HMRC agent access
Different logins to access HMRC services for agents
If you're an accountant, bookkeeper or other adviser helping your clients using untied, you'll know there are two logins to HMRC depending on the service.
Finding them isn't always easy - so we've put the links here.
To the old green service (HMRC online services for agents or OSA) - https://www.gov.uk/log-in-register-hmrc-online-services
For the new blue and black service (the agent services account or ASA) - https://www.gov.uk/guidance/sign-in-to-your-agent-services-account
