Thailand's 90-day report confirms the address of a foreign national who has stayed in the country continuously beyond 90 days. It does not extend a visa, renew permission to stay, or replace the host's TM30 (host-filed foreign-resident address report).
When is the report due?
The official in-person window opens 15 days before the due date and runs through seven days after it. Postal and online routes have their own timing and acceptance conditions, so do not assume the full in-person window applies to every method.
Leaving Thailand ends that continuous-stay count. A new count begins after re-entry. A domestic trip does not reset it.
Use the date on your latest accepted receipt and entry history rather than counting from a visa label or work-permit date. Put reminders well before the deadline because online rejection can require an office visit.
Which documents and methods are used?
TM47 is the name of the foreign resident's 90-day notification form. For an in-person report, prepare the original passport and the copies or records requested by the responsible office, including identity, current permission to stay, latest entry, previous report, and current Thai address.
The Immigration Bureau offers an online portal for eligible repeat reporting. The system checks your data against the immigration record and sends an approval or rejection. Save the approved receipt, not only the submission screen.
The first report or a case with changed, incomplete, or mismatched records may need in-person handling. A representative or registered-post route can be available under official conditions. Use the immigration office serving your current address.
How does it differ from TM30?
TM30 is the host's foreign-resident accommodation report, normally filed when you arrive at an address. TM47 is your own recurring notification after 90 days of continuous stay.
The address should agree across the two systems. If you moved, resolve the accommodation report and current-address evidence before assuming the online 90-day system will accept the old details.
Keep every receipt in date order. The receipt shows the next notification date and provides evidence if the online history or passport record is questioned.
Common misconceptions
One misconception is that a visa extension completes the 90-day report. They are separate immigration actions unless the office explicitly processes both.
Another is that the report is required every three calendar months. The legal cycle follows 90 days of continuous presence and the accepted due date.
Summary
File Thailand's 90-day address notification on time through an eligible official route and retain the approved receipt.
Track continuous presence, use the correct local office, and keep TM30, TM47, passport, entry, and address details consistent.
