Just the headache of WW taxation will make me leave Thailand.Really depends if you live hand to mouth (income) or have savings/investments that you can pull from to live off.
I.e some of us have principle invested that allows years/decades of grandfathered in prior income so current stance remains unaffected and the way to deal with WW income is to use a vehicle as Thailand is still very much territorial on that front
Even investments that aren't taxable in Thailand will need to be declared and have a whole host of paperwork. No thanks.
