Did you know your employer also pays tax on your salary? It costs the employer 34.62 บาท to pay you 1,179 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 0.83 บาท goes to the government.
Real tax rate
8.1%
So, with you and the employer both paying tax, what used to be a 5.4% tax rate now rises to 8.1%, meaning your real tax rate is actually 2.7% higher than what it seemed at first.
Summary
If you make 306,540 บาท a year living in Thailand, you will be taxed 16,476 บาท. That means that your net pay will be 290,064 บาท per year, or 24,172 บาท per month. Your average tax rate is 5.4% and your marginal tax rate is 8.9%. 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 8.91 บาท, hence, your net pay will only increase by 91.09 บาท.
Bonus Example
A 1,000 บาท bonus will generate an extra 911 บาท of net incomes. A 5,000 บาท bonus will generate an extra 4,555 บาท of net incomes.
