Getting an Australian Business Number (ABN) is one of the first important steps when starting a business. An ABN helps the government, customers, and other businesses recognise that your business is legitimate. If you don’t have an ABN, you can’t send invoices, apply for funding, or complete many other important registrations.
ABNs are provided by the Australian Business Register, and applying for one is free. However, it’s essential to take your time and complete the application carefully. Many people face delays or have their applications rejected because they hurry through the process or don’t provide all the necessary information.
Before you start your application, it’s important to make sure your business is ready to go. An Australian Business Number (ABN) is given to businesses that are either already up and running or are actively preparing to start, not just to ideas that haven't been put into action. The government wants to see proof that you are genuinely working on your business.
You should be ready to explain a few key things:
When you start applying for your Australian Business Number (ABN), it's important to have all the right information ready. This will help your application go through smoothly and avoid any delays.
First, you'll need your Tax File Number (TFN). If there are other people involved in the business, you'll also need their TFNs. The application system checks this information with the Australian Taxation Office, so make sure that names and birth dates are correct.
You'll also need to provide your full legal name as it appears on official documents like your driver’s license or Medicare card. Avoid using nicknames, as they can cause problems with your application.
It’s important to know when your business started trading or when you plan to start. This date doesn’t have to be perfect, but it should make sense based on your business plans.
Lastly, make sure you have your business contact details ready, including an address, email, and phone number. This information will be included in your public ABN record.

When applying for an Australian Business Number (ABN), always use the official Australian Business Register website. Be cautious, as some other websites may look official but charge extra fees that you don’t need to pay. Getting your ABN through the official site is completely free.
As you fill out your application, you'll need to confirm that you understand it will be checked to make sure only legitimate businesses get an ABN. It's really important to provide correct information because giving false details could lead to costly fines.
If you get your ABN and later change anything about your business or decide to close it, you have to update your ABN information within 28 days.
Once you agree to the terms, you'll need to confirm how your business is set up. This is an important part of the application process. You’ll need to choose one of the following options:
Your choice will affect how you're taxed, what reports you need to submit, and if you have to do any extra paperwork. If you need help choosing which business structure is right for you, see Choosing a Business Structure.
When you choose your business structure, you will be asked if your business activities will happen in Australia. This means you'll need to consider whether you will be delivering goods to Australia, making them available in the country, or removing them from Australia. It also applies if you plan to bring items into Australia to sell, install, or put together. Additionally, if you’re supplying something that is either delivered in Australia or connected to a business based in Australia, this counts too.
Next, you'll need to indicate whether you have started any work on your business. This means doing something beyond just having an idea. Here are some examples of activities that show you’re getting started:
If you’ve done any of these things, you should answer 'yes' to show that you’ve begun your business journey. If not, then it’s okay to select 'no.' This isn’t a trick question; it's just a way for the Australia Business Register to see how committed you are to starting your business. They want to know that you’ve at least made some progress.
The nature of your activity:
When you fill out your application, you'll need to explain what your business does. This is an important step. It's essential to note that if you say you're an apprentice, trade assistant, or labourer, you won't be able to get an ABN because those jobs are considered employment, which means you work for someone else.
To qualify for an ABN, you need to be starting your own business. Here are some examples to help you understand what that might look like:
Select: In the form of a business
If you are an independent contractor, this includes subcontracting/delegating work, being paid on quotes rather than a salary, providing your own equipment or tools, and controlling the work.
As a Taxi and ride-sourcing driver, this means supplying taxi travel under a bailment agreement or providing your own vehicles to earn income.
If you perform any activities in a business context, including those carried out by mutual organisations such as clubs and societies, non-profit organisations, and body corporates under strata title legislation.
Select: Renting or leasing out a residential property
If you intend to rent out a residential property on a regular or continuous basis, however, if you rent a property that is used for residential accommodation, meaning for someone to occupy, you do not need an ABN.
Select: In the form of a licence, lease or other grant of an interest in property
If you regularly or continuously carry out activities in the form of licences, leases or interests in property.
Select: One-off commercial transaction not done in the course of a business
If you do not intend to use the ABN after a one-off activity, such as selling a house, or something else that will bring in the expectation of profit. If you select this one, you are not entitled to an ABN.
The application will ask questions to confirm that you are genuinely operating or preparing to operate a business. These questions are designed to prevent people from applying for ABNs for private or non-business reasons.
Once you have made your selections, you will be asked to confirm them. If anything seems inaccurate at this stage, go back and correct it now. Once you select Next, you cannot return to your ABN entitlement form.
Once you arrive at the application detail, you will enter personal details for the business owner or the responsible person. If you selected Sole Trader, then only add your details, but if you selected something else, you will need the details of everyone involved. These details are checked against ATO records.
Take care to enter your details accurately. Even minor errors, such as spelling mistakes or incorrect dates, can delay processing your application.
You will also confirm your business address and contact details. Some of this information will be visible on the public ABN Lookup, so ensure you provide contact details you are comfortable sharing publicly.
Before submitting, review every answer carefully. This is your chance to fix mistakes before they cause delays.
You will be required to provide the reason for your application and complete a declaration confirming that all information provided is accurate.
Once your application is submitted, many ABNs are issued immediately. If your ABN is approved straight away, you will receive confirmation on screen and by email.
In some cases, the application is reviewed manually. This can take up to 28 days. If this happens, the Australian Business Register may contact you for more information or send confirmation by post.
Once your ABN is issued, keep a record of it. You will use this number regularly for invoicing, registrations, and government dealings.
Your ABN details will appear on ABN Lookup. Check that the information is correct. If something is wrong, it can usually be updated online.
Having an ABN does not automatically mean you have done all registrations. You may still need to:
One common mistake is applying too early, before the business is ready. Another is using inconsistent information, especially names and dates.
Some people apply for multiple ABNs because they think the first one did not work. This often causes more delays. If you have already applied, wait for the outcome or contact the ABR.
Another mistake is assuming that having an ABN means you are fully compliant. An ABN is the start, not the finish.
If your application is delayed, rejected, or confusing, free help is available. Business Queensland Advisory Services, Indigenous Business Australia, and Many Rivers can help you understand what the ABR is asking for and how to respond.
Getting help early is always easier than fixing problems later.
Remember that an ABN is more than a number. It is the first formal step in building a business that can grow, trade, and stand on its own. Taking the time to apply carefully shows that you are serious about what you are building and helps protect you as you move forward.
