I had feedback from lawyer who tell me that I'd you don't remit to thailand assessable income, you don't have to fill a 0 tax report ... and when i go to thai revenue department they did not want to give me tin number without taxable income ...
Participant anonyme 384 get a tin number and fill a tax report. You can have help from agent/lawyer, about 7k to get tin number, about 10k to fill the report ( if not complicated one )
