Tax refund vs tax return: what’s the difference?
Your tax return is the form you lodge with the ATO each year. Your tax refund is the money that comes back if you paid more tax than you owed. People use the terms interchangeably, so this tool works either way: it estimates both your refund and any amount owing for 2026–27 using current ATO rates.
How Australian tax refunds work
A tax refund isn’t free money, it’s your own money coming back. Through the year your employer withholds tax from each pay under the PAYG system, and that withholding is designed to land close to the tax you owe. So a big refund usually means one of two things happened: you had deductions that lowered your taxable income, or too much was withheld because your income varied or your employer didn’t have the full picture.
When you lodge your return, the ATO works out your real tax bill on your income after deductions, then compares it to what was withheld. If more was withheld than you owe, you get the difference back. If less was withheld, you have a bill to pay. Because withholding is meant to match your tax, the two main levers on the size of your refund are your deductions and any over-withholding, which is exactly what this calculator lets you model.
Common work-related deductions
Deductions are the biggest lever most people have over their refund. You can claim work-related costs you paid yourself and weren’t reimbursed for, as long as you have records. Some of the most common:
Work-from-home running costs
A fixed rate per hour worked from home, or the actual cost of electricity, internet and phone used for work.
Car and travel for work
Trips between work sites or to see clients (not your normal commute), logged by the cents-per-kilometre or logbook method.
Tools, equipment and tech
Items you buy for work, laptops, tools, protective gear, written off immediately or depreciated over time.
Self-education and courses
Study directly related to your current job, including course fees, textbooks and travel.
Union fees and subscriptions
Union or professional-association membership and subscriptions to work-related publications.
Uniforms and laundry
Compulsory or protective uniforms and the cost of cleaning them.
You can only claim what you spent and can substantiate. The ATO updates rules and rates over time, so verify what applies to you at ato.gov.au. This tool is a guide, not tax advice.
How to use this calculator
- Enter your annual taxable income, your gross income for the year, before deductions.
- Add up your work-related deductions and enter the total. Watch the refund figure move as you do.
- If you have your income statement, enter the tax withheld during the year for a sharper estimate. Leave it blank and we'll estimate it as the PAYG on your full income.
- Tick the HECS/HELP box if you have a study or training loan.
- Read your estimated refund (or bill), with tax owed and tax withheld broken out.
Frequently asked questions
How big will my tax refund be?
It depends on how much tax was withheld from your pay versus how much you owe once deductions are counted. If your employer withheld more than your final tax bill, which is common, especially with work-related deductions, the difference comes back as a refund. Enter your income, deductions and (if you have it) the tax withheld figure from your income statement above for a 2026–27 estimate.
Why do I get a tax refund?
Australia's PAYG system is designed so your employer withholds roughly the right amount of tax across the year. A refund usually happens when more was withheld than you owe, most often because you have work-related deductions that lower your taxable income, or because your income varied and too much was withheld. It's your own money coming back, not a bonus from the government.
What deductions can I claim?
You can claim work-related expenses you paid yourself and weren't reimbursed for, things like working-from-home running costs, work-related car and travel, tools and equipment, self-education tied to your current job, union fees, and compulsory or protective uniforms. You need records to back them up. This calculator lets you enter a total deductions figure to see how it changes your refund.
When do I lodge my tax return?
The Australian financial year runs 1 July to 30 June. If you lodge your own return, the deadline is 31 October. If you use a registered tax agent, you can often lodge later, but you generally need to be on the agent's books before 31 October. You can lodge online through myGov and the ATO, and pre-fill data is usually available from late July.
Does this include Medicare and HECS?
Yes. The tax owed figure includes the 2% Medicare levy (with the low-income reduction), and if you tick the HECS/HELP box it adds an estimated study-loan repayment based on the marginal system that applies from 1 July 2025. Untick 'private hospital cover' and it also adds the Medicare Levy Surcharge, an extra 1% to 1.5% for singles earning over $105,000 in 2026-27, charged on your whole income. Because the surcharge isn't withheld from your pay, it lands as a smaller refund or a bill. It doesn't model every offset (like LITO) or the family surcharge thresholds, so treat the result as a guide, not tax advice.
Can I use this as a tax return calculator?
Yes. A tax refund calculator and a tax return calculator do the same job: they estimate your outcome once you lodge. This tool estimates your 2026–27 refund or amount owing based on current ATO rates, so you can use it under either name.
How much tax will I get back if I earn $50,000 in Australia?
On a $50,000 salary in 2026–27, income tax is about $4,770 plus the 2% Medicare levy, roughly $5,770 in total. Whether you get money back depends on how much your employer withheld: if they withheld more than you owe, the difference comes back as your refund. Enter your withheld amount above for an estimate.
How much tax will I get back if I earn $80,000 in Australia?
On $80,000 in 2026–27, income tax is about $14,520 plus a $1,600 Medicare levy, around $16,120 in total. Your refund, or bill, is the difference between that and what was withheld from your pay. The calculator compares the two once you enter your details.
