All laws in Thailand are sketchy. It’s not just tax. The way they treat immigration where if you leave you pay a fine, but if you go to immigration if you overstay and they thrown in jail for months years or even decades without a court hearing is alarming.
Even with the DTV, it was quite clear that internally the offices knew and seemed to have agreed on what was needed but was not then shared publicly.
Thailand is a mine field for laws. One I and others don’t want to touch if possible. The tax is irritating, but the legal structure and how it is implemented, to me, is just absolutely untenable and not something I want anything to do with.
If you do, fine, but do it knowing that you may be thrown in jail or who knows what punishment they decide internally and not share with us for doing it wrong, which changes like the wind.
