Lump Sum Allowance and LSDBA — the post-Lifetime-Allowance framework

The Lifetime Allowance — the cap on pension wealth that could be drawn tax-favourably — was abolished from 6 April 2024 and replaced by two separate allowances: the Lump Sum Allowance (LSA) and the Lump Sum and Death Benefit Allowance (LSDBA). The change was structural, the figures were less generous than a casual headline suggested, and the interactions with old-regime protections are intricate.

This is the practical version for someone wanting to understand the framework two years in.

What was abolished, what wasn’t

The old Lifetime Allowance was a single cap — most recently £1,073,100 — applied to your total pension wealth when you crystallised benefits, with a 25% extra charge (or 55% if taken as a lump) on anything above it.

The 25% lump sum tax charge above the LTA was abolished in April 2023, and the LTA itself was removed completely from April 2024. So:

• Investment growth above £1,073,100 in your pension: no longer a problem.
• Income drawn from above that figure: just taxed as normal income at marginal rate, no LTA charge.
• The 25% tax-free element of pension withdrawals: now subject to the new LSA cap.

The headline impact was much more modest than the “abolition” framing suggested, because the 25% tax-free portion — the thing most people actually cared about — got a new, separate cap.

The Lump Sum Allowance (LSA)

The LSA caps the total tax-free lump sums you can take from your pensions over your lifetime.

• Standard LSA: £268,275.
• That figure is exactly 25% of the old £1,073,100 LTA, by design.

Each time you take a tax-free lump from a pension, the amount uses up your LSA. Once your LSA is fully used, further tax-free lump sums aren’t available — additional withdrawals are entirely taxed as income at your marginal rate.

So if your pension pot is large enough to support a £268,275+ tax-free lump (which means a pot of roughly £1,073,100 or more), you’d cap out at the LSA and any further tax-free lump capacity from a second pot is gone.

The 25% rule itself still applies per pot up to the LSA. If you have a £400,000 pot and want to take the maximum tax-free, that’s £100,000 — well within the LSA limit, so all £100,000 is tax-free. If you later take £200,000 tax-free from a £800,000 pot, you’ve used £300,000 of LSA capacity — but you only had £268,275, so the last £31,725 is taxable.

In practice, most people don’t hit the LSA. The cohort affected is those with pension wealth above ~£1.07 million who’d planned to take the full 25% as a single lump.

The Lump Sum and Death Benefit Allowance (LSDBA)

The LSDBA covers tax-free lump sums taken in life plus tax-free lump sums paid to beneficiaries on death.

• Standard LSDBA: £1,073,100 (same as the old LTA figure).

This is the broader cap. It includes:

• Tax-free lump sums you took in life (which also count against the LSA).
• Lump sums paid out as serious-ill-health lump sums.
• Tax-free death benefit lump sums paid to beneficiaries if you die before age 75.

If your total tax-free in-life lumps plus tax-free death benefits exceeds the LSDBA, the excess is taxed at the recipient’s marginal income tax rate (for death benefits) or your marginal rate (for in-life withdrawals).

For most people the LSDBA is the more material cap — it determines how much of a pension can pass tax-free to family on death. With pensions about to come into the IHT framework from April 2027, the LSDBA story will become entangled with IHT rules.

How old-regime protections carry over

People who had LTA protections under the old regime — Fixed Protection 2012, 2014, 2016, Individual Protection 2014, 2016, etc. — get correspondingly higher LSA and LSDBA figures.

For example:

• Fixed Protection 2012 (protected LTA of £1.8m): LSA of £450,000 and LSDBA of £1,800,000.
• Fixed Protection 2014 (protected LTA of £1.5m): LSA of £375,000 and LSDBA of £1,500,000.
• Fixed Protection 2016 (protected LTA of £1.25m): LSA of £312,500 and LSDBA of £1,250,000.
• Individual Protection 2014/2016: LSA = 25% of personalised LTA, LSDBA = personalised LTA.

The protections continue to apply automatically — you don’t need to reapply. But the rules around when protection is lost (active contributions after the protection date being the main one) continue to operate, so it’s still worth understanding what your protection conditions are.

