The first tax return — Girona

You thought leaving the UK meant leaving HMRC. You did not.

Spanish tax residency kicks in the moment you spend more than 183 days in Spain in a calendar year — and from that point, Spain taxes your worldwide income. Not just your Spanish income. Everything. Your UK pension, your rental income from the flat in Bristol, your ISA interest, your freelance invoices. All of it lands on a Spanish tax return, and HMRC does not simply wave you off at the border either.

Girona has specific characteristics that make this more complicated than the generic Spain relocation guides suggest. You are in Catalonia, which means regional tax rates apply on top of national ones. You are likely arriving as a post-Brexit UK national, which means no EU freedom of movement and a visa category that directly shapes your tax treatment. This article is for anyone who has become, or is about to become, a Spanish tax resident while living in Girona — and who wants to understand what they are actually walking into before the first April deadline arrives.

What the first tax return actually looks like in Girona

How Spanish tax residency is triggered and what it means for Girona residents

The 183-day rule is the primary trigger, but it is not the only one. If your main economic interests are in Spain — your business, your primary income source, your family home — you can be deemed tax resident even if you have spent fewer days here. For most people relocating to Girona, the 183-day threshold is the one that matters, and it resets on 1 January each year.

Once you are tax resident, you file the Declaración de la Renta — Spain's annual income tax return — covering the previous calendar year. The filing window runs from April to June. Your first return will likely cover a partial year, depending on when you arrived, but partial-year residency does not mean partial-year complexity. You still need to declare all income from the date residency began.

Catalonia operates its own regional income tax band on top of the national rate, which means Girona residents pay a combined national and Catalan rate. This is not dramatically different from other Spanish regions, but it is worth knowing that the Catalan regional government sets its own thresholds and deductions, and a tax advisor unfamiliar with Catalan specifics may miss reliefs that apply to you (Source: Agència Tributària de Catalunya).

What the Agència Tributària de Catalunya adds to the picture

The Agència Tributària de Catalunya handles the regional component of your tax affairs separately from the national Agencia Tributaria. In practice, most residents file a single combined return through the national system, but the Catalan regional deductions — for things like renting a primary residence, certain family circumstances, and cultural donations — are administered regionally and require a tax advisor who knows where to look.

If you are renting in Girona's historic centre or Eixample rather than owning, there is a Catalan regional deduction for rental costs on a primary residence that many newly arrived UK nationals miss entirely in their first year. It is not enormous, but it is real money left on the table if your advisor is not across Catalan-specific reliefs (Source: Agència Tributària de Catalunya).

The national return is filed online via the Agencia Tributaria's Renta WEB system. It is available in Spanish and Catalan. It is not available in English. Budget time and professional help accordingly.

What surprises people

The UK-Spain double taxation treaty does not eliminate your UK obligations

The UK-Spain Double Taxation Convention exists to prevent you being taxed twice on the same income — but it does not mean you stop filing in the UK. If you have UK-source income, HMRC still wants to know about it. The treaty determines which country has primary taxing rights over each income type, and you claim relief in the other country accordingly. What it does not do is make your UK tax affairs disappear the moment you register as resident in Girona.

UK rental income, for example, is typically taxed first in the UK under the treaty, with Spain then taxing it but crediting the UK tax already paid. This sounds clean in theory. In practice, it means running two parallel tax processes — one with HMRC, one with the Agencia Tributaria — and ensuring the figures reconcile correctly between them (Source: HMRC).

Girona's expat community creates a false sense of security around informal advice

Girona has an estimated 5,000–10,000 expat residents (Source: RelocateIQ research), and the community is genuinely helpful for settling in. It is less helpful for tax advice. The tapas bar consensus on what you do and do not need to declare is not a reliable guide to Spanish tax law, and the consequences of getting it wrong — penalties, interest, and in serious cases, criminal liability — are not proportionate to the convenience of skipping professional advice.

The specific risk in Girona is that a significant portion of the expat community arrived before Brexit, under EU freedom of movement rules, and their tax situation differs from yours as a post-Brexit UK national. What applied to them may not apply to you.

The numbers

Key cost of living figures relevant to financial planning in Girona

The cost savings are real and they compound quickly — lower rent, lower food costs, and lower private healthcare costs in the transition period all reduce the income you need to sustain the same quality of life. What the table cannot show is the tax drag that arrives alongside residency. Spain's combined national and Catalan income tax rates are progressive and reach levels that surprise people accustomed to thinking of southern Europe as a low-tax environment. The cost of living advantage is genuine; the assumption that tax will also be lower requires more careful examination, particularly for higher earners or those with significant UK-source income running alongside Spanish residency.

