What is an ABN?

ABNs are unique 11-digit numbers that allows you to conduct a business in Australia. You will need to provide relevant identification details in order to acquire one. Furthermore, if you want to register a business name, an ABN is required. If you already have one for another business, you can not use it for your online business.

Do you need an ABN to Sell Online?

If you are selling goods/services online, you need to decide whether you are selling as a hobby or a business. In simple terms, if you are operating as a business and the main reason behind selling the goods/services is to make profit then you must have an ABN. You will need to display it on invoices and receipts you issue to your customers. Furthermore, GST is another point of consideration regarding whether you should register one. You are required to register for GST if your online sales/ business has a turnover of more than $75,000 a year (before GST). If you make sufficient turnover to register for GST, you will also need to register an ABN. If you hire employees, you will need to have an ABN in order to register for PAYG Withholding.

Alternatively, you can apply for your domain name using your Australian Company Number (ACN) or trademark number). If you don’t have an ABN, you can register for a domain, however you cannot use this website for commercial purposes.
