Once you're a Spanish tax resident, your UK state pension and most private/workplace pensions are taxable in Spain, not the UK — Spain taxes your worldwide income, and the UK–Spain double tax treaty gives Spain the taxing rights on these. The main exception is a UK government-service pension (civil service, NHS, armed forces, police, teachers, local authority), which generally stays taxable in the UK — though it's still factored into your Spanish position. To stop the UK taxing pensions Spain should tax, you file an HMRC form to receive them gross. The UK 25% tax-free lump sum is not recognised as tax-free in Spain, which is a major planning point — taking it after becoming Spanish resident can mean Spanish tax on it. Pensions are taxed in Spain as general income on the progressive scale, and declared on your annual Renta return.
The Basic Principle
Everything flows from one fact: Spain taxes its tax residents on worldwide income. The moment you become a Spanish tax resident — broadly, by spending more than 183 days a year in Spain or having your main interests here — your income from everywhere, including UK pensions, comes into the Spanish net. That's the opposite of how many British retirees instinctively think; they imagine the UK keeps taxing "their UK pension," when in fact residence shifts most of it to Spain.
Where the same income could be taxed by both countries, the UK–Spain double taxation treaty steps in and allocates the taxing right to one country, so you're not taxed twice. For pensions, the treaty draws a clean line: ordinary pensions (state pension, private and most workplace pensions) are taxable in your country of residence — Spain — while government-service pensions are generally taxable in the country that paid them — the UK. Understanding which side of that line each of your pensions falls is the whole game, because it determines who taxes it and what you need to do to avoid double taxation.
Residence changes everything
UK pensions don't automatically stay UK-taxed just because they're British. Becoming Spanish tax resident shifts most pension income to Spanish taxation under the treaty. The practical steps — telling HMRC, claiming gross payment, declaring in Spain — follow from that shift, so getting your residence position right is the foundation.
How Each Pension Is Treated
It helps to take the main UK pension types one by one, because they don't all behave the same way:
| UK pension | Taxed where (if Spanish resident) | Notes |
|---|---|---|
| State pension | Spain | Paid gross by the UK; declared and taxed in Spain as income. |
| Private / personal pension | Spain | SIPPs, personal pensions — taxable in Spain; arrange gross payment from the UK. |
| Workplace / occupational (private sector) | Spain | Company schemes — taxable in Spain under the treaty. |
| Government-service pension | UK (generally) | Civil service, NHS, armed forces, police, teachers, local authority — stays UK-taxed; still factored into Spanish position. |
| Annuities | Spain (often favourably) | Purchased annuities can be taxed on a favourable basis in Spain depending on age — worth checking. |
So for a typical British retiree with a state pension and a private or workplace pension, the answer is usually "Spain taxes it all." The complication arises when there's a government-service pension in the mix — common for retired teachers, nurses, civil servants, forces and police — because that part is treated differently, and that's the most frequent source of confusion. The annuity point is a useful and often-overlooked positive: certain purchased annuities can be taxed in Spain on only a portion of each payment depending on the age at which the annuity began, which can make annuity income surprisingly tax-efficient here.
Government-Service Pensions
This is the exception that trips people up. Under the treaty, pensions paid for services rendered to the UK government — including the civil service, NHS, armed forces, police, fire service, teachers and local-authority schemes — generally remain taxable in the UK, not Spain, even after you become Spanish resident. So a retired teacher's teacher's-pension typically stays within UK tax, taxed under PAYE as it always was.
But there are two important wrinkles. First, this only covers the government-service pension itself; any state pension or private pension the same person holds is still taxable in Spain. Many public-sector retirees therefore end up with a split position — part UK-taxed, part Spain-taxed — and need to handle both correctly. Second, even though Spain doesn't tax the government-service pension, it may still be taken into account when working out the rate of Spanish tax on your other income (an "exemption with progression" effect), so it can't simply be ignored on the Spanish side. And if you later acquire Spanish nationality, the treatment of a government pension can change. Getting this right for public-sector retirees is one of the more valuable things proper advice does.
