How income tax works in Australia

Australia uses a progressive tax system, meaning different portions of your income are taxed at different rates. As your income increases, higher portions are taxed at higher rates rather than a single flat rate.

What affects your tax payable?

Understanding effective vs marginal tax rates

Your marginal tax rate is the rate applied to your last dollar of income, while your effective tax rate is the overall percentage of your income paid in tax. The effective rate is usually lower due to the progressive tax system.

To better understand how your income impacts financial decisions, you can estimate borrowing capacity with our mortgage calculator, or plan long-term wealth growth using the compound interest calculator.

Frequently asked questions

How is income tax calculated in Australia?

Income tax is calculated using progressive tax brackets, where different portions of your income are taxed at different rates.

What is the Medicare levy?

The Medicare levy is typically 2% of your income and helps fund Australia’s public healthcare system.

When do HECS repayments apply?

HECS/HELP repayments begin once your income exceeds a minimum threshold and are calculated as a percentage of your income.

Why is my effective tax rate lower than my marginal rate?

Because only part of your income is taxed at higher rates, your overall tax percentage is lower than your highest bracket.
