Let us know if you or someone else hasn’t met their tax obligations.

Voluntary disclosures 

Our aim is to maximise voluntary compliance. We encourage individuals or businesses to tell us if they haven’t met their state tax obligations.

We treat voluntary disclosures more favourably, with significant penalty discounts, than when we identify non-compliance.

Tip-offs 

We follow up on cases where people fail to meet their tax or grant obligations. Penalties and legal action may result from our investigations.

You can tip us off about another person or business if you see non-compliance.

You can make an anonymous tip-off. Our privacy policy and secrecy provisions protect your details and the information you provide.

If you are submitting a tip-off and don’t know a detail that is required for the form, please write 'Unknown' in the text field.
