Emergency tax on pension withdrawals — and how to claim it back

The first flexible payment from a pension almost never arrives with the right tax taken off. The scheme deducts under the 1257L emergency code on a month-1 basis, which taxes a one-off payment as though it were one month of an annual income twelve times its size. On a £30,000 first withdrawal with no other income, £11,878.20 leaves at source against a true annual liability of £3,486 — an over-deduction of £8,392.20 that belongs to the member and has to be claimed back or waited for. None of it is lost; all of it is timing.

Why the scheme must over-tax the first payment

The taxable 75% of a withdrawal is pension income under ITEPA 2003 s.579A, and the scheme collects the tax through PAYE like an employer paying salary (PTM063300). But on a first flexible payment the scheme usually holds no current tax code for that income — there is no P45 for a pension pot. HMRC’s PAYE manual instructs the administrator to operate the emergency code, 1257L, on a week-1/month-1, non-cumulative basis (PAYE94055). This is not provider discretion or error: it is the prescribed treatment, and it applies however obviously one-off the payment is.

The month-1 mechanic, walked to the penny

Month-1 uses the first line of HMRC’s tables, but their rounding order matters. For 2026/27, Table A derives £1,048.26 of free pay from code 1257L. The remaining taxable pay is rounded down to whole pounds. The unrounded amount selects the Tables B to D formula against Cvalues rounded up to pounds; that formula retains the exact fractional Month-1 taxable-pay threshold and threshold tax until the final result is rounded down to a penny.

The member’s true position is nothing like that. With no other income, £30,000 less the full £12,570 personal allowance leaves £17,430, all within the basic rate band: £3,486 of tax. The month-1 code has taken £8,392.20 too much — an effective 39.6% deduction on a payment whose real liability runs at 11.6%. The common spreadsheet trap is to construct three rounded mini-bands from annual income-tax thresholds. PAYE does something more specific: code-derived Table A free pay first, then whole-pound taxable pay and exact fractional taxable-pay thresholds in the selected Tables B to D formula. The pension emergency tax calculator computes the month-1 deduction, true liability and reclaimable difference. The emergency-tax and reclaim guide covers the timing, evidence and HMRC form route.

Claiming it back: P55, P53Z or P50Z

The current form pages contain more than a two-way pot test. P55 requires all three of these facts: the pot was not emptied, no further regular or flexible payment is expected before the tax-year end, and the pension body cannot make the refund. After the whole pot is emptied, compare P53Z and P50Z against their current pages. P50Z contains work, unemployment-duration, retirement, former-employer-pension, study, income, timing and named-benefit alternatives or exclusions; P53Z asks for the pension P45 and expected income. A compact calculator cannot infer that declaration reliably, so the tool shows both rather than presenting a false deterministic answer.

Doing nothing also works. PAYE is reconciled after the year end, and HMRC repays any overpaid tax through the normal end-of-year process without a claim — the forms exist to accelerate the repayment into the tax year, not to create the entitlement. The over-deduction is the member’s money either way; the only question a form answers is when it comes back.

Further payments from the same scheme

The month-1 code is a first-payment problem. Once HMRC has issued the scheme a tax code, later payments from the same scheme are taxed on a cumulative basis — each payment is computed against the year-to-date allowance and bands, so the earlier over-deduction unwinds through the year of its own accord for a member drawing a regular income. That cuts the other way for one-off planning: where a further regular or flexible payment is planned before 5 April, the current P55 conditions are not met. A later cumulative computation may also unwind some of the earlier deduction. What the withdrawal itself costs in tax — as opposed to what PAYE borrows up front — is worked in the pension withdrawal tax calculator, and the wider context in pension withdrawals: how taking money out is taxed.
