Applying for a TFN at a participating Australia Post retail outlet
If you are an Australian citizen over 15 with an Australian passport, you can apply for a TFN online using a Digital ID or myGovID. However, if you do not have an Australian passport or are under 15, you will need to use one of the other application options, such as applying at a participating Australia Post retail outlet.
To apply at Australia Post, you will first need to complete the online form on the Australian Tax Office's website. Make sure to use a browser other than Internet Explorer, as the form is not supported by it. You may need your Australian or international passport for identification. Print the application summary, which will include your application reference number.
Next, find a participating Australia Post retail outlet near you. Only selected Post Offices accept TFN applications, so be sure to check this before you go. You will then need to attend an interview at the participating Australia Post outlet within 30 days of completing your online form. Bring your application summary and current original proof of identity documents to the interview. Acceptable identity documents include an Australian or international passport, a birth certificate, or an ImmiCard. If your documents are in a name different from the one on your application, you must also provide a document explaining the name change, such as a marriage certificate. If your documents are not in English, you must provide a written translation certified by an authorised translation service.
Finally, sign your application at the interview to complete your TFN application. You should receive your TFN within 28 days of your interview. The Australian Taxation Office (ATO) will mail your TFN to the postal address on your application.

Applying for a TFN as a non-Australian resident
If you are a non-Australian resident, you can still apply for a TFN. The application process will depend on your residency status, identity documents, and whether or not you are in Australia. Here is a step-by-step guide on how to apply for a TFN as a non-Australian resident:
- Determine your eligibility: To apply for a TFN, you must meet one of the following conditions: you are a foreign passport holder, a permanent migrant, or a temporary visitor with work rights in Australia. New Zealanders are automatically granted a visa upon arrival in Australia.
- Choose your application method: There are two main ways to apply: online or by paper form. The online method is faster, but not everyone is eligible. Foreign passport holders, permanent migrants, and temporary visitors located in Australia with work rights can apply online using the Individual Auto Registration (IAR) system.
- Online application process: If you are eligible for the online application, go to the Australian Taxation Office (ATO) website and complete the online form. You will need to provide your Australian postal address, as your TFN will be posted to this address. The processing time is up to 28 days.
- Paper application process: If you are not eligible for the online application, you will need to use the paper TFN application form for people living outside Australia. This form can be obtained from the ATO Publication Ordering Service, either online or by phone. Complete the form and send it, along with certified copies of your current original proof of identity documents, to the address provided.
- Application through Australia Post: Another option for applying for a TFN is through a participating Australia Post retail outlet. You will need to complete the online form and then present your current identity documents at the retail outlet within 30 days. You will need to attend an interview, sign your application, and your TFN will be processed within 28 days.
- Application through Services Australia: If you are a Centrelink customer, you can apply in person at a Services Australia service centre. You will need to complete a paper TFN application form and provide original proof of identity documents. Aboriginal and Torres Strait Islander people who cannot provide enough identity documents for other application methods can use this option.
Remember, it is free to apply for a TFN as a non-Australian resident. Keep your application reference number handy, and if you haven't received your TFN notification letter within 28 days, follow up with the Australian Taxation Office.
