What is an ABN and why is it important for freelancers and sole traders?

An ABN is an Australian Business Number issued by the Australian Business Register (ABR) which is managed by the ATO (Australian Taxation Office). It’s an 11 digit number that helps you get paid and manage your business transactions for tax purposes.

You can’t invoice for work performed without an ABN, which is why it’s essential to get an ABN for your business.

Once you get your ABN, you’ll be able to register for GST (Goods and Services Tax), register for PAYG (Pay As You Go) if you’re hiring employees and register your business name.

Types of ABN

Depending on the kind of business you run and your business structure, there are different types of ABN for you to consider while filling out the application:

  • Individual/ Sole trader
  • Company
  • Partnership 
  • Trust 
  • Super Entity

What happens after you submit your application?

Once you’ve submitted your ABN application, there are three possible outcomes:

1. Your application is successful

If your application is successful, you’ll receive your ABN number immediately. That means you can start to invoice clients and apply for other business registrations. Your details will automatically be added to the Australian Business Register.

2. Your application needs more information

In some cases, the ABR might need more information from you. You’ll receive a reference number with some questions requesting more information. If your application has been approved, you’ll get a confirmation and your ABN in 14 days.

3. Your application is turned down

If your application is unsuccessful, you’ll be given a “refusal number”. The ABR will send you a letter within 14 days explaining why your application was refused and what other options are available to you.
