But you can pay up to £20,000 during the 2024/25 tax year.
Additionally, with HSBC, you can make a lump sum deposit of £20,000 or pay smaller amounts regularly. The latter allows low-budget individuals to make smaller contributions in a cash ISA without worrying about limited funds.
Saving with an HSBC cash ISA is an excellent idea since this service provider offers competitive rates. The standard rate is 2.50% AER/tax-free. However, the numbers range from 2.85% AER/ 2.81% tax-free to 3.20% AER/ 3.15% tax-free for HSBC Premier Loyalty ISA and Other Current Accounts, respectively.
