What's the difference between a cash ISA and a stocks and shares ISA?

Reply

A cash ISA holds cash deposits with a bank or building society, earning interest tax-free. A stocks and shares ISA holds investments such as equities, bonds and funds, where returns are tax-free but the value can fall. The annual allowance is £20,000 for 2026/27 and you can split it across both types.
