How UK pensions are taxed when you retire in Spain
If you become a Spanish tax resident your UK private and occupational pensions are generally taxable in Spain; the UK State Pension is usually taxable only in the UK under the double‑tax treaty. Here’s what to expect, the forms you’ll need and the concrete steps to avoid surprise bills.

If you are tax resident in Spain your UK private and occupational pensions are usually taxed in Spain; the UK–Spain treaty normally leaves the UK State Pension taxable only in the UK.
You still need to register in Spain (NIE, empadronamiento) and get a certificado de residencia fiscal from the Agencia Tributaria if you want treaty relief or credits.
Tell your UK pension providers before you move: who withholds tax and how they pay you changes if you become Spanish tax resident.
Do the simple admin yourself; hire an asesor/gestor for the first-year tax return and any one-off decisions (large lump sums, drawdown strategies, mid-year moves).
Short answer: if you become a Spanish tax resident, most UK private and workplace pensions will be taxed in Spain; the UK State Pension is normally taxable in the UK under the UK–Spain double tax treaty. The details — withholding, whether Spain gives credit for UK tax, whether a lump sum is treated differently — depend on the pension type and on timing, so you need paperwork and a plan.
1. Who counts as a Spanish tax resident — and why that matters
Spain taxes residents on worldwide income. You become tax resident if you spend more than 183 days in Spain in a calendar year or if your centre of economic interests is here. (The finer points are in our guide on tax residency: Tax residency: 183 days and the rest.)
If you’re resident, your UK pensions are part of your Spanish tax return (la declaración de la Renta). If you remain non‑resident, Spain taxes only Spanish-source income; your UK pensions will generally be left to the UK to tax (subject to the treaty).
2. Which UK pensions are taxed where
Don’t treat all “pensions” the same. The three common categories are:
UK State Pension — under the UK–Spain double tax treaty the UK usually has primary taxing rights. In practice that means the State Pension is normally taxable only in the UK.
Workplace and personal pensions (defined benefit, defined contribution, workplace schemes, SIPP drawdown etc.) — if you’re resident in Spain these are generally taxable in Spain. The treaty gives Spain the right to tax pensions paid in consideration of past employment.
One‑off lump sums (the UK 25% tax‑free lump sum on a DC pension) — the UK tax treatment is not the same as Spain’s. Spain may treat a lump sum as taxable income; do not assume the 25% tax‑free amount in the UK will be tax‑free in Spain.
Practical implication: expect to declare private/workplace pension payments on your Spanish return, even if the UK already taxes them. The treaty and domestic rules then decide whether Spain gives a credit, an exemption, or taxes the same income again.
3. How the double tax treaty works in practice
The UK–Spain treaty allocates taxing rights but it doesn’t automatically stop both countries asking for tax forms. Two routine steps people miss:
Get a certificado de residencia fiscal from the Agencia Tributaria once you’re a Spanish resident — you’ll need this if your UK pension payer asks for it to apply treaty rules. You can also use the certificate to claim a foreign tax credit in Spain for UK tax actually paid.
Tell UK pension schemes whether you are UK or Spanish resident. If they think you’re non‑resident they may stop deducting UK tax; if they think you’re resident in the UK they may keep deducting. Either way, document everything in writing.
The end result is usually one of two practical outcomes: either the UK taxes the income and Spain gives you a credit (so you don’t pay double tax), or Spain taxes the income and the UK gives no further claim. Which route applies depends on the type of pension — that’s why the paperwork matters.
4. Reporting and the paperwork you will need
If you live in Spain you file the annual Spanish income tax return (la declaración de la Renta / Modelo 100) for the previous calendar year; deadlines are published each year (normally April–June for the prior year). Your pension income, any UK tax paid and the certificate of tax residency all feed into that return.
Checklist: documents you should gather before filing
Passport and NIE (foreign ID number).
Empadronamiento certificate (municipal register) — proves days in Spain.
Pension statements: UK State Pension statement, annual statements from workplace and personal pension providers showing gross amounts and UK tax deducted.
Certificado de residencia fiscal from Agencia Tributaria (ask for it once you’re resident).
Bank details (IBAN) for payments and tax refunds.
Copies of any lump‑sum paperwork or enhanced commutation letters if you took a lump sum.
