The objective of the audit was to assess the effectiveness of the Australian Taxation Office’s administration of the personal services income regime.

The audit reviewed the Australian Taxation Office's administration of the payment of tax by non-residents. The audit objectives were to:

• provide Parliament with assurance about how efficiently and effectively the ATO administers the payment of tax in respect of non-residents;
• identify any scope for more effective and efficient administration of the function; and
• identify any opportunities for the cost-effective collection of additional revenue.

The purpose of the report was to report to the Parliament on how effectively and efficiently the Australian Taxation Office administers the Tax File Number System, and to identify opportunities for improvement of that system. The ANAO developed a methodological framework for the evaluation of the efficiency and effectiveness of the ATO's administration of the TFN system. The framework examined the TFN system; individuals and their TFNs; TFN withholding tax arrangements; and TFN information matching.

Taxation rulings are a key mechanism used by the Australian Taxation Office (ATO) to disseminate the Commissioner of Taxation's interpretative advice on Australian taxation law. The objective of the audit was to:

report to Parliament on the operation of the ATO's administration of taxation rulings (public, private and oral rulings); and where appropriate, make recommendations for improvements, having regard to considerations of: efficiency and effectiveness of the ATO's administration of the rulings system, particularly in relation to the achievement of the objectives set by Parliament for the rulings system; the ATO's systems' capacity to deliver consistency and fairness for taxpayers; and good corporate governance, including the control framework.

The objective of this audit was to the examine action taken by the ATO to improve TFN integrity, particularly through the implementation of the recommendations made in:Report No.37, taking into account any changed circumstances, or new administrative issues, affecting the implementation of those recommendations; and Numbers on the Run, taking into account that the Government has not formally responded to the report at this time.The audit also aimed to identify further opportunities for the ATO to improve the effectiveness and efficiency of the TFN system. The report of this audit is necessarily detailed as it considers each of the recommendations and the extent to which they have been implemented.

The objectives of this audit were to improve: the accountability of the Australian Taxation Office to Parliament and the Government by the provision of advice that follows up on the ATO's implementation of the previous ANAO Report; and on the recommendations of the then Joint Committee of Public Accounts arising from its consideration of that Report and the efficiency, effectiveness and equity of debt collection by the ATO.

The audit reviewed the High Wealth Individuals Taskforce, a comprehensive compliance program with the Australian Taxation Office. The objective of the audit was to examine and report on the management and operations of the taskforce. In doing so, the audit reviewed the Australian Taxation Office's own evaluation of the taskforce and assessed whether, and to what extent, the taskforce delivered the outcomes specified by the Government.
