Thanks. I've been offered redundancy, and although I'm not sure of the exact formula used by the (DC) pension provider, by using formulas I've seen elsewhere, it seems my employer may have included PILON onto my final salary redundancy figures when forwarding to the pension provider. This has resulted in my current value tax-free amount being recorded higher than it should be.
If when I turn 50 I can withdraw tax-free 25% of whatever the value of the pension is on that particular future date anyway, then I assume it's in my best interest for this amount to actually be recorded as low as possible now in order to reduce my redundancy taxable amount through the SCSB calculations.
