Steps to delete an employee from a payroll definition:
Go to Payroll
Click "Edit" on your Payroll Definition
Uncheck the employee from the list of employees
Click "Save"
Next time you run payroll, they will not show up on the list.
This is only removing the employee from the payroll. They will still show up in the list of employees and history. We don't recommend deleting an employee permanently as this would also remove them from reports and forms required for audits.
