The value of the contract for the 3-year term is £61,250,958 exc VAT. The total contract value including the optional 6-month extension is £71,500,000 exc VAT (the optional extension is subject to further governance and approval).

As negotiations commenced prior to 24 February 2025 and the coming into force of The Procurement Act 2023 they are governed by The Public Contracts Regulations 2015.

HMRC has awarded a 3-year contract to Fujitsu Services Ltd to provide hosting and associated services for the CESA application utilising Fujitsu's proprietary Modern VME Environment. The CESA application administers the collection of Income Tax for all taxpayers under Self-Assessment.

As CESA is Critical National Infrastructure (CNI), HMRC requires the secure and uninterrupted delivery of support to the application and considers the award of the new contract to be the only option for ensuring delivery of CESA until the migration to new arrangements. A programme has been set up to migrate the CESA application before this contract expires.
