Public and multinational business three-tier model

Our model for PMB entities helps us understand the tax system in operation and guide our areas of focus for compliance.

Last updated 7 November 2025

The 5 pillars of compliance

We monitor the level of willing participation in the tax system through the OECD’s 4 pillars of tax compliance.

The three-tier model (3TM) is comprehensive and leverages the pillars of compliance to consider all areas of tax performance and the tax and super laws. This means that the model covers the different ways taxpayers interact with the tax and super systems.

Increasingly we are also focussing on third-party reporting as a 'fifth pillar' in its own right. Third-party reporting is reporting on the tax affairs of others. The modern tax system is increasingly relying on third-party data provided by large corporate groups. This has flow-on impacts for taxpayers of all sizes and how they interact with their tax obligations.

Taxpayer behaviours identified in the model are generally linked to one of the pillars of compliance:

  1. Registration: Are taxpayers correctly registered in the tax system?
  2. Lodgment: Are taxpayers lodging their forms on time?
  3. Correct reporting: Are taxpayers providing the right information in their forms?
  4. Payment: Are taxpayers paying their obligations on time?
  5. Third party reporting: Are taxpayers providing accurate and timely data for the ATO?

The 3 tiers and what they tell us

The model is made up of 3 tiers that drill down into the behaviours we observe for public and multinational business:

  • Tier 1: These are the major drivers of tax performance and non-performance for these taxpayers. These behaviours are what drives improvement or deterioration in the tax gap.
  • Tier 2: These are the visible events for Tier 1 behaviours. They can impact on us achieving improvements in tax performance or preventing deterioration in the system.
  • Tier 3: These are the specific focus areas for each Tier 2 event. This is where we intervene to address the behaviours.

How we use the 3TM in our decision making

By giving us a holistic view of taxpayer behaviours, the model:

The model allows us to provide transparency on where we are focussing our efforts to:

  • foster strong tax performance
  • prevent and address tax non-performance by public and multinational business.

How taxpayers can use the 3TM

Our justified trust assurance programs focus on assuring that the largest public and multinational businesses have paid the right amount of tax. These programs provide an important foundation for our levels of confidence about tax compliance across the various behaviours addressed by the 3TM.

Public and multinational businesses can use the model to consider their performance in the tax and super systems. Through improved understanding of our views on observed behaviours, taxpayers can:

  • gain insight into our focus areas and be prepared
  • address any potential areas of non-performance early.

Owing to wide ranging differences in business activities, models and structures, not all focus areas in the model will apply to every taxpayer. However, the model can help taxpayers understand where we are likely to direct our attention and at what intensity.

Whilst the 3TM covers the key drivers of tax performance there may be times where non-compliance is detected but is not covered by the model. We may choose to investigate the matter even though the matter is not currently reflected in the model.

The PMB three-tier model

For public and multinational businesses, we've identified 5 behaviours driving tax performance:

These behaviours are Tier 1 of the three-tier model. The following tables outline the events (Tier 2) and focus areas (Tier 3) for each behaviour.
