TFN Help

Already have a TFN or have already started the process but something has gone wrong? The TFN Help section focuses on practical problems involving existing TFNs and submitted applications.

Find guidance on locating a TFN you already have, understanding what to do when correspondence has not arrived, dealing with common TFN issues and deciding which next step makes sense for your situation.

This section is about solving problems rather than explaining how to make a first application. For suspected scams, stolen information or concerns that someone has obtained your TFN, use the TFN Security section.

Preguntas frecuentes

What should I do if I cannot find my TFN?
Do not automatically apply for another TFN. First look at appropriate ways of locating your existing number or obtaining assistance with accessing it.
What if my TFN has not arrived yet?
The appropriate next step depends on when and how you applied. Processing estimates are not guarantees, so check the relevant guidance before assuming there is a problem.
Can I get another TFN if I lost my original one?
Losing the record of your number does not normally mean you need a completely new TFN.
What if information on my TFN application was incorrect?
The appropriate correction process depends on the information involved and the stage of the application. Follow current official guidance rather than submitting duplicate applications without checking.
