If you make 13,200 KWD a year living in Kuwait, you will be taxed 1,386 KWD. That means that your net pay will be 11,814 KWD per year, or 985 KWD per month. Your average tax rate is 10.5% and your marginal tax rate is 10.5%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 KWD in your salary will be taxed 10.50 KWD, hence, your net pay will only increase by 89.50 KWD.
A 1,000 KWD bonus will generate an extra 895 KWD of net incomes. A 5,000 KWD bonus will generate an extra 4,475 KWD of net incomes.
