the DTA literally determine where you are a tax resident and therefore if you can get a certificate depending on your activities and center of vital interest and all this BS. a DTA is there to avoid double︀ taxation and take precedence over the general law on taxation if I am not mistaken.︁
completely right, although Thailand don't do CRS for now, its schedule for︆ 2022 if I am not mistaken. We will see how thing goes then but we︇ could very well have to provide some proof of funds ...
now the Thai government︈ is well known to be extremely lazy and pretty much useless so ... I wouldn't︉ worry too much. This will be more of an issue for Thai citizen than foreign︊ Thai resident imho, we shall see ...
in any case, I wouldn't stay a whole︋ year in Thailand though but maybe that's just me ...
