  • Top 100 justified trust program

    Justified trust is a concept from the Organisation for Economic Cooperation and Development (OECD).

    We originally introduced the justified trust concept starting with the top 100 population in 2016.

    We complete justified trust reviews as part of the yearly pre-lodgment compliance review (PCR) and annual compliance arrangement (ACA) processes.

    In these reviews, we apply consistent rating categories to our overall level of assurance. We apply a high assurance rating where we have confidence that the taxpayer paid the right amount of tax for the period reviewed.

    Due to the size and complexity of taxpayers in the top 100 population, we expect that it may take some taxpayers a number of years to reach high assurance. We are working with each of the top 100 as part of the PCR and ACA processes to gain and maintain a high level of assurance. We will tailor future engagements to focus on new, unassured areas and changes.

    Where a top 100 taxpayer attains an overall high level of assurance under our justified trust program, it means we have confidence that they have complied with Australian income tax laws.

    In recognition of the level of trust we have in the reported tax outcomes of these taxpayers, we will tailor our future engagement approach to focus on maintaining our high level of confidence. This is known as the 'Monitoring and Maintenance' approachThis link opens in a new window and will apply to taxpayers for the two income years following an overall high assurance outcome. For Top 100 ACA taxpayers who have attained an overall high level of assurance, we will revert to an annual ACA review in accordance with the ACA terms of arrangement.
