Do you want to calculate your tax refund?
The tax refund calculator inside Etax.com.au is the most sophisticated and accurate tax calculator available in Australia.
Some websites and tax calculators just ask for your income and tax withheld. They can’t accurately predict your real ATO tax refund.
Quite simply, they don’t collect enough information about you, to give you an accurate tax refund estimate.
The Most Accurate Tax Calculator
At Etax, after you register and log in, then open any year’s new tax return, 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 – and it updates as you go.
Each time you add a new detail to your return, the tax refund calculator re-computes your tax estimate. You can see how each number and each tax deduction affects your overall tax refund.
This happens automatically and in real time, helping you see how different items in your return can affect your refund. That’s not possible with most tax calculators!

- Start your tax return and create your account. (Already have an account? Just click here to login).
- Enter your income in the relevant fields.
- As you go, watch the top part of your return – your estimate is right there.
Next, go ahead and add more details like income or deductions. Keep an eye on the calculator; your tax refund estimate changes with each new item you add to your return. The Etax system re-calculates your refund estimate based on the latest details you’ve entered.

…plus you can finish your tax return in minutes, or save it all for later.
Please note, the Tax Return Calculator is a free element of the Etax online tax return (a paid tax agent service). The calculator provides an instant estimate of your tax refund (or payable).
If you decide to complete and sign your tax return (most people finish in just minutes), our qualified accountants check your return, and make any suggestions for further deductions or adjustments that can boost your tax refund or prevent ATO trouble.
If you just want to try the calculator, you are not obligated to sign and pay for a tax return.
But after trying it, most people use Etax for their tax return, because it is affordable, convenient, and includes friendly support from accountants with no appointments needed.
Etax Accountants is Australia’s most popular online tax agent and has helped Australians with online tax returns since 1998. The online tax return is updated every year based on your feedback.
The best tax calculator is only as accurate as the numbers you add (but Etax helps you get it right)
Your tax refund estimate updates based on the numbers you enter and the answers you provide to basic questions.
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 knows more about your finances than you would like to think. They know about your income, your bank accounts, credit cards, Centrelink, child support, overseas accounts and earnings – almost everything. Really.
And if the numbers on your tax return are not correct, the ATO really doesn’t like that. The ATO is not easily fooled and if you try, you can end up paying back taxes plus ATO interest and extra penalties.
Etax can help you avoid that problem.
Because inside your Etax return, you can get prefill suggestions (which means, automatically complete parts of your tax return with correct numbers taken straight from the ATO).
And after you finish your tax return, a friendly accountant (who’s on your side) will check your return before it is lodged to the ATO. That means, better tax refunds and less chance of painful ATO troubles.
Why not use the basic ATO tax calculator?
The ATO’s online tax calculator gives an approximate or ‘ballpark’ refund estimate. 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 rely on an over-simplified tax refund estimate and even more risky to enter rough details then count on a tax refund estimate.
A calculator that tells you a higher refund now might make you feel good today, but later when your real ATO refund is lower, ouch.
It’s best to use a calculator like Etax that tells you an accurate refund estimate, 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.

To start using the tax calculator, just register and start your online tax return. The more details you add about income and deductions, the more accurate your tax calculator will be.
Remember: The sooner you lodge your tax return, the sooner you’ll get your refund!
