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, £11,931.25 leaves at source against a true annual liability of £3,486 — an over-deduction of £8,445.25 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 means one month’s slice of everything: one-twelfth of the £12,570 personal allowance and one-twelfth of each rate band, with anything above taxed at the additional rate. For 2026/27 the free pay is £1,047.50; the 20% band’s twelfth is £3,141.67 (£37,700 ÷ 12); the 40% band’s twelfth is £6,239.17 — one-twelfth of the £74,870 the 40% band actually spans, being the £125,140 additional-rate threshold less both the allowance and the basic band; and everything beyond falls at 45%.

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 £8,445.25 too much — an effective 39.8% deduction on a payment whose real liability runs at 11.6%. One construction detail catches DIY spreadsheets: the £125,140 threshold is a total-income figure that already contains the personal allowance, so a 40% twelfth built as (£125,140 − £37,700) ÷ 12 — forgetting to subtract the allowance — lands at £11,878.87 and is wrong. The pension emergency tax calculator computes the month-1 deduction, the true liability and the reclaimable difference for any payment.

Claiming it back: P55, P53Z or P50Z

Which form applies is a matter of two facts — whether the pot was emptied, and whether the member has other taxable income this year. P55 is the claim where the member has taken a payment but has not emptied the pension pot — a part withdrawal, with the rest staying invested. P53Z applies where the member has flexibly accessed all of the pension — the pot is emptied — and still has other taxable income in the year: continuing employment, another pension in payment, taxable benefits. P50Z applies where the pot is emptied and the member has no other taxable income — typically stopped work, with this the year’s only taxable receipt. Those are the gov.uk criteria verbatim in substance; picking the wrong form does not change the sum recoverable, only the processing.

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 payment from the same scheme is planned before 5 April, an in-year reclaim submitted now may be overtaken by the cumulative computation on the next payment. That is a timing fact for the adviser to weigh, not a recommendation either way. 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.
