Every business in Australia needs an ABN, or Australian Business Number. This 11-digit identifier is assigned when you register for an ABN, and it’s used for important things like taxes and business transactions. Your ABN is unique to your organisation, so keep it handy; you’ll be using it a lot.

A tax file number is non-negotiable for any Australian business. It’s a must-have, regardless of your company’s scale.

Benefits of having an ABN

Having an ABN comes with a bunch of perks. It lets you:

  • Avoid pay-as-you-go (PAYG) tax on payments you get
  • Claim energy grants credits
  • Register an Australian domain name
  • Identify your biz to others when ordering and invoicing

Plus, some suppliers and customers won’t do business with you unless you’ve got an ABN. It’s like your business registration  passport.

Need an in-depth guide on the benefits of having an ABN? Look no further, we have created just the guide for you. 

Consequences of not having an ABN

On the flip side, if you don’t have an ABN and you’re running a business, you could face some serious consequences. For starters, your clients might have to withhold a whopping 47% from any payments they make to you. Ouch.

You also won’t be able to register for GST, claim energy grants credits, or get an Australian domain name. Clearly, it’s just not worth the hassle.
