Why was my pension withdrawal taxed so heavily?

Without a current tax code the provider must use the emergency code on a month-1 basis: one twelfth of the personal allowance and of each tax band is applied to the single payment, as if you would receive it every month. A one-off lump sum therefore lands mostly in the 40% and 45% bands. A £30,000 UFPLS taken by someone with £15,000 of other income loses about £7,700 on the day against roughly £4,500 actually due.

How do I claim emergency tax back on a pension?

In the same tax year, use form P55 for a partial withdrawal, P53Z if you emptied the pot and have other income, or P50Z if you emptied it and have none; HMRC usually repays within 30 days. If you do nothing, PAYE reconciliation refunds it after the tax year ends.

How can I avoid emergency tax on a pension withdrawal?

Take a small first payment so the provider receives a proper tax code before the large one, or spread withdrawals across tax years so each stays within lower bands. Since April 2025 HMRC updates codes faster after a first pension payment.

How month-1 taxation works

PAYE is designed for salaries. Without an in-date code from a previous pension payment, the provider must use the emergency code (1257L, or S1257L in Scotland) on a non-cumulative basis: this payment gets one twelfth of the personal allowance and one twelfth of each band, and everything above is taxed at the higher and additional rates. It is not a mistake by the provider; it is the rule, and the over-deduction is yours to reclaim.

Reclaiming, or not paying it in the first place

Three forms cover the in-year reclaim: P55 for a partial withdrawal, P53Z when the pot is emptied and you have other income, P50Z when it is emptied and you have none. Better still is to avoid the problem: a small first withdrawal triggers a proper code, and spreading a large sum across tax years keeps more of it in the basic band. The Hundred Summers app’s Pension Income tab stacks withdrawals against your other income year by year; the tax-free lump sum calculator compares taking the 25% up front against UFPLS slices.
