(This is an interactive calculator widget. Field labels, options, and deduction categories are unchanged from the earlier version of this page — same 39-item occupation dropdown and the same D1–D10 ATO deduction category codes.)
âš The duplicate deduction-code labeling flagged in the earlier version is still present, unchanged: both “Working from home” and “Other work expenses” are still labeled “D5” in this calculator's deduction fields.

How it works
Three steps to your tax return estimate

File your flight plan
Enter your gross income and total tax withheld — the two numbers sitting front and centre on your income statement.

Clear for landing
Like what you see? Register with Tax Falcon and a registered agent will get your actual refund lodged in about 10 minutes flat.
Why this estimate holds up
More than a guess dressed up as a number
Plenty of tax refund calculators just multiply and subtract. Here's what backs up this one.
ATO-aligned rates
Built on the individual income tax thresholds for the current financial year, updated whenever the ATO moves them.
AI-assisted deduction finder
Once you register, our system flags deductions people in your line of work commonly forget to claim.
Agent-reviewed, not just automated
A registered tax agent checks every return before it's lodged. This calculator is the estimate — not the final word.
Maximum refund guarantee
If a registered agent could have found you a bigger refund elsewhere, we'll credit you the difference.

Frequently asked questions
Tax return calculator FAQs
How do I calculate my tax refund with Tax Falcon's calculator?
Enter your gross income and the tax withheld from your payslips or income statement, and the calculator instantly estimates your refund using current ATO tax rates. Add your work-related deductions by category for a sharper tax return estimate.
How accurate is a free tax return calculator?
A tax return calculator gives you a solid ballpark, but it's only as accurate as the numbers you enter and how many parts of your situation it accounts for. Tax Falcon's calculator factors in itemised work-related deductions across the main ATO categories — but your final refund is confirmed once a registered tax agent reviews your actual return.
What do I need to estimate my tax return online?
You'll need your gross income for the financial year and the total tax withheld by your employer — both are on your income statement or final payslip. Adding your work-related deductions by category will sharpen your tax refund estimate further.
When can I lodge my 2025–26 tax return?
You can lodge your 2025–26 tax return from 1 July 2026, once the financial year ends on 30 June 2026. If you're lodging yourself, the deadline is 31 October 2026 — lodging through a registered tax agent like Tax Falcon can extend that deadline.
Why is my tax refund estimate different from what I actually get back?
Your final refund depends on details a calculator can't always capture — like private health cover, government payments, or the Medicare Levy Surcharge. That's why every Tax Falcon return gets checked by a registered tax agent before it's lodged, so your actual refund lines up with your estimate.

âš This “Arthur Sterling” byline link points to /about-us — the same mismatched path already flagged on the revised “How Tax Falcon Works” page, where it also conflicted with the About Tax Falcon page's own declared canonical URL, /about. This is now the second confirmed instance of the /about-us vs /about mismatch, on a second, different page — reinforcing that it's a real, repeated linking error rather than an isolated typo.
