    Known issues

    Tax Agent and Business portals - Current system issues are resulting in some new or cancelled ABN, GST and PAYG registrations not being reflected in the Tax Agent and Business portals. Work is underway to rectify this.

    ABN application for foreign companies - we have identified an issue in the Australian Business Register (ABR) online application where foreign companies are unable to get an Australian business number (ABN) or apply for a GST-only registration. 

    We will assist you over the phone until the issue with the online application is resolved. You will need to:

    • phone 1300 146 094 between 8.00am and 6.00pm Eastern Standard Time (EST), Monday to Friday
    • wait until you hear instructions to enter the three digit call-back code
    • enter the call-back code '118' and '#'.

    We are working to resolve this issue and will advise once the online function is available.
