• Update your ABN details

    It is your responsibility to maintain your Australian business number (ABN) details. You must update your details within 28 days of becoming aware of changes.

    Once you are registered your ABN details become part of the ABR. It is important that your details are up-to-date so that other businesses can access and verify your information, for example, that you are operating a business or the status of your GST registration.

    Your ABN details are also used by a range of government agencies to plan for community services and infrastructure development that can benefit business.

    What can be updated

    • legal name of the entity (except individual/sole traders and companies registered with Australian Securities and Investments Commission (ASIC) who you will need to contact directly)
    • addresses – postal, business location, email
    • ANZSIC – main business activity and industry code
    • entity type – business structure, for example, private company to public company
    • contact details
    • associate details.

    How to update

    The fastest way to update your details is online using an AUSkey.

    All changes made to your ABN online will take effect immediately.

    Alternatively you can contact us or lodge a form by mail.
