A Thai tax resident is a person living in Thailand for more than 180 days per year. A Thai resident has, therefore, the obligation to declare the totality of its income on the Thai territory without consideration of his permanent status under the immigration requirements.
On the other hand, a person who has lived less than 180 days per year in the Kingdom of Thailand is considered a non-resident by tax authorities. However, a non-resident has an obligation to declare incomes derived from a source in Thailand.
