The Australian Taxation Office (ATO) established a task force in 1996 to develop a greater understanding of the factors involved and to devise a coordinated approach in dealing with the cash economy. The objective of the performance audit was to report to Parliament on the ATO's progress in addressing the cash economy, including its monitoring and reporting of outcomes. The audit focused on the ATO's implementation of its Cash Economy Task Force recommendations in the light of the tax reform that has taken place over the last two years.
