25% Tax-Free Cash vs Leaving Money in Your Pension — Is It Worth Taking?
The Pension Commencement Lump Sum (PCLS) lets you take up to £268,275 tax-free from your pension in 2026/27. On a £400,000 pot that means £100,000 completely free of income tax. But taking that cash also means losing the compound growth it would generate inside the pension wrapper, potentially triggering the Money Purchase Annual Allowance if you are not careful, and leaving the remaining 75% fully taxable when you draw it. This guide models when the PCLS is worth taking, when leaving it invested pays more, and how the ISA re-sheltering strategy works.
Take Tax-Free Cash vs Leave It Invested — Key Trade-offs
| Factor | Take Tax-Free Cash (PCLS) | Leave in Pension |
|---|---|---|
| Immediate tax saving | Yes — up to £268,275 with zero income tax | No immediate saving — taxed when drawn |
| Compound growth | Lost on the portion withdrawn | Continues tax-free inside the wrapper |
| MPAA risk | Safe if PCLS only (no income drawn from drawdown) | No MPAA until taxable income drawn |
| IHT position (pre-Apr 2027) | Cash in estate — potentially taxable at 40% | Pension pot outside estate — no IHT |
| IHT position (post-Apr 2027) | Broadly neutral (pension pot also becomes taxable) | Broadly neutral |
| Income tax on remaining 75% | Taxed at marginal rate when drawn from drawdown | Taxed at marginal rate when drawn from drawdown |
| Flexibility | Immediate access to cash — no income tax | Must draw taxably to access (or PCLS later) |
| Re-sheltering option | Can move into ISA (£20k/yr per person) | Already in tax-efficient wrapper |
| Timing strategy | Take in low-income year to minimise opportunity cost | Defer; pot may continue growing substantially |
What Is the PCLS (Pension Commencement Lump Sum)?
The PCLS is the tax-free lump sum you can take when you first access (crystallise) a pension fund. In 2026/27 the rules are:
- Maximum tax-free cash: 25% of the crystallised fund
- Lifetime cap: the Lump Sum Allowance (LSA) of £268,275 across all pots and all crystallisation events
- Above the LSA: any further tax-free lump sums are taxed at your marginal income tax rate (not a fixed rate)
- The Lifetime Allowance was abolished from April 2023 — so there is no cap on total pension pot size, only on the tax-free cash amount
- Protected tax-free cash (from before April 2006 or from protection certificates) may allow a higher tax-free sum — check your scheme documents
Worked Example: £400,000 Pension Pot at Retirement (Age 60)
David, 60, has a £400,000 defined contribution pension. He is considering taking £100,000 PCLS (25%) vs leaving it invested.
| Scenario | Take £100k PCLS now | Leave all £400k invested |
|---|---|---|
| Tax-free cash received today | £100,000 | £0 |
| Remaining pot in drawdown | £300,000 | £400,000 |
| Projected pot at age 75 (5%/yr, 15 years) | £300k → £624,000 | £400k → £832,000 |
| Additional growth on £100k if left in pension (5%/yr, 15yr) | — | +£208,000 (pot value: £832k vs £624k) |
| Tax-free cash equivalent at age 75 (25% of larger pot) | — | £208,000 tax-free possible |
| Tax on drawdown at basic rate (20%) | Pay 20% on £624k drawdown | Pay 20% on £832k drawdown |
| Effective advantage of leaving invested (pre-tax) | — | ~£208k extra in pot |
Illustrative only. 5%/yr real growth assumption; not guaranteed. Tax treatment assumes basic-rate drawdown income. If David needs the cash now for spending or debt repayment, the tax-free cash is genuinely valuable — do not leave money in a pension simply to defer tax if you have an immediate use for the capital.
The ISA Re-Sheltering Strategy
If you take the PCLS and do not need the cash immediately, re-sheltering it into an ISA is a common strategy:
- Take £100,000 PCLS over 2–3 tax years (£20,000 into ISA each year for yourself, plus £20,000 for a spouse = £40,000/year)
- Inside the ISA, growth is free of income tax, CGT, and dividend tax
- ISA withdrawals are tax-free at any time — unlike drawdown which is always taxable
- Under current rules ISA funds are in the estate (subject to IHT), whereas the pension pot is not — but post-April 2027 this distinction narrows
- The ISA re-sheltering strategy is particularly powerful for those with large pots who expect marginal rates to rise, or who want more flexible tax-free access in retirement
Key caveat: ISA allowances are per tax year — you cannot backdate contributions. Plan the re-sheltering over the years when you crystallise the pension, not all at once.
Defined Benefit Schemes: Commutation
For defined benefit (DB) pensions — final salary or CARE schemes — tax-free cash works differently. You take it by commuting (giving up) some annual pension. The commutation factor (CF) is the key number:
- CF 12:1: give up £1,000/year pension to receive £12,000 lump sum. Not usually worth it — £1,000/year pension over 20 years = £20,000 of income given up to save perhaps £4,800 in tax (at 40% on £12k)
- CF 20:1: give up £1,000/year pension to receive £20,000 lump sum. Potentially worth considering if you have a specific use for capital, expect lower life expectancy, or have other pension income to rely on
- Generally: public sector DB commutation factors (NHS, teachers, civil service) tend to be 12:1 — below the typical breakeven point. Private sector schemes vary widely
- Pre-2006 protected cash: some DB members have a protected right to a specific lump sum without commuting pension — typically 3× the annual pension. This is often more generous and should be taken rather than commuting further
Timing: Take Tax-Free Cash in a Low-Income Year
The tax-free cash itself has no income tax regardless of timing. However, the year you crystallise the pension affects:
- When you start the drawdown clock (and potentially trigger the MPAA if you draw income)
- How much of the remaining 75% is drawn in high or low marginal-rate years
- Whether you can use the current year's ISA allowance for re-sheltering
The optimal crystallisation year is typically one where other taxable income is low — perhaps early in retirement before State Pension begins, or in a year with large pension contributions that reduce taxable income. Model the drawdown income carefully over your expected retirement to minimise lifetime income tax on the 75%.