The 25% Lump Sum Trap
This is the single most expensive misunderstanding for British retirees, so it deserves its own section. In the UK, you can usually take 25% of a pension pot as a tax-free lump sum (the "pension commencement lump sum"). It's a cornerstone of UK retirement planning. The problem: Spain does not recognise that lump sum as tax-free. If you take it while you are a Spanish tax resident, Spain can tax it — potentially as a large slug of income in a single year, pushing you into high tax bands.
The timing therefore matters enormously. Someone who takes their tax-free lump sum before becoming Spanish tax resident, while still UK-resident, gets it tax-free under UK rules. Someone who waits until after they've moved and become Spanish resident can find a chunk of it taxed in Spain. There can also be limited transitional relief on certain older pension contributions, but it's narrow and not something to bank on. The practical lesson is simple and important: if you're planning to take a UK tax-free lump sum, get advice on the timing relative to your move — doing it in the wrong order can cost many thousands of euros. We flag this for every client with a UK pension pot they haven't yet drawn.
Take advice before you draw down
The UK's 25% tax-free lump sum is not tax-free in Spain. Taking it after you become Spanish resident can trigger Spanish tax on the whole amount in one year. If a lump sum is part of your plan, the timing relative to your residence change is one of the most valuable decisions to get right.
Getting Paid Gross by HMRC
When you become Spanish resident and your pensions become Spanish-taxable, you don't want the UK also deducting tax at source — that creates the very double taxation the treaty is meant to prevent, leaving you to reclaim it later. The fix is a formal process:
Register as Spanish tax resident
Become tax resident and start filing in Spain, so you have a basis to claim treaty relief.
Obtain a Spanish residence/tax certificate
The Spanish tax authority issues confirmation of your tax residence, which HMRC needs.
File the HMRC double-taxation claim
Submit the relevant HMRC form (the "DT-Individual" / Spain double-taxation form), certified by the Spanish authorities, asking HMRC to pay treaty-covered pensions gross.
Receive pensions gross & declare in Spain
HMRC adjusts your UK code so the relevant pensions are paid without UK tax, and you declare and pay on them through your Spanish return.
Done properly, this means each pension is taxed once, in the right country. Government-service pensions are excluded from the gross-payment claim because they're meant to stay UK-taxed. The process takes some time and coordination between the two tax authorities, which is exactly the kind of cross-border admin we handle for clients so it doesn't drag on or go wrong.
How Spain Taxes Pension Income
Once your pensions are in the Spanish system, they're taxed as general income (rendimientos del trabajo) on the progressive income-tax scale — the same scale that applies to employment income — combining state, regional and any applicable elements. The more pension income you have, the higher the marginal rate on the top slice, with personal and age-related allowances reducing the taxable amount. For most retirees the effective rate is moderate, but those with substantial pension income should expect Spanish rates that can exceed what they paid in the UK on the same money, particularly once multiple pensions stack up.
This is declared each year on the Declaración de la Renta (Modelo 100). Pension income from abroad must be converted to euros and reported, and where a government-service pension is UK-taxed, it's handled through the exemption-with-progression mechanism rather than simply left off. Because pension income is usually the backbone of a retiree's finances, getting the Renta right — claiming the correct allowances, applying the treaty properly, and avoiding both under-declaration and over-payment — is central to making retirement in Spain work financially. It also interacts with Modelo 720 if your pension arrangements include reportable foreign assets.
Planning & Common Mistakes
The recurring errors we see with British retirees and their UK pensions:
- Assuming UK pensions stay UK-taxed. Most become Spanish-taxable on residence — the instinct that "it's a UK pension so the UK taxes it" is usually wrong.
- Taking the 25% lump sum after moving. The single costliest mistake — it's not tax-free in Spain, so timing it before residence (or getting advice) is crucial.
