Did you know your employer also pays tax on your salary? It costs the employer 34.62 บาท to pay you 3,150 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 1.16 บาท goes to the government.
Real tax rate
11.5%
So, with you and the employer both paying tax, what used to be a 10.5% tax rate now rises to 11.5%, meaning your real tax rate is actually 1% higher than what it seemed at first.
Summary
If you make 819,000 บาท a year living in Thailand, you will be taxed 86,000 บาท. That means that your net pay will be 733,000 บาท per year, or 61,083 บาท per month. Your average tax rate is 10.5% and your marginal tax rate is 20.0%. 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 20 บาท, hence, your net pay will only increase by 80 บาท.
Bonus Example
A 1,000 บาท bonus will generate an extra 800 บาท of net incomes. A 5,000 บาท bonus will generate an extra 4,000 บาท of net incomes.
