ok but no bank account as deemed by the Thai government means no income is tagged to the person. The Thai government is closing accounts currently closing these accounts. This is why I recommended the OP to seek advice. Here's just one video.
your incorrect too. You pay taxes sure where you are a tax resident and where your income is banked is part of this. A person with a DTV cannot hold a bank account here and stays 180 day only. A DTV Holder is classified a tourist this not a tax Resident here.
