Pension Lump Sum Tax-Free UK 2026: How the 25% Rule Actually Works

What changed in April 2024 — and what stayed the same

For decades, the rule was simple: take up to 25% of your pension pot tax-free. The rule still exists — but from 6 April 2024, the mechanism changed fundamentally.

The Lifetime Allowance (LTA), which was £1,073,100 and triggered a tax charge if exceeded, was abolished. In its place came two new allowances:

• The Lump Sum Allowance (LSA): £268,275 — this caps the total tax-free cash you can take over your lifetime across all your pensions.
• The Lump Sum and Death Benefit Allowance (LSDBA): £1,073,100 — this caps the total tax-free amounts payable on death.

What changed: If you have a pension pot worth more than £1,073,100, you can no longer take 25% of the entire fund tax-free. You are limited to £268,275, regardless of pot size.

What stayed the same: For the vast majority of savers — those with pots below roughly £1.07 million — 25% of their pot remains less than £268,275, so the practical outcome is the same as before. The old rule and the new rule produce identical results for them.

The name also changed. What was informally called the "tax-free lump sum" or "tax-free cash" is now formally called the Pension Commencement Lump Sum (PCLS) when taken at the point of crystallising (accessing) your pension.

The Lump Sum Allowance: how it accumulates

Every time you take a tax-free lump sum from any pension, it reduces your remaining LSA. The allowance is lifetime and cumulative:

• Take £100,000 PCLS from Pension A in 2026 → LSA remaining: £168,275
• Take £168,275 PCLS from Pension B in 2030 → LSA exhausted
• Any further tax-free cash from Pension C → taxed as income at your marginal rate

This means sequencing your pension access matters. If you have multiple pension pots, the order in which you draw them affects whether you stay within the LSA across your lifetime.

Individuals who hold Enhanced Protection, Fixed Protection 2012, Fixed Protection 2014, Fixed Protection 2016, or Individual Protection from the previous Lifetime Allowance regime may have a higher LSA entitlement. These protections were frozen on 6 April 2024 but remain valid.

How to actually take your PCLS: drawdown vs annuity

Route 1: Flexi-access drawdown

This is the most flexible option and the most common route for savers who want to remain invested:

1. You designate your pension pot (or part of it) into a flexi-access drawdown arrangement.
2. At that point, you can take the PCLS — up to 25% of the crystallised fund or the remaining LSA, whichever is lower — as a tax-free lump sum.
3. The remaining 75% stays invested in your drawdown fund. You draw income from it as and when you choose, paying income tax at your marginal rate on each withdrawal.

Key feature: You do not have to take all your pensions at once. You can crystallise one pension, take its PCLS, and leave other pensions untouched for later — preserving LSA and keeping options open.

MPAA trigger: The moment you take any taxable income from the drawdown fund (not just the PCLS), the Money Purchase Annual Allowance is triggered. Future contributions to money purchase pensions are then capped at £10,000 per year. If you are still working and contributing, plan carefully.

Route 2: Annuity purchase

If you buy an annuity, you can take the PCLS immediately before (or as part of) the annuity purchase. The remaining 75% is used to buy the guaranteed income. Once an annuity is purchased, it cannot be undone — you have exchanged your pot for an income stream.

Annuities have become more attractive with higher interest rates. A 65-year-old with a £300,000 pot (after taking £75,000 PCLS) might secure around £15,000–£18,000 per year in 2026, depending on whether they want inflation linking and spouse's pension.

UFPLS: the alternative to taking a lump sum upfront

An Uncrystallised Funds Pension Lump Sum (UFPLS) is a different way to access your pension, without formally crystallising the whole fund first.

With a UFPLS:

• You take a withdrawal directly from your uncrystallised pension pot
• 25% of each payment is tax-free (up to the available LSA)
• 75% of each payment is taxed as income in the year received
• You do not need to set up a drawdown account first
• Each UFPLS triggers the MPAA

When UFPLS works better than upfront PCLS:

• You do not need all your tax-free cash immediately
• You want to spread taxable income across multiple tax years to stay in lower tax brackets
• You are in a phased retirement, winding down employment income gradually
• Your pension provider supports UFPLS withdrawals (not all do)

Example: Sandra has a £400,000 pension pot. Rather than taking £100,000 tax-free upfront and moving the rest into drawdown, she takes £20,000/year as UFPLS. Each payment is 25% tax-free (£5,000) and 75% taxable (£15,000). Over several years this gives her flexible access with manageable annual tax bills.

Note: The LSA still applies to UFPLS. The tax-free 25% portions of each UFPLS payment accumulate and count against your £268,275 lifetime cap.

