Could your latest LinkedIn post expose you to tax penalties?

HM Revenue and Customs (HMRC) has confirmed it uses AI to scan social media posts as part of criminal investigations into suspected tax and benefits fraud.

That means, if you are posting content that could be viewed as advocating for, admitting to, or describing tax avoidance, you could find yourself at the centre of legal action.

Why is HMRC browsing social media?

HMRC says AI tools have been used for several years to compile and analyse data.

It is keen to assert that it is only in criminal cases where fraud is suspected that social media checks are being conducted.

The move comes as the department is expanding compliance resources following the Government announcement of 5,500 new compliance staff.

The technology supplements human judgement and operates under legal oversight, and it is intended to free up staff to focus on helping taxpayers and targeting evasion.

Does AI help to catch fraud?

AI can pull together publicly available information from platforms and flag pieces of evidence that merit human review.

In practice, investigators have long read suspects’ social posts to spot discrepancies.

Automation speeds the collation and helps prioritise cases for investigators, but the process is not entirely without risk.

Experts caution that fake, hacked or misattributed accounts could generate false leads.

Automation may also miss context that a human reviewer would catch, so robust oversight is essential.

Be mindful of what you post online, as even jokingly describing the steps to avoid tax might put you on HMRC’s radar.

If you have any concerns about under-declaring your tax, speak to a professional confidentially rather than posting about it on social media.

This will let you get control of the situation without automatically being detected by HMRC.

If you are unsure about your position, seek professional advice before making voluntary disclosures or amending returns.
