Should I take the 25% tax-free lump sum?

The 25% pension commencement lump sum (PCLS) is the most over-taken benefit in UK pensions. The default is to take it as cash on day one, often with no plan for what to do with the money. That can be the right call. It can also cost six figures over a 25-year retirement. Here's the framework that drives the decision.

The short answer

Take it only if you have a use for the cash that beats keeping it inside the pension wrapper.

Inside the pension, the 25% slice grows tax-free. Once taken, the cash sits in a taxable wrapper (savings account, GIA, ISA only up to £20,000/year). For most people without an immediate need for the lump, leaving the slice inside the pension and drawing it gradually as part of normal income beats taking it on day one. The tax-free lump sum calculator models the exact difference for any pot size.

The four reasons that justify taking it

  1. Clearing the mortgage or other expensive debt. Saving 5–6% guaranteed mortgage interest in post-tax pounds can beat continued tax-free growth inside the pension at expected investment returns. Use the mortgage calculator for the exact saving.
  2. Funding a big planned expense. A house purchase, a major home improvement, helping a child onto the housing ladder, paying for a once-in-a-lifetime expense. The lump sum is genuinely free of income tax for these uses.
  3. Avoiding higher tax in early retirement years. If you're retiring at 60 with no other income for five years before State Pension starts, drawing the lump sum spread across those years uses up the personal allowance more efficiently than waiting and then drawing larger taxable amounts later.
  4. Taking advantage of an unusually high market. If equities are visibly over-valued at your target retirement date, locking in the 25% slice at the top can reduce sequence-of-returns risk for the remaining 75%.

The four reasons NOT to take it

  1. You don't have a use for the cash. Once it leaves the pension, it sits in a taxable wrapper. £100,000 in a savings account at 4% generates £4,000 of taxable interest a year — and on a higher-rate taxpayer, that's £1,600 of tax annually that wouldn't have applied inside the pension.
  2. You're worried about IHT on your estate. Pensions sit outside your estate for IHT purposes (until April 2027 — the position changes from then). Lump sums withdrawn into your bank account are inside the estate immediately. Drawing more than you need accelerates the IHT problem.
  3. You'd just reinvest it. If the plan is "take it out and put it in an ISA" — you're probably wrong on the maths. The £20,000 annual ISA cap means it would take 5 years to shelter a £100,000 lump, and meanwhile the un-sheltered portion is generating taxable interest or capital gains. Better to leave the lump inside the pension and use the annual ISA allowance from elsewhere.
  4. You're between £268,275 and the old LTA. The 25% tax-free slice was capped at £268,275 from April 2024. If your pot is £1.2M, you can't take 25% of it tax-free — only £268,275. Taking the lump triggers the cap. Sometimes splitting the access strategically across several pensions or years helps; this is a question for a fee-only IFA.

Worked example — £400,000 pension at 60

Sam, age 60. Total DC pension £400,000. Plans to retire fully at 65, currently working part-time earning £20,000. State pension starts at 67 at about £11,500/year.

Option B leaves Sam with about £25,000 more across retirement, with no offsetting downside. The reason: Option A's cash sits in a less-efficient wrapper for 5 years.

If Sam needs the cash to clear a £100,000 mortgage at 5.5%, Option A wins by saving £30,000+ of mortgage interest over 5 years. The right answer depends entirely on the cash use.

The post-April-2027 IHT change

From 6 April 2027 (under current legislation), defined-contribution pension pots become part of the estate for inheritance tax purposes — a significant change that turns pension wrappers from one of the most IHT-efficient holdings into one of the least. This shifts the calculus on lump sums.

Specifically: if your pension is large enough that the £325,000 nil-rate band plus £175,000 residence nil-rate band won't cover your estate, taking the 25% tax-free lump sum and gifting it under the seven-year rule may save more in IHT than the lump sum costs in lost tax-free growth.

The IHT guide covers the seven-year rule. The gift tracker models the actual saving from a series of gifts. This is genuinely a "fee-only IFA" decision — the variables are individual and the stakes are six-figure.

Frequently asked questions

The questions readers most commonly ask about this topic. Each answer is reviewed by the UK Tax Drag editorial team against current HMRC, FCA and MoneyHelper guidance.

▸ Is the 25% tax-free lump sum guaranteed for everyone?

It's available to all UK registered pension scheme members from age 55 (rising to 57 in April 2028), but the absolute amount is capped at £268,275 (the Lump Sum Allowance) for most people. If you took benefits before 6 April 2024 you may have a "transitional certificate" giving a different cap. The 25% applies to each individual pension's value at the point you crystallise it.

▸ Should I take the full 25% as a lump sum in one go?

Not necessarily. Taking it all up front locks in the tax-free amount but starts taxable income tracking on the remaining 75%. Alternative: use UFPLS (Uncrystallised Funds Pension Lump Sum) to take chunks — each chunk is 25% tax-free and 75% taxable. This lets you stage the tax-free element over multiple years, useful for managing income tax bands.

▸ What if my pension grows after I take the 25%?

If you take 25% from a "crystallised" pot, that pot then goes into flexi-access drawdown. Future growth is taxable as income when withdrawn — there's no second 25% on growth on the same crystallised pot. If you have multiple pension pots, you can crystallise them one at a time, taking 25% from each at different ages.

▸ Can I use the lump sum to pay off my mortgage?

Yes — and it's tax-free, so there's no immediate tax cost. But consider opportunity cost: mortgage rates in 2026 are typically 4-5% on remortgages; pension growth might be 4-6% real return. Paying off a mortgage gives a guaranteed return equal to the mortgage rate; leaving in pension gives potential higher returns with risk. Mid-50s borrowers near the end of their mortgage often choose payoff for simplicity.

▸ What's the 2025 Budget impact on the tax-free lump sum?

The 25% rule itself was not changed in the November 2024 Budget — but the £268,275 Lump Sum Allowance is a hard cap that was confirmed. Pre-Budget there had been speculation about reducing the 25% to 20% or capping at £100,000; neither happened. The political fragility means many savers near the cap took action in late 2024 — this was a one-time event, not recurring planning.

▸ Can I take the 25% and still contribute to a pension?

Taking the 25% tax-free element WITHOUT taking any taxable income preserves your full £60,000 annual allowance. Once you take ANY taxable income from a flexible drawdown pot, you trigger the Money Purchase Annual Allowance (MPAA), reducing future pension contributions to £10,000/year. If you might still earn and contribute, take only the tax-free element until you're definitely retired.
