What little I read about this leaves me wondering why there is no mention of Thai accountants vying for this chunk of business. I have asked my friendly banker here in Chiang Mai if he knows of any Thai accountants that would file taxes for me and he looked at me kind of funny. Every other Thai I ask that I think might know doesn't know either.
I'm guessing that the tax system for Thais is very simple compared to Western countries, so there is little need for individual tax filing assistance. But, I would think there would be a few Thai accountants that would like this business.
