About the period of self-assessment of return

The deadline of online tax return in this year is 31 Oct 2022. The tax year is from 6 April 2022 to 5 April 2023. If I fill the online tax return on 31 Oct 2022, I do not know how much income I will receive from 1 Nov 2022 to 5 April 2023. What should I do? Thank you.

Hi,
 

The tax return that is due by 31/10/22 is for the year ended 5 April 2022 for which all your income details should now be held . Thank you.
