Real tax rate
10.2%
So, with you and the employer both paying tax, what used to be a 9% tax rate now rises to 10.2%, meaning your real tax rate is actually 1.2% higher than what it seemed at first.
Summary
If you make 665,004 บาท a year living in Thailand, you will be taxed 59,901 บาท. That means that your net pay will be 605,103 บาท per year, or 50,425 บาท per month. Your average tax rate is 9.0% and your marginal tax rate is 15.0%. 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 15 บาท, hence, your net pay will only increase by 85 บาท.
