How many days can I spend in Spain before becoming tax resident?

183 days in a calendar year (1 January to 31 December) is the main threshold. Sporadic absences don't break the count unless you can prove tax residency elsewhere. You can also be deemed resident if Spain is the centre of your economic interests, even with fewer days.

Does the Beckham Law apply to digital nomads?

Yes, since the 2022 Ley de Startups reforms. Digital nomads on the Spanish Digital Nomad Visa can now apply for the Beckham Law regime, provided they haven't been Spanish tax residents in the previous five years and apply within six months of their Social Security registration. They pay a flat 24% on Spanish-sourced income up to €600,000, with foreign income exempt.

What is Modelo 720 and who has to file it?

Modelo 720 is an informational declaration of assets held abroad. Spanish tax residents must file it if they hold bank accounts, investments, real estate, or certain insurance products outside Spain with a total value exceeding €50,000 in any single category. You file once on becoming resident, then again if any category's value rises by more than €20,000 in a subsequent year.

Can I avoid Spanish tax by keeping my bank account in the UK?

No. Tax residency is determined by where you live, not where your money is held. Once you're a Spanish tax resident, you owe Spanish tax on your worldwide income regardless of which country your accounts are in. Spain and the UK automatically exchange financial information under international agreements, so undeclared foreign accounts are increasingly visible to the Agencia Tributaria.

How do I apply for the Beckham Law regime?

File Modelo 149 with the Agencia Tributaria within six months of registering with Spanish Social Security (or within six months of getting your Digital Nomad Visa). You then file annual returns using Modelo 151 instead of the standard Modelo 100. Missing the six-month window means you cannot apply retroactively, so don't delay.

If I leave Spain, do I still owe Spanish tax?

You owe tax for the portion of the year you were resident, and must file a final return covering that period. Residency ends when you spend fewer than 183 days in Spain in the new calendar year. Spain also has an exit tax on large unrealised capital gains for those leaving with very high-value portfolios, though this affects relatively few people.

Do I need a gestor to file my Spanish tax return?

You're not legally required to use one, but most expats should — especially in their first year, or if they have foreign income, assets abroad, or are applying for the Beckham Law. A competent asesor fiscal typically charges €200–€500 for a straightforward return, more for complex cases. Errors on self-filed returns can trigger audits and penalty surcharges that cost far more.

How to Become Tax Resident in Spain: What You Actually Owe

How to Become Tax Resident in Spain — and What Happens Next

Spend more than 183 days in Spain in a calendar year and you are, in the eyes of the Agencia Tributaria, a Spanish tax resident. That's the bluntest version of the rule. It doesn't matter whether you've registered on the padrón, applied for a TIE card, or even intended to stay that long. The clock runs from 1 January to 31 December, and once you cross that threshold, Spain considers your worldwide income fair game.

There's a second trigger people often miss: even if you spend fewer than 183 days here, you can still be deemed tax resident if Spain is the "centre of your economic interests" — meaning this is where you earn most of your money, or where a spouse and dependent children live. In practice, this second rule catches fewer people, but it's worth knowing it exists.

The 183-Day Rule in Practice

The count includes sporadic absences unless you can prove you're a tax resident somewhere else. That last bit is important. If you're a British citizen who moved to Barcelona in March 2025, spent the summer partly in the UK, and returned in September, you need to tally every day carefully. Days of arrival and departure both count. Spain doesn't stamp passports for EU travel, so if you're an EU citizen, the burden of proof is effectively on you to demonstrate you weren't here.

For British nationals post-Brexit, entering on a passport means you're logged at the border, which makes the count cleaner — but also harder to dispute if HMRC and the Agencia Tributaria ever compare notes, which they increasingly do through automatic exchange-of-information agreements.

Once you're tax resident, you file an annual income tax return called the declaración de la renta (IRPF), typically between April and the end of June for the previous calendar year. Miss it and the penalties start immediately — a 1% surcharge per month, rising steeply after 12 months.

IRPF: What the Rates Actually Look Like

Spain uses a progressive income tax system split between the national government and the regional government of whichever autonomous community you live in. The combined rates as of 2026 look roughly like this:

Up to €12,450: around 19%
€12,450–€20,200: around 24%
€20,200–€35,200: around 30%
€35,200–€60,000: around 37%
€60,000–€300,000: around 45–47%
Above €300,000: up to 47% nationally, with some regions adding more

These are approximate combined figures — the exact rate depends on where you live. The Basque Country and Navarra operate their own tax systems (régimen foral) and have different bands. Andalusia has made some cuts to its regional portion in recent years. Catalonia is generally one of the higher-tax regions. Always check the specific rates for your autonomous community, or get a gestor to run the numbers.

You also get a personal allowance — the mínimo personal — of €5,550 for most people, rising if you're over 65 or have dependants. This comes off your taxable income before the rates apply.

Savings and Investment Income

Dividends, interest, and capital gains are taxed separately under the base del ahorro (savings base), at rates that are lower than income tax:

Up to €6,000: 19%
€6,000–€50,000: 21%
€50,000–€200,000: 23%
€200,000–€300,000: 27%
Above €300,000: 28%

If you're retired and living off a UK pension, a portfolio, or rental income from property abroad, this is the bracket that matters most to you. Spain has double-taxation treaties with most countries (the UK included), so you generally won't be taxed twice on the same income — but you do need to declare it all, and the treaty determines who taxes what.

The Beckham Law: The Expat Tax Regime Worth Knowing

Officially called the Régimen Especial para Trabajadores Desplazados (Special Regime for Posted Workers), but universally known as the Beckham Law after the footballer who famously used it when he joined Real Madrid in 2003, this is the scheme that makes Spain genuinely competitive for high-earning international workers.

