You keep pushing the work permit line. Work permit has nothing to do with taxation. I never said that. I was amused that you went totally unprepared to the tax office to make enquiries and when they showed you the door, you went into meltdown
Saying anything in Thailand is taxable is INCREDIBLY STUPID, but so many idiots think one size fits all. Everybody's situation is different and every DTA is different.
Credit Card usage in Thailand is most certainly a remittance. But you are free to kid yourself otherwise. Show me the law that says credit card purchases are not considered remittances!
