How do I register for an Australian Business Number (ABN) as a sole trader?

To start as a sole trader in Australia, you typically need an Australian Business Number (ABN). You can apply for an ABN online through the Australian Business Register (ABR) website. Registration is free. You will need your individual Tax File Number (TFN) and details about your business activities. Most applications are processed immediately, and you'll receive your ABN on the spot. Having an ABN allows you to invoice clients, claim GST credits (if registered), and avoid having 'no ABN withholding' (47%) taken from your payments by other businesses. Remember that while you use your individual TFN for your tax return, the ABN identifies your business to the government and other entities.
