The purpose of the audit was to examine how efficiently and effectively the ATO managed its collection of outstanding tax debt. A framework for analysing the ATO's approach to collecting outstanding debt was established by the ANAO. This framework reflected five key criteria in the collection process as they apply to managing outstanding debt, namely:

• initiatives to promote timely payment;
• identification of outstanding debt;
• setting priorities for collecting outstanding debt;
• management of collection practices; and
• collection results.
