The 25% tax-free pension lump sum

The most valuable feature of the UK pension system, and the one where mistakes are hardest to undo.

Retirement · Updated for 2026/27

From age 55 you can normally take a quarter of a defined contribution pension without paying any tax on it. It is the most valuable feature of the UK pension system and also the one where irreversible mistakes are easiest to make.

How the two halves are taxed

The tax-free quarter does not use up your personal allowance and does not count as income. The other 75% is added to your other taxable income for that year and taxed at your marginal rate, using the same bands that apply to wages.

This matters more than most people expect, because the State Pension already uses most of the personal allowance. At £241.30 a week, the full new State Pension is around £12,548 a year against a £12,570 personal allowance — so almost every pound of taxable pension income on top of it is taxed from the first pound.

Two ways to take it, and why the choice matters

Lump sum then drawdown. You take the full 25% in one go, and the remaining pot moves into drawdown where every later withdrawal is fully taxable.

Phased, or UFPLS. You take smaller amounts, and 25% of each withdrawal is tax-free with 75% taxable. This spreads the tax-free element across many years and leaves more invested.

The phased approach is often more tax-efficient, because it lets you keep each year's taxable income inside the basic-rate band instead of pushing a large sum into 40% territory in a single year. Taking a very large taxable amount in one tax year is one of the most expensive avoidable mistakes in retirement.

The emergency tax shock

Your first taxable pension withdrawal is very likely to be over-taxed. HMRC systems apply a month-1 emergency code that treats the payment as though you will receive the same amount every month for the rest of the year, projecting a one-off £20,000 as if it were £240,000 of annual income.

The money is reclaimable. Depending on your circumstances you use form P55, P53Z or P50Z, and HMRC typically processes refunds within four to six weeks. If you do nothing, the year-end reconciliation should correct it eventually, but that can take until the following autumn. The tax-free 25% is never affected — the emergency code only ever touches the taxable portion.

The MPAA trap for anyone still working

Taking any taxable income from a defined contribution pension triggers the Money Purchase Annual Allowance. From that moment your annual allowance for future DC pension contributions drops from £60,000 to £10,000, permanently — it cannot be un-triggered, and carry-forward of unused allowance no longer applies.

If you are still working and contributing meaningfully, this can be very costly. Three things do not trigger it: taking only the 25% tax-free lump sum on its own, buying a lifetime annuity, and small-pot lump sums of up to £10,000 from non-occupational schemes.

Should you take it at all?

There is no requirement to. Money left in the pension continues to grow in a tax-advantaged environment, and the 25% entitlement does not expire. Taking a large lump sum to hold in a bank account, where it earns taxable interest and loses value to inflation, is rarely the stronger option unless you have a specific use for it.

Good reasons to take it include clearing a mortgage, funding a genuine early-retirement bridge before the State Pension starts, or a planned major expense. "Because I can" is not one.
