ABN – Questions & Answers

ABN – Australian Business Number

 Do I need an ABN?

      An Australian Business Number is not compulsory, but it does allow you to:

  • facilitate a single Business Activity Statement (BAS)
  • confirm your business identity to others when ordering and invoicing
  • avoid Pay as You Go (PAYG) tax on payments you receive
  • claim Goods and Services Tax (GST) credits
  • claim energy grants credits
  • obtain an Australian domain name.

Registering an ABN is a separate process to registering a business name.

Registering an Australian Business Number is free.

Yes. Australian Business Number registration is administered by the Australian Taxation Office (ATO). This registration only provides you with an ABN – it does not automatically register your business name.

Business names are administered by the Australian Securities & Investments Commission (ASIC).

The Australian Securities and Investments Commission (ASIC) will give you an ACN when you register your company. You will need to do this before you apply for an ABN.

Further information about ACNs is available on the ASIC website.
