What You'll Learn

Registration
The Australian Business Number (ABN) is an 11-digit identifier for businesses in Australia. It is free to register for an ABN through the Australian Government's Australian Business Register (ABR). The ABR is maintained by the Registrar of the ABR, who is also the Commissioner of Taxation. The ABN was introduced on 1 July 2000 as part of a major tax reform.
To register for an ABN, you must be running a business or other enterprise. Not everyone is entitled to an ABN, and you may face prosecution or criminal charges if you apply when you are not entitled. Before you register, ensure you have all the information about your business. You can apply for an ABN on the ABR website. If you provide all the necessary information, you will receive your ABN as soon as you complete your online application.
The 11-digit ABN is structured as a 9-digit identifier with two leading check digits. The ATO has publicised the formula for creating valid ABN checksums. In the case of companies, the ATO determines the ABN by using the company's Australian Company Number (ACN) to which the two-digit checksum is prefixed.
The ABR aims to review your application within 20 business days. If your application is successful, you will receive a letter within 14 days to confirm your ABN. If your application is unsuccessful, you will receive a refusal number and a letter within 14 days confirming the refusal and outlining the reasons and your options, including your review rights.
If you change your business structure, you may need to apply for a new ABN. You can cancel your ABN on the ABR website.

Structure
The Australian Business Number (ABN) is a unique 11-digit identifier issued by the Australian Business Register (ABR), which is operated by the Australian Taxation Office (ATO). The ABN is a single identification number that enables businesses in Australia to interact with various government departments and agencies. It is required for tax purposes and other business activities.
The structure of the ABN is an 11-digit number, with the first two digits being a checksum. The nature of the ABN algorithm means that any 9-digit number can be made into a valid ABN by adding the two-digit checksum. In the case of companies, the Australian Company Number (ACN) is used as the first nine digits, with the two-digit checksum added as a prefix.
The ABN is not a replacement for a tax file number, but it is necessary for businesses to make business transactions and be eligible for the Goods and Services Tax (GST). It is also often required when opening a business bank account in Australia. Additionally, having an ABN can increase the credibility of a business as it proves that it is registered and recognised by the Australian government.
The ABR is responsible for the ABN application process and maintains the information available through the ABN Lookup website. It is free to register for an ABN, and businesses can conduct any number of businesses or activities under the same ABN as long as they operate under the same structure. However, if the business structure changes, a new ABN may be required. The ABR provides guidance on updating ABN information and cancelling an ABN if necessary.
