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.
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.
For the calculation of employee (payroll) tax withholding deductions in a downloadable spreadsheet version see Tax Tables.
(N.B. Spreadsheet requires MS Excel Windows version. Sorry – Apple/Mac versions are not currently supported.)
To get the download simply email the words “tax calculator” to atotaxrates(at)fastmail.com. You will be immediately emailed your download link.
