Top Cash Isas 2025/2025. Anyone looking for a low risk isa option, should consider a cash isa. That said, now might be a good time to see if you're getting a decent rate on your savings regardless.
But, under current rules, 16 and 17 year olds can open cash isas and save up to £20,000 tax free as well, in effect providing them with a £29,000 tax free isa allowance. The allowance can be split between different isa accounts, including a cash isa, stocks and shares isa, lifetime isa (up to £4,000 per year) and innovative finance isa.
