Every spring, Spain's tax authority (the AEAT) opens the income tax filing campaign — and for expats and foreign nationals living in Spain, this is often the most confusing time of the year. Which form do you file? Do you declare your worldwide income or just what you earned in Spain? Can you still use the Beckham Law? What happens to your savings account back home? This guide answers all of these questions clearly and in plain English, covering everything from determining your tax residency status to submitting your return online — with the 2026 filing campaign dates, current tax brackets, and the most common mistakes that cost international taxpayers money.
1. Tax Residency in Spain: The Foundation of Everything
Before you can file anything, you need to establish one fundamental fact: are you a Spanish tax resident or a non-resident? The answer determines which form you file, what income you declare, and which rates apply to you. Spanish tax law (Ley 35/2006, LIRPF) establishes three independent tests. Meeting any single one of them makes you a full tax resident for the entire calendar year — there is no pro-rata or partial-year residence under Spanish law.
The 183-day rule
If you were physically present in Spain for more than 183 days during 2025, you are a Spanish tax resident for that year. Days of temporary absence count as days in Spain unless you can demonstrate genuine tax residency in another country through an official certificate of fiscal residence from that country’s tax authority. Counting days includes every day you set foot in Spain, regardless of the reason for your presence.
Practical note for expats with dual homes: If you split your time between Spain and another country and neither exceeds 183 days, you are not automatically a Spanish tax resident on this test — but you may still trigger the tests below.
Centre of vital or economic interests
Even if you spent fewer than 183 days in Spain, you may still qualify as a Spanish tax resident if Spain is where the core of your economic interests is located. This means the country where you have your main business activity, your most significant assets, or your primary source of income. This test is particularly relevant for freelancers and remote workers who spend time across multiple countries but whose principal client, employer, or business revenue originates in Spain.
The family ties presumption
If your legally non-separated spouse and/or dependent minor children are Spanish tax residents, the AEAT presumes you are too. This presumption is rebuttable — you can argue against it with documentation — but the burden of proof rests with you, not the tax authority. Separating from your Spanish-based family without formalising the legal separation does not remove this presumption.
What residency means in practice
| Your status | What you declare | Form |
|---|---|---|
| Tax resident (standard) | Worldwide income — salary, rental, dividends, pensions, capital gains, regardless of country of origin | Modelo 100 |
| Beckham Law beneficiary | Spanish-source income only, flat 24% rate | Modelo 151 |
| Non-resident | Spanish-source income only, per-transaction | Modelo 210 |
The moment you become a Spanish tax resident, all income from all countries enters the Spanish tax base. Your Australian superannuation contribution, your UK rental property income, your US brokerage dividends — all of it must be declared on your Spanish return. Double taxation treaties prevent you from paying tax twice on the same income, but declaring it is obligatory regardless.
When do you become a tax resident?
Spain operates on a calendar-year basis. You become a tax resident for a given year on 1 January of that year if you met any of the three tests during the prior year — or, practically, at the point during the year when you cross the 183-day threshold. This has an important implication: if you moved to Spain in, say, October 2024 and quickly reached 183 days, you were already a Spanish tax resident for all of 2024, which means income earned in January 2024 — before you even arrived — falls within the Spanish tax base.
2. Who Must File — and Why You Might Want to File Even if You Don’t Have To
Mandatory filing thresholds
As a Spanish tax resident in 2025, you are obligated to file an IRPF return (modelo 100) if any of the following apply:
- Employment income from a single employer exceeds €22,000 gross.
- Employment income from multiple employers where the second and subsequent employers paid more than €1,500 and total employment income exceeds €15,876.
- Capital gains or losses exceeding €1,600.
- Imputed rental income (rentas imputadas de inmuebles) and other income exceeding €1,000 in total.
- You received the Ingreso Mínimo Vital (minimum living income benefit).
- You made contributions to protected assets for disabled individuals.
- You are subject to wealth tax.
Why filing below the threshold can benefit you
Even if you fall beneath all the thresholds above, you may be better off filing voluntarily. This is the case when:
- Your employer applied income tax withholdings (retenciones) throughout the year — filing is the only way to recover overpaid withholdings as a refund.
