Your remaining ISA balance is displayed at the top of your Dashboard on the right-hand side.
When you are topping up your ISA portfolios, you will also see the remaining ISA allowance to see how much you can still add this year.
Please note that the remaining ISA allowance shown only considers contributions made to InvestEngine. If you have another ISA account with a different provider, you will need to keep track of your overall allowance yourself.