Transitional rules for benefits taken before April 2024

Anyone who’d already crystallised pension benefits before April 2024 has a transitional position. Your remaining LSA and LSDBA aren’t the full figures — they’re reduced by what you’ve already used under the old LTA system.

Two routes:

1. Standard transitional reduction. HMRC applies a default formula based on percentages of LTA used, reducing your remaining LSA / LSDBA by that amount.
2. Transitional Tax-Free Amount Certificate (TTFAC). You can apply for HMRC to recalculate based on the actual tax-free amounts you took rather than the default assumption. Worth doing if you took less than the maximum tax-free in past crystallisations — the default formula can over-state your usage.

The certificate route is administratively heavy and usually only worth pursuing for individuals with substantial residual pension wealth where the difference between standard and actual usage is material. HMRC’s pensions tax manual covers the mechanics.

The 25% rule, restated

In practice, for someone with a pension pot below ~£1m, the headline rule is unchanged: you can take 25% of each pot tax-free, with the other 75% taxable as income.

For someone with a pot between £1m and £1.07m, the same rule applies for now but the LSA could bite at the margins as the pot grows.

For someone with a pot above £1.07m, you can’t take 25% of the whole pot tax-free — only £268,275, regardless of pot size (absent protection).

For someone with substantial protections, your effective “25%” cap is higher.

How it interacts with the from-April-2027 IHT change

From April 2027, unused pension pots will be brought into the IHT framework. The detail matters because:

• The pension pot value will form part of the deceased’s estate for IHT purposes.
• Beneficiary income tax on pension drawdowns post-death continues to apply on top.
• The interaction between IHT, the LSDBA cap and the income tax treatment for beneficiaries is complex and shifts the planning calculation significantly.

For high-net-worth retirees with substantial pension wealth, this is a planning event worth engaging with an adviser on before April 2027. See our pensions IHT April 2027 guide for the detail.

What this means in practice for most people

If your total pension wealth is under £1.07 million and you don’t expect to cross it in the next decade or so, the LSA and LSDBA framework largely doesn’t affect you. The 25% tax-free lump rule applies as it always did.

If you’re close to or above £1m of pension wealth — which includes a much larger group than people realise once defined benefit transfers and decades of compounding are added in — the LSA / LSDBA caps are real and warrant planning attention. Specifically:

1. Check whether you have any LTA protection in place from previous tax years and what conditions attach to it.
2. Get a current valuation of all your pensions — DB pensions valued at the relevant multiple (typically 20× the annual pension), DC pensions at current market value.
3. Model the tax position under different withdrawal strategies — particularly the trade-off between taking the maximum tax-free now (locks in your LSA use) vs leaving it for later (gives flexibility but exposes growth to the cap).
4. Consider whether you have spare annual or carry-forward allowance for the next few years before the IHT changes start to bite.

A few specific situations to watch

• DB and DC together. If you have a defined benefit pension that converts to a tax-free lump sum on crystallisation (the “commutation lump sum”) plus DC pots, the DB lump uses LSA just like a DC tax-free withdrawal does. Combined plans can hit the cap unexpectedly.
• Public sector schemes. NHS, civil service, teachers’ and police pensions all have specific commutation rules and interact with the LSA in scheme-specific ways. The scheme administrator should provide you with calculations specific to your benefits.
• Active scheme contributions while on Fixed Protection. Adding contributions to any registered pension scheme after the relevant protection date breaks Fixed Protection. Check what your current employer pension arrangements are doing before joining a new scheme.
• Pension recycling rules. Taking a tax-free lump sum and then significantly increasing pension contributions can trigger anti-avoidance rules. Worth knowing before any large lump.

The bigger picture

The LTA-abolition-with-an-LSA-replacement-cap is the kind of policy change that’s easy to misread. The headline made it sound like an unlimited tax-free shelter; the reality is a £268,275 lump cap on top of the normal income tax on drawn pension income. For everyone except the genuinely wealthy, the change is largely cosmetic. For people approaching or above £1m in pension wealth, the new framework — and its imminent intersection with IHT from April 2027 — is one of the most consequential planning areas in UK personal finance right now.
