Maxing out ISA allowance

[Bushkin]

Does anyone know if there’s stats for how common it is for people to use all their ISA allowance?

Was discussing with DH earlier and can’t find anything

I have not searched for any stats but with the average wage being just under £30k, I would guess the average person cannot put £20k into an ISA.
What I do know though is that the annual Capital Gains Tax allowance is one of the most unused allowances that exists.

I’d assume low. However, my jaw dropped when my loaded mate casually dropped into conversation that she was ‘just’ using her annual ISA allowance to play around on stocks and shares 😂 Oh how the other half live.

The pdf on there holds a lot of statistics - I think you will need to combine more than one stat to find out the exact answer you're looking for though - maybe chart 1 and chart 7 and the adult population at first glance.

As a very rough estimate ... assuming adult population is 50M, then 20% of adults subscribed to an ISA in the tax year 17-18 (10M), of which 20% were maxed out - so 4%? I may have got that very wrong though so definitely look at it yourself!
