The link below takes you to an Excel-based tool, which estimates the change in tax revenue when you modify the personal income tax system. The tool allows you to modify the tax brackets, the tax rates, and the indirect and company tax offset, and outputs an estimated change in revenue along with plots of the marginal tax rates and the average tax rates. Instructions are included.

This tool replaces the previous 'total personal taxable income contributed to each income band' table, which was created to enable users to perform the calculations that the tool will now perform automatically. The updated table can still be accessed within the tool.
