A company tax rate based on profitability return, or as more commonly expressed, a resource rent taxation scheme has been intro- duced at various stages in the past by both Australian state and commonwealth governments._x000D_
At present a number of overseas countries are applying this form of legislation to the taxing of sections of their mining industries. Within this study, ways in which this type of tax has been used are examined. The form in which the tax can be applied varies. 1. It can be selectively or universally applied._x000D_
2. The base on which economic return is calculated can be selected in a number of ways. 3. It can start operating only when high profit levels exist, or alternatively be the basis of a total taxation scheme._x000D_
The implication for the Australian mining industry of the introduction of different types of resource rent taxation schemes is assessed within the context of previously enacted systems.
