An Australian Business Number (ABN) is a unique 11-digit identifier that makes it easier for businesses and all levels of government to interact.

You can run a business without an ABN, but you must have an ABN to:

  • operate in the Goods and Services Tax (GST) system, including claiming GST credits or fuel tax credits
  • avoid having amounts withheld from payments to you – your business clients must withhold 49% of any payments they make to you if you don't give them an ABN
  • help other businesses to confirm your business details for ordering and invoicing
  • get an AUSkey, or use Manage ABN Connections to transact online with government agencies
  • be able to register a website that ends with ‘.au’ for your business.

You can apply online for an ABN.

Apply online
  • your entity type or business structure (for example, sole trader, partnership or company)
  • the legal name of your entity (the meaning of ‘legal name’ depends on your business structure)
  • if you’ve decided to operate your business as a company (instead of a sole trader or partnership), you’ll need an Australian Company Number (ACN) before you apply for an ABN – Register a company
  • the registration number of your tax agent if you have one
  • your Tax File Number (TFN) (use your personal TFN if you’re a sole trader, or apply for a Business Tax File Number if you’re a partnership or company)
  • your business address
  • contact details of a person who is authorised to deal with business matters relating to the ABN
  • personal details and TFNs of all business associates (‘business associates’ are different depending on your business structure)
  • details of your main business activity (for example, food service)
  • the date you require the ABN
  • if you’re re-applying for an ABN that you've used for this same business before, you’ll need the old ABN.

Your business or organisation is eligible for an ABN if:

  • it is a company incorporated under the Corporations Act 2001 (Cth), or
  • it is an entity that carries on an enterprise.

‘Carrying on an enterprise’ is an important eligibility requirement for an ABN. Some indicators that your business activity is carrying on an enterprise are that the activity:

  • is significantly commercial
  • is intended to make a profit
  • is not a hobby
  • is repetitive
  • involves selling products.

Not everyone who applies for an ABN will get one. Visit ABN entitlement at the Australian Business Register website for more information.

Apply online
  • when you apply for an ABN, you can also apply for tax registrations relevant to your situation (for example, you can Register your business for Goods and Services Tax (GST) at the same time)
  • if you apply online, you’ll get your ABN immediately, as long as it’s your first ABN, and you’ve given enough information to prove your eligibility and identity
  • you can apply for an AUSkey at the same time as an ABN (AUSkey is a unique password that allows your business to transact with government agencies)
  • when you get an ABN, some of your business details will be publicly stored on the Australian Business Register 
  • you should put your ABN on your business stationery, especially your invoices (if there is no ABN on an invoice, other businesses will have to withhold 46.5% of their payments to you).
