Of all the small pieces of paperwork that trip up foreigners in Thailand, TM30 causes more confusion than almost anything else. It’s not a visa. It’s not something you apply for yourself in most cases. And yet it can quietly hold up a visa extension, a 90-day report, or a bank account application if it’s missing — even though, technically, filing it usually isn’t even your legal responsibility.

This guide explains exactly what TM30 is, who’s actually responsible for filing it, when it’s required, how it connects to your other immigration obligations, and what to do if it’s been missed.

1. What TM30 actually is

TM30 is a notification form, filed with Thai Immigration under Section 38 of the Immigration Act, that officially records where a foreign national is residing in Thailand. Its formal name is the “Notification Form for House-Master, Owner or the Possessor of the Residence where an Alien has Stayed” — a mouthful that hints at the key detail buried in the name: it’s a notification made by the person or business hosting you, not something you fill in about yourself in most everyday situations.

In plain terms: whenever a foreign national moves into a residence in Thailand — a hotel, a rented condo, a rented house, or a property they own themselves — the law requires the accommodation to be reported to immigration within a set timeframe. It’s an address-tracking requirement, not a visa, and it doesn’t grant or extend any permission to stay.

2. Who is legally responsible for filing it

This is the single most misunderstood part of TM30, so it’s worth stating clearly: the legal duty to file sits with the “house-master, owner, or possessor of the residence” — in practice, your landlord, your hotel, your condo’s juristic person, or you yourself if you own the property outright.

You, as the foreign national staying there, are generally not the one who’s supposed to file it. But as the next few sections make clear, that legal technicality doesn’t protect you from the practical consequences if it doesn’t get filed.

3. When TM30 is required

TM30 needs to be filed within 24 hours of a foreign national taking up residence at an address, and this applies more broadly than most people expect:

• Your very first arrival in Thailand and check-in to any accommodation
• Any time you move to a new address within Thailand, including a temporary hotel stay during a trip to another province
• Returning to your usual residence after a trip abroad, in some interpretations and enforcement practices — this varies by office, so it’s worth confirming locally

It applies uniformly whether the property is a hotel, a serviced apartment, a rented condo, a rented house, or a property owned by a Thai or foreign national — there’s no exemption based on the type of accommodation.

4. How TM30 is filed

There are two main routes:

• In person — the property owner, landlord, or manager visits the local immigration office with the completed form and a copy of the foreign national’s passport (biodata page and current visa/entry stamp)
• Online — via the official TM30 portal (tm30.immigration.go.th), which property owners can register for and use to file electronically, avoiding a trip to the immigration office

Hotels and serviced apartments almost always use the online system as a matter of routine, since they’re processing check-ins constantly. Individual landlords are far less consistent — some file online, some go in person, and some simply don’t file at all unless specifically asked to.

5. Hotels vs private landlords vs condos you own

Hotels and serviced apartments

File automatically as part of check-in, almost without exception, since it’s built into their standard operating procedure and they process it in bulk daily.

Private landlords (condo or house rental)

Legally required to file within 24 hours of your move-in, but compliance is inconsistent. Many landlords, particularly for informal or long-standing rentals, are unaware of the requirement or simply don’t prioritise it.

Property you own yourself

If you own the property you’re living in, you become the “owner” for the purposes of this rule, and the responsibility to register on the TM30 portal and file the notification falls to you directly.

6. Why TM30 matters even though it’s not your legal duty

This is the part that catches so many people off guard. Even though the legal obligation to file sits with your landlord or property owner, immigration offices routinely ask for a current TM30 receipt when processing things that very much are your responsibility:

• Visa extensions and renewals
• 90-day address reports
• Re-entry permit applications, in some cases
• Opening or maintaining certain bank accounts

If the TM30 on file is missing, outdated, or shows the wrong address, these processes can be delayed or refused — regardless of whether the failure to file was technically your fault. In practice, you carry the consequences of someone else’s compliance gap, which is exactly why it’s worth actively checking rather than assuming it’s been handled.

7. How TM30 connects to 90-day reporting

TM30 and the 90-day report are frequently confused, but they’re different things that happen to interact closely:

• TM30 is filed by your landlord/property owner and records your address, triggered by a move-in
• The 90-day report (TM47) is filed by you, and confirms your continued residence at that address every 90 consecutive days

The two are linked in the system: if your most recent TM30 doesn’t match the address you’re reporting under your 90-day cycle, your TM47 submission — particularly online — can be rejected outright. This is one of the most common reasons an online 90-day report fails without an obvious explanation.

