There are dozens cresting content in Thailand on tourist visas, visa exempt and retirement visas. I have never ever seen any reports of anyone getting into trouble for it. The nearest is when people have done actual client facing work like acting as tour guides or drivers. They are the ones who get into trouble.
Anonymous participant 463 There are people doing it on a DTV but it is a very grey area. Some are not just publishing content but offering services in Thailand like booking trips and accom - that is definitely a No-no
Very good question. Do not take this as 100% advice but I was told by tax advisors if I had no assessable income then no need for a tax return. Thus I did not complete one this year. I also know some tax offices will not even issue a TIN if no assessable income. Just being in country 180 days is not enough.
