Thank you so much, and thank you for the amount of work you've put into making this document. Wow, I was really misinformed.
Just to make sure I understand this:
Any money that is brought into Thailand during 2024 that was earned before January 1, 2024, will be "managed by the previous interpretation of the rules", which means that it will not be taxed, since it was earned in a different year. Only income earned beginning January 1, 2024, can possibly be considered assessable income for money brought into Thailand from January 1 forward.
So, if I bring money into Thailand in 2024, I must determine whether any part of it is assessable income or not. In the case of money that is part principal and part gains or interest, only the portion of the money that is INCOME (either capital gains or interest) would be assessable, not the principal. And so, in net effect, any money that I had on January 1, 2024, if brought it into Thailand, would not be assessable income. Of course, if I earned any interest or capital gains on that money during 2024, and it was part of the money brought in, that portion of the money brought in would be assessable.
Did I get that correct?
