The best tax return calculator is only as accurate as the numbers you add (but Etax helps you get it right) Some websites and tax calculators give big, huge refund estimates, but they only give you rough numbers; they don’t collect enough detail to give you a proper estimate. For example, you must add correct information into the calculator about your residency and all of your income (including Centrelink, bank interest, etc.). If you don’t, the tax calculator may tell you a higher refund than you actually receive from the ATO. If you add a bunch of rough numbers or guesses, your refund estimate will be a rough guess as well. The ATO really doesn’t like it if you submit incorrect or inflated numbers on your tax return. They’re not easily fooled and you can end up paying back taxes plus ATO interest and extra penalties.
