Yes: if you've retired with no workplace pension and only the State Pension, you can claim overpaid PAYE during the tax year online or on form P50, while anyone getting a workplace pension gets the refund through their tax code instead.

Why retiring mid-year often means overpaid tax

Through PAYE, your employer works out tax as though your job will carry on all year, spreading your £12,570 Personal Allowance across your paydays. If you stop work in, say, September, you've only had part of that allowance, but you've paid tax on almost everything you earned. If your income for the rest of the year is low, the unused allowance means you've paid more tax than you owe for the year.

How much comes back depends on what you live on afterwards. A State Pension or a workplace pension uses up some or all of the unused allowance, so the refund can be small. Someone who retires early and has little other income can be owed hundreds of pounds.

Which way to claim depends on your income now

GOV.UK's "Check how to claim a tax refund" tool sends retired people down one of three routes:

You'll get a workplace pension before 5 April: you don't need to claim. The tool says you'll get any tax you're owed the next time your tax code is reviewed, usually at the end of the tax year, through your pension provider.
No workplace pension, no Self Assessment, and you won't work again this tax year: you can claim now, online or on paper form P50.
You must send a Self Assessment return: the refund is dealt with through your return.

Using P50 when your only income is the State Pension

People are often told, wrongly, that you can't claim because you're getting a pension. HMRC's P50 guidance says you can claim if you "have retired and do not get a pension from your old employer". It's a workplace or occupational pension that rules P50 out, because that provider can make the repayment instead.

The State Pension is different. The form asks you to declare it, alongside any other income since you stopped work, but it isn't one of the benefits that stops you using P50. Those are Jobseeker's Allowance, Employment and Support Allowance, Carer's Allowance and Incapacity Benefit (after 28 weeks). When the online questions ask about your situation, choose that you're not working and don't plan to work again before 5 April.

Before you claim, make sure you've had your final pay, and have your National Insurance number and parts 2 and 3 of your P45 to hand. If you don't have the P45, the form asks you to explain why. You also can't use P50 if you've taken a flexible pension payment (that's form P55) or a small pension lump sum (P53 or P53Z).

What happens after you claim

HMRC will confirm the refund, ask for more information, or explain why you're not due one. GOV.UK asks you to wait at least 14 days before chasing. If you're owed money, HMRC sends a cheque (a "payable order") to you or someone you nominate, within 5 weeks of processing. It can't pay by bank transfer for P50 claims. Chase after 5 weeks for an online claim or 6 weeks for a postal claim.

If you'd rather wait until after 5 April

After the tax year ends, HMRC gets income details from employers, pension providers and DWP and checks your tax. If you've been overpaid, it sends a P800 tax calculation, usually between June and March. If the State Pension is your only income, you usually won't pay tax on it if it's within your Personal Allowance. If you do go over, HMRC sends a Simple Assessment bill instead.

Common mistakes

Claiming before your final payslip. Holiday pay or a final bonus can change the figures.
Forgetting the State Pension. It's taxable income, even though it's paid without tax deducted, and HMRC will count it.
Leaving it too long. GOV.UK's tool currently goes back to 6 April 2022. You can't reclaim tax overpaid before then.

Linda's 2026/27 refund after retiring in September

Worked example

Retiring early, no pension yet: Linda, 63, earns £3,000 a month and retires at the end of September 2026. She earned £18,000 in the tax year, and her P45 shows £2,343 of tax deducted.

Tax she actually owes for 2026/27: (£18,000 − £12,570) × 20% = £5,430 × 20% = £1,086.
Refund due: £2,343 − £1,086 = £1,257. She has no workplace pension and won't work again this tax year, so she can claim now on P50.

Same job, but she starts the full new State Pension in October: 26 weeks at £241.30 = £6,273.80.

Total income: £18,000 + £6,273.80 = £24,273.80. Tax owed: (£24,273.80 − £12,570) × 20% = £11,703.80 × 20% = £2,340.76.
Refund due: £2,343 − £2,340.76 = just £2.24. The State Pension has used up almost all the allowance she hadn't had through PAYE.

Your own refund depends on your pay, any pension income and when you stopped. Use your P45 for the tax already paid, and our take-home pay calculator for the annual figure.

How do I claim a tax refund after retiring?#

If you won't get a workplace pension before 5 April and don't do Self Assessment, you can claim online or on form P50 once you've had your final pay. If you will get a workplace pension, any refund comes through your pension's tax code, usually at the end of the tax year. Self Assessment filers claim on their return.

Can I use form P50 if I get the State Pension?#

Yes. HMRC's P50 guidance covers people who have retired and don't get a pension from their old employer, and the form simply asks you to declare your State Pension. A workplace pension, or benefits like Jobseeker's Allowance, ESA or Carer's Allowance, are what send you down a different route.

Will HMRC refund overpaid tax automatically when I retire?#

Sometimes. If you get a workplace pension, the refund comes through your tax code. Otherwise HMRC checks your tax after 5 April and may send a P800 between June and March. Claiming on P50 means you can get the money during the tax year instead of waiting.

How long does a P50 tax refund take?#

GOV.UK asks you to wait at least 14 days before contacting HMRC about your application. If you're owed money, HMRC sends a cheque within 5 weeks of processing the claim. Chase it after 5 weeks for an online claim or 6 weeks for a postal one.

Why did I pay too much tax in the year I retired?#

PAYE works out tax as though your pay will continue all year, so by the time you stop you've only had part of your £12,570 Personal Allowance. If your income for the rest of the year doesn't use up the remainder, you've overpaid. A State Pension or workplace pension often uses most of it, which is why some retirees get very little back.

What if I start a workplace pension after I retire?#

Then you don't claim on P50. GOV.UK says you'll get any tax you're owed the next time your tax code is reviewed, usually at the end of the tax year, and your pension provider makes the repayment. If you think your code is wrong in the meantime, update your details with HMRC.

Can I claim a refund for a previous tax year after retiring?#

Yes, for the last four tax years. GOV.UK's refund tool currently covers tax paid from 6 April 2022, and you can't reclaim anything overpaid before that date. If you left work and got your last pay before the current tax year began, use GOV.UK's route for previous tax years instead of P50.
