In Australia, your tax return is calculated by subtracting eligible deductions from your total income to determine your taxable income. This income is then taxed according to progressive rates: 0% for income up to $18,200; 16% for income between $18,201 and $45,000; 30% for income between $45,001 and $135,000; 37% for income between $135,001 and $190,000; and 45% for income over $190,000. Additional levies, such as the Medicare levy (usually 2%), along with any applicable rebates or offsets, also apply. The final tax payable is calculated by adding any additional taxes due and subtracting any pre-paid taxes or withheld amounts, resulting in either a refund if you’ve overpaid or a bill if you owe more.
