Where can I find my TFN?

Here are some places to check when searching for your TFN:
  • Login to your myGov account
  • Payment summaries from your employer
  • Lodged income tax returns (this is would be from the ATO)
  • Previous super statements
  • Ask your accountant
Or you can call the ATO, they will be able to help you locate your TFN.
By providing your TFN, you give Professional Superannuation Management Pty Ltd, the Trustee and the Fund Administrator permission to use your TFN for superannuation purposes, which includes creating and administering your account, searching for lost, active or inactive super accounts in your name, and actioning your rollover requests. It’s 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. We also can’t accept after-tax contributions from you, and our '<a href="/find-or-combine" target="_blank">Find or combine my super</a>' feature will not be able to help you find your existing and lost super.
