UK pensions taxed up to 37%

A UK pension does not keep its old tax treatment just because you moved. That’s the whole point here. If you become tax resident in Spain, the tax story can flip — your UK State Pension can stop being taxed in the UK and start being taxed in Spain instead. HMRC’s own Spain treaty notes make that explicit, and Spain’s income tax system is progressive and region-sensitive, so the bill can end up noticeably higher for some retirees. (assets.publishing.service.gov.uk) ### Which pension is this about? The cleanest case is the UK State Pension. HMRC’s DT-Spain individual notes say a person resident in Spain can apply for exemption from UK income tax on a UK State Pension under the UK-Spain tax convention, using the treaty form and Spanish proof of residence. So the pension is still taxable income — but the taxing right usually moves to Spain. (assets.publishing.service.gov.uk) ### Why does Spain get to tax it? Because tax treaties usually follow residence for ordinary private pensions. The current UK-Spain convention entered into force in 2014, then became effective for UK income tax from April 6, 2015, and for Spanish income taxes from January (assets.publishing.service.gov.uk)mes the place where that pension is taxed. (gov.uk) ### Does that mean double tax? Basically, no — at least not if the paperwork is done properly. The treaty is meant to stop the same pension being fully taxed twice. HMRC says the Spanish resident can claim relief from UK tax, and GOV.UK’s State Pension guidance says if a double taxation agreement applies, you usually pay tax only once, in whichever c(gov.uk)still being withheld, you may need to claim relief or repayment. (assets.publishing.service.gov.uk) ### So where does the “up to 37%” idea come from? From Spain’s own income tax structure. Spain taxes residents on worldwide income through IRPF, a progressive system split between national and regional rates. That means your marginal rate depends on total taxable income an(assets.publishing.service.gov.uk)sh marginal rate for some retirees — but it is not a flat tax on every pound of pension. (sede.agenciatributaria.gob.es) ### Why can the bill feel worse than in the UK? Because the comparison people make is often between a UK retiree’s familiar effective rate and Spain’s higher marginal bands. In the UK, pensioners still use the normal income tax system, and many retirees stay near the personal allowance and basic rate. In Spain, once you are resid(sede.agenciatributaria.gob.es)nces, different brackets, and regional variation can all push the final bill up. (gov.uk) ### Are all UK pensions treated the same way? No — and this is where people get tripped up. HMRC’s internal manual says UK government or local-authority pensions get full relief in Spain only if the recipient is both a Spanish resident and a Spanish national. That means civil service and similar public-service pensions can follow di(gov.uk)sion” — hides several tax treatments. (gov.uk) ### What actually matters most? Residency. Not nationality. Not where the pension was earned. If Spain treats you as tax resident — usually because you live there long enough or your center of life is there — Spain can tax your worldwide income, including UK pensions. That is the real takeaway. The pension did not change. Your tax residence did. (assets.publishing.service.gov.uk) ### Bottom line The viral claim is directionally right but easy to oversimplify. A UK retiree in Spain can absolutely face a higher tax bill on pension income, and HMRC’s own treaty paperwork shows why. But the number depends on the pension type, your total income, your Spanish region, and whether the treaty relief has actually been set up. (assets.publishing.service.gov.uk)
