Why share information with the Department for Work and Pensions?
The functions of the Department for Work and Pensions (DWP) are similar to many of the functions of HMRC. In particular the two departments overlap when dealing with National Insurance Contributions (NICs), tax credit applicants, social security benefit claimants and pension credit claimants. DWP may also request HMRC information on behalf of a local authority. This is because local authorities have a role in the administration of social security benefits in the form of housing benefit and council tax benefits.
