To find your Australian Tax File Number (TFN), you have several options: 1. Online via myGov and ATO Online Services

• If you have a myGov account linked to the Australian Taxation Office (ATO), you can sign in and select the ATO service. Then choose "Find my TFN" to view your number

• If you don't have a myGov account, you can create one and link it to the ATO to access your TFN online

2. Check Your Documents
Your TFN may be found on:

• Income tax notice of assessment (NOA)
• Payment summaries or income statements from your employer
• Official letters from the ATO
• Superannuation account statements
• Old tax return paperwork or digital files
• Payslips

3. Contact the ATO Directly

• Call the ATO on 13 28 61 during business hours (8:00 am to 6:00 pm Monday to Friday) to request your TFN

• If your TFN is lost or stolen, notify the ATO immediately by calling their Client Identity Support Centre at 1800 467 033

4. Ask Your Registered Tax Agent or Accountant
If you have used a tax agent or accountant, they can provide your TFN

. Additional Notes:

• You only need to apply for a TFN once; it remains the same for life

• Protect your TFN to avoid misuse or identity theft

In summary, the fastest way to find your TFN is by logging into your myGov account linked to the ATO and selecting "Find my TFN." If you cannot access that, check your official documents or contact the ATO directly
