Will you get a refund on tax paid on a Civil Service pension?
You may, if you have paid too much. Civil Service pensions are taxable income and are taxed through PAYE using a tax code. If the code is wrong, for example because your Personal Allowance was split wrongly between a pension and a job, or an old code was used, you can overpay. HMRC normally sorts this out after the tax year ends and sends a P800 refund, but you can also claim yourself.
Why pensioners overpay tax
- Two pensions or a pension plus a job: the whole £12,570 Personal Allowance may be given to one source, and the other is taxed on a BR or D0 code
- State Pension: the State Pension is paid without tax deducted, so HMRC collects it through your Civil Service pension code. Errors here are common
- Emergency codes when the pension first starts
- Stopping work partway through the year
- Unclaimed Marriage Allowance, worth up to £252 a year
- Taxable benefits that ended, such as a company car, still showing in your code
How to check
- Compare the code on your pension payslip or P60 with the coding notice from HMRC
2. Check your personal tax account on gov.uk or in the HMRC app
3. Add up your total taxable income for the year, including the State Pension
4. Work out the tax you should have paid: 20% between £12,570 and £50,270 in 2026/27
Example
Jean receives a State Pension of £12,548 (the full new State Pension of £241.30 a week in 2026/27) and a Civil Service pension of £10,000. Her total income is £22,548, so she should pay 20% of £9,978, which is £1,995.60. Her code should therefore give her only £22 of allowance against the Civil Service pension. If her pension payslips show more than £1,995.60 deducted over the year, she has overpaid, and HMRC’s year-end reconciliation should refund the difference.
How to claim the refund
- P800: if HMRC sends one, follow its instructions. Many refunds are paid automatically
- Online: use your personal tax account to request the refund
- Self Assessment: if you file a return, the refund comes through the return
- Previous years: you can claim for the last 4 tax years, so claim 2022/23 by 5 April 2027
Civil Service lump sums
A tax-free lump sum taken at retirement isn’t taxable, so there is no tax to reclaim on it. If you take a taxable pension commencement lump sum above your limits, or a small pot lump sum, tax may be deducted at emergency rates. You can reclaim it with forms P53Z or P55.

Keep your P60s and coding notices.
