Emergency tax on pension withdrawals calculator
What the 1257L month-1 emergency code takes from a first flexible pension payment, the tax the year actually owes, the reclaimable difference — and whether P55, P53Z or P50Z claims it back.
Free, no sign-up. Runs the same engine and the same versioned tax-year config the signed-in suite uses — nothing leaves your browser. How we verify the numbers.
One payment, two computations.
For a UFPLS enter only the 75% taxable element — the tax-free cash never enters PAYE.
Salary, State Pension, other pensions in payment — gross. Sets the true annual liability only; the month-1 deduction ignores it.
The allowance and bands come from the year’s versioned config.
Affects the annual liability only — the emergency code itself is UK-wide.
Routes the reclaim form: a part withdrawal leaves P55; emptying the pot leads to P53Z or P50Z.
Only consulted when the pot is emptied: other taxable income routes to P53Z; none routes to P50Z.
Later payments from the same scheme are taxed cumulatively — flagged for review; doesn’t change the figures.
Working from a gross withdrawal rather than the taxable element? The pension withdrawal tax calculator performs the 25/75 split for you.

— In short
The first flexible payment from a pension is usually over-taxed because the scheme must operate the 1257L emergency code on a month-1 basis (PAYE94055): only one-twelfth of the personal allowance and of each rate band is set against the whole payment, as though it recurred every month. The over-deduction is provisional PAYE timing, not the year’s liability — it is reclaimable in-year on form P55, P53Z or P50Z, or repaid through HMRC’s end-of-year reconciliation.
— How it's calculated
The month-1 mechanic — one-twelfth of everything
On the first flexible payment, HMRC instructs the scheme to operate the emergency code on a non-cumulative week-1/month-1 basis. Only one-twelfth of the personal allowance (£1,047.50 of the £12,570 behind code 1257L) and one-twelfth of each rate band is set against the whole payment, so a one-off is taxed as though it were one month of an annual income. On a £30,000 taxable payment with no other income, the code deducts £11,931.25 at source against a true year liability of £3,486 — an over-deduction of £8,445.25. 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. Residence 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.

Three questions route the reclaim form
An in-year claim runs on one of three gov.uk forms, selected by two facts. Pot not emptied — a part withdrawal remains invested — routes to P55 (‘Claim back tax on a flexibly accessed pension overpayment’). Pot emptied with other taxable income in the year routes to P53Z (‘Claim a tax refund when you’ve flexibly accessed all of your pension’). Pot emptied with no other taxable income routes to P50Z (‘Claim a tax refund if you’ve stopped work and flexibly accessed all of your pension’). Where a further payment from the same scheme is due before 5 April, the scheme operates PAYE cumulatively on the later payment, so part of the variance can come back at source; without any claim, HMRC repays through the end-of-year reconciliation.

— Worked example
- Month-1 PAYE deducted at source (provisional)
- £11,931.25
- True annual liability on the payment
- £3,486.00
- Over-deducted — reclaimable
- £8,445.25
- Reclaim form
- P55
Figures computed live by the same engine the tool above runs. The month-1 code sets one-twelfth of the personal allowance (£1,047.50) and of each band against the whole payment, pushing most of it into the 45% band; the year’s true position uses the full allowance and full bands, where the same £30,000 sits almost entirely at basic rate.
— 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): the scheme sets only one-twelfth of the personal allowance and of each rate band against the whole payment, as though it 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 in-year claim or through HMRC’s end-of-year reconciliation.
How do I claim emergency tax back on a pension?
In-year, by submitting the gov.uk form that matches the position: P55 where the pot has not been emptied, P53Z where the whole pot has been emptied and there is other taxable income, or P50Z where the whole pot has been emptied and there is no other taxable income. Without a claim, the overpayment is repaid through HMRC’s automatic end-of-year reconciliation for the tax year.
Which form — P55, P53Z or P50Z?
Two facts route the form. Pot not emptied: P55 (‘Claim back tax on a flexibly accessed pension overpayment’). Pot emptied with other taxable income in the year — employment, other pensions in payment: P53Z (‘Claim a tax refund when you’ve flexibly accessed all of your pension’). Pot emptied with no other taxable income: P50Z (‘Claim a tax refund if you’ve stopped work and flexibly accessed all of your pension’).
How long does the pension tax refund take?
There are two routes. An in-year claim on the correct form (P55, P53Z or P50Z) is repaid by HMRC once the claim is processed. Without a claim, the overpayment comes back automatically through HMRC’s end-of-year reconciliation after the tax year closes. Where a further payment from the same scheme is due before 5 April, the scheme’s cumulative PAYE on the later payment can also return part of the variance at source.
