Did you know your employer also pays tax on your salary? It costs the employer 375 บาท to pay you 155,220 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 2.41 บาท goes to the government.
Real tax rate
24.0%
So, with you and the employer both paying tax, what used to be a 23.9% tax rate now rises to 24.0%, meaning your real tax rate is actually 0.1% higher than what it seemed at first.
Summary
If you make 3,725,280 บาท a year living in Thailand, you will be taxed 888,884 บาท. That means that your net pay will be 2,836,396 บาท per year, or 236,366 บาท per month. Your average tax rate is 23.9% and your marginal tax rate is 30.0%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 บาท in your salary will be taxed 30 บาท, hence, your net pay will only increase by 70 บาท.
Bonus Example
A 1,000 บาท bonus will generate an extra 700 บาท of net incomes. A 5,000 บาท bonus will generate an extra 3,500 บาท of net incomes.
