I’ve just watched NSW Greens MP Cate Faehrmann making the claim that Australian miners pay the lowest corporate income tax amongst Australian industry. But that simply false. Last year I calculated the average tax rates for Australian industries using ATO data.
In order to gain some appreciation for how the average effective tax rate for mining has varied over time I calculated the average effective tax rates for all industries and the corporate sector as a whole. The data are calculated from various issues of ATO taxation statistics for each industry, and each year from 2000-01.
I then calculated the standard deviation of average effective tax rates across the industries. The average effective tax rate for All Industries is graphed and plus and minus one standard deviation from the average is graphed too. Results are shown in Figure 3. Also included is the average effective tax rate for the mining industry. As can be seen, the mining industry has a higher average effective tax rate than the Australian average. Indeed, it has always been above the average plus one standard deviation of All industries.
