About the Australia Income Tax Calculator
Australia uses a progressive income tax system with resident rates under the tax-year 2025-26 rules modeled on this page ranging from 0% on the first $18,200 to 45% above $190,000. In addition to income tax, most Australians pay a 2% Medicare Levy, and the Medicare Levy Surcharge may apply if you do not have private hospital cover. This calculator uses a simplified MLS toggle, so treat that part as an estimate rather than a full ATO income-test model.
The Australian tax system includes several unique features. The tax-free threshold of $18,200 means low-income earners pay no income tax. HELP/HECS student loan repayments use the marginal system modeled on this page, and repayment income can include items this calculator does not ask for. Employers are also required to contribute superannuation (retirement savings) at the 12% rate used on this page.
This calculator computes a planning estimate of your Australian tax position including the resident brackets, Medicare Levy, simplified surcharge handling, HELP/HECS repayments, and super contributions. It provides fortnightly and monthly net pay estimates commonly used in Australian payroll calculations.
When This Page Helps
Australia's tax system with its tax-free threshold, Medicare Levy, HELP repayments, MLS tiers, and super contributions creates a complex calculation. This calculator combines those layers so you can estimate take-home pay, super contributions, and repayment obligations in one place while clearly marking the simplified parts.
How to Use the Inputs
- Enter your total annual gross income in Australian dollars
- Add any deductible expenses
- Set the superannuation guarantee rate to 12%
- Indicate if you have an outstanding HELP/HECS debt
- Select whether Medicare Levy Surcharge applies (no private health cover)
- Review your tax breakdown, effective rate, and fortnightly take-home
Formula used
Australian Tax Brackets (tax year 2025-26):
- $0–$18,200: 0%
- $18,201–$45,000: 16¢ per $1 over $18,200
- $45,001–$135,000: $4,288 + 30¢ per $1 over $45,000
- $135,001–$190,000: $31,288 + 37¢ per $1 over $135,000
- $190,001+: $51,638 + 45¢ per $1 over $190,000
Plus: Medicare Levy = 2% of taxable income
HELP/HECS repayment (tax year 2025-26 approximation):
- $0–$67,000: 0%
- $67,001–$125,000: 15c per $1 over $67,000
- $125,001–$179,285: $8,700 + 17c per $1 over $125,000
- $179,286+: 10% of repayment incomeExample Calculation
Result: $17,988 total tax
On $85,000: income tax $16,288 + Medicare Levy $1,700 = $17,988 total. Effective rate is 21.16%. Super contribution of $10,200 is not included in take-home but grows your retirement savings.
Tips & Best Practices
- The $18,200 tax-free threshold means part-time workers earning under this pay no tax
- Consider private health insurance to avoid the Medicare Levy Surcharge once you cross the MLS thresholds
- Salary sacrifice into super to reduce taxable income — super is taxed at only 15%
- HELP/HECS debts are indexed to CPI, not interest — voluntary repayments save money
- Check if you qualify for the Low Income Tax Offset (LITO) for additional savings
Tax Components
The calculator combines progressive income tax, the Medicare Levy, possible Medicare Levy Surcharge, HELP/HECS repayments, and superannuation settings so the output reflects the full payroll picture.
Planning Notes
Use the result to compare salary scenarios, then check whether deductions, surcharge rules, or HELP thresholds change the outcome.
Payroll Checks
Fortnightly and monthly views are useful when comparing payslips, but the annual figure is still the best place to verify the total tax position.

Methodology
This page applies the Australian resident 2025-26 income-tax brackets to taxable income, then layers on the 2% Medicare levy, a simplified Medicare Levy Surcharge toggle, HELP/HECS repayment estimates, and compulsory super guarantee contributions at the current 12% rate. It is a planning estimator rather than a full ATO return engine.
The worksheet does not reproduce the full adjusted taxable income rules for HELP/HECS, exact MLS income tests, or every residency edge case, so the result should be treated as an estimate only.

Frequently Asked Questions
The first $18,200 of income is tax-free for Australian residents. This means if you earn under $18,200, you pay no income tax.
The Medicare Levy is 2% of your taxable income that funds Australia's public health system (Medicare). Low-income earners may get a reduction or exemption.
Under the tax-year 2025-26 rules modeled on this page, HELP and other study loan repayments use the marginal system with a $67,000 minimum repayment income. This calculator approximates that using taxable income only, so the output is close but not a full ATO repayment-income calculation.
Super is compulsory retirement savings contributed by your employer at the 12% rate used on this page. Contributions are generally taxed at 15% within the super fund, lower than most marginal rates.
The official MLS uses income-for-MLS-purpose thresholds and rates of 1%, 1.25%, and 1.5% under the tax-year 2025-26 settings modeled on this page. This calculator uses a flat yes/no estimate, so it is only a planning shortcut.
These rates apply to Australian tax residents. Non-residents do not get the tax-free threshold and, under the tax-year 2025-26 foreign-resident schedule, rates start at 30% from the first dollar.
