@Greg *****
as a general rule if you miss a report, leave/return the next time your 90 day report is due they do NOT notice you missed applying on time for the previous ones
BUT
every once in a while they do and fine you the 2000baht for the late filing on the previous report before they'll let you file a new one
I sure wouldn't bounce out and back just to get OUT of a 2000baht failure to file a 90 day report on time fine unless you have to travel somewhere 🙂
