The 90-day report & TM30, explained.

What it is & why it matters

Thailand has two address-reporting rules that sound similar and confuse almost every new long-stay resident. The TM30 is a one-off notification, filed within 24 hours of you moving into an address, telling Immigration where you live — your landlord or condo juristic office usually files it. The 90-day report is a recurring confirmation that you, a foreigner on a long-stay visa, are still living at your reported address, filed every 90 days. They are not the same thing, you may need proof of both for visa extensions, and missing them can mean fines, so it pays to understand them early.

Step by step

1. When you move in, confirm your landlord or the condo juristic office files the TM30 within 24 hours — and get a copy of the receipt for your records.
2. If you're on a long-stay visa, note the date you entered (or your last report) — your first 90-day report is due around 90 days later.
3. File the 90-day report by your chosen method: online via the Immigration Bureau system, by post (sent ahead of the deadline), or in person at your local Immigration office.
4. You can usually file the 90-day report within a window starting about two weeks before the due date — don't wait until the last day in case the online system rejects you.
5. Keep every receipt. Immigration and the Land Office often want proof of address history for extensions and property matters.
6. Re-file the TM30 each time you change address or after certain re-entries, and reset your 90-day clock accordingly.

What it costs

Mistakes to avoid

• Assuming the TM30 and the 90-day report are the same filing — they're separate and both can be required.
• Believing the 90-day report resets your visa or extends your stay. It does neither; it's purely an address confirmation.
• Letting the deadline slip because you assumed the landlord handled everything — the 90-day report is your responsibility, not theirs.
• Leaving online filing to the final day, when the system may reject you and leave no time to file in person.

Pro tips

• The LTR visa relaxes 90-day reporting to once a year and eases some of this admin — worth checking if you qualify.
• Set a recurring calendar reminder two weeks before each 90-day due date.
• Leaving and re-entering Thailand can reset or affect your 90-day clock — check your latest entry stamp.
