How to complete your TFN application form
Section A: Applicant information
The answers to the questions in this section will help us establish whether you are already on our records or not.
Definition of spouse
A spouse includes another person (of any sex):
- you are legally married to
- you are in a relationship with and is registered under a prescribed state or territory law
- although not legally married to you, lives with you on a genuine domestic basis in a relationship as a couple.
Section B: Address details
Your TFN will be sent to the postal address you provide. This could be your home address, your post office box, or your registered tax agent’s postal address.
We may use these details to send notices and correspondence about your taxation affairs.
Section C: Residency details
To understand your tax situation, you must first work out whether you are an Australian resident for tax purposes.
Generally, we consider you to be an Australian resident for tax purposes if you:
- have always lived in Australia or you have come to Australia and now live here permanently
- are an overseas student doing a course that takes more than 6 months to complete
- have been in Australia continuously for 6 months or more, and for most of that time you worked in the one job and lived in the same place
- will be or have been in Australia for more than half of the financial year (unless your usual home is overseas and you do not intend to live in Australia).
If you go overseas temporarily and don't set up a permanent home in another country, you may continue to be treated as an Australian resident for tax purposes.
The criteria we use to work out your residency status for tax purposes are not the same as those used by other Australian agencies for other purposes, such as immigration.
To check your Australian residency status for tax purposes, see Work out your tax residency.

Your TFN and keeping it safe
A TFN is a unique number we issue to individuals. It is an important part of your tax and superannuation records as well as your identity. It is also an important part of locating and keeping track of your super savings.
In the wrong hands, your TFN could be used to commit fraud, so keep it safe. Make sure you protect your identity by keeping all your personal details, including your TFN, secure.
We only issue one TFN to you during your lifetime, even if you change jobs, change your name, or move.
To find out more about how to protect your TFN and avoid identity crime, refer to Protect your information.
If you've lost your TFN
If you've lost your TFN or aren't sure you have one, check all your correspondence from us, or contact your registered tax agent.
If you still can't find your TFN, go to Lost or stolen TFN.
