Who is tax resident in Thailand?
Thailand counts days in the calendar year and treats a stay totalling 180 days as the threshold for residence. Revenue Department guidance says "more than 180 days" while PwC writes "at least 180", so the wording differs at the exact limit. A resident pays tax on Thai-source income and on the part of foreign income brought into the country.
The trap to know
Money saved abroad before 2024 can be brought in without Thai tax, whereas income earned from 2024 stays taxable when remitted in any later year. Because the date of earning decides, the origin of each transfer has to be traceable. The foreign tax credit is also capped at the Thai tax on that income, and any excess cannot be carried forward.

How much is THB 5,100,000 after tax in Thailand?
THB 3,845,650 a year, or THB 320,471 a month, for a single resident employee. Income tax comes to THB 1,243,850 and contributions to THB 10,500. At THB 10,000,000, the share you keep moves to 70%.
