The duty and whose it is
Under the Immigration Act, the housemaster, owner or possessor of a residence must notify immigration within 24 hours when a foreigner takes up residence on the premises. That is the TM30. For hotels the duty is automated and invisible, handled through the operator's registration systems. For private landlords, condo owners and even foreign homeowners hosting themselves, it is a real filing with real deadlines: online through the immigration portal, or on paper at the local office. The foreigner is not the obligated party, but immigration's practical lever is the foreigner, because the TM30 record is what proves to the system where you live.
Current practice requires a fresh notification when you move to a new address, and after re-entering Thailand from abroad if your registered address has changed. Enforcement intensity varies by province and has softened since the strictest period, but the underlying requirement has not gone anywhere, and offices differ in how rigidly they apply it.
Why it gates everything
Immigration offices use the TM30 record as the proof-of-address layer beneath a series of services foreigners eventually need:
- Residence certificates: the document that certifies your address, required for a Thai driving licence, vehicle registration, and by most banks for account opening. No current TM30 on file, no certificate.
- Bank accounts: with banking access already tightened under anti-money-laundering pressure, the working chain at many branches is TM30, then residence certificate, then account. A missing first link fails the whole chain.
- Extensions of stay and 90-day reports: many offices check the TM30 before accepting an annual extension or a 90-day report, and will send you away to fix it first, sometimes with a fine attached.
- Driving licences and other provincial services that key off the residence certificate.
The pattern is worth internalising: the TM30 rarely causes a problem on its own timeline. It causes problems on yours, surfacing days before a licence renewal or in the middle of a banking appointment.
Who files what, in practice
| Living situation | Who must file | What usually goes wrong |
|---|---|---|
| Hotel or serviced apartment | The operator, automatically | Nothing, which is why problems start when you move out |
| Rented condo or house | The landlord or their agent | Absent or offshore owners who never file, or filed once years ago |
| Property you own | You, as your own housemaster | Owners assume the duty belongs to someone else |
| Staying with family or friends | The Thai householder | Nobody realises a filing is due at all |
Enforcement varies by office and has relaxed since its strictest period, when re-notification was demanded after every domestic trip. The current mainstream position requires notification on taking up a new residence and after returning from abroad where the address record needs refreshing, but individual offices interpret this differently, and the office that governs you is the one covering your address, not the friendliest one in the province. The safe habit is simple: whenever your address or your passport's entry stamp changes, make sure the TM30 record still matches reality.
How to check and fix it
Checking is straightforward: ask your landlord for the TM30 receipt or the confirmation from the online system, or ask at your immigration office whether a notification is on file for your current address. Fixing a gap means the housemaster filing, late if necessary; late filing carries a fine, commonly cited in the region of 800 to 2,000 baht, which is trivial against the disruption of a blocked extension. Where a landlord is absent or unwilling, practical solutions exist: many offices accept filings from an authorised agent holding the owner's documents, and lease negotiations for foreign tenants should simply include TM30 cooperation as a stated obligation, with the receipt handed over at move-in.
Foreigners who own their own condo are their own housemaster and must file for themselves, including after returning from trips abroad where required. This catches out owners who assumed the rule was only about landlords.
Running it as routine
Treated as routine, the TM30 is ten minutes of administration a year. We build it into every client relocation as standard: filing verified at move-in, receipts held on file, re-notifications handled after travel where the local office expects them, and the downstream documents, residence certificates, licences, banking letters, sequenced so nothing is ever requested from an office that has grounds to say no. The clients who never hear the word TM30 are the ones for whom it was handled properly.
