How this calculator works
The calculator applies the ATO's individual income tax rates for 2026–27 to your gross income, subtracts your deductions, adds the 2% Medicare levy where it applies, and compares the result against the tax already withheld from your pay. If more was withheld than you owe, the difference is your estimated refund.
What it takes into account: the tax-free threshold ($18,200), the 2026–27 marginal rates, the Medicare levy, the low income tax offset (up to $700), and your HELP/HECS repayment income if you have a study loan.
What it can't see: occupation-specific deductions you haven't thought of, offsets that depend on your circumstances (private health, spouse details, zone offsets), capital gains, rental property schedules, or foreign income. That's usually where the difference between an estimate and your actual refund comes from — in either direction.

What you'll need for an accurate estimate
Your year-to-date gross income and tax withheld (from your final payslip or your income statement in myGov), any extra income — interest, dividends, side work — and a rough total of your work-related deductions. Two minutes of gathering gets you a much tighter estimate.
Why your actual refund can differ
Every year we lodge returns for people whose real refund beat the calculator — and some where it fell short. The usual reasons: deductions they didn't know their occupation could claim, income the calculator wasn't told about (bank interest is the classic — the ATO already knows about it), HELP repayments kicking in above the threshold, and Medicare levy surcharge for higher earners without private hospital cover.
A registered tax agent's job is to find the first kind and protect you from the second. Our average client takes about 20 minutes to lodge with us, online or in our Sydney office.
