“…for me pension is a better bet as you get a 20%/40% uplift straight away”
Balanced against not being able to access any of it until you’re 55, and apart from pulling out 25% tax-free you’ll be paying 20%/40%/whatever-the-rate-is-by-then on the rest of it.
An ISA doesn’t get the tax relief, but OTOH it doesn’t get taxed when you take the money out.
This is the quandry I’m grappling with at the moment, and for now I’m coming down in favour of building a suite of ISAs.
LISAs might be worth a look for some people. They seem to be a pilot for when the government stops giving tax relief on pension contributions.
That’s why I said “depends on age and future need for cash” which you conveniently didn’t quote !
Either way, it’s about balance and not using at least in a small proportion the fiscal benefit of pension (while it’s there) is very naive particularly vs ISA. If the OP is in his 40s then it’s financial suicide.
As someone said, you can draw down up to the allowance tax free. So you gained up to 40% to start with, capitalised and now zero tax on the first (currently) £11k. Sounds good to me.
