Pension Tax-Free Cash (PCLS) Calculator

2. DC Pension PCLS — Straightforward 25%

For a defined contribution pension (SIPP, personal pension, group personal pension, stakeholder pension), the maximum PCLS is simply 25% of the fund value at the time of crystallisation — subject to the £268,275 LSA cap. You designate the remaining 75% to drawdown.

Example: Fund = £300,000. PCLS = £75,000 (25%). Drawdown fund = £225,000. At 4% sustainable withdrawal rate, that generates ~£9,000/year taxable income. At 5% = £11,250/year. You can vary your drawdown income each year, unlike an annuity.

Impact of fund size on LSA: A fund of £1,073,100 generates a PCLS of £268,275 — exhausting the entire LSA in one pension. Any larger fund, or combination of pensions, will see tax-free cash capped at £268,275 in total.

3. DB Pension PCLS — Commutation Factor Mechanics

For a defined benefit (DB) pension, you do not have a 'fund' in the same way. The PCLS is generated by commuting (surrendering) part of your annual pension in exchange for a lump sum. The commutation factor determines the exchange rate: a factor of 12 means £12 of lump sum per £1 of annual pension surrendered.

Example: Annual pension £20,000. Commutation factor 12. You surrender £5,000/year pension → PCLS = £5,000 × 12 = £60,000. Residual pension = £15,000/year. The question is whether the pension income foregone is worth more than the lump sum received — this depends on longevity, investment returns, and the value of flexibility.

HMRC limits the maximum PCLS from a DB scheme to ensure the 25% cap is not exceeded. The formula is complex and depends on whether the scheme provides a separate lump sum or a commutable pension. Always check with your scheme administrator for your specific entitlement.

4. Phased Crystallisation — Staged Tax-Free Cash Strategy

Instead of crystallising your entire pension at once, you can crystallise portions over multiple years. Each crystallisation generates PCLS equal to 25% of the crystallised amount (up to remaining LSA). The uncrystallised portion continues to benefit from tax-free investment growth inside the pension wrapper.

Why phase? (a) Manage taxable income each year — only crystallise what you need. (b) Keep more funds uncrystallised for death benefit purposes (income-tax-free to beneficiaries before age 75). (c) Smooth the tax charge over multiple years rather than crystallising a large fund all at once (relevant if crystallising above the LSA). (d) Benefit from continued pension fund growth on the uncrystallised element.

5. Small Pot Commutation — Up to £10,000 Per Pot

If you have small pension pots (each valued at £10,000 or less), you can commute them fully — 25% tax-free, 75% taxable — without triggering the MPAA and without the amount counting against your Lump Sum Allowance. You can commute up to 3 personal pension small pots in your lifetime.

Occupational pension small pots (up to £10,000 each) can also be commuted — there is no limit on the number of occupational small pots. The pot must genuinely be valued at £10,000 or less at the point of commutation. This is a useful strategy to clear old small pension pots without affecting your LSA or triggering the MPAA.

6. PCLS Timing — Year of Retirement Income Planning

The tax year in which you take your PCLS is also the year in which you begin taking (taxable) drawdown income. If you retire partway through a tax year, you may have employment income and pension income in the same year, potentially pushing you into a higher tax band for drawdown withdrawals.

Strategy: If you retire in, say, October, consider taking your PCLS immediately (tax-free — no issue), but delay the first drawdown withdrawal until the following April (new tax year). This means you have a full year with no employment income, allowing your full personal allowance and basic rate band to absorb drawdown income efficiently. Drawdown income is entirely flexible — you choose when to withdraw and how much.

7. Annuity vs Drawdown — The Post-PCLS Decision

After taking your PCLS, you must decide what to do with the remaining 75% drawdown fund. Your main options: (a) Flexi-access drawdown — remain invested, take variable income. Full investment risk and longevity risk on you. Maximum flexibility. (b) Lifetime annuity — convert the fund to a guaranteed income for life. No investment risk, no longevity risk. Very limited flexibility. (c) Combination — annuitise enough to cover essential expenses (alongside state pension and DB pension), keep the rest in drawdown for flexibility and inheritance.

Annuity rates in 2026 are significantly higher than in 2020–2022 (driven by higher long-term interest rates). A £100,000 fund might purchase ~£6,000–£7,500/year annuity for a healthy 65-year-old with no inflation protection. With inflation protection and spouse's pension, the rate is lower.

8. The PCLS and IHT Planning

Pension funds are currently outside your estate for Inheritance Tax purposes. This means a pension fund is not subject to the 40% IHT charge on death (unlike ISAs, cash, property, etc.). Spending your non-pension assets first and preserving the pension fund can therefore be an effective IHT strategy — the pension passes to beneficiaries outside the IHT calculation.

Important change from April 2027: The government has announced that unspent pension funds will be included in estates for IHT from April 2027. This significantly changes the IHT calculus for pension planning. Before this date, the strategy of using the PCLS for spending while keeping the uncrystallised fund as an IHT-exempt legacy pot remains highly effective. After April 2027, the balance shifts toward spending pension funds rather than non-pension assets.
