If your pension provider has taken far more tax than you expected from a lump sum, it is almost certainly because the payment was run through an emergency tax code on a Month 1 basis — the payroll system treats your one-off withdrawal as if you will receive the same amount every month for the rest of the year. You can claim the overpayment back in-year using form P55, P53Z or P50Z, depending on whether you emptied the pot and whether you have other taxable income. If you do nothing, HMRC will reconcile it automatically after 5 April and send a P800 refund, but that can mean waiting months.
Key points
- Only the taxable part of a withdrawal is affected — the 25% tax-free element is never taxed.
- A Month 1 emergency code gives you just one-twelfth of the Personal Allowance (£1,047.50) and one-twelfth of each rate band, which is what pushes a modest lump sum into 40% or 45% tax.
- Use P55 if you took part of your pot, P53Z if you emptied it and still have other taxable income, and P50Z if you emptied it and have no other taxable income.
- Scottish taxpayers are over-taxed in the same way, but the refund is worked out using Scottish rates because pension income is non-savings income.
- Taking a small first payment, then the larger one once a proper tax code is in place, usually avoids the problem entirely.
Why Month 1 over-taxes your pension withdrawal
When you take a flexible payment from a defined contribution pension for the first time, your provider normally has no tax code for you from HMRC. It therefore uses the emergency code (1257L, or S1257L in Scotland) on a non-cumulative Month 1 basis. That means the payment is taxed as though it is the first of twelve identical monthly payments.
The practical effect is that you get one month's worth of everything:
| Slice of taxable pay in the month | Rate applied (England, Wales, NI) |
|---|---|
| First £1,047.50 (one-twelfth of the £12,570 Personal Allowance) | 0% |
| Next £3,141.67 (one-twelfth of the £37,700 basic-rate band) | 20% |
| Up to £9,380.83 of taxable pay | 40% |
| Above £9,380.83 of taxable pay | 45% |
So a taxable withdrawal of much more than about £4,200 in a single month starts attracting higher-rate tax, and anything above roughly £10,400 hits the additional rate — even if your total income for the whole year will only be £20,000.
Scotland
Pension income is non-savings income, so Scottish income tax rates apply if you are a Scottish taxpayer. The Month 1 split works the same way but uses the Scottish bands: 19% on the first £330.58 of taxable pay in the month, 20% up to £1,413.00, 21% up to £2,591.00, 42% up to £5,202.50, 45% up to £9,380.83 and 48% above that. Because the 42% rate starts much lower in cash terms, Scottish savers often see a bigger over-deduction on mid-sized lump sums.
Other codes you might see
Not every over-taxed withdrawal uses 1257L Month 1. If your provider holds a code from HMRC it may use BR (a flat 20%) or 0T (no allowance at all, with the bands still applied on a Month 1 basis). BR can under-tax a higher earner and 0T almost always over-taxes someone with allowance to spare. The reclaim route is the same.
Worked example: a £30,000 UFPLS
Priya, aged 58 and living in England, takes an uncrystallised funds pension lump sum of £30,000 and has no other income this tax year.
- 25% is tax free: £7,500. The taxable 75% is £22,500.
- Month 1 free pay: £22,500 − £1,047.50 = £21,452.50 of taxable pay.
- 20% on £3,141.67 = £628.33.
- 40% on £9,380.83 − £3,141.67 = £6,239.16, giving £2,495.67.
- 45% on £21,452.50 − £9,380.83 = £12,071.67, giving £5,432.25.
- Total deducted: £628.33 + £2,495.67 + £5,432.25 = £8,556.25. She receives £21,443.75.
Her actual liability for the year is far lower. Taxable income of £22,500 less the £12,570 Personal Allowance leaves £9,930, all in the basic-rate band: £9,930 × 20% = £1,986. She has overpaid £8,556.25 − £1,986 = £6,570.25. Because she has not emptied the pot and is not taking regular payments, she claims it back on a P55.
You can run your own numbers through the pension lump sum tax calculator to see the correct annual figure, and the emergency tax calculator to see what a Month 1 code will actually deduct.
Which form: P55, P53Z or P50Z
All three are in-year repayment claims for flexibly accessed pensions. Picking the right one matters — the wrong form will be rejected or delayed.
| Form | Use it when |
|---|---|
| P55 | You have taken only part of your pot, you are not taking regular pension payments, and your provider cannot refund the tax itself. |
| P53Z | You have taken all of your pot as a flexible payment and you still have other taxable income (wages, self-employment, rent, State Pension). |
| P50Z | You have taken all of your pot as a flexible payment and you have no other taxable income for the rest of the tax year. |
Two situations fall outside these forms. If you are in Self Assessment anyway, the overpayment is usually dealt with through your return rather than a separate claim. And if you take further taxable withdrawals later in the same tax year, your provider should operate the code HMRC issues after your claim, so a second reclaim is often unnecessary.
What you need to hand
- Your National Insurance number.
- The payslip or statement from the pension provider showing the gross payment and the tax deducted.
- Part 1A of a P45 if the provider issued one (common where the pot was emptied).
- An estimate of your total taxable income for the whole tax year, including the State Pension and any savings interest. HMRC uses this estimate to work out the refund, so a sloppy figure produces a wrong answer.
You can file the claim online through your Government Gateway account or print and post it. The online route is faster and gives you a submission record. Start from the GOV.UK P55 guidance or the general claim a tax refund pages, which link through to P53Z and P50Z.
How long a pension emergency tax refund takes
HMRC's published aim for these claims is to deal with them within about 30 days of receipt, with payment by bank transfer or cheque shortly after. Postal claims sit in a queue before they are even opened, so allow longer. Claims made close to 5 April are often simply rolled into the end-of-year reconciliation instead.
If you do nothing
The overpayment is not lost. After the tax year ends, HMRC compares the tax deducted through PAYE with what you actually owed and issues a P800 calculation, usually over the summer and autumn months following 5 April. You then claim the money online or wait for a cheque. That is fine if you are not short of cash; if the withdrawal was to pay for something specific, an in-year claim gets the money back far sooner.
One more thing to watch: HMRC may also issue a revised tax code for your employment or other pension based on the withdrawal, which can distort your monthly take-home. Check any new code against your real expected income.
How to avoid emergency tax on the next withdrawal
The over-deduction is a cashflow problem rather than a permanent loss, but it is largely avoidable.
- Take a token payment first. A small taxable withdrawal — say £100 — triggers the provider to report to HMRC, which then issues a proper cumulative code. Take the larger sum once that code is in place, usually the following month.
- Take only the tax-free cash. The 25% element carries no income tax at all, so drawing just that produces no deduction to reclaim. See the guide to the 25% tax-free pension lump sum for how it interacts with the rest of the pot.
- Spread taxable withdrawals across tax years. Two payments of £15,000 in different years, each against a full Personal Allowance, can cost far less than £30,000 in one go.
- Give your provider a P45. If you left a job in the same tax year, parts 2 and 3 let the provider use your real code rather than the emergency one.
- Keep an eye on the money purchase annual allowance. Taking taxable income flexibly cuts how much you can pay into pensions to £10,000 a year, down from the £60,000 annual allowance.
What to do next
Work out what the tax on your withdrawal should actually be with the pension lump sum tax calculator, then compare it with the deduction on your provider's statement using the emergency tax calculator. The difference is your claim. If the pot is still open and you are not taking regular payments, that is a P55; if you emptied it, it is P53Z or P50Z depending on whether you have other taxable income for the rest of the year.
