What is an Income Tax Payment Certificate? When foreigners work in Thailand, they have to pay taxes here. Your Thai employer must get a work permit for you to be able to pay you legally. Every month when they pay you salary, they need to withhold your personal income tax and submit it to the Thai Revenue Department by the 7th of the following month (or 15th if they do it online). At the end of the year (or at the time you leave the company during the year), the employer must give you a document called 50 Tawi, or withholding tax certificate. The document has the detail of the total income you earned that year from this company, the total tax and the total social security amounts they withheld from you that year. However, it is not your Income Tax Payment Certificate.
When you prepare your personal income tax return at the beginning of the following year (31 March is the deadline), you will have to fill out the amount of tax withheld that is written in the withholding tax certificate. This tax is your tax credit. It is the tax you paid during the year by the employer’s withholding it from your income. If you did not have other sources of income from anywhere else, most likely you will not have to pay more taxes if your employer’s payroll team calculated your monthly withholding tax correctly. In some cases you will get a tax refund.
When you file your personal income tax return (PND90 or PND91 depending on whether you have income sources other than from work), you will get a receipt issued by the Revenue Department. This receipt is not enough of a proof to the Inland Revenue Service in your home country. You will need to request the Thai Revenue Department to issue an “Income Tax Payment Certificate”, which is in English and it is accepted as the proof that you paid taxes in Thailand.
An “Income Tax Payment Certificate” is not the same as a “Tax Resident Certificate”. The latter is the certificate issued by the Thai Revenue Department to certify that you were a tax resident in Thailand in the year it is issued for. Only when you have stayed in Thailand for 180 days or more in a calendar year can you request for a Tax Resident Certificate.
