Wondering if your tax strategies will pass the 2026 test? Stay informed with Cockatoo’s latest insights and make sure your financial moves are both clever and compliant.

In 2026, tax avoidance has become one of the hottest topics in Australian finance.

The days of flying under the radar are over. As the Treasurer recently put it, “Everyone needs to pay their fair share, and the ATO now has the tools to ensure they do.”
