Help: Link a business
Troubleshoot common issues and errors associated with linking a business as a principal authority.
Published 7 August 2025
Common issues
- no longer operating – you need to cancel the Australian business number (ABN)
- still operating but you’re no longer the associate – you need to update the Australian Business Register (ABR) details.
If the business is already linked in RAM then you can update your details or cancel your ABN using ABR online servicesExternal Link.
If you didn’t link the business online in RAM (you appear in RAM as a Government representative, Indirect associate or Responsible authority) you’ll also need to remove your authorisation for the business in RAM.
If you're unable to set up a Digital ID, such as myID, with a Standard or Strong identity strength, you won’t be able to link your business in RAM at this time.
Alternatively, you can:
- Check if another principal authority can achieve a Standard or Strong Digital ID – they can link the business in RAM instead and authorise you to access some services as a Basic user.
- Contact the relevant service you want to access to find out about other options for your business – for example, using cloud-based Standard Business Reporting (SBR)-enabled software.
