A Tax File Number (TFN) is a unique nine-digit number issued by the Australian Taxation Office (ATO) that serves as an individual's or business's unique identifier for tax and superannuation purposes. Applying for a TFN is essential for lodging tax returns, starting or changing jobs, applying for government benefits, and managing other tax-related activities.
How to Apply for a Tax File Number
- Australian citizens aged 15 years or older with an Australian passport can apply online using myGovID, a secure digital identity platform.
- Applications can also be made in person at Services Australia centers or participating Australia Post offices by completing the paper TFN application form and providing original proof of identity documents.
- For those unable to apply online or in person, applications can be submitted by post with certified copies of identity documents.
- Once the application is processed, the TFN is mailed to the applicant's address, usually within 28 days.
Eligibility and Required Documents
- Applicants must be at least 15 years old to apply online.
- Proof of identity documents are required, such as an Australian passport or other accepted Australian identity documents.
- Permanent migrants, temporary visitors, and residents have specific pathways and requirements for TFN applications.
Uses of a TFN
- Lodging tax returns
- Starting or changing jobs
- Applying for government support payments such as Family Tax Benefit or HECS-HELP
- Applying for an Australian Business Number (ABN) for sole traders
- Managing investment income and PAYG withholding tax
A TFN is issued for life and remains the same even if an individual's circumstances change, such as moving interstate or changing names. It is important to keep the TFN confidential to prevent identity fraud.
