Question to the HM Treasury:

To ask His Majesty's Government what assessment they have made of the accuracy of Home Office travel data used in determining immigration status; whether this has involved 24,000 families having their child benefit stopped; whether any failures in accurate determinations would breach the principles of accuracy, fairness and transparency set out in the UK General Data Protection Regulation; and whether they plan to cease the use of Home Office data in assessing immigration status.

HMRC do not use Home Office international travel data to determine immigration status. HMRC uses the data as a starting point for identifying potential unreported absences from the UK. Undetected changes to an individual’s residency status are a leading cause of Child Benefit error and fraud.

HMRC’s Chief Executive wrote to the Treasury Select Committee on 14 November 2025 about this matter including the corrective action that HMRC is taking. This letter was subsequently published by the Committee on 18 November 2025.

It was understood from the outset and made clear by the Home Office that its international travel data could not be used in isolation to determine Child Benefit entitlement, therefore requiring HMRC to conduct its own checks and enquires with recipients to establish eligibility. The same data was used during a pilot in 2024 which allowed HMRC to focus their enquiries on less than 2% of recipients while preventing £17m in incorrect payments. This led to the expansion of the measure and investment in an additional 180 counter-fraud staff, announced at the Budget in 2024 and is expected to save around £350 million over the next five years.

When using international travel data complemented by a check of UK employment using the Pay As You Earn (PAYE) system, HMRC will no longer suspend payments at the outset of its enquiries. Instead, recipients will be given at least one month to evidence their entitlement. HMRC will continue to iterate the process where its monitoring and learning suggests that it should make further changes.
