According to the ATO, you don’t need an ABN to work as a sole trader. You can use your TFN, and not all people are eligible for an ABN (when their income is below $75K). That being said, there are many benefits to setting yourself up properly with an ABN (if you are eligible). Having an ABN has benefits:
- You can avoid withholding tax
- You will be able to register for GST
- You can register a business name
- You can register for a .com.au domain name.
