Did you know your employer also pays tax on your salary? It costs the employer 9,000 บาท to pay you 401,440 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 0.87 บาท goes to the government.
Real tax rate
8.5%
So, with you and the employer both paying tax, what used to be a 6.4% tax rate now rises to 8.5%, meaning your real tax rate is actually 2.1% higher than what it seemed at first.
Summary
If you make 401,440 บาท a year living in Thailand, you will be taxed 25,744 บาท. That means that your net pay will be 375,696 บาท per year, or 31,308 บาท per month. Your average tax rate is 6.4% and your marginal tax rate is 10.0%. 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 10 บาท, hence, your net pay will only increase by 90 บาท.
