As well as the proof of identity document requirements we specify above, we may ask you to send us other documents (for example, proof of income). What we need depends on your reason for applying for a TFN. We will tell you which documents you must send at question 10.
We will only accept original or certified copies of your proof of income documents. If you don’t want to mail important documents, you can have them photocopied and certified as true and correct by any of the following:
barrister
judge
Justice of the Peace, or
solicitor.
