— Understanding the result
The first flexible payment from a pension is often over-taxed because, without a current-year P45 or HMRC code, the scheme operates the 1257L emergency code on a month-1 basis (PAYE94055). HMRC Table A gives the code’s month-1 free pay and Tables B to D apply the month-1 taxable-pay bands, as though the payment recurred every month. The over-deduction is provisional PAYE timing, not the year’s liability. Where the current eligibility conditions are met, an in-year claim may use P55, P53Z or P50Z; otherwise HMRC reconciles the position after the tax year.
— How it's calculated
The month-1 mechanic — HMRC Tables A to D
On the first flexible payment, without a current-year P45 or HMRC code, the scheme operates the emergency code on a non-cumulative week-1/month-1 basis. For 2026/27, Table A gives code 1257L £1,048.26 of free pay. Tables B to D then round the remaining taxable pay down to whole pounds and apply the month-1 taxable-pay thresholds. On a £30,000 taxable payment with no other income, the code deducts £11,878.20 at source against a true year liability of £3,486 — an over-deduction of £8,392.20. The deduction is provisional PAYE timing; it is never the liability itself.

The annual basis — what the year actually owes
The tax the payment actually attracts is the marginal difference: the year’s liability with the taxable element stacked on the member’s other income, minus the liability without it — computed with the full personal allowance and full bands, the £100,000 personal-allowance taper where the payment crosses it, and the Scottish non-savings bands for Scottish taxpayers. Scottish taxpayer status affects this leg only; the emergency code itself is UK-wide. This annual figure is what HMRC’s in-year repayment or end-of-year reconciliation settles to.
The answers identify the HMRC form to check
P55 is only available where 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. If the whole pot was emptied, check both P53Z and P50Z against their current pages. The P50Z declaration includes several work, unemployment-duration, retirement, former-employer-pension, study, income and benefit alternatives or exclusions that this compact tool does not infer. HMRC also asks for the pension P45 and gives timing rules. Without an in-year claim, HMRC reconciles the position after the tax year.

— How to work out emergency tax on a pension withdrawal
Step 1
Enter the taxable element of the payment
For a UFPLS that is the 75% taxable part — the 25% tax-free cash never enters PAYE. Drawdown income taken after the PCLS is taxable in full.
Step 2
Add the year’s other taxable income
Salary, State Pension and other pensions in payment feed the true annual liability only — the month-1 deduction ignores them entirely.
Step 3
Compare the month-1 deduction with the true liability
The month-1 figure uses Table A code-derived free pay, whole-pound taxable-pay rounding and the Month-1 Tables B to D thresholds. The difference against the annual figure is the modelled over-deduction — or an underpayment where other income puts the marginal rate above what the code assumed.
Step 4
Answer the routing questions
For P55, confirm that the pot was not emptied, no further regular or flexible payment is expected before 5 April, and the pension body cannot refund the tax. If the pot was emptied, check both P53Z and P50Z against the current GOV.UK declarations; this compact tool deliberately does not infer their work, study, retirement, income, pension, timing and benefit conditions.
— Worked example
- Month-1 PAYE deducted at source (provisional)
- £11,878.20
- True annual liability on the payment
- £3,486.00
- Over-deducted — reclaimable
- £8,392.20
- Likely reclaim route to check
- P55
Figures computed live by the same engine the tool above runs. For 2026/27, Table A gives 1257L Month-1 free pay of £1,048.26; Tables B to D round the remainder down to whole pounds and apply the Month-1 taxable-pay thresholds. The year’s true position instead uses the full allowance and annual bands.
— Frequently asked questions
Why was my pension taxed so much?
The first flexible payment from a pension is normally taxed under the 1257L emergency code on a month-1 basis (PAYE94055). HMRC Table A gives the code’s Month-1 free pay and Tables B to D apply the Month-1 taxable-pay thresholds, as though the payment recurred every month. A one-off payment therefore has most of its value pushed into the higher and additional rates at source. The deduction is provisional PAYE timing, not the year’s liability — the difference comes back by an eligible in-year claim or through HMRC’s end-of-year reconciliation.
How do I claim emergency tax back on a pension?
Start with the current GOV.UK eligibility checks. P55 requires the pot not to be emptied, no further regular or flexible payment before the tax-year end, and a pension body that cannot make the refund. If the whole pot was emptied, check both P53Z and P50Z: their current declarations include evidence, work, study, retirement, income, pension, timing and benefit conditions that this compact tool does not infer. Without an in-year claim, HMRC reconciles the position after the tax year.
Which form — P55, P53Z or P50Z?
The calculator identifies a route to check, not automatic eligibility. P55 needs all three current conditions: the pot was not emptied, no further regular or flexible payment is expected before 5 April, and the pension body cannot refund the tax. For a whole-pot case it shows P53Z and P50Z together because the current declarations contain detailed alternatives and exclusions that the calculator does not ask. Use the GOV.UK pages to make that final distinction.
How long does the pension tax refund take?
Where its current conditions are met, HMRC processes an in-year P55, P53Z or P50Z claim. Without a claim, HMRC reconciles the position after the tax year. If a further regular or flexible payment is expected before 5 April, P55 is unavailable on current GOV.UK guidance and a later cumulative PAYE calculation may also return part of the variance at source.
