Where would you be a tax resident of if you spent less than 180 days a year in Thailand?
I'm non-resident British, so technically no tax in the UK unless i do business, have real estate etc in the UK, which i avoid, and also don't have sterling accounts or visit the UK.
Therefore it comes down to the 180/183 day tax rule.
Under Thai law they are loosing the 12 monthly tax harvesting system, and moving to the 180 day (or 183 day) tax rule system, so spend less than 180 days there, and spend the rest elsewhere and the game continues.
Note thats on dividends etc not sure on Income, i don't get that, as i get a dividends every so many years (5+) and live off that for the proceeding years.
But the new process means 'money remitted' will be taxed, as a elite visa holder, i'd drop the elite and go to visa exempt, and spend less than 180 days in the country, thus not taxed for funds brought in.
Company likely being moved to Malaysia (Labuan) which is tax free for the company, myself would have to pay tax if i take up the visa offering and live in Malaysia (over or under a certain period of time unsure).
Otherwise perpetual traveller (again not ideal with children) but most countries don't charge tax for dividends if its overseas (it would be) and under 180 days residence (which it would be) worst case, Caymans, Dubai etc and liquidate everything and live there.
I'm not enthusiastic about Dubai as its soul destroying, but Thailand will have a higher tax than a lot of Western countries going forward reading this.
