How Australian Income Tax Works
Taxable Income is your gross income minus eligible deductions such as work-related expenses, charitable donations, and self-education costs. The ATO applies marginal tax rates to each portion of your taxable income within each bracket.
Medicare Levy is an additional 2% tax on taxable income that contributes to Australia's universal healthcare system. Some low-income earners and specific groups may be exempt.
Low Income Tax Offset (LITO) reduces tax payable for low-income earners, providing up to $700. It phases out completely at $66,667 annual income.
