Your average tax rate is 0.0% and your marginal tax rate is 15.2%. 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 $15.20, hence, your net pay will only increase by $84.80.
A $1,000 bonus will generate an extra $848 of net incomes. A $5,000 bonus will generate an extra $4,240 of net incomes.
