Are you sorting through documents and realizing you need your Tax File Number (TFN) but have no idea where to find it? You’re not alone. Whether you’re starting a new job, lodging your tax return, or updating your records with the ATO, knowing how to locate your TFN is essential. Don’t panic — there are several quick ways to retrieve this important number, even if you’ve misplaced your paperwork.
What Is a Tax File Number (TFN)?
A Tax File Number (TFN) is a unique nine-digit number issued by the Australian Taxation Office (ATO) to identify you for tax and superannuation purposes. It’s crucial for:
- Lodging tax returns
- Starting new employment
- Opening bank accounts
- Applying for government benefits
Keeping your TFN secure and accessible is vital because it’s confidential and shouldn’t be shared carelessly.
Where to Find Your TFN
Here are the most common and fastest ways to find your existing TFN:
| Source | Details |
|---|---|
| ATO Online Services | Log in via your myGov account linked to the ATO here. |
| Tax Returns | Check previous tax returns, assessments, or payment summaries. |
| Superannuation Statements | Most super funds include your TFN in statements or online accounts. |
| Employment Documents | Look at past payslips or employment records provided by your employer. |
| Accountant or Tax Agent | If you use a tax agent, they will have your TFN on file. |
Logging into your myGov account is often the quickest and most direct way to access your TFN, especially if you’ve linked it to the ATO. If you haven’t linked the accounts yet, it’s a straightforward process and takes just a few minutes.
I Can’t Find My TFN — What Should I Do?
If none of the above options help, don’t worry. You can request your TFN from the ATO by:
- Calling 13 28 61 (for individuals)
- Providing proof of identity, such as your driver’s license, passport, or birth certificate
Alternatively, you can complete a Tax File Number Enquiry form, which requires submitting certified copies of identification documents.
Important: The ATO will never send your TFN via email or text for security reasons.
How About Lost or Forgotten TFNs?
Losing your TFN doesn’t mean you need to apply for a new one. Instead, follow these steps:
- Double-check documents like previous tax records or superannuation emails.
- Use ATO online via myGov to retrieve your TFN securely.
- Call the ATO and verify your identity to obtain it directly.
Protecting Your TFN
Since your Tax File Number is a gateway to your financial and taxation information, be sure to:
- Keep digital and paper copies secured.
- Never share it in public or non-secure channels.
- Notify the ATO immediately if you suspect identity theft or misuse.
Key Takeaways

- It can be found via myGov, your tax agent, past employment, or superannuation records.
