HMRC introduced a data-driven anti-fraud scheme between July and October of the previous year, designed to detect claimants who might be ineligible for child benefit due to residence abroad.
The scheme was based on international travel information received from the Home Office, with the intention of ensuring that public funds were directed only to eligible recipients. This approach formed part of a broader government effort to combat benefit fraud and protect the integrity of welfare payments.
However, the implementation relied heavily on the accuracy and completeness of shared government data, especially records of travel movements in and out of the UK.
Use of Home Office Data and Resulting Issues
According to the NAO, the Home Office provided travel data that recorded outbound journeys, such as flight bookings, but did not always capture return journeys. In some cases, records included flight reservations for trips never taken and omitted data from travellers returning via different routes,
including through Irish airports, or not flying at all. This incomplete and sometimes inaccurate information led HMRC to erroneously conclude that certain families had moved abroad while continuing to claim child benefit.
As a consequence, benefits were suspended for many families who remained eligible under the scheme’s criteria.
Scale and Impact of Suspensions
HMRC suspended child benefit payments to 23,794 families in the initial four-month phase of the scheme. Letters were sent to parents referencing previous travel, including holidays dating back up to three years, for which no return to the UK could be verified through Home Office data.
By the end of December, HMRC confirmed that over 17,000 of the suspended cases were legitimate claims, while around 1,019 families (representing 4.3% of cases) were found to be ineligible. Thousands of cases remained unresolved as of the last available data.
The number of eligible families is expected to rise as further assessments are completed. Some affected individuals reported severe disruption, with payments halted during ongoing reviews.
Political and Public Response
The suspension programme has drawn significant criticism within Parliament and among the public. Conservative MP Andrew Snowden expressed concern over what he described as a lack of transparency in the scheme’s design, data sources, and the error rate associated with the suspensions. Snowden stated,
“Parliament has had to rely on written questions and piecemeal disclosures to understand the scale of the problem,” and called for greater clarity regarding accountability and future safeguards.
Advocacy groups have raised concerns over families being penalised for issues such as cancelled trips or emergencies that prevented travel abroad, as well as for simply returning by routes not tracked in the official records.
Internal Evaluation and Policy Changes
Internal documents reviewed by the NAO and confirmed by HMRC show that, despite issuing public apologies, officials initially viewed the data-sharing exercise as effective. One report submitted to the Cabinet Office in November last year maintained that the exchange of data was proceeding as planned and anticipated a majority of cases would be ineligible for child benefit.
However, by the end of the month, official figures indicated the majority of suspended families were, in fact, entitled to their payments, with the proportion rising to 71% by the end of December. HMRC subsequently abandoned the policy of halting benefits before fraud was established.
John-Paul Marks, Chief Executive and First Permanent Secretary at HMRC, wrote to the Treasury Select Committee confirming a revised approach focused on improved customer support and assurance on the review process.
He indicated that an oversight group would monitor use of international travel data and update procedures as lessons were learned.
Next Steps: Oversight and Accountability
The NAO inquiry will review HMRC’s strategy, scheme governance, risk management, and data deployment practices, to ensure errors are not repeated and claimants are treated fairly.
The oversight group is expected to provide regular updates, and Marks has committed to informing the Treasury Select Committee on progress this summer, taking into account the NAO’s findings. HMRC has not released new figures on the number of resolved or ongoing suspensions since December.
The agency has signalled a more cautious and transparent approach in future interventions, with increased stakeholder input and oversight.
Final Summary
The NAO’s investigation represents a significant point in efforts to address errors made under HMRC’s anti-fraud child benefit scheme. The reliance on flawed travel data led to widespread disruption for thousands of families, the majority of whom were ultimately shown to be claiming legitimately.
Political leaders and advocacy groups have emphasised the need for greater transparency, improved data management, and accountability in similar operations. The final review is expected to offer recommendations aimed at preventing such failures.
