Cash ISAs - How do they work?

Why save with a Cash ISA?
  • You don't pay tax on any interest you earn but remember you can only pay into (subscribe to) one Cash ISA in any tax year. 
  • The government sets a limit on how much you can subscribe in every tax year (from 6 April to 5 April in the following year).
  • The overall ISA allowance for the 2017/18 tax year which commences on 6 April 2016 will be £20,000. Subscriptions can be split into any proportion between a cash ISA, stocks and shares ISA and an innovative finance ISA  up to the overall ISA allowance limit of £20,000.

Some other need to knows

  • If you have paid into a cash ISA, stocks and shares or innovative finance ISA since 6 April 2017, you will not be able to open a further ISA of the same type before 6 April 2018. 
  • You may however make additional payments - up to the ISA subscription limit of £20,000  for the 2017/2018 tax year - into your existing account(s), or by transferring those account(s) to another provider that will allow additional amounts to be added
  • Tax reliefs referred to are those applying under current legislation which may change. The favourable tax treatment for ISAs may not be maintained. The availability and value of the reliefs will depend on your individual circumstances.
  • If you already have an Ulster Bank Cash ISA and haven’t paid money in for a whole tax year you’ll need to complete a re-activation form (PDF) before you can pay money in again. Please take your completed form to your local branch.
