Did you know your employer also pays tax on your salary? It costs the employer 375 บาท to pay you 40,755 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 1.30 บาท goes to the government.
Real tax rate
12.9%
So, with you and the employer both paying tax, what used to be a 12.1% tax rate now rises to 12.9%, meaning your real tax rate is actually 0.8% higher than what it seemed at first.
Summary
If you make 978,120 บาท a year living in Thailand, you will be taxed 118,616 บาท. That means that your net pay will be 859,504 บาท per year, or 71,625 บาท per month. Your average tax rate is 12.1% and your marginal tax rate is 21.8%. 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 21.83 บาท, hence, your net pay will only increase by 78.17 บาท.
Bonus Example
A 1,000 บาท bonus will generate an extra 782 บาท of net incomes. A 5,000 บาท bonus will generate an extra 3,909 บาท of net incomes.