- You had significant deductible expenses that would result in a negative tax result.
- You are building up a track record for mortgage applications or visa renewals that require tax return certificates (certificado de la declaración de la renta).
- You need to report foreign assets via modelo 720 or modelo 721, which are always mandatory regardless of your IRPF obligation.
3. IRPF Tax Brackets for 2026 (2025 Income)
Spain’s IRPF is a progressive tax applied to the base imponible general — your general income base, which includes employment income, rental income, and income from economic activities. There is a separate scale for savings income (base imponible del ahorro), which covers dividends, interest, and capital gains.
General income scale (estado + comunidad autónoma)
The following are the national state brackets. Each autonomous community (Comunidad Autónoma) applies its own complementary scale, which adds roughly a similar amount. The combined effective rates shown here are approximations — your actual rate depends on your region of residence.
| Taxable income (€) | State rate | Approx. combined rate (ES average) |
|---|---|---|
| 0 – 12,450 | 9.5% | ~19% |
| 12,451 – 20,200 | 12% | ~24% |
| 20,201 – 35,200 | 15% | ~30% |
| 35,201 – 60,000 | 18.5% | ~37% |
| 60,001 – 300,000 | 22.5% | ~45% |
| Above 300,000 | 24.5% | ~47% |
The top combined rate of 47% (and higher in some regions, such as Catalonia’s 50%) applies only to income above €60,000 at the national level, with some communities having additional brackets.
Personal and family allowances reduce the taxable base before these rates apply. The general personal allowance is €5,550, rising to €6,700 for taxpayers aged 65+ and €8,100 for those aged 75+. Each dependent child reduces the taxable base by between €2,400 and €4,500 depending on birth order, with additional allowances for disabled dependants.
Savings income scale
Capital gains, dividends, interest, and income from insurance products are taxed on a separate, lower scale:
| Savings income (€) | Tax rate |
|---|---|
| 0 – 6,000 | 19% |
| 6,001 – 50,000 | 21% |
| 50,001 – 200,000 | 23% |
| 200,001 – 300,000 | 27% |
| Above 300,000 | 28% |
These rates apply uniformly across all autonomous communities — savings income is not subject to regional supplementary rates.
4. The Beckham Law Option: 24% Flat Rate for New Residents
If you relocated to Spain for work within the last six years and had not been a Spanish tax resident in the prior five years, you may qualify for the Special Regime for Inbound Workers — universally known as the Beckham Law after the footballer who used it when he joined Real Madrid. This is by far the most significant tax advantage available to expats moving to Spain, and it is worth spending a moment understanding it before assuming you must pay progressive rates.
What the Beckham Law gives you
- A flat 24% rate on Spanish-source employment and professional income up to €600,000 (income above that threshold is taxed at 47%).
- Exclusion of foreign-source income from the Spanish tax base for the first six years of residence.
- Savings income (dividends, interest, capital gains) taxed at the standard savings rates (19–28%).
For a senior executive earning €150,000, the Beckham Law typically saves between €25,000 and €40,000 per year compared to the standard progressive scale.
Who qualifies
- You have not been a Spanish tax resident in the five years immediately preceding your move to Spain.
- You relocated to Spain to perform a specific employment activity under a contract with a Spanish company (including being a director of a Spanish entity you do not hold more than 25% of), or to carry out remote work for a non-Spanish employer, or as an entrepreneur under the Startup Law framework.
- You apply within 6 months of registering with Spanish Social Security (or your first listing with the Spanish tax authority).
The application is filed using modelo 149. Once approved by the AEAT, you file annually on modelo 151 instead of the standard modelo 100. The regime lasts for the year of election and the following five years — a maximum of six tax periods.
For a full analysis of eligibility, the application process, and interaction with specific income types (RSUs, carried interest, pensions), see our detailed guide: Beckham Law Spain: Complete 2026 Guide and our side-by-side comparison Beckham Law vs Standard IRPF: Which is Better for You?.
Critical warning: Missing the 6-month application window permanently disqualifies you from using the regime for that relocation. If you arrived in Spain in 2024 or 2025 and have not yet applied, contact a tax adviser immediately.
