Calculate Australian income tax with ATO brackets, Medicare Levy, HELP/HECS repayment, superannuation, and fortnightly take-home pay estimates.
Australia uses a progressive income tax system with rates ranging from 0% (on the first $18,200 tax-free threshold) to 45% on income over $180,000. The Australian Taxation Office (ATO) administers these rates, which are updated annually in the federal budget. In addition to income tax, most Australians pay a 2% Medicare Levy to fund the public healthcare system.
The Australian tax system includes several unique features. The tax-free threshold of $18,200 means low-income earners pay no income tax. The HELP/HECS student loan repayment system is income-contingent, with repayment rates increasing as income rises. Employers are also required to contribute superannuation (retirement savings) currently at 11.5% of ordinary time earnings.
This calculator computes your complete Australian tax position including all ATO brackets, Medicare Levy and surcharge, HELP/HECS repayments, and super contributions. It provides fortnightly and monthly net pay estimates commonly used in Australian payroll calculations. Check the example with realistic values before reporting.
Australia's tax system with its tax-free threshold, Medicare Levy, HELP repayments, and super contributions creates a complex calculation.

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.
HELP/HECS debts are repaid through the tax system once your income exceeds the minimum threshold ($51,550 for 2024-25). Repayment rates range from 1% to 10% based on income.
Super is compulsory retirement savings contributed by your employer at 11.5% (2024-25). Contributions are taxed at 15% within the super fund, lower than most marginal rates.
An additional 1-1.5% surcharge applies if you earn over $93,000 (single) and don't have private hospital cover. Getting private health insurance avoids this surcharge.
These rates apply to Australian tax residents. Non-residents don't receive the tax-free threshold and are taxed at 32.5% from the first dollar.
