What is TM30?
The TM30 is an official notification form that registers the address of a foreign national staying in Thailand. It is filed by the property owner or manager (not the foreigner) with the local immigration office within 24 hours of the foreigner's arrival or relocation.
The TM30 is not a visa extension or a separate permission document. It is simply an address registration system that allows Thai immigration to track where foreigners are living. However, it is a mandatory compliance requirement, and the record must be current when you apply for visa extensions or renewals.
Who must file the TM30?
The legal obligation to file the TM30 falls on the property owner, landlord, or accommodation manager. This means:
- If you rent a house or apartment, your landlord or property manager files the TM30
- If you own your property, you file the TM30 yourself
- If you stay in a hotel or resort, the management files it
- If you stay with a Thai friend or family member, they file it
As the foreigner, you are not legally required to submit the form yourself. However, you are responsible for ensuring it is filed. If your landlord fails to file it, you may face complications when renewing your visa or encounter immigration officials during a check.
The 24-hour deadline
The TM30 must be filed within 24 hours of your arrival at an address. This 24-hour period begins when you physically occupy the accommodation, not when you sign a lease or agreement.
The deadline applies in the following situations:
- Your first arrival in Thailand (if you have a long-stay visa)
- When you move to a new address within Thailand
- When you return to Thailand after leaving the country
In practice, many landlords file the TM30 on the same day you arrive or within a few days. Immigration is generally lenient with the 24-hour deadline as long as the registration is current, but it is technically a requirement.
Important: When you change accommodation, your landlord must file a new TM30 within 24 hours of your move. You cannot rely on an old TM30 from a previous address. This is particularly important for visa extensions.
How TM30 is filed
In-person filing at immigration office
Most landlords file the TM30 in person at the local immigration office. They complete the form, attach a photocopy of your passport, and submit it. The office processes it immediately and stamps the form as proof of registration.
Online filing
Thailand has an online TM30 system (tm30.immigration.go.th) that allows property owners to file electronically. This is more convenient and avoids queues, but not all landlords use the online system.
What happens if your landlord doesn't file?
If your landlord fails to file the TM30, you have several options:
- Ask your landlord to file it immediately
- File it yourself using the online system (though legally the landlord is responsible)
- Contact immigration to check your status and ask what action is needed
In most cases, a landlord can file a late TM30 and immigration will accept it. However, if you are caught without current TM30 registration during an immigration check, you may face fines.
Verifying your TM30 registration
You can verify that your TM30 has been filed by:
- Asking your landlord for proof (a stamped copy of the TM30 form)
- Visiting the immigration office and asking to check your record
- Checking the online system (if you have login credentials)
Before applying for a visa extension, it is wise to verify that your TM30 is current. Immigration will check this when processing your extension, and a missing or outdated registration can delay or deny your application.
If your landlord has not filed the TM30 or you need to verify your registration, visit the main immigration office at 71 Moo 3, Airport Road, Suthep Sub-district, Muang District, Chiang Mai 50200. Staff can check your current address on file and advise if action is needed. You may also contact Central Festival secondary office to verify (services subject to change).
TM30 and visa extensions
When you apply for a visa extension or renewal, immigration will check your TM30 registration. If your address on file does not match your current residence, or if there is no current TM30 on record, your extension application may be denied or delayed.
This is a common reason for visa extension rejections. Always ensure your TM30 is current before applying for an extension. If you have recently moved, have your new landlord file the TM30 as soon as possible.
