HMRC is welcoming proposals for its $670MN (£500MN) CCaaS megacontract.
The UK tax authority wishes to replace its legacy systems with a comprehensive omnichannel solution.
Alongside the core product, it hopes the budget will cover the future acquisition and development of add-on solutions.
Additionally, the money should cover additional services. These include service design, implementation, configuration, run & support, and ongoing optimization services.
The contract will span eight years from 19 December 2025 to 16 December 2033. However, HMRC wishes to add a possible one- or two-year contract extensions.
The process has moved swiftly since the tender details were disclosed on 27 May 2025.
Now, prospective CCaaS providers may request to participate in the tender. The deadline for doing so is June 23, 2025, at 11:59pm (GMT).
How the Tender Process Works
In UK Government tendering processes, an Invitation to Tender (ITT) or Request for Proposal (RFP) is typically issued.
The buyer - HMRC in this case - publicly advertises the opportunity and provides a detailed document outlining the project, which represents the current stage of this tender.
Next, potential suppliers submit proposals in response to the ITT/RFP, detailing pricing, technical specifications, timelines, and other relevant information.
Following submission, HMRC conducts an evaluation based on the predefined criteria in the ITT/RFP.
The final stage involves selecting the winning bidder and formalizing the agreement through a contract award.
Possible Front Runners for the CCaaS Megadeal
While all are welcome to join a bid, multiple vendors are considered front-runners for the contract.
