UK Pension in Spain: How Much Will You Pay in Tax?

By Sarah B. | Updated April 2026 | 8 min read

Retirement is one of the most common reasons British people move to Spain. But many retirees are surprised to find that their UK pension income is taxable in Spain – and that the rules differ significantly depending on what type of pension you have.

This guide covers the key rules around UK pension taxation in Spain. It is not a substitute for proper tax advice – pension taxation is genuinely complex and individual circumstances vary widely – but it gives you the framework to understand your situation.

The fundamental rule: Spanish tax residency

If you spend more than 183 days per year in Spain, you are a Spanish tax resident and are liable to pay Spanish income tax on your worldwide income. This includes your UK pension income, regardless of where it is paid or which bank account it goes into.

UK state pension in Spain

If you are a Spanish tax resident, your UK state pension is taxable in Spain only – not in the UK. The UK-Spain double taxation treaty reserves the right to tax state pension income for the country of residence. If you are living in Spain, Spain taxes it and the UK does not (though you may need to notify HMRC to stop any UK tax deductions).

The Spanish tax rates on pension income use the general progressive IRPF rates. For many retirees with a modest state pension as their primary income, the effective rate is low – Spain has a personal allowance and the lower rates (19 to 24%) apply to modest incomes.

UK government service pensions – the important exception

Government service pensions – paid to former civil servants, NHS employees, teachers, police officers, armed forces personnel and local government workers – are treated completely differently under the UK-Spain double taxation treaty. These pensions are taxable in the UK only, regardless of where you live.

This means that if you receive a NHS pension, a teacher’s pension or a civil service pension, you will continue to pay UK income tax on it after moving to Spain. Spain cannot tax it. However, you must still declare it on your Spanish tax return – Spain uses the information to determine whether your overall income takes you into higher tax brackets for other income sources.

This distinction catches many people out. If you have both a UK state pension (taxable in Spain) and a government service pension (taxable in the UK), you are dealing with two different tax regimes on two different income sources.

Private and workplace pensions

Private pensions – including former employer workplace pensions from private sector jobs, personal pensions and SIPPs – are generally taxable in Spain if you are a Spanish tax resident. The UK-Spain treaty does not reserve these for UK taxation in the way it does for government service pensions.

The effective rate depends on your total income in Spain. For many retirees whose only income is a private pension, the Spanish tax rate is manageable – Spain’s personal allowances and lower bands mean modest pension income is taxed at relatively low rates.

Pension lump sums

If you take a pension lump sum after becoming a Spanish tax resident, this can be significant. Spain taxes pension lump sums as income in the year of receipt, which can push you into higher tax brackets. Planning the timing of pension lump sum withdrawals around your Spanish tax residency start date is an area where specialist advice can save substantial sums.

The S1 certificate: reducing your healthcare costs

If you receive a UK state pension, you are entitled to an S1 certificate from the UK government. This certificate allows you to access Spanish public healthcare at Spain’s expense rather than the UK’s. It does not affect your tax position but it may eliminate or significantly reduce your private health insurance costs – one of the largest fixed expenses for NLV holders. Apply for your S1 certificate from the Department for Work and Pensions before you move.

Getting advice

For retirees with multiple pension types, UK property income, ISA investments and other UK financial assets, the tax position when moving to Spain requires proper professional advice. Specialist expat advisers like Chase Buchanan and Blevins Franks specialise in exactly this situation.
