It seems that you didn’t fully understand my question, and if you don’t have the answer, that’s okay. I am very familiar with Thailand’s tax payment rules. I have worked there and had a work permit for several years. Since then, I have left and become a tourist again.
My question is: If I return with a DTV visa, stay in Thailand for more than 180 days, and want to officially become a Thai tax resident, can I go in March 2025 to declare my income while holding a DTV visa in order to validate my tax residency in Thailand?
