How Our Tax Refund Calculator Works
Whether you are a full-time employee, part-time, casual, or a sole trader, our free tax refund calculator makes it easy to understand your 2025 tax outcome in just a few straightforward steps:
-
Enter Your Income and Tax Withheld
Start by inputting your total gross annual income for the financial year and the amount of tax that has already been withheld from your pay. This is the foundation for calculating your taxable income.
-
View Your Estimated Tax Outcome
The calculator instantly applies the current tax scales and levies (like the Medicare Levy) to your figures. You'll immediately find out if you're on track for a tax refund (meaning you overpaid tax throughout the year) or if you have an amount to pay (meaning not enough tax was withheld).

Updated for 2025-2026: The Rates That Affect Your Refund
The integrity of our tool relies on current and valid data. Our Tax Return Calculator is updated in conjunction with the Australian Taxation Office (ATO) Pay As You Go (PAYG) schedules and incorporates the approved tax scales for the financial year starting July 1, 2025, and ending June 30, 2026.
In Australia, the system is progressive—the more you earn, the higher your tax rate. Our calculator factors in the updated brackets for the 2025-2026 period:
- 0% for income up to $18,200 (Tax-free threshold)
- 16% for income between $18,201 and $45,000
- 30% for income between $45,001 and $135,000
- 37% for income between $135,001 and $190,000
- 45% for income over $190,000 (Plus the Medicare Levy of typically 2%)
By using the correct rates, our tax refund calculator ensures your output is a true reflection of your potential tax outcome under current Australian law.
Refine Your Tax Return Estimate: Advanced Inputs for Precision
While basic figures provide a good starting point, including extra details will give you a much more precise tax return estimate. Use our advanced options in the Tax Calculator 2025 to factor in common items that significantly affect your final tax liability:
- Total Deductions: Include all known work-related expenses, charitable donations, and costs of managing tax affairs.
- Other Income: Include bank interest, investment income, or income from a second job.
- Reportable Amounts: Add reportable employer super contributions (RESC) or reportable fringe benefits (RFB).
- HELP/HECS: If you have an existing student loan balance, this will be factored into the required repayment amount.
For more accurate results and complete Tax compliance, our experts can guide you in correctly categorising deductions and offsets to ensure your return meets ATO standards.
Frequently Asked Questions
Your tax return is calculated by taking your total income and subtracting all eligible deductions and offsets to arrive at your taxable income. This figure is then taxed using Australia’s progressive tax rates (0% to 45% based on income brackets), plus the Medicare Levy (generally 2%). Finally, any tax you have already paid (or had withheld by your employer) is subtracted. If the tax paid is greater than your total tax liability, you receive a tax calculator tax refund. If it is less, you have tax payable.
