Pension Lump Sum Calculator (PCLS)

The Pension Commencement Lump Sum (PCLS) entitles you to withdraw 25% of your crystallised pension pot completely free of income tax. For defined contribution pensions, the PCLS is simply 25% of the pot value at the point of crystallisation, so a £500k pot yields £125,000 tax-free and leaves £375,000 that is taxable when drawn. You can crystallise your pension in stages (phased drawdown), taking 25% tax-free from each tranche, which can be more tax-efficient than crystallising everything at once. The right to take the money this way, in one lump or in phases, dates from the 2015 Pension Freedoms, and it opens at age 55, rising to 57 in April 2028.

Withdrawals above the 25% PCLS are taxed as earned income. The tax calculation adds the taxable withdrawal to your other income for the year, including any State Pension, then applies the standard income tax bands: 0% on the personal allowance (£12,570), 20% basic rate (£12,571 to £50,270), 40% higher rate (£50,271 to £125,140) and 45% additional rate (above £125,140). A retiree with the full new State Pension of £12,547.60 and £25,000 of drawdown has £37,547.60 of total income, of which £24,977.60 sits above the personal allowance and is taxed at 20%, giving a bill of £4,995.52. Emergency tax coding on first withdrawals often results in overpayment that must be reclaimed.

Uncrystallised Funds Pension Lump Sum (UFPLS) is an alternative where you take a lump sum directly without entering drawdown. Each UFPLS payment is 25% tax-free and 75% taxable, which suits people who want phased lump sums while keeping the rest invested. Taking one triggers the Money Purchase Annual Allowance (MPAA) of £10,000, restricting future contributions. Flexi-access drawdown works the other way round: you take the 25% lump sum upfront and draw the remaining 75% as taxable income over time, which is better for those who want a big sum now and a smaller income over the years. An annuity buys a guaranteed income for life, and the three can be combined, for instance 25% tax-free, a small annuity to cover essentials, and drawdown for the remainder.

Since April 2024 the Lifetime Allowance has been replaced by a Lump Sum Allowance, which caps the total tax-free cash you can take across all your pensions at £268,275 in your lifetime (25% of the old standard lifetime limit). A pot worth more than £1.073M is therefore capped at £268,275 tax-free regardless of its size. The tax-free lump sum does not have to be taken immediately, either. Leaving it phased keeps more money invested for tax-free growth, spreads the tax-free element across several years and preserves flexibility for medium-term needs. Taking the full 25% upfront makes sense if you want to clear a mortgage or other debt, fund a large purchase or build an emergency fund. The general advice is to take only what you need and leave the rest invested.

Planning the taxable 75% is largely about the bands. Keeping total income, State Pension included, under £50,270 means every pound of pension is taxed at 20% rather than 40%. The higher-rate marginal cost of 40% on pension income is the equivalent of working another year for 60p in the pound. Spreading withdrawals across tax years helps: taking £30k in March and another £30k in April puts the same money into two different tax years. The first year of retirement may need a larger lump sum for the transition, with subsequent years kept inside the basic-rate band. There is also sequence-of-returns risk to consider, since a market crash early in retirement combined with heavy withdrawals can exhaust a pension decades earlier than a safer pace would.

Death benefits are the other half of the picture. A pension can be inherited tax-free if you die before 75, provided it falls under the £1.073M death benefit allowance, and is taxed at the recipient's own rate if you die after 75. Pensions sit outside the estate for inheritance tax only until 5 April 2027: under the Finance Act 2026, unused funds count towards the estate for deaths from 6 April 2027, so leaving the pot untouched to pass on is a weaker plan than it was, and drawing it down or spending it before other savings can now make more sense.
