What should I do about my TM30 and 90-day report situation in Thailand?

If anyone find out that they have missed a deadline, with anything to do with Thai authorities, then make sure to take steps to correct it, as soon as possibel after discovering the mistake.

Practically, it doesn't matter when it was submitted at that location. Nothing to fix. Just do your 90 day report as per your situation in person or online.

You've been in Thailand for 120 days, there's no 'fixing' not having filed a 90 day report. You haven't filed one in time. If you need anything from an immigration office, and they check to see if you filed a 90 day report, they may well fine you ฿2000 because you didn't.

That's it. That's the only thing that happens. If you don't ever need anything from an immigration office before you leave the country, nothing happens.

On your next entry, count 89 days after you arrive and file a 90 day report in person. You can do that 14 days before or 7 days after that date.

Or you can just not, and pay the fine if they ask you to.

He Condo Landlord or their Agent needs to have submitted a TM30 when you moved in. The hotel one is out of date. You need a TM30 at most offices before yiu can do the 90 Day report. TM47 forms are available at immigration.
