The Australian Taxation Office (ATO) says it received 250,000 tip-offs from the community about tax avoidance and other dishonest behaviours since July 1, 2019, with more than 47,000 in the 2023/24 financial year alone.
The ATO estimates there is a shortfall of around $16 billion in the tax take each year because of businesses doing things like cash jobs. It receives almost 1,000 messages every week from people who know or suspect tax evasion.
