Tax file number
It’s not compulsory to have a TFN, but if you don’t have one you may have more tax withheld than you need to, or you may not be able to receive certain government benefits.
Before you apply, you should understand why you may need a TFN.
If you are able to attend an interview at a participating Australia Post retail outlet, you can apply for a TFN on the web. Otherwise, you will need to complete the paper application form Tax file number – application or enquiry for individuals form (NAT 1432) and provide the necessary proof of identity documents.
If you are a non-resident of Australia for tax purposes, you need to understand when you might need a TFN. You can apply for a TFN using the form Tax file number – application or enquiry for an individual living outside Australia (NAT 2628) and providing the necessary proof of identity documents.
If you are a permanent migrant or temporary visitor to Australia, you can apply for a TFN online at any time after entering Australia.
When you have completed your application, you can post the form and your certified copies of your proof of identity documents to the address specified on the form. Do not send us your original proof of identity documents – documents you mail to us may not be returned to you. Alternatively, you can take your application form and your original proof of identity documents to your nearest Australian Taxation Office (ATO) shopfront.
