"Tax Resident: Anyone who stays in Thailand for more than 180 days cumulative (not consecutive), regardless of nationality or residence status in Thailand"
"This depends on the duration of your stay. According to Thai tax law, anyone who stays in Thailand for over 180 days out of a calendar year will be considered a tax resident by the Thai government. You will be liable to pay Thai income taxes on your foreign income if you are a tax resident."
Sorry; you misunderstand. It's a retorical question. Because you aren't a Thai citizen, or have a proper, non tourist visa, you can not have a bank account in Thailand. Same like in most parts of the civilized world.
