Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 7 April 2025 to Question 43135, what historic information she holds on taxable state pension payments to people who are now deceased; and whether her Department would supply such data on request to the Department for Work and Pensions where a potential state pension underpayment is under investigation by that Department.

The Department for Work and Pensions (DWP) and HM Revenue and Customs (HMRC) share information via an established legislative gateway for the administration of the State Pension.

When HMRC receive updates on State Pension payments from DWP, they store it for any tax years still subject to an end of year reconciliation check. The same process takes place for deceased customers.

While HMRC may hold information on State Pension received from DWP to ensure the collection of tax, it complies with General Data Protection Regulations by deleting any customer data that is outside of the retention period for tax purposes.
