The Australian Business Number (ABN)

Business in Australia : my ABN

You have just created your own business in Australia and you don’t know whether the ABN is necessary for your company or not? Then have a look at this page!

What is an ABN?

The Australian Business Number (ABN) is the ID of your business. More precisely, it is a unique number which allows your business to be identified by the government and other businesses. This number is generally required on your invoices and other documents relating to sales. If you don’t have an ABN, other businesses may withhold 46.5% from any payment to you for tax purposes. Registering for an ABN is not compulsory but you will need one to get the GST.

Thanks to your ABN, you can:

– facilitate your administrative process,

– confirm your identity to others,

– avoid PAYG (pay as you go) tax on payments you receive,

– claim GST credits and energy grant credits,

– buy an Australian domain name.

Don’t hesitate to contact us if you need help to develop your business in Australia.
