Top 500 findings report

What our findings report for the Top 500 tax performance program covers for 2024–25.

Published 27 November 2025

Top 500 program

The Top 500 tax performance program (Top 500 program) provides assurance to both government and the community that Australia’s wealthiest privately owned groups are paying the right amount of tax and will continue to do so into the future.

The program’s engagement model encourages Top 500 groups to proactively demonstrate their commitment to meeting tax and superannuation obligations. These groups are supported through tailored, one-on-one engagements that take a holistic approach to assurance, aligned with the 4 pillars of justified trust. The Top 500 program works with the Commercial deals program to ensure that all significant transactions undertaken by Top 500 groups are subject to comprehensive review and oversight.

Where groups within the Top 500 population choose not to engage collaboratively, we apply traditional assurance approaches, including reviews and audits, to ensure compliance.

Over the longer term, our ongoing engagement with large private groups that seek to comply is designed to:

  • prevent disputes through early engagement on significant transactions
  • build mutual trust
  • foster willing participation in the tax and superannuation systems.

This report provides our outcomes, observations and insights for the 2024–25 financial year. If you control or represent a Top 500 group, these findings will:

  • help you understand our approach to Top 500 engagements, including areas of focus to consider when reviewing your tax affairs and tax governance
  • increase your awareness of common tax issues
  • highlight practical steps Top 500 groups can take to demonstrate they are paying the right amount of tax, including strengthening tax governance, improving transparency, and proactively addressing known risk areas.
