I have done my year end and i am now processing month 1 wages, our pay period is 1st to 31st March, pay date (processing date) is 14th April.

I have a couple of leavers in March, do i put the actual date they left (which is technically in the previous tax year) or should i use my processing date?

I'm just concerned of the confusion this may cause if the leaving date is in the previous tax year, but the P45 is for the new tax year.
