Why do I have to declare my ISA?

Her Majesty's Revenue and Customs (HMRC) ISA rules require you to make a declaration, when applying to open an ISA. This is to confirm that you are eligible to subscribe to your ISA.

If you haven't subscribed to your ISA for a whole tax year, then you need to declare your eligibility again and confirm that you haven't paid into another ISA of the same type in the current tax year. You will not be able to make any further deposits into your ISA until a new declaration is made.

If you have Triodos Internet Banking, you can complete a new declaration online. To do this, please log in to Internet Banking and go back to old Internet Banking via the green ‘Go to old Internet Banking’ button. Select 'Account Management, ISA Declaration Management', from the menu.

Alternatively you can download, print and complete a declaration form below, or you can contact us and we can post a declaration form to you.

Junior ISAs and Fixed Rate Cash ISAs do not need a new declaration to be made after the account is opened.
