Why does the Thai embassy request tax returns for the DTV visa application?

The inquiry revolves around the requirement for tax returns from the last two years for a Digital Nomad Visa (DTV) application in Thailand. While the primary requirement is to show a minimum balance of 500,000 THB in the bank, the embassy may ask for additional documentation, including tax returns. This can serve to verify the applicant's income and legitimacy of funds, even if income requirements are not explicitly stated. The conversation reveals differing opinions on the significance of the tax returns and the discretion of embassies in requesting documentation that goes beyond basic stated requirements.
