When to lodge and what to wait for
The 2025–2026 financial year ended on 30 June and lodgement opened on 1 July. Timing matters more than speed — most amended early returns are lodged before the ATO's pre-fill data has arrived.
- Early July — lodgement is open, but employer, bank and health-fund data is still arriving. Use this window to estimate your outcome and gather records — the tax return checklist covers what you need.
- 14 July —employers must finalise Single Touch Payroll reporting. Your income statement switches to ‘tax ready’ in myGov from mid-to-late July.
- Mid-to-late July onward — the safest lodgement window: pre-fill is complete and most myGov returns process within about two weeks of lodgement.
- 31 October —the deadline for lodging your own return. A registered tax agent can extend that, provided you're on their client list by 31 October.
The estimate above uses the 2025-26 tax rates and thresholds already configured, so you can check the likely result while you wait for pre-fill. Claiming working-from-home hours or car kilometres?

How your tax return estimate works
Why estimate before you lodge?
Most people lodge between July and October, but knowing the likely outcome earlier helps you plan cash flow, adjust PAYG withholding if you consistently owe, and time any deductible expense before 30 June. If you want a step-by-step prep list before you start, the tax return checklist covers what to gather. Lodging with ABN or sole-trader income as well? Estimate that side first with the ABN and sole trader tax calculator. If the result is moving because of private cover, follow up with the Medicare Levy Surcharge guide. A refund driven by a one-off payment usually traces back to bonus withholding — the bonus tax guide explains that reconciliation. If HECS/HELP is doing the work, the HECS/HELP repayment guide explains how the threshold and rates apply to your repayment income, and the HECS repayment calculator projects it across future years (ATO's compulsory repayments page is the source of truth for the year-by-year thresholds).
If one figure is moving your estimate more than the others, dig into it with the dedicated tools: the bonus tax calculator for end-of-year bonuses, the redundancy payout calculator for termination payments and their tax-free limit, the capital gains tax calculator for share or property sales, the land tax calculator for an investment property's deductible holding costs, and the salary sacrifice calculator to test pre-tax super contributions before 30 June — the super contributions guide covers concessional caps and the personal-deduction path. For what you can actually claim, check the ATO's work-related deductions guidance.

Key concepts
PAYG withholding
Tax deducted from each pay by your employer. The difference between what was withheld and what you actually owe determines your refund or amount owing — the Australian income tax guide explains how brackets, LITO and Medicare combine into that liability.
Low Income Tax Offset (LITO)
An automatic tax reduction for lower-income earners — applied after income tax is calculated, with the offset tapering out as taxable income rises. You don't need to claim it.
Medicare Levy & MLS
The standard 2% Medicare Levy funds public health. Without private hospital cover above the MLS threshold ($101,000 single for 2025-26), the Medicare Levy Surcharge (1%–1.5%) may also apply. The threshold adjusts when you switch financial years.
Deductions & offsets
Work-related deductions reduce taxable income directly. Tax offsets and franking credits reduce the tax owed after calculation, subject to caps.
This is an estimate, not a tax return
Your ATO notice of assessment may differ based on additional income sources, specific deduction rules, prior year offsets, private health insurance rebate adjustments, and full ATO processing. Always consult a registered tax agent for advice specific to your situation.

