Did you know your employer also pays tax on your salary? It costs the employer 330 KWD to pay you 21,130 KWD. In other words, every time you spend 10 KWD of your hard-earned money, 0.28 KWD goes to the government.
Real tax rate
2.8%
So, with you and the employer both paying tax, what used to be a 1.3% tax rate now rises to 2.8%, meaning your real tax rate is actually 1.5% higher than what it seemed at first.
Summary
If you make 253,560 KWD a year living in Kuwait, you will be taxed 3,255 KWD. That means that your net pay will be 250,305 KWD per year, or 20,859 KWD per month. Your average tax rate is 1.3% and your marginal tax rate is 0.0%. 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 0 KWD, hence, your net pay will only increase by 100 KWD.
