The quick answer
Your refund is the tax withheld from your pay, less the tax on your taxable income. On $90,000 with $20,500 withheld and $1,800 of deductions, the 2025-26 estimate is a refund of $1,488. With no deductions it is a refund of $912.
How the estimate is worked out
- 1
Enter your income for the year
Use the gross figure on your income statement, plus any other income you earned.
- 2
Enter the tax withheld
The total tax your employers took out of your pay across the year.
- 3
Enter your deductions
The work-related costs you paid for yourself and have a record of.

Read the result
A refund when more was withheld than you owe, or an amount to pay when less was.
The same example, line by line
| Income | $90,000 |
| Deductions | −$1,800 |
| Taxable income | $88,200 |
| Income tax and Medicare levy | $19,012 |
| Tax withheld from pay | −$20,500 |
| Estimated refund | $1,488 |
In that example the $1,800 of deductions changed the result by $576. That is the part you control: the income and the tax withheld are fixed by 30 June, but a deduction you have a record for still counts. The deduction finder lists what people in your job usually claim, and the occupation guides go through each one.

Tax refund estimates: common questions
How do I work out my tax refund in Australia?
Take your income for the year, subtract your deductions to get taxable income, work out the income tax and Medicare levy on that, then compare the total with the tax already withheld from your pay. If more was withheld than you owe, the difference is your refund. If less was withheld, the difference is the amount to pay.
Where do I find the tax withheld figure?
It is on your income statement, which your employer reports to the ATO and you can see in ATO online services through myGov. Before the statement is marked tax ready, the year-to-date tax on your final payslip for June is the closest figure.
How much does a $1,000 deduction add to a refund?
A deduction lowers your taxable income, so it is worth your marginal rate, not its full amount. On a taxable income taxed at 30 cents in the dollar plus the 2% Medicare levy, a $1,000 deduction changes the result by about $320. Type your own figures and the calculator shows exactly what your deductions change.
Why would my actual refund differ from this estimate?
The ATO works from your whole return. Items this estimate leaves out include the Medicare levy surcharge, tax offsets beyond the low income tax offset, bank interest, dividends, government payments, capital gains, and reportable super or fringe benefits in your study loan repayment income. A debt on your ATO account can also be taken out of a refund.
Does a refund estimate change if I have two jobs?
Add the income and the tax withheld from both jobs together. If you claimed the tax-free threshold from both employers, too little tax may have been withheld across the year, which is the most common reason a return shows an amount to pay.
Can I use this calculator if I am a sole trader?
For a quick view, yes: enter your business profit as income and any PAYG instalments you paid as tax withheld. It does not apply the small business income tax offset, so a sole trader with a profit will usually see a slightly better result on the real return.
Did you know?
The Medicare levy began at 1% of taxable income when Medicare launched in February 1984; it has since doubled to 2%, the last step taken on 1 July 2014.
Wikipedia: 'When Medicare was introduced by the Hawke Labor government in February 1984, it was accompanied by a Medicare levy to help fund it', set 'at 1% of personal taxable income', and 'From 1 July 2014 the Medicare levy rose from 1.5% to 2.0%'.
Source: Wikipedia — Income tax in Australia ↗Australian companies pay a flat 30% on profits — unless they are a 'base rate entity' with annual turnover up to $50 million, which pays 25%. Two rates, nothing in between.
Wikipedia: 'company tax is calculated at a flat rate of 30% (25% for small businesses)', with base rate entities having 'an annual turnover of $50 million giving a tax rate of 25%'. Income taxes are described as 'the most significant form of taxation in Australia'.