Tax Return Estimate FAQs
How is my tax return estimate calculated?
Your estimated outcome is the difference between the PAYG tax withheld from your pay and what you actually owe for the year. The calculator reaches that liability by subtracting deductions from your income, applying the selected year's ATO tax brackets with the Low Income Tax Offset included automatically — an offset many simple calculators omit — then adding the Medicare levy, Medicare Levy Surcharge where it applies, and HECS/HELP repayments if turned on. Tax offsets and franking credits reduce the income-tax line but cannot push it below zero. If more was withheld than the total liability, the difference is your refund; if less, it shows as a balance owing.
How long does a tax return take to process?
Most returns lodged through myGov are processed within about two weeks, with the refund landing in your bank account shortly after the notice of assessment issues. Paper returns and lodgements that need manual review take longer — typically 4 to 6 weeks. The estimate this calculator shows is what you would expect to see on your notice of assessment, before any offset against existing ATO debts.
When is the tax return due?
The deadline to lodge your own return is 31 October, covering the financial year that ended on 30 June. If you use a registered tax agent you generally have until 15 May of the following year, provided you were on the agent's client list by 31 October. Lodgement opens on 1 July, but returns lodged in the first weeks of July — before pre-fill data has arrived — are the ones most often amended later. Waiting until your income statement is marked 'tax ready' (usually mid-to-late July) is the safer window.
When should I lodge — and what is myGov pre-fill?
Pre-fill is the data the ATO loads into your return automatically: employer income reported through Single Touch Payroll, bank interest, dividends, private health cover and government payments. Employers have until 14 July to finalise their payroll reporting, so most income statements switch to 'tax ready' in myGov from mid-to-late July, and bank and fund data streams in across the month. Lodging before your income statement is tax ready means working from unfinalised figures — the most common reason early returns get amended. Check the status in ATO online services first, and use an estimate like this one in the meantime to see the likely outcome.
What's the difference between a tax return and a tax refund?
Your tax return is the form (and the underlying calculation) you lodge with the ATO each year to declare income, deductions and offsets. The tax refund is the outcome of that return when total tax withheld through the year exceeded your actual liability — the ATO pays the excess back. A return can also produce no refund, or a balance owing, if too little was withheld. This calculator estimates the outcome of your return — refund, square, or owing — before you lodge.
Why do I owe tax instead of getting a refund?
Owing tax usually means PAYG withholding through the year was less than your full liability. Common causes: a second job or side income, the tax-free threshold claimed at more than one employer, large untaxed amounts (interest, dividends, capital gains), a HECS/HELP debt without HECS withholding ticked, or losing the private hospital cover that prevents Medicare Levy Surcharge. Each of these appears as its own line in the estimate breakdown, so you can trace exactly which one is moving your result.
Why is my refund smaller than last year?
Refunds shrink when withholding moves closer to your true liability, or the liability itself rises. Common causes: a pay rise pushed more income into a higher bracket, your HECS/HELP repayment rate stepped up with income, interest or investment income grew without any extra tax withheld, you crossed the Medicare Levy Surcharge threshold without holding hospital cover, or last year's result included one-off deductions or offsets that didn't repeat. Comparing both years side by side with the financial year selector — same inputs, different year's rates — shows whether the change comes from the rates or from your own numbers.
What can I claim as a tax deduction?
Work-related expenses you paid yourself and weren't reimbursed for: working-from-home hours at the fixed rate of 70 cents per hour, work-related car travel at 88 cents per kilometre (up to 5,000 km per car per year), tools and equipment, self-education tied to your current role, union or professional fees, deductible donations to registered charities, income-protection insurance, personal super contributions you've claimed, and tax agent fees. Total work-related claims up to $300 can be made without written evidence; above $300 you need records, and every expense must relate to earning your income. Fixed-rate working-from-home claims are the exception: you need a record of your actual hours worked from home (a diary or timesheet) even when your total claim is under that threshold. The calculator's deduction fields apply these directly to taxable income.
Do I need to lodge a tax return in Australia?
Most residents need to lodge if they earned more than the tax-free threshold during the financial year, had tax withheld, ran a business, received Centrelink payments above set limits, or had a HECS/HELP debt with reportable income. If you earned less and had no withholding, you may only need to submit a non-lodgement advice through ATO online services.
What is PAYG tax withheld and where do I find it?
PAYG (Pay As You Go) withholding is the tax your employer deducted from each pay during the year. The total appears on your income statement in myGov (ATO online services) or on a payment summary from your employer once Single Touch Payroll is finalised — usually by mid-July. If you don't have the figure yet, tick the 'estimate' option and the calculator derives it from the selected year's ATO rates for your income level.
How does HECS/HELP affect my tax return?
If your repayment income (taxable income plus reportable fringe benefits, reportable employer super and net investment losses) is above the HECS/HELP threshold, the ATO applies a compulsory repayment as a percentage of that income on top of your normal tax. If your employer wasn't withholding extra for HECS, that repayment lands as a balance owing at lodgement. With HECS/HELP turned on, the repayment shows as its own line in the estimate so you can see what it adds before you lodge.
How does Medicare Levy Surcharge affect my estimate?
If your income exceeds the MLS threshold ($101,000 single for 2025-26 — the threshold varies by year) and you don't hold an appropriate level of private hospital cover, you may owe MLS of 1%–1.5% on top of the 2% Medicare levy. The surcharge appears as a separate line in the estimate; holding private hospital cover for the full year removes it, and a family threshold applies if your household situation qualifies.
Can I switch financial years to compare outcomes?
Yes. Use the financial year selector at the top of the input panel and your estimate updates instantly using the configured tax brackets, LITO thresholds, Medicare levy, MLS thresholds and HECS/HELP rates for that year. Useful for comparing this year's result against last year's, or modelling what a planned change would have looked like under previous rates.
How much tax will I get back if I earn $60,000?
On a $60,000 salary for 2025-26, total tax is about $9,888 — income tax after the Low Income Tax Offset plus the 2% Medicare levy, with the tax-free threshold claimed and no HECS debt. If your employer withheld the standard PAYG amount you land close to break-even: refunds come from deductions and offsets, not the salary itself. Claiming $2,000 of work-related deductions turns that into roughly $670 back. Work-related claims above $300 need written evidence.
How much tax will I get back if I earn $70,000?
On a $70,000 salary for 2025-26, total tax is about $13,188 including the 2% Medicare levy, with the tax-free threshold claimed and no HECS debt. With standard PAYG withholding the outcome is close to break-even, so the refund depends on what you claim: $2,000 of work-related deductions returns roughly $640 at this marginal rate. A HECS/HELP debt or a second job changes the picture — both show as separate lines in the estimate.
How much tax will I get back if I earn $100,000?
On a $100,000 salary for 2025-26, total tax is about $22,788 including the 2% Medicare levy, with the tax-free threshold claimed and no HECS debt. With standard PAYG withholding the outcome is close to square; $2,000 of deductions returns roughly $640 at this marginal rate. Once income exceeds the MLS threshold ($101,000 single for 2025-26) without private hospital cover, the Medicare Levy Surcharge adds a further line to the liability.