5. Step-by-Step: How to File Your Spanish Tax Return
Step 1 — Obtain your digital identification
To file online through the AEAT’s Renta WEB platform, you need one of three digital identity methods:
- Certificado digital (digital certificate): A cryptographic certificate issued by the FNMT (Spanish national mint) or your regional CA. Valid for 4 years, usable from any device with the certificate installed.
- Cl@ve PIN: A one-time PIN-based system linked to your NIE/DNI and a phone number. Simpler to obtain, valid for a single session.
- Cl@ve Permanente: A longer-lived version of Cl@ve, requiring prior in-person registration at an AEAT office or consulate.
As an expat, you need your NIE (Número de Identificación de Extranjero) before any of these can be obtained. If you do not yet have a digital certificate, the Cl@ve PIN is the fastest route — you can request it online with your NIE and passport and receive the PIN by post within a few days.
Step 2 — Access the AEAT Renta WEB platform
Go to sede.agenciatributaria.gob.es and navigate to “Renta 2025” under the “IRPF” section. The platform opens each year around 2 April. Log in with your digital certificate or Cl@ve credentials.
Step 3 — Review the draft return (borrador)
The AEAT pre-populates a draft return (borrador) using data from your employer’s annual withholding certificate (modelo 190), Spanish bank statements reported by financial institutions, and property registry data. For many employees with simple situations, the draft is largely accurate.
However, for expats, the draft is almost never complete. It will not include:
- Foreign income of any kind.
- Foreign bank account interest not reported to the AEAT.
- Property income from outside Spain.
- Deductions you are entitled to but have not previously claimed.
- Corrections needed for the double taxation relief (deducción por doble imposición internacional).
Never accept the draft without reviewing it, especially in your first years as a Spanish tax resident.
Step 4 — Add, correct, and complete
Work through each section of Renta WEB systematically:
- Personal data and family situation — verify your address (for determining your autonomous community and its applicable rates), civil status, and dependants.
- Employment income — verify the figure matches your employer’s annual certificate (certificado de retenciones). If you have income from multiple countries, add each separately.
- Capital gains and losses — import data from Spanish brokers/banks (the platform can connect to some automatically). Add foreign investments manually.
- Rental income — add income from Spanish properties and, if a tax resident, foreign properties.
- Savings income — dividends, interest, redemptions.
- Deductions — apply double taxation relief, pension deductions, regional deductions, and any housing deductions you are entitled to.
Step 5 — Submit
When the return is complete and the result (to pay or to refund) is calculated, confirm and submit through the platform. You will receive a NRC (Número de Referencia Completo) as proof of submission. If the result is a tax payment, you can pay by direct debit, bank transfer, or card. If the result is a refund, the AEAT processes payments within 6 months of the filing deadline.
6. Common Deductions Expats Often Miss
Double taxation relief (deducción por doble imposición internacional)
If you paid income tax in another country on income that is also declared in Spain, you are entitled to a credit against your Spanish tax liability for the foreign tax paid. The credit is limited to the lower of: (a) the foreign tax effectively paid, or (b) the Spanish tax that would apply to that same income at the Spanish average effective rate. This deduction is entered in the “Deducciones por doble imposición” section of Renta WEB and requires documentation of the foreign tax paid (typically a tax certificate from the foreign authority).
Pension contributions (planes de pensiones)
Contributions to Spanish private pension plans (planes de pensiones) are deductible from the general taxable base up to the lesser of €1,500 per year (individual plan) or 30% of earned income. The limit rises to €8,500 if your employer also contributes to a company pension plan on your behalf. For expats contributing to foreign pension schemes, the deductibility depends on whether the scheme qualifies under Spanish law — specific analysis is needed for UK SIPPs, US 401(k)s, and similar foreign vehicles.
Housing deduction (transitory regime)
A legacy deduction for the purchase of a habitual residence (deducción por inversión en vivienda habitual) was abolished in 2013, but a transitory regime maintains the deduction for those who purchased before 2013. If you bought a Spanish property before that date and it is your habitual residence, you can still deduct 15% of mortgage payments (principal and interest) up to €9,040 per year per taxpayer.
