I'm 4 days late for my 90 day report. The fine will be 2,000, correct?
TLDR : Answer Summary
If you file your 90-day report within 7 days of the due date, there is no fine. However, if you are 8 days or more late, a flat fine of 2,000 baht applies, regardless of how many additional days late you are. There is a minimum fine of 2,000 baht at the immigration office, and the higher fines (up to 5,000 baht) mentioned apply only if you are arrested for another reason and it is discovered that you are not complying with the reporting requirement.
