If you make 120 000 zł a year living in Poland, you will be taxed 36 605 zł. That means that your net pay will be 83 395 zł per year, or 6 950 zł per month. Your average tax rate is 30.5% and your marginal tax rate is 42.4%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 zł in your salary will be taxed 42.40 zł, hence, your net pay will only increase by 57.60 zł.
A 1 000 zł bonus will generate an extra 576 zł of net incomes. A 5 000 zł bonus will generate an extra 2 880 zł of net incomes.
