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 Layman’s Terms, in Australia an ABN is not required when your business turnover is less than $75,000/year, but highly recommended.

A further consideration consideration is also GST. 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.

Selling as 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. A business will often sell products with the intention of making a profit and generating repeat sales over an extended period of time to name a few.

Selling as a Hobby

Often times if you are not paying for an online shop/website, making one off sales (eg: second hand clothing) or not selling to make a profit to name a few. You would be classed as selling as a hobby. Especially if you do not have the intention of transforming your online store into a long term commercially viable business.

I’m Unsure If I’m Selling as a Business or Hobby

If you answer “yes” to the following questions, devised by the Australian Taxation Office (ATO) then you are most likely closer to selling as a business than a hobby:

  • Did you set up your online store with the intention of becoming a business?
  • Do you pay for your online selling presence?
  • Is your main intention to make profit?
  • Do you make repeat or regular sales?
  • If you make the items you sell online, do you charge more than they cost you to make?
  • Do you manage your online selling activity as if it were a business?
  • Is what you are selling online similar or the same as what might be sold in a “brick-and-mortar” business?
