    You can update your business details by :

    • phoning 13 28 66 
    • contacting your nominated tax agent
    • mailing
       

    For tax agents

    If your Tax agent number (TAN) is recorded against your client’s ABN record, you can update certain client details through the Tax Agent Portal.

     
    When updating your details in the Australian Business Register (ABR), it is important that the information you provide is true and correct - making false or misleading statement to the ABR may result in penalty.

    For more information on the penalty and voluntary disclosure, refer to the Penalties for false or misleading statements made to the Australian Business Register.
