Do I need an ABN (Australian Business Number)?

An ABN is a unique 11 digit number that identifies your business to the government and community.

It doesn't replace your TFN tax file number, or your ACN Australian Company Number (if your legal entity is a Company).

You can use an ABN to:

✅ Identify your business to others when ordering and invoicing;

✅ Avoid pay as you go (PAYG) tax on payments you get;

✅ Claim goods and services tax (GST) credits;

✅ Claim energy grants credits; and/or

✅ Get an Australian domain name.

To obtain an ABN you need to be running a business or other enterprise.

It is compulsory for businesses with a GST turnover of $75,000 or more to have an ABN and to be registered for GST.

Before you register, please ensure you have the following:

⚖️ Decided Your Business Structure or Legal Entity, and have the details on hand;

⚖️ Proof of Identity;

⚖️ Be able to provide details of your business activities or proposed business activities + associates.

You can use the ABN Lookup website to look up information about a registered ABN.

For example, to check:

✅ That your ABN details are up-to-date; and

✅ The details of a supplier.

ABN Lookup allows you to search publicly available information supplied by businesses when they register for an ABN.
