Free Annual Income Tax Calculator

Income Tax Calculator

This free annual income tax calculator is up-to-date with ATO official formulae for the current tax year and can be downloaded as a spreadsheet for desktop use.

This is a simple spreadsheet calculator which enables the calculation of income tax plus Medicare Levy and LITO for taxable income on an annual basis. The spreadsheet has been updated to include rates up to 2017-18.

For your convenience this spreadsheet is unprotected, so you can change how it looks, and there’s an optional scratch pad area where you can tinker with offset values and quickly see the weekly/monthly/ annual pre-and post tax incomes.

This spreadsheet is suitable as an annual tax estimate and planning tool, but should not be relied on to reflect the legal precision of an official tax assessment.
 

 

For the calculation of employee (payroll) tax withholding deductions in a downloadable spreadsheet version see Tax Tables.

For other tax calculators, recommended is the ATO online calculator or this one here.

(N.B. Spreadsheet requires MS Excel Windows version.  Sorry – Apple/Mac versions are not currently supported.)
