An Australian Business Number (ABN) is a unique 11-digit identifier issued to businesses for tax and compliance purposes in Australia.
For example, a sole trader operating a small café must obtain an ABN to issue tax invoices and meet their tax obligations. Having an ABN also allows businesses to register for Goods and Services Tax (GST) if their turnover exceeds the threshold, facilitating smoother transactions with suppliers and customers.
The ABN helps streamline business operations by ensuring that all entities are easily identifiable within the Australian tax system.
