How can HMRC better understand the impact of using different digital communication channels compared to more traditional methods of inbound communication from customers?

Background

As part of HMRC’s vision to be a trusted, modern tax and customs department, our strategy is to deliver more of what our customers need through digital services whilst retaining advisor-led services for those who need them, for example those who need assistance to use our digital services, are digitally excluded, vulnerable or have complex tax affairs. Research would consider how we deliver this modernisation effectively to improve customer experience, building on existing evidence and research to understand customer needs, preferences and behaviour.
