TM30 is one of the more confusing pieces of Thai immigration compliance, largely because the legal responsibility sits with your landlord, but the practical consequences of it going wrong land squarely on you as the foreign tenant.

What TM30 actually is

TM30, formally the Notification of Residence for Foreigners, is a legal requirement under Section 38 of the Immigration Act obligating whoever hosts a foreigner, a landlord, property owner, or hotel manager, to notify immigration within 24 hours of that foreigner arriving at the property. This applies to every kind of accommodation: condos, houses, hotels, serviced apartments, even staying with a Thai friend. Hotels and licensed serviced apartments generally handle this automatically as part of check-in; individual landlords renting to foreign tenants carry the same legal duty.

Whose responsibility it really is

Legally, filing TM30 is your landlord’s job, not yours. In practice, though, you’re the one who suffers if it’s missing, since immigration checks TM30 records before processing visa extensions, 90-day reports, and re-entry permit applications. If your landlord never files it, or files it incorrectly, you’re the person turned away at the immigration counter, which is exactly why most long-term residents learn to verify this themselves rather than simply trusting it happened.

The requirement that catches people out

This is genuinely worth understanding clearly: every time you leave Thailand and re-enter, your TM30 registration is effectively reset. Even returning to the exact same address you’ve lived at for years technically requires a fresh filing within 24 hours of your return, referencing your new entry stamp. A weekend trip to a neighbouring country, a visa run, a short flight home, each one triggers this requirement afresh. Enforcement of this specific trigger varies by immigration office, some are stricter than others, but the safest approach is having your landlord refile after any trip that involved staying elsewhere overnight.

Why address mismatches cause rejected 90-day reports

TM30 and your 90-day report (TM47) are separate filings, but they’re connected: if you travelled and stayed at a hotel in another province, that hotel’s TM30 filing becomes your latest registered address in the system. When you then try to submit your 90-day report from your actual home address, the system rejects it because the addresses don’t match. The fix is straightforward once you know it’s happening: have your home landlord (or yourself, if you own the property) file a fresh TM30 for your return date, once the addresses align, your 90-day report will go through.

If you own your own property

A detail that catches many owners off guard: the TM30 obligation attaches to the property, not to a landlord-tenant relationship, so if you own your home in Thailand, you still need a TM30 filed, effectively reporting yourself. There’s no exemption simply because you’re the owner rather than a tenant.

What to do if your landlord won’t cooperate

Some landlords, particularly those unfamiliar with renting to foreigners, are unaware of the requirement or reluctant to file. If this happens, you have real options: file it yourself online through the official TM30 portal (tm30.immigration.go.th), visit your local immigration office in person with a letter of authorisation from your landlord, or engage a visa agent to handle it on your behalf. Don’t simply wait and hope it resolves itself, proactively ensuring it’s filed protects your own immigration standing regardless of your landlord’s cooperation.

Penalties for both sides

Landlords face fines of up to 10,000 THB for failing to file. Foreign tenants can be fined up to 2,000 THB for failing to ensure the filing was actually made. Beyond the direct fines, a missing or mismatched TM30 can delay or block visa extensions, 90-day reports, and re-entry permits entirely, often at the worst possible moment, mid-appointment at an immigration office.

Practical habits worth adopting

Keep every TM30 receipt you’re given, you may need to show it for visa extensions, 90-day reports, or even hospital insurance claims. If you’re renting long-term, ask your landlord directly and get their TM30 responsibility written into your lease agreement before signing. Buildings with a management office or juristic person almost always handle this as standard, worth factoring into your decision if TM30 headaches are a genuine concern.

Final thoughts

TM30 is technically your landlord’s obligation, but treating it as something worth actively verifying yourself, rather than simply assuming it’s handled, avoids the genuine frustration of discovering it’s missing at the exact moment you need it for a visa extension or 90-day report. A few minutes of proactive checking after each trip saves considerably more hassle later.
