  • Individual Savings Accounts (ISAs) were introduced in 1999 to replace old-style tax free savings. They allow you to invest up to a set allowance each tax year (6 April to 5 April) on which you will pay no tax on any interest you earn. The current allowance is shown below.

  • You do not have to pay income tax on the interest paid in each of the years that you have your ISA provided all the ISA terms and conditions have been followed.
  • For a period of 30 days after opening your ISA, you may instruct us that you have changed your mind and we will return your deposit to you, subject to cheque clearance, with any accrued interest (tax will not be deducted).
