If you are a permanent migrant or temporary visitor to Australia you can apply for a TFN online at any time after entering Australia.
This option is available if you are a:
working holiday-maker
New Zealander (who is automatically granted a visa on arrival)
overseas student
person with a valid visa allowing you to stay in Australia indefinitely, and
person with a business visa.
To apply online, you need a valid passport or relevant travel documents and must be:
authorised to work in Australia by the Department of Immigration and Citizenship (DIAC) or have a valid overseas student visa
allowed to remain here indefinitely, and
in Australia when you lodge your application.
When you apply online you do not have to physically provide proof of identity documents for registration purposes. We will compare your personal and travel document details with DIAC’s records. When we validate your details, we will give you a receipt number.
