What is a tax file number (TFN)?

Your tax file number (TFN) is your personal reference number issued by the Australian Taxation Office (ATO). It is unique to you and cannot be used by anyone else, and you cannot use anyone else’s TFN.

If you have been offered a Commonwealth supported place (CSP) in your course and/or wish to use a HELP loan to defer your fees, you must submit your tax file number (TFN) on an electronic Commonwealth Assistance Form (eCAF) by the due date of the relevant study period.

If you don't have a TFN, please see How do I get a TFN?
