What is a cash ISA?

A cash ISA generally allows UK residents aged 18 or over to save up to their annual ISA allowance tax-free each tax year. However, if you are 16 or 17 and your fixed rate ISA is maturing, you can reinvest this into a new Fixed Rate Cash ISA. The allowance is £20,000 for 2025/26. With other savings accounts, you may have to pay tax on the interest you earn, depending on your Personal Savings Allowance. The interest on a cash ISA is tax-free, so all the interest you earn, you keep.
