Link bulk ABNs in RAM

A principal authority needs to link to the business in Relationship Authorisation Manager (RAM) before others can be authorised to access government online services on behalf of the business.

This page provides instructions for principal authorities on how to link more than five ABNs (to link five or fewer ABNs, go to Principal authority).

Where a principal authority or authorisation administrator is already acting on behalf of the business online, they can authorise you in RAM to act on behalf of the business.

The principal authority is a person responsible for the business, such as:

  • a sole trader
  • an eligible individual associate listed on an Australian business number (ABN) in the Australian Business Register (ABR), for example a
    • trustee
    • director
    • public officer
    • partner
    • an office bearer of a club or association
  • a primary person (no individual associates listed in the ABR) who holds one of the following roles
    • company – the director or public officer for the corporate trustee or subsidiary company
    • government entity – the authorised contact
    • Australian charity or not-for-profit organisation – director or public officer of the corporate trustee or subsidiary company or the Responsible Person
    • deceased estate – the executor after probate is granted
    • unincorporated association – the office holder.
