Mark Levy all UK citizens are UK residents, but not all UK residents are citizens. As a citizen when you leave the UK you can relinquish your 'tax residency' but not your 'residency'.
Mark Levy it is confusing as legalese and common parlance can be quite different. 'Residence' pertains to your rights not your location. You can be resident in multiple countries simultaneously but may or may not physically be located in any of them. 'Tax Residency' is a separate concept and pertains to your liabilities. You could be liable for taxes independent of your 'residency' and or your location. I'm a resident of both my home country and my wife's home country but live in neither.
A lot of people are offering incorrect information here so be cautious about soliciting tax advise on Facebook. Do your own research.
The situation as I understand it is, Thailand will tax your remittances into your Thai bank accont if you are a 'tax resident' at the time of the transaction. There are perfectly legal work-arounds, but you still need to know what you're doing.
I just saw a blind Thai woman on the BTS last week. She seemed to be getting about on her own OK, the security guards helped her into the train and I helped her locate the grab pole to steddy herself. Security guards in Bangkok are everywhere and they are very helpful, unfortunately few speak English.
Sorry I could not answer your question but I wish you the best experience in Thailand.
