How to keep your TFN safe

Your TFN is an important part of confirming your identity when you start a new job, open bank accounts and apply for government benefits. It's also an important part of locating and keeping track of your super savings. Keep it secure – in the wrong hands, it could be used to commit fraud.

Only some people and organisations can ask for your TFN. The most common are:

  • The ATO, when discussing your tax records

  • some other Australian Government agencies – for example, the Department of Human Services (Centrelink) and the Child Support Agency

  • your employer after you start work

  • your Super Fund

  • Higher Education providers

  • Registered Tax agents, Solicitors and Accountants

  • your bank or other financial institutions.

Tips to keep your TFN safe

  • Don't carry your TFN in your purse or wallet or store it in your mobile phone.

  • Don't share it with friends (including on social networking websites).

  • Don't provide it in a job application or over the internet.

  • Give it to your employer only after you start working for them.

  • Make sure that any Tax Agent you use is registered – check the Tax Practitioners Board website at tpb.gov.au
