TM30: address notification

TM30 notifies immigration of where you’re living whenever you move address or re-enter the country. If you rent, your landlord or the condo juristic office typically files this on your behalf — confirm they actually do it, since an unfiled TM30 can delay your next visa extension even though the failure wasn’t yours to begin with. This is worth confirming explicitly rather than assuming, ideally in writing or at minimum a clear verbal confirmation at lease signing, since it’s genuinely common for this to fall through the cracks with less experienced or less organized landlords. If renting a private house directly without a managing office, the obligation falls to you, and it’s worth filing promptly after each move rather than treating it as optional.

90-day reporting

Every long-term visa holder must confirm their current address to immigration every 90 days, regardless of visa type. Three ways to file:

  • Online through the Immigration Bureau’s system, the most convenient option once set up, though initial registration for online reporting requires an in-person visit first
  • By mail to your local immigration office, a reasonable option if you’re comfortable with Thai postal timing and want to avoid a trip
  • In person at Prachuap Khiri Khan Immigration, the most reliable method if you want immediate confirmation the report was received

This is a simple confirmation, not a re-application — but missing the window creates complications and can result in a fine at your next in-person visit, even though the report itself takes only minutes once you know the process.

Re-entry resets the clock: every time you return from abroad, a new TM30 is needed and your 90-day count restarts. Keep copies of every receipt slip — immigration may ask for them at your extension.

Staying on top of it

Set a recurring calendar reminder a week before each 90-day deadline rather than tracking it manually — this is consistently cited as the single most commonly missed piece of ongoing visa admin among long-term expats, not because it’s complicated, but because it’s easy to lose track of amid everything else, particularly since the 90-day cycle doesn’t align neatly with any other recurring date like a monthly bill or annual visa renewal.

What happens if you travel internationally

Every re-entry into Thailand resets the 90-day clock, which can work in your favor if you travel internationally with any regularity — frequent travelers sometimes find they rarely need to file a standalone 90-day report at all, since international trips naturally reset the countdown. Worth tracking your actual re-entry dates rather than assuming, though, since an unusually long stretch without international travel can bring the 90-day deadline up faster than expected.

The bigger compliance picture

TM30 and 90-day reporting are genuinely the two pieces of ongoing admin that trip up long-term expats more than the visa extension itself — neither is complicated individually, but both require consistent attention over years of residence in a way that’s easy to become lax about once the novelty of “living abroad” wears into routine.

Where this connects

Next Step Hua Hin handles TM30 and 90-day reporting routinely for long-term residents who’d rather not track it themselves.

Frequently asked questions

Who is responsible for TM30?

Legally the property owner or host, but in practice immigration often checks with the foreigner. Make sure your landlord files it and give them your passport details promptly.

When can I file my 90-day report?

From 15 days before to 7 days after the due date. Filing in person, by an agent or online are all possible.

Do I need to report if I left Thailand?

No — leaving the country resets the 90-day count. Your next report is due 90 days after re-entry.
