Investigators use OSINT to expose lifestyle gaps that reveal tax and welfare fraud

Ahead of the UK Government’s Spring Forecast next month, investigators are revealing how tax and benefit fraud is increasingly visible in open data.

Advanced investigative technology is helping connect this evidence at the scale needed to support the Government’s multi-billion pound plans to reduce the UK tax gap and raise additional revenue by the end of the decade.

While fraudsters may mis-state income on tax returns or benefits claims, patterns in publicly available information can reveal inconsistencies.

OSINT – the targeted use of publicly available data – enables investigators to spot contradictions between declarations and lifestyle that may indicate fraud.

Investigators commonly encounter indicators such as individuals declaring minimal income alongside online behaviour suggesting a more substantial lifestyle, or corporate records revealing complex networks of companies registered to single addresses.

The evidence exists across publicly viewable social media, online marketplaces, and corporate registries – but each case can require searching dozens of platforms, cross-referencing identifiers, and mapping networks of shell companies. The volume and complexity of modern fraud creates challenges that specialised technology can help address.

A fraud investigator at a government agency explained: “OSINT tools primarily ensure integrity, efficiency, and evidential reliability.

“They remove much of the manual burden associated with advanced search techniques – rather than manually running numerous queries or variations of names, tools can automate and streamline these processes, cycling through multiple parameters quickly and accurately. In short, OSINT tools increase speed, consistency, and evidential integrity throughout the online research process.”

Stuart Clarke, CEO at Blackdot Solutions, added: “The Government’s commitment to tackling tax and benefit fraud is clear, but the scale of investigation required demands smarter tools. OSINT technology empowers investigators to connect dots across dozens of platforms in minutes rather than days.

“This isn’t about replacing investigators’ expertise and skills – it’s about giving them the capability to work at the pace modern fraud demands.”

Platforms like Videris, developed by Blackdot Solutions, enable investigators to collect data efficiently from multiple sources, map complex networks of entities, and identify hidden connections while maintaining human oversight throughout. Investigators report efficiency gains of up to 400% when using OSINT technology, allowing them to identify patterns such as undeclared economic activity advertised online, networks of connected companies, and lifestyle evidence contradicting benefit eligibility.

“Tax and benefit fraud doesn’t just cost the Treasury. Every pound lost to fraudsters is a pound that could have been invested in public services,” Clarke continued. “By identifying fraud patterns and networks early, investigators can disrupt operations before losses escalate, supporting a shift from reactive enforcement to proactive prevention.”
