file income for april

Lets say the payment date for salary in April 2023 is on the 30th April 2023, should I file the payment of the 5 days (1-5 April) to tax year 2022-2023 or file the payment of the whole month of April to the tax year 2023-2024?

Hi
You would declare it in 23-24.

HI if i declare the salary of april in 23-24, then what is the meaning to the have the cut of day 5th april in every tax year?

Hi MJ K,
Assuming you are paid monthly, then all your April salary falls into the new tax year 23/24 and is not apportioned.
Some people are paid weekly and as such may receive a paytment prior to 5 April the last day of the tax year for 22/23. 
Tax months also run from the 6 of the month to the following 5 of the month for example.
Tax month 01- 6 April - 5 May 
Tax month 02 - 6 May - 5 June. 
Thank you.
