• Accessing our digital channels

    To access our digital channels you will need an AUSkey.

     An AUSkey is a single key that identifies you, or the nominated representatives of your business, when engaging online with government agencies. You will need your AUSkey to complete your online transactions – for example, through the portals, Access manager, Standard Business Reporting, electronic commerce interface (ECI) and the Australian Business Register (ABR).


    For more information about ensuring the security of your credentials, refer to the Best practices guide for the use of security credentials.


    Accessing the portal


    The login screen is displayed when a request is made to use an ATO system that requires you to be authenticated as the holder of an AUSkey. The ATO system will require you to nominate the security credential and enter a password associated with that credential.

    Log in to the Business Portal.

    For more information, visit Login.


    You will need to re-log in when your session has expired. A session is expired when a set period of time has elapsed since you last interacted with the system without logging out.

     For more information, visit Re-login.



     This is achieved from within the system you are logged onto. Each ATO system may have its own method of exiting. Typically there will be a link that signifies the log out or exit function.

     For more information, visit Logout.
