Australian Tax Calculator:
Calculate my tax refund

Here’s how to calculate your 2025 tax refund

Lots of people are curious about their tax refund this year.

You can calculate an accurate tax refund estimate in a few minutes. The 2025 tax refund calculator inside Etax is the most accurate tax calculator available in Australia.

Etax automatically collects income and other details from the ATO to improve your refund estimate accuracy – and to make the process fast and simple for you. The calculator even automatically calculates the best work from home deduction claim based on your circumstances – you can read more details here about work from home deductions.

The Most Accurate Tax Calculator

At Etax, after you register and log in, then start a tax return, the tax refund calculator shows your tax refund estimate at the top of the screen.

Remember: Your refund estimate starts low, then it grows when you add details like work-related deductions. Etax helps you find all the deductions you should claim.

The tax refund calculator shows your ATO tax refund estimate. The more details you add to your tax return, the more accurate the tax calculator becomes…

It is accurate to the cent, based on the information you add to your return – and it updates as you go.

Etax automatically adds the latest tax cuts and tax rebates in your refund estimate, for 2025.

Each time you add a new detail to your return, the Etax re-calculates your tax estimate. This way, you can see how each number and each tax deduction affects your overall tax refund.

That’s not possible with most tax calculators!

How to use the tax return calculator and see your accurate tax refund estimate:

• Start your 2025 tax return. (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.

The Tax Return Calculator is a free part of the Etax online tax return (a paid tax agent service). The calculator provides an instant estimate of your tax refund (or payable).

When you complete and sign your tax return (most people finish in just minutes), next, our qualified accountants check your return, and look for suggestions about further deductions or adjustments that can boost your tax refund or prevent ATO trouble.

After trying it, most people use Etax for their tax return, because it is done from your home, affordable, convenient, and includes friendly support from real accountants, and lastly, no appointments needed. Etax is the top-rated tax service in Australia – you can read more at the Etax reviews page.

The best tax 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 add all of your real income details, the tax calculator may tell you an incorrect, higher refund than you will get from the ATO.

If you add a bunch of rough numbers or guesses, your refund estimate will only be a rough guess as well.

The ATO doesn’t like it if you submit fake or inflated numbers on your tax return. Remember, the ATO can see your income and even your bank accounts. They are not easily fooled, and you can end up paying back taxes plus ATO interest and extra penalties.

Etax helps you avoid that problem.

Inside your Etax return, we automatically complete parts of your tax return with correct numbers taken straight from your ATO records.

That means, better tax refunds and less chance of painful ATO troubles.

Plus, 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.

Why not use the basic ATO tax calculator?

For starters, the ATO’s job is to collect taxes, not help you get a better refund.

It is risky to rely on an over-simplified tax refund estimate. It’s even more risky to enter rough details and then count on an inaccurate tax refund estimate.

Also, using the ATO’s system, you don’t get any tips about tax deductions that can improve your tax refund.

A calculator that tells you the highest refund right now might make you feel good, but later if your real ATO tax refund is lower, ouch.

Some final (important) advice about your tax refund estimate

When you get a refund estimate, and lodge your return, usually you get your refund in 7-10 days.

Until you get your refund in your bank account, don’t spend any extra money, because the ATO can grab your tax refund unexpectedly.

For example, if you had an ATO debt many years ago, the ATO will commonly hide that debt, and they won’t tell you about it. But then, when they see you have a refund coming, they take your refund to pay an old debt that you forgot about, years ago. Not very friendly, right? However, if you use a tax agent like Etax, they help you make sense of what the ATO is doing and they can talk to the ATO for you.

It’s best to enter your details carefully, and get prefill help from Etax, so you’ll know how much to really expect from the ATO.