Under the Beckham Law, instead of paying Spanish progressive income tax on your worldwide income, you pay a flat 24% on Spanish-sourced income up to €600,000. Above that, the rate jumps to 47%, but for most expats the lower bracket is the relevant one. Crucially, you are not taxed on foreign income at all — you're treated like a non-resident for tax purposes, even though you physically live here.

That's a significant saving. Someone earning €120,000 in Spanish salary would pay around €40,000 under normal IRPF rates. Under the Beckham Law, the same person pays roughly €28,800. The gap widens further if they also have investment income or rental income abroad.

Who Qualifies for the Beckham Law?

To apply, you must:

Not have been a Spanish tax resident in the previous five years
Move to Spain because of a work contract (employment or, since 2023, as a digital nomad or entrepreneur under the Ley de Startups)
Apply within six months of registering with Spanish Social Security (or, for digital nomads, within six months of getting your visa)
Have work that is genuinely performed in Spain, or — for the newer digital nomad/entrepreneur category — be working remotely for foreign companies

The regime lasts for the year you arrive plus five subsequent years. After that, you fall into the standard IRPF system.

One thing that tripped up a lot of people before the 2022 Ley de Startups reforms: the Beckham Law was originally only available to employees transferred by foreign companies to Spain. Freelancers and the self-employed were excluded. The new rules opened it up to digital nomads, entrepreneurs, and certain highly qualified professionals — which is why there's now so much noise about it in remote-work circles. If you're on the Spanish Digital Nomad Visa, this is the tax regime you're being pointed towards.

How to Actually Apply

You apply using Modelo 149 — a form you submit to the Agencia Tributaria. You'll then file your annual return using Modelo 151 instead of the standard Modelo 100. The deadline for Modelo 149 is six months after your Social Security registration date. Miss it and you cannot apply retrospectively. This is not the place to procrastinate.

Getting a gestor or asesor fiscal (tax adviser) who knows this regime is worth every euro of their fee. The application isn't technically complex, but the eligibility conditions have enough nuance — particularly around the "not previously resident" requirement and the employment contract conditions — that DIY errors are common. If you're also registering as autónomo, you'll want expert help there too.

Modelo 720: The Asset Declaration Nobody Warns You About

If you're a Spanish tax resident with assets held abroad — bank accounts, investments, property, life insurance policies — and the total value exceeds €50,000 in any category, you must declare them using Modelo 720. You file once when you first become resident, and then again in any subsequent year where the value of any category increases by more than €20,000.

Historically, the penalties for not filing Modelo 720 were eye-watering (up to 150% of the undeclared asset value), and the European Court of Justice ruled in 2022 that Spain's enforcement was disproportionate. Spain has since amended the penalties downward, but the obligation to file still stands, and failure to do so is still a serious matter. If you have a UK pension pot, ISAs, a property back home, or a share portfolio, get advice before your first filing season.

When You Stop Being Tax Resident

Leaving Spain doesn't automatically end your tax residency. If you deregister (baja consular, if you're an EU citizen, or simply leave and can demonstrate it), and you spend fewer than 183 days in Spain in the new year, you're no longer resident. But Spain has an exit tax — if you leave with unrealised capital gains on shares or investments above certain thresholds (broadly, assets worth more than €4 million, or gains over €1 million), those gains are treated as crystallised at the point of departure. This doesn't affect most people, but it's worth knowing if you've built up a significant portfolio.

Also worth noting: you need to file a final tax return for the year you leave, covering the period you were resident. People forget this, get a letter two years later, and then face late-payment surcharges on top.

Practical First Steps When You Arrive

Before any of the tax stuff kicks in properly, you need a NIE number — the Número de Identidad de Extranjero — which is your tax identification number in Spain. Without it, you can't file a tax return, open a bank account, or sign a rental contract. Getting one can take longer than you'd expect; the wait times at NIE appointments have been significant in 2025–2026. Once you have your NIE, opening a bank account is the next step — non-residents can do this, though the process has quirks worth understanding before you walk into a branch (more on that here).

You'll also want to get on the padrón — the municipal register — as it's required for a TIE card, some tax filings, and access to local services. If your rental situation is complicated, there are ways to register without a standard rental contract.

A Word on the Double-Taxation Treaty with the UK

The UK-Spain Double Taxation Convention is the document that determines which country taxes what income for people who have connections to both. In broad terms: UK state pensions are taxed in Spain once you're resident here. Private pensions can be more complicated depending on their source. UK rental income is taxable in the UK first, then declared in Spain (with credit for UK tax paid). UK dividends and interest follow a similar logic.

The treaty is not a get-out-of-jail card — it doesn't mean you pay zero tax somewhere. It means you don't pay the full rate in both countries simultaneously. If Spain's rate is higher than the UK's on a given income type, you'll top up the difference in Spain.

For Americans, the situation is more complicated because the US taxes citizens on worldwide income regardless of where they live. American expats in Spain essentially have to file in both countries every year, and the US-Spain tax treaty has gaps. This is firmly a job for a specialist dual-jurisdiction tax adviser.

The Spanish tax system is genuinely manageable once you understand the structure, but the interaction between residency rules, the Beckham Law, Modelo 720, and bilateral treaties means that the first year especially rewards getting proper advice early. A good asesor fiscal who works with expats will typically charge €200–€500 for an annual return, more if you have complex foreign assets. Given what's at stake, that's rarely money wasted.
