What is the effective tax rate?

Your effective tax rate is the total tax you pay (income tax + Medicare levy + any surcharges + HECS repayments) divided by your total taxable income, expressed as a percentage. It represents the average rate of tax across all your income, which is always lower than your marginal tax rate (the rate on your last dollar earned).
