Emergency tax on pension withdrawals — how to reclaim it.
The first taxable withdrawal from a pension is almost always overtaxed. HMRC applies emergency tax because the provider doesn't yet have a tax code. The money is reclaimable — but only if you know the process.
- ▸Emergency tax is applied to the first taxable pension withdrawal because the provider typically doesn't hold a tax code from HMRC.
- ▸On a Month 1 basis, HMRC treats the single payment as if it will be received every month — a £30,000 taxable withdrawal is taxed as though annual income is £360,000.
- ▸The overtaxed amount can be reclaimed in-year using forms P50Z, P53Z, or P55 — or it will be corrected automatically after the end of the tax year, which can take up to 16 months.
Why HMRC applies emergency tax on first payments
When a pension provider makes a taxable payment — whether through drawdown, a UFPLS, or a full encashment — it must deduct income tax under PAYE before paying out. To do this correctly, it needs a tax code from HMRC that reflects the individual's personal allowance and other income.
For the very first payment from a pension, the provider usually doesn't have this tax code. HMRC hasn't issued one yet because the pension scheme has never made a payment to that individual before. Without a code, the provider falls back to the emergency tax basis.
Emergency tax operates on a Month 1 (non-cumulative) basis. This means:
- The provider treats the payment as if it's one twelfth of the annual income
- It applies a monthly personal allowance (£1,047.50 in 2025/26 — one twelfth of £12,570)
- It assumes the same amount will be paid in every remaining month of the tax year
- It applies the standard income tax bands accordingly
The problem is obvious. A one-off pension withdrawal of £30,000 isn't monthly income of £30,000. But emergency tax treats it as though annual income is £360,000 — pushing large chunks into the 40% and 45% bands.
How much extra tax you might pay
The overcharge depends on the size of the withdrawal and when in the tax year it happens. A worked example illustrates the scale.
Suppose someone takes a £40,000 UFPLS in May (month 2 of the tax year). The tax-free element is £10,000 (25%), leaving £30,000 taxable.
Under emergency tax (Month 1 basis):
- Monthly personal allowance applied: £1,047.50 tax-free
- Next £3,141.25 taxed at 20% (monthly basic rate band): £628.25
- Remaining £25,811.25 taxed at 40%: £10,324.50
- Total tax deducted: £10,952.75
Correct tax (assuming no other income):
- Personal allowance: £12,570 tax-free
- £30,000 − £12,570 = £17,430 taxed at 20%: £3,486
- Total tax due: £3,486
Overcharge: £7,466.75. That's money sitting with HMRC rather than in the retiree's bank account — reclaimable, but only through action.
The pension lump sum tax calculator estimates both the emergency tax deduction and the correct tax position for any withdrawal amount.
The three forms: P50Z, P53Z, P55
HMRC provides three different forms for reclaiming overtaxed pension payments. Which one to use depends on how the pension was accessed.
P55 — Flexible payment, pension not fully withdrawn. This is the most common form. It applies when a taxable flexible payment has been received (drawdown withdrawal or UFPLS) and the pension pot has not been fully encashed. The individual intends to take further payments in the future or leave the remainder invested.
P53Z — Pension fully withdrawn, no other PAYE income. This applies when the entire pension has been taken as a lump sum and the individual doesn't receive any other PAYE income (employment income or other pension income). If there is other PAYE income, HMRC adjusts the tax code on that income instead.
P50Z — Part of the pension taken, no further payments expected. This is less common. It applies when a partial withdrawal has been made and no further payments from that pension are expected in the current tax year.
All three forms are available on gov.uk and can be submitted online or by post. The process requires:
- The form itself (completed and signed)
- Parts 2 and 3 of the P45 from the pension provider (received after the payment)
Timing: in-year vs end of year reclaim
There are two ways the overcharge gets corrected:
In-year reclaim (faster). Submit the appropriate form (P50Z, P53Z, or P55) to HMRC as soon as the P45 arrives from the pension provider. HMRC typically processes refunds within 30 days of receiving the form. The refund is paid directly by cheque or bank transfer.
End of year reconciliation (slower). If no form is submitted, HMRC will eventually reconcile PAYE records after the end of the tax year (5 April). A P800 tax calculation will be issued, showing the overpayment, and a refund will follow. This process can take until July or August of the following tax year — meaning a withdrawal in April could take up to 16 months to be corrected.
For large overpayments — and £5,000–£10,000 is not unusual on a substantial first withdrawal — the in-year route is clearly preferable. There is no interest paid on the overpayment during the time HMRC holds it.
Subsequent payments from the same pension provider are usually taxed correctly, because HMRC will have issued a proper tax code after the first payment. Emergency tax is almost exclusively a first-payment problem.
