Australian Tax Return Calculator

Do you want to calculate your tax refund?

The calculator inside Etax.com.au is one of the most sophisticated and accurate tax return calculators available.

Some websites and tax return calculators just ask for your income and tax withheld. They cannot accurately predict what your tax refund will really be.

Quite simply, they don’t collect enough information about your tax return to give you an accurate estimate…

At Etax.com.au, after you register and log in, the tax refund calculator shows your tax refund estimate right at the top of the screen. It is accurate to the cent based on the information you add to your return.

Each time you add a new detail to your return, the tax return calculator updates your estimated refund based on the effect the new information has on your overall tax refund or payable.

This is done automatically and in real time, helping you to see how different items in your return can affect your refund.  That’s not possible with most tax calculators!

Why not use the ATO’s basic tax refund calculator?

The ATO’s online tax calculator is a basic program that calculates an approximate or ‘ball park’ refund. The ATO’s calculator does not properly account for the Medicare levy and may provide an estimate that’s higher than your actual refund.

It is risky to use simplified or over-inflated high tax refund estimates.They make you feel good at teh moment, but later if you’ve relied on that info and spent more than you should have… trouble.

Instead, use an accurate tax return calculator and enter all your details carefully, so you’ll know how much to expect from the ATO.


Etax.com.au (Australia’s favourite online tax return) includes a live tax calculator that updates automatically based on each piece of information you enter, ensuring an accurate, personalised tax refund estimate.

Please note, the Tax Return Calculator is a free element of the Etax.com.au online tax return. The calculator provides an estimate of your tax refund (or payable).

After you complete and sign your tax return (most people finish in just 15 minutes), our qualified accountants check your return, and make any suggestions regarding further deductions or errors. You will then receive an accountant-checked final estimate. If any details or claims have changed, your final estimate may differ from the automated tax return calculator’s estimate (but the final figure prior to lodgement will be the most accurate possible estimate).

To start using the tax return calculator, you need to register and start your online tax return.

There is no obligation to complete your return online, although most people find it is the best way to do a tax return, full-stop.

Remember: The sooner you lodge your tax return, the sooner you’ll get your refund!