Get these before you sit down with software or an advisor. If your UK payer needs the certificado de residencia to stop withholding or to apply treaty rates, you’ll save weeks of delays if you already have it.
5. Practical steps to take before — and during — your first year
Do these in order. Missing one causes frictions later.
Decide whether you will be Spanish tax resident for the whole calendar year. If you move partway through the year, residency is a common source of surprises — get advice early.
Register locally: obtain your NIE, register on the padron (empadronamiento), and if you have a visa get your TIE (residence card). Our NIE guide explains the process: NIE number for retirees.
Contact each UK pension provider and tell them your anticipated tax residence date. Ask them whether they will deduct UK tax once you become non‑resident, and whether they need a Spanish residencia certificate to apply treaty rules.
Apply for the certificado de residencia fiscal at Agencia Tributaria as soon as you’re resident. This is the document most pension providers accept when applying treaty relief. (Agencia Tributaria: agenciatributaria.es.)
If you are a UK State Pension recipient look at S1 forms for healthcare, long before you need medical care: S1 form for UK pensioners and the Spanish social security pages: seg-social.es.
6. What you can do yourself — and when to pay an advisor
Do yourself: register for NIE, get empadronamiento, ask pension providers plain questions (“will you deduct UK tax if I move to Spain?”), and collect statements. You can probably fill a simple Spanish tax return online if you have straightforward income (State Pension only, small UK private pension with no lump sums).
Pay a gestor/asesor if any of these apply:
You move mid‑tax year and have income taxed in both countries.
You plan to take a large lump sum or do a pension transfer (QROPS/SIPP transfers have cross‑border implications).
You have multiple pensions, rental income, or capital gains that intersect with pension decisions.
You want to optimise the timing of drawdown or the use of tax credits — the rules are fiddly and a mistake can cost a lot.
Most people I know hired a local asesor for the first year and then switched to annual checkups. Expect to pay for a first‑year service that sorts out the certificate of residence, helps fill Modelo 100, and explains withholding — shop locally and ask for references from other expat retirees.
7. Common pitfalls and how to avoid them
Pitfall: assuming the UK 25% tax‑free lump sum stays tax‑free in Spain. Don’t assume. If you plan to take a lump sum, get written confirmation of UK tax treatment and take advice on Spanish treatment before you cash out.
Pitfall: not telling your UK provider you moved. They may keep deducting UK tax, or they may stop deducting it and expect you to account for it in Spain. Either way, you’ll want a paper trail.
Pitfall: timing a move mid‑year without planning. A move in March versus October can change which country claims taxing rights for a whole year, and that can change whether Spain taxes your entire pension for the year.
Pitfall: waiting to get the certificado de residencia. Some providers will not apply treaty relief without it; you could suffer unnecessary UK withholding until you produce it.
Fixes: get the certificate early, talk to providers, and get a one‑off consultation with an asesor on timing and lump sums.
Next action — what to do in the next 30 days
If you’re planning to move: 1) Apply for your NIE and register on the padron the week you arrive. 2) Contact every UK pension provider and ask two questions in writing: “If I become Spanish tax resident on [date], will you deduct UK tax from my payments?” and “Do you require a certificado de residencia fiscal from Spain?” 3) Apply for the certificado de residencia fiscal at Agencia Tributaria as soon as you’re resident. That three‑step sequence fixes 80% of the usual headaches.
FAQ
Will I pay tax in both Spain and the UK on my UK private pension?
Usually not. Private/occupational pensions are generally taxable in Spain if you’re Spanish tax resident. If tax has already been taken in the UK you can usually claim a credit in Spain or rely on treaty provisions. The exact mechanism depends on the pension type and whether the UK actually withheld tax. Get the certificado de residencia fiscal and save your UK payslips.
Is the UK State Pension taxed in Spain?
Under the UK–Spain double tax treaty the UK normally has the right to tax the State Pension. That means for most people the State Pension is taxed in the UK, not Spain. However you should still declare it on your Spanish paperwork and keep records — and check the latest treaty wording if your situation is complex.
Should I take my pension lump sum before I move?
Possibly, but don’t decide without advice. The UK’s 25% tax‑free lump sum may be treated differently by Spanish tax authorities. If the lump sum would be taxed in Spain, taking it before you become Spanish resident can sometimes be advantageous — but timing and numbers matter. Book an advisory session rather than guessing.
