What we do with your information

We'll follow up on any information you give us about tax evasion or fraud.

Even if your information does not lead to immediate action, it's still important as it helps us:

  • understand industry trends and identify opportunities for things to go wrong
  • understand the way people think and act when they choose not to do the right thing
  • work out the best ways to deal with these issues.

Because of our tax secrecy obligations we cannot let you know the outcome of your reported information. Even though we cannot provide this to you, we appreciate the information you give us. 

Protecting your information

We take the security and privacy of your information seriously. You can choose not to identify yourself or to use a false name.

Sometimes we find that reports of tax evasion do not include all the information we need. If you give us your name and phone number, we can contact you for more information. If information in a report is incomplete, we may not be able to use it.

We'll do everything we can to hide your identity, but you'll need to be careful to leave out information that may accidentally identify you in your report.

We'll keep your details confidential unless we're required or authorised to release your details by law.

Our privacy policy also contains information about your rights.

Sharing information with other government agencies

Where the law allows, we may share your information with other government agencies if the issue you've raised is more appropriate for another agency to deal with.

If you do not want us to share this information with other agencies, clearly state this at the beginning of your report. This may stop us from taking the best course of action to deal with your issue.
