HM Revenue & Customs has awarded Capgemini a £37 million contract to migrate its Enterprise Tax Management Platform (ETMP) from the legacy SAP ECC 6.0 system to SAP's S/4HANA platform. The deal, running until 2032, could extend Capgemini's relationship with the UK tax authority to 28 years, dating back to when it became HMRC's lead technology supplier in 2004 under the Aspire contract. HMRC has stressed that the procurement process was fair and competitive, amid scrutiny over the firm's long-standing dominance as a supplier.

ETMP handles more than £800 billion in tax revenue and payments annually for around 40,000 users, covering returns processing, tax accounting and data management. Bidders for the new contract came from the Digital & Legacy Application Services framework, which also includes Accenture, Atos, CGI, Cognizant and IBM, with ethical walls put in place to prevent conflicts of interest. Capgemini has secured a string of related HMRC deals in recent years, including a £51 million ETMP contract in 2022, a five-year agreement worth up to £574 million in 2024, and a Contact Centre as a Service deal worth up to £600 million; separately, HMRC awarded SAP a £275 million uncompeted contract in January for S/4HANA sovereign cloud capability.
