There are maximum amounts that you or your beneficiaries can receive as tax-free lump sums from your pension. These maximums apply to all your pensions, not just the M&S Scheme.
You can normally choose to exchange up to 25% of your pension for a tax-free cash lump sum. The LSA limits the amount you can exchange in this way to £268,275, which is 25% of the old Lifetime Allowance limit.
In addition, some lump sums paid to you in cases of serious ill health, or to others in the case of your death, can also be tax-free. The LSDB limits the total amount of tax-free lump sums that can be paid out to £1,073,100. Any lump sums you have taken that are included in the LSA, plus any serious ill health or death benefit lump sums, count towards this limit.
Both these limits replace the Lifetime Allowance which was abolished in 2024.
