Capgemini lands £37 million SAP migration deal, extending HMRC partnership to 28 years
HM Revenue & Customs awarded Capgemini a £37 million contract to move its tax platform from SAP ECC to S/4HANA, potentially lengthening the supplier relationship to 28 years.
HM Revenue & Customs announced a £37 million contract for Capgemini to migrate its Enterprise Tax Management Platform from SAP ECC 6.0 to the newer S/4HANA suite, a migration that will support 40,000 users handling over £800 billion of tax revenue each year. The agreement, which runs to 2032, could extend Capgemini’s involvement with HMRC to a total of 28 years, dating back to the 2004 Aspire contract. HMRC officials emphasized that the tender process was fair, with bidders sourced from the Digital & Legacy Application Services framework, which includes Accenture, Atos, CGI, Cognizant and IBM.
In parallel, Capgemini holds a five-year run-and-change contract for the same platform, valued between £403 million and £574 million, and a separate contact-centre services deal worth up to £600 million. The procurement follows a 2025 £275 million SAP sovereign-cloud award and reflects ongoing scrutiny of past Aspire spending, which the National Audit Office said was significantly higher than originally estimated.
Why it matters
The deal shapes how the UK collects and processes billions in tax, affecting services for millions of taxpayers.
