Sorry but jumping in a bit late on this topic. So, if I gift my non-working thai wife 3,000,000 baht of US work earnings to her separate US bank account yearly in the United States, create a doc that specifies that it is a gift, then wire that money from that separate account to my wife's separate Thai bank account, then she moves a bit of that money into my separate Thai bank account to add to my US Social Security (non-taxable to Thailand by virtue of tax treaty) coming to my separate account, we have no tax obligation to Thailand.
Sound about right?
Hope all well with everyone.
