While you do not need to have a TFN, it is to your advantage to have one. If you do not have a TFN, you may:  pay more tax than necessary, or  not be able to get government benefits you are entitled to receive. Only one TFN is issued to you for your lifetime. Once a TFN has been issued to you, there is no need to re- apply for one if your circumstances change – for example, if you move interstate, change jobs, change your name, have investments, or claim government benefits. How to apply for a TFN online The online TFN registration system will be available 24 hours a day, 7 days a week, via the Tax Office website (www.ato.gov.au). Where technical difficulties are experienced, such as computer down time, you will be advised to try again later. Alternatively, you will also have the option to download a paper version of the application to complete and submit by post, or in person. A Tax File Number is a 9-digit number that identifies you in Australia. Please check with your local HR before applying online.
