What should I do if I forgot to submit my TM30 within 24 hours before my 90-day reporting in Thailand?

My landlord was late by a week until I asked about a copy for my records. Immigration in Bangkok found the discrepancy & let it slide that time but informed me of the law. Now my realtor does it on time for me. I suggest doing it now & explain the mistake to IO or stay in a hotel, then have your landlord submit the TM30 & then go to IO.

I've had several landlords refuse to do it lol it's not a big deal. You can get a tm30 done on the day with a copy of the lease and then do your 90 day straight afterwards.

If you leave when you 180 days is up dont bother nothing happens even with the 90 day reports. Its only if you need to go into an immigration office

Just forget it , nobody cares

The place you stay files the report. Technically the law states they must file within 24 hours of your arrival. However if you have no need for interaction with immigration then no one is really going to care.

For your 90 day report they will want to see a TM30 filed but they almost certainly won’t care if it was filed that day as long as it’s valid.

If you are the house owner file online before you go. If not get the house owner to file for you. If there’s complications with that then as others have said check in to a cheap hotel for a few hundred baht and get them to file. You don’t actually even need to stay. Just get their filing of a a TM30.

You only need the tm30 the day you go .

Think of it this way, if you are a tourist and you stay in a hotel they will submit a tm30 for you.

If your landlord doesn't provide it, it happens, check into a cheap hotel get a copy of the Tm30 and use that for your 90day checkin.

Your landlord/owner should be doing this as soon as you arrive.

You don't submit it. Your landlord does.
