Question to the HM Treasury:
To ask Mr Chancellor of the Exchequer, what performance indicators HMRC has in respect of its customer service.
The HM Revenue and Customs (HMRC) single departmental plan lays out its objectives and how it will achieve them. https://www.gov.uk/government/publications/hm-revenue-and-customs-single-departmental-plan/single-departmental-plan
Furthermore, its detailed customer service performance indicators are published monthly on the GOV.UK website:
