Call centre. Administrative services for business operations. Internal office mail and messenger services. Data analysis services. Compulsory social security services. A contract for providing additional capacity and capability to HM Revenue and Customs to correct working tax credit claims that are potentially running with incorrect information.

The successful supplier will be required to contact HMRC's customers and by using HMRC's standard operating procedures, verify the customer's circumstances, either at the point of the renewal of the claim or during the period of the award.

HMRC will allocate information to the Contractor via a secure method of electronic transfer. The Contractor will assess the claim, apply their own analysis and using their own employees contact customers by mail, telephone and text messaging.

The Contractor will be responsible for receiving evidence from customers in a variety of formats, holding that evidence securely and accessing HMRC records to amend an award if required.

The Contractor will be responsible for returning all data on each case securely to HMRC irrespective of any correcting action undertaken. The Contractor must be in a position to operate a flexible approach to resourcing the requirement and the ability to meet all of HMRC's requirements for the security of taxpayer information.

The Contractor is required to make decisions regarding tax credits entitlement. Consequently the Commissioners for HM Revenue and Customs have exercised their powers under section 14 of the Commissioners for Revenue and Customs Act 2005 to delegate to the Contractor the specific functions needed to permit this.
