เจ้าของบ้านแจ้ง TM30 ออนไลน์: ขั้นตอนละเอียดที่ทำตามได้

You just rented out your condo near BTS Phrom Phong to a nice couple from Japan. The lease is signed, the deposit is paid, and they are moving in next Saturday. But there is one thing that can turn your smooth rental into a legal headache faster than a motorcycle cutting through Sukhumvit traffic: the TM30 form. If you are a property owner or landlord in Thailand renting to a foreign tenant, you are legally required to report their stay within 24 hours of arrival. Miss it, and you could face fines up to 10,000 THB per offense. The good news? You can now file the TM30 online from your living room. Here is exactly how to do it, step by step, with zero guesswork.

What Is the TM30 and Why Should Landlords Care?

The TM30 is officially called the "Notification Form for House Masters, Owners or the Possessors of the Residence Where Foreigners Stay." It is a requirement under Section 38 of the Immigration Act B.E. 2522. Every time a foreign national checks into your property, whether it is a condo in Thonglor, a house in Bangna, or a serviced apartment off Ratchadaphisek, you must notify the Immigration Bureau within 24 hours.

This is not optional. It applies to every foreign tenant, not just tourists. Even if your tenant has a work permit or a long-term visa, you still need to file. And it is not just for the first move-in. If your tenant travels abroad and re-enters Thailand, a new TM30 notification must be filed again.

Think about it this way. Suppose you own a one-bedroom unit at Life Asoke Hype near MRT Phetchaburi and rent it to an Australian software engineer for 22,000 THB per month. He flies to Bali for a long weekend. When he comes back, you owe Immigration another TM30 filing. According to the Immigration Bureau, landlords who fail to report can be fined 800 to 2,000 THB per day of delay, up to a maximum of 10,000 THB. In practice, enforcement has been inconsistent, but the trend is toward stricter compliance, especially in central Bangkok districts.

Setting Up Your Online TM30 Account

Before you can file anything, you need to register on the Immigration Bureau's online system. Head to the official TM30 online portal at immigration.go.th and look for the section labeled "Notification of residence for foreigners" or the TM30 online service link. The interface can feel a bit clunky, but it works.

You will need the following documents ready in digital format: a copy of your Thai ID card or passport if you are a foreign landlord, a copy of the property title deed or the condo ownership certificate, and a copy of the lease agreement. Scan or photograph these clearly. File sizes should generally be under 2 MB each in JPG or PDF format.

Here is a real scenario. Say you own two units at Ideo Mobi Sukhumvit near BTS On Nut. You rent one to a French couple and the other to a Korean single professional. You only need one landlord account, but you will submit separate TM30 notifications for each tenant. During registration, you will set a username and password. Save these somewhere secure because you will use this account repeatedly.

The approval process for your account typically takes one to three business days. Immigration staff manually verify the documents you uploaded. Once approved, you receive a confirmation and can start filing.

Filing the TM30 Online, Step by Step

Once your account is active, here is the actual filing process broken down into clear steps.

Step one: Log in to the TM30 system. Step two: Select "New Notification" or the equivalent button on the dashboard. Step three: Enter the foreign tenant's details, including full name as shown on passport, nationality, passport number, visa type, and date of arrival at your property. Step four: Enter the property address in full, matching the address on your title deed. Step five: Upload a copy of the tenant's passport photo page and their most recent entry stamp or visa page. Step six: Review everything and submit.

You should receive a confirmation number immediately. Save this. Your tenant may need it when they do their own 90-day reporting at Immigration or when they apply for visa extensions at the Chaeng Watthana Government Complex.

For example, if you rent a two-bedroom condo at The Base Park West near BTS Udom Suk to a British teacher earning a living in Bangkok at around 18,000 to 25,000 THB per month in rent, you file the TM30 once when they move in. If they take a visa run to Vientiane and return, you file again. The online system makes repeat filings faster because your property details are already saved.

Common Mistakes That Cause Rejections or Delays

The system is functional but not forgiving. Here are the most common errors that trip up landlords.

Mismatched addresses are the number one problem. If your condo is registered as unit 1234, Building A, but you type "Room 1234, Tower A," the system might flag it. Always use the exact wording from your chanote or condo ownership document.

Blurry document uploads cause rejections too. Take clear photos in good lighting or use a scanner app on your phone. Make sure the passport number and entry stamps are fully legible.

Another frequent mistake is filing late. The 24-hour window starts from the moment the foreigner arrives at the property, not from when the lease begins. If your tenant at Aspire Rama 9 near MRT Phra Ram 9 signs a lease on Monday but moves in on Thursday, the clock starts Thursday.

Some landlords also forget that the requirement applies to every re-entry into Thailand. A data point worth noting: immigration statistics indicate that over 3.5 million TM30 filings were processed in 2023, reflecting just how widespread and routine this requirement has become for property owners across the country.

Online Filing vs. In-Person Filing vs. Using an Agent

You have three main options for submitting TM30 notifications. Each has trade-offs depending on how many units you manage and how comfortable you are with the online system.

Method	Cost	Time Required	Best For	Key Consideration
Online (immigration.go.th)	Free	10 to 15 minutes per filing	Landlords with 1 to 5 units	Requires initial account setup and document uploads
In-Person at Immigration Office	Free	1 to 3 hours including travel and waiting	First-time filers who want guidance	Chaeng Watthana or local immigration offices can be crowded
Hiring a Visa Agent	500 to 2,000 THB per filing	Agent handles everything	Landlords with many units or no time	Make sure the agent is reputable and provides confirmation receipts
Property Management Company	Usually included in management fee (8 to 15% of rent)	Handled automatically	Absentee or overseas landlords	Check that TM30 filing is explicitly in the service contract

For most individual landlords renting out a condo near BTS Thong Lo or MRT Sukhumvit, the online method is the clear winner. It is free, relatively quick once you are set up, and you get a digital record of every filing.

What Happens If You Ignore the TM30 Requirement

Let us be direct. Many landlords in Bangkok have ignored TM30 filings for years without consequence. But the enforcement landscape is shifting. Immigration has been digitizing records and cross-referencing lease agreements with TM30 filings more actively, particularly in high-density rental areas like Asoke, Silom, and Ari.

The penalties themselves are not enormous, but they add up. A 2,000 THB fine might not sting once, but if you have multiple tenants and multiple re-entries, it compounds. More importantly, your tenant can face problems. Without a valid TM30 on file, foreigners may encounter difficulties when extending their visa, completing 90-day reports, or even opening a bank account. The Bank of Thailand oversees financial institutions that increasingly require proof of registered address for foreign account holders.

Imagine you own a studio at Lumpini Suite Phetchaburi near MRT Makkasan, renting it for 15,000 THB per month to a digital nomad from Germany. They go to extend their visa at Chaeng Watthana and get turned away because no TM30 is on file. They call you frustrated. You scramble to file, but now you are also looking at a potential fine. This is entirely avoidable with 15 minutes of online work.

Making TM30 Part of Your Landlord Routine

The smartest landlords in Bangkok treat TM30 filing like they treat collecting rent: it is just part of the process. Build it into your move-in checklist. On the day your tenant picks up the keys, collect a clear photo of their passport and latest entry stamp. File the TM30 that evening. Set a reminder in your phone to ask tenants to notify you whenever they travel internationally and return.

Some landlords include a clause in the lease agreement asking tenants to inform them of any international travel, specifically so the TM30 can be re-filed promptly upon return. This is a small addition that prevents big headaches.
