An HMRC pilot that used Home Office passenger-movement data to flag suspected benefit fraud has mis-identified 46 % of targeted families, according to Guardian reporting published this morning. The scheme automatically suspended payments where travel records suggested parents had been abroad for more than eight weeks, but records often failed to capture return journeys—particularly when families flew back via Dublin or changed modes of transport.
The fallout highlights growing use of immigration-border databases for domestic policy enforcement. Some 23,500 households—many of them cross-border commuters or dual-nationals—received suspension letters; in Northern Ireland the false-positive rate reached a staggering 78 %. HMRC has now paused automatic stops, pledged to cross-check PAYE records first, and promised claimants a 30-day response window before money is withheld.

For international assignees the episode is a cautionary tale. Dependants frequently undertake circular travel while awaiting visa decisions, and erroneous data could trigger loss of benefits or—by extension—NHS surcharge liabilities. Mobility managers should advise affected employees to keep boarding passes and digital-entry confirmations, especially when using common-travel-area routes that bypass UK exit checks.
The controversy also raises privacy questions. Immigration barristers argue the Home Office risked breaching data-protection principles by repurposing travel logs—originally collected for border security—for welfare policing without adequate accuracy safeguards. MPs across parties are calling for a formal inquiry and for HMRC to publish its data-impact assessment.
In practical terms the agency says most wrongly suspended payments will be reinstated within 14 days once claimants confirm UK residence. Employers with staff on assignment should monitor reimbursements closely to ensure no net-pay anomalies in November payroll.
