How we respond to identity theft
The way we respond to identity theft depends on the situation:
Someone has your TFN
If someone has your TFN, you need to tell us and we will check for any unusual or suspicious activity on your account.
If someone uses your TFN, we'll confirm and then correct the details in your account.
This may take longer for more complex tax affairs.
We will then discuss any further action taken with you.
Monitoring your tax and super account
If your TFN has been compromised, we can help protect your tax and super account by monitoring your records before automatic processing of any lodgments or claims.
If an activity looks suspicious, we may contact you to confirm the details before processing commences.
The security measures we apply will remain on your file until we determine that there is no further risk.
