Do I need a TM30 form to extend my 60-day tourist visa exemption in Thailand?

They are legally obliged to. My landlord refused and dragged their feet, immigration told me to let them know they would be fined otherwise and that finally resolved the matter.

i was told by imigration its up to the owner to do if thay dont, thay get into trouble. as long as you can show receipt that you stayed there for those days its ok, that was at sakon nakon. maybe differant at other places.

receipt all you need.

They have to give you a tm30 that's bullshit

If you've already been in Thailand for 50 days.. and you have never filed a TM30.. then you can expect to be fined.. it is the responsibility of the hotel (or guesthouse) to do it and technically they are in breach.. but it is you that will have to pay the fine to regularise it.. it's an easy online process that costs nothing to do.. and you need the print out or screenshot to prove its been done.. you can do it yourself but would need your a copy of your Thai landord's NIC (front and back) and blue book (main page) to upload to the system.. which they may be reluctant to give you.. I'd ask them if they would assist you to do it yourself.. by sitting with you while you do it so they can watch you upload and then delete the documents.. which may make them more comfortable.. suggest you involve an English speaking Thai friend to communicate with them if their English is poor.. to explain the severity of the situation and to encourage them.. otherwise you need to find another place to stay with a more helpful landlord 😐

Most offices require you to have a TM30 filed to get an extension BUT you could just take the receipt of you staying at that guest house to the immigration office in Ayutthaya and ask them if you can do it using that address with just a receipt.

Certainly before I went to another city to try it I'd go ask the office where you are now. Worst they can say is you can't get an extension until you get a TM30, and who knows they may do it without you having one.
