Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, how many amendments to tax credit awards Concentrix have made due to error on behalf of (a) Concentrix and (b) since the beginning of the contract between Concentrix and HM Revenue and Customs.

This information is not held in the form requested. An amended award could be due to a number or reasons and without retrospectively looking at each award individually, HM Revenue and Customs would not be able to identify how many amendments were made in error. Undertaking an assurance exercise of this size could only be done at disproportionate cost.
