Australian Business Number (ABN) Information

What is an ABN?

An Australian Business Number (ABN) is a unique 11-digit identifier issued by the Australian Taxation Office (ATO). It's essential for businesses operating in Australia as it:

  • Identifies your business to government and the community
  • Facilitates GST and other tax registrations
  • Allows you to claim tax credits
  • Helps avoid PAYG tax being withheld from payments to you
