the fine for not doing the TM30 is 1600฿. I didn’t do it right away once and she only made me pay 800฿. I was about 10 days late filing it. Unfortunately, my landlord won’t do it for me so each time I have to go to immigration myself to file it.
This is for the Bangkok immigration office.
Also, since it was a Friday, along with a weekend and a holiday, I would pretty much say if you’re there on Tuesday to file it they won’t fine you.
