Digital strategy statement

…making registering to act as an agent easier and quicker… agents will have the tools to take more control of their clients’ tax affairs and undertake transactions for them with minimal involvement from HMRC… any new IT services developed for individual customers should be available to agents.

Scope of exemplar

This is a new service for tax agents to work with HMRC online. It will let agents register to act on behalf of, and see information about, their clients, and to control a range of transactions on their behalf. These will be built on a new digital tax platform which will eventually replace the current HMRC Portal and be the default platform for new user-facing services.

Digital inclusion

GDS has mapped the exemplars against the digital inclusion scale to help show where these services may be difficult for some people to use. See the rating for Agent online self-serve.
