90-day reporting, TM30 and re-entry permits
Once your extension of stay is granted, three routine obligations remain. None of them is complicated, but missing one leads to fines or, in the case of re-entry permits, losing your extension.
90-day reporting
Foreigners staying in Thailand for more than 90 days in a row must notify Immigration of their address every 90 days. The form is called TM47. You can report:
- in person at the Immigration office that covers where you live
- by post, sent in advance
- online, through the Immigration Bureau's reporting website, once you have reported in person at least once at the same address
The report is due on the 90th day, and Immigration accepts it from 15 days before to 7 days after. A report counts from your last entry or last report. Leaving Thailand resets the count, so after you come back you start again from day one.
Late reporting leads to a fine. Keep the receipt slip each time, as Immigration may ask to see it.
TM30: the landlord's notification
The TM30 is a separate notice, filed by the owner or manager of the place you stay, telling Immigration that a foreigner is living there. It is meant to be filed within 24 hours of your arrival at the address, including after trips abroad. Hotels file automatically. For condos and houses, landlords or building managers file, often online.
In practice, Immigration offices often check for a TM30 receipt when you apply for your extension or report. Ask your landlord for a copy when you move in.
Re-entry permits
Your one-year extension of stay ends the moment you leave Thailand unless you hold a re-entry permit. You can get one:
- at an Immigration office before you travel
- at the airport, at the re-entry permit counter before passport control
A single re-entry permit costs 1,000 baht and a multiple re-entry permit costs 3,800 baht. Teachers who travel during every school holiday usually take the multiple permit.
Keeping track
Make a calendar note for each 90-day report and each extension renewal date. Keep scans of your passport pages, work permit, extension stamp, re-entry permit and TM30 receipt in one folder.
