• Update your details

    It is a legal requirement to tell the Registrar of the Australian Business Register (ABR) within 28 days of any changes in your registered business details. These include changes to your:

    • postal, email or business address
    • associates
    • main business activity
    • Australian Company Number (ACN) or Australian Registered Body Number (ARBN)
    • public officer (this must be in writing and include the public officer's name and a contact address)
    • name of trustees.

    You should also tell us about any changes to your:

    • entity name or registered business name (registered with the Australian Securities & Investments Commission)
    • authorised contact person
    • financial institution account details.

    We use this information to update the ABR. We may pass on the changes to other government agencies where we are authorised to do so.

    How to update your details

    You can update your details:

    Authorised contact

    Only primary contacts (including public officers), authorised contacts, registered tax agents, registered BAS agents, temporarily appointed tax professionals and specialist tax advisers can contact us on behalf of an entity.

    Different entity types will have different primary contacts. For example:

    • If the trustee for a trust is a company, the primary contact will be the public officer.
    • If the trustee is a company that isn't registered with us, and therefore doesn't have a public officer, it is the director of the trustee company as listed with ASIC.