Frequently Asked Questions
What is the Lump Sum Allowance and how much tax-free cash can I take?
The Lump Sum Allowance (LSA) is £268,275 in 2026/27 — the maximum tax-free cash you can take across all your pension schemes in your lifetime. If you have protected rights (primary or enhanced protection, or individual protection from before the Lifetime Allowance was abolished in April 2023), your tax-free entitlement may be higher. For most people, the practical limit is 25% of their pension pot, up to £268,275 in total across all pots. Once the LSA is used up, any further lump sums from pensions are fully taxable at your marginal income tax rate.
Does taking tax-free cash trigger the Money Purchase Annual Allowance (MPAA)?
Taking tax-free cash alone from an uncrystallised pension fund — through an Uncrystallised Funds Pension Lump Sum (UFPLS) — triggers the MPAA, reducing your Annual Allowance for future money purchase pension contributions from £60,000 to just £10,000. However, using Pension Commencement Lump Sum (PCLS) alone — crystallising the fund and moving the rest into drawdown without actually drawing income — does not trigger the MPAA. The MPAA is only triggered when you start drawing taxable income from a drawdown fund or take a UFPLS. Taking PCLS and then leaving the remaining 75% in a drawdown wrapper uninvested is safe from an MPAA perspective.
Should I take all my 25% tax-free cash at once or in stages?
Taking tax-free cash in stages (phased drawdown) is often more tax-efficient than crystallising all at once. Each time you crystallise (move funds from uncrystallised to drawdown), you can take 25% of that tranche as PCLS. Spread across multiple tax years, this allows you to: manage the size of your taxable income in each year; avoid pushing income into higher-rate bands; and use your Personal Allowance (£12,570 in 2026/27) in years when other income is low. Example: if you have a £400,000 pot, crystallise £100,000/year over 4 years, taking £25,000 PCLS each time — total tax-free cash £100,000, taxable drawdown income managed carefully each year.

What is the ISA re-sheltering strategy for pension tax-free cash?
The ISA re-sheltering strategy involves taking the tax-free lump sum and placing it into an ISA (up to the £20,000 annual ISA allowance per tax year). Inside the ISA, funds grow entirely free of income tax, capital gains tax, and dividend tax — protecting the tax-free status of the capital without it sitting in cash or a taxable investment account. If you take £100,000 PCLS and have a spouse or partner, you can together contribute £40,000/year into ISAs. Over 2–3 years, most or all of the PCLS could be re-sheltered into ISAs. Note: once outside the pension, the re-sheltered funds do not benefit from the IHT-exempt status that pension funds currently enjoy (until April 2027 rule changes).
Is it better to leave money in the pension for IHT purposes?
Under rules in force before April 2027, unspent defined contribution pension funds pass to beneficiaries free of Inheritance Tax — making a pension pot a very efficient IHT planning vehicle. However, from April 2027 the Government proposes to bring inherited pension pots into the estate for IHT purposes. If these rules are enacted as proposed, the IHT advantage of leaving funds in a pension is significantly reduced. Under current (pre-2027) rules, leaving funds in the pension rather than taking PCLS and spending (or re-sheltering) them preserves IHT efficiency. From April 2027, this calculus changes — IHT planning advice from a financial planner is strongly recommended for those with estates above the nil-rate bands.
How does tax-free cash work for defined benefit (DB) schemes?
Defined benefit (final salary or CARE) schemes operate differently from defined contribution pensions. In a DB scheme, tax-free cash is typically provided by commuting (giving up) some annual pension. The commutation factor determines how much pension you give up per £1 of lump sum. Common commutation factors range from 12:1 (low — rarely worth commuting at this rate) to 20:1 (generous — often worth considering). For pre-2006 accrual in some DB schemes, there may be a separate "protected" tax-free cash entitlement of up to 3× the commuted pension. The financial impact of commutation depends on your health, life expectancy, other income, and the commutation factor — model carefully before deciding.
What happens to the remaining 75% after I take tax-free cash?
After taking PCLS, the remaining 75% of the crystallised fund is placed into a drawdown wrapper (Flexi-Access Drawdown). From drawdown, you can: (1) draw income at any time — taxed at your marginal income tax rate as earned income; (2) leave it invested and not draw any income — the drawdown fund continues to grow tax-free; (3) use it to purchase an annuity (guaranteed income for life) — taxable as income when paid; (4) designate it to a nominee on death — the beneficiaries can draw the funds (taxable at their marginal rate if you die after age 75, or tax-free if before age 75). There is no requirement to draw income after taking PCLS — many people take the tax-free cash and leave the drawdown fund invested for years.
Can I take tax-free cash and continue contributing to my pension?
Yes, with important caveats. Taking PCLS alone does not trigger the MPAA — you can continue contributing up to £60,000/year (the 2026/27 Annual Allowance) into money purchase pensions. However, if you crystallise a fund and start drawing taxable income from it (Flexi-Access Drawdown income or UFPLS), the MPAA is triggered — limiting future money purchase contributions to £10,000/year. To maximise future contribution capacity: take PCLS only, leave the remaining 75% in drawdown uninvested, and do not draw any taxable income until you have made all the pension contributions you intend to make. This preserves the full £60,000 Annual Allowance for additional pension saving.
