Do I need to submit a TM30 form for my accommodation on a Tourist Visa in Thailand?

@Frank *******

you cannot do it yourself without either the landlords TM.30 account information (if they have an account) or setting up an account which will still needs a letter from the landlord a copy of their house book and ID which both need to be signed by them.

You're better off talking to the landlord and seeing if they will submit the TM.30. explain it can be done online without the need to visit immigration and only takes a few minutes to set up the account.

@Frank *******

It can be done online. If the form is submitted by you, rather than by house owner, you need info from them though, like owner account info etc. On some ABnb listings now, the “host” says upfront they will give “guest” the necessary info but it’s up to “guest” to file the TM30. Ask your GF’s landlord if he is going to file it. It’s my understanding as well that if the house owner doesn’t file it within 3 days, whoever does eventually file it will pay a fine. You or the landlord; whoever files it, will pay the fine. I don’t recall how much the fine is. Good luck; I hope your landlord is on top of things and cooperative. You will either need a hard copy of the form to give to immigration or proof that the form was done online. My visa agent handled all that since I had no TM30.

@Frank *******

if you're staying at the same place there wouldn't be a new TM30. A TM30 is supposed to be filed within 24 hours of any foreigner arriving at a location.
