HMRC's Salesforce deal: what could change for taxpayers

HMRC has chosen Salesforce to replace the systems its staff use to record and manage contact with taxpayers, in a contract worth up to £2 billion excluding VAT. The aim is one view of each customer, faster answers and more AI-assisted triage. No go-live dates have been published, so nothing changes for taxpayers or agents yet.

What has HMRC agreed with Salesforce?

HMRC has appointed Salesforce as its strategic Enterprise Customer Relationship Management (CRM) provider. Salesforce announced the deal on 15 October 2026, the day HMRC published the contract details notice. The Salesforce press release calls it a 15-year agreement worth up to £2 billion.

The dates and VAT-inclusive value come from the published notice as reported by The Stack and other trade press. The figure is a ceiling, not a guaranteed spend.

What is a CRM system and why does HMRC need one?

A CRM system records every contact a customer has with an organisation, so any member of staff can see the full history. HMRC’s transformation roadmap of 21 July 2025 said HMRC has “an ageing IT estate” that is costly to maintain and secure. It committed to introducing a new CRM system and replacing legacy systems with fewer platforms.

The roadmap said the first phase would buy the technology and start moving Inheritance Tax onto it. It also promised advisers “access to a single view of each customer and their activity”.

Which Salesforce tools are involved?

Salesforce says HMRC will use several of its products on one platform:

• Agentforce: AI agents that handle routine admin, triage incoming queries and route complex cases to specialist staff
• Data 360: the data platform that joins up records
• Public Sector Solutions and Marketing Cloud: case handling and outbound messages
• Quantexa: a UK firm’s fraud detection tools, which score risk and find hidden fraud networks

Salesforce says trained HMRC staff will keep oversight of every decision about a taxpayer.

What could change for taxpayers?

The changes described are aims, not dated commitments. Salesforce says taxpayers should get clearer information through their preferred channel and need to repeat themselves less. Based on the roadmap and the press release, here is what could change.

1. Fewer repeat explanations. Staff should see your full contact history, whichever tax or channel you used.
2. More digital and AI-first contact. Routine queries are likely to be handled by AI assistants before reaching a person. HMRC’s Ask HMRC assistant already handled about 6.3 million interactions in 2025-26.
3. Faster routing. Complex cases should reach a specialist sooner.
4. More data matching. Joined-up records and fraud tools make it easier for HMRC to spot mismatches between what you report and what it holds.
5. Agents seeing more. The roadmap’s promise of a single customer view for advisers would help agents. No date has been set.

Salesforce says help will remain for people who need extra support. Neither HMRC nor Salesforce has announced any phone line closures as part of the deal.

Where does this fit in HMRC’s digital plans?

The CRM is one part of HMRC’s plan to make at least 90% of customer interactions digital by 2030. The roadmap update, updated 27 July 2026, reported:

• 78% of interactions were digital in 2025-26
• 7.6 million people used the HMRC app
• 19.7 million used the Personal Tax Account
• 10.8 million businesses had a Business Tax Account
• work had started on the new Enterprise CRM
• legacy Corporation Tax systems are due to be replaced by 2028

The update also lists a new contact centre platform with built-in AI and AI call summarisation pilots. The government’s wider AI plan for small businesses cites HMRC as an example of AI in public services.

What is not known

Several important points have not been published.

• Timetable: no milestones or go-live dates for any tax.
• HMRC’s own statement: we found no HMRC press release or GOV.UK news story about the award. Most of the detail comes from Salesforce.
• Which systems are replaced: no legacy systems have been named.
• Agent services: no detail on how the CRM will work with the agent services account.
• The value gap: an earlier tender notice was widely reported at about £1 billion. The reason for the rise to £2 billion has not been explained.

What advisers should do

There is nothing to do yet, but a few steps help prepare.

1. Keep client contact details current. A single customer record relies on accurate data in each client’s HMRC online account.
2. Expect more data matching. Joined-up records make inconsistencies easier to find. Our summary of the NAO report on HMRC tax debt shows where HMRC is focusing.
3. Warn clients about scams. New contact channels can give fraudsters cover. See how to tell if HMRC contact is genuine.
4. Use the right phone line for now. See HMRC telephone numbers.
