Tax File Number (TFN)

tax-file-numberGetting a Tax File Number (TFN) is required of all workers in Australia. A TFN is a 9-digit number that is issued by the Australia government only once in your lifetime. It is required for such things as lodging a tax return, applying for government financial assistance, employment, and for your superannuation fund.

When receiving a TFN for the first time, it will be issued within 28 days of submitting your application, but you can start using it right away.

TFN for migrants/international students/visitors

If you are permanent migrant or visiting temporarily, you must be in the country to apply. This includes working holiday candidates, New Zealanders, an overseas student allowed to work, and legitimate visa holders.


To apply for a TFN, you must have a valid passport or travel documents, have an Australian address, and be allowed to work in Australia or have a valid student visa. Because the government already has proof of your documentation from your original visa application, you do not have to physically show your identity documentation.

Applying for your TFN online

You can apply online at any time after entering Australia – there is no time restriction on doing this.

It takes about 20 minutes to complete the process. You can go to a public library or Internet cafe to register online if you do not have Internet access. When completed, you receive a receipt number which you can begin using immediately until you receive your letter in the post.

TFN updates

Once you have a TFN, you MUST keep your details up to date with the government.
