If you intend you work and earn money in Australia, you need a Tax File Number (TFN).
This is a unique number issued by Australian Taxation Office (ATO) to individuals and organisations for identification and record-keeping purposes.
As a working individual, there are three ways you can apply for a TFN, depending on your circumstances.
1. If you are visiting and intend to work in Australia/ Migrating to Australia Permanently. The ATO together with the Department of Immigration and Citizenship (DIAC) has developed an online registration process that will enable permanent migrants and temporary visitors to Australia to apply for an individual TFN via internet if you have a visa that: (a) allows work rights; (b) allows permanent migration; (c) valid to stay in Australia indefinitely.
2. If you live outside Australia and receive rental income from an Australian property, business income from Australian interests or need to lodge an Australian tax return for any other reason. You can apply for a TFN using Tax file number – application or enquiry for individuals living outside Australia (NAT 2628). (a) If you are a member of an Australian superannuation fund; (b) You need to lodge an Australian income tax return to claim; (c) You want to apply for an Australian business number (ABN) and if applicable, another associated business account, such as goods and services tax (GST).
