90-Day Reporting, Re-entry Permits and Extensions
The admin you take on once you live there.

Information only — not legal, tax, financial, insurance or medical advice.
Thailand’s visa, tax, healthcare and legal rules change, sometimes at short notice. Always confirm anything important with an official source or a qualified professional before you act on it. This page was last reviewed on 1 August 2026.
None of this is hard. All of it is easy to get wrong through inattention, and the consequences are fines and awkward conversations that are entirely avoidable.
90-day reporting
If you stay in Thailand continuously on a long-stay permission, you must report your address periodically. It is a notification of where you live, not a re-application for anything, and it can typically be done in person, by post, or online depending on your office and status.
- The clock is based on continuous stay — leaving and returning generally resets it.
- There is a window either side of the due date; do not leave it to the last day.
- The online system is convenient when it works, but keep a fallback plan.
- Keep the receipt slip. You will be asked for it at your next extension.
Re-entry permits
Making the annual extension painless
- Ask your office for their current document list in writing, well before you need it.
- Keep a folder of everything from last year — it is the best guide to what they will want.
- Photocopy and sign more than you think you need. Bring passport photos.
- Go early in the day, and never on the day before a public holiday.
- Diarise next year's date on the way out of the building.
