Not quite sure how you come up with the statement ‘not required to file tax at this point’. The law is absolutely clear about that, you spend 183 days per year in Thailand, you become a Thailand tax resident. If OP spends those days per year in Thailand and if there is income brought into Thailand, it must be declared. Especially those on remote work DTVs should get a TIN and declare, it’s super easy, the Thai tax declaration isn’t hard, there are even a few deductibles you can use, e.g. buying Thai stocks or donating to hospitals etc.
