Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what additional tax liabilities were identified through compliance activity relating to tax relief claims in each of the last three tax years, broken down by relief where such information is held.

HMRC undertakes internal assessments of compliance risks to inform the deployment of its resources. It does not routinely publish detailed relief-level risk assessments or estimates as doing so could provide insight into HMRC’s compliance approach and undermine its ability to protect the Exchequer.
