Tax File Number
A tax file number (TFN) is a unique number issued to individuals and organisations to help the Tax Office administer tax and other Australian Government systems. It’s one of your most important forms of identification in Australia. It’s yours for life and keeping it secure is a good defence against identity theft.
While it is not compulsory to quote a TFN without one you may:
- Pay more tax than necessary
- Not be able to get government benefits you are entitled to receive.
A TFN will also help you:
- Lodge a tax return
- Ask the Tax Office about your tax affairs
- Start or change jobs
- Limit the amount of tax you pay on interest or dividends earned if you have savings accounts or investments that earn income.
 |
Your TFN is valuable. Don’t share it with friends and don’t provide it on the internet when applying for work. Keep it secure. |
