If you're starting a business in Australia, one of the first things you'll need is an Australian Business Number (ABN). Whether you're a sole trader, freelancer, or setting up a company, an ABN identifies your business to the government and community.

What is an ABN?

An ABN is an 11-digit number that identifies your business to the Australian government and the public. It's used when dealing with the Australian Taxation Office (ATO) and other government departments, and it's required for invoicing, claiming GST credits, and avoiding PAYG withholding tax on payments you receive.

Who needs an ABN?

You need an ABN if you're carrying on a business in Australia. This includes sole traders, partnerships, companies, trusts, and not-for-profit organisations. You may also need one if you're a contractor or freelancer providing services. Even if your business is small or part-time, having an ABN ensures you can operate legally and get paid without extra tax being withheld.

How to apply for an ABN: step by step

Step 1: Check your eligibility. Before applying, make sure you're entitled to an ABN. The Australian Business Register (ABR) has an online tool to help you determine this.

Step 2: Gather your information. You'll need your Tax File Number (TFN), details about your business structure, and information about your business activities.

Step 3: Apply online. Visit the Australian Business Register website at abr.gov.au and complete the application form. The process typically takes around 20 minutes.

Step 4: Receive your ABN. If your application is straightforward, you may receive your ABN immediately. In some cases, the ATO may need additional information, which can take up to 28 days.

How much does an ABN cost?

Applying for an ABN through the Australian Business Register is completely free. Be wary of third-party services that charge fees for what is otherwise a free process.

What to do after getting your ABN

Once you have your ABN, you should register for GST if your annual turnover is expected to exceed $75,000. You'll also want to set up proper invoicing and consider registering a business name if you're trading under a name different from your own.
