If you’d like to make a payment to your ISA allowance for 2023/24, you’ll need to send this from your nominated account no later than 3pm on 5 April, 2024.
Payments made after this time will be counted toward your 2024/25 allowance.
This does not apply to ISA transfers. They’ve already been counted for your allowance this year, so even if we receive the transferred funds after the deadline, they’ll still count toward your 2023/24 allowance.
