A foreign guest returns from overseas, moves from one condo to another, or checks into your property after staying elsewhere. The question arrives quickly: does this require a new TM30? This guide to address change reporting explains the practical answer for property owners, hosts, managers, and foreign residents responsible for accommodation reporting in Thailand.
The short version is simple: when a foreign national stays at a new address, the person responsible for that property generally needs to report their arrival through TM30. The details matter, though. Confusion usually comes from mixing up TM30 accommodation reporting with a foreign resident's separate 90-day address reporting obligation.
What address change reporting means for TM30
TM30 is the notification submitted by the householder, property owner, landlord, hotel, or accommodation manager when a foreign national stays at their premises. It tells Thai Immigration where that person is currently staying.
For most hosts, “address change reporting” means reporting a foreign guest or resident at your address after they have moved there or returned there. It is not usually a form where the guest reports their own move. The reporting duty normally sits with the accommodation provider or person in control of the premises.
This distinction prevents a common mistake. A foreign resident may be responsible for their own 90-day report, depending on their immigration status and circumstances. But the TM30 concerns the place they are staying and is generally handled by the host, landlord, hotel, or property manager.
When a new TM30 report is usually needed
A new report is generally needed when a foreign national arrives at your property and stays there. That includes a first check-in, a move from another Thai address, or a return from travel outside Thailand.
For example, a tenant lives in Bangkok, visits Vietnam for a week, and returns to the same apartment. The responsible party may need to file a TM30 arrival notification again after that return. Similarly, if a tenant leaves one condo and begins staying at another, the responsible party at the new condo should report them.
Short stays count too. A guest does not need to sign a long lease before reporting becomes relevant. If they are staying overnight at your house, apartment, guest house, hotel, or rental property, treat the arrival as something that may need a TM30 filing.
The exact local practice can vary, and immigration rules and enforcement procedures can change. If there is any uncertainty about a specific situation, it is safer to confirm the current requirement with the relevant Immigration office rather than assume an earlier filing still covers a new stay.
Situations that commonly trigger reporting
The most common triggers are easy to recognize:
A foreign guest checks into your hotel, guest house, or serviced apartment.A foreign tenant moves into a condo, house, or apartment you own or manage.A foreign resident returns to your property after leaving Thailand.A foreign guest moves to your property from another address in Thailand.A homeowner hosts a foreign friend, partner, family member, or long-term resident overnight.
The practical rule is to focus on the current place of stay. If your property has become the foreign national's accommodation, the person responsible for that property should assess and complete the TM30 requirement promptly.
The 24-hour timing rule
TM30 reporting is commonly required within 24 hours of the foreign national's arrival at the accommodation. For busy operators, that window can disappear fast. A late-night check-in, a holiday, or a government portal that will not load can turn a simple administrative task into an avoidable compliance concern.
Do not wait until a visa extension, a 90-day report, or a request from the tenant. Those events may expose an earlier missing TM30, but they are not the trigger. The trigger is the arrival or stay at the property.
For hotels and high-volume accommodation businesses, the best approach is to build reporting into check-in. Capture the passport details when the guest arrives, verify the property address once, and submit before the deadline. For landlords with one or two foreign tenants, a simple reminder process is often enough, especially when a tenant returns from international travel.
Information you need before submitting
A complete TM30 submission depends on accurate guest information and property details. A clear passport photo or scan is often the fastest starting point because it contains much of the identifying data required for the form.
Check that the passport image is readable. The full identification page should be visible, with the guest's name, nationality, passport number, date of birth, and other printed details clear. Blurry photos, glare across the passport number, and cropped pages create delays because the information must be corrected before submission.
You also need the accommodation information: the correct property address, province, district, subdistrict, and the arrival date. For a hotel or managed building, keep these details standardized in your internal process. Small variations in an address may seem harmless, but consistency makes reporting easier and helps avoid records being filed under the wrong property.
If you manage several units, identify the exact room, building, or unit number where applicable. The more organized the property data is before check-in, the less time your team spends searching for it when the 24-hour clock is running.
A practical process for address change reporting
The most reliable workflow is not complicated. First, confirm that the person is actually staying at your property and record their arrival date. Next, collect a readable passport image and verify the unit or address. Then submit the TM30 and retain the confirmation or receipt.
For recurring tenants, keep a simple record of international departures and returns when possible. You do not need to chase people unnecessarily, but it helps to tell foreign residents at move-in that they should notify you when they return from abroad. This gives you enough time to complete the required reporting instead of finding out later during a visa-related appointment.
For accommodation operators, assign clear ownership. If the front desk collects passport details but a manager submits TM30 forms at the end of the day, make sure there is a backup when that manager is unavailable. Compliance tasks fail most often because everyone assumes someone else has handled them.
Digital submission also changes the workload. Rather than manually copying passport details into a slow government interface, a service such as TM30.io can extract data from a passport image, prepare the form, submit it, and keep trying if the Immigration system is temporarily unavailable. That is especially useful when several arrivals need reporting at once or the official portal is unresponsive near a deadline.
Keep proof after submission
Submitting is only part of the job. Save the confirmation, receipt, or reference details in a place you can retrieve later. This matters if a guest is asked for evidence during a visa extension, if an officer requests clarification, or if a property manager changes.
For one property, a secure folder organized by guest name and arrival date may be enough. For a hotel or apartment business, use a consistent record system tied to the booking or unit number. Avoid relying only on a staff member's phone or inbox. If that person leaves, the compliance history should stay with the business.
Receipts also help resolve ordinary mistakes. If a guest says they were reported at a different address, or a date needs to be checked, you can review the filed record rather than trying to reconstruct events weeks later.
Common mistakes that create unnecessary problems
The first mistake is assuming a lease replaces TM30. A lease documents a rental arrangement, but it is not the same as notifying Immigration of a foreign national's stay. The second is treating an old report as permanent even after the resident has traveled abroad or changed accommodation.
Another frequent issue is submitting the wrong arrival date. Use the date the person arrived at your property, not the lease signing date, visa issue date, or the day you finally had time to file. If a guest arrives after midnight, record the actual arrival carefully.
Finally, do not confuse speed with guesswork. Filing quickly is useful, but names, passport numbers, nationality, and property details still need to be correct. A fast process should reduce manual work, not remove the final check.
Make reporting part of the stay, not a last-minute task
Address change reporting is easiest when it becomes a routine part of check-in and return travel. Ask for the passport image early, keep your property information ready, file within the required timeframe, and save the confirmation immediately.
That small habit protects the guest, the property, and the person responsible for reporting. More importantly, it keeps a straightforward administrative requirement from becoming a stressful problem at the exact moment someone needs immigration paperwork to go smoothly.
