Savings interest declared at end of tax yr but paid in next tax yr

I have a fixed term savings bond on which interest is payable in cash annually on 5 April but the first interest payment was actually received on 8 April 2024. In which tax year should this interest be declared under self assessment?

Hi,

The amount is based on the period to 05 April 2024 so you will include this in the 2023 to 2024 year.

Thank you.
