Amount to declare interest/dividend for Apr 2024

Hi, I am completing a self-assessment for year 2023/24. It's my first time to complete the form, and I would like to confirm say, if Bank A only sent me the interest payment on 25th of each month (and i did not receive any further doc from Bank A for tax reporting purpose), then do i need to declare the interest for April 24 (which was only received until 25 April 24) for year 2023/24? If so, do i need to report it in full or apportion it by myself as to include the interest for 1-5 April 24. Thank you!

Hi,
If you do not know or are not notified of the correct amount of bank interest to enter in your return, please ask your banks and building societies to confirm the correct figure for you.
Thank you.
