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.

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 2026/27 — 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 as their first flexible payment. The tax-free element is £10,000 (25%), leaving £30,000 taxable. The provider applies code 1257L M1 (emergency Month 1 basis).

Under emergency tax (Month 1 basis), 2026/27:

• Monthly personal allowance: £1,047.50 tax-free
• Next £3,141.67 at 20% (monthly basic rate band, £37,700/12): £628.33
• Next £6,239.17 at 40% (monthly higher rate band, £74,870/12 — the band runs from £50,270 to £125,140 annualised): £2,495.67
• Remaining £19,571.66 at 45% (monthly income above £10,428.33 falls into the additional rate band): £8,807.25
• Total tax deducted: ~£11,931

Correct tax (assuming no other income), 2026/27:

• Personal allowance: £12,570 tax-free
• £30,000 − £12,570 = £17,430 taxed at 20%: £3,486
• Total tax due: £3,486

Overcharge: ~£8,445. 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: P55, P50Z, P53Z

HMRC provides three different forms for reclaiming overtaxed pension payments. Which one to use depends on how the pension was accessed and what other taxable income the individual receives. Submitting the wrong form will get the claim rejected or delayed, so the distinctions matter.

P55 — Partial withdrawal, pot NOT fully exhausted. 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.

P50Z — Pot FULLY withdrawn, no other taxable income. This applies when the entire pension has been taken as a lump sum AND the individual has no other taxable PAYE income (typically: stopped work, no other pension in payment, no State Pension yet, no employment).

P53Z — Pot FULLY withdrawn, WITH other taxable income. This applies when the entire pension has been taken as a lump sum AND the individual does receive other taxable income — for example, the State Pension, another pension already in payment, or employment income. P53Z is the form to use when there's something else going on tax-wise alongside the full encashment.

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. P800s are typically issued between June and the following March — meaning a withdrawal in April could take up to ~23 months to be fully reconciled in the worst case (April withdrawal → P800 issued by March of the following tax year).

For large overpayments — and £8,000–£12,000 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.
