In this series, we review a range of common questions we receive regarding when it is appropriate to register for an ABN. A popular question surrounds invoicing, and the essentials to include on a typical tax invoice.

What is an ABN?

An Australian Business Number (ABN) is the unique 11-digit number that is used to identify your business to the community and the government. An ABN allows your business to register for GST and to be endorsed as a deductible gift recipient or an income exempt charity. If you do not already have one, you can register for an ABN here.

Can I use the same ABN for more than one business?

Yes, you are able to conduct any number of businesses utilising the same ABN. However, the businesses must all operate under the same business structure. If you are wishing to start a business that operates under a different business structure, you will need to obtain a new ABN for that business.

What business structure am I using?

You will need to be aware of which business structure your business is operating under, so you know whether a new ABN is required. This is significant as obligations vary with each business structure, such as tax liabilities, asset protection and cost. The most common types are sole trader, company, partnership and trust. Learn more about the differences, advantages and disadvantages of each structure.
