Yes, if you are not a tax resident in Thailand (i.e., you spend fewer than 180 days per calendar year in the country), you will not be required to pay taxes there. However, many countries now require individuals to provide proof of tax residency elsewhere in order to avoid being taxed in their country of origin. So plenty of us can't travel worldwide without paying tax at all.
Well in most countries you must pay taxes, so that isn’t much of a point. Rules are clear. There are tax treaties between countries to prevent double taxation. If the goal is to evade taxes worldwide, then Thailand is probably not a suitable (or less and less suitable) place to reside (Thailand is moving forward:CRS and others).
That's your excuse, not the reality. You become a tax resident when you spend 180 days or more in Thailand within a calendar year, regardless of whether you have a Thai bank account. Money brought into Thailand is not only considered when transferred by bank; it also includes credit card spending and cash. If the authorities decide to enforce this more strictly, they will. Thailand has already signed the CRS, which is a significant change compared to previous years. And do not forget: they can go back up to 10 years to check whether you reported income when you were required to. Not everyone, even tax residents, will need to pay taxes (Treaties and so ones) but hiding behind the "I don't have a Thai bank account and I'm evading taxes worldwide" excuse will not work for long.
