TM30 Explained: What Landlords Need to Know About Foreign Tenant Registration

If you're renting out a condo in Bangkok to a foreign tenant, you've probably heard about TM30. Maybe someone mentioned it casually, or your tenant asked about it, and you weren't quite sure what they meant. Here's the thing: TM30 isn't optional, and getting it wrong can actually cost you money and create headaches with immigration. Let me break down what this form actually is and why it matters for landlords in Bangkok.

TM30 คือแบบฟอร์มแจ้งข้อมูลที่พักชาวต่างชาติ

TM30 is an official notification form that property owners must file with Thai immigration when a foreign national moves into a residential property. Think of it as registering your tenant with the government. The form's full name is "Notification of residence of an alien," and it's required by law within 24 hours of your tenant moving in.

When you rent a one-bedroom condo on Sukhumvit near Nana BTS for 25,000 baht a month to an expat working at a tech company, you need to file this form. No exceptions. It doesn't matter if it's a short-term or long-term rental. Immigration wants to know who's living where.

The form is short, straightforward, and free to file. But skip it, and you could face a fine up to 400 baht per day that your tenant is living there unregistered. Over a year, that adds up quickly.

ใครต้องทำแบบฟอร์ม TM30

As the property owner or landlord, you're responsible for submitting TM30. Not your tenant, not the condo management office. You. That's the law. Some condo management companies offer to handle it, which is convenient, but the legal responsibility stays with you.

If you own a studio apartment in Phetchaburi Soi 39, 12,000 baht a month, and you rent it to a British expat, you need to file TM30 within 24 hours of their arrival. If you own multiple units and rent them out regularly, you'll be filing this form often.

The only exception is if your tenant is a Thai national. Foreigners only. But most renters in Bangkok's condo market are expats anyway, so this applies to you.

ที่ไหนและวิธีการยื่น TM30

You submit TM30 at the immigration office that covers the area where your property is located. In Bangkok, that usually means heading to your local immigration office. If your condo is in Watthana District near Thonglor BTS, you'd go to the Thonglor Immigration Office. If it's in Khlong Toei near Lumphini Park, you'd use the Lumphini office.

You have two options: file it yourself in person, or send your tenant to file it on your behalf using a TM.30 form with your signature and thumbprint. Many landlords give the form to their tenant and ask them to submit it, which actually works fine. Just make sure they do it within 24 hours.

You can also file online through the Thai immigration website, though the process requires a PIN number that you get from your local immigration office. Some landlords skip the online route because it's easier to just hand the form to their tenant and let them submit it.

TM30 กับสัญญาเช่าและการบันทึก

TM30 is separate from your rental agreement. You still need your own landlord-tenant contract that covers the terms, rent amount, utilities, and house rules. The rental contract is between you and your tenant. TM30 is just the government notification.

Keep copies of everything. When you rent a two-bedroom unit in Rama 4 near Chit Lom BTS for 35,000 baht, get a signed TM30 receipt from immigration or from whoever files it. Keep that receipt with your rental records. If immigration ever questions the residency status of your tenant, you have proof you did your job.

Some property owners staple the TM30 receipt to their copy of the rental contract. It's good practice. It shows you took the process seriously.

ปัญหาที่เกิดขึ้นเมื่อลืม TM30

Not filing TM30 creates real problems. The fine starts at 400 baht per day per tenant. If you have one tenant and don't file for three months, you're looking at 36,000 baht in fines. That's painful money.

More importantly, your tenant's immigration status becomes technically irregular. If they need to extend their visa, open a bank account, or register with their home country's embassy, missing TM30 documentation can cause complications. They might need to prove their residency for visa purposes, and without TM30, they're stuck.

Immigration can also show up at your property and check. It happens more often in areas with high concentrations of expats, like around Phrom Phong BTS or Ari BTS. If they find someone living there without a registered TM30, questions get uncomfortable fast.

Honestly, filing TM30 takes maybe 15 minutes if you do it yourself, or zero minutes if your tenant does it. The cost is nothing. The potential headache and fine are real. It's not worth skipping.

Here's the bottom line: when you rent out your Bangkok condo to a foreigner, file TM30 within 24 hours. It's the law, it protects both you and your tenant, and it takes almost no effort. Whether you're renting a 15,000 baht studio or a 100,000 baht three-bedroom, the process is the same. Keep your receipt, keep your records, and move on. Your relationship with immigration stays clean, and your tenant can handle their visa requirements without stress.