Regional deductions
Each autonomous community offers its own deductions on top of the state deductions. Common examples include:
- Deductions for renting a habitual residence (the tenant, not the landlord).
- Deductions for birth, adoption, or large families.
- Deductions for renewable energy installations.
- Deductions for cultural, sports, or educational donations.
These vary widely by region. If you live in Madrid, Andalusia, or the Basque Country, there may be meaningful deductions that apply to your situation.
Imputed rent on second properties
A somewhat counterintuitive obligation: if you own a Spanish property that is not your habitual residence and you did not rent it out, the AEAT imputes a notional rental income of 1.1%–2% of the cadastral value of the property. This is added to your general income base. Many expats who buy a holiday home in Spain are unaware of this rule and miss declaring it — which creates an underpayment that triggers penalties when discovered.
7. Worldwide Income: What Must Be Declared
Foreign bank accounts
Interest earned on bank accounts held outside Spain must be included in your savings income. Spanish financial institutions report account data to the AEAT automatically, but foreign banks do not. You are responsible for adding this income manually.
If the aggregate value of your foreign bank accounts, securities, insurance policies, or real estate outside Spain exceeded €50,000 at any point during 2025, you were also obligated to file modelo 720 (foreign assets declaration) by 31 March 2026. This is a purely informational declaration — it does not generate a tax payment — but penalties for non-compliance are severe (€5,000 per unreported item, minimum €10,000 per category, with no statute of limitations for the assets themselves).
Cryptocurrency (Modelo 721)
Since 2023, holders of cryptocurrency and other virtual assets with a value exceeding €50,000 at any point during the year must file modelo 721, the virtual asset equivalent of modelo 720. This applies to crypto held on both Spanish and foreign exchanges and wallets. Additionally, capital gains and losses from crypto disposals must be reported on your IRPF return in the capital gains section.
Foreign property
Rental income from property located outside Spain must be declared as part of your worldwide income on modelo 100, offset by the double taxation relief for any tax paid in the country where the property is located. If the property was not rented but simply owned, no imputed rent applies to foreign property (unlike Spanish second properties).
Foreign pensions and annuities
Pensions received from foreign states or private schemes are generally taxable in Spain as employment income, subject to double taxation treaty provisions. The UK/Spain treaty, the US/Spain treaty, and the Germany/Spain treaty each handle pensions differently, and the specific article governing pensions in each treaty determines whether Spain has primary taxing rights. If you receive a foreign pension, professional advice is essential before filing.
8. Common Mistakes Expats Make When Filing in Spain
Mistake 1: Not filing in the first year of residency
The most expensive mistake. Many expats arrive in Spain mid-year, spend more than 183 days, and are unaware they became Spanish tax residents. The following April, no filing reminder arrives (you are not on the AEAT’s mailing list yet), so they miss the deadline entirely. The AEAT discovers this 2–5 years later during a routine review, assesses back taxes, interest, and late filing surcharges (recargos por presentación extemporánea) of 5–20%, plus potential penalties.
What to do: If you moved to Spain in 2024 or 2025 and have not filed, assess your residency status immediately. Voluntary late filing — before the AEAT notifies you — attracts a much lower surcharge than filing after a formal notification.
Mistake 2: Confirming the draft without reviewing it
Renta WEB makes it very easy to click “confirm draft.” The AEAT encourages this. But the borrador is populated only from data Spanish entities have reported about you — it knows nothing about your UK dividend account, your Irish rental flat, or the €30,000 capital gain you made on US equities. Confirming an incomplete draft is equivalent to submitting a fraudulent return, regardless of intent.
Mistake 3: Forgetting the Beckham Law application window
The 6-month window runs from the date of your Social Security registration (alta en la Seguridad Social) or the first entry in the AEAT’s census. It is an absolute deadline with no exceptions. Missing it — often because no one told you it existed — means you lose the regime for that entire period of Spanish residence. For a professional earning €120,000 per year, this is a six-year loss of approximately €150,000 in potential tax savings.
