Whether you should take your tax-free pension lump sum now depends on what you’d actually do with the cash. You can withdraw up to 25% of your pension pot free of income tax, capped at £268,275 across all your pensions combined.1GOV.UK. Tax When You Get a Pension: What’s Tax-Free The money itself is genuinely tax-free, but the decision isn’t only about tax. Pulling that cash out shrinks the pot generating your future income, moves the money into your taxable estate for inheritance tax, and can quietly restrict how much you’re allowed to pay back into a pension later. If none of those consequences worry you and you have a real use for the money, taking it can be the right call. If you’re pulling it out because you’re entitled to it and not sure what else to do, leaving it invested is usually better.
When Taking It Now Makes Sense
The clearest case is a specific, costly need the lump sum solves. Clearing a mortgage is the textbook example: the monthly repayment would otherwise eat into your drawdown income for years, so removing that expense can improve your overall position even though the pot shrinks.
There is also a policy change on the horizon. The government has announced that from April 2027, unused pension funds passed on at death will be brought within the scope of inheritance tax. If that goes ahead as planned, one of the strongest reasons to leave money inside a pension weakens considerably. Some advisers point to this when suggesting the lump sum be taken sooner. The final rules are still being finalised, so the weight you give this depends on your own timeline and estate.
Why Leaving It Alone Often Wins
Money inside a pension sits outside your estate under current inheritance tax rules. The moment you withdraw a lump sum and put it in a bank account, it becomes part of your taxable estate. Inheritance tax is charged at 40% on anything above the £325,000 nil-rate band.2GOV.UK. How Inheritance Tax Works: Thresholds, Rules and Allowances If your estate is already close to that threshold, a £100,000 lump sum sitting in savings could generate a £40,000 tax bill that wouldn’t have existed if the money had stayed put.
The pension wrapper also shelters investment growth from capital gains tax, so money left inside compounds more efficiently than the same amount in a taxable account. On a £400,000 pot, taking the full £100,000 tax-free lump sum leaves £300,000 to fund what might be 30 or more years of retirement. At a modest 4% annual return, that £100,000 would have grown to roughly £132,000 after seven years if left invested.
The future income effect is straightforward. If you plan to buy an annuity, a smaller pot buys a smaller guaranteed income. If you plan to draw down, a common guideline is to withdraw around 3.5% to 4% of your pot each year to avoid running out. On £400,000 that’s roughly £14,000 to £16,000 a year; on £300,000 it’s roughly £10,500 to £12,000. That gap compounds across decades.
The £268,275 Cap and What Counts Toward It
The Finance Act 2024 replaced the Lifetime Allowance with a Lump Sum Allowance, capping tax-free cash across all your pensions at £268,275.3Legislation.gov.uk. Finance Act 2024 The 25% rule still applies to each pot, but someone with pensions totalling roughly £1.07 million or more won’t get 25% of the total tax-free.
Any tax-free lump sums you took before 6 April 2024 under the old rules count against this ceiling.3Legislation.gov.uk. Finance Act 2024 If you already received £100,000 tax-free in earlier years, your remaining allowance is £168,275. Anything beyond the cap is taxed at your marginal income tax rate — 20%, 40%, or 45% depending on your total income for the year.4GOV.UK. Income Tax Rates and Personal Allowances Before requesting anything, ask each provider how much of your allowance you’ve already used.
The Contribution Trap to Avoid
This one catches people out. Taking only the 25% tax-free lump sum and leaving the rest untouched does not trigger the Money Purchase Annual Allowance. The trigger is taking taxable flexible income from a defined contribution pension: drawdown income, further taxable lump sums, or cashing in the whole pot. Once triggered, the amount you can pay into any money purchase pension and still get tax relief drops from £60,000 a year to £10,000.5MoneyHelper. The Money Purchase Annual Allowance (MPAA) for Pension Savings
The practical implication: someone who takes their full tax-free cash and then withdraws even a small amount of taxable drawdown income permanently locks themselves into the £10,000 contribution limit. If you’re still working, planning to return to work, or have self-employment income you’d like to shelter, keep the taxable portion of your pot completely untouched.
Taking the Cash in Stages
You don’t have to take the full 25% in one transaction. Most defined contribution schemes let you crystallise your pension in stages, taking 25% tax-free from each portion as you go. On a £400,000 pot you could crystallise £100,000 now, take £25,000 tax-free, and leave the remaining £300,000 untouched. Years later you crystallise another slice and take another 25% tax-free from that.
The uncrystallised portion keeps growing inside the pension. You only pull money into your estate when you actually need it. And if you die before crystallising the whole pot, the uncrystallised portion passes to your beneficiaries under the pension’s death benefit rules rather than forming part of your estate under current inheritance tax rules.
A simpler alternative is an Uncrystallised Funds Pension Lump Sum, where each withdrawal is automatically split 25% tax-free and 75% taxable. It’s easier to administer but does trigger the Money Purchase Annual Allowance, because each payment includes taxable flexible income. If preserving your future contribution allowance matters, phased crystallisation gives you more control.
When You’re Allowed to Take It
You generally cannot access pension savings until the normal minimum pension age, currently 55.6HM Revenue & Customs. Increasing Normal Minimum Pension Age From 6 April 2028 that rises to 57. If you were born after 5 April 1973, you won’t qualify at 55 and will have to wait until 57.
Two exceptions. If your scheme gave you the right to take benefits before age 55 on or before 5 April 2006, you may hold a protected pension age that lets you access your pot earlier.7HM Revenue & Customs. Pensions Tax Manual – PTM062205 – Member Benefits: Pensions: Protected Pension Age: Basic Principles This commonly applies to professions with traditionally low retirement ages. And if you’re permanently unable to carry out your job because of illness or disability, your scheme’s trustees can approve ill-health retirement at any age, provided you supply satisfactory medical evidence.
Requesting the Lump Sum
If you’ve decided to go ahead, contact your provider and ask for the current pot value along with a benefits illustration showing your tax-free entitlement. You’ll need your pension account reference and National Insurance number. The provider sends a form asking you to specify the amount or percentage and the bank details for payment.
Providers must complete identity verification and anti-money laundering checks before releasing funds. Most transfers complete within five to ten working days once the paperwork is in order. If you hold pensions with several providers, each handles its own lump sum, and every withdrawal counts toward the £268,275 Lump Sum Allowance.1GOV.UK.
