Like many of you, I was concerned about filing a tax return here in Thailand.
To be clear, I have no income here, and I don't receive money in Thailand from abroad.
I just spoke to our accountant here and she told me that as long as I fill out a tax return in my country (the USA), one is not required to be filled out here.
I thought that might be helpful to some of you.
Of course, get your own professional opinion.
