If you make $40,000 a year living in Australia, you will be taxed $4,942. That means that your net pay will be $35,058 per year, or $2,922 per month. Your average tax rate is 12.4% and your marginal tax rate is 21.0%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of $100 in your salary will be taxed $21, hence, your net pay will only increase by $79.
A $1,000 bonus will generate an extra $790 of net incomes. A $5,000 bonus will generate an extra $3,950 of net incomes.
