Before calculating the SMP please make sure that the employee's average weekly earnings are greater than £111.
Also your employee must have worked for you for 26 weeks going into the qualifying week (i.e. you must have processed pay in Payroll for this employee for the previous 26 weeks).
Head to Employees > Statutory Payments and select the relevant Employee from the drop down list.
Enter the baby due date.
Enter the MPP (Maternity Pay Period) for the employee and click Save.
The SMP information will be updated. The employee's AWE (average weekly earnings) will automatically be calculated based on the baby due date you entered.
The entry will be updated in the Statutory Payment Report under Employees > Statutory Payments. You can edit or delete the entry any time.
When processing payroll for the employee the basic pay field will be clear and the SMP field is updated automatically.
