A Tax File number which is often shortened to TFN is a unique ID number every Australian worker receives from the government. The TFN is used for an individual’s tax return, benefit payments and superannuation services.  Australians are also required to have a TFN in order to apply for an Australian Business Number (ABN) and to complete a bank account application.

Keeping Your TFN Safe

Your TFN consists of 9 digits and is unique to you, you should therefore never let anyone else use it. It is very important to keep your Tax File Number safe because if it ends up in the wrong hands it could potentially be used to commit fraud or identity theft in your name.

When do I need a Tax File Number?

Every employees in Australia is required to have a Tax File Number as soon as they commence working at any new job.

It is possible that your employer could tax you at a higher rate than you should be if you haven’t provided them with your TFN.

Tax File Number Declaration Form

Every time you commence working at a new job your employer will give you a Tax File Number Declaration Form to complete when you start. In this form you provide your employer with your TFN. The form also includes questions about your residency status, citizenship and other tax related questions. Your employer will apply the information provided in this form to work out how much tax you should pay.

Be sure you select ‘Yes’ to the question “Do you want to claim the tax-free threshold from the payer?”
