If an employee leaves and you've accidentally processed pay for them in one or more subsequent pay periods, don't worry, you can correct your payroll by following the steps below.

 NOTE: If the issue occurred in a previous tax year, submit an adjustment to HMRC for a previous tax year. 

1. Rollback any periods that you processed in error for this employee.
    TIP: For help with doing this, follow the how to use the rollback option article. 
2. Check the payments for the year are correct for this employee, as your software uses these to create the P45.
3. Mark the employee as a leaver and produce their P45.
4. Now that you've got the P45 with the correct values, double-click the employee then click the Employment tab.
5. Take note of the leave date, then remove it.
6. Change the employee's tax code to 0T W1/M1.
7. Click Save then click Close.
8. Click Change Process Date and enter the process date for the last period you processed in error.
9. Select the relevant employee only on your employee list.
10. Click Enter Payments then enter £0.00 gross pay.
11. Ensure the net pay is £0.00.
12. Click Save/Next, then Close.
13. Update records for this employee.
14. Double-click the employee then click the Employment tab.
15. Enter the original leave date then click Save then click Close.

If you submitted a Full Payment Submission (FPS) with incorrect values for the employee who has left, submit an FPS adjustment. If you haven't sent any FPS, proceed with your payroll as usual and Submit the FPS.

Issue the P45 you printed at Step 2 to the employee, as this has the correct values.
