USC (Universal Social Charge)
If you make 18 000 € a year living in Ireland, you will be taxed 480 €. That means that your net pay will be 17 520 € per year, or 1 460 € per month. Your average tax rate is 2.7% and your marginal tax rate is 47.2%. 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 47.20 €, hence, your net pay will only increase by 52.80 €.
A 1 000 € bonus will generate an extra 528 € of net incomes. A 5 000 € bonus will generate an extra 2 640 € of net incomes.
