Do I need to reverse the payment made in week 1 as I didn't change the tax code to 0T and the week number? If so this then makes the nett payment a negative amount and Sage 50 payroll will not process a negative amount so I'm stuck as to what to do?
An employee left on 31/03/23 so I processed the P45 with that as the leaver date but as we pay a week in hand they did did not receive their final pay until 07/04/23 after they had left. So now this doesn't reflect in the final figure in the P45 and they say they want it changing. They left in week 52 and were paid in week 1 so I'm not sure what to do now.
I am self employed and employed. My self employment earns me about £1500 each year and I have minimal expenses. I have never heard of the £1000 trading allowance until today. I think this sounds like it would be better for me to use instead of deducting expenses? Can I amend previous tax returns to include this do you know?
