The Australian Taxation Office (ATO) will automatically issue your partnership, company or trust with a business TFN when you apply for an Australian Business Number (ABN).

At the Australian Government's Business Registration website you can register an ABN and business TFN using one online form. The form will also:

  • tell you what information you need to complete your registration
  • allow you to save your progress and come back later
  • give you other helpful information related to ABNs and TFNs
  • let you make other business registrations you may need.
