The TM30 is the address report Thai immigration requires whenever a foreigner stays at a property. It sounds like paperwork trivia — until a Bangkok immigration office refuses your extension because it was never filed. Here's what it is, who files it, and how to stay clean.
The TM30 is a notification form under the Immigration Act. The owner or possessor of a residence — a landlord, condo owner, hotel, or the foreigner themselves if they own the property — must report that a foreigner is staying there. It is separate from your visa and separate from the 90-day report.
Late filing carries a fine of up to ฿2,000 (and the foreigner can be fined too). More importantly, many immigration offices — especially in Bangkok — will not process a visa extension until the TM30 is on file. That's how a ฿1,000 form ends up blocking a ฿18,000 extension.
This is the most common problem we see. We can file on your behalf with the right documents (or you can file as the resident in most offices). Either way, it's solvable — just don't walk into an extension appointment without it.
It's tied to your stay at that address. It doesn't need annual renewal, but it must be re-filed when you move or return from a trip abroad.
No. The TM30 reports your address to immigration; the 90-day report is a check-in every 90 days of continuous stay. Long-stay visa holders do both. See our 90-day reporting guide.
Hotels file it for you automatically. If you're staying in a private rental, yes — the host should file it within 24 hours of your arrival.
