Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many people were underpaid the State Pension due to incorrectly updated National Insurance records in the 2022-23 financial year; and what the total amount is that these people are owed.

This response covers both missing Home Responsibilities Protection (HRP) and UC National Insurance issues.

The exercise to correct National Insurance records for those individuals impacted by errors in their HRP record is underway. The HRP corrections exercise started with HMRC dispatching letters in late 2023. Cases subsequently notified from HMRC started being processed in DWP in early 2024.

In the Department’s Annual Report and Accounts 2022-2023, the central estimate was around 187,000 cases who may have an underpayment of State Pension and for whom we expect to correct, with a total underpayment estimate of £1,043 million.

We intend to publish an update on the exercise in this year’s Annual Report and Accounts.

DWP has corrected the UC data issue for the cases impacted for the tax years up to and including the tax year 2022/2023. This data has been shared with HMRC. As HMRC updates NI records, these updates are sent to DWP. Any State Pension entitlement will be reassessed, and any underpayment addressed accordingly.
