Did you know your employer also pays tax on your salary? It costs the employer 375 บาท to pay you 276,250 บาท. In other words, every time you spend 10 บาท of your hard-earned money, 2.80 บาท goes to the government.
Real tax rate
27.9%
So, with you and the employer both paying tax, what used to be a 27.8% tax rate now rises to 27.9%, meaning your real tax rate is actually 0.099999999999998% higher than what it seemed at first.
Summary
If you make 6,630,000 บาท a year living in Thailand, you will be taxed 1,844,103 บาท. That means that your net pay will be 4,785,897 บาท per year, or 398,825 บาท per month. Your average tax rate is 27.8% and your marginal tax rate is 34.3%. 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 34.28 บาท, hence, your net pay will only increase by 65.72 บาท.