What people get wrong

Assuming the Beckham Law is available to everyone who arrives in Girona for work

The Beckham Law — formally the Special Expatriate Tax Regime — allows qualifying individuals to pay a flat 24% rate on Spanish-source income for up to six years, rather than the progressive combined national and Catalan rates. It sounds straightforwardly attractive. The eligibility conditions are specific: you must not have been Spanish tax resident in the previous five years, you must be employed by a Spanish company or seconded to Spain, or qualify under the Digital Nomad Visa route, and you must apply within six months of starting work (Source: Agencia Tributaria). Many people arriving in Girona on a Digital Nomad Visa assume they automatically qualify. They do not — the application must be made actively, and missing the six-month window means losing the regime entirely for that period of residency.

Treating the Modelo 720 as optional

The Modelo 720 is a declaration of overseas assets — bank accounts, property, investments — held outside Spain with a combined value above €50,000 per category (Source: Agencia Tributaria). If you have a UK property, a UK pension pot, UK investment accounts, or significant savings in a UK bank, you almost certainly need to file it. The historical penalties for non-filing were severe enough to attract European Court of Justice scrutiny, and while the penalty regime has been reformed, the obligation to declare remains. UK nationals relocating to Girona with existing UK assets consistently underestimate how much of their financial life falls within scope.

Assuming your UK accountant can handle the Spanish side

Your UK accountant knows HMRC. They do not necessarily know the Agencia Tributaria, the Agència Tributària de Catalunya, or the interaction between the two systems under the UK-Spain treaty. These are different bodies, different filing systems, and different legal frameworks. Running your Spanish tax affairs through a UK accountant who is not qualified in Spanish tax law is a risk that tends to surface at the worst possible moment — usually when a Spanish tax inspection arrives. Girona has qualified gestors and asesorías fiscales who handle exactly this dual-jurisdiction situation for UK nationals; use one.

What to actually do

Get your residency and tax status sorted in the right order

The sequence matters more than people realise. Before you can file a Spanish tax return, you need a NIE (Número de Identificación de Extranjero) and, for longer-term residency, a TIE. The TIE registration process in Girona runs through the city's police immigration office and typically takes three to six months from application to card issuance (Source: Spanish Immigration Authority, 2026). Start this process before you arrive if possible, or immediately upon arrival — do not wait until you feel settled.

Once you have your NIE, open a Spanish bank account. CaixaBank and Sabadell both operate locally in Girona and are accustomed to handling accounts for newly arrived foreign residents. You will need a Spanish account to pay taxes, receive any Spanish income, and manage local direct debits. This is not optional infrastructure — it is the foundation everything else sits on.

Find a tax advisor in Girona who knows both systems

Girona has a small but functional professional services community for English-speaking expats, and finding a gestor or asesoría fiscal with genuine dual-jurisdiction experience — UK and Spanish — is achievable but requires asking the right questions. Services like Girona Relocation can point you toward vetted professionals. The expat community in the Barri Vell and Eixample areas is also a reasonable source of referrals, with the caveat noted earlier about pre-Brexit residents whose situation differs from yours.

Book an initial consultation before your first full tax year ends. Bring documentation of all your UK income sources, your UK property situation, your pension arrangements, and any investment accounts. The more complete the picture you give your advisor, the less expensive the surprises will be. The April-to-June filing window arrives faster than you expect, and scrambling for documents in May is an avoidable problem.

Register with CatSalut as soon as your TIE is issued — the one-month waiting period means you want to trigger it early, and private health insurance at €60–100 per month is a running cost worth eliminating as soon as you are eligible (Source: RelocateIQ research).

Frequently asked questions

When do I become a Spanish tax resident?

You become a Spanish tax resident if you spend more than 183 days in Spain during a calendar year, or if Spain is the centre of your main economic or vital interests — whichever applies first.

For Girona residents, the 183-day count begins from your first day in Spain in that calendar year, not from the date you register at the Girona immigration office. The two dates are often different, and the tax clock does not wait for the bureaucracy to catch up.

Practically, keep a record of your travel dates from the moment you arrive. If you are splitting time between Girona and the UK in your first year, the exact day count matters and HMRC may ask for it too.

What is the Beckham Law and do I qualify?

The Beckham Law is Spain's Special Expatriate Tax Regime, which taxes qualifying individuals at a flat 24% on Spanish-source income for up to six years, rather than the progressive rates that would otherwise apply.

