Well here in Samui that is how they calculated it. I was 15 days late so they charged me 2000 which is the maximum. I watched them do it on the calculator and my Thai is good enough to converse with them on this subject. BUT the best of it is that they refunded me 1000 baht as a gesture of good will. It is the only time I have ever filed late. I now do it on line most of the time unless I miss the 1 week before window.
you guys just waiting to take someone down. Guess you don't have anything else to occupy you in life. I edited what I wrote immediately after because I realized that it was erroneous. You have a 7 day grace period.
I read what I wrote and corrected it,lol. You move fast ! Anyway last time I was late reporting the fine was 2000 baht and I paid but when they gave me back my passport they had 1000 baht refund inside. So speaking a little thai and being polite does wonders.
The owner of the property is responsible for doing your TM30 report, not you. They have to pay the fine. I don't understand why you should pay a fine for something you are not responsible for and cannot actually do yourself.
