Did you know your employer also pays tax on your salary? It costs the employer 51 KWD to pay you 425 KWD. In other words, every time you spend 10 KWD of your hard-earned money, 2.30 KWD goes to the government.
Real tax rate
20.5%
So, with you and the employer both paying tax, what used to be a 11% tax rate now rises to 20.5%, meaning your real tax rate is actually 9.5% higher than what it seemed at first.
Summary
If you make 5,100 KWD a year living in Kuwait, you will be taxed 561 KWD. That means that your net pay will be 4,539 KWD per year, or 378 KWD per month. Your average tax rate is 11.0% and your marginal tax rate is 11.0%. 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 11 KWD, hence, your net pay will only increase by 89 KWD.
Bonus Example
A 1,000 KWD bonus will generate an extra 890 KWD of net incomes. A 5,000 KWD bonus will generate an extra 4,450 KWD of net incomes.
