HMRC asks agents to use Agent Dedicated Line for employer-related queries

28 October, 2026

HMRC is encouraging tax agents with employer-related queries to contact the Agent Dedicated Line (ADL) rather than the Employer Helpline.

The change forms part of an ongoing trial aimed at providing a more consistent service for agents, with queries handled by advisers who have specialist knowledge of agents’ needs and the issues they encounter. HMRC says the trial will also help it gather insight to inform future improvements for agents.

The Employer Helpline will remain available for queries from individuals.

ATT members with employer-related queries are therefore encouraged to use the Agent Dedicated Line during the trial.

HMRC has also advised that an Agent Update article is due to be published on 19 November to raise awareness of the change.