- Leaving UK tax deducted at source. Without the HMRC gross-payment claim, you're taxed twice and have to reclaim — slow and avoidable.
- Misclassifying a government pension. Public-sector retirees often have a split position; treating it all as Spanish-taxable (or all UK-taxed) is wrong.
- Forgetting exemption-with-progression. A UK-taxed government pension can still raise the Spanish rate on other income — it's not simply ignored.
- Not declaring foreign pensions in Spain. Worldwide income must be reported; quietly leaving a UK pension off the Renta is a compliance risk.
The throughline is that UK pension taxation in Spain is very manageable — but only if it's set up correctly from the move, in the right order, with the treaty claims filed and the lump-sum timing considered. That's the difference between a smooth, tax-efficient retirement and an expensive muddle.
How We Help
We help British retirees get their UK pensions taxed correctly — once, in the right country. We confirm your residence position, identify which pensions are Spanish-taxable and which (government-service) stay UK-taxed, and handle the treaty claims with HMRC so your pensions are paid gross rather than double-taxed. Critically, we advise on the timing of any tax-free lump sum before it's too late, prepare your annual Renta return with the pensions and allowances correctly applied, and coordinate with Modelo 720 where needed. It's all in plain English, on a clear quote. Book a consultation — ideally before you draw down or move, when planning is still possible.

Retiring from the UK →Frequently Asked Questions
If you're a Spanish tax resident, your UK state pension is taxable in Spain, not the UK. Spain taxes residents on worldwide income, and the UK–Spain treaty gives Spain the taxing right on the state pension. It's paid gross by the UK and you declare it on your Spanish Renta return as income, taxed on the progressive scale alongside your other pensions.
Private and private-sector workplace pensions (including SIPPs and personal pensions) are also taxable in Spain once you're resident, under the treaty. You should arrange for them to be paid gross from the UK via the HMRC double-taxation claim, then declare them in Spain. The exception is government-service pensions, which generally stay taxable in the UK.
Generally no — government-service pensions (civil service, NHS, armed forces, police, teachers, local authority) usually remain taxable in the UK under the treaty, even after you become Spanish resident. However, they can still be taken into account when calculating the Spanish tax rate on your other income (exemption with progression), and the position can change if you acquire Spanish nationality. Many public-sector retirees have a split position needing careful handling.
No — and this is the most expensive misunderstanding. Spain does not recognise the UK's 25% pension lump sum as tax-free. If you take it while Spanish tax resident, Spain can tax it, potentially as a large amount of income in a single year. Taking it before becoming Spanish resident (while UK-resident) keeps it tax-free under UK rules. If a lump sum is part of your plan, get advice on the timing before you draw it.
You file an HMRC double-taxation claim (the DT-Individual / Spain form), supported by a Spanish tax-residence certificate, asking HMRC to pay treaty-covered pensions gross. HMRC then adjusts your UK code so those pensions are paid without UK tax, and you declare and pay on them in Spain. Government-service pensions are excluded because they're meant to stay UK-taxed. The process takes coordination between both authorities.
Pensions are taxed as general income on Spain's progressive income-tax scale, with personal and age-related allowances reducing the taxable amount. The more pension income you have, the higher the marginal rate on the top slice. For most retirees the effective rate is moderate, but those with substantial or multiple pensions can pay more in Spain than they did in the UK on the same money. It's declared annually on the Renta.
Yes. As a Spanish resident you must report your worldwide income, including UK pensions, on your annual Renta return, converted to euros. Even a UK-taxed government pension is factored in (via exemption with progression) rather than simply left off. Failing to declare foreign pension income is a compliance risk, so it should be handled properly each year.
Ideally before you move or draw down your pension. The timing of a tax-free lump sum, the order of becoming resident, and setting up the HMRC gross-payment claims are all best handled in advance. Getting advice early can save thousands and avoid double taxation; getting it after the lump sum is taken or after a year of double deductions is damage limitation.
