Register a business name
You can register your business in your own name, or register a new name for your business. It is important to ensure that your chosen business name is not already in use by another company. I highly recommend exploring trademark options for your business, to ensure that other’s dont use the same name.
Obtain an ABN
You can apply for an ABN without much difficulty from the ATO website. You can also register for GST at the ATO website if you would like to, or you believe your business turnover will exceed $75,000
An ABN is required for invoicing purposes and should be requested as soon as possible after determining that you would like to start a business.