Mistake 4: Not reporting foreign assets on modelo 720/721
The Spanish foreign assets declaration is not a tax — but penalties for not filing it are among the harshest in European tax law. The Spanish Constitutional Court partially struck down the original penalty regime in 2022, but the obligation to file and significant penalties for non-compliance remain. If you have foreign accounts, securities, property, or crypto above the thresholds, file modelo 720 and/or 721 by 31 March each year.
Mistake 5: Claiming the habitual residence exemption on a property you did not actually occupy
Capital gains from the sale of a habitual residence (vivienda habitual) are exempt from IRPF if proceeds are reinvested in another habitual residence within two years, or if the seller is over 65. Many expats attempt to apply this exemption on properties that were not, in fact, their habitual residence — they were let on Airbnb, used as holiday homes, or occupied by family members. The AEAT cross-references empadronamiento (padrón municipal) data, utility records, and rental platforms when auditing these exemptions.
Mistake 6: Missing the split-payment election for tax-due returns
If your return results in a payment, you can elect to split it: 60% at filing and 40% by 5 November, with no interest or surcharge on the deferred portion. Many first-time filers are unaware of this option and pay 100% upfront unnecessarily. The election must be made at the time of filing — you cannot request it after the fact.
9. Non-Residents vs. Tax Residents: A Quick Comparison
If you have not met any of the tax residency tests and you own Spanish property, earn Spanish rental income, or have sold a Spanish asset, you are a non-resident subject to Spanish IRNR (Impuesto sobre la Renta de No Residentes), filed on modelo 210.
| Tax resident (Modelo 100) | Non-resident (Modelo 210) | |
|---|---|---|
| Income in scope | Worldwide income | Spanish-source income only |
| Tax rate | Progressive 19–47% | 24% (EU/EEA residents: 19%) |
| Filing period | April–June, annual | Per transaction or quarterly |
| Deductions allowed | Full set | Limited (EU/EEA residents: full expenses) |
| Rental income | Deduct all expenses | Deduct expenses (EU/EEA only) |
Non-resident owners of Spanish property have specific quarterly filing obligations for rental income and an annual obligation to declare imputed income on vacant properties. For a complete guide to non-resident obligations, see our article on filing modelo 210 as a non-resident property owner in Spain.
10. Digital Nomad Visa Holders: Special Considerations
Spain’s Digital Nomad Visa (Visado para Teletrabajadores de Carácter Internacional, Law 28/2022) allows remote workers employed by non-Spanish companies to live in Spain legally. Its tax implications are significant and often misunderstood.
Tax residency still applies
Holding a Digital Nomad Visa does not exempt you from Spanish tax residency rules. If you spend more than 183 days in Spain, you become a Spanish tax resident regardless of the visa category you entered on. There is no special “exempt” status for digital nomads.
The Beckham Law connection
The Startup Law (which introduced the digital nomad visa) also extended the Beckham Law to cover qualifying remote workers. A digital nomad who moves to Spain under this visa and meets the eligibility criteria can apply for the Beckham Law regime — paying 24% on Spanish-source income while excluding foreign-source remote work income from the Spanish tax base for up to six years.
Key condition: The activity for the non-Spanish employer must be remote and genuinely performed from Spain. The employer must be a non-Spanish entity. You cannot apply the Beckham Law as a digital nomad if you are freelancing for Spanish clients or operating a Spanish company.
Non-EU employers and Social Security
Digital nomads employed by non-EU companies may be exempt from Spanish Social Security contributions under the terms of applicable bilateral social security agreements. However, Social Security and tax residency are separate regimes — being exempt from Social Security does not affect your tax obligations.

Conclusion: Getting Your Spanish Tax Filing Right
Filing income tax in Spain as an expat is more complex than in most countries, but it is entirely manageable with the right preparation. The key decisions — whether you are a tax resident, whether you qualify for the Beckham Law, and whether your foreign assets trigger modelo 720/721 obligations — should be made at the start of the tax year, not the night before the June deadline.
The most important thing to understand is that early planning saves money. The Beckham Law window closes 6 months after arrival. The modelo 720 deadline is 31 March. Voluntary late filing attracts a 5% surcharge; filing after AEAT notification can reach 20% plus penalties. None of these are recoverable mistakes if caught late enough.
