— Understanding the result
The Lump Sum and Death Benefit Allowance (LSDBA) caps the total tax-free lump sums payable across your lifetime and on death — £1,073,100 as standard. Pension commencement lump sums consume both the LSA and the LSDBA; serious ill-health lump sums and tax-free death benefits before age 75 consume the LSDBA only. For an individual receiving it in their own right, an amount above the remaining allowance is taxed as their pension income at their marginal rate.
— How it's calculated
The Lump Sum and Death Benefit Allowance
The LSDBA caps the total tax-free lump sums payable across the member's lifetime AND on death — £1,073,100 as standard. Every PCLS consumes both the LSA and the LSDBA; serious ill-health lump sums and tax-free death benefits (death before 75) consume the LSDBA only. For an individual receiving it in their own right, an amount above the remaining allowance is taxed as their pension income at their marginal rate.
Pre-75 vs post-75
The allowance test applies to serious ill-health lump sums and death benefits only where the event is before age 75. After death at 75 or over, no allowance is used and no excess arises: a taxable lump sum death benefit is pension income of an individual receiving it in their own right, while for a non-qualifying recipient the scheme administrator pays the 45% special lump sum death benefits charge instead. PCLS and UFPLS keep consuming allowance after 75.

Who is taxed on the excess — and the 45% non-qualifying-person charge
An excess over the remaining LSDBA on a lump sum death benefit paid within the two-year window after a death before 75 is pension income of the recipient, whoever the recipient is (ITEPA 2003 ss.637H–637M). For an individual it is taxed at their own marginal rate, not the deceased member's, so the tool takes their other income as an input. The 45% special lump sum death benefits charge, paid by the scheme administrator, applies instead only where a taxable lump sum death benefit goes to a non-qualifying person (a company, or an individual acting as a trustee other than a bare trustee, a personal representative, a director, a partner or an LLP member) after death at 75 or over or, for most types, when paid after the two-year window following a death before 75. Paid late to a qualifying individual, the whole lump sum is their pension income even though death was before 75.

Protection raises the ceiling
Fixed protection preserves a former lifetime-allowance ceiling as a higher LSDBA: FP2012 £1,800,000, FP2014 £1,500,000, FP2016 £1,250,000 — fixed nominal amounts that do not index. Individual Protection 2014 and 2016 set the LSDBA to the member's protected LTA (up to £1.5m for IP2014, £1.25m for IP2016). Primary Protection gives £1,800,000 uplifted by the certificate's enhancement factor. When the tax-free maximum of a pension commencement lump sum is tested, though, part of the Primary Protection rules is set aside, and which allowance then applies has not been settled for this tool, so the full workflow calculates such a lump sum only while it is no more than the standard £1,073,100 less the lump sum and death benefit allowance already used. Enhanced Protection gives an LSDBA equal to the value of the member's uncrystallised rights on 5 April 2024 (FA 2024 Sch 9 para 126(1)(c)) — a finite, member-specific figure, not an uncapped allowance. The tool above covers fixed protection 2012, 2014 and 2016 and individual protection 2014 and 2016. For Primary Protection, use the full workflow: it asks for the certificate’s protected lifetime allowance and enhancement factor, calculates serious ill-health lump sums and lump sum death benefits, calculates a pension commencement lump sum only within the limit above, and does not calculate an uncrystallised funds pension lump sum. It stops, rather than estimate, where it cannot count the member's benefits taken before 6 April 2024, for example when lump sum protection is also registered. The full workflow does not calculate any lump sum for a member with Enhanced Protection: work those out outside ParaplanAI.

— How to calculate the remaining lump sum and death benefit allowance
Step 1
Start from the standard LSDBA
Take the standard Lump Sum and Death Benefit Allowance of £1,073,100, or the higher amount if a protection applies.
Step 2
Deduct allowance already used
Subtract the LSDBA used at earlier events — including pension commencement lump sums, which consume the LSDBA as well as the LSA.
Step 3
Apply the current event
Reduce the remaining allowance by the lump sum at this event — a PCLS, a serious ill-health lump sum, or a tax-free death benefit before age 75 — capped at the allowance remaining.
Step 4
Read the remaining allowance
What is left is the lump sum and death benefit allowance still available.
Step 5
Tax any excess
For an individual recipient, any amount above the remaining allowance is taxed as their pension income at their marginal rate.
— Worked example
- Applicable LSDBA
- £1,073,100.00
- Consumed by this event (capped at remaining)
- £1,073,100.00
- Remaining
- £0.00
- Excess — taxed on the beneficiary at marginal rate
- £126,900.00
- Estimated tax on the excess (beneficiary’s other gross income £30,000)
- £53,322.00
Computed live by the same engine the tool above runs. The excess is taxed as the beneficiary's income at their marginal rate — this estimate prices it on the beneficiary's own income, not the deceased's. The 55% and 25% lifetime allowance charges were removed a year before the allowance itself: they went on 6 April 2023 (F(No.2)A 2023), and the Lifetime Allowance was abolished on 6 April 2024 when the LSDBA replaced it.
— Frequently asked questions
What is the Lump Sum and Death Benefit Allowance?
The LSDBA caps the total tax-free lump sums payable across a member’s lifetime and on death — £1,073,100 as standard. It has applied since the Lifetime Allowance was abolished on 6 April 2024.
What consumes the LSDBA?
Every pension commencement lump sum consumes both the LSA and the LSDBA. Serious ill-health lump sums and tax-free death benefits paid before age 75 consume the LSDBA only.
How are death benefits taxed after age 75?
After death at 75 or over, no allowance is used and no LSDBA excess arises. A taxable lump sum death benefit is pension income for an individual receiving it in their own right; for a non-qualifying recipient the scheme administrator pays the 45% special lump sum death benefits charge instead. The allowance test applies only where the event is before 75.
How is an LSDBA excess taxed?
Where a lump sum death benefit is paid within the two-year window after a death before 75, the amount above the remaining allowance is the recipient’s pension income, taxed for an individual at their own marginal rate, not the deceased member’s (ITEPA 2003 ss.637J(2), 637S). That applies even to a non-qualifying recipient. The 45% special charge (FA 2004 s.206) applies only where a non-qualifying recipient is paid after death at 75 or over or, for most types, outside the two-year window. The old 55% and 25% lifetime allowance charges had already gone from 6 April 2023 (F(No.2)A 2023), a year before the allowance itself was abolished on 6 April 2024.
Does protection raise the LSDBA?
Yes. Fixed protection preserves a former lifetime-allowance ceiling as a higher LSDBA — FP2012 £1,800,000, FP2014 £1,500,000, FP2016 £1,250,000 — as fixed nominal amounts with no indexation. Individual Protection 2014 and 2016 set it to the member’s protected Lifetime Allowance (up to £1.5m and £1.25m respectively). Primary Protection gives £1,800,000 uplifted by the certificate’s enhancement factor. When the tax-free maximum of a pension commencement lump sum is tested, though, part of the Primary Protection rules is set aside, and which allowance then applies has not been settled for this tool, so the full workflow calculates such a lump sum only while it is no more than the standard £1,073,100 less the lump sum and death benefit allowance already used. Enhanced Protection sets the LSDBA to the value of the member’s uncrystallised rights on 5 April 2024 (FA 2024 Sch 9 para 126(1)(c)) — a finite, member-specific figure.
