Frequently asked questions
Do you keep the numbers I enter?
No. The calculators run entirely in your browser. Nothing you enter is sent to us or saved, and no cookies are used by the calculators.
How accurate are the calculators?
They use the official ATO and state revenue office rates and thresholds, checked on the date shown on each page. They are estimates: your actual tax depends on your full tax return, and your state revenue office calculates the actual stamp duty.
