A cash ISA (Individual Savings Account) is a tax-free way to save. On other savings accounts, you may have to pay income tax on the interest you earn. The interest on a cash ISA is free from tax, so all the interest you earn, you keep. Take a look at our cash ISA rates below.
For the tax year starting 6 April 2018, the ISA allowance is £20,000 for cash or Stocks & Shares ISA and £4,260 for Junior ISAs.
