Pension Withdrawal Tax Calculator UK: Tax and Refund Due

When you take money out of a defined contribution pension, usually 25% is tax-free and the rest is added to your income for the year. The catch: on a first withdrawal, most providers tax you on an emergency "month 1" basis, as if you would receive the same amount every month, so a one-off lump sum is often heavily over-taxed. Enter the withdrawal and your other income to see the tax you really owe, what is likely to be deducted at payout, and how much to reclaim from HMRC. Uses 2026/27 income tax bands for England, Wales and Northern Ireland.

How the calculation works

Tax you really owe is the extra income tax caused by the withdrawal: the tax on your other income plus the taxable part of the withdrawal, minus the tax on your other income alone. It uses the £12,570 personal allowance (reduced by £1 for every £2 of income above £100,000), 20% basic rate on the next £37,700, 40% higher rate up to £125,140 and 45% above that. These thresholds are frozen, so the same figures apply in 2025/26 and 2026/27.

Tax deducted at payout on a first payment assumes the provider uses the emergency code 1257L on a month 1 basis: one twelfth of the personal allowance and of each band, applied to this single payment. That is why a £30,000 taxable payment can have close to £12,000 taken off when the real bill for someone with no other income is £3,486. Small pot lump sums are different: the provider deducts a flat 20% on the taxable part with no allowance at all.

If too much is taken, you do not have to wait for the end of the tax year. HMRC has three repayment forms for flexible withdrawals: P55 if you took part of your pot and will not take more this year, P53Z if you emptied the pot and have other income, and P50Z if you emptied the pot and have no other income. Overpaid tax on a small pot lump sum is reclaimed with form P53. If too little is deducted, HMRC will normally collect it through your tax code or Self Assessment.

Two more points. Taking a UFPLS or any taxable drawdown income triggers the Money Purchase Annual Allowance, which cuts the amount you can pay into defined contribution pensions with tax relief to £10,000 a year; taking only tax-free cash or a small pot lump sum does not. And tax-free cash is capped across all your pensions by the Lump Sum Allowance of £268,275 unless you hold a protection. Scottish taxpayers pay different income tax rates, so this calculator will understate or overstate their bill.
