6.1.3.1 — The steps required to calculate an overpayment are as follows:
- establish the dates of effect to be used
i.e. the commencement date, the cessation date and any other variation dates - identify the "off" and "on" rates
i.e. what was paid, what should have been paid - calculate the amount overpaid
i.e. the difference between the "off" and "on" rates over the period of the overpayment - prepare a summary sheet.
