Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how HMRC will measure the potential impact of its digital services on levels of taxpayer compliance.

HMRC has a strategy to become a digital-first organisation with a minimum of 90% of interactions undertaken digitally by 2029 to 2030, as set out in the HMRC Transformation Roadmap. HMRC's Transformation Roadmap - GOV.UK

Annex A of the Roadmap sets out the metrics that will be used to measure progress, including on compliance, and these will be reported in HMRC’s Annual Report and Accounts
