What is a Tax File Number?
Your Tax File Number (TFN) is a unique identifier issued by the Australian Taxation Office (ATO) that stays with you for life. It's essential for:
- Lodging tax returns
- Starting new employment
- Opening bank accounts
- Accessing government services
- Claiming tax-free thresholds
Quick Ways to Find Your Lost TFN
1. Check Your myGov Account
The fastest way to find your TFN is through your myGov account:
- Log in to myGov.gov.au
- Link to the ATO if not already connected
- Your TFN will be displayed on your ATO online services dashboard
- If you can't access myGov, you can recover your account using your email or mobile number
2. Look Through Your Documents
Your TFN appears on various documents you might have at home:
- Previous tax returns or notices of assessment
- Group certificates or payment summaries
- Bank account opening documents
- Superannuation statements
- Centrelink correspondence
3. Contact Your Employer or Previous Employers
Your current or former employers will have your TFN on file. Simply call their payroll or HR department and request it.
4. Check with Your Bank
If you provided your TFN when opening bank accounts, your bank can provide it to you upon request with proper identification.

The ATO provides guidance through ato.gov.au, the Small Business Support Line (13 28 66), and Online Services for individuals and businesses. For complex situations, a registered tax agent provides advice tailored to your specific circumstances and professional indemnity protection. You can verify agent registration at the TPB register at tpb.gov.au.
Most tax records must be kept for five years from the date of lodgement or the date the transaction occurred, whichever is later. Records must be in English or convertible to English and must be sufficient to explain the income and deductions in your return. The ATO can request records at any time during the retention period.
Consider a registered tax agent when your affairs involve multiple income sources, business activity, investment properties, capital gains, or overseas income. Agents extend your lodgement deadline, provide safe harbour protection, and take professional responsibility for the advice given. Verify registration at tpb.gov.au.
The failure to lodge penalty is based on penalty units ($313 per unit from 1 July 2023), accruing per 28-day period for late returns and BAS lodgements. Incorrect information penalties range from 25% to 75% of the tax shortfall depending on whether the behaviour was careless, reckless, or intentional. Proactive disclosure before an audit begins typically results in significantly reduced penalties.
Tax minimisation is the legal arrangement of your affairs to reduce tax — claiming all eligible deductions, using appropriate structures, and timing income and expenses. Tax avoidance involves arrangements that technically comply with the law but achieve outcomes parliament did not intend. The ATO can apply Part IVA anti-avoidance rules to cancel benefits from avoidance arrangements.
