TM30 in Thailand — What Happens Without One, and How to Fix It

The TM30 (formally: "Notification of Residence of Alien") is a notification filed with the Immigration Bureau by the "housemaster" — the owner, manager, or person in charge of a residence — whenever a foreign national stays there. The obligation is on the housemaster (typically your landlord or hotel), not on you as the foreign resident. However, you can file it yourself if the housemaster is uncooperative.

The form notifies Immigration of: the foreign national's name and passport details, the address where they are staying, and the dates.

The most significant practical consequence of a missing or outdated TM30 is at the Immigration office when you attempt to apply for a visa extension or annual extension. Immigration officers check TM30 status before processing extensions. If your TM30 is not current for your current address, your extension application will be rejected.

This is not a theoretical risk — it is a common reason for extension delays and failed applications. The officer tells you to go get your TM30 filed, then come back. This adds days or weeks to your extension process if you discover it at the wrong time.

The online 90-day reporting system (immigration.go.th) requires a current TM30 on file to process your online report. If your TM30 is not current, the online system will reject your 90-day report — forcing you to attend the Immigration office in person.

The housemaster (landlord or property manager) is liable for a fine of up to 800 THB for failing to file the TM30 within 24 hours of your arrival. In practice, this fine is rarely enforced for individual landlords — it is more relevant for hotels and guesthouses.

Foreign nationals themselves are not directly fined for a missing TM30 (it is the housemaster's obligation). However, the blocked extension is the practical consequence.

The landlord attends the local Immigration Bureau with: their Thai ID card, the property deed or lease agreement, and your passport copy. They complete and submit the TM30 form. Same-day filing.

Foreign nationals can file a TM30 on their own behalf at the Immigration Bureau with: their passport, the lease agreement or letter from landlord confirming the address, and a completed TM30 form (available at Immigration or downloadable from immigration.go.th). Some Immigration offices accept this directly; others require the landlord signature.

The TM30 can be filed online at immigration.go.th (or the TM30 online portal). The online system requires account registration by the housemaster. Landlords with multiple foreign tenants often set this up. You can request your landlord use this route.

Your TM30 is tied to a specific address AND a specific entry into Thailand — and it resets on either trigger changing, not just one of them. When you return from any international trip (even a short one), a new TM30 must be filed for your return to the address; this is the most common cause of TM30 problems, since long-stay residents who travel internationally and return often assume their old TM30 is still valid, and it is not. The second, less-obvious trigger: moving to a new address within Thailand, with no international travel involved, also requires a fresh TM30 at the new address. Digital nomads who change apartments monthly need a new report every single time — the obligation follows the address, not just the border crossing. Short-term rentals booked via Airbnb rather than through a hotel or registered host carry the same risk, since informal hosts frequently don't understand or fulfil the reporting obligation at all.

We check TM30 status before any Immigration office visit or extension application and advise on what to do if it is not current. For clients without cooperative landlords, we can assist with the self-filing process.

Before signing a lease or booking a longer stay, ask your landlord or property manager directly whether they will file the TM30 and get that confirmation in writing if possible — a landlord who hesitates or seems unfamiliar with the requirement is a real warning sign, not a minor inconvenience to work around later. For condos specifically, the juristic person (building management) often handles TM30 filing on behalf of individual unit owners, so confirming with them directly can be faster than chasing an individual landlord. If you move apartments, even within the same building, treat it as a fresh TM30 trigger and confirm it's been filed before you need it for an extension or 90-day report — don't wait until Immigration tells you it's missing.
