If you make 120 000 € a year living in Ireland, you will be taxed 48 911 €. That means that your net pay will be 71 089 € per year, or 5 924 € per month. Your average tax rate is 40.8% and your marginal tax rate is 52.0%. 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 52 €, hence, your net pay will only increase by 48 €.
A 1 000 € bonus will generate an extra 480 € of net incomes. A 5 000 € bonus will generate an extra 2 400 € of net incomes.
