An Australian business number, or ABN, is a unique 11 digit number used to identify businesses. You use your ABN to interact with other businesses and government departments and agencies, like the Australian Taxation Office (ATO). Even if your business has the same name as another business, no-one else will have the same ABN.
An ABN does not replace your tax file number (TFN).Your business will usually need its own TFN, unless you are a sole trader - then you can use your personal TFN.
You do not have to have an ABN, but having one will avoid having amounts withheld from payments to you. It will also make it easier for you to register for goods and services tax (GST) and other business tax registrations such as pay as you go (PAYG) withholding.
Not everyone is entitled to an ABN. To be entitled to an ABN you must be carrying on a business in Australia. This means that you must have started trading or have undertaken business-like activities towards the commencement of trading.
If you provide services as an employee or undertake activities as a hobby, you are not entitled to an ABN for those services and activities.
If you are a sole trader, you can work out if you are entitled to an ABN by:
Not everyone is entitled to or needs to have an ABN. If someone tells you to apply for an ABN, think carefully about whether you are entitled to one.

It is free to apply for an ABN. However, if you use a tax practitioner or another service provider to complete your application for you they may charge a fee for their services.
It’s important to choose a registered tax agent or BAS agent. Using a registered agent means they are qualified and experienced with tax and only a registered agent can legally charge you a fee.
You can check that your tax or BAS agent is registered by looking at the list on the Tax Practitioners Board’s website tpb.gov.au or phoning them on 1300 362 829
As part of the online ABN application process, you can:
You will only have to complete your details online once as your information will be pre-filled from one registration to the next.
If you do not apply for these registrations at the same time as your ABN application, you will need to do so directly with the other government agencies who manage those registrations. We manage AUSkey, GST and PAYG registrations. The Australian Securities & Investments Commission (ASIC) manages national business name registrations.
Provided you are entitled and your details can be verified you will receive your ABN when you apply for it. We will then send you written confirmation. If you don’t give us all the information we ask for or your details cannot be verified, we will process your application manually which could take up to 28 days.
If you hold an ABN, legally you must notify the ABR within 28 days of any changes, such as changes to your name, address and other contact details.
If the ABR writes to you requesting information about your ABN entitlement or to confirm your identity or other details in the register, you must comply with this request.
If you are no longer in business you need to request to have your ABN registration cancelled. You should do this once you have met all of your tax obligations.
If you have an AUSkey, you can check and update your details online at the ABR website abr.gov.au or you can phone them on 13 28 66 between 8.00am and 6.00pm (AEST),Monday to Friday.