To qualify from Girona, you must not have been Spanish tax resident in the five years before arrival, and you must be working under a Spanish employment contract, a secondment arrangement, or — since 2023 — as a Digital Nomad Visa holder with qualifying remote income (Source: Agencia Tributaria). The application must be submitted within six months of starting work or activating your visa.

If you are on a Non-Lucrative Visa or retired, the Beckham Law does not apply to you. Get advice on this before your six-month window closes — it cannot be backdated.

Do I still have to file a UK tax return if I live in Girona?

Yes, if you have UK-source income — rental income, a pension, dividends from UK investments, or self-employment income from UK clients — HMRC still requires you to report it, even after you become Spanish tax resident.

The UK-Spain Double Taxation Convention determines which country taxes which income first, but it does not eliminate your UK filing obligation. Rental income from a UK property, for example, is typically taxed in the UK first, with Spain crediting that tax against its own charge (Source: HMRC).

You will also need to notify HMRC of your non-resident status by filing a P85 form if you were previously employed in the UK. This is a separate step from your Spanish tax registration and is worth doing promptly to avoid HMRC continuing to treat you as UK resident.

What is the Modelo 720 and who needs to file it?

The Modelo 720 is an annual declaration of overseas assets — bank accounts, property, securities, and insurance products — held outside Spain where any single category exceeds €50,000 in value (Source: Agencia Tributaria).

If you own a UK property, hold a UK pension, have UK investment accounts, or keep significant savings in a UK bank, you almost certainly fall within scope. The declaration is informational rather than a tax payment, but failure to file when required carries penalties.

File it by 31 March following the tax year in which you became resident. Your Girona-based tax advisor should include this as a standard part of your first-year setup — if they do not mention it, ask directly.

How much income tax will I pay in Spain?

Spain operates a progressive income tax system combining a national rate and a regional rate. As a Girona resident, your regional rate is set by the Catalan government, which applies its own bands and deductions on top of the national structure (Source: Agència Tributària de Catalunya).

The combined rate starts at around 19% on the lowest income band and rises progressively. Higher earners in Catalonia face combined marginal rates that can reach into the mid-forties on income above certain thresholds — this surprises people who assumed southern Europe meant lower taxes across the board.

The exact figure depends on your income level, income type, applicable deductions, and whether you qualify for the Beckham Law regime. A qualified asesoría fiscal in Girona can model your specific situation before you commit to residency.

How do I find a good English-speaking tax advisor in Girona?

Girona is a city of 105,000 people, not a major expat hub, so the pool of English-speaking tax professionals with dual UK-Spanish expertise is smaller than in Barcelona or Madrid — but it exists.

Start with Girona Relocation, which provides referrals to vetted local professionals and is familiar with the specific situation of UK nationals arriving post-Brexit. The expat community in Barri Vell and Eixample is also a practical source of recommendations, particularly from people who have already filed their first Spanish return.

When you speak to any advisor, ask specifically whether they have experience with the UK-Spain Double Taxation Convention and the Modelo 720. These are the two areas where a generalist Spanish gestor without international experience is most likely to leave gaps.

Can I be taxed in both the UK and Spain simultaneously?

In theory, no — the UK-Spain Double Taxation Convention is designed to prevent double taxation on the same income. In practice, you can find yourself filing in both countries and making payments to both tax authorities before the credits and reliefs are applied.

The treaty allocates taxing rights by income type. Employment income is generally taxed where the work is performed. Rental income from UK property is taxed in the UK first. Pensions depend on whether they are government or private. The mechanics of claiming relief in Spain for UK tax already paid require accurate documentation and a tax advisor who understands both systems (Source: HMRC).

The risk of effective double taxation is highest in your first year of Spanish residency, when timing differences between the two systems can create gaps. Getting professional advice before that first filing deadline is the most cost-effective thing you can do.

What are the tax implications of renting out my UK property while living in Girona?

UK rental income is taxable in the UK under the UK-Spain Double Taxation Convention, regardless of your Spanish residency status. You must register as a non-resident landlord with HMRC and file a UK self-assessment return declaring the rental income each year (Source: HMRC).

Spain will also include the UK rental income in your Spanish tax base, but will credit the UK tax already paid against the Spanish liability. This prevents double taxation but does not eliminate the administrative burden of running two parallel filings — one with HMRC, one with the Agencia Tributaria.

If your UK rental income pushes your total worldwide income into a higher Catalan tax band, the effective rate on that income in Spain may be higher than the UK rate alone. Your Girona-based tax advisor should model the full picture, not just the Spanish side in isolation.
