Student Tax Calculator Australia: How Much Tax Do You Actually Pay?

If you're a student working part-time or casually in Australia, tax can feel confusing — but the good news is that most students pay little to no income tax. This guide explains exactly how tax works for students in FY 2025-26, what the tax-free threshold means for you, when HECS-HELP repayments kick in, and how to make sure you're not overpaying.

Do Students Pay Tax in Australia?

Yes — students are taxed just like any other worker in Australia. There's no special "student tax rate." You pay income tax based on the same FY 2025-26 tax brackets that apply to everyone.

However, because most students work part-time or casually and earn relatively low incomes, many end up paying very little tax — or even $0 — once offsets like the Low Income Tax Offset (LITO) are factored in.

These are marginal rates — only the income above each threshold is taxed at that rate. You can see the full calculation in our Income Tax Calculator.

The Tax-Free Threshold: Your Most Important Tool as a Student

The tax-free threshold means the first $18,200 of your annual income is completely free from income tax. On top of that, the Low Income Tax Offset (LITO) can reduce your tax bill by up to a further $700 if you earn below $37,500.

Combined, these mean that if you earn under roughly $23,000 in a year, you'll pay $0 in income tax after your tax return is lodged.

Take-Home Pay Examples for Common Student Incomes

Here's what students typically take home at different annual income levels in FY 2025-26. These figures assume an Australian resident who has claimed the tax-free threshold, with no HECS-HELP debt.

HECS-HELP: When Do Repayments Start?

If you're studying at university with a HECS-HELP loan, you don't need to repay anything while you're earning below the threshold. In FY 2025-26, repayments only kick in when your annual income reaches $67,000.

Under the new FY 2025-26 rules, HECS repayments are calculated on a marginal basis:

• $0 – $67,000: No repayment required
• $67,001 – $125,000: 15c for every dollar above $67,000
• $125,001 – $179,285: $8,700 + 17c for every dollar above $125,000
• $179,286+: 10% of total income

Most casual or part-time student workers earn well below $67,000, so HECS repayments won't affect your pay. If your income does exceed the threshold, use our HECS-HELP Repayment Calculator to see exactly how much extra will be deducted.

One important tip: if you have a HECS debt, you should declare this to your employer on your TFN declaration. That way, the right amount is withheld from each pay, and you won't face a surprise bill at tax time.

Medicare Levy: Do Students Have to Pay It?

The Medicare Levy is 2% of your taxable income and applies to most Australian taxpayers. However, low-income earners are protected by an exemption threshold.

In FY 2025-26:

• If you earn below $27,222, you pay no Medicare Levy.
• If you earn between $27,222 and $34,027, you pay a reduced (shaded-in) levy — the amount gradually increases until it reaches the full 2%.
• If you earn above $34,027, you pay the full 2%.

Most student workers — particularly those in casual or part-time retail, hospitality, or admin roles — earn under $27,222, so they pay no Medicare Levy at all. Learn more with our Medicare Levy Calculator.

Why Many Students Get a Tax Refund

One of the most common questions students ask is: "Why did I get money back at tax time?"

The answer is simple: your employer withholds tax from each pay based on an estimate of what you'll owe for the full year. If you worked fewer hours or earned less overall than expected, your employer may have withheld too much — and the ATO refunds the difference when you lodge your tax return.

Common reasons students receive refunds include:

• Working only part of the year (e.g., school holidays or semester breaks)
• Earning under the tax-free threshold overall, but tax was still withheld
• Having work-related deductions (uniforms, study materials where allowed, etc.)
• The LITO reducing your actual tax liability below what was withheld

This is why it's important to always lodge a tax return — even if you think you didn't earn enough to bother. You could be leaving a refund unclaimed.

Student Tax Tips: 5 Things You Need to Know

• Get a Tax File Number (TFN) before you start work. Without a TFN, your employer is required to withhold tax at the top rate (45%). Apply at the ATO website — it's free.
• Claim the tax-free threshold from your main job only. If you have multiple jobs, only one employer can apply the tax-free threshold to your pay. Let your secondary employer withhold at the higher rate, then reconcile at tax time.
• Declare your HECS-HELP debt to your employer. This ensures the correct amount is withheld. If you forget and your income exceeds $67,000, you could owe a lump sum when you lodge your return.
• Lodge your tax return by 31 October each year. For most students, this can be done online via myTax in myGov in under 30 minutes. The ATO pre-fills most of the information from your employer and the bank.
• Keep records of work-related expenses. If you buy tools, uniforms, or equipment specifically for your job, you may be able to claim a deduction. Study costs are generally not deductible unless the course is directly related to your current job — not a future one.
