Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what processes are in place to protect the data protection rights of migrants in the event that their personal tax data is used to determine (a) successful and (b) unsuccessful applications for indefinite leave to remain.

HMRC have a duty of confidentiality for information they hold on all taxpayers. HMRC only share or disclose information that is necessary and proportionate for the intended purpose, through strict adherence to data protection principles such as UK GDPR, and only with comprehensive governance in place to monitor those exchanges and the purposes to which data can be used or retained.

In the event that the Home Office and HMRC undertake an exchange in relation to applications for indefinite leave to remain, the processes in place to uphold the data protection rights of migrants are the same as for all applicants. It is the responsibility of the Home Office to determine whether applications are successful or unsuccessful.
