Is income earned through remote work while in Thailand considered Thai-sourced or foreign-sourced income?

The classification of income earned through remote work in Thailand under the Digital Nomad Visa (DTV) is unclear and often debated. Generally, if a DTV holder works for foreign clients while in Thailand, the income is typically considered foreign-sourced and only taxable if remitted to Thailand—provided the individual meets the criteria for tax residency (staying over 180 days). Some comments suggest that working from within Thailand, even for foreign clients, could be seen as generating Thai-sourced income, which typically requires a work permit. The lack of clear official guidelines creates a grey area, prompting users to seek clarification on definitions like 'remitted' and the implications of income sourced from work done in Thailand.
