CCM8140 - Closing the Examination: Informing the Customer - Overpayment
In the majority of examinations the revised award will not lead to an in-year recovery of overpaid credits. This is because most potential overpayments will be reviewed following the Section 17 end of year declaration and only the net amount overpaid at the end of the year will be recovered. The special circumstances in which an overpayment can be recovered in-year are described at CCM8125.
Where you are aware that the overpayment will be or is likely to be recoverable in-year you should advise the customer as soon as possible even if you are not yet in a position to revise the award. In addition, advise them that the overpayment will be repayable 30 days after the date of the revised award notice,
Where the figure includes an adjustment for an earlier year it will lead to an overpayment and you will need to explain to the customer how this will be recovered - see CCM8180.
