Top 1,000 Next Actions Program

Why we may engage with a large public and multinational company for further action.

Last updated 25 November 2025

Top 1,000 assurance review

The Top 1,000 Next Actions Program is part of the Tax Avoidance Taskforce.

We examine the tax affairs of Australia's largest 1,000 public and multinational companies that are not covered by the Top 100 program. These assurance reviews give us and the community confidence that large companies and super funds are paying the right amount of tax.

What is a next action

If we identify concerns about your income tax affairs in your Top 1,000 assurance review, we may refer you for further action.

A 'next action' is the investigation of identified compliance income tax risks. We set out the form of your engagement in the formal notification you receive. The engagement may be review or an audit.

How you're selected

The outcome of your assurance review will determine whether you are selected for a next action engagement.

You will be selected if:

  • you receive an overall low assurance
  • you have a red flag rating
  • we identify other material tax risks.

We will advise you if you are part of a next actions case pool, before a next action begins.

Getting an assurance report

After an assurance review, you will get an assurance report explaining our findings and noting where we expect you to make changes or act.

We encourage you to review your assurance report and address the issues we have identified.

Review our Top 1,000 guidance

We encourage you to review our Top 1,000 findings and other published guidance and consider this in combination with your assurance report.

We continue to update our guidance to make it easier for you to address our concerns.

See What we look for to obtain assurance.

If you're selected for a next action

If you are selected for a next action, you will receive a formal notification letter.

The formal notification letter will indicate the start date of the engagement and outline the scope of the engagement and next steps.

We will focus on the issues that are of the greatest concern to us, such as issues that received a red flag or low assurance rating in your assurance report.

How to prepare for a next action

Prepare the evidence to demonstrate you have addressed and resolved the issues noted in your assurance report, including documenting the steps you have taken.

If you have chosen not to adopt the recommendations in your assurance report, prepare your evidence supporting your position.

The better prepared you are, the more likely the next action engagement can be resolved within a shorter timeframe and you limit your penalty exposure.
