• What you need for your ABN application

    Avoid delays in getting your ABN by having the right information at hand when you apply.

    • TFN – The quickest way to get your ABN online is by providing your tax file number (TFN) and the TFNs of all associates (such as partners, directors, trustees). We can't issue an ABN if we can't identify the people associated with the business.
      • To apply for an ABN as a sole trader you must already have a TFN. If you're applying for an ABN for another type of entity, you'll need to provide proof of identity documents if you can't provide a TFN for you and your associates.
      • The proof of identity (POI) information you provide will be validated against other sources such as ATO tax records and the Australian Securities and Investments Commission (ASIC) companies register. If these details don't match, your application won't proceed and you'll be asked to provide alternate POI information to avoid your application being refused.
    • Legal name of the entity

      Authorised contact details

      Associates' details

      Business activity details

      Business locations

    • Tax agent number – if you're using the services of a tax agent, you can provide their registration number (see your income tax return or tax agent invoice), which will enable them to undertake work on your behalf.
    • ABN – if the entity you are applying for has previously held an ABN, providing this will help us determine if a new ABN needs to be issued (use ABN LookupExternal Link to check for an existing ABN).
    • ACN or ARBN – before applying for an ABN, companies and registrable organisations need to register with the Australian Securities and Investments Commission (ASIC), which will issue an Australian Company Number (ACN) or Australian Registered Body Number (ARBN).
    • Date ABN is required – The ABN won't be issued until the date you specify, which should be when you expect to start business activities such as buying stock, if you haven't already started. The date you enter can't be more than six months in the future. If you're reapplying for your ABN after it has been cancelled, to avoid delays in processing don't enter a future start date. Your ABN won't appear on ABN LookupExternal Link until the ABN start date.
