What is an Additional Subscription Form?
An Additional Subscription form should be completed if you are looking to add cash/stock to your Investment ISA account, but did not add anything in the previous tax year.
You can avoid filling out and sending this form to us by logging into your ISA account online, and adding cash via the 'cash manager' section. There you will be asked to accept the Declaration of Authority, which negates the need for you to send in a form.
Please note there is a different for when subscribing to a Corporate ISA.
