What is a TFN?

A Tax File Number or TFN is your personal reference number that connects you to the tax and super system.
The TFN you’re given will be yours for life. It’s an important part of your tax and super records, as well as your identity.
Without a TFN you pay more tax and will only have limited access to government services.

Where can I find my TFN?

Or you can call the ATO, they will be able to help you locate your TFN.
Student Super is authorised under the Superannuation Industry (Supervision) Act 1993 to collect, use and disclose your Tax File Number (TFN). By providing your TFN, you give Student Super permission to use your TFN for superannuation purposes, which includes creating and administering your account and actioning your rollover requests. It is not compulsory to tell us your TFN, however if you don’t do so, your before-tax contributions and withdrawals are taxed at a higher rate and we can’t accept after-tax contributions from you, and we will not be able to help you find your existing and lost super.
