On 24 May 2010, Treasury released a paper entitled "Disparities in average tax rates", prepared by members of its Business Tax Division. Interestingly, the paper notes that the views in the paper are those of the authors and not necessarily those of the Australian Treasury.
The paper finds evidence that average tax rates vary considerably across industries. The evidence is found to be reasonably robust with external validation used to confirm results. The average tax rate is found to be relatively high in the finance & insurance industry and relatively low in the most capital-intensive industries, such as electricity, gas & water, and mining.
