Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 19 November 2025 to Question 89703 on Child Benefit, if she can advise what is the most localised level for which data is available.

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. There are no plans to publish a report.

In the response to the Treasury Select Committee, HMRC provided figures for those customers subsequently confirmed as eligible through a PAYE check or customer contact up to and including 31 October 2025. This time period reflects that figures are only validated after the month end.

Where there was evidence that customers had continued UK employment, HMRC reinstated payments automatically without any need for customer contact and those payments have been backdated. By the end of November 2025, HMRC will have written to all customers who have not yet contacted them to provide a further 4 weeks in which to make contact.

HMRC holds information by postal address although HMRC would be unable to release to such a granular level due to the risk of breaching taxpayer confidentiality.

HMRC’s pilot last year using international travel data prevented around £17m in incorrect payments. This led to a wider rollout and investment in an additional 180 counter-fraud staff, announced at the Autumn Budget 2024, which is expected to save around £350 million over the next five years.
