90-Day Report, TM.30 and Re-entry Permit: Three Duties Expats Confuse

These are three separate obligations. The 90-day report is your own notice of address after every 90 days of continuous stay. TM.30 is a notice the owner or host of your accommodation gives when a foreigner stays there. A re-entry permit is permission you obtain before leaving Thailand so your current extension of stay is not cancelled when you exit. Doing one never replaces another.

What is the 90-day report?

Any foreigner staying in Thailand for more than 90 consecutive days must notify immigration of their current address at the end of each 90-day period. It can be filed in person, by an authorised representative, by registered post or online where the online system accepts the filing. Leaving Thailand resets the count: the first report falls due 90 days after your latest entry.

What is TM.30?

TM.30 is the residence notification that the house master, owner, landlord or hotel must give immigration when a foreign national stays at their premises. Hotels file it routinely. In private rentals and family homes the duty sits with the owner or host, but in practice the foreigner often prepares it, because immigration offices commonly ask to see a current TM.30 receipt before processing an extension or a 90-day report.

What is a re-entry permit?

An extension of stay is ordinarily cancelled when you leave Thailand. A single or multiple re-entry permit, obtained before departure at an immigration office or at the airport counter where available, keeps that permission alive so you can return on the same extension. Holders of some visa types, such as the LTR, are covered differently, so confirm the rule for your own status.

Side-by-side comparison

Who files — 90-day report: the foreigner (or a representative). TM.30: the owner or host. Re-entry permit: the foreigner.
When — 90-day report: every 90 days of continuous stay. TM.30: when the foreigner starts staying at the address, and commonly again after returning from abroad. Re-entry permit: before every departure you need to protect your extension.
Consequence of missing it — 90-day report and TM.30: an administrative fine and possible delays at your next application. Re-entry permit: your extension is cancelled on exit and you must start a new visa process.

How we keep the three in order

We set a calendar for each client's 90-day dates, check that a current TM.30 receipt exists for the actual address before any filing, and remind clients to obtain a re-entry permit before planned travel. Online filings are attempted first; when the system rejects them, a field representative files in person at the responsible office.

Frequently asked

Does leaving Thailand count as my 90-day report?

Not as a report, but leaving and re-entering restarts the 90-day count from your new entry date.

My landlord refuses to file TM.30. What can I do?

The legal duty is the owner's, but you can usually prepare the form with the owner's documents and file it with their authorisation. Ask the local office what it accepts.

If I forget the re-entry permit, can I fix it after leaving?

No. Once you exit without one, the extension is normally cancelled and cannot be restored from abroad.
