I'm not sure really - as I'm still finding the options a bit confusing ..(..and the assistance from the pension pot holder ( L&G) is pretty minimal )
.... but what I was thinking was ' crystallising ' a lump ( let's say £40k) - taking the 25% tax free in one go ( £10k) .....and having the remaining £30k draw down over 3 years paid out monthly .
This would still leave me with around £160k in the uncrystallised Fund (hopefully

) growing at around 10% per annum .
Questions I have are :-
1. Would I pay any income tax on the 75% crystallised ( £30k) ( assuming no other income). I presume not as the drawdown would only pay it out to me at around £10k per annum and I'd be taxed on receipt ?
2. Once the £40 k drawdown has been allocated - does the taxable portion ( the £30k) still sit in the fund as Investment and hence still grow ?
I guess if you're still working (?) and paying income tax ( and intend to Continue That way for a while ) ?
In which case it wouldn't really matter whether you did it in March or April.
If you're stopping work soon then you may want to push into April to minimise income tax for this year .
When you say " gonna take the whole lot out " ... there may be tax penalties for you that way - you may want to spread it out over a few years ( depending on how much it is )