8. How TM30 connects to visa extensions

Immigration officers frequently request your TM30 receipt as supporting evidence for a visa extension application — it’s treated as part of confirming that the address information on your file is current and accurate. A missing or outdated TM30 is a genuinely common, entirely avoidable reason an extension gets delayed or bounced back for correction, adding an unwelcome extra trip to the immigration office right when you’re trying to get your renewal finalised.

9. What happens if TM30 is never filed

In practice, most foreigners discover a TM30 problem indirectly — not because anyone proactively flags it, but because it surfaces while they’re at the immigration office for something else, like a 90-day report or an extension. At that point, one of two things typically happens: the officer asks for the TM30 to be filed (or corrected) before proceeding, or the process is delayed while it’s sorted out.

Enforcement intensity varies noticeably by location — Bangkok and major expat/tourist areas (Chiang Mai, Phuket, Koh Samui, Pattaya) tend to enforce more consistently than smaller provincial offices, though this can change without much notice.

10. Penalties, explained clearly

The exact figures vary somewhat between sources and have shifted over recent years, which is a useful reminder in itself: don’t rely on a remembered number, confirm the current fine with your local immigration office if it becomes relevant to your situation.

11. What to do if your landlord won’t file it

If you’ve asked your landlord to file or correct a TM30 and they’re unresponsive or unaware of the requirement, a few practical options:

• Politely explain the specific requirement and, if possible, share the online portal link — many landlords simply don’t know the rule exists or haven’t dealt with foreign tenants before
• Offer to accompany them, or provide the documents (passport copy, entry stamp) needed to make it a five-minute task for them
• If the landlord genuinely won’t cooperate, some foreigners visit the immigration office directly to explain the situation — officers have discretion here, and outcomes vary, but a proactive, honest approach is generally received better than showing up at your next extension appointment with no TM30 on file and no explanation
• If you’re on a managed program (such as Thailand Privilege) or working with a visa agent, they can sometimes help coordinate directly with an unresponsive landlord

12. What to do if you own your own property

If you own the condo or house you live in, register on the TM30 online portal in your own name as the property owner, and file your own notification within 24 hours of taking up residence (and again after any trip that involved staying elsewhere). This is a one-time registration setup, after which subsequent filings are considerably quicker.

13. Travelling within Thailand and TM30

A detail that surprises many long-term residents: TM30 obligations aren’t limited to your first arrival in the country. Staying in a hotel elsewhere in Thailand technically triggers a new TM30 filing at that hotel, and returning home can, in some interpretations, warrant a fresh filing at your regular address too. In practice, this is inconsistently enforced for short domestic trips, but it’s the underlying reason the “hotel filed a TM30 that overwrote my home address” problem described earlier happens as often as it does.

14. How to check if your TM30 is current

There’s no single, universally reliable self-service way for a tenant to check their own TM30 status online in real time, since the filing itself is done by the property side. The most reliable approaches are:

• Ask your landlord or hotel directly for a copy or confirmation of the TM30 receipt whenever you move in
• Keep every TM30 receipt you’re given, physical or digital, in the same folder as your other immigration documents
• If you’re unsure, raise it proactively at your immigration office well before you need it for an extension or report, rather than discovering a problem on the day of a deadline

15. Common mistakes

• Assuming a signed lease means TM30 has been filed. A rental agreement and a TM30 filing are two completely separate things.
• Not asking for a TM30 receipt when checking into a hotel, then having no record if it’s needed later.
• Overlooking that a domestic trip can overwrite your registered address, then being confused when a 90-day report or extension gets rejected for an address mismatch.
• Assuming that because filing isn’t your legal duty, it isn’t your problem — practically, it very much becomes your problem at the immigration counter.
• Waiting until an extension or 90-day report to discover a TM30 issue, rather than checking proactively after any move or trip.
• Owning property and not realising you’re now personally responsible for your own TM30 filings.

16. Frequently asked questions

17. Practical tips

• Always ask for a TM30 receipt the moment you move into any new accommodation — hotel, rental, or your own property — and keep it filed alongside your other immigration documents.
• Confirm with your landlord directly, in writing (even just a message), that they’ve filed it rather than assuming a lease signing covers it.
• After any domestic trip involving a hotel stay, check that your home address TM30 is current again before your next 90-day report or extension is due.
• If you own your property, register on the online TM30 portal early, well before you need to rely on it for an extension or report.
• Raise any doubt proactively at your local immigration office, rather than discovering a TM30 problem for the first time on the day of a deadline-sensitive appointment.
