how to get a tax file number

To get a Tax File Number (TFN) in Australia, you normally apply free through the Australian Taxation Office (ATO), either online (most common) or via form/post, and then receive the number by mail within a few weeks.

What a TFN Is

• A TFN is a unique 9‑digit number that identifies you for income tax, superannuation and some government services.

• You use it with employers, banks and when lodging your tax return, and without it you can be taxed at the highest rate.

Who Needs a TFN

• Anyone working in Australia (employees, casuals, contractors, many students) is expected to have a TFN so tax can be withheld correctly.

• You also typically need one to interact properly with the tax system as a resident, migrant worker, or international student.

Ways to Apply

1. Apply Online via ATO

• Go to the ATO’s “Apply for a TFN” section and choose the option that matches you (citizen, resident, foreign passport holder, etc.).

• Fill in the online form with your personal details (name, date of birth, Australian address) and your identity documents, such as passport and visa information.

2. Using myGov / myGovID (Common Path)

• Set up a myGovID app, entering your full name, date of birth and matching email, and strengthen it by verifying identity documents like passport, birth or citizenship certificate, driver licence or Medicare card.

• Once your myGovID is set up, sign in to myGov, connect myGovID when prompted, then select the option to apply online for your TFN and submit the application.

3. Apply via Post or In‑Person

• If you cannot apply fully online, you can complete a paper or hybrid application form (for example, initiated online then lodged at Australia Post) and provide original or certified identity documents as instructed.

• You mail the completed form to the address on the form or follow the booking and lodgement instructions (such as printing an application summary and taking it to an Australia Post outlet).

After You Apply

• TFNs are not usually issued instantly; they are sent to your Australian postal address, generally within about 14–28 days depending on the method.

• Once received, give the TFN to your employer as soon as possible (usually within 28 days) so you are not taxed at the highest rate.

Quick Forum‑Style Insight

• People on Australian forums often remind new workers that being asked for a TFN before a proper job offer can be a little unusual, so it is okay to double‑check what a potential employer is requesting.

• Commenters also point out that the official ATO page is the safest place to follow step‑by‑step instructions, rather than relying only on random advice.
