I personally will have spent more than 180 days outside Thailand this year. Ipso facto my spending has probably dropped by a 50%. For next year I am looking at a similar strategy. I am waiting to see if the government implement laws taxing my worldwide income regardless of how much is brought into Thailand. If the situation stays as is I will reluctantly stay over the 180 days in LOS and suck up paying tax on what I import. However I would be importing the minimum and because of that be spending far less than in the past. The flat rate option may be attractive depending on the rate, if that is ever introduced, which probably is highly unlikely
