax for Property Owners

If you own property in Spain but are not a Spanish tax resident — for example, you have a holiday home there but spend less than 183 days in Spain per year — you are subject to the Impuesto sobre la Renta de No Residentes (IRNR), or Non-Resident Income Tax.

IRNR applies regardless of whether you actually rent out the property. Even if your Spanish property sits empty for the entire year, you are required to pay an imputed income tax based on the official cadastral value of the property.

Imputed Income (Property Not Rented Out)

If the property is not rented out, IRNR is calculated on an imputed (notional) income, which is:

• 1.1% of the cadastral value if the value has been revised within the past 10 years
• 2% of the cadastral value if the value has not been revised in the past 10 years

This imputed income figure is then taxed at the applicable IRNR rate:

• 19% for residents of EU countries and — following Brexit — UK nationals (this rate applies to UK residents as the UK-Spain DTT preserves EU-rate treatment for this purpose, but confirm with a gestor as this can be subject to change)
• 24% for residents of non-EU countries (including, potentially, UK nationals depending on current treaty interpretation)

The annual IRNR return for imputed income is filed using Modelo 210 and must be submitted by 31 December of the year following the relevant tax year.

Actual Rental Income

If you do rent out your Spanish property, IRNR is charged on the actual rental income received. EU residents can deduct expenses (mortgage interest, maintenance, management fees, etc.) before the 19% rate applies. Non-EU residents (and this is where the post-Brexit position for UK nationals is particularly important to clarify) may be charged 24% on gross rental income without deductions.

Rental income must be declared quarterly using Modelo 210, within 20 days of the end of each quarter.

Regional Tax Variations — Autonomous Communities

One of the most important — and most frequently overlooked — aspects of Spanish tax for expats is the extent to which your regional location within Spain affects your tax position. Spain's 17 autonomous communities have significant devolved tax powers, and the differences can be substantial.

Income Tax (IRPF) Regional Component

Each autonomous community sets its own regional component of IRPF rates and can also set its own regional personal allowances, deductions, and rebates. While the differences are not dramatic at standard income levels, they can become meaningful at higher income levels. Some communities have also introduced additional bands at the top end.

Wealth Tax (Patrimonio)

As noted above, the variation in Patrimonio across regions is dramatic. Madrid's 100% bonus, Andalusia's historic bonus, versus Catalonia and the Balearics applying full — or enhanced — rates means that where in Spain you choose to live can have a six-figure impact on your annual tax bill if your net assets are significant.

Inheritance and Gift Tax (Impuesto de Sucesiones y Donaciones)

Although not covered in detail in this guide, inheritance and gift tax is worth flagging as an area of similarly dramatic regional variation. Some communities (Madrid, Andalusia, Cantabria) offer near-zero effective rates for direct family members; others (Catalonia, Extremadura) apply significant rates. If estate planning is a consideration, regional location is highly material.

Practical Implications

For many expats, the choice of where to live in Spain is driven primarily by lifestyle — beach, city, climate, community. Tax should not be the sole driver. However, for those with substantial assets or high incomes, understanding the tax implications of different regions — and getting proper advice — is a valuable exercise. A qualified tax adviser who specialises in expat taxation can model the impact of different regional choices on your overall tax position.

Double Taxation — Spain's Treaties with the UK, USA, and Ireland

Double taxation arises when two countries both claim the right to tax the same income or asset. Spain has signed double taxation treaties (DTTs) with over 90 countries, with the aim of ensuring that individuals and businesses are not taxed twice on the same income.

The treaties work in one of two ways:

• Exemption method: One country exempts the income from its own tax and leaves the right to tax solely with the other country
• Credit method: Both countries retain the right to tax, but the country of residence gives a credit for tax already paid in the source country, capped at the amount of domestic tax that would have been due

Claiming Double Taxation Relief

In practice, claiming DTT relief requires you to:

• Declare all your worldwide income on your Spanish Modelo 100 return
• Include the foreign income and the tax already paid on it in the overseas country
• Claim the appropriate deduction or credit in the Spanish return
• In some cases, obtain a certificate of tax residency from Spain (available from Hacienda) to present to the overseas tax authority to prevent deduction of tax at source

For UK residents, notifying HMRC of your Spanish residency and requesting a coding change (using form Spain-Individual or the appropriate DT form) is essential to stop UK income tax being deducted from UK pensions and investment income at source.

The US situation deserves a special note: the US taxes its citizens on worldwide income regardless of where they live. American expats in Spain face a dual filing obligation — US and Spanish — and the interaction between the two systems is particularly complex. Specialist cross-border US-Spain tax advice is strongly recommended.

Practical Steps — Getting a Gestor and Setting Up Your Spanish Tax Affairs

Understanding the theory of Spanish tax is one thing. Getting properly set up is another. The following steps outline a typical process for a new expat arriving in Spain who needs to establish their tax position correctly.

1. Obtain your NIE Number

   Your NIE (Número de Identificación de Extranjero) is your foreign identification number, used for all dealings with Spanish authorities including tax. Without it, you cannot file tax returns, open bank accounts, or own property in Spain. Apply at a Spanish consulate in your home country before arriving, or at a police station in Spain.

2. Register your residency (Empadronamiento)

   Register your address with your local town hall (ayuntamiento) using the empadronamiento process. This is required for many services and is one of the formal markers of residency that Hacienda can use.

3. Notify HMRC (UK residents)

   Complete form P85 (Leaving the UK — getting your tax right) to notify HMRC that you are leaving. Request a NT (no tax) coding for any UK income sources — pension, rental, investment — that should be taxed in Spain under the DTT. This takes time; start early.

4. Open a Spanish bank account

   A Spanish bank account is essential for paying Spanish taxes, direct debits, and utility bills. Most banks require your NIE, passport, and proof of address.

5. Find a qualified gestor or asesor fiscal

   Ask for recommendations from the local expat community, international residents' groups, or your estate agent. Look for someone who specialises in expat taxation and ideally speaks your language. Check their credentials — a registered gestor administrativo (GA) should be registered with the Colegio Oficial de Gestores Administrativos.

6. Assess your Beckham Law eligibility

   If you are moving to Spain for work or as a qualified professional and have not been resident in Spain for the past five years, ask your gestor immediately whether you qualify for the Beckham Law. The six-month window from social security registration is immovable.

7. Identify your Modelo 720 obligations

   List all your overseas assets — bank accounts, investments, property — and their approximate values. Your gestor will advise whether you need to file Modelo 720 and will manage the filing for you.

8. File your first Modelo 100

   In the year after your first year of Spanish tax residency, file Modelo 100 for the previous year. Your gestor will handle this, but you need to provide full details of all worldwide income for the year.
