Keep your tax file number safe

Your tax file number (TFN) is a key part of your identity whilst you are in Australia. It is an important detail of your proof of identity when you start a new job, open bank accounts and apply for government benefits. Keep it secure.

Protect your identity by protecting all your personal details including your TFN. Keep your passwords and TFN safe and never record or store them in a manner which leaves them open to theft, such as in your purse or wallet.

Only certain people and organisations can ask for your TFN, the most common being:

• the Tax Office when discussing your tax records
• your employer after you start work
• your bank or other financial institutions
• Centrelink, and
• your superannuation fund.
