Tax Investigations Surge: HMRC’s Connect Tool

HMRC’s Connect Tool Raises £4.6bn in Just One Year as Tax Investigations Surge
HMRC’s powerful data analysis tool, Connect, has raised an additional £4.6bn in the 2024/25 tax year alone. This translates to a 35% jump on its previous annual average of £3.4bn, according to data released under a Freedom of Information request by Pinsent Masons.
Connect, launched in 2010, pulls data from numerous sources, including third-party and merchant acquirer data, to help HMRC identify patterns and links that would otherwise go unnoticed. Crucially, it does not access browser histories, emails, or monitor social media. Around 4,300 HMRC staff now use Connect as a core part of their compliance toolkit, leading to 540,000 tax investigations in just one year.
This comes at a time when tackling tax avoidance is high on the government’s agenda. The Labour government has set an ambitious target of raising an additional £5bn annually through compliance measures by 2027. Connect will be central to this effort.
Although not explicitly referenced, it’s difficult to overlook the potential impact of the surge in HMRC’s ‘nudge letters‘, designed to prompt taxpayers to disclose income HMRC believes may have been omitted, on the overall increase in tax raised.
