TL;DR

HM Revenue & Customs plans to place officials on online forums and social media as “digital ambassadors” to point people to correct tax information, according to a Bloomberg report syndicated by Business Standard on 22 October. The department is also reworking its guidance so that large language models are more likely to pick it up, after chatbots and search summaries repeated wrong advice.

The problem HMRC found

The trigger was a case earlier this year in which search engines and AI-generated summaries gave businesses the wrong VAT deadlines. HMRC traced it to a single website whose content had been copied onto other sites, shared on social media and then absorbed by AI tools. Anyone who relied on it risked missing a deadline and paying a penalty.

James Baker, HMRC’s head of digital communications, told Bloomberg: “Where sources conflict, trust falls and the risk of costly errors rises.” He said the episode showed how people now jump between “search engines, AI tools, apps and social platforms” when looking for answers.

The stakes are financial. Bloomberg puts the UK tax gap at £59 billion ($79 billion), with small businesses the largest contributor, and notes that smaller firms may lack the expertise to spot inaccurate advice online. It also cites a Finder survey putting the share of Britons who have used AI tools for financial advice at about three in 10.

What HMRC is doing

The ambassadors will be managers acting, in Baker’s words, as “a proactive digital equivalent to HMRC’s broadcast spokespeople”, engaging on sites such as Reddit. Alongside them, an “HMRC Verified” alert system aims to counter false claims online and steer language models to official answers; HMRC says the models have responded and surfaced the correct information.

The department is also scoping an AI-assisted tool that would find claims made online, compare them with official guidance and draft a reply for a person to approve. Staff have been told to make content “LLM ready” ahead of its launch.

Looking forward

Baker’s summary was blunt: “Authority no longer lives on your website alone.” HMRC’s approach treats chatbots as a distribution channel it has to manage, not just a source of error. The question for other public bodies, and for firms whose customers ask AI about their products, is the same: whether their own content is written so that models repeat it accurately. It sits alongside the FCA’s request to AI providers about financial disclaimers. For small businesses, the practical advice is to confirm any deadline or rule from a chatbot against GOV.UK before acting on it.
