Records: agent record: introduction
All tax agents, advisors or accountants, who wish to act for their clients in respect of Self Assessment (SA), must be issued with an SA agent code. The allocation of agent codes has been centralised and the Agent Maintainer Team, within the Central Agent Authorisation Team (CAAT) at Longbenton, deal with the setting up and amending of all agent records for SA.
Local offices must not set up new agents on the SA database. The Agent Maintainer Team in CAAT, who have full access to the Agent Maintainer role in SA, must set up all new SA agents.
Only the SA agent code is entered on the customer’s SA record. Full details of the SA agent are held on the national database and can be retrieved when you enter the SA agent code onto the SA system (CESA).
To obtain an SA Agent Code, the new agent must write to HMRC and provide the business name, name of the partner/director of the business, address and telephone number together with confirmation that they require a Self Assessment Agent Code and send to
