Real tax rate
0.5%
So, with you and the employer both paying tax, what used to be a 0.2% tax rate now rises to 0.5%, meaning your real tax rate is actually 0.3% higher than what it seemed at first.
Summary
If you make 1,580,640 KWD a year living in Kuwait, you will be taxed 3,255 KWD. That means that your net pay will be 1,577,385 KWD per year, or 131,449 KWD per month.
