Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 3 October 2025 to Question 85934, if HMRC utilised or was given access to passenger name records as part of the Data Usage Agreement with the Home Office.

HMRC did not directly access passenger name records held by the Home Office as part of its efforts to reduce Child Benefit non-compliance. The process involves HMRC sharing a data set with the Home Office, which includes the Child Benefit claimant’s name. Matches returned by the Home Office also include the Child Benefit claimant’s name. Both data sets were assessed and agreed for data minimisation purposes.
