I am planning to retire in Thailand. I was wondering about the following issue. Do Swiss nationals pay personal income tax as retirees in Thailand?
Only income earned inside Thailand shall be subjected to tax during retirement. Therefore, you will not be obliged to pay any taxes for any income you have earned from overseas. Also, personal income taxes are not required for retirees in Thailand. Note that you can’t work in Thailand while on a retirement visa.
You would need to apply for a work permit. Once you stopped working you would have to leave Thailand and return with a 90-day OA visa and start the process again of extending the retirement visa for 1 year.
