Landlords Guide to Filing TM30 Online in Bangkok

If you are renting a condo in Bangkok, you have probably heard about TM30. This is the official notification that landlords need to file with immigration when a foreign tenant moves in. The good news? You can now file it online without stepping foot in an immigration office. The bad news? A lot of landlords still do not know how to do it, and tenants end up scrambling at the last minute. Let me walk you through exactly how to handle this so you stay compliant with Thai law and avoid the stress.

Why TM30 Matters More Than You Think

The TM30 form is basically your landlord's legal responsibility to inform immigration that you are living at their property. If your landlord does not file it within 24 hours of your move-in date, technically they can be fined. You do not want to be the reason your landlord gets in trouble, and you definitely do not want immigration knocking on your door because paperwork was not filed.

I have seen tenants in Thonglor and Ekkamai get their rental situations complicated because landlords kept pushing off the TM30. Then when they needed to extend a visa or report to immigration themselves, everything fell apart. It only takes a few minutes to do this online now, so there is no excuse for delays.

Getting Your Landlord on Board First

Here is the thing about TM30 filing. Your landlord is the one who legally has to submit it, not you. So your first job is making sure they understand this and that you give them all the information they need. Do this on day one when you sign your lease.

Ask your landlord if they have filed TM30 online before. If they have not, offer to walk them through it or send them a link to the immigration website. You need from them: their Thai ID number, your passport number, your date of arrival, and your rental address with the exact unit number. If you are renting a condo in Ari or Petchburi, write down your building name, soi, and all identifying details.

Some landlords prefer hiring a property agent or a service to do this for them, and that is fine too. Just confirm it gets done within 24 hours.

The Step by Step Online Filing Process

The TM30 form is filed on the Thai immigration website at www.immigration.go.th. Your landlord will need to go to the online TM30 system, which is clearly labeled on the homepage. Here is how it actually works in practice.

Your landlord logs in with their Thai ID number. They select "TM30 Notification" from the menu. Then they fill in the form with your details: your full name, passport number, date of birth, nationality, and occupation if you want to include it. Next comes the address section. This is where people mess up. They need to input the exact building name, soi number, house number, and sub district. For example, if you live in a condo on Soi 26 Thonglor, they write out the complete address exactly as it appears on your rental agreement.

Then they select the date you moved in. This date should be within the last 24 hours when the form is actually submitted. They upload a photo of your passport data page. Then they upload a photo of your landlord's Thai ID. Finally, they click submit and print or save the confirmation number.

Common Mistakes That Actually Cause Problems

I have helped enough friends through this process to know where things typically go wrong. The biggest mistake is entering the wrong date. Your landlord cannot file TM30 for a move in date from three months ago. It has to be current. If you moved in on March 15th and your landlord is filing on March 18th, the system will not accept it.

Another frequent issue is the address format. If your condo address includes floor and unit number, make sure all of that is included. At a place like Noble Ploenchit near Ploenchit BTS, you need to write "Building A, Floor 12, Unit 1205" or however your lease lists it. Abbreviations and sloppy formatting can cause rejections.

Also, passport photos need to be clear enough to read. Do not submit blurry photos. Your landlord should take a photo of both sides of the passport data page with good lighting. Same goes for their ID.

After You Get the Confirmation Number

Once your landlord submits the form online, they will get a confirmation number. This is your proof that TM30 was filed. Ask them to send you a screenshot or the confirmation page. Keep this safe because you might need to show it to your landlord later for any reason, or if you rent through an agent, the agent will want proof of filing.

The filing is now complete. Your landlord does not need to go to an immigration office. The whole thing happens digitally, which honestly makes life so much easier compared to how it used to work. That confirmation sits in the immigration system, and you are covered.

TM30 filing online has made this process genuinely simple. You just need a landlord who is willing to spend ten minutes filling out a form and taking two photos. Make sure you have a conversation about this on move in day. Give them the website address. Walk them through it if needed. In Bangkok's rental market, especially in areas like Bangkapi and Rama 9 where a lot of foreigners live, most landlords now understand this process.

If your landlord is dragging their feet or seems confused, consider using a Thai visa service or asking your building management if they handle TM30 filings for residents. Many condos do this as a service. The key is making sure it gets done within 24 hours of your arrival, so you stay on the right side of immigration law and can focus on actually settling into your new place in Bangkok.

When you are searching for your next rental on Superagent.co, make sure your landlord understands their TM30 responsibilities before you sign anything. A good landlord will already know about this or be willing to handle it immediately. That is one of the signs you have found a reliable rental situation.
