How your tax return works

Throughout the year, your employer withholds tax from your pay based on how much they expect you'll owe. When you lodge your tax return, the ATO calculates your actual tax liability and compares it to what was withheld:

Refund — If more was withheld than you owe, you get the difference back
Amount owing — If less was withheld than you owe, you need to pay the difference
What affects your refund?

Deductions: Work-related expenses, working from home (70c/hr), self-education, donations and other eligible costs. For the 2025-26 return, $300 is a written-evidence exception, not a free deduction. If relevant work claims exceed $300, keep evidence for the full claim, subject to category-specific rules.

Multiple income sources: Each payer withholds as if they're your only income source, which can lead to under-withholding.

Tax offsets (private health insurance rebate etc.) reduce your tax payable directly — your actual refund may be higher if eligible.

Common reasons for a tax bill: multiple jobs, investment income with no tax withheld, capital gains, incorrect TFN declaration, HELP debt repayments not withheld.

Before you lodge — 5-minute checklist
Wait for pre-fill. Most employer income statements, bank interest and dividend data finalise mid-to-late July. Lodging before then risks needing an amendment.
Submitted your super notice of intent? If you made personal super contributions in 2025-26 and want a deduction, lodge your notice of intent to claim your super deduction before you lodge your return — the deduction is forfeited if the notice goes in after.
Gather your deductions. If relevant 2025-26 work claims exceed $300, written evidence is generally needed for the full claim, subject to specific exceptions. Use the WFH deductions calculator or the deductions action plan to see what you can claim.
Estimate your refund first. Run the tax refund estimator to see your expected outcome — including LITO, Medicare levy and HELP repayments — before you lodge.
Lodge by 31 October 2026. The self-lodgment deadline for the 2025-26 return is 31 October 2026. Using a registered tax agent may entitle you to a later date.
FAQ
How is a tax refund calculated?
Your refund is the difference between the tax withheld during the year (shown on your income statement) and your actual tax liability based on your taxable income. If you withheld more than you owe, you get a refund.
What deductions can I claim?
You can claim eligible expenses directly related to earning your income, including work-related travel, occupation-specific clothing, tools, self-education and working from home. For 2025-26, the $300 rule is a written-evidence exception, not an automatic deduction: if your relevant work claims exceed $300, you generally need written evidence for the full claim, subject to category-specific exceptions.
Why do I owe tax instead of getting a refund?
Common reasons include having multiple jobs (each employer withholds tax as if they're your only income), investment income without tax withheld, or your employer under-withholding based on incorrect information.
When will I get my refund?
Most refunds are processed within 2 weeks if you lodge online through myTax. Paper returns take longer. If the ATO needs to review your return, it may take additional time.
What if I can't pay my tax bill?
The ATO offers payment plans for people who can't pay their tax bill in full. Contact them early to avoid penalties. Interest applies to overdue amounts.
When can I lodge my 2025-26 tax return?
You can lodge your 2025-26 return from 1 July 2026. Most pre-fill data (employer income statements, bank interest, dividends) is finalised by mid-to-late July, so lodging late July onward reduces the chance of needing an amendment.
What changed for tax from 1 July 2026?
The 2026-27 financial year began on 1 July 2026: the second-bracket rate dropped from 16% to 15%, MLS income thresholds were indexed, and the enacted work-expense standard deduction commenced for eligible workers. Its statutory amount is the lesser of $1,000 and assessable labour income, reduced by relevant actual work deductions. These settings affect the 2026-27 return you'll lodge in 2027 — the return you lodge now is still assessed on 2025-26 rules.
Which tax year does this calculator use?
It defaults to 2025-26 — the return you lodge from 1 July 2026 — and applies resident rates, LITO, the Medicare family and exemption details you enter, and optional HELP repayments for the selected year. Use the year selector to switch to 2024-25 for a late or amended return, or 2026-27 to estimate the year in progress.