Defined benefit (DB) pension lump sums: commutation explained

If you have a final salary or career average (DB) pension, the lump sum mechanics are different. Your scheme provides a guaranteed annual pension income. To get a lump sum, you give up ("commute") some of that annual pension.

The commutation factor is the key number — it tells you how many pounds of lump sum you receive per £1 of annual pension given up.

Is commuting worth it? It depends on your life expectancy and the factor. A factor of 20:1 means you need to live 20 years after retirement (not including investment returns on the lump sum) to break even in income terms. At 60 with average life expectancy to 85+, a 20:1 factor is broadly fair. A 12:1 factor is rarely good value — you are giving up a secure, index-linked income stream cheaply.

The lump sum received via commutation is tax-free up to the LSA (£268,275). Any commuted lump sum above this is taxed as income.

Important: Many DB schemes have a maximum commutation limit — often around 25% of the capital value of the pension (calculated using a standard factor). You cannot commute the entire pension to cash.

Worked example: £800,000 pension pot

Meet James, aged 63, who has accumulated an £800,000 defined contribution pension pot. He wants to understand exactly how much tax-free cash he can take.

The old assumption (pre-2024 thinking):

"I can take 25% = £200,000 tax-free."

The 2026 reality: James's 25% of £800,000 = £200,000. The LSA is £268,275.

Since £200,000 < £268,275, James's LSA is not a constraint here. He can take the full £200,000 tax-free.

He then moves the remaining £600,000 into drawdown, invested in a balanced fund.

Tax on drawdown income: James draws £30,000/year from the drawdown fund. His State Pension is £11,502/year. Total income: £41,502. After the personal allowance (£12,570), he pays:

• Basic rate (20%) on £37,700: £7,540
• Higher rate (40%) on £41,502 − £12,570 − £37,700 = … wait, £41,502 − £12,570 = £28,932 taxable income, all in the basic rate band.
• Income tax: £28,932 × 20% = £5,786/year

Now consider a larger pot — £1,200,000:

• 25% = £300,000 — but this exceeds the LSA of £268,275
• James can only take £268,275 tax-free
• The remaining £31,725 (£300,000 − £268,275) cannot be taken tax-free; if he takes it as a lump sum it is taxed as income
• Remaining in drawdown: £1,200,000 − £268,275 = £931,725

This is where the LSA cap bites. For a very large pot, the effective "tax-free percentage" falls below 25%.

Pensions and Inheritance Tax: the window that closes in April 2027

One of the most important planning points in 2026 is the IHT treatment of pension pots.

Current rules (until April 2027): Defined contribution pensions sit outside your estate for Inheritance Tax purposes. If you die with money left in your pension pot, it does not attract IHT and can be passed to beneficiaries (often tax-free if you die before 75, or as income tax on withdrawals if after 75). This makes pensions an excellent vehicle for passing wealth to the next generation.

Proposed change from April 2027: HMRC has legislated that unused DC pension funds will be brought into the IHT calculation from April 2027. Combined with the nil-rate band (£325,000) and residence nil-rate band (£175,000), this could make large pension pots subject to the 40% IHT charge on death.

Planning implications for 2026:

• Consider whether to draw down more of your pension before 2027 to use the tax-free cash while the IHT exemption still applies
• Weigh drawing pension income now (paying income tax) vs leaving it in the pension (potentially paying IHT + income tax on beneficiary withdrawals post-2027)
• Do not rush to draw everything — model the numbers carefully with a financial adviser

For estates already above the IHT threshold: The pension has been a powerful tool for passing wealth. This window is closing, and 2026/27 is likely the last full tax year to plan around the current rules.

Taking the lump sum: practical steps

1. Check your existing LSA usage. If you have already accessed any pension before April 2024, HMRC has a transitional calculation that converts the old LTA percentage used into an LSA figure. Most providers can confirm your remaining LSA.

2. Get a statement of your pension value. For DC pensions, your current fund value. For DB, get a statement of benefits showing the pension you have built up and the commutation options.

3. Choose your vehicle. Drawdown (flexible, requires ongoing management), annuity (guaranteed, irreversible), or UFPLS (flexible, simpler set-up). Most people with large pots use drawdown.

4. Instruct your pension provider. Complete the crystallisation paperwork or UFPLS withdrawal form. Your provider will deduct tax on the taxable portion (75%) at the emergency rate initially — you may need to reclaim via a P55/P53Z/P50Z form if you are not a regular taxpayer.

5. File your Self Assessment. Pension withdrawals are reportable income. Ensure they are included on your tax return.
