Do I need a new work permit if I change employer in Thailand?
Short answer
Yes. A Thai work permit is tied to a named employer, workplace and position. Changing employer means the old permit is cancelled and a new application is filed by the new employer — you cannot simply carry the existing booklet or digital permit across.
The sequence matters more than the paperwork. Your permission to stay is usually tied to employment as well, so a resignation can start a countdown on the visa before the new permit is issued. Coordinate the resignation date, the cancellation filing by the outgoing employer, the new employer's application to the Department of Employment, and the extension of stay at Immigration as one plan — ideally with the new employer's documents ready before the last working day.
Ask the outgoing employer in writing for the cancellation confirmation and the withholding tax certificate; both get requested later and are hard to obtain once HR has moved on. Where the new role sits under BOI promotion, the filing runs through the One Stop Service Center instead, which changes the documents but not the principle.
