Maybe it is just a ploy, that will not pass as a law. Scaremongering, to make you thankful for just having to pay the new remittance tax on income brought into Thailand, regardless of when it was earned. Either way, one should consider an exit plan or stay only 179 days. Government funds are depleted, economy is not performing, tourism mainly attracts war refugees, quality of services are abysmal(atleast in the Southern region), inflation is at an all time high, etc....Yet, all we hear is tax this, tax that, tax now. Laws are amended without warning, there is another amendment to tax on worlwide income. Could be a tactic to make everyone grateful for just a remittance tax or it could be real.
The fact is Thailand has lost its shine a long time ago. They should incentivise foreign investment not penalise it. Instead of following the Western model, which has become a total failure.
