Tax File Number (TFN) Application in Australia
Get Your Tax File Number and Simplify Your Financial Future
A step-by-step guide to applying for your TFN and managing your taxes, earnings, and government services in Australia.
A Tax File Number (TFN) is a personal and unique identifier issued by the Australian Taxation Office (ATO). It plays a vital role in managing your taxes, accessing government services, and ensuring that your financial dealings in Australia run smoothly. Whether you’re an Australian resident, an overseas worker, or a foreign investor, applying for a TFN is an essential first step for handling your financial obligations.
How to Apply

Begin by visiting the official Australian Taxation Office (ATO) website, where you’ll find detailed instructions on how to apply for a TFN. The online application system is available 24/7, making it easy to apply from anywhere at any time.
Follow the simple step-by-step instructions to fill out the application form. Make sure all your details, such as your name, date of birth, and contact information, are entered accurately to avoid any processing delays.
As part of your application, you will need to submit identification documents. These typically include proof of identity, such as a passport, birth certificate, or other official documents, depending on your citizenship or residency status. For Australian citizens, this process is straightforward and can be completed online.
If you’re applying as a foreign resident, additional identity verification is required. After submitting the online form, you will need to visit an Australia Post outlet, or alternatively, if you’re abroad, an Australian embassy or consulate. There, you will provide original documents to verify your identity and complete the application process.
What You Can Do with This Number
A Tax File Number (TFN) is essential for managing your taxes and accessing key financial and legal benefits in Australia. It’s required for filing tax returns, opening a bank account, and applying for government services like Medicare and Centrelink. A TFN ensures you’re taxed correctly on your earnings and is necessary for legal employment if you’re a temporary resident or on a working visa. It also helps track your superannuation contributions for retirement.
