Will take years for theThais to work out what is taxable or not. The wife went to the TO to make her return, so she queried if I had do make a return, (I have and LTR visa and haven't remitted funds earned in 2024), when she said my earning were from a UN pension, he just said: "oh not taxable". He didn't even want to read RD 743, or look at my statements, too complicated I guess.
But I am glad I have the LTR, as I could imagine a situation where, wrongly believing UN pensions aren't taxable in Thailand, I wouldn't make returns for years, and then caught in an audit by someone with different views...
