Why would anyone want to try that? Can you explain your goal for having a bank account in Thailand with money just sitting there? No bank is going to give you any rate of interest worth thinking about…
I already told you - you need a specialist to determine that. The default will be the last place you were tax resident…. The word “resident” doesn’t have a connection to your location or where you are registered. My friend is tax resident in Hong Kong but has never stepped foot in Hong Kong in his life, never had a job there, and never registered there.
Again ZERO RELATION to where you are or whether you’re registered anywhere
your living residence is totally separate from your tax residence. I have not been registered in NL for a long time but as still tax resident there.
You should probably speak with an accountant since you will need to consider where your income is generated and received, as well as other factors that contribute to tax residence
