RE: Pension v ISA after retirement29 May 2026 08:43
Rotherby, I think you’re slightly wrong in proposing taking from the drawdown and transferring the post tax funds into an ISA as you are not allowing for the investment gain you accrue in your SIPP from the income tax.
eg.
You withdraw £100 from your SIPP, pay £20 in tax, put £80 in an ISA and it grows,say 50%, and you end up with £120.
Or you leave the £100 in the SIPP and it grows 50% to £150, then you withdraw it , pay tax at 20% ( ie £30 ) and still end up with £120.
It seems to me that the only advantage of drip feeding into your ISA in retirement is that you can pass on the whole of your ISA to your surviving spouse as an ISA tax wrapper rather than just cash and that might be useful in some circumstances
